摘要： A liquid crystal display device has a circuit for selecting voltage levels based upon display data from an externally-supplied gray-scale voltage varying periodically. The circuit includes a plurality of series combinations of processing circuits. Each of the series combinations is associated with one of video signal lines coupled to pixels, and each of the processing circuits of a respective one of the plural series combinations is associated with a respective one of N display data lines for supplying the display data and with a respective one of plural time control signal lines for supplying time control signals varying in synchronism with the gray-scale voltage. Each of the processing circuits is disposed between two adjacent ones of the N display data lines. The time control signals uniquely determine one level of the gray-scale voltage in combination with the time control signals.

摘要： In the display device which is used in a miniaturized portable equipment, when a drive circuit is also connected on the same substrate as pixels, an input signal of low voltage has a level thereof shifted even when the threshold value is large or fluctuated. The display device includes pixel electrodes, switching elements which supply video signals to the pixel electrodes, and a drive circuit which supplies the video signals to the switching elements on the same substrate, wherein the drive circuit includes a level shift circuit, the level shift circuit includes a transistor. In a state that the transistor assumes an ON state, when an input signal is inputted to a source terminal and the input signal is at a low voltage level, a drain terminal assumes a low voltage level. Further, even when the input signal is at a high voltage level equal to or lower than a threshold value, the drain terminal outputs a voltage equal to or more than the threshold value as a high level voltage.

摘要： A display device for use in compact portable devices is configured for assigning gray levels according to the pixel area ratio and, further includes a digital-to-analog (D-A) conversion circuit for converting digital data to gray-level voltage or analog signals. This configuration reduces the size of the circuit for D-A conversion, thus reducing the space for the driving circuit when assigning gray levels according to the pixel area ratio. The combination of the gray-level voltage output from the driving circuit and the gray-level assignment according to the pixel area ratio reduces the scale of the circuit.
