128x64 Monochrome Graphic Display
Our 64128M monochrome graphic LCD module has a viewing area of 70 x 40 mm and is the largest of our standard 128 x 64 LCD displays. This LCD is available with several different backlight colors and is widely used in industries such as home automation and test and measurement equipment. The COG IC is the Sitronix ST7565R. This LCD has a THRU-HOLE PIN interface.
The ST7565R is a single-chip dot matrix LCD driver that can be connected directly to a microprocessor bus. 8-bit parallel or 4-line SPI display data sent from the microprocessor is stored in the internal display data RAM and the chip generates a LCD drive signal independent of the microprocessor. Because the chips in the ST7565R contain 65x132 bits of display data RAM and there is a 1-to-1 correspondence between the LCD panel pixels and the internal RAM bits, these chips enable displays with a high degree of freedom. The ST7565R chips contain 65 common output circuits and 132 segment output circuits, so that a single chip can drive a 65x132 dot display (capable of displaying 8 columns x4 rows of a 16x16 dot kanji font).
