85‐2: 2117PPI VR LCD with ultra‐high aperture opening ratio

Abstract

In this paper, the Pixel Design and the Process Technology of ultra‐high PPI display are investigated. For increasing the aperture open ratio in pixel design, the width of metal data line, the size of TFT and the crosstalk between metal lines are separately researched. The minimum of light shield for LTPS TFT is achieved since the mechanism between photoillumination and off‐state current is analyzed. In the meanwhile, the process of narrow metal lines and small via holes are developed. For conclusion, the aperture open ratio of backplane panel is achieved more than 55%.

Enhancing virtual reality with high-resolution light field liquid crystal display technology

“…However, recent advancements in display technology have introduced 4k VR LCDs, as highlighted in the 2023 SID conference by both Innolux Corp. 16 and BOE Technology Group. 17 Incorporating this new technological development, along with the LF techniques described in this paper, holds the potential to enhance the resolution of LF displays. Additionally, it enables the expansion of the eyebox, currently at 6.4 mm, surpassing the current limit of 15 PPD, thus further improving the overall visual experience.…”
