Liquid crystal panel and manufacturing method thereof

Abstract

The invention discloses a liquid crystal panel. The panel comprises a TFT substrate, a CF substrate disposed on the TFT substrate, a liquid crystal filled between the TFT substrate and the CF substrate and a first polarizer attached to the outer surface of the CF substrate, at least one end surface of the TFT substrate extends beyond the side end surface of the CF substrate to form a binding end for connecting COF, the first polarizer completely covers the TFT substrate, the first polarizer, the binding end and the end surface of the binding end are provided with packaging adhesives, and the COF portion near the end surface of the binding end is wrapped in the packaging adhesives. The invention also discloses a manufacturing method of the liquid crystal panel. The liquid crystal panel firstly connects the binding end on the TFT substrate with the COF, and then attaches the polarizer, which does not need to fill the bare binding end through dispensing, reduces the production costs, avoids circuit printing processing caused by the externally arranged TFT substrate, and simplifies the process.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, and more specifically, it relates to a liquid crystal panel and a manufacturing method thereof. Background technique [0002] The bezel-less (Bezel Less) machine of the liquid crystal display has gradually become a popular design trend. A bezel-less display refers to a display device with an extremely narrow screen frame. Design, one of its advantages is its outstanding appearance. Compared with the monitors with thick borders in the past, borderless can bring a truly horizontal screen, so that the appearance is more fashionable; another advantage is that the use of borderless Displays with bezel technology can well realize display splicing, realizing double screens, triple screens or even multiple screens, while borderless displays can maximize the effect of joint screens. In addition, the borderless display can bring users a wider visual effect, eliminating the sense of restrain...

Problems solved by technology

[0004] The first is to place the CF substrate outside as the viewing surface. At this time, the CF substrate is placed on the upper end of the TFT substrate, and a polarizer is installed on the CF substrate. Since the TFT substrate is connected to a COF (Chip On Film, overlay) after the CF substrate and polarizer are installed, crystal thin film), so the binding end connecting COF on it needs to exceed the CF substrate and the polarizer on it, and this leads to the need to process the binding end of the COF after the connection is completed, usually by dispensing Filling process, and if manual dispensing is used for dispensing filling, it is difficult to achieve standardized manufacturing due to random dispensing and poor consistency during manual work, and the fluctuation of dispensing effect is poor, which cannot meet the accuracy of dispensing process requirements, resulting in low yield and low production efficiency of LCD panels; if dispensing equipment is used for dispensing, the production cost of LCD panels is high due to the expensive dispensing equipment for this process;

[0005] The second is to place the TFT substrate externally as the viewing surface. At this time, after the COF is connected to the binding end of the TFT substrate, the metal traces on it will have an optical impact on the LCD panel. Therefore, it is necessary to print on the periphery of the TFT. Complicates the manufacturing process of the LCD panel and increases the production cost

[0006] The defects in the above existing two methods have all caused the borderless display to not be widely promoted and popularized.
