Product Introduction

The CH400WV20A, developed by Shenzhen Chenghao Optoelectronics Co., Ltd., is a 4-inch TN LCD module. This module integrates TN (Twisted Nematic) display technology, efficient MIPI DSI signal transmission, and a robust hardware design, making it an ideal solution for applications such as automotive auxiliary screens, smart home control panels, and industrial auxiliary displays.

The CH400WV20A employs a TN/transmission/normal white display mode, with an optimal viewing angle of 6 0'clock and a screen contrast ratio of 500:1. The module has a resolution of 480×800 pixels (corresponding to a 480(RGB)×800 pixel dot matrix) and a dot pitch of 0.108 (width)×0.108 (height) mm, clearly displaying text, icons, and real-time data. This display uses 8 white LEDs with a standard brightness of 300 cd/m² (brightness adjustable from 300 to 1500 cd/m²), and backlight uniformity exceeding 80%, ensuring consistent brightness within an effective display area of ​​51.84 (width)×86.4 (height) mm. Furthermore, the LEDs have a lifespan of up to 20,000 hours and can operate stably in temperatures ranging from -10°C to +60°C, withstanding extreme environments such as frigid winter workshops or hot summer car interiors, reducing maintenance costs in long-term deployment scenarios (such as industrial control systems or intelligent thermostats).

Product Features

  • 4-Inch Vertical-Screen TN Panel with 480×800 Resolution & Optimized Active Area

    This module features a 4-inch vertical-screen design (aligning with its 480×800 pixel resolution, dot arrangement: 480(RGB)×800 dots) and an optimized active display area of 51.84(W)×86.4(H) mm, which perfectly fits narrow-space installations in portable devices or compact control panels . With a dot pitch of 0.108(W)×0.108(H) mm, it ensures sharp rendering of text, icons, and real-time data—critical for applications like in-vehicle auxiliary screens or smart home controllers that require clear vertical-screen information presentation.

  • Wide Temperature Range & Rigorous Reliability for Harsh Environments

    It operates stably within a temperature range of -10°C to +60°C and tolerates storage temperatures of -20°C to +70°C, withstanding extreme conditions like cold industrial workshops or hot summer vehicle cabins . Additionally, it passes rigorous reliability tests—including high-temperature storage (70°C±2°C for 96 hours), low-temperature storage (-20°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 .

  • Compact Slim Structure & Efficient 2-Lane MIPI DSI Interface

    With an overall size of 57.14(W)×96.85(H)×2.0(T) mm (slim 2.0mm thickness), the module’s compact profile allows seamless embedding into handheld devices or thin control panels without adding excessive bulk . Its 2-lane MIPI DSI interface supports high-speed, low-power signal transmission, compatible with most mainstream microcontrollers (MCUs) and embedded systems—eliminating the need for additional signal conversion modules and simplifying integration into end products.
