Feature: Displays
2. Optical bonding, anti-refl ective & anti-glare coatings While brightness helps, refl ections can still be a problem. Optical bonding and anti-refl ective coatings minimise glare and enhance contrast, further improving screen readability. Relec Electronics off er custom optical bonding solutions and specialised coatings to ensure maximum visibility, even in the brightest conditions. 3. Wide temperature tolerance Outdoor displays oſt en face extreme temperatures. A reliable outdoor TFT display should have an operational range between -30°C to 85°C, ensuring performance in both freezing cold and scorching heat. 4. IP-Rated waterproof & dustproof protection Many applications require displays to withstand moisture, dust and debris. IP65 or higher-rated displays provide rugged protection against the elements. 5. Wide viewing angles Many industrial displays use IPS (In-Plane Switching) technology, which provides 178° viewing angles and maintains colour accuracy, crucial for outdoor signage and kiosks.
Industry applications of high-brightness TFT displays 1. Outdoor kiosks & digital signage Public kiosks, ticket machines and advertising screens require sunlight-readable TFT displays to maintain visibility throughout the day, no matter the lighting conditions. 2. Marine & military navigation Harsh environments like open seas demand displays that can withstand salt, humidity and sunlight. High-brightness, waterproof TFT LCDs ensure clear readings for navigation and radar systems. 3. Industrial & factory automation Factories with bright overhead lighting need control panels that remain legible in high-glare conditions. Industrial TFT screens provide durability and clarity, reducing the risk of operational errors. 4. Medical equipment & outdoor healthcare devices Medical devices, whether used in ambulances or outdoor health stations, must always remain visible. High-brightness TFT screens ensure critical data is always readable.
Overcoming challenges in outdoor display technology
Screen durability & longevity Prolonged exposure to UV light can degrade displays over time. Using UV-resistant materials and rugged TFT panels extends screen life and prevents discoloration.
Touchscreen responsiveness in harsh conditions Capacitive touchscreens can be unresponsive with gloves or wet hands. Projected capacitive (PCAP) touch with glove and water resistance solves this issue for outdoor and industrial applications.
Choosing the right high-brightness TFT screen If your display needs to perform under the sun or in challenging environments, investing in a sunlight-readable TFT display is essential. Consider factors like brightness, anti-glare treatments, temperature tolerance and rugged design to ensure optimal performance.
