Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] figure 2 It is a schematic structural diagram of a liquid crystal display device according to an embodiment of the present invention. refer to figure 2 , the liquid crystal display device may include: a liquid crystal panel 1 for displaying images, a source driver 2 , a gate driver 3 , a timing controller 4 and a backlight module 5 . The timing controller 4 sends the gray scale data signal, the polarity inversion signal POL, and the latch signal TP to the source driver 2, and sends the frame start signal STV, the clock signal CPV, and the output timing signal OE to the gate driver 3 , the source driver and the gate driver respectively output row and column signals to control the liquid crystal display panel 1 to display.

Abstract

The invention provides a pixel unit and a liquid crystal display device and belongs to the field of liquid crystal display. The pixel unit comprises multiple pixels, multiple grid lines and multiple data lines, wherein the multiple pixels are arrayed in a matrix mode, each pixel comprises a red sub pixel, a green sub pixel, a blue sub pixel, a white sub pixel and a yellow sub pixel; the multiple grid lines are used for receiving scanning signals according to a time sequence, and each grid line is connected with five rows of sub pixels; the data lines are used for receiving data signals, every 5 data lines are connected with 1 column of sub pixels, the first data line is connected with the 5k plus 1 sub pixel of the column of sub pixels, the second data line is connected with the 5k plus 2 sub pixel of the column of sub pixels, the third data line is connected with the 5k plus 3 sub pixel of the column of sub pixels, the fourth data line is connected with the 5k plus 4 sub pixel of the column of sub pixels, the fifth data line is connected with the 5k plus 5 sub pixel of the column of sub pixels, k equals to 0,1,2 ellipsis, K minus 1, and K is one fifth of the total rows of sub pixels. According to the invention, the image quality is effectively improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a pixel unit and a liquid crystal display device. Background technique [0002] figure 1 It is a structural schematic diagram of a liquid crystal display device in the prior art. refer to figure 1 , the liquid crystal display device includes: a liquid crystal panel for displaying images, a source driver (Source Driver), a gate driver (Gate Driver), a timing controller (Tcon) and a backlight module. The liquid crystal panel includes: a plurality of pixels arranged in a matrix, and each pixel includes three sub-pixels of red (R), green (G) and blue (B); a plurality of gate lines for receiving and scanning in sequence signal, wherein each gate line is connected to one row of sub-pixels; multiple data lines are used to receive data signals, wherein each data line is connected to one column of sub-pixels. [0003] The gate driver is coupled to the liquid crystal panel, and is...
