Problems solved by technology

The vacuum bonding process is very important for liquid crystal display products. If the position of the array mother board and the color film mother board are offset during the vacuum bonding process, it will cause light leakage and contrast drop of the liquid crystal display.
[0008] After the array motherboard and the color film motherboard are vacuum bonded, the array motherboard and the color film motherboard are only connected by the uncured sealant, and after the liquid crystal display motherboard is vacuum bonded, it is transferred to the UV curing device for the sealant. During the transfer process, as the robot arm accelerates or decelerates, the LCD motherboard is in direct contact with the robot arm, so the motherboard on the side that is in direct contact with the robot arm will accelerate or decelerate along with the robot arm, while the side away from the robot arm The motherboard is affected by inertia, and the motherboard on the side that is in direct contact with the robot arm will inevitably have some misalignment, which will cause a series of problems such as light leakage and liquid crystal leakage.
[0009] Therefore, how to solve the position shift caused by the liquid crystal display motherboard after lamination and before the sealing glue is cured, and the resulting light leakage, liquid crystal leakage and other problems are the technologies that need to be solved urgently by those skilled in the art. question

Abstract

The invention provides a liquid crystal display motherboard which is provided with array motherboards and color film motherboards which are oppositely arranged. The liquid crystal display motherboard is characterized in that the liquid crystal display motherboard comprises at least a first area and second areas surrounding the first area. Each first area comprises at least one display single chip, and the array motherboard part at the edge position of each display single chip and the color film motherboard part at the edge position of each display single chip are fixed in a sealed mode through first frame sealing adhesive. A liquid crystal layer is arranged in the sealed space formed by the first frame sealing adhesive, the array motherboard part of each display single chip and the color film motherboard part of each display single chip. At least one second frame sealing adhesive of a closed shape is included in the second area. The second frame sealing adhesive seal and fix the array motherboard part of a closed shape and the color film motherboard part of a closed shape. By means of the liquid crystal display motherboard, the problems of light leakage and liquid crystal leakage generated in the moving process of the attached liquid crystal display motherboards are solved.
