H20LQ061B is a 2-inch TFT LCD module with a resolution of 480×240. The driving IC is OTA5182A-C2, and it has a RGB 40-pin interface. It has strong compatibility and can be connected with mainstream microcontrollers such as STM32 and ESP32, suitable for various embedded platforms. The operating temperature range is -20℃ to +70℃, suitable for industrial environments, and has good environmental adaptability. This 2-inch TFT LCD Display, with its compact size and clear display effect, is widely used in smart devices, industrial control systems, and portable terminals. For example, in industrial control equipment: in PLC controllers, HMI human-machine interfaces, and instrumentations, a 2-inch 480×240 screen is used for real-time display of equipment status, parameter settings, and fault codes. Its high stability and wide temperature range can adapt to complex industrial environments. In medical health equipment: used in portable monitors, blood glucose meters, and blood oxygen meters, it clearly displays vital sign data. In smart wearables and portable terminals: used in smart watches, sports activity trackers, and miniature learning terminals, it provides fine picture quality and good battery life, and supports PWM dimming technology to reduce eye fatigue during long-term use.
