The VATN version of WH1602B is a 2.26-inch 16x2 VATN character LCD display featuring 16 characters per line across two lines, with a 5x8 dot matrix per character. VATN (Vertically Aligned Twisted Nematic) technology provides a black background, high contrast, and wide viewing angles for displaying characters and equipment status information.
This 16x2 VATN LCD module features a COB (Chip-on-Board) structure with module dimensions of 80.0 x 36.0 x 13.2 mm (max.) for the standard WH1602B configuration and a viewing area of 66.0 x 16.0 mm. It incorporates the RW1063 controller IC, operates with a typical 5.0V logic supply, and supports an operating temperature range of -20°C to +70°C.
The display is available with red, green, blue, yellow-green, or white LED backlight options. Its negative-mode VATN display characteristics make it suitable for equipment requiring clearly visible characters and status information against a dark background, including industrial control panels, measuring instruments, UPS systems, medical equipment, and home appliances.
The WH1602B VATN LCD series offers four configurations with 6800 parallel, SPI, and I2C interface options to accommodate different host controller and mechanical design requirements:
