Organic Light Emitting Diode (OLED) displays offer superior performance and lower costs than Liquid-Crystal Display (LCD) panels. Unfortunately, they also come with several issues including non-uniformity (“Mura”) and image retention or burn-in of images on the display.
Application of IGNIS technology overcomes these issues. By using DRIVE circuits on the panel, we can MEASURE the performance of the OLED and through our proprietary algorithms we COMPENSATE the panel so that there are no visible signs of aging.
Watch a video to see our compensation technology in action.
This automotive prototype panel was temperature stressed at 85° C for more than 1000 hrs and had visible squares burned into the panel. The panel was developed to show the impact of compensation, so a switch was added to the circuit in order to turn the compensation technology on and off. Without IGNIS technology, the differential aging (visible squares) on the panel is quite visible. When the technology is applied, the aging (squares) is no longer visible.
Burn-in from OLED aging continues to be a problem for AMOLED screens used in the latest mobile phone displays. In this video we demonstrate how IGNIS’s proprietary technology can identify and correct the problem of image retention on a Google Pixel 2 device.
The burn-in appears as square in the top right corner of the panel.
This video demonstrates our compensation technology applied at various grey levels and in colour on a refurbished Samsung Galaxy S6.
Using a 20″ AMOLED TV design, we burned the IGNIS logo into the panel that already had some defects. Then, we recorded a video while turning the MaxLife™ image processing on and off. The burn-in is clearly visible, then disappears when MaxLife™ is turned on.
