White Blue Backlight VATN Monochrome LCD Screen

White Blue Backlight VATN Monochrome LCD Screen 

Description

White and blue backlit VATN single-color LCD screen. The core technology is VATN (Vertical Alignment TN) liquid crystal technology. It is a negative display single-color screen. The typical visual effect is black background with white characters / blue background with white characters. It is equipped with white or blue LED backlight, featuring high contrast and sharp text.

Core principle: When the power is off, the liquid crystal molecules are arranged vertically, forming a pure black background; when the power is on, the molecules rotate to allow light to pass through, presenting clear white text and graphics. No crossed polarizers are needed, and there are no ghost images or wide viewing angles.
Optical properties: The contrast ratio can reach 120:1 to 1000:1. The horizontal viewing angle is approximately 170°, and the vertical viewing angle is approximately 110°. The backlight can be either pure white or ice blue. It is clearly visible in both low light and strong light conditions.
Electrical and environmental: The working voltage is 3.0 to 5.0V, with low power consumption. The temperature range is **-30℃ to 85℃**, suitable for harsh industrial and vehicle environments.
Form and interface: Common segment display screens, character screens (16×2/20×2), and graphic screens (128×64); the interfaces are mostly COB/COG, SPI/I2C/MCU. The size is small and easy to embed.

Main purpose

Industrial Control: PLC, frequency converters, temperature controllers, instruments and meters, display parameters, status and alarm codes.
Household Appliances: Refrigerators, air conditioners, washing machines, microwave ovens, display temperature, mode, timing, etc.
Vehicle Electronics: Dashboard, central control screen, tire pressure monitoring, compatible with vehicle scenarios in wide temperature and wide viewing angle.
Consumer Electronics: Blood glucose meters, electronic scales, chargers, handheld devices, low power consumption, high cost performance.
Office and Commercial: Attendance machines, cash registers, elevator displays, clear and legible, long-term stable.
