A New Low-power Pixel Circuit for OLEDoS Microdisplay

In order to solve the problem of high bandwidth data volume and low power consumption of OLEDoS microdisplay panels, this paper proposes a new type of digital low-power pixel circuit. The driving circuit includes a plurality of pixel driving units, which can store multi-pixel bit information at one time, thereby reducing the amount of data read operation. Compared with the traditional digital pixel circuit, the proposed circuit can skip the grayscale data writing process when the picture is still or the rate of change is low, thus reducing the data flow and power consumption.
