SinoWealth reports AMOLED driver IC design wins

SinoWealth, an IC developer from Shanghai, started to develop AMOLED drivers last year, and thec ompany now reports that they supplied AMOLED drivers to EverDisplay's first AMOLED panels.

inoWealth also announced that it received orders for more AMOLED driver ICs in China. As the only AMOLED driver maker in China, the company sees rapid market growth in that segment. The company also reports that their PMOLED driver business is maintaining a steady growth.

Solomon Systech announces a high-brightness PMOLED driver

Solomon Systech announced a new PMOLED driver, the SSD1360, that supports super high brightness (up to 600 cd/m2) OLEDs. This character display driver can handle 2-line displays (each with 16 to 24 characters) or a dot display of 120 X 16.

The SSD1360 supports ASCII, English, European and Japanese characters with three built-in ROMs. The driver supports I2C (up to 400kbit/s) and also 4/8-bit parallel and serial interfaces.

Solomon Systech and Visionox developed a qHD AMOLED driver IC

Solomon Systech and Visionox announced that they jointly developed a new qHD (960x540) AMOLED driver IC, which they say is the first one developed in China. The driver passed verification using a 4.6" WVGA full-color AMOLED (probably made by Visionox). The companies are now working to develop a driver with a higher resolution.

This project was funded by China's Electronics Information Industry Development Fund under the Ministry of Industry and Information Technology.

MagnaChip launches a new WXGA AMOLED driver

MagnaChip launched a new WXGA (1280x768) AMOLED driver IC (model EA8061) - targeted for smartphones. MagnaChip is already mass producing the EA8061 and is delivering it to a "major Korean electronics manufacturer" (probably Samsung) for use in selected Android-based smartphones this year.

The EA8061 supports high-definition video based on RGB stripes and features MIPI DSI interface, Content Adaptive Brightness Control (CABC), Automatic Current Limit (ACL) and Multi Power Saving (MPS).

Ignis Innovation at SID 2012

As I already said before, Ignis Innovation's SID booth was one of the conference highlights for me. Their technology is very impressive and hopefully will enable cheaper non-LTPS AMOLED production.






In their booth, Ignis were showing 3.5" and 20" AMOLED panels that use the company's a-Si backplane compensation technology. The panels were made by RiTdisplay. Ignis and RiTdisplay have been showing these displays back in 2011. Originally they were supposed to be released towards the end of 2011, but this never happened. During SID Ignis announced that now the plan is to release these by the end of 2012. According to Ignis the 3.5" AMOLED will be cheaper than the LTPS-based competition (i.e. Samsung made panels). You can read more about these panels and RiTdisplay's plans at my RiTdisplay-at-SID-2012 post.

Ignis announces MaxLife Gen 2 AMOLED Driver IC

Ignis Innovation announced today that they developed and verified the second generation of the MaxLife driver IC - suitable for OLED TVs, monitors and tablets. Ignis wouldn't reveal the changes since Gen 1 - so it may be that the real issue here is support for larger displays.

3.5-inch a-Si AMOLED prototype

The MaxLife driver enables AMOLED displays on a-Si, LTPS and Oxide-TFT backplanes. For LTPS and Oxide-TFTs, it offers better yields. For a-Si backplanes, it enables stable and high frame-rate displays.

STMicroelectronics announce a new miniature AMOLED power supply chip

STMicroelectronics announced the STOD13AS - a new miniature AMOLED power supply chip. The new chip is produced using ST's innovative Silicon On Insulator (SOI) process technology, which ensures outstanding energy efficiency and results in longer battery life. The chip offers high immunity to cellphone-communication noise - and thus minimizes flicker on the display.

ST explains that the new chip is better than the predecessor (the ST0D03A) because it integrates the step-up and inverting DC/DC converters needed to generate the positive and negative supplies on the same chip. It also features increased display-driving capability as well as additional short-circuit and overload protection modes to maximize ruggedness and reliability. When the display is not used, the new chip can be completely turned off which saves more power, and it also features pulse-skipping operation that optimizes efficiency when the display is consuming minimal power.
