4-1:Invited Paper: Roll TFT-LCD with 20R Curvature using Optically Compensated Colorless-Polyimide Substrate

Abstract

Colorless polyimide liquid crystal display (CPI-LCD) was successfully fabricated by PI-LCD handling process which contained substrate coating, LCD manufacture and dualsubstrate laser lift-off (LLO) process. Plastic substrate was made by high transmittance CPI material (T > 91%). Total cell thickness without polarizer is less than 25 ȝm.

Highly transparent, ultra‐thin flexible, full‐color mini‐LED display with indium–gallium–zinc oxide thin‐film transistor substrate

“…Micro‐LED and Mini‐LED technologies are considered as the best solution for flexible display and transparent display. Different from LCDs, Micro‐LED and Mini‐LED are solid‐state and self‐emitting display, which is superior in terms of response time,contrast ratio, brightness, and ultra‐thinness 4–7 . In addition, LEDs as individual emitting devices, LEDs could be large‐scale assembled onto various substrates ranging from glass to rubber and plastic 8,9 .…”

Curved vertical‐alignment liquid crystal display with uniform brightness: From pixel design to verification

“…Benefit from the great viewing experience, curved liquid crystal display (LCD) are integrated into various products, including TVs, monitors, and automotive displays, leading to the remarkably increasing demands of curved LCD panels in the market recently 1–3 . Although the active‐matrix organic light‐emitting diode (AMOLED) is also a good candidate for curved displays, in certain application areas that no repeated bending is required and the radius of curvature is adaptable, the curved LCD is more competitive due to its relatively low cost and mature manufacturing process 4–8 …”

43‐3: 14 Inch Flexible LCD Panel with Colorless Polyimide

“…In certain application area that no repeated bending is required and the radius of curvature is adaptable, flexible LCD should be competitive. [1][2][3][4][5] To realize the small curvature of an display panel, the ultra-thin glass should be a candidate. However, the plalstic substrate is more adapted to multi-curved display.…”
