ABSTRACT:
A flickerproof retaining structure for a liquid crystal display is disclosed. The retaining structure comprises an elastic pad disposed under a lower face of the display and a peripheral supporting frame located under the elastic pad to support the same. The peripheral supporting frame is formed on a housing and profiled corresponding to a peripheral sealed portion of the display. The peripheral supporting frame has an upper edge portion supporting and abutting against a bottom face of the sealed portion of the display, whereby a housing deforming force such as key depressing force exerted on said housing will be only transmitted through the peripheral supporting frame and the elastic pad to the sealed portion of the display without compressing a liquid crystal zone of the display so that no flickering of characters displayed on the display will take place due to the housing deforming force.
