Abstract:
A pixel driving circuit, a display panel and a display device are provided. The pixel driving circuit includes a first control module electrically connected to a first node. The first control module receives the first control signal and the first power voltage. The first control module is used to write the first power voltage into the first node under the control of the first control signal when the voltage of the first control signal is higher than the first predetermined threshold voltage. Because the first power voltage is written into the first node to control the lighting device to generate light when the first control signal is higher than the first predetermined threshold voltage, this could prevent the lighting device from generating the color shift. In this way, the requirement for the chip performance is comparatively low and thus the manufacturing cost is reduced.
