Abstract

The production of polymer‐stabilized vertically aligned (PSVA) displays requires two UV processes for liquid crystal (LC) alignments. UV1 is usually short for pre‐tilt angle formation, while UV2 takes approximately 90 minutes to consume the remaining reactive monomers (RMs). Therefore, shortening the UV2 process can significantly reduce the power consumption and maintenance costs of UV lamps during LCD fabrication. Herein, we report a novel LC material consisting of fast‐reaction RMs. With the addition of fast‐reaction RMs, the UV2 process can be dramatically decreased from 90 min to 20 min. Furthermore, the reduction of the UV2 process shows competitive optical properties, reliabilities and pre‐tilt angle stabilities compared with the reference. Overall, new fast‐reaction LC materials are beneficial to energy saving and the cost competitiveness of the company. [ABSTRACT FROM AUTHOR]

Abstract

Since the establishment of liquid crystal display industries, larger sizes, faster response, higher contrast ratio, higher resolution and lower power consumption have become a pursuing target of various panel suppliers. Considering the marvelous viewing angle of the fringe‐field switching (FFS) mode, FFS displays with a higher contrast ratio are able to show more details in the dark pictures, resulting in a much better viewing experience. Herein, to develop the next‐generation liquid crystal (LC) materials for high‐contrast FFS panels, various high‐contrast LC (HCLC) materials were designed. By minimizing Δn and maximizing Kave, HCLCs exhibited lower light leakage in dark states, leading to a higher contrast ratio compared to the reference. Two HCLCs for improving the operation voltage, transmittance, contrast ratio and response time were developed by optimizing the properties of HCLC materials. Furthermore, FFS monitors with a contrast ratio of 2820:1 and a color gamut of 96.4% NTSC were demonstrated. [ABSTRACT FROM AUTHOR]

Abstract

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 [ABSTRACT FROM AUTHOR]

Abstract

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.
