LUT-based compensation model for OLED degradation

摘要

A compensation model for blue OLED devices, which is based on an OLED degradation model derived from luminance measurements of OLED devices, has been developed; it reduces degradation effects by monitoring the activity of a set of subpixels and adjusting the driving conditions of the blue subpixels of the display accordingly. To evaluate its performance, the compensation model has been embedded in an OLED display controller model, where its implementation is based on a lookup table. Simulations show that even with a reduced number of monitored subpixels, degradation is effectively reduced.
