Abstract
Provided is a pixel driving circuit capable of reducing power consumed for pixel driving by reducing the number of times a capacitor is charged. The pixel driving circuit includes: a video memory configured to store video data related to driving of a plurality of light-emitting devices; a plurality of sub-pixel driving units, respectively corresponding to the plurality of light-emitting devices, configured to supply power to the plurality of light-emitting devices according to the video data stored in the video memory, each of the plurality of sub-pixel driving units having a capacitor unit for charging power required for driving each of the plurality of light-emitting devices; a charge control memory configured to store data related to charging of the capacitor unit; and a charge controller configured to control whether the capacitor unit is charged according to charge control data stored in the charge control memory.
