Product Introduction

The CH350HV37A from Shenzhen Chenghao Optoelectronics Co., Ltd. is a 3.5-inch TN TFT LCD module with 320×480 resolution and a 50-pin interface supporting SPI, MCU (8/9/16/18-bit 8080-series), and RGB (16/18-bit) protocols—enabling seamless integration with diverse industrial and embedded systems. Built on TN/Transmissive/Normally White technology with a 6 o’clock viewing direction, it delivers clear, stable visuals ideal for real-time data display in control panels and portable test equipment. The active area measures 48.96 (W) × 73.44 (H) mm, within a compact module size of 56.54 × 84.96 × 2.4 mm. Backlighting uses 6 parallel white LEDs (VF = 3.2V, IF = 120mA), providing 300 cd/m² typical brightness for readability in both well-lit workshops and dim indoor settings. The module operates reliably from –20°C to +70°C and withstands storage temperatures of –30°C to +80°C. It has passed rigorous reliability tests including high/low-temperature storage (±2°C for 96 hours), thermal cycling, vibration (10–55 Hz, 3 hours per axis), and ESD (±8 kV air discharge, 10 times), ensuring long-term durability in demanding environments. Its multi-interface flexibility, robust mechanical design, and stable display performance make the CH350HV37A an optimal solution for industrial control systems, embedded terminals, and professional handheld instruments.

Product Features

  • 3.5" 320×480 Video Display
    This module uses a 3.5-inch TN TFT panel with a non-square/elongated/widescreen design, operating in TN/transmissive/normal white mode. Its resolution is 320×(RGB)×480 pixels, and it has a precisely calibrated effective display area of ​​48.96(W)×73.44(H) mm, ensuring clear text, icons, and real-time data display in industrial or portable device scenarios.
  • Supports SPI/MCU/RGB Multi-Interface Interfaces
    As a 50-pin module, it supports multiple interface protocols, including 8-/9-/16-/18-bit 8080 system interfaces, 4-wire_8-bit/3-wire_9-bit SPI, and 16-/18-bit RGB interfaces. This versatility eliminates compatibility barriers with different microcontrollers (MCUs) and embedded systems, simplifies wiring, and accelerates integration into industrial control or embedded devices.
  • 300cd/m² Standard Backlight Brightness
    Powered by six parallel white LEDs (electrical parameters: VF=3.2V, IF=120mA), this module provides a typical backlight brightness of 300 cd/m². This ensures clear visibility in both bright industrial workshops and moderately dim indoor environments, avoiding visual blurring caused by insufficient light.
