IGNIS MaxLife™ AMOLED TV Driver

Nov 28 2011

IGNIS has developed and verified the second generation of its MaxLife™ driver IC for AMOLED TVs, monitors and tablets. Key features of this technology include: Corrects for aging and non-uniformity in both the backplane and the OLED. Resolves all image quality issues such as Mura, image sticking, and colour shift. Compatible with all backplanes (amorphous silicon, polysilicon, and oxide TFT), and all types of OLED (white with colour filter, evaporated, printed, etc.). Supports high resolutions, high frame rates, and 3D. With polysilicon or oxide TFTs backplanes, where uniformity is an issue, the yield can be improved from a few percent to an acceptable production level. With amorphous silicon backplanes, where aging and speed are an issue, it enables stable high-frame-rate AMOLED televisions.

IGNIS has developed technologies for >300ppi AMOLED display

Nov 28 2011

IGNIS has developed technologies to push the conventional manufacturing techniques to >300 pixels per inch (ppi) AMOLED with true RGB pixels. Also, it has developed pixel circuit and driving scheme to compensate for the non-uniformity and enhance the lifetime of such a high-ppi display. These technologies can make AMOLED displays with similar resolution as IPS displays but with much better colour quality, higher contrast ratio, and wider viewing angle.

IGNIS has developed a multi-functional display

The major issue with AMOLED is the reflectivity which mandates the use of circular polarizer (reducing the OLED efficiency by 57%). IGNIS has developed a technique that not only removes the need for polarizer but also, the display acts as power scavenging device, touch screen, and self-calibration unit for non-uniformity/aging. Also, the manufacturing steps are not altered which results in the same yield and cost as normal AMOLED display with no-touch capabilities. IGNIS believes that this is a significant move toward adapting AMOLED display for tablet computers.

MaxLife™ Hysteresis Videos on YouTube

Jan 03 2011

One of the problems with some AMOLED backplanes is short-term image sticking. If a user puts an image on the display and leaves it on for a minute or so, then tries to change the image, the original image will be “stuck” for several seconds. This is due to a hysteresis effect in the TFTs (thin-film transistors). We’ve made some videos of an AMOLED display with MaxLife™ technology, at various temperatures, showing no hysteresis effect.
