摘要： A method of driving a gray scale and a drive circuit therefor are provided in which the simplification and reduction of the operating speed of a circuit for generating display voltages in a matrix display device are promoted, and low cost and multi-color display of high minuteness are simultaneously realized. The display circuit for generating the display voltages is composed of an image signal processing circuit for dividing an input digital image signal into plural bit groups, a first display voltage generating circuit for generating the display voltages corresponding to the first bit group obtained by the division, a second display voltage generating circuit for generating the display voltages corresponding to the second bit group obtained by the division, and a line-at-a-time timing circuit. The first and second display voltage generating circuits are operated in parallel to combine the outputs thereof with one another, thereby to generate a gray scale displaying voltage.

摘要： In a liquid crystal apparatus in which a white light of a fluorescent tube corresponding to a linear light source repeats plural times of diffusions and reflections between a reflection sheet and a diffusion plate, and is thereafter input as a back light to a liquid crystal panel corresponding to a display screen, an object of the invention is to make it possible to secure a brightness uniformity even if the liquid crystal apparatus is thinned. It is possible to prevent a brightness unevenness caused by a short distance from the reflection sheet to the diffusion plate, by preventing a deformation (a deformation which is convex toward the fluorescent tube) of the diffusion plate due to a thermal expansion of the diffusion plate caused by a heat generation of the fluorescent tube, by arranging at least one pin mold hold so as to support a portion near an approximately center of the diffusion plate.
