18‐5: A 1058‐ppi 4K Ultrahigh‐Resolution and High Aperture LCD with Transparent Pixels using OS/OC Technology

Abstract

A 4.3-inch 1058-ppi 4K liquid crystal display was fabricated using top-gate field-effect transistors (FETs) comprising a cloudaligned composite oxide semiconductor. For transparent pixels comprising an oxide semiconductor/oxide conductor (OS/OC), FETs, wirings, capacitors, and contacts in the pixels are transparent. This display achieves a 63.6 aperture ratio and low power consumption.

High resolution photolithography for direct view active matrix organic light‐emitting diode augmented reality displays

“…). To realize all of the above, we need both pixel pitch down‐scaling known for microdisplays (CMOS background) and backplane size up‐scaling known for flat‐panel‐displays [FPD— thin‐film transistors (TFT) background]. Switching to advanced nodes in flat panel backplane manufacturing can result in ultra‐high definition, direct‐view AR displays fabricated in a cost‐effective way.…”

“…1). To realize all of the above, we need both the microdisplay-like pixel pitch downscaling (CMOS background [3]) and the flat-panel-display-like (FPD) backplane size up-scaling (TFT background [4,5]). Switching to advanced nodes in flat panel backplane manufacturing can result in ultra-high definition, direct-view AR displays fabricated in a cost-effective way.…”

Foveated imaging for near-eye displays

“…No matter for liquid crystal display (LCD) or organic light emitting diode (OLED) display, it will be a very challenging task to integrate over 36 million (6K × 6K) pixels on such a small display panel. Thanks to the tremendous efforts of panel manufactures [4][5][6][7][8][9], the VR display resolution has been pushed to around 4K × 4K recently [4], although there is still a long way to go for lowcost mass production. In addition, the new driving circuitry designs are also required [9,10] due to the much shorter addressing time for each scan line.…”
