I. Basic elements
A 2.2-inch display is a type of liquid crystal display with a diagonal length of 2.2 inches, also known as a 2.2-inch LCD screen. It offers a variety of advantages, including high definition, high brightness, wide viewing angle, and fast response. This type of display is often used in smartphones, car navigation, smart home, industrial control, etc. The resolution of a 2.2-inch display is usually 320 x 240, with an aspect ratio of 4:3. It usually adopts wide-viewing-angle technology, such as IPS or VA, and therefore provides a wider viewing angle, allowing users to see a clear picture from different angles.
Second, the display technical parameters
The 2.2" display has the following specific technical parameters:
- Size: 2.2-inch diagonal length LCD display.
- Resolution: Common resolutions are 128×64, 192×64, 132×64, 240*320 and so on.
- Color: Grayscale display, some products support color configurations such as white on blue or black on white.
- Brightness: Brightness is usually between 300-500cd/m2, depending on the product model.
- Viewing Angle: Full viewing angle display allows users to view the screen content clearly from different angles.
- Material: TFT or IPS, etc.
- Touch mode: capacitive touch.
- Interface type: Common interface types include SPI interface, I2C interface, RGB interface, etc.
- Working temperature: generally 0℃ -+70℃.
- Storage temperature: -30℃ -+80℃.
These technical parameters make the 2.2-inch display suitable for a variety of portable products and smart wearable products, such as can be used as a smartphone auxiliary display screen to provide more information and entertainment functions.

Fourth, 2.2-inch display has the following advantages:
- Excellent display: the 2.2-inch display provides a clear, detailed image display, especially at high resolutions, and is capable of rendering more realistic colors and richer details.
- Fast response speed: 2.2-inch displays generally use advanced display technology to achieve faster response speed, making the screen smoother and reducing delays and drag phenomenon.
- Wide Viewing Angle: 2.2-inch displays generally use wide viewing angle technology such as IPS or VA, which can realize a wider viewing angle, enabling users to see clear images from different angles.
- Color Accuracy: 2.2-inch displays generally have high color gamut coverage and color accuracy, which can accurately reproduce the colors of images and videos and provide a better visual experience.
- High brightness: 2.2-inch displays generally have high brightness, which can provide better display effects under strong light and improve the visual experience.
- Small size and light weight: Because of their relatively small size, 2.2" displays usually have a small size and weight, making them easy to carry and use.
- Low power consumption: Due to the small size, the corresponding power consumption is low, which saves energy and power.
In short, 2.2-inch display has the advantages of excellent display effect, fast response speed, wide viewing angle, accurate color, high brightness and so on, which is widely used in various fields and brings convenience to people's life and work.
