Outdoor rental screens with sun protection go beyond brightness to address long-term damage from ultraviolet (UV) radiation and extreme heat—two major threats to outdoor screens that can degrade components and shorten lifespan. Unlike basic outdoor screens (which may only resist water), sun-protected models integrate UV-resistant materials and heat-dissipation systems to maintain performance during prolonged sun exposure (e.g., all-day outdoor exhibitions, summer festivals).

UV protection focuses on preventing material aging: the screen’s front panel uses UV-stabilized PC (polycarbonate) or glass (with a UV-blocking coating) that filters 99% of UVA and UVB rays—this prevents yellowing of the panel (which distorts color) and degradation of internal components (e.g., LED wires, driver boards). The LED chips themselves are encapsulated in UV-resistant epoxy resin, ensuring their luminous efficiency doesn’t drop over time (non-protected chips may lose 10-15% brightness after 1,000 hours of sun exposure).

Heat protection is equally critical: outdoor screens exposed to direct sun can reach internal temperatures of 60-70°C, which damages LED chips and driver circuits. Sun-protected models use three heat-dissipation technologies: 1) aluminum backplanes (high thermal conductivity) to transfer heat from LEDs to the air; 2) built-in axial fans or heat sinks (for high-brightness models) to actively cool internal components; 3) light-colored frames (e.g., white or light gray) to reflect sunlight instead of absorbing heat. Some advanced screens also include temperature sensors that trigger a "low-power mode" if internal temperatures exceed 65°C, preventing overheating.

A rental company specializing in summer events reported that sun-protected outdoor screens retained 95% of their original brightness after 2,000 hours of use, compared to 80% for non-protected screens. For rental businesses, sun protection reduces maintenance costs (fewer component replacements) and extends the screen’s rental lifespan (3-5 years vs. 2-3 years for basic models). For event organizers, it ensures consistent performance even during the hottest, sunniest days—no content distortion or unexpected shutdowns.
