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

A 4.3-inch 1058-ppi 4K liquid crystal display was fabricated using top-gate field-effect transistors (FETs) comprising a cloud-aligned 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.
