240x128 Monochrome Graphic Display
Our 128240C monochrome graphic LCD module has a viewing area of 70 x 35 mm and offers grey-scale performance. The 128240C is the same mechanical size as our 64128M, however it has a slightly narrower viewing area due to the higher resolution. 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 ST7529. This LCD has a FPC interface.
The ST7529 is a driver & controller LSI for 32 gray scale graphic dot-matrix liquid crystal display systems. It generates 255 Segment and 160 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral Interface (SPI), 8-bit/16-bit parallel or IIC display data and stores in an on-chip display data RAM. It performs display data RAM read/write operation with no external operating clock to minimize power consumption. In addition, because it contains power supply circuits necessary to drive the liquid crystal, it is possible to make a display system with the fewest components.
