Definitions

  • the invention relates to a matrix driven display apparatus for use in portable phones such as cellular phones.
  • the display section 41 has a multiplicity of common electrodes (not shown) extending in the direction of X axis and a multiplicity of segment electrodes (not shown) extending in the direction perpendicular to the common electrodes, i.e. in the direction of Y axis, forming together a matrix of electrodes for activating selected LCD elements or pixels.
  • a pixel will be turned on if it is activated by both the segment electrode and the common electrode associated with it.
  • the common electrodes are each connected, by means of lead wires, with associated right common electrode leads 42 on the right end of the LCD or left common electrode leads 43 on the left end of the LCD.
  • the segment electrodes are each connected with respective segment electrode leads 44 at the lower end of the LCD section 41.
  • a drive unit 30 including a drive IC device 16 as shown in Fig. 1.
  • the unit includes a tape carrier package 15 on which the drive IC device 16 is mounted, and common leads 19 for connecting the common terminals COMMON with an external device, right segment leads 17 for connecting the right segment terminals of the device 16 with another external device, left segment leads 18 for connecting the right segment terminals of the device 16 with another external device, and input leads 20 for connecting the input terminals INPUT of the device 16 with a further external device.
  • the common terminals of the drive IC device 16 are connected with the segment electrodes of the LCD section 11 via the segment leads 14, so that scanning of the LCD will be performed through the segment electrodes.
  • the common electrodes are set to a predetermined potential in accord with the selection signal received through the input leads 20.
  • the segment electrodes will be scanned in sequence, defining matrix points of pixels where the selected electrodes are scanned by the scanning, thereby activating these pixels to display the picture information on the LCD 11.
