Embodiment 1

[0050] image 3 It is a schematic flow chart of the driving method of the display panel in this embodiment, as image 3 As shown, this embodiment includes:

[0051] Step 101: Obtain brightness information of a preset area when a test picture is displayed;

[0052] Wherein, the test picture is a solid color picture, specifically, the gray scale value of the test picture may be 127. The preset area can include one or more rows of pixels, and the picture information of the test picture can be collected by a data collection device such as a high-definition camera, and the collected picture information can be processed to obtain the brightness information of each area.

[0053] Step 102: Modulate the gate drive signal of the preset area according to the acquired brightness information;

[0054] Specifically, the data acquisition device can send the brightness information of the area to a data processor, such as TCON (timer / counter control register) or SOC (system-on-chip), and t...

Embodiment 2

[0059] This embodiment provides a driving circuit for a display panel, such as Figure 4 As shown, this embodiment includes:

[0060] A processing module, configured to obtain brightness information of a preset area when displaying a test picture;

[0061] a modulation module, configured to modulate the gate drive signal of the preset area according to the acquired brightness information;

[0062] The output module is used for inputting the modulated gate driving signal into the pixels in the preset area.

[0063] Further, the processing module includes:

[0064] A collection unit, configured to collect the picture information of the test picture through a data collection device;

[0065] The calculation unit is used to process the collected picture information to obtain the brightness information of the preset area.

[0066] Further, the modulation module includes:

[0067] The search unit is used to determine the waveform modulation signal corresponding to the gate driv...

Embodiment 3

[0079] An embodiment of the present invention also provides a display device, including the above-mentioned drive circuit for a display panel. Wherein, the structure and working principle of the driving circuit of the display panel are the same as those of the above-mentioned embodiments, and will not be repeated here. In addition, the structure of other parts of the display device can refer to the prior art, which will not be described in detail herein. The display device may be a product or component with any display function such as a liquid crystal panel, electronic paper, liquid crystal TV, liquid crystal display, digital photo frame, mobile phone, and tablet computer.

Abstract

The invention provides a drive method and circuit of a display panel and a display device and belongs to the field of display technologies. The drive method of the display panel includes the steps that when a test picture is displayed, brightness information of a preset region is obtained; according to the obtained brightness information, a gate drive signal of the preset region is modulated; a modulated gate drive signal is input into pixels of the preset region. According to the technical scheme, the problem that transverse stripes occur when a pure color picture is displayed on the display panel is solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving method, a driving circuit and a display device of a display panel. Background technique [0002] At present, in the field of display, the application of flat-panel display splicing walls is becoming more and more extensive. Along with the application of large splicing walls, panel manufacturers are unremittingly pursuing the extremely narrow seam of splicing products. At present, the seam has entered the era of less than 4mm. Such as figure 1 As shown, the existing display panel used for splicing adopts the design of X printed circuit board 1+Y printed circuit board 2, wherein 3 is an effective display area. As the seam shrinks gradually, the frame of the display panel becomes narrower, and the area left for wiring in the fan-shaped area becomes narrower and narrower, which will cause the wiring resistance in different areas of the display panel to mismatch, a...
