Problems solved by technology
When the number of unit screens in a mother glass is small, the marking work of the panel identification is relatively simple and occupies less production capacity of the production line; but when the number of unit screens on a mother glass is large, the marking of the panel identification The work will be more cumbersome and take up more production line capacity
In particular, the size of the unit screens made by each panel generation line is getting smaller and smaller. There are hundreds of unit screens on the substrate on a mother glass, and the marking work of the panel logo becomes more difficult.
Sometimes, for the consideration of production line capacity, the panel marking is no longer carried out, so that the problems in the subsequent production process cannot be traced back to the previous process, which greatly reduces the efficiency of the production line
On the other hand, the surrounding area of small-sized display screens is getting smaller and smaller, and the panel logo itself will occupy a certain amount of space. It is necessary to explore the marking method of the panel logo of small-sized display screens

[0042] For the preparation of array substrates and color filter substrates, various thin film patterns are prepared on large-area mother glass (base substrate), and then cut into unit display panels. With the gradual development of liquid crystal panel preparation technology, the mother glass used to manufacture liquid crystal panels is getting larger and larger, therefore, multiple unit display panels can be cut out of one liquid crystal panel mother plate. For example, the substrate size of the highest stage of the 5th generation line is 1200mm×1300mm, while the substrate size of the 8th generation line can reach 2160mm×2460mm. When preparing various thin film patterns on such a large substrate, it is impossible to perform one exposure on the entire substrate in the patterned exposure process, but to expose in batches in several areas on the same substrate according to the conditions of the exposure process . Here, the area that can be covered by one exposure on the substra...

A liquid crystal display panel, a manufacturing method thereof, and a liquid crystal display panel motherboard. According to an embodiment of the present invention, on the one hand, by designing the reticle of the array substrate of the liquid crystal screen, logo patterns are formed on different unit display panel areas in the same exposure area of the array substrate motherboard, and the unit display panels exposed in the same batch On the other hand, through the arrangement of the color filters in the unit display panel area of the color filter substrate motherboard, the unit display panels exposed in different batches are distinguished, so as to realize all the display panels in the same motherboard glass Markup of the cell display panel. According to the embodiments of the present invention, the problem that the marking process of the current panel logo affects the production line capacity can be solved, and the problem that the panel logo occupies a relatively large space around the display screen can be solved.
Description
technical field [0001] Embodiments of the present invention relate to a liquid crystal display panel, a manufacturing method thereof, and a mother board of a liquid crystal display panel. Background technique [0002] In the field of display technology, liquid crystal display panels are widely used in modern digital information equipment due to their advantages of small size, low power consumption, no radiation, and high resolution. [0003] For panel manufacturers, the more unit displays cut out from the same mother glass, the more profitable the production line will be. In order to distinguish each unit display screen, a panel ID (Panel ID) will be made on each unit display screen during the production process. Since the panel identification of each unit screen is different, a laser pointer is used to mark each unit screen in turn on the production line. When the number of unit screens in a mother glass is small, the marking work of the panel identification is relatively...
