Manufacturing method of liquid crystal display panel with narrow bezel

Abstract

The invention provides a manufacturing method of a liquid crystal display panel with a narrow bezel. A plurality of panel units arranged in an array mode are manufactured on the liquid crystal display master panel, a group of testing points are arranged corresponding to the panel units, a group of thin film transistors and a control signal point are arranged corresponding to each panel unit, and the testing points and the control signal points are all arranged on the outer side of the panel unit array. When panel unit testing is conducted, one corresponding group of thin film transistors are controlled to be connected by transmitting a control signal to the control signal point corresponding to a to-be-tested panel unit, a testing signal is transmitted to one corresponding group of testing points, control signals are transmitted to the other control signal points to control the corresponding groups of thin film transistors to be cut off so that it can be ensured that each panel unit can be tested independently, the bezel size of the liquid crystal display panel manufactured after a cutting process is reduced, and the narrow bezel of the liquid crystal display panel is easily achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a liquid crystal display panel with a narrow frame. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module (Backlight Module). The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires between the two glass substrates. The...

AI Technical Summary

Problems solved by technology

The manufacture method of existing liquid crystal display panel comprises the steps: step 1, such as figure 1 As shown, a liquid crystal display motherboard 1 is provided, and a plurality of panel units 2 arranged in an array are fabricated on the liquid crystal display motherboard 1; each panel unit 2 includes a display area (Active Area, AA) 201, and a plurality of test points 202 located above the display area 201 and electrically connected to the display area 201; step 2, such as figure 2 As shown, the liquid crystal display motherboard 1 is cut along two adjacent columns of panel units 2 and two adjacent rows of panel units 2 to obtain a plurality of liquid crystal display panels 203; There are a plurality of test points 202 electrically connected to the display area 201. As we all know, the number of test points 202 in the liquid crystal display panel 203 is large and the size is large, so the test points 202 occupy a large space in the liquid crystal display panel 203 , eventually resulting in a larger upper frame size of the liquid crystal display panel 203, which is not conducive to realizing a narrow frame of the liquid crystal display panel 203
