The side-lit LED (Edge-lit) design is a key feature of this monitor, offering:
Slim & Lightweight Design: Allows the monitor to maintain a compact, open-frame structure without sacrificing display area.
Uniform Brightness Distribution: Advanced light guide technology ensures consistent illumination across the entire screen.
Energy Efficiency: Side-lit backlight consumes less power than traditional direct-lit solutions, reducing operational costs.
Low Heat Emission: Active heat dissipation and intelligent temperature control maintain stable performance even under continuous outdoor operation.
Industrial Durability: Suitable for harsh environments, including outdoor kiosks, passenger information displays, and EV charging stations.
With edge-lit backlight, the 21.5” open frame monitor achieves high brightness, sunlight readability, and a slim, industrial-grade design, making it ideal for outdoor digital signage and interactive applications.
