摘要： In a gradation voltage generation circuit used in a video signal line driving circuit for driving video signal lines of a liquid crystal display device by time division based on switching control signals, a first variable resistor circuit is connected between one terminal of a voltage divider circuit for generating a gradation voltage group and a power source line for supplying a high-level voltage, and a second variable resistor circuit is connected between the other terminal of the voltage divider circuit and a power source line for supplying a low-level voltage. The resistances of the variable resistor circuits are switched based on the switching control signal. Thus, in the periods in which the video signal lines respectively connected to R, G and B pixel formation portions are driven, gradation voltages that are adapted to the gradation reproducibility for R, G and B are outputted respectively.

摘要： The present invention is so arranged as to include (a) gradation reference potential generating means including a group of output terminals whose voltages are determined in accordance with a voltage division ratio of one ladder resistor, so as to output gradation reference potentials, for example, of 1024, which is a 16 multiple of a required 64-gradations; (b) output terminal designating means including a memory for designating, among from the output terminals, an output terminal for each of the 64-gradations required, in accordance with the display modes; and (c) selecting means for selecting an output terminal that corresponds to an input gradation signal, among from the output terminals designated by the output terminal designating section, and for applying a voltage via the thus selected output terminal to a display screen. With this arrangement, it is possible to attain very similar gradient signal-brightness characteristics for respective display modes with high accuracy, in order to prevent a gradient display from being changed due to switchover of the display modes.

摘要： The signal line drive circuit is provided with: a reference voltage chooser circuit for choosing one of incoming voltages in accordance with tones represented by an image signal to output the chosen voltage as a signal line drive signal; and a reference voltage line for directly transmitting first reference voltages VB1 (inclusive of a maximum voltage value VB1max and a minimum voltage value VB1min) supplied by an external reference power supply circuit to the reference voltage chooser circuit. The arrangement eliminates the need to provide a buffer circuit to a reference voltage line over which the first reference voltage is directly transmitted, thereby reducing that electric current which would otherwise flow through the buffer circuit.
