CCD Camera on LCD Panel

   Disclosed is a mounting method of CCD (Charge" "Coupled"
Device) camera system on LCD (Liquid Crystal Display) panel.  A
built-in CCD camera on LCD panel used in mobile PC has wide
application such as video phone and input images.  Therefore
lightweight, small size and low cost are realized by mounting CCD
camera system on LCD panel.

   As a schematic illustration, CCD device (2) is formed on
alleys side glass substrate (1) by semiconductor process, or CCD
device is located on this glass by Chip on Glass technique.  The
figure shows liquid crystal (7), glass substrate and polarizer (8).
Camera system wiring is on glass as TFT alley.  Lens unit (4) is also
located on alley side glass as the figure.  Lens unit space (5) uses
back light unit (3) space.  Reflector (6) is used for focuses image
on CCD side as the figure by the application of light guide of back
light unit.

   This method is applicable to mount CCD camera system on
LCD panel and is very compact.  The product cost is also able to
decrease.
