ACTIVE MATRIX TYPE DISPLAY DEVICE AND DIGITAL-ANALOG CONVERTER

摘要

An active type display device includes a plurality of video signal wires formed on a substrate, a plurality of pixels connected to the video signal wires and operated by a current signal; and a video signal driver for supplying a video current to the pixels via the video signal wirers according to a data signal supplied from an external circuit. The video signal driver includes a plurality of DA sections (341) for conversion into the video current (Idn) by adding at least one of a plurality of gradation reference currents (Ic) stored and held by a constant current storage circuit (342) according to the data signal (Dn).
