The around Mura is a common defect of TFT_LCD. In this paper, the analysis of around Mura on the black and low gray level shows that the around display unevenness caused by the difference between the Transmittance and color coordinates of the Cell gap anomaly. Due to the poor design and process of the Dummy area, the AA edge glass Bending caused the unevenness of the around Cellgap. Through optimization of design and process, this paper effectively improves the issue; and gives the Dummy area related design optimization suggestions and process choices, which fundamentally solves around mura

Methoxy‐bridge polar monomer has high dielectric anisotropy, which can reduce the driving voltage of the panel and save energy; olefinic‐chain monomer can effectively reduce the rotational viscosity and improve the response speed of the panel, while the polar alkene monomer has both low rotational viscosity and high dielectric anisotropy, which has a good application prospect. At present, the industry does not have too much verification and analysis of the collocation about the collocation of two monomers. In this paper, the reliability of liquid crystal materials containing polar methoxide monomers and polar alkene monomer was tested. The results showed that VHR (Voltage Holding Ratio) performance was worse in the experimental group with the two monomers. And with the extension of UV irradiation time, the difference between the experimental group and the control group was more obvious. A further test of IS (Image Sticking) was conducted on a 32‐inch display platform. The results showed that the liquid crystal containing both two monomers was tested NG, while the control group was OK.

The article studied the 8K product in the black and white checkerboard test, because the 8K product Pixel design is reduced, the in‐plane circuit is increased, and there is a lateral electric field in the black and white area, which causes the ion to move and form a line afterimage. This article describes the adjustment The DBS voltage forms a vertical electric field in the middle of the pixel, which is similar to adding an example of a moving speed bump to prevent the lateral movement of ions, thereby improving the afterimage at the black and white junction.

In this article, we study how to improve the irregular Mura in the surrounding and corner of GOA (Gate Driver on Array) product in high temperature and high humidity HTHHO (60/90) environment, because of the influence of PI Halo area. This article illustrates that by adjusting the PI phase separation ,adjusting the PI drop position and adjustment of coating position of Seal ,which can reduce the influence of PI and improve the around mura. The experimental results show that increasing PPO (PI prebake oven) temperature can accelerate the separation of PI phase, allow PI to form faster and improve the around mura. By modifying the Pattern coated by PI, the PI is expanded and the around mura. can be improved. Adjusting Seal location also improves Mura around the site.
