4.0-inch 480x800 semi-transmissive and semi-reflective TFT display/RGB interface/ultra-low power sunlight-visible display/ST7701 controller/STM32/RK series

This standard 4.0-inch display TFT-H040A30WVIST1N40 has a resolution of 480x800 pixels and an IPS full-viewing display. It has excellent viewing effects no matter from which direction. Generally speaking, traditional LCD displays are either fully transparent with polarizers, which allows backlight to pass through, and the content of the display can only be seen under the action of backlight, or fully reflective, which means that no backlight is required, and the content of the display can be observed under the reflection of natural light. However, both fully transparent and fully reflective have their own advantages and disadvantages, so we have developed this new product that can combine the two types to achieve low power consumption, use backlight to read the display in dark conditions, and eliminate backlight in natural light conditions, so that the content of the display can be read through reflection. The brightness is 100cd/m2. Although the brightness of this display is very low, due to its semi-transmissive and semi-reflective characteristics, it can be exempted from the use of backlight in natural light environments, and the display content can be read through the backlight under the condition of no ambient light. The semi-transmissive and semi-reflective characteristics of this product make it ultra-low power consumption and perfect visibility in sunlight, making it the preferred display for outdoor products.

Connection method: It uses 30PIN FPC soft cable connection to provide safe and reliable electrical connection. The connection method of FPC soft cable makes disassembly easier and easier to operate. This TFT LCD display is powered by the ST7701 controller. The controller optimizes the functions of the display to ensure smooth operation and accurate presentation of images and graphics. The RGB interface enables fast and efficient communication between STM32/RK motherboards, ensuring smooth data transmission and real-time updates. Our displays are all RoHS-compliant and comply with strict environmental and safety standards.
