OLED display driver

Amulet Technologies has released a new universal TFT/OLED display driver, the GEMexpress. The new driver is highly-integrated (six-layer PCBA) measuring 1.5"x3.0" and includes the display controller, a touch-panel decoder, and ARM7 processor and Amulet's Graphical-OS-In-Silicon which manages the user-interface for the display.  

Amulet say that this new display driver can save a lot of time because it can interface to 'virtually any display type'. More information over at their site.

4D Systems have recently released a new and improved range of custom graphics processors and display modules:

• The GOLDELOX-GFX2 (enhanced GOLDELOX-GFX): an embedded 4DGL graphics controller. The chip is designed to interface with many popular OLED and LCD display panels.
• New PMOLED modules: The modules are compact and cost effective, with an embedded GOLDELOX-GFX2 graphics processor that delivers ‘stand-alone’ functionality to any project. Powerful graphics, text, image, animation and countless more features are built inside the GOLDELOX-GFX2 chip.
• The GOLDELOX-SGC(8-bit) and the PICASO-SGC(16-bit): intelligent Serial Graphics Controllers designed to interface with many popular color OLED and LCD display panels.
• Smart Serial Display Modules: from a tiny 0.96" OLED module all the way up to 3.2" TFT to suit most small to medium size graphics user interface applications.

ST Microelectronics announced a "key design win" for its power management ICs for AMOLED displays from a leading manufacturer in Korea (which is probably Samsung or LG).

AnalogicTech says it will start making drivers for small AMOLEDs. They claim that they have an innovative power supply waiting in the wings. "An AMOLED needs a positive supply and a negative supply. These need a positive boost converter and a negative boost converter," CEO Richard Williams said. "That's two coils but we are privately sampling a PSU that independently regulates the plus and minus rails from a single coil with a measured efficiency comparable with dual converters."

Gamma correction - this time to compensate for the different characteristics of red, green and blue OLED materials, is another target.

Solomon Systech announces a new OLED driver, the SSD1306. It's aimed for small displays- up to 128x64 resolution. The driver has three capacitors and a built in charge pump, so it can support voltage supply of 3.3V to 4.2V.

Novaled, Fraunhofer IPMS and Optrex Europe developed a new, unique PMOLED driver. They have implemented an innovative MLA scheme called SELA (Summed Equiline Addressing). Basically, instead of driving using a single-line addressing scheme, the SELA allows parallel driving of multiple rows, thus preventing high current amplitudes.

Basically this means that we get higher lifetime, better resolution and better efficiency in the OLED display. The driver is specified for operations between -40°C and +125°C, exhibits an OLED drive voltage up to 25 V, and a column source current up to 2 mA. In particular the latter can currently not be fulfilled by any commercial available PM OLED driver.
