A pressure repair device and method

Abstract

The invention discloses a pressure repairing device. The pressure repairing device is used for beating a display panel so as to conduct pressure repairing. The pressure repairing device comprises an impact head, an air pressure gauge, a micrometer and a counter. The impact head is used for beating the display panel. The air pressure gauge is used for monitoring air pressure so that a control unit can be used for controlling the beating air pressure from the impact heat to the display panel. The micrometer is used for controlling the beating spacing distance from the impact head to the display panel. The counter controls the times of beating from the impact head to the display panel through the control unit. The invention further provides a pressure repairing method. The pressure repairing device and method can improve repairing success rate, thereby improving the production efficiency of the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pressure repair device and method. Background technique [0002] With the development of science and technology, thin and light, power-saving information products have flooded our lives, and displays have played a very important role in it. Whether it is a mobile phone, a personal digital assistant or a notebook computer, etc., display devices are required As a platform for man-machine communication. [0003] The display panel of the display device will produce foreign particles (Particles) during the process of liquid crystal cells, such as bright spots, etc., which are defective. Therefore, it is necessary to perform pressure repair on the display panel that produces bright spots. [0004] figure 1 A schematic diagram of a traditional pressure repair device, such as figure 1 As shown, the pressure repairing device uses the impact head 1 to perform pressure repair on a dis...

Problems solved by technology

[0005] The traditional repair method is to use a laser to cut the ITO pixel electrode around the bright point on the TFT substrate 10 surface. However, the disadvantage of this laser repair method is that the repair area will often light up in the dark state after repair, and it cannot be completely dark. If the cutting area is too large, new bright spots will also be generated, resulting in a low success rate of the traditional laser repair method. Using the traditional pressure repair device to conduct multiple tests on display panels of different sizes, the repair success rate is about 20%. %
