28.1: Premium Picture Quality by Super‐Multi‐Domain Polymer Sustained Alignment LCD Technology

Abstract

New super‐multi‐domain polymer sustained alignment (PSA) liquid crystal displays are developed With this new pixel architecture, premium picture quality with very little oblique gamma distortion and color shift (Δ u‘v’ < 0.02) like in‐plane switching (IPS) mode, is obtained. Moreover, it can also realize low‐crosstalk patterned retarder 3D displays without sacrificing the 2D‐mode luminance.

Prospects and challenges of mini‐LED, OLED, and micro‐LED displays

“…To create multiple domains, each pixel is divided into several subpixels via patterned electrodes 92 or physical protrusions. 93 Four-domain, eightdomain, 94 and 12-domain 95 VA configurations have been proposed to reduce gamma shift and color washout at large angles. For compensation films, a combination of two A plates and two C plates 96 or a combination of one A plate and one C plate has been proposed to reduce the off-axis light leakage from the VA LC and crossed polarizers.…”

P‐93: Skin Color in Side View Improvement via a Novel ITO Slit Design

“…Moreover, polymer sustained alignment (PSA) cell technology with superior cell transmittance and response time was developed [2] and has been widely adopted in mass production [3]. The side-view gamma distortion of the 4domain pixel causes significant color shift at large viewing angles, which induces the phenomenon of color washout [4][5][6][7][8], especially perceivable for human-skin colors. The skin color mostly appears in movies, advertisements and dramas, and the skin-color difference is easily recognized due to the human impression.…”

Polymer layer and tilt angle of polymer-sustained-alignment liquid crystal displays

“…PSA-LCD technology has been widely studied and also adopted industrially for televisions, mobile phones and other devices. [4][5][6][7][8][9][10][11] The fabrication of a PSA-LCD is as follows: 3) 1) The LCD has two substrates. One of the substrates has minutely patterned transparent electrodes and the other is covered entirely by a transparent electrode.…”
