The OLED display has been known to have excellent display characteristics such as high response speed, wide viewing angle and color rendering capabilities. However, OLED devices require sustained efforts to improve the OLED lifetime due to a characteristic that the luminance decreases according to elapsed time. In this paper, we proposed hierarchical logo detection and brightness control method to prevent image sticking on OLED TV. We have experimented with this method in FPGA and We prove that the proposed algorithm can increase the lifetime of OLED TV.
