摘要：

A prototype 97.5-inch 8Kx4K a-Si liquid crystal display (LCD) panel for Super Hi-Vision with ultra-high definition was successfully developed using the BOE exclusive advanced super-dimensional switching technology. This LCD has a panel with 7680(x 3) by 4320 pixels, 16 times those of the conventional Full High Definition (FHD), and the pixel size of the panel is 0.2811mm (90.4 pixels per inch). The liquid crystal charging time was extended by quad area and double source line structure (also called "2G2D driving"). Additionally, a multi-functional image-processing video board was developed to compatibly realize the real-time display of huge image data from FHD to 8 K. Furthermore, the reason for the arcing that occurred in half-tone source-drain mask etching was discussed and was ultimately solved by improving the exposure process. The demonstrated panel features a 1200: 1 contrast ratio, 500 nit brightness, and 72% color gamut.
