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] In the technical solution provided by the embodiment of the present application, the timing controller (TimingController, TCON) is used 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 for the GOA drive unit. The difference in brightness displayed by each row solves 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 of t...

Abstract

The invention discloses a driving method and apparatus of a gate driver on array (GOA) circuit, a sequential controller, and a display device, for compensating brightness differences of rows where panel cross striations are disposed and preventing the panel cross striations visually generated in human eyes. The driving method of the GOA circuit comprises the following steps: determining a bright-dark period of the panel cross striations of a display panel; and according to the bright-dark period of the panel cross striations, performing periodical data signal compensation on the rows where the panel cross striations are disposed.

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 an array substrate row driving (Gated driver On Array, GOA) circuit. 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 ...
