Product Introduction

The CH400WV17B-CTBA is a 3.95-inch square touchscreen display module developed by Shenzhen Chenghao Optoelectronics Co., Ltd., featuring a 480*480 resolution IPS TFT LCD panel with a full-black effect. In terms of display performance, the 3.95-inch square IPS LCD panel offers excellent visual quality and supports free viewing angles. Its 480×480 pixel resolution (corresponding to a 480×3(RGB)×480 pixel dot matrix arrangement) ensures clear presentation of text, icons, and real-time data. A prominent feature of the CH400WV17B-CTBA is its integrated touch glass cover with a full-black finish, constructed using a G+G (glass + glass) structure. The "full-black effect" is a major highlight in both aesthetics and functionality: when the screen is off, the integrated black design blends perfectly with the device's casing; when lit, it enhances the contrast between content and background, thereby improving the overall user experience. The module's total thickness (including all components) is a maximum of 5.70 mm, with the TFT LCM (liquid crystal module) itself measuring 2.0 ± 0.2 mm. Environmental adaptability further enhances the module's practicality. It can operate stably within a temperature range of -20°C to +70°C, complies with RoHS environmental standards, and meets the requirements for sustainable production and use globally.

Product Features

  •  3.95-Inch Square IPS Display with 480×480 Resolution & All-Black Effect

    This module is equipped with a 3.95-inch square display area (matching its "square touch screen" positioning) and a 480×480 resolution (dot arrangement: 480×3(RGB)×480 dots), ensuring sharp rendering of text, icons, and real-time data . Its IPS technology provides 80/80/80/80 all-around viewing angles, eliminating color distortion even when viewed from extreme upper, lower, left, or right positions, while a typical luminance of 300 cd/m² guarantees clear visibility in both bright and dim environments. The all-black effect further enhances usability: when the display is off, it blends seamlessly with device enclosures; when lit, it boosts content contrast, balancing aesthetics and practicality.

  • Integrated All-Black Glass Cover with G+G Structure for Durability

    The module adopts an integrated all-black glass cover based on a G+G (Glass + Glass) structure, consisting of a 1.1mm-thick glass lens (for external protection) and a 0.55mm glass sensor (for touch signal capture), ensuring solid structural stability. The glass cover has a surface hardness of 6H, which effectively resists scratches from daily handling or small tools, and a transmittance of ≥82%, minimizing light loss to maintain the display’s brightness and color accuracy, thus extending the module’s service life .

  • Responsive Touch Function with Wide Voltage Adaptability

    The module’s touch function supports smooth and precise operation, and its working voltage range of 2.8V-3.3V is compatible with the common power supply configurations of embedded systems, avoiding the need for additional voltage conversion modules and simplifying integration into end devices . Paired with the square display area, the touch function enables intuitive user interaction—such as clicking icons or sliding to switch interfaces—making it suitable for scenarios requiring frequent human-machine interaction, like smart meters and industrial control panels.
