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-1 scanning line ScanN-1 and the control line CL, and is used to convert light energy into electrical energy, and connects the control line CL and the N-1 scanning line Under the control of ScanN-1, the converted ele...

Abstract

The embodiment of the invention provides a pixel circuit, a drive method thereof and a display device, and relates to the display technology field. Pixels can be pre-charged by means of luminous energy, and the problem of excessive load caused by signal input by two scan lines simultaneously and the problem of mutual interference between the scan lines are solved. The pixel circuit includes a display unit and a first pre-charge unit. The first pre-charge unit is connected to the display unit, the (N-1) scan line and a control line, and is used for converting luminous energy into electric energy and utilizing the electric energy through conversion to pre-charge the display unit under the control of the control line and the N-1 scan line. The display unit is connected to the N scan line and a data line, and is used for charging the display unit by means of the data line under the control of the N scan line, N being greater than or equal to 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 (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 quickly within the actual...
