Title: Reflection preventing device of cathode ray tube screen due to ambient light
Inventor: YAMANO HACHIROU
IPC: H01J29/89
Filed: 1982-05-10
Abstract: PURPOSE:To observe a picture clearly with a noraml attitude, by fitting a reflection preventing plate adjustable for the angle and length to a frame surrounding a cathode ray tube and preventing the reflection of light on the cathode ray tube screen. CONSTITUTION:The length of the reflection preventing plate 6 is adjusted by expanding and shrinking the plate 6 toward the arrow (b) and its angle is adjusted by turning the plate 6 toward the arrow (a). Thus, even if an angle to the cathode ray tube screen 4 is different from viewers, since the angle and the length of the reflection plate 6 are adjusted accordingly, no reflection of light on the cathode ray tube 4 exists and the reflection preventing plate 6 is fixed easily at a position where a viewer of normal attitude observes the picture clearly. When a monitor television 1 is not used, the reflecting plate 6 is folded small and contained in the inside of the surrounding frame 7.

Title: Method of driving liquid crystal electro-optical element
Inventor: TANAKA TAKAAKI
IPC: G02F1/133
Filed: 1991-04-11
Abstract: PURPOSE:To perform time sharing drive of an anti-ferroelectric liquid crystal element which shows three-conditional switching behavior by enlarging the driving voltage margin and operating temperature margin of the element to shorten a screen scanning time and restraining the deviation of electric charge due to liquid crystal spontaneous polarization to prevent the deterioration in electro-optical property. CONSTITUTION:Selected waveforms are applied only to scanning electrodes in which display information reload occurs by using a partial scanning method to restrain the flickering of a screen and enhance display quality. The driving voltage waveforms of scanning electrodes C1-C6 are made into alternating current so that the average value per time of voltage actually applied to a liquid crystal layer including a counter electric field due to liquid crystal spontaneous polarization can be zero. A time required for screen scanning is shortened by setting a removal period required for relaxation from ferroelectric phase into anti-ferroelectric phase within a non-selection period, and an operating temperature margin is enlarged by changing the length of a removal period with temperature reliability in a response relaxation time.
