In our daily life, most LCD products are square or rectangular, while relatively speaking, circular screens are relatively few. However, in recent years, with the change of people&#;s aesthetics and the emergence of various personal customization needs, circular LCD screens are also increasingly used in various fields, such as smart watches, smart wall clocks, electric vehicle instruments, automobile display instruments and so on.

In the market, there are mainly small-scale application scenarios, and different applications require different displays. So how to choose a screen suitable for your own product is particularly important. Next, I will briefly introduce the existing circular screens on the market that are already in mass production, their characteristics, the use of terminals and the existing problems of circular screens

Description

In fact, the display principle of the round LCD display is the same as that of the conventional rectangular and square LCD screens. Only through the production technology of the LCD glass and the adjustment of the screen parameters, the circular LCD screen can display normally in the circular state. The key factor that plays a decisive role is the design and formulation of the drive scheme, which is how to build a good bridge between the circular LCD screen and the motherboard.

Terminal Application

Round LCD displays are divided into large size and small size. Small round LCD screen is more widely used, such as smart wear, smart watch, smart wall clock, electric vehicle instrument, car display instrument, smart home appliances, smart handheld devices, etc. Large size circular screens are also used, generally more than 20 inches in size, such as new medical equipment, industrial equipment central control, museum exhibition halls, enterprise conference rooms, financial media centers, commercial venues, etc. See the following example diagram.

The display size is relatively small. The commonly used ones are 1.28inch/ 1.3inch, 1.45inch, 1.6inch, 2.1inch, 2.5inch, 2.8inch, 3.4inch, 4.0inch, etc. All features as below:

Existing problems of the round screen

1. Yield problem. Generally, the defect rate of round LCDs is a little bit higher than rectangle and square LCD screens. With the progress of technology, the yield is the same as that of ordinary screens.
2. Price. Normally, the price of round LCDs is higher than normal displays. But for small round LCDs like 1.28inch, the unit sample price is the same as 1.3inch square displays.
3. The circular LCD screen also has its own common faults, such as the display screen is not full around the arc, or the arc is white.
4. Round displays also have their advantages. For example, it has a wide viewing angle, low power consumption, a long lifetime, a good appearance&#;ect.

Customers need to choose the right round screen. Everyone has different requirements for the round screen and their main points. I hope everyone can find a display suitable for their own projects.
