AMOLED : Active Matrix Organic Light Emitting Diode



AMOLED stands for Active Matrix Organic Light Emitting Diode. AMOLED is a display technology OLED (Organic Light Emitting Diode). OLED is a solid device that consists of thin films. The films containing organic molecules that can produce light when powered.OLED is used as a screen in a device with a higher acuity levels and relatively low power consumption. AMOLED is issued by Samsung, a technology company based in South Korea (Seoul). As one of the largest technology companies in the world, Samsung launched the innovative touch screen AMOLED-based technology that became the first AMOLED touch screen. AMOLED technology is a form of development from the previous screen, known as Thin Film Transistor (TFT). This technology is the result of a combination of OLED technology and conventional active matrix TFT LCD. AMOLED is a form of development of ordinary passive OLED screen, which can turn any pixel with efficiently and directly. AMOLED technology has touch functionality (touchscreen) directly, rather than through the second layer on top of the screen. The new method is done through the addition of sensors to the organic cells of the LED. Touch interface is able to increase the thickness of the screen reaches a thousandth of a millimeter, so it will reduce the sharpness or dim the image, as if mounted in two panels.

AMOLED display has a brightness level (brightness) high in appearance. AMOLED technology packed RGB adjustment feature, which can make the color of the photo or video is more stable, so it looks brighter and sharper. This technology has a low level of energy consumption or saving power, so that power consumption is minimal, and the battery can last for a long time.
This technology is able to save 40 percent more power than others. Rate thinness of the screen reaches 0.001 mm. In addition the screen is even claimed to produce better black levels than others, though seen from the sun directly, the screen still looks bright and clear, and the color is still bright. AMOLED screen also does not require backlighting that has the ability to regulate how much pixels, with lower power consumption, even in large sizes. In addition, this screen also has a deeper contrast ratio than most other LCDs. The uniqueness of the shape AMOLED screen is a screen is able to adjust the brightness of the screen automatically. AMOLED is made faster response times when the phone turns on and off positions. Thinness and flexibility of the material used in this screen technology making factories can make the screen in varying sizes, from small to giant size though. For example, layarTV Plasma reached 150 inches in size to the smallest size on the phone. Besides the other advantages of this technology compared to LCD technology is that the AMOLED technology, to be seen by the human eye does not require a backlight light further.

weakness of this screen, that is making the screen is still quite pretty complicated. In addition, because the technology is still new, the price of devices that use this technology are also relatively expensive. Although the AMOLED screen offers a tempting range of sophistication, but it is not easy for the vendors to adopt AMOLED, because it has a component AMOLED prices are more expensive than the components on the previous screen. This, of course, make the vendors to re-think. That is the reason why some technologies, such as smartphones are relatively rare form of tablets equipped with AMOLED screen and still survive with a TFT screen, the goal is to reduce the selling price to the consumer. However, some vendors are able to produce their own AMOLED display technology is easier to apply this screen, such as Samsung and LG.

Organic Light-Emitting Diode (OLED)


Background
OLED technology invented by Eastman Kodak Company scientist, Dr. Ching W. Tang in 1979. Research in Indonesia on this technology began in 2005. OLED technology was created as aternatif that can outperform the previous generation display, liquid crystal display (Liquid Crystal Display or LCD). OLEDs have been developed and applied to the device display technology.
OLED Technology
OLED technology is an important tool in elektroluminensi. These technologies have the basic concept of the light beam generated by the device due to the applied electric field. OLED technology was developed to obtain a broad view, flexible, inexpensive and can be used as an efficient screen display for different purposes.
Number of colors of light emitted by the OLED devices evolve from one color to multi-color. This phenomenon is obtained by varying the voltage that is supplied to the OLED device so that the device has the prospect of becoming an alternative devices such as flat-screen display technology based on liquid crystals.
Layer structure
OLED structure consists of layers made of glass-indium tin oxide that serves as the positive electrode or anode, organic layers of aromatic diamine with a thickness of 750 nm, the light emitting layer made of metal complex compounds such as 8-hydroxyquinoline aluminum, and a negative electrode layer or cathodes made from an alloy of magnesium and silver by atomic ratio 10:1. Construction of the entire layer is not more than 500 nm, meaning same thin OLED with a sheet of paper.
Design tools
An important part of the OLED device is an electrode layer and a thin layer consisting of organic molecules as light-emitting both of which are arranged overlapping. The organic layer can dimendapkan with a relatively simple technique that plays coating (spin coating) while dimendapkan electrode layer using evaporation techniques (evaporation). Electrode layers made of metal or semi-transparent transparent as Indium Tin Oxide (ITO) or aluminum (Al). Properties of transparent allowing light from an optimal exit device structure.
working mechanism
Mechanism of action of OLED is if the electrode is given electric field, the work function cathode will go down and make the electrons move from the cathode into the conduction band in the organic layer. This situation resulted in the emergence hole (hole) in the valence band. Anode hole will push to move towards the valence band of organic matter. This situation resulted in the recombination of electrons and holes in the organic layer where the electrons will go down and unite with holes and provide excess energy in the form of a photon of light with a specific wavelength. Will eventually obtained one type of beam of light with a specific wavelength depends on the type of light-emitting materials are used.
Application
OLED technology development in Indonesia right with the reality that is the development of technologies that are tailored to the ability of a limited budget with efforts to obtain optimal results. OLED technology as an alternative display made as an effort to pursue tertinggalnya existing technology to avoid the further so as to reduce dependence on the use of technology products from industrialized countries.
In Indonesia, some of the technology display with OLED technology has entered into the market, ranging from lighting equipment, household consumption devices such as televisions, gadgets like mobile phones, keyboards (keyboards), digital cameras, digital watches, portable computer (laptop) , computer screen, to display information tools such as announcements in supermarkets, airports, hotels or hospitals.
Lighting equipment
OLED technology in the form of lighting equipment such as flashlights can be found in major cities in Indonesia. The light produced is not as bright as halogen lamp types but flashlights are energy efficient so the batteries used to last longer.

Mobile phones
Nokia 8800 sapphire arte mobile phone is one that adopts OLED display devices and has been marketed in Indonesia. The screen size is quite large ie 240 x 320 pixel OLED technology support 16 million colors make the images or the images it produces are very clear and beautiful as the original color.
Keyboard
Keyboard with OLED screen on its surface so as to show a letter or icon as if printed on the keyboard. Keyboard models already offered in Indonesia, namely models and Optimus Mini 3.
Digital watches
1.8-inch OLED display used in digital watches are marketed by Gubrak.com Indonesia. This product comes with a MP4 player (MP4 player), had 7 EQ modes to maximize the sound of music, sound recordings, display images in JPEG or GIF format, and watch movies.

The presence of OLED technology with a unique manufacturing process that shifts the position of LCD technology.
* OLED display new and exciting. The screen is made of a combination of colors in transparent glass so thin that light and flexible.* Ability to operate as an OLED light source that produces a bright white light when connected to a power source.* Low power consumption and are made of organic materials makes OLEDs as environment-friendly technologies.* Operating costs are relatively low and the assembly process is relatively simple compared to LCD. OLEDs can be printed onto a substrate in accordance with the technology of spray ink printer (inkjet printer).* It has a coverage area of ​​the color, brightness, and viewing angles are very wide. OLED pixels directly emit light while using technology LCD back light (backlight) so it does not emit actual colors.* OLEDs have a faster reaction time. The LCD display has a response time of 8-12 milliseconds, while OLED is less than 0.01 ms.* OLED can be operated in a wider temperature limits


OLED technology in Indonesia in general is still limited by several factors that should be developed further.

 
* Technical problems persist OLED namely the organic material is limited, about 14,000 hours compared to other flat screens that can reach 60,000 hours. In 2007, the last period OLED developed to 198,000 hours.
 
* Moisture can shorten the life of OLED. Materials in the OLED organic content can be damaged if exposed to water.* Development of the seal (improved sealing process) in OLED manufacturing practices can limit the display last time.* In a multi-color OLED devices present, the intensity of the light produced for a specific color not bright enough.* Prices of products tend to be expensive so it is still not affordable by the general public.

GPU (Graphics processig unit)

Graphics processing unit or GPU (or usually called visual processing unit or VPU) is a special prossesor for 3D graphics part of the microprocessor. This tool is used in embedded systems, mobile phones, personal computers, workstations, and game consoles. Modern GPUs are very efficient at manipulating computer graphics and parallel structure, making it more effective than the common functions that are used for trending CPU computation algorithm. On a personal computer (PC), are common GPU video card or motherboard. More from desktop and notebook computers have integrated GPUs, which are usually far than the one in the video card.
Now GPU also use in smartphones,  

AdrenoAdreno series which is made in the current ATI AMD subsidiary ATI imageon first referred to the series, circa 2002-2004 is at the beginning of the release of this GPU series. In 2008, AMD imageon sold to one of the leading manufacturers of processors, namely Quallcom. And now ATI / AMD only supports the architecture and development only. Now Adreno series is inherited from all the SOC (system on chip) made Quallcom. Adreno itself is also divided into several classes:* Adreno 130, which resides in the SOC Quallcom MSM7xxx series.* Adreno 200, which is at QSD8x50 (1st gen snapdragon, QSD is the code of the series snapdragon SOC) and MSM7x27 (MSM is code for SOC products quallcom for general series). Usually, this series Adreno Android handhelds used in low-end (low specs, with a 600-800 MHz processor).* Adreno 205 in QSD8x50A (1.3 GHz), MSM7x30 (800 MHz + L2 cache), MSM8x55 (1 GHz + L2 cache).* Adreno 220, is their latest flagship, I do not have a lot of info about the Adreno 220, but it seems to have a multi-core GPU (more than one processor core). This series and the Adreno 220 is typically used in handheld Android class Mid-End and High-End (a high specification, with a 1GHz processor above). 




PowerVRPowerVR Series is the first artificial logic video also enliven the VGA market, but as the dominance of NVIDIA and ATI video logic now only play in the world of mobile gadgets GPU. PowerVR itself is not in production in finished form by power logic, but they are only a draft architecture, which sold the license to many of the leading processor manufacturers such as NEC, Intel, Freescale, Texas Instruments and others.PowerVR Series alone now in its sixth series, his 2 game console ever used in the 1900's, the Dream cast and Sega Saturn. PowerVR SGX Series 5 is the series most often found on smartphones, SGX GPU 5 itself is elite in the world of smartphones, the world might be like BMW cars listed J.Seri SGX been used in a variety of smartphones and gadgets follows:* SOC A4/SGX535 (iPhone 4/ipod gen4/ipad)* SOC Hummingbird/SGX540 clock 200 (Samsung Galaxy S)* OMAP SOC 3/SGX530 series (Droid X, Motorola Defy, Samsung Galaxy SL, Motorola Mile 2,   Droid 2 and LG Optimus Black)* Intel GMA 500 and GMA 600 also uses SGX535 as onboard VGA intel atom* Varian next 5 series is SGXMP (MP here indicates the number of cores) SOC OMAP 4 (4430) / SGX540MP quadcore clocked 300 (Blackberry Playbook, LG Optimus 3D)
 
* SOC A5/SGX543MP2 (iPad 2)
 
* SGX543MP4, which is used in the Playstation Vita
 
* In addition, the next series of the gods, SGX544MP + OMAP 5 will be dual quadcore CPU that mnggunakan A15 (eagle platform) + dual CPU Cortex-M4 processor cores clocked with up to 2 GHz. 




MaliMali series, this GPU is made in the ARM architecture, though still rarely heard his name, but its power can not be underestimated. Mali GPU series outstanding from HDTVs, gaming consoles (PS3), up to a smartphone. Especially for smarphone, the series used is 400MP4 Mali (MP is the core indicators used). GPU is part of the SOC A9 1.2GHz Exynos dual-core CPU Samsung's Galaxy S II. Reportedly 400MP4 Mali is able to render almost equivalent to the PS3 and Xbox 360.GeForce ULPSeries GeForce ULP (ultra low power) is concentrated in that part of the GPU Tegra 2 SOC manufactured by NVIDIA. Geforce ULP uses quadcore 4 pixel shaders + 4 vertex shaders up to a total of 8 cores that are in it.If for determining the performance certainly did not escape Dr. SOC what used, so it is difficult to determine the point which is used for comparison because each GPU is very dependent on the performance and support SOCnya dr. For instance, SOC OMAP 4 series with SGX540 GPU vs quadcore Tegra 2 ULP GeForce GPU with 8core, hello who would win? When to see the number of cores, by naked eyes 8core candidate who will be on the GeForce ULP but when calculating the SOC capabilities trlihat OMAP 4 trnyata could bulldoze Tegra 2, not only from the benchmark results, framerate, javascript rendering, but within a matter of efficient use jg battere .This is not surprising because the OMAP 4 has a few secret weapons like supports dual channel DDR2 memory up to 1gb LP, where the new Tegra 2 is capable of using a single channel. Back lg SOC capabilities greatly determine the outcome, as well as Snapdragon with its core scorpion, would be defeated perform with Tegra 2? Not really, mainly for multimedia results which force snapdragon and Adreno indeed in optimizing on this side.Next obstacle in comparing these monsters are different ways of GPU rendering that performed on each platform, such as snapdragon SOC Adreno the usual rendering method (when passing limits) lower quality but maintain that framerate awake resolutions, while the Hummingbird GPU SGX540 renders purely using GPUnya force even fixed by turning on vsync. Though our eyes seen his performance is almost the same, the results were not much different framerate, but if vsync is turned off and compared the picture quality will be seen where the SGX540 benar2 monsters and very quick!It is also yet the driver used in the OS is a smartphone or gadget. So, it's hard to determine where the best GPU, because each GPU has its own advantages and disadvantages trsendiri and dependent on support from their respective SOC.

Membangun Jaringan LAN (kabel UTP)


Tutorial singkat ini cocok banget buat yang sedang mo bikin jaringan komputer 'MURAH' khususnya yang terdiri lebih dari 2 client, yang pake hub (jauh lebih murah ketimbang router :D). To the point! Apa sih kabel UTP itu? Kabel UTP itu adalah kabel khusus buat transmisi data. UTP, singkatan dari "Unshielded Twisted Pair". Disebut unshielded karena kurang tahan terhadap interferensi elektromagnetik. Dan disebut twisted pair soalnya di dalamnya terdapat pasangan kabel yang disusun spiral alias saling berlilitan. Ada 5 kategori kabel UTP. Dari kategori 1 sampai kategori 5. Untuk jaringan komputer yang terkenal adalah kategori 3 dan kategori 5. Kategori 3 bisa untuk transmisi data sampai 10 mbps, sedang kategori 5 sampai 100 mbps.
Nah klo cuman buat misal bikin jaringan komputer di kantor ato kampus ato warnet, paling ngirit ya pake yang kategori 3. Udah lebih dari cukup. Setau gue ada banyak merek yang beredar di pasaran, cuman yang terkenal bandel dan relatif murah adalah merek Belden - made in USA. Per meternya berkisar dari Rp. 1500 - 2000,- Kalau mau jatuh murah dan pakenya banyak beli aja yang satu kotak, panjangnya sekitar 150meteran.
Jangan lupa beli konektornya. Konektornya tuh bentuknya kayak colokan telepon cuman lebih besar. Bilang aja mo beli konektor RJ-45. Harganya klo ngecer sekitar Rp.2500,- an Foto RJ45 - Konektor untuk kabel UTP Foto RJ - 45 yang masih baru, belum di gencet pake tang Crimp Tool Satu lagi yang sangat penting, kamu kudu punya tang khusus buat masang konektor ke kabel UTP, istilah kerennya "crimp tool". Ini alat gunanya buat 'ngematiin' ato 'nanem' ato apalah istilahnya itu konektor ke kabel UTP. Jadi sekali udah di 'tang' udah ga bisa dicopot lagi itu konektor. Harganya memang agak mahal dibanding tang biasa. Antar Rp.75rb - 150rb. Dan klo mo lebih ok, biar ga nanggung tambah duit lagi sekitar 125rban buat beli lan tester. belinya yang merek dari taiwan aja. lebih murah. bentuknya tuh kayak kotak, dan ada lampu lednya 8 pasang, bisa kedap kedip. OK sekarang peralatan udah siap, gue mulai aja. Secara umum pemasangan kabel UTP ada 2 tipe, tipe straight dan tipe cross. Disebut tipe straight soalnya masing masing kabel yang jumlahnya 8 itu berkorespondensi 1-1, langsung.
Sedangkan disebut cross soalnya ada persilangan pada susunan kabelnya. Bingung? OK! Untuk tipe straight itu digunakan buat nyambungin dari client ke hub. Sedangkan untuk tipe cross untuk client langsung ke client (cpu to cpu) ato dari hub ke hub. Kita bahas dulu yang tipe straight
Urutan pin tipe straightTipe ini paling gampang dibuat. Kenapa? Soalnya langsung korespondensinya 1-1. Standar urutannya sih begini (dilihat dari bolongannya konektor, dari kiri ke kanan - lihat foto disamping) : 2 orange - 1 ijo - 2 biru - 1 ijo - 2 coklat . 2 orange disini maksudnya pasangan orange muda sama orange tua, dst. Tapi ga usah ikut standar pewarnaan itu juga sebenarnya tidak masalah. Yang penting urutan kabelnya. Misal ujung sini urutan pin pertamanya orange muda, maka ujung yang lain urutan ping pertamanya juga harus orange muda. jadi antar ujung saling nyambung. Sebenarnya tidak semua pin tersebut digunakan. Yang penting adalah pin nomor 1,2,3 dan 6. Jadi misal yang disambung cuman pin 1,2,3 dan 6 sedangkan pin yang lain tidak dipasang, tidak jadi soal.

Nah waktu mo pasang kamu potong ujung kabelnya, trus susun kabelnya trus ratain pake piso potong yang ada di crimp tool. Kamu ga perlu repot repot harus ngelepasin isolasi pada bagian ujung kabel, soalnya waktu kamu masukin itu kabel ke konektor trus di gencet pake crimp tool, sebenarnya saat itu pin yang ada di konektor nembus mpe dalem kabel. Perhatikan, agar gencetnya yang keras. soalnya klo ga keras kadang itu pin ga tembus ke dalam isolasi kabelnya. Kalo udah trus kamu tes pake lan tester. Masukin ujung ujung kabel ke alatnya, trus nyalain, klo lampu led yang di lan tester nyala semua, dari nomor 1 mpe 8 berarti kamu sukses. Klo ada salah satu yang ga nyala berarti kemungkinan pada pin nomor tersebut ada masalah. Cara paling mudah yaitu kamu gencet lagi pake tang. Kemungkinan pinnya belum tembus. Kalo udah kamu gencet kok masih ga nyambung, coba periksa korespondensinya antar pin udah 1-1 blon. Klo ternyata udah bener dan masih gagal, berarti memang kamu hari ini sedang tidak beruntung.. kesian deh.. hehe.. ulang lagi aja.. okay!

LAN TESTER
LAN TESTER - alat buat ngecek kabelnya nyambungnya bener ato ga. Untuk tipe straight klo bener ntar dari led 1 mpe 8 berkedip.

Berikut adalah foto dari bawah dari ujung kabel UTP yang udah dipasangi konektor dan berhasil dengan baik (urutan pewarnaan pinnya ikut standar):

Contoh konektor RJ45 yang udah dipasang di kabel UTP dan berhasil dengan baik
urutan pin standar

Dan klo yang ini ga standar, coba perhatiin urutan warna pinnya… ga standar banget. tapi tetep aja bisa, yang penting korespondensinya satu satu (khusus tipe straight):

Contoh konektor RJ45 yang udah dipasang di kabel UTP dan berhasil dengan baik - TIDAK STANDAR
urutan pin TIDAK standar

Sekarang Tipe Cross
Untuk tipe cross itu dipake buat nyabungin langsung antar 2 pc, ato yang umumnya buat nyambungin antar hub. (misal karena colokan di hubnya kurang). Cara pasangnya juga sebenarnya gampang. sama seperti tipe straight, pin yang dipake juga sebenarnya cuman 4 pin aja, pin 1-2-3 dan 6. Nah yang beda pas pasangnya. Klo di tipe cross, pin 1 nyambung ke pin 3 ujung yang lain. pin 2 ke 6, pin 3 ke 1 dan pin 6 ke 2. Jelasnya coba deh liat "Gambar 5″. Praktisnya gini, di ujung pertama kamu susun pinnya sesuai standar buat yang tipe "straight" nah di ujung yang laen kamu susun pinnya sesuai standar buat tipe "cross".

masih bingung ? gini deh gampangnya:
ujung pertama:
1: orange muda
2: orange tua
3: ijo muda
4: biru muda
5: biru tua
6: ijo tua
7: coklat muda
8: coklat tua

maka diujung yang lain harus begini:
1: ijo muda
2: ijo tua
3: orange muda
4: biru muda
5: biru tua
6: orange tua
7: coklat muda
8: coklat tua

agak ngerti kan? jadi disini posisi nomor 1,2,3 ma 6 yang dituker.. Nah ntar klo pas di tes pake LAN tester ntar led 1,2,3, ma 6 saling bertukar. Klo tipe straight kan nyalanya urutan, nah klo tipe cross ada yang lompat lompat. Tapi yang pasti kudu nyala semua tiap led dari nomor 1 mpe 8.

Ok deh selamat bikin jaringan. Semoga kamu bisa berhasil waktu pasang konektor di kabelnya.. hehe.. Moga ilmu ini berguna buat kamu, soalnya waktu dulu gue pertama bikin jaringan lucu banget deh, buat ngupas kabelnya gue masih pake cutter, padahal kan udah ada tuh di crimp toolnya. Udah gitu ujung ujungnya tiap kabel aku kelupas lagi pake cutter. padahal yang betul ga usah di kupas atu atu, biarin aja rata, soalnya ntar pas di 'crimp tool' kan itu pin masing masing tembus ke dalem kabelnya.

the problem sound in ubuntu

The problem sound often happened after carrying out the installation ubuntu for example the voice did not go out or the voice was too soft. This more often happened in the installation that was carried out in laptop. Like my experience personal carried out the installation ubuntu in laptop Acer TravelMate 3270. At that time in fact the voice sound did not go completely out. The same thing happened to friends in the campus that also experienced the similar matter. After I the cheque did not have the problem with sound-card I, sound card I HDA Intelligence with chipset Realtek didetect by ubuntu. After seldom thought "Whether possibly his volume or PCM him was not yet activated?" . Please by me saw by using the order of the volume regulation through the terminal that is alsamixer. And evidently quite true the Front and PCM I still 0 Volumenya. To be opened alsamixer the clique of
