What is an OLED display?
OLED is short for Organic Light Emitting Diode, a device composed of thin carbon-based films placed between two electrodes that creates light with the application of electricity. Unlike other screen technologies, (like LCDs), which require backlighting, OLED displays are emissive devices - they emit light rather than manipulate transmitted external light.
OLEDs provide brighter, crisper colors and contrast on electronic devices and use less power than conventional light-emitting diodes (LEDs) or liquid crystal displays (LCDs) used today. This revolutionary technology is fit for various types of screens, like computer screens, mobile phones, tablets, TVs and more. OLED screens are light, thin, high-resolution and contain individually-lit pixels that make for true blacks and superior color contrast. Since they also consume much less power than LCDs and can be made flexible, it seems OLEDs are the choice of the future.
OLEDs do, however, have several downsides. For starters, they are currently relatively expensive due to high manufacturing costs. They are also quite sensitive to oxygen/water damage and may suffer from burn-in (an image that is displayed for a long time might leave a permanent mark on the screen). It’s important to say that with the extensive work being put into OLED technology, it is indeed improving very rapidly and these weaknesses will probably be dealt with in the future.

Dell's Venue 8 7000 is an Android tablet, released in January 2015 ($400 in the US), based on Intel's 64-bit quad-core Atom architecture (Moorefield) with a 8.4" WQXGA (2560x1600) Super AMOLED display (359 PPI, made by Samsung Display). It is the world's thinnest tablet at 6 mm, and features Intel's RealSense Snapshot Depth Camera.
In December 2014 Fujitsu announced a new tablet, the Arrows Tab F-03G. This large (10.5") tablet is waterproof and dustproof, and it uses the same 10.5" WQXGA (2560x1600) Super AMOLED display used in Samsung's Galaxy Tab S 10.5. Other features include a quad-core 2.3Ghz CPU and a quad-core GPU, 2GB of RAM, 64GB of storage, a 7840 mAh battery and Android 4.4.2. The Arrows Tab F-03G is currently available in Japan only.
OLED tablets - the beginning
The first OLED-display tablet to hit the market was Samsung Galaxy Tab 7.7 back in 2011, that had a 7.7’’ Super AMOLED Plus panel offering 1280X800 resolution. Other specs include Android v3.2, Dual-core 1.4Ghz processor, HSPA+ radio, 16GB to 64GB internal storage and a microSD slot, Wi-Fi, GPS and two cameras (3MP and 2MP).The Toshiba Excite 7.7 was a slim and light tablet with the same 7.7’’ 1280X800 Super AMOLED Plus display and a quad-core Tegra 3 CPU.
