Drive load compensation unit, method, module and display device

Abstract

The invention provides a driving load compensation unit, a method, a module and a display device. The drive load compensation unit includes a load compensation control subunit and a resistance-capacitance load subunit; the resistance-capacitance load subunit includes N switch modules and N resistance-capacitance load modules; N is an integer greater than 1; the nth switch module The first end of the first end is connected to the first end of the n-1 resistance-capacitance load module, and the second end of the n-th switch module is connected to the second end of the n-th resistance-capacitance load module; n is greater than 1 and less than or equal to An integer of N; the load compensation control subunit generates a first load compensation control signal and an nth load compensation control signal; the nth switch module is used to control on or off under the control of the nth load compensation control signal A connection between the first end of the nth switch module and the second end of the nth switch module. The invention solves the problem that the driving current of the pixels in the main and auxiliary display areas is not uniform, resulting in brightness differences.

Description

technical field [0001] The invention relates to the technical field of display driving, in particular to a driving load compensation unit, method, module and display device. Background technique [0002] Figure 1A It is a schematic diagram of a display panel in a full-screen borderless form. The display panel is as follows: a main display area 101 for conventional display; a first sub-display area 102 for special display; a second sub-display area 103 for special display; And, avoid the non-display area 104 of the mobile phone camera and the earpiece. In order to avoid the camera and earpiece of the mobile phone, there will be a grooved area with a certain depth and width on the top of the display panel, which divides the top display area into two sub-display areas. Since the number of sub-pixel units per row in each sub-display area is less than the number of sub-pixel units per row in the main display area, the load of the main gate drive unit corresponding to the main d...

Problems solved by technology

[0004] The main purpose of the present invention is to provide a driving load compensation unit, method, module and display device, which can solve the problem of the main and auxiliary display areas caused by inconsistent charging time when each sub-pixel unit is given the same gray scale voltage in the prior art. The pixel drive current is not uniform, resulting in the problem of brightness differences
