32‐4: Late‐News Paper: A 1.03‐inch 2560x2560 3514 PPI Low Power OLEDoS Backplane with In‐pixel Up‐scaling Technique

Abstract

A 1.03‐inch 2560x2560 low power OLEDoS backplane with a proposed in‐pixel up‐scaling technique is designed and implemented. Due to the proposed technique based on interpolated pixel scheme, the pixel density of the backplane realizes 3514 PPI (Pixels per Inch) with lower power consumption. The backplane has 1280x1280 input video resolution and output video resolution is upscaled to 2560x2560 without additional up‐scaler. A measured power consumption per 1 mega pixel without OLED frontplane is 16.3mW which is less than our previous 0.7‐inch 1920x1080 OLEDoS backplane with the same semiconductor fabrication process.

High‐luminance, large‐size 4K OLED microdisplays for VR/MR applications

“…Organic light-emitting diode (OLED) microdisplays have been gaining interest in the display industry for use in augmented reality/virtual reality/mixed reality (AR/VR/ MR) head-mounted displays due to their excellent image quality, high power efficiency, light weight, and compactness. [1][2][3][4][5][6][7][8] LG Display (LGD) has been developing OLED microdisplay technologies in recent years and has launched several types of OLED microdisplay panels for near-eye head-mounted display applications.…”
