3.5 Inch 320×480 Transflective TFT Display
3.5 Inch 320*480 Transflective TFT Display combines reflective and transmissive display technology for outdoor applications, it delivers razor-sharp images in direct sunlight while maintaining exceptional power efficiency.
-
☀️ Unbeatable Sunlight Visibility: Powered by transflective technology, the display brightness increases with the ambient light (Brightness = 150 nits + 12% Ambient Light Reflection). It solves the “washout” issue common in standard screens—the brighter the sun, the clearer the image
-
🔋 Ultra-Low Power Consumption: Break the curse of “power-hungry displays.” In bright outdoor conditions, the backlight can be dimmed or turned off completely, relying solely on reflected natural light. This significantly extends the battery life of handheld devices.
-
🛠️ Easy Integration (MCU/SPI): Features an MCU (8/16-bit) and SPI interface, making it compatible with low-cost microcontrollers (like STM32, ESP32). No need for expensive high-end processors, effectively lowering your BOM costs.
-
🌡️ Industrial Grade Quality: Engineered for harsh environments, this display features a wide operating temperature range (-20°C to +70°C) and has passed a rigorous 240 hours reliability test to ensure rock-solid stability. The multi-point projected capacitive (PCAP) touch screen supports both glove and wet touch, delivering a silky-smooth user experience across all application scenarios.
Transflective TFT Work Principle
-
Core Structure: Half Window, Half Mirror
In Transflective Display, the microscopic structure of each individual pixel is physically divided into two distinct zones: Transmissive Area (This part is transparent, allowing the backlight to pass through like a window) and Reflective Area:(The bottom of this section is coated with a high-reflectivity metal film, acting like a tiny mirror).This unique “Half Window, Half Mirror” structure is the physical foundation that allows the display to adapt perfectly to all lighting environments.
-
Working Modes: Adapting to Ambient Light
- Outdoor Bright Light: Reflective Mode on; Utilizes sunlight or strong ambient light and the backlight can be turned off completely to achieve low power consumption.
- Indoor/Dark Environment: Transmissive Mode on, Utilizes the screen’s built-in LED backlight.
- Semi-Bright Environment: In conditions such as cloudy days or indoor offices, both the Transmissive and Reflective areas work simultaneously. The backlight and ambient light combine to ensure optimal screen visibility and contrast.
Explore Application Scenarios
Crystal Clear Visibility Under Direct Sun
- Walkie-talkie: Delivers crystal-clear channel and GPS data in direct sunlight, eliminating the need for hand shielding. The reflective mode significantly reduces power drain, ensuring reliable communication throughout long outdoor shifts.
- Bike Computer: Provides a glare-free, paper-like view of navigation maps and speed metrics under the midday sun. Ultra-low energy consumption supports marathon rides without battery anxiety, keeping data visible all day.
- Portable Fish Finder: Seamlessly combats strong water surface reflections with high-contrast visibility. The display renders underwater topography and fish targets with sharp detail, ensuring clarity even in blindingly bright marine environments.
Power Saving, Do More
- Compared to standard High Brightness TFTs, how much battery power can this display actually save?
A: The energy savings are substantial. To fight against sunlight, standard High Brightness TFTs must ramp up their backlight to over 1000 nits, which is the biggest power drain and heat source in a device. With this Transflective display, the brighter the sun, the more you can dim or completely turn off the backlight. In typical daytime outdoor scenarios, power consumption can be reduced by 80% compared to a full-brightness IPS screen.
