Breaking the Mold Exploring Chenghao Optoelectronic’s High-Performance

In today’s fast-evolving world of consumer electronics, industrial instrumentation, and smart devices, display technology continues to push boundaries beyond conventional rectangular formats. Among the most intriguing innovations in recent years is the round TFT display — a circular LCD solution that combines aesthetic elegance with functional versatility. Shenzhen ChengHao Optoelectronic Co., Ltd. (commonly known as Chenghao Display), a specialized manufacturer based in Bao’an, Shenzhen, has positioned itself as a key player in this niche with its dedicated Round TFT Display category.

This carefully curated product lineup showcases Chenghao’s expertise in delivering high-quality circular screens that break free from the limitations of traditional square or rectangular displays. With a strong emphasis on 360-degree omnidirectional visibility, customization capabilities, and reliable performance, these round TFT modules are rapidly gaining traction across multiple industries.

Why Round TFT Displays Are Gaining Popularity

Traditional rectangular screens, while practical, often impose design constraints. Edges create visual boundaries, and viewing angles can limit usability in certain orientations. Round TFT displays solve these issues elegantly. Their circular contour provides a natural, borderless viewing experience — information appears to float within a perfect circle, creating a more intuitive and premium feel.

The most significant technical advantage lies in the elimination of viewing angle restrictions. Many of Chenghao’s round displays utilize IPS (or IPS-like ADS) technology, delivering consistent 85°/85°/85°/85° viewing angles (contrast ratio >10). This means colors remain vivid and details stay sharp whether the user views the screen from directly in front, at an angle, or even from the side — a crucial benefit for applications like smart home controllers, automotive dashboards, wearable devices, and industrial gauges where mounting orientation varies.

Moreover, the circular form factor aligns perfectly with human visual perception. Our eyes naturally process circular patterns (think analog dials, clocks, speedometers, and even the iris of the eye), making round displays feel more organic and user-friendly for presenting radial information such as progress indicators, gauges, health metrics, or directional data.

Chenghao’s Round TFT Display Portfolio: Diversity in Size and Performance

Chenghao Optoelectronic currently features four carefully selected round TFT display models on their category page, covering a practical size range from compact wearables to larger control interfaces. Each model balances resolution, power efficiency, and integration flexibility.

1. 1.3 Inch 240×240 Round TFT Display This ultra-compact option is perfect for entry-level smart wearables. With a resolution of 240×240, it delivers crisp rendering of text, icons, and basic graphics within a tiny footprint. The small size makes it ideal for fitness trackers, miniature IoT sensors, and compact smartwatches where space is at a premium. Low power consumption and a simple interface design ensure seamless integration into battery-powered devices.
2. 1.32 Inch 360×360 Small TFT Screen (Model: CH132HV01A) Slightly larger yet still remarkably compact, this model steps up to 360×360 resolution — offering noticeably sharper detail for its size. It adopts a transmissive/negative polarizer mode with 300 cd/m² typical brightness and an SPI interface. Operating reliably from -20°C to +70°C (storage range -30°C to +80°C) and carrying RoHS compliance, this display suits mid-range smart wearables, portable instrumentation, and small smart home controllers. Its slim profile (approximately 37×33×2.5mm) enables elegant product designs without sacrificing performance.
3. 2.1 Inch 480×480 Round TFT Display Moving into medium-size territory, the 480×480 resolution provides excellent pixel density for clear visualization of data, icons, and simple UI elements. This size strikes an ideal balance — large enough for comfortable reading of metrics and information, yet compact enough for integration into space-constrained products. Applications frequently include industrial gauges, fitness equipment displays, smart thermostats, and health monitoring devices where dial-style presentation feels intuitive and professional.
4. 4 Inch 720×720 High-Resolution Round TFT Display (Model: CH400HD01A) The flagship offering in the current lineup, this 4-inch screen boasts an impressive 720×720 resolution (720×RGB×720 arrangement) — delivering true high-definition performance in a circular format. Built with premium ADS (advanced IPS-like) technology, it achieves wide 85° all-around viewing angles, 250 cd/m² brightness (with potential for higher customization), and supports dual SPI + RGB interfaces for flexible system integration. The module includes a slim structural design with protective FPC stiffener, making it suitable for more demanding applications such as premium smart home control panels, portable industrial monitors, electric vehicle dashboards, tricycles instrumentation, and even select automotive circular displays.

Across the portfolio, Chenghao emphasizes several common strengths:

• Support for rich 16.7M color depth
• Customizable brightness (up to 800 cd/m² in some configurations)
• Multiple interface options (SPI, MIPI, RGB, etc.)
• Wide operating temperature range (-20°C~+70°C typical)
• RoHS compliance for global market requirements
• Comprehensive customization services (resolution fine-tuning, FPC length/shape, touch integration, cover glass design)

Ideal Applications and Market Positioning

Chenghao’s round TFT displays target forward-thinking product designers and manufacturers who want to differentiate their devices through innovative form factors. Key application areas include:

• Smart Wearables — vintage-style smartwatches, fitness bands, and health trackers
• Smart Home — circular control panels for lighting, climate, and security systems
• Industrial & Instrumentation — modern digital gauges, portable testers, and panel meters
• Automotive & Mobility — electric scooters, tricycles, e-bikes, and emerging circular dashboard concepts
• IoT & Portable Devices — sensors, mini terminals, and handheld analyzers

The company’s emphasis on customization sets it apart. Whether a client needs a special FPC shape, higher brightness for outdoor visibility, integrated capacitive touch, or specific mounting holes, Chenghao provides tailored engineering support — a critical advantage in competitive product development cycles.
