Abstract

PURPOSE: To miniaturize a display unit which displays a picture of TV, etc., and also to reduce its power consumption by simplifying the driver circuit by reducing picture elements in number without lowering the resolution of the display picture.
CONSTITUTION: The display unit which reproduces and displays picture information, transmitted in sequence, dissolved into picture elements is provided resistance 502 connected equivalently in series to switching transistor Tr501 which integrates a picture information signal within the time for the transmission of the picture information of picture elements, and capacitor 503 between resistance 502 and display segment electrode 201. The circuit of this constitution is connected between row signal line 203 and column signal line 204, and Tr501 is made conductive by the picture information dissolved into picture elements and transmitted sequentially from each driver circuit; and charge proportional to the mean value among video signals during the conduction of Tr501 is accumulated in capacitor 503, so that picture elements can be reduced in number without deteriorating the resolution of the display picture.
