Abstract

The invention discloses a GIP (Gate In Panel) type LCD (Liquid Crystal Display) device, and is used for solving the problems that a vertical mura can be easily generated when a GIP technology and a Dual gate technology are used at the same time, and thus the display of the LCD device is bad. The GIP type LCD device is characterized in that a clock generation unit is used for respectively providing K scanning clock signals to a first driving subunit and a second driving subunit according to scanning sequences, and thus driving signals can be provided for grid lines in odd number lines / even number lines by the first driving subunit / the second driving subunit; in a first scanning sequence, the time sequence for scanning the scanning clock signals of the grid line in a 2Nth line is delayed than the time sequence for scanning the scanning clock signals of the grid lines in a (2N-1)th line by 1 / 2K period; in a second scanning sequence, the time sequence for scanning the scanning clock signals of the grid lines of the grid lines in the (2N-1)th line is delayed than the time sequence for scanning the scanning clock signals of the grid lines in the 2Nth line by 1 / 2K period; N is a natural number, K=2m, and m is a natural number.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a GIP type liquid crystal display device. Background technique [0002] The liquid crystal display device includes a liquid crystal panel equipped with a plurality of gate lines and a plurality of data lines, a gate driving unit outputting gate signals to the gate lines, and a source driving unit outputting data signals to the data lines. With the continuous development of technology, various cost-reducing driving technologies are applied to liquid crystal display products, including Dual gate technology and the technology of making the gate driver on the panel (Gate In Panel, GIP). Dual gate technology is a driving technology that reduces the number of data lines of the LCD panel by half and doubles the number of gate lines. It halves the number of source driver ICs and doubles the number of gate driver ICs, because the unit price of gate driver ICs It is cheaper than the ...
