LTC-4727WC Application Field and Working PrincipleThe LTC-4727WC display module is a liquid crystal display (LCD) module targeting outdoor applications. Manufactured by Lite-On Technology Corporation, the module is constructed of an LCD with a high contrast LCD panel and a separate LED character and numeric, 7 segment characters and numeric backlighting. The module is suitable for outdoor use in a wide range of ambient temperatures and humidity levels.The LED character and numeric display of the LTC-4727WC display module consists of seven segment characters, as divided into different elements. Each segment is composed of four LEDs arranged in a line to emit light information. The LED character number can reach up to 8 digits, and the LED character and numeric display angle is wide and the viewing angle can be adjusted in the range of 0°-180°. In addition, the module also provides a backlight brightness control driver, which can improve the brightness adjustment range from 0% to 100%.The principles of LTC-4727WC display module is an active low design drive circuit module, where LED current is regulated by PWM (pulse width modulation) technology. With the help of PWM technology, the LED output current can be adjusted from 0-100%, which can effectively regulate the light intensity and energy consumption of display module by controlling the turn-on and turn-off time of LEDs. The main functions of LTC-4727WC display module include brightness adjustment, over-temperature protection and ESD protection. The LTC-4727WC display module has many advantages, such as wide voltage range, wide temperature range, long life and high reliability. Its wide voltage range (9V to 15V) allows the module to be powered by a wide range of power supplies, and its wide temperature range (0°C to +70°C) makes it suitable for use in a variety of outdoor/indoor applications. In addition, its long life (up to 100000 hours) ensures that the module can be used for a long period of time without requiring frequent maintenance. Lastly, its high reliability ensures that the performance of the module remains consistent even in extreme environments.The LTC-4727WC display module is mainly used in outdoor display applications. For example, it can be used in portable electronic devices to display time and other related information. It can also be used in automotive applications such as displays for car battery level and air conditioning temperature. In addition, LTC-4727WC can be used in signs and billboards to maintain the advertising effect in challenging environments, such as in the amusement park, even at night. In conclusion, the LTC-4727WC is a display module designed for outdoor use that is highly reliable and efficient. Its LED character and numeric display is backed by a high contrast LCD panel, allowing it to work in a wide range of temperatures and humidity levels. The module’s wide voltage and temperature range, long life and high reliability make it suitable for use in a variety of outdoor and indoor applications.
