The display unit board is composed of multiple LED lamp beads and is responsible for displaying images and text; the control system is responsible for controlling the on and off of the LED lamp beads to achieve effects such as image display and text scrolling.
- 유형:
LED taxi screens can be divided into single-primary, dual-primary, and three-primary color displays according to display color; they can be divided into graphic and text screens, synchronization screens, and market price displays according to display performance; they can be divided into indoor screens according to the use environment. , outdoor screen, and semi-outdoor screen.
- 이점:
LED taxi screens have the advantages of high brightness, long-distance visual effects, clear images, bright colors, good stability, low power consumption, high light efficiency, and long life, so they are widely used in advertising, information release, and traffic instructions. And other fields.
- 해결:
The resolution of an LED taxi screen refers to the number of pixels on the screen, usually expressed in terms of the number of horizontal pixels and the number of vertical pixels. The higher the resolution, the clearer the displayed image.

Therefore, when choosing an LED taxi screen, you need to choose an appropriate viewing angle based on the actual use environment and viewing distance.
- 명도:
The brightness of the LED taxi screen refers to the intensity of the screen’s light, usually expressed in candelas per square meter (cd/m²). The higher the brightness, the better the visibility of the screen under strong light, but too high a brightness may cause visual fatigue and discomfort.
2. Performance parameters and selection suggestions for LED taxi screens
When purchasing LED taxi screens, the key performance parameters that need to be paid attention to include brightness and viewing angle, resolution and pixel density, color performance and restoration, refresh rate, grayscale, etc.
Brightness and viewing angle determine the visual effect of LED taxi screens in outdoor environments. Generally speaking, the higher the brightness, the larger the viewing angle, and the better the display effect.
Resolution and pixel density affect the clarity and detail expression of the image. The higher the resolution, the greater the pixel density and the clearer the image.
Color performance and restoration determine the color display effect of LED taxi screens. Generally speaking, the brighter the color and the higher the restoration, the better the display effect.
When selecting a model, factors such as vehicle model suitability, operating environment, needs, budget, and return on investment also need to be considered. Different types of taxis have different requirements for the size and installation method of LED taxi screens, so the selection needs to be based on the actual vehicle type.
