The main technical parameters of LED display specifications include resolution, pixel pitch, brightness, contrast, color saturation, refresh rate, viewing angle, power consumption, reliability, waterproof level, response time, and installation method.
LED display (Light Emitting Diode Display Screen) is a device that displays images and texts through LED as a light-emitting element.
It has high brightness, contrast and color saturation and is suitable for indoor and outdoor environments.
The following is a detailed introduction to the technical parameters of LED display specifications:
1. Resolution: Resolution refers to the ability of the display to present image details. It is usually expressed in pixel units, such as 1920×1080 for horizontal and vertical pixel numbers. Higher resolution can provide clearer and more delicate images.
2. Pixel pitch: Pixel pitch refers to the distance between adjacent pixels. Smaller pixel pitch can provide higher pixel density, resulting in clearer and more delicate images, but it also increases costs.
3. Brightness: Brightness refers to the luminous intensity of the LED display. It is usually expressed in nits. Higher brightness can improve the visibility of the display in bright environments.
4. Contrast: Contrast refers to the measure of the difference in brightness between different areas on the display. Higher contrast ratios provide more distinct images and better color performance.
5. Color saturation: Color saturation refers to the vividness of the colors that an LED display can present. Higher color saturation can provide more vivid and realistic images.
6. Refresh rate: The refresh rate refers to the number of times the display updates the image per second. It is usually expressed in Hertz (Hz). Higher refresh rates can provide smoother images, especially in fast-moving scenes.
7. Viewing angle: Viewing angle refers to the visibility of the image when the display is viewed from different angles. It is usually expressed in horizontal and vertical angles. A larger viewing angle range ensures that the audience can clearly see the content on the display from different positions.
8. Power consumption: Power consumption refers to the energy consumed by the display when it is running. Lower power consumption can save energy and reduce operating costs.
9. Reliability: Reliability refers to the stability and durability of the display under long-term operation. High-quality LED displays should have a long life and stable performance.
10. Waterproof level: Waterproof level refers to the display's ability to protect against water. Outdoor LED displays usually need to have a certain degree of waterproofness to enable them to operate normally in various weather conditions.
11. Response time: Response time refers to the speed at which the display switches images. Faster response time can reduce image blur and afterimages, especially suitable for playing fast videos and animations.
12. Installation method: LED display screens can be installed in various ways, including fixed installation, hanging installation and ground installation.
Different installation methods are suitable for different application scenarios and space constraints.
In summary, these technical parameters are important indicators for evaluating the performance and applicability of LED display screens.
Understanding these parameters can help users choose LED display screens that suit their needs.
