Eight Important Parameters to Distinguish Rental LED Display Screens Quality

rental LED display screens

In order to help the users to distinguish the quality of rental LED display screens quickly, the engineer of Glux Visual Effects Tech have analyzed the above eight aspects to help us. The first seven parameters are used for normal LED screens, the eighth one is suitable for small pixel LED screens.

1. Largest brightness of rental LED display screens;

It refers to the brightness of LED screens under some natural environmental light when the rental LED display screens are at highest gray level. As for outdoor use LED screens, there are different brightness requests according to different events. If the application environment brightness is high, then the brightness of LED screens will also be high.

2. Color temperature of rental LED display screens;

When we find that the picture color is different from the ideal color we want, it will be the picture distortion problem. This is relevant to the color temperature of the LED screen. If people watch the screen directly, 6500K to 8000K will be appropriate. If the LED screen is used for TV studio and played on a TV, then the color temperature only needs about 5500K.

3. Refresh rate of rental LED display screens;

Refresh rate refers to the times that the rental LED screens can wholly display the information in each second. If the refresh rate is low, there will be shake phenomenon on the screen when people watch it. Normally, human’s eyes have a refresh rate requests of 300Hz; if the refresh rate is lower than 300Hz, we may feel the video/picture shaking. Higher refresh rate can improve the brightness and color fidelity effects of the LED screens. We can use a camera to testify the refresh rate. If the refresh rate is high, the picture taken by the camera will be clear and with no scanning lines. This is an important parameters that should be considered if your event will be broadcasted on TV.

4. Wavelength of rental LED display screens;

The wavelength will determine the color purity and evenness of LED screen. You can ask the LED screen rental service provider to play the screen with all white color, and see if there is any variegated color. If you find the color looks a little red or blue, then the screen’s material, production technology and quality may have problem.

5. Electricity board design of rental LED display screens;

The electricity board is important to the working stability of rental LED screens. Basically, there are the following requests: firstly, choose higher quality PCB (normally 1.6 mm thickness, FR-4 glass fiber board); secondly, choose higher quality copper foil (it will influence the heat dissipation ability of the PCB, normally use 35 um(1OZ)). Basically, t is better to distinguish the quality of PCB by its weight (normally heavier one are with better quality).

6. Anti-statistic electricity measure of rental LED display screens;

Most LED screen rental companies will take measures to avoid statistic electricity from damaging the rental LED screens. Wearing statistic electricity cloth and dust-proof production department are the mostly used measures.

7. Evergy energy consumption of rental LED display screens;

There are two parameters to show the energy consumption of rental LED display screens: largest energy consumption and application energy consumption. You can ask your LED screen rental service provider to tell you the largest energy consumption or check it by yourself: check the number of power source at back of the screen, and calculate the largest power on each power source, then you can generally know the largest power consumption of the screen. The mostly use power source are 200W and 300W ones.

8. For small pixel LED screens: low brightness and high gray level of rental LED display screens;

About low brightness and high gray level, it refers that: when the brightness of small pixel rental LED display screens is controlled between 100cd/㎡—300cd/㎡, the gray level will not lose or people’s eyes can not perceive the gray level lose.

Low brightness and high gray level is a key parameter to distinguish the quality of small pixel LED screens. Nowadays, low brightness and high gray level rental LED display screens will be best LED screen that can meet customer’s request.
