IPC: G02F1/13
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To realize a projection device in which the brightness of an image projected on a screen is improved and the cost thereof is reduced by simplifying an optical system. SOLUTION: Light emitted from a light source is separated to an S-polarized wave and a P-polarized wave by a polarizing by-pass prism 30. The separated S-polarized wave is reflected on and emitted from the prism 30. The P-polarized wave is by-passed through a rectangular prism 32 and a λ/2 plate, converted into the S-polarized wave and emitted from the prism 30. The S-polarized waves are split to the light beams of three primary colors R, G and B by a spectrally splitting means. Based on the light beams, the color image is formed. Then, the formed color image is projected on the screen by a projection lens 25.

Title: Driving method of display device and liquid crystal display device using the driving method
Inventor: YAMAMOTO TSUNENORI
IPC: G02F1/133
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To decrease in afterimage generated in a display device with a hysterisis in an input-display output characteristic. SOLUTION: A method of driving each pixel by AC signal is used, and as an input voltage signal therefore, a voltage 121 corresponding to an upper limit saturation is applied to a liquid crystal 131 for a fixed time period (=clear time 110), being superimposed on a signal voltage 122 corresponding to an objective display output. An optical output strength (brightness) 102 of the liquid crystal 131 changes into the upper limit saturated state 115 while applied with the clear voltage 121 corresponding to the upper limit saturation only for the clear time 110. Thereafter, the optical output strength (brightness) 102 of the liquid crystal 131 reaches an objective output strength value 116 by it that a voltage 122 corresponding to an objective display is applied to the liquid crystal 131.  Thus, an afterimage caused by the hysteresis of the input-output characteristic is decreased for displaying, and in that case, an occurrence of decrease in the picture quality and luminance flicker of the screen can be reduced.
