About this item
This 4.0-inch transmissive TFT LCD display offers a sharp 720x720 RGB resolution, providing clear, high-quality visuals in a compact, square format. With a luminance of 260 cd/m², it performs well in typical indoor lighting environments, offering good visibility without excessive power draw.
The display has a wide operating temperature range of -20°C to +70°C and can be safely stored in temperatures between -30°C and +80°C, making it robust enough for various industrial, automotive, or outdoor applications where temperature fluctuations are common.
It features a 262K color depth, allowing for a broad spectrum of color reproduction, and utilizes the ST7703 driving IC for optimal performance. The active area of 101.52mm x 101.52mm ensures the screen is used efficiently, while the overall outline dimension of 105.60mm x 109.87mm x 2.2mm makes it suitable for applications with space constraints.
While it consumes 5600mW of power, the display's LED backlight is rated for 35,000 hours of use, ensuring long-term durability. The square format could be particularly useful for specialized applications that require a non-traditional aspect ratio. It would work well in wearables, embedded systems, or devices where the screen's unique shape offers design flexibility.
The wide viewing angle (ALL O’clock) means the display can be viewed from virtually any angle without distortion, making it a solid option for projects that require versatile viewing.
