3.3: Large Area Full Color Transmissive a-Si TFT-LCD Using Low Temperature Processes on Plastic Substrate

Abstract

A 5.0-inch transmissive type plastic TFT-LCD was developed at the resolution of 400 X 3 X 300 lines (100ppi). All of the processes of TFT, color filter and LC were carried out below 150 ℃ on PES plastic films. The process conditions of TFT, color filter and LC were optimized for large area TFT-LCD on plastic substrate. The overall module including a backlight unit is of course bendable and of thickness of about 1.2 mm and 22.0g of weight, which are a third of normal glass-based display, respectively.

Properties of column spacers on a flexible color filter using a roll‐to‐roll process

“…E is a function of oscillation ω and temperature T, and in the static condition, iE′′(ω, T) and ω are negligible. On occasions, when two types of polymeric materials were tandemly arranged, the integrated strain S is expressed as S = S 1 + S 2 = P(1/E 1 + 1/E 2 ) (therefore, P = P 1 = P 2 ), (2) where P is a stress in a polymeric material. When cross section A of the material is parametric and the load W is constant, the stress P is expressed as…”

“…The choice of plastic material for the substrate is critical for sheet LCDs. Many types of plastics have been proposed as substrates for sheet LCDs, including polycarbonate (PC), polyethylene terephthalate (PET), triacetylcellulose (TAC), fiberreinforced plastic, and polyimide (PI) [6][7][8][9][10][11]. We chose to study transparent PI as a substrate for the sheet LCD because of its high thermal stability, high transmittance, and high durability.…”

“…However, glass may not suitable for flexible display since it is fragile and breakable. Plastic substrate material such as polyethylene naphthalate (PEN), polyethersulfone (PES), cyclic olefin co-polymer (COC), fiberreinforced-plastic (FRP) and polyimide (PI) were used for flexible display [1][2][3][4]. Recently, PI substrates have been used for flexible organic light emitting diodes (OLEDs) due to their thermal stability, chemical resistivity and easy casting for substrate formation [5].…”
