Patent JP-S6432287-A (JP)
Title: Projection type display device
Inventor: ONO TAKESHI
IPC: G09F9/00
Filed: 1987-07-28
Abstract: PURPOSE: To obtain a video equally bright as a liquid crystal panel whose numerical aperture is large by arraying plural projection optical systems where thin film transistors are integrated in a matrix state and which possess the liquid crystal panel whose numerical aperture is <1. CONSTITUTION: The projection optical system is constituted of a panel substrate 4 packaging the liquid crystal panel 5, a light source 6 and a projection lens 8. Though picture element capacity 22 and auxiliary picture element capacity 23 are recharged by selecting a gate line 15 and turning on a transistor 24, liquid crystal is stably driven when the gate line 15 is not selected because the capacity 23 is larger. An aperture part 14 is 1/4 of the area of the one picture element of the liquid crystal panel 5, and the aperture part 14 is prevented from being laid over by arranging four optical systems 1 in the shape of a square with a cross inside. Thus, brightness is made same as in the case of using the liquid crystal panel whose numerical aperture is 100% by arranging the four optical systems 1 in the case of a small numerical aperture such as 25%.  Also, the number of the picture element on a screen surface is made four times, so that the video that does not give rough feeling is obtained.
