1.1 General
The G1213is 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 G1213 allows for direct connection with the MPU circuit without using an LCD controller. 1.2. Features + 128x 32 full dot matrix configuration + 64 duty, 179 bias + A4096-bit internal display data RAM + Aninternal display timing signal generator + S-bit parallel interface + Instructions: Display Data Read/Write, Display ON/OFF, Display Start Line, X-Address (Page) Set, Y- Address Set, and Status Read. + Three types of power supply: Voo= +5V, Vic, LEDA (LED anode) + Transflective, gray mode + Positive display Display data “H*: Display ON: blue display color Display data ”L”: Display OFF: gray background + Awide operating temperature range + Abuilt-in LED backlight (color: yellaw-green)

A 64 (SEG! to SEG64) x 64 (COM! to COM6A) dot display on the segment driver is divided into a 64 (SEG1 to SEG64) x 32 (COM1 to COM 32) dot display and a 64 (SEG! to SEG64) x 32 (COM33 to COM 64) dot display on the LCD display, located tight and left, and is configured in a 128 x 32 dot dispiay. The 8 bits of data transmitted from the MPU ig stored in the internal display RAM, and the segment signal is generated for LC drive. One bit of display RAM data corresponds to one dot lighting or non-lighting on the LC panel. -7-
