The world's largest LTPS 8K monitor with Low Temperature Poly‐Silicon (LTPS) thin‐film transistor (TFT) is developed to have high performance and ready for mass‐production. With new process and panel design, we have realized the 32‐inch 8K LTPS display with 120Hz high frame rate and GOA driving. In this article, the challenges and related technology for large‐size 8K monitor will be discussed. Furthermore, a new LTPS panel design will be proposed to reduce gate loading and improve the uniformity of common voltage (Vcom).

The formation mechanism of press mura in 2-domain FFS-LCD is investigated. We analyze LC directors by comparing the brightness with rotated polarizer and 3D simulation. The relation of press mura and pixel edge designs is also discussed. Additionally, the press-mura phenomenon of negative LC is also reported.
