Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of array circuits of display screens, in particular to an array circuit and a narrow-frame liquid crystal display screen. Background Art
[0002] A liquid crystal display (LCD) consists of an array substrate, an opposing substrate, and a liquid crystal layer located between the two substrates. Thin-film transistors (TFTs) and pixel electrodes are located on the side of the array substrate facing the liquid crystal layer. The array substrate typically includes multiple pixel units, each of which is equipped with a thin-film transistor (TFT).
[0003] The operating principle of a liquid crystal display panel is that the electric field between the opposing substrate and the array substrate causes the liquid crystal to rotate. By adjusting the electric field strength by varying the voltage, the twist and angle of the liquid crystal material can be controlled, thereby controlling the amount of light transmitted in that area, ultimately producing the desired image. The array circuit includes gate lines, data lines, pixel electrodes, and thin-film transistors.
[0004] The left and right borders of existing LCDs cannot be further reduced due to the placement of GIP units, and the gate scan lines are easily coupled with other signal lines, resulting in display horizontal stripes. Utility Model Content

[0044] The existing LCD displays place the GIP units at the left and right borders, which limits the narrow borders of the LCD displays. In addition, the horizontally connected gate lines are easily coupled with other signal lines, resulting in horizontal stripes on the display. Figure 1 , Figure 1 It is a schematic diagram of the GIP unit layout of a liquid crystal display screen in the prior art.
[0045] To solve the above problems, an array circuit and a narrow-frame liquid crystal display are proposed.

By placing the GIP units at the top and bottom frames, the left and right frames can be narrowed; by electrically connecting the gate lines to the pixels in a step-by-step manner, coupling between the gate lines and the signal lines can be avoided, thereby resolving the problem of placing the GIP units at the left and right frames of a liquid crystal display, which limits the narrowness of the frame and easily causes the gate lines to couple with other signal lines, resulting in horizontal stripes on the display.
[0047] Specifically, the pixel unit includes R pixels, G pixels, and B pixels; the R pixels, G pixels, and B pixels in the plurality of pixel units are arranged horizontally in the pixel array.
[0048] Assume that the pixel array size is 4*4, such as Figure 6 and 7 , Figure 6 This is a schematic diagram of the pixel array layout in the first direction of the present invention.

Then, the next GIP unit is electrically connected to the gates of pixels 12, 23, and 34. The next GIP unit is electrically connected to the gates of pixels 11, 22, 33, and 44, and so on, until it is connected to the gate of the last pixel 41.
