And this operation mode will cause a data writing time (t2) between the gate pulses output by the two adjacent gate lines of the sub-pixel to overlap, so when the data is written, the adjacent gate lines It will affect the voltage of the sub-pixel through the parasitic capacitance between the sub-pixel and the gate line, which will make the display screen abnormal

Embodiment Construction

[0052] Please refer to Figure 3A, which shows the first embodiment of the liquid crystal display panel of the present invention. The present invention is a liquid crystal display panel with three-way gate pixel arrangement, including a data driver 520, a gate drive unit 510 and a pixel array. Wherein, the data driver 520 includes m data lines (D1˜Dm); the gate driving unit 510 is connected to 3n gate lines.

[0053] Furthermore, the driving method of the data lines is driven by column inversion, that is, the driving polarities of two adjacent data lines are opposite at the same time, so the first data line D1 is positive. , the second data line D2 is negative, and so on. The liquid crystal display panel will receive a common voltage level (Vcom). When the voltage value on the data line is greater than the common voltage level, it is positive (+), and when the voltage value on the data line is less than the common voltage level, it is negative. sex(-).

Abstract

The invention provides a liquid crystal display panel, which comprises a plurality of basic arrangement units, wherein each basic arrangement comprises six lines, wherein the first line includes four first color sub-pixels, the second line includes four second color sub-pixels, the third line includes four third color sub-pixels, the fourth line includes four fourth color sub-pixels, the fifth line includes four fifth color sub-pixels and the sixth line includes four sixth color sub-pixels. The invention has the advantages that: by changing the arrangement way of a pixel array and using a line reversal drive way the stability of common voltage electrical level is maintained. In addition, grid pulses output by an upper grid line and a lower grid line adjacent to each other of the sub-pixelare not overlapped through the connection treatment of a wiring area so as to maintain a normal display picture.

Description

technical field [0001] The invention relates to a liquid crystal display panel, in particular to a liquid crystal display panel integrating a grid driving circuit. Background technique [0002] Generally speaking, a liquid crystal display panel includes a plurality of gate lines connected to a gate driver, and a plurality of data lines connected to a data driver, or called a source driver. (source driver). In order to effectively reduce the number of data lines and reduce manufacturing costs. Therefore, a liquid crystal display panel with tri-gate pixel arrangement is proposed. That is to say, the red, green, blue (R, G, B) sub-pixels (sub-pixels) in each pixel are arranged along the direction of the data line, so that a complete display screen needs 3 times the original grid. The number of drivers, but can be matched with the integration of the gate driver on the LCD panel, so the overall production cost can be reduced. [0003] Please refer to Figure 1A , which is a s...
