42.2: A New Conductor Structure for Plastic LCD Applications Utilizing “All Dry” Digital Laser Patterning

Abstract

A new conductor material has been developed for plastic film LCD applications [1]. This highly durable conductor has very low sheet resistance (under 10 ohms/square), high optical transmission (over 83%), low birefringence (less than 10 nm), good chemical resistance, very low oxygen & moisture permeability, and excellent thermal and environmental stability. An "all dry" digital laser ablation process was also developed for patterning the conductors.

Integral‐Color Plastic Liquid Crystal Display The Ultimate Flat Panel Display

“…It is essential, therefore, to adopt two additional technologies to shrink the display thickness. 3 The first is the use of plastic liquid crystal panels 4 . With 75-µm plastic substrates, the individual liquid crystal panels may be made with a thickness of approximately 155-µm.…”

Transparent flexible plastic substrates for organic light-emitting devices

“…A multilayer composition for both substrates is very similar. We define dry-etchable and wet-etchable plastic substrates as the plastic substrate coated with a TCE that can be etched either by a laser-based method (dry-etchable) 17,18 or by a wet chemical process (wet-etchable), 19 respectively.…”

“…The acrylic and lowtemperature amorphous silicon oxide (a-SiOx) was used as a hard coat and oxygen/moisture barrier, respectively. [17][18][19] To further reduce the water vapor and oxygen transmission through the plastic substrate, additional layers have been deposited on one side of the plastic substrate, which are indicated as additional low-temperature coating layers in Fig. 1a.…”

“…35 We also used the laser-based method to pattern the TCE on dry-etchable plastic substrates. 18 More recently, the wet-etching capability for TCE on wet-etchable plastic substrates was developed 19 and used in this study.…”

Methods for creating a multi-axis polarizer for visible light attenuation by linear translation

“…When the mirror is flipped, the image is reflected from the front side of the prism, not the backside. 8 External mirrors are simpler yet. They usually consist of a planar or convex mirror, depending upon which side of the car, a backing plate attached to an actuator (mechanical or electric to control position only), and a frame or housing.…”
