TFT LCD screens are now widely used in various fields, covering every corner of our daily life. We all know that some LCD screens are large in size, such as tablet computers and home appliances, and some are relatively small in size, such as handheld devices and smart wearables. Then let's analyze from the perspective of LCD screen size, and briefly introduce the application fields of LCD screens of various sizes.

Industrial handheld devices: such as infrared ranging, infrared thermal imaging cameras, temperature measurement, noise measurement, etc., the size of the LCD screen is between 2.0 inches and 5.0 inches. This type of equipment requires the screen to be visible in the sun. wide operating temperature.

ATM/POS machine: products that charge by swiping cards and scanning. The size of the LCD screen is 3.5 to 5.0 inches, and the screen is required to have a high-definition touch screen.

Car gauge LCD screen: used in car instrumentation, car central control, the size of the LCD screen is 7.0 inches to 10.1 inches, the car gauge screen requires capacitive multi-touch, has ultra-wide operating temperature, shock resistance, ultra-wide viewing angle, LCD screen with high brightness and high definition.

Industrial equipment: such as small processing equipment, numerical control equipment, etc., the size of the LCD screen is 7.0 inches to 10.1 inches, and the screen is required to be touch-sensitive, shock-resistant, impact-resistant, and stable.

Medium-sized medical equipment: such as syringe pumps, ECG monitors, fetal heart rate monitors, ventilators, etc., the size of the LCD screen is 7.0 inches to 10.1 inches, and the screen is required to have an ultra-wide viewing angle and a long lifespan.

Home medical products: blood pressure meters, blood glucose meters, thermometers, etc., the size of the LCD screen is 2.8 inches to 5.0 inches, requiring the screen to be impact-resistant and have a wide viewing angle.

Instruments and meters: oscilloscope, optical time domain, optical cable survey, smart scale, etc., the size of the LCD screen is 3.5 to 7.0 inches, and the viewing angle of the screen is required to be wide.

Industrial tablet equipment: man-machine interface, outdoor handheld tablet, etc., the size of the LCD screen is 7.0 to 10.1 inches, and the LCD screen is required to have high resolution, shock resistance, and impact resistance.

LCD screen application field Smart home: smart switch panel, air conditioner panel, background music wall host, etc., the size of the LCD screen is 3.5 to 7.0 inches, and the screen is required to have an ultra-wide viewing angle and a long life.

Nautical equipment: GPS navigator, console instrument, etc., the size of the LCD screen is 7.0 to 10.1 inches, and the screen is required to have an ultra-wide operating temperature, be visible in the sun, and have a long life.

Household appliances: white goods, kitchen appliances, etc., the size of the LCD screen is 3.5 to 10.1 inches, and the LCD screen is required to have a wide viewing angle and a long life.

Elevator equipment: floor panel, elevator inner panel, LCD screen size is 4.3 to 8.0 inches, and the LCD screen is required to have a wide viewing angle and a long life.

LCD circular liquid crystal screen - as the name implies, it is a round liquid crystal screen. Most of the LCD screen products we usually come into contact with are square or rectangular, and there are relatively few circular screens. But in recent years, with the change of people's aesthetics, more and more circular LCD screens have been used in various fields, such as smart watches, smart wall clocks, electric vehicle meters, car display meters and so on. Usually it is a relatively small size application scenario. Next, let us introduce the LCD circular LCD screen in detail.

Brief introduction of LCD circular LCD screen

In fact, the display principle of the LCD circular liquid crystal screen is the same as that of the conventional rectangular liquid crystal screen, but through the production technology of the liquid crystal glass and the adjustment of the screen parameters, the circular screen can display normally even in the circular state. The key to the decisive factor is the design and formulation of the drive scheme, that is, how to establish a good bridge between the circular LCD screen and the motherboard. Circular LCD screens are basically used on smart devices, and they pay more attention to the driving scheme and UI interface design scheme. Therefore, the circular LCD screen is actually an innovative, intelligent, and high-end LCD product. The display size is relatively small, commonly used are 2.1 inches, 2.36 inches, 3.4 inches, 6.2 inches and so on. Circular LCD screens also have their own unique common faults, such as dissatisfaction around the arc of the display screen, or white light around the arc.

LCD circular liquid crystal screens are divided into large size and small size. Small size circular screens are more widely used, such as smart wear, smart watch, smart wall clock, electric vehicle instrument, car display instrument, smart home appliance, smart handheld device and so on. Large-size circular screens are also used, and the general size is more than 20 inches, such as new medical equipment, industrial equipment central control, museum exhibition halls, corporate meeting rooms, financial media centers, commercial places, etc. Please see the example diagram below.
