4.3-inch Industrial-grade TFT LCD Display Module 800×480 Resolution 80-degree Viewing Angle

Product Description:

The CH430WQ22A-CT is a high-performance 4.3-inch landscape TFT LCD display module integrated with capacitive touch functionality, engineered for industrial and professional applications. Boasting a crisp 800x480 resolution, it delivers vivid 16M-color visuals with an 800:1 contrast ratio and 800 cd/m² high brightness (supports 300~1500 cd/m² customization). Adopting IPS transmissive normally black technology, it offers 80/80/80/80 all-angle viewing, ensuring clear visibility from any orientation.
		The module features a 24-pin FPC interface, supporting SPI as standard with customizable options including MCU, RGB, LVDS, and HDMI. Its compact dimensions (105.567.24.75 mm) with an active area of 95.04*53.86 mm make it ideal for space-constrained devices. Equipped with IIC interface capacitive touch (resistive or non-touch optional), it operates stably in -20~+70℃ temperature range, with storage temperature reaching -30~+80℃, suitable for harsh industrial environments.

Features:

• Ultra-Wide Viewing Angle IPS Panel
  The IPS transmissive normally black display provides uniform 80° viewing in all four directions, eliminating color distortion and ensuring consistent visibility for collaborative industrial operations.

• High Brightness & Customizable Luminance
  With 800 cd/m² standard brightness and 300~1500 cd/m² customization range, the module maintains clear readability even under strong ambient light, ideal for outdoor or high-glare industrial sites.

• Flexible Interface Compatibility
  Supports SPI as default, with expandable options including MCU, RGB, LVDS, and HDMI. The 24-pin FPC design ensures stable signal transmission for diverse industrial control systems.

• Broad Temperature Tolerance
  Operating temperature from -20℃ to 70℃ and storage temperature from -30℃ to 80℃ enables reliable performance in extreme environments such as outdoor monitoring and industrial automation equipment.

• Dual Touch Options with Precise Response
  Capacitive touch (IIC interface) as standard, with resistive touch or non-touch alternatives available, catering to different operational needs like glove-touch scenarios in factories.
