Embodiment Construction

[0033] Embodiments of the present application provide a driving method, device, timing controller, and display device for a GOA circuit, which are used to compensate the brightness difference of the row where the horizontal stripes of the panel are located, and avoid the horizontal stripes on the panel perceived by human eyes.

[0034] The technical solution provided by the embodiment of the present application uses a timing controller (Timing Controller, TCON) to adjust the differential output of the data signal of each row of the panel in the GOA cycle, and the differential output of the same row of each frame (frame), to compensate the GOA drive unit The brightness difference displayed by each line in the display can solve the horizontal water mark phenomenon in human vision.

[0035] The technical solutions provided by the embodiments of the present application will be introduced below in conjunction with the accompanying drawings.

[0036] see figure 1 , the embodiment o...

Abstract

The present disclosure provides a method and a device for driving a GOA circuit, a time controller and a display device. The method includes steps of: determining a bright-dark period for striped patterns on a display panel; and compensating for data signals at rows where the striped patterns are located periodically in accordance with the bright-dark period.

Description

technical field [0001] The present application relates to the technical field of liquid crystal display, and in particular to a driving method, device, timing controller, and display device for a Gate driver OnArray (GOA) circuit of an array substrate. Background technique [0002] In the thin film transistor liquid crystal display (TFT-LCD) GOA product, taking the structure of 6 clock (clk) signals as an example, due to the impedance difference between the clk signal lines, the degree of opening of the gates of the two lines is different. As a result, horizontal water streaks (abbreviated as horizontal streaks) of a display panel (panel) with a period of 6 lines are defective. Contents of the invention [0003] Embodiments of the present application provide a driving method, device, timing controller, and display device for a GOA circuit, which are used to compensate the brightness difference of the row where the horizontal stripes of the panel are located, and avoid the ...
