A homogeneously aligned liquid crystal layer on a substrate film on which it is not necessary to form an alignment film can be fabricated by using a slit coater. The electro-optical performance of TN-LCDs was demonstrated. The surface azimuthal anchoring energy and the mechanism on the surface alignment are discussed.
Recently, thinner cover glass has been required therefore the glass strength has been more important. It was found that surface polishing of the glass after chemical strengthening improved surface strength of the glass. In chemical strengthening process water in the atmosphere enters the glass surface and creates chemical defects. The surface strength is improved by removing them.
We have developed a prototype full-resolution Super Hi-Vision (SHV) plasma display panel (PDP) that has 4,320 scanning lines and over 33 million pixels. SHV has four times as many scanning lines as Hi-Vision, so it requires high speed driving. To drive 4,320 scanning lines stably, we applied a new driving method to the prototype PDP. The highly realistic SHV programs were the first successfully to be reproduced on 145-inch diagonal PDPs with 0.417-mm pixel pitch. We evaluated the image quality of the prototype SHV PDP and confirmed that it had a wide viewing angle and over 4,000 TV lines for a static image.
We propose a measure of quality for the color tone of images. This measure concerns the degree of mesopic color in an image. The mesopic degree is evaluated by transforming the color in the image to daylight colors under the condition that the input image includes mesopic colors. This color transformation is the inverse of the transform of image colors to mesopic colors. We use a simple mesopic transform method and calculate this mesopic degree for some images of impressionist paintings.
