It is suitable for industrial application, cost competitive solutions and can be total custom making the LCD dimensions, segments display patterns based on differerence applications. the SPI or I2C LCD interface could save the MCU port and easily connect the MCU with faster data speed.
The VA TN LCD mode bring the LCD with high contrast than other TN or stn lcd panel, because it has a more black background, and it has the wider viewing angle than other TN or STN LCD, so the VA TN lcd is a good choice for the high class production application.
Four colors segment display bring a wonderful color display effect than other monochrome lcd panel. it is suitable for the application that no need the full colors display, the color segments display only need small ROM for the MCU.
The SPI / I2C lcd interface also save the interface ports to the MCU.
