Luminance uniformity compensation for OLED panels based on FPGA

Aiming at the problem of luminance uniformity for organic lighting-emitting diode （OLED） panels, a new brightness calculating method based on bilinear interpolation is proposed. The irradiance time of each pixel reaching the same lumi- nance is figured out by Matlab. Adopting the 64×32-pixel, single color and passive matrix OLED panel as adjusting luminance uniformity panel, a new circuit compensating scheme based on FPGA is designed. VH L is used to make each pixel＇s irradiance time in one flame period written in program. The irradiance brightness is controlled by changing its irradiance time, and finally, luminance compensation of the panel is realized. The simulation result indicates that the design is reasonable.
