A display device and its driving method

Abstract

The invention, which relates to the field of the display technology, provides a display apparatus and a driving method thereof. With the display apparatus, a problem that the drive circuit module outputs a scanning signal due to load changing and thus the voltage is reduced to cause grid voltage reduction can be solved. The display apparatus comprises a plurality of grid lines and at least two drive circuit modules. The at least two drive circuit modules consist of a first drive circuit module and a second drive circuit module; a signal output terminal of the first drive circuit module is connected electrically with first ends of n1 grid lines arranged continuously; the second drive circuit module is connected electrically with second ends of n2 grid lines arranged continuously, an output starting control terminal of the second drive circuit module is connected with the first grid line among the n2 grid lines arranged according a scanning sequence, and a signal output terminal of the second drive circuit module is connected electrically with the rest of n2-1 gird lines among the n2 grid lines. The last m1 gird lines among the n1 grid lines arranged according to the scanning sequence and the top m1 grid lines among the n2 grid lines arranged according to the scanning sequence are same grid lines, wherein the m1 is larger than or equal to 2 and is less than n1 and n2. The technical scheme is suitable for manufacturing a display apparatus.

Problems solved by technology

[0007] Embodiments of the present invention provide a display device and its driving method. When the above driving method is applied to the display device, it can solve the problem that the voltage of the scanning signal output by the gate drive circuit module decreases due to load changes, which in turn causes the voltage of the gate line to decrease. The problem; to further improve the boundary line generated at the junction of the grid lines driven by two adjacent gate drive circuit modules due to the reduction of the grid line voltage when the same gray-scale picture is displayed, which in turn causes the problem of two split screens
