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 6):
The circuit according to  claim 5 , wherein the second enabling signal (EM[N]) is at a low level, the second scanning signal (Scan[N\u2212 1 ]) and the first scanning signal (Scan[N]) are at a high level, in the meantime, the fourth transistor and the seventh transistor are in a conductive state, the fifth transistor and the sixth transistor are in a turn-off state and the storage capacitor is in a remaining state; a source voltage of third transistor is V dd  and a gate voltage of it is equal to the voltage of negative electrode in storage capacitor, that is, the difference between the grayscale data voltage V data  and threshold voltage V th  of the third transistor, thus, a gate-source voltage difference of the third transistor could be expressed as \u201cV dd \u2212V data +V th \u201d and the gate-source voltage difference is used to drive light-emitting device to emit light.
