About this item
This 2.8-inch transmissive TFT LCD display offers a resolution of 480x480 pixels (RGB arrangement), providing clear and detailed visuals. Despite not having touchscreen functionality, its vibrant display is suitable for projects where interaction is handled through external buttons or other input methods. The display's active area is 70.13 x 70.13 mm, with a slightly larger viewing area of 71.13 x 71.13 mm, which gives a good proportion of usable screen space.
The screen is powered by the ST7701SN-G5-1 driving IC, and it features a standard backlight made up of four LEDs, ensuring decent visibility with a luminance of 350 cd/m². While it doesn't have the highest brightness compared to some other modules, it is still well-suited for most indoor applications. With a contrast ratio of 1200:1, the screen offers good color differentiation and clarity.
It operates within a temperature range of -10°C to 60°C, which makes it more appropriate for general indoor environments rather than extreme conditions. The storage temperature range is slightly wider, -20°C to 70°C, allowing for better handling of temperature fluctuations during storage or transport.
The module consumes 280 mW of power, making it suitable for low-power applications, and its LED backlight has a lifespan of up to 35,000 hours, ensuring long-term durability. The customizable cover glass gives flexibility for product design.
This screen would be a good fit for applications like display panels, monitoring systems, or embedded devices where a larger screen and higher resolution are required, but touch interaction is not needed.
