Methodology Research & ASIC Design for OLED-On-Silicon Pixel Circuit
This paper proposes a time grayscale control method associated with source current mirror using binary latch scheme to take place conventional structure which uses capacitance with MOSFET. The time grayscale control method based on the characteristics that the Luminance can stay for a while in human eyes controls the time period of pixel work to make different gray scales, and it solves the division limitation of magnitude control. The data we used has 2 states, high or tow, just make the OLED on or off. In the pixel select period, the data is locked in the binary latch, and during the unselect period, the data in the latch will still make the OLED work as the situation just in the select period. Here we use high impedance , high precise constant current source mirror structure to drive the OLED, which can solve the problems including delay of the capacitance and nonuniform over display in the drive circuit of AM-OLED in existence.
