Product Introduction

The CH400HD01A from Shenzhen Chenghao Optoelectronics Co., Ltd. is a customized display solution. Its unique 4-inch circular display area is a key design feature, distinguishing it from standard rectangular modules. This module boasts a 720x720 pixel resolution (dot matrix arrangement: 720xRGBx720) and supports a wide viewing angle of 85/85/85/85 (contrast ratio > 10), ensuring consistent color accuracy and clarity regardless of whether the user views it from above, below, left, or right. This eliminates the narrow viewing angle problem common in low-end displays, ensuring optimal performance for multi-user or multi-location use. The CH400HD01A has a standard design brightness of 250 cd/m², calibrated for stable operation in indoor environments (such as living rooms with smart thermostats or workshops with small tools) and moderate outdoor scenarios (such as IoT terminals in a shady garden).

The CH400HD01A features dual SPI and RGB interfaces, allowing for flexible integration with various microcontrollers and mainboards, thus expanding its application scenarios across industries. Whether it's a smart kitchen scale with a round panel for home use, a portable round pressure gauge for the workshop, or a motorcycle odometer with a round digital instrument, this module's 4-inch round design, high resolution, and stable performance provide a user-friendly and aesthetically pleasing solution.

Product Features

  • 4-inch Circular Display Area, User-Centric Design

This module features a unique 4-inch circular display area, a key difference from standard rectangular TFT modules. This circular design is optimized for devices requiring an intuitive, natural visual layout, such as circular smart thermostats, motorcycle digital odometers, and portable industrial instruments.

  • 720x720 High Resolution for Sharp Details

Equipped with a 720x720 pixel resolution (720xRGBx720 arrangement), this module delivers high-definition visual performance, ensuring even minute details are clearly displayed—crucial for applications where data accuracy and visual clarity are paramount.

  • 85/85/85/85° Wide Viewing Angle for Multi-Angle Use

Utilizing advanced display technology, this module offers an 85/85/85/85° viewing angle (measured at a contrast ratio >10). Unlike the narrow "optimal viewing area" of lower-end displays, this wide viewing angle performance supports multi-user scenarios.

  • Wide operating temperature range of -20°C to +70°C, suitable for various environments

This module maintains stable performance within an operating temperature range of -20°C to +70°C and supports storage temperatures from -30°C to +80°C. This wide temperature adaptability allows it to operate reliably in various un-air-conditioned environments, such as cold winter garages (suitable for motorcycles with digital odometers).
