1. GENERAL
1.1 General
The G1216 is a very thin LCD module on which a full-dot matrix LCD panel and a CMOS IC driver are
integrated. The LCD panel used here features wide viewing angle and high contrast. This full dot
configuration allows a wide variety of patterns to be displayed depending upon the input data. The
display position is the intersection point of the matrix transparent electrodes. This prevents display
distortion and displacement. Incorporating a display RAM and a display timing signal generator into the
G1216 allows for direct connection with the MPU circuit without using an LCD controller.
