发明名称 IMAGE DISPLAY APPARATUS AND DRIVE CIRCUIT THEREOF
摘要 A data driver circuit which enables the square measure of the non-display areas of image display devices to be reduced is to be provided. The driver circuit has two DA converters which convert the digital signals, in accordance with more significant bits thereof, into analog voltages; a voltage divider which divides the output voltages of the two DA converters in accordance with less significant bits of the signals; and a shift register which generates trigger signals in synchronism with the digital signals. The voltage divider, arranged in the gap between the two DA converters, comprises memory elements arrayed in two-dimensional matrixes, and a plurality of resistive wirings. The memory elements store decoded signals generated by the decoders in synchronism with the trigger signals, and selectively supply, in accordance with the decoded signals stored by the memory elements, the divided voltages which derive from the two DA converters and are generated on the resistive wirings.
