Abstract:
A pixel driving circuit includes a pixel unit including a blue sub-pixel connected to a data line to receive a data voltage, and a limit circuit connected between the data line and a reference voltage line configured to transfer a fixed DC voltage, the limit circuit being configured to limit the received data voltage when the received data voltage exceeds a voltage threshold.
