Abstract
A pixel driving circuit for a display device includes a clock generator configured to generate clock signals with different time periods for different locations of bit values of the image data, an array of a plurality of pixels, each pixel including a light-emitting element, and an in-pixel memory configured to store image data comprising a set of bit values from a most significant bit (MSB) to a least significant bit (LSB), and a controller configured to read the set of bit values of the image data in an order, starting from the LSB bit to the MSB, to generate pulse width modulation (PWM) signals.
