Analysis of the advantages and disadvantages of each display screen of the scales

LCD screen

Using liquid crystal display technology, content is displayed by changing the light transmittance of liquid crystal molecules under the action of an electric field.

Advantages: 1. The digital display effect is good and clear and easy to read; 2. Low energy consumption, effectively extending the battery life; 3. The viewing angle is wide, and the display can still be clearly displayed from different angles.

Disadvantages: 1. It can only display numbers and basic text, but cannot present images and complex information. 2. The color performance is relatively single, and only one color can be displayed.

LED screen

Use light-emitting diodes (LED lamp beads) as display elements to display numbers and graphics by emitting light

Advantages: 1. High brightness, can display clearly even in bright environment. 2. Stable display and high reliability. 3. The response speed is fast and suitable for displaying dynamic content.

Disadvantages: 1. It can only display numbers and basic graphics, and cannot present complex images and text. 2. The color performance is relatively single, and usually only one color can be displayed.

VA screen

It is a type of LCD. In the scale industry, color screen printing is usually added to achieve multi-color display.

Advantages: 1. High contrast and good display effect. 2. Wide viewing angle, can still be displayed clearly from different angles. 3. Able to display rich colors.

Disadvantages: 1. Relatively high energy consumption has a certain impact on battery life; 2. The more colors displayed, the higher the cost.

TFT screen

Thin film transistors control the on and off of liquid crystal molecules to display images and text.

Advantages: 1. The display effect is good, delicate and colorful. 2. Wide viewing angle, not limited by angle. 3. Interactivity can be achieved without being subject to screen-level color restrictions. 4. Can display complex content such as images and videos.

Disadvantages: 1. Relatively high energy consumption has a certain impact on battery life. 2. It needs to be equipped with high-end driver chips and the cost is relatively high.
