5 basic knowledge of LED transparent screens

1. What is contrast?

Under certain ambient illumination, the ratio of the maximum brightness of the LED transparent screen to the background brightness.

2. What is refresh frequency?

The number of times the screen is repeatedly displayed by the transparent screen in unit time.

3. What is the best visual distance?

Is to be able to see the contents of the transparent screen just completely, without flat color, the image content of the clearest position relative to the vertical distance of the screen body.

4. What is perspective? What is viewable? What is the best perspective?

Angle of view refers to the Angle formed by two observation directions and normal directions on the same plane when the brightness of the observation direction drops to 1/2 of the normal brightness of the LED transparent screen, which can be divided into horizontal and vertical angles. However, Angle of view is just the direction of the image content on the transparent screen, which is formed by the Angle formed by the normal line of the transparent screen. The best Angle of view is to just see the content on the transparent screen without bias. Image content is the most clear direction with the normal Angle.

5. How to choose the right LED transparent screen?

1. The need to display content.

2. Confirmation of visual distance and perspective.

3. Screen resolution requirements.

4. Requirements for the installation environment.

5. Cost control.
