Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] An embodiment of the present invention provides a pixel circuit, such as figure 2 As shown, it includes a display unit 10 and a first pre-charging unit 20 .

[0031] The first pre-charging unit 20 is connected to the display unit 10, the N-1th scanning line Scan N-1 and the control line CL, and is used to convert light energy into electrical energy, and scan on the control line CL and the N-1th Under the control of the line Scan N-1, the display unit ...

Abstract

Embodiments of the present invention provide a pixel circuit, a driving method thereof, and a display device, which relate to the field of display technology, and can use light energy to precharge pixels, which improves the excessive load caused by simultaneous input signals of two scanning lines in the prior art Or the problem of mutual interference between scan lines. The pixel circuit includes a display unit and a first pre-charging unit; the first pre-charging unit is connected to the display unit, the N-1th scanning line and the control line, and is used to convert light energy into electrical energy, and Under the control of the control line and the N-1th scanning line, the converted electric energy is used to precharge the display unit; the display unit is also connected to the Nth scanning line and the data line for Under the control of the Nth scan line, the display unit is charged through the data line. Among them, N≥2.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel circuit, a driving method thereof, and a display device. Background technique [0002] Currently, a Liquid Crystal Display (LCD for short) is more and more widely used due to its advantages of low power consumption, miniaturization, thinness, and the like. [0003] The thin film transistor (Thin Film Transistor, TFT for short) in the LCD may have insufficient charging time for the pixels due to the high scanning frequency. In the existing technology, such as figure 1 As shown, precharge (Precharge) is usually used to solve this technical problem, that is, the gate start signal is turned on in advance so that the scanning line Scan outputs the signal in advance (the signal is output from the T1 time period), so that the gate of the TFT is turned on, In this way, the pixels can be charged in advance, so the pixels can be charged to the required potential more qui...
