摘要： A multi-gradation liquid crystal display having dual display definition modes that can display both TV pictures and office automation images, both without flicker. Scanning electrodes extend in a first direction. Scanning and non-scanning voltages are selectively applied to the scanning electrodes. Signal electrodes extend in a second direction perpendicular to the first direction. First and second signal voltages are selectively applied to the signal electrodes. A layer of liquid crystal is sandwiched between the scanning and signal electrodes. Mode switching is provided for switching display between a first mode wherein an image is displayed by two-gradation pixels and a second mode wherein an image is displayed by three or more gradation pixels.

摘要： According to one embodiment, a video display device includes a housing, a display module, a wall portion, a first circuit board and a second circuit board. The housing houses at least part of the display module. The wall portion is located opposite the display screen with respect to the display module. The first circuit board includes an input signal processing circuit that outputs at least video data from an input signal. The second circuit board includes a frame rate converter circuit and a timing control circuit. The frame rate converter circuit generates an interpolation frame based on frames of the video data received from the input signal processing circuit and outputs the video data with an increased frame rate. The timing control circuit outputs a timing control signal to a driver circuit that drives the display module based on the video data received from the frame rate converter circuit.
