Abstract: An assembly structure for a display of an electronic appliance is provided. The electronic appliance includes a main body and a display for displaying an image according to an image signal input from the main body so as to facilitate the attachment and detachment of the display to and from the main body. The assembly structure includes a fitting device formed at the main body and the display. The fitting device has a fitting member which slidably fits into a fitting hole. An optical connector is provided between the main body and the display to be attached to the main body for transferring an image signal using light beams for the display.

Abstract: A liquid crystal display device includes plural pixels, video signal lines coupled to the pixels, a video signal line drive circuit, a power supply for supplying a time-varying gray scale voltage, and a display control circuit for supplying N-bit display data and N kinds of time-varying control signals. The video signal line drive circuit includes: plural switching circuits each associated with a respective one of the video signal lines and comprising N switching elements. The N switching elements each select one of the respective one of the N kinds of time control signals and a first fixed voltage in accordance with the display data. The N kinds of time control signals are such pulses as to uniquely determine a time represented by the display data based upon it. Plural logic circuits each associated with the respective video signal lines are supplied with the selected signals from the switching elements, and are configured so as to change state when all the selected signals are the first fixed voltage.
