Title: Liquid crystal display device
Inventor: TOMITANI HIROSHI
IPC: G09G3/20
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device which eliminates beltlike display gradation unevenness and is small in power consumption and simple in circuit constitution by varying the waveform width of a scanning signal waveform applied to a scanning electrode to be scanned according to a display ON number and controlling a voltage so that the display gradation unevenness is canceled. SOLUTION: A counting circuit 39 counts how many times display data sent from a control circuit 36 turns on a pixel 30 in one operation period. The display state of liquid crystal can be detected by counting the number of pixels 30 which are switched on. An arithmetic circuit 38 performs specific operation for display data of each scanning line counted by the counting circuit 39. A pulse width control signal generating circuit 37 generates a control signal for increasing or decreasing the pulse width of the scanning signal according to the result of the operation performed by the arithmetic circuit 38 and supplies it to a scanning line signal driving circuit 34. Here, the pulse width is widened to compensate an execution voltage which is lost owing to waveform rounding.
