Abstract
A display device includes a plurality of pixels, the pixel circuit comprising a PWM driving circuit and a PAM driving circuit, wherein the image data comprising a MSB, at least one middle bit, and a LSB, a processor configured to determine whether a single bit value of the MSB of the image data is '0' or “1”, select the PAM driving circuit or the PWM driving circuit based on the MSB the image data, and generate a driving method selection signal to select one of the PAM driving circuit or the PWM driving circuit based on a selection result, wherein, when the MSB of the image data is “1” the PAM driving circuit is selected to express the image data with the MSB being “1”, and when the MSB is “O” the PWM driving circuit is selected to express the image data with the MSB being “0”.
