P‐10.1: Analysis and Improvement of Yellowish RLCD

Abstract

The low power consumption of RLCDs has significant advantages over traditional display solutions, making it a competitive candidate for next‐generation green displays. However, in some cases, improper design may cause the RLCD to turn yellowish, causing display distortion. To solve this, we proposed a series of methods to solve such color cast problems. In this paper, the reflectance associated with the phase state between the circular polarizer and the liquid crystal has been adjusted by liquid crystal to decrease this color cast. By redesigning the liquid crystal parameters, the color deviation has been successfully improved. Finally, the samples produced on production lines verified that the Improvement Scheme did make the yellowish panel whiter.

25‐1: Invited Paper: Improvement of Viewing Angle and Color Gamut of Twisted Nematic Liquid Crystal Display using Inkjet‐printed Quantum Rod Color Pixel Converter

“…Four types of display devices have been proposed based on use of these QRs, including a backlight, emissive color pixels for use with liquid crystal displays (LCDs) and blue organic light-emitting diode (OLED) displays, and a quantum dot (QD)-based light-emitting diode (LED) display [3,7]. Here, we explore the use of QRs in emissive color pixels when they are combined in an LCD structure [9,10,11], as shown in Fig. 1…”
