Product Introduction

The CH390WQ01A is a highly specialized display module designed by Shenzhen Chenghao Optoelectronics Co., Ltd. specifically for small-space applications. In terms of display performance, the CH390WQ01A's highlight is its 3.9-inch IPS LCD panel, supporting a full viewing angle of 80/80/80/80° and a resolution of 480×128 pixels. The module's backlight system has been optimized to balance performance and lifespan. The backlight is provided by 10 white LEDs, with a typical brightness of 300 cd/m² (minimum 260 cd/m²) and backlight uniformity exceeding 80%, ensuring consistent brightness across the entire long display area and preventing dark spots at the edges from obscuring critical data. Environmental adaptability and reliability are core design considerations for the CH390WQ01A. It can operate stably in a temperature range of -20°C to +70°C and can be safely stored in a temperature range of -30°C to +80°C, and can withstand extreme environments such as cold industrial warehouses in winter or hot vehicle cabs in summer.

Product Features

  • 3.9-Inch Long-Strip IPS Panel with 480×128 Resolution & 80/80/80/80 All-Viewing Angles

    This module adopts a 3.9-inch long-strip IPS TFT panel (non-square/widescreen/round) with a resolution of 480×128 pixels (dot arrangement: 480(RGB)×128 dots) and a dot pitch of 0.198(W)×0.198(H) mm, ensuring sharp rendering of text, real-time data, and simple icons. Its IPS/Transmission/Normally Black display mode and 80/80/80/80 all-around viewing angles eliminate color distortion and detail loss from extreme off-angles, making it suitable for multi-user monitoring or devices mounted in special orientations.

  • Wide Temperature Range for Harsh Environment Adaptability

    The module operates stably within a temperature range of -20°C~+70°C and tolerates storage temperatures of -30°C~+80°C, withstanding extreme conditions like cold industrial warehouses, hot vehicle cabins, and outdoor auxiliary equipment. This environmental resilience meets the reliability demands of professional applications requiring long-term stable operation in variable climates.

  • Rigorous Reliability & Long-Lifespan Backlight

    It undergoes strict reliability tests, including high-temperature storage (80°C±2°C for 96 hours), low-temperature storage (-30°C±2°C for 96 hours), vibration tests (1.5mm amplitude, X/Y/Z directions for 3 hours), and ESD tests (±8KV air mode, 10 cycles), ensuring resistance to defects like screen flicker or structural damage. The LED backlight also has a lifespan of 30,000 hours, minimizing maintenance costs for long-term deployed devices.
