Outdoor automatic locker 21.5 inch sunlight readable screen solution
1. Project Background
With the popularity of smart logistics and contactless services, outdoor automatic lockers have been widely used in residential areas, business districts, transportation hubs, campuses, scenic spots, industrial parks and other places. As the human-computer interaction window of the locker, the display screen undertakes important functions such as information guidance, operation prompts, identity confirmation, and status display. However, in outdoor deployment environments, traditional display screens face challenges such as strong light reflection, poor visibility, short service life, and susceptibility to environmental influences, which seriously affect user experience and equipment stability.
This white paper introduces a set of sunlight readable display solutions based on 21.5-inch industrial-grade high-brightness LCD modules, designed for outdoor automatic locker manufacturers, providing high-reliability display components that are clearly visible, stable, and easy to integrate around the clock.
2. Market and technical pain points
The screen content cannot be recognized under direct sunlight, and the user operation experience is poor
The screen is prone to aging or failure in environments with large temperature differences and high humidity
The screen generates a lot of heat when running at high brightness, affecting the heat dissipation design of the whole machine
Complex integration, compact structure space, and limited installation
3. Solution Overview
This solution uses a 21.5-inch full HD high-brightness LCD screen, combined with direct-down LED backlight, anti-reflective coating, high-strength structural design, and optional industrial-grade capacitive touch function, with excellent outdoor display performance and system compatibility. The screen is suitable for various outdoor self-service lockers, smart express lockers, storage terminals and other scenarios.
