Serial Lcd Display Module are Character LCD Modules with integrated RS232, I2C and SPI serial interfaces with a broad range of industry standard sizes in 2x16, 2x20, and 4x20 modules.COG (Chip-On-Glass) displays are monochromatic passive or active matrix LCD displays that can display information as text or in a dot matrix pattern. Since COG LCD display don't have a built-in PCB board, the IC is directly mounted on the glass of the display.
Access to information mainly through display and interactive interface with the electronic technology and electronics integrated rapid development of LCD modules in the smart instrumentation to achieve a mix of graphics and text display, man-machine dialogue to achieve the on-screen menu operation thus graphic LCD module with its small size, low power consumption, the development cycle is short, safe, reliable, flexible, etc., in the smart meter has been more widely used.
