In our daily lives, most LCD products tend to be square or rectangular. However, circular displays are gaining popularity due to evolving aesthetics and a rise in personal customization options. Now, circular LCD screens are becoming common in diverse applications such as smartwatches, digital wall clocks, electric vehicle dashboards, and vehicle instrumentation displays.

The market predominantly features small-scale applications, and since different uses necessitate distinct displays, selecting the right screen for your product is crucial. This article will introduce the various circular displays currently in mass production, detailing their features, applications, and the challenges they face.

Understanding Round Displays

The working principle of circular LCD displays mirrors that of traditional rectangular or square screens. By adjusting the production techniques for the LCD glass and fine-tuning screen parameters, round LCD panels can effectively operate in a circular format. A critical aspect influencing performance is the design of the driver scheme, which connects the circular LCD screen to the motherboard.

Applications of Circular Displays

Circular LCD screens can be categorized into large and small sizes. The smaller screens find extensive use in smart wearables, smartwatches, wall clocks, electric vehicle dashboards, car display units, and smart home appliances. In contrast, large circular displays, typically over 20 inches, are used in new medical devices, industrial control systems, exhibition halls, conference rooms, media centers, and commercial venues.

Featured Characteristics of Round Displays

The circular displays come in various sizes, commonly ranging from 0.71 inch to 4.0 inches. Below are some notable specifications:

• 0.71 inch: Resolution: 160*160, Brightness: 350 cd/m²
• 1.28 inch: Resolution: 240*240, Brightness: 420 cd/m²
• 2.1 inch: Resolution: 480*480, Brightness: 300 cd/m²
• 4.0 inch: Resolution: 720*720, Brightness: 300 cd/m²

Challenges Faced by Round LCD Screens

1. Yield Issues: The defect rate for circular LCDs is often higher compared to their rectangular counterparts. However, with advancing technology, these yield rates have improved.
2. Pricing: Circular LCDs usually carry a higher price tag, although smaller sizes like 1.28 inches can have similar costs to 1.3-inch square displays.
3. Common Defects: Round displays may experience certain faults, such as incomplete display coverage around the arc or white arcs on the screen.
4. Advantages: Round displays boast wide viewing angles, low power consumption, extended lifespans, and appealing aesthetics.

When selecting the right round screen, it is essential to consider individual requirements and expectations for your project.

Tips for Choosing the Right TFT LCD Display

As a project manager, here are several factors to consider when selecting a TFT LCD display:

1. Display Size

Evaluate the display size in relation to the overall device size and viewing distance.

2. Resolution

Select a resolution that complements the display size and intended use, ensuring clear image quality.

3. Viewing Angle

Assess the required viewing angles based on expected conditions.

4. Brightness

Choose brightness appropriate for device use and viewing conditions.

5. Touchscreen Capability

If touch input is necessary, opt for displays with integrated touchscreen features.

6. Interface Compatibility

Ensure the display interface is compatible with the device's hardware and software requirements.

7. Power Consumption

Consider power needs, especially for battery-operated devices.

8. Operating Temperature

Ensure the selected display can operate effectively in its intended temperature range.

9. Pricing

Weigh the display's cost against budget constraints and project needs.

10. Manufacturer Reputation

Choose a renowned manufacturer with a history of quality. ORIC Electronics is committed to providing high-value products globally.
