HIGH CONTRAST, WIDE VIEWING ANGLE LCD LIGHT-SWITCHING ELEMENT |
摘要 |
<p>The invention suggests a new concept of an LC light switching element, which allows excellent angle compensation of dimming light by using a simple c-panel with negative double-refraction in the compensation layer. The concept is based on simultaneous application of a high angle symmetrical STN LC structure (preferably 180 degrees distortion) and maximum application of one of the two inherent ways of the passing of light (preferably ordinary ray). The solution is best suited for various applications in switching light like protective welding filters, as well as multi-segment large displays, where it provides a high level of uniformity of dimming light in the closed (dark) state.</p> |
