Abstract:
The present invention provides a pixel driving circuit, a display apparatus and a terminal. The pixel driving circuit includes: a light-emitting device, an enabling unit, a first transistor and a second transistor. When the light-emitting device illuminates, saturated current passing through the light-emitting device is relevant to the power voltage and the grayscale data voltage. Through embodiment of the present invention, saturated current passing through the driving transistor is relevant to the power voltage and the grayscale data voltage. Furthermore, both the power voltage and the grayscale data voltage are fixed values, that is, current passing through the light-emitting device is guaranteed to the constant. Therefore, current passing through the light-emitting device is no longer affected by the threshold voltage of the driving transistor and non-uniform pixel color could be avoided, accordingly, image uniformity of display with light-emitting device (e.g., OLED) raises, and so does display quality.

Claim (Index 10):
