Product Introduction

The CH350HV40A from Shenzhen Chenghao Optoelectronics Co., Ltd. is a 3.5-inch IPS TFT LCD module with 320×480 resolution and 50-pin interface, designed for industrial, medical, and automotive applications requiring high reliability and visual clarity. It features an IPS/Transmissive/Normally Black panel with 80°/80°/80°/80° wide viewing angles, eliminating off-angle distortion and ensuring consistent color and detail from any perspective. The active area measures 48.96(W) × 73.44(H) mm, with a 0.153 × 0.153 mm dot pitch for sharp rendering of text and graphics.
The module supports multiple interfaces via its 50-pin connector: 8/9/16/18-bit 8080 MCU, 4-line 8-bit / 3-line 9-bit SPI, and 16/18-bit RGB, enabling seamless integration with diverse embedded systems. Key pins include LEDA/LEDK (backlight), /RESET, DB[17:0] (data), and /CS (chip select).
Backlighting uses 6 parallel white LEDs (Vf = 2.9–3.5V, If = 120mA), delivering 300 cd/m² typical brightness and >80% uniformity, with a 20,000-hour lifespan for low-maintenance operation in both bright workshops and dim indoor settings.
Mechanically compact at 56.54 × 84.96 × 2.4 mm, it fits space-constrained enclosures. It operates from –20°C to +70°C and survives storage temperatures of –30°C to +80°C. Validated by rigorous tests—including 96-hour high/low-temperature storage, 3-hour tri-axis vibration (10–55 Hz), and ±8 kV ESD (air discharge)—it ensures long-term reliability in harsh environments. Cleaning with isopropyl or ethyl alcohol is recommended; anti-static precautions are required during handling.

Product Features

  • 3.5-Inch Vertical IPS Panel with 320×(RGB)×480 Resolution & 80/80/80/80 All-Viewing Angles

    This module adopts a vertical screen design (non-square/long strip/widescreen) with a 3.5-inch IPS panel, operating in Transmission/Normally Black mode. It features a resolution of 320×(RGB)×480 dots, a precisely calibrated active display area of 48.96(W)×73.44(H) mm, and 80/80/80/80 all-around viewing angles—ensuring uniform color accuracy, no off-angle distortion, and sharp rendering of text/icons for multi-user scenarios like industrial control panels.

  • 50-Pin Versatile Interface (8080 System/SPI/RGB) for MCU Compatibility

    As a 50-pin module, it supports multiple interface protocols: 8-/9-/16-/18-bit 8080 system interface, 4-lines_8bit/3-lines_9bit SPI, and 16-/18-bit RGB interface. This flexibility eliminates compatibility barriers with diverse microcontrollers (MCUs) and embedded systems, simplifying wiring and accelerating integration into industrial or medical devices.

  • Rigorous Reliability Testing for Durability

    The module undergoes strict reliability tests, including high-temperature storage (80℃±2℃×96hours), low-temperature storage (-30℃±2℃×96hours), vibration tests (X/Y/Z directions, 10Hz~55Hz~10Hz for 3hours), and ESD tests (±8KV air mode, 10 times)—ensuring no defects (e.g., air bubbles, non-display) in harsh professional environments.
