Dot Matrix Display having Inequality Density

   Disclosed is a dot matrix display device having inequality
density.

This display device has different size pixels.
On this device, the original image data area is not depend on the display p
So high pixel density area can display the original image in high quality,
If the center area has higher quality than outside area, it's effective for
Of course, the same function is possible to use the display having high qua

Disclosed display device can be lower cost solution than equality density d

The following figure indicates some applications.
