Title: Variable light passing area type liquid crystal optical shutter
Inventor: KOSHIISHI BUNJI
IPC: G02F1/13
Filed: 1989-02-03
Abstract: PURPOSE:To obtain an image display device using liquid crystal which provides picture quality equivalent to that of a cathode-ray tube in terms of easiness to see, definition, etc., by varying the area of light passage in one picture element like the stop of a camera and making a gradational display. CONSTITUTION:Grooves are formed in a V or corrugated shape in either or both of picture element electrodes E and a common electrode in one picture element of an active TN type dot matrix liquid crystal optical shutter which uses MIM instead of TFT. Then the differences between electrodes are made different and the intensity of an electric field is varied with the place; and the area of the phase shift of liquid crystal is increased or decreased by varying an effective voltage applied between the electrodes by vary the area of light passage. Namely, when the voltage between the electrodes is varied, the TN liquid crystal shifts in phase from the place where the distance between the electrodes is short (the electric field intensity is large) to pass or cut off light, and the area of light passage varies to make the gradational display. Consequently, visual angle dependency is small, so an image is seen sharply in any direction.

Abstract: PURPOSE:To perform bootstrap operation completely by providing the 1st and 2nd MISFETs at both terminals of a bootstraping capacitor and by applying in-phase signals to their gates. CONSTITUTION:The current performance of MISFETQ7 should be much greater than that of FETQ2.
