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.
