The function of LED full-color display screen

1, which can promote commodities and attract customers.

2. Play the role of store decoration, and improve the enterprise grade.

3, play the role of lighting, unconventional.

4. Play the role of popularizing knowledge. (Can be used to play small information about enterprise products and knowledge of related industries)

5. Play the role of bulletin board. (Promotion, recruitment information release)

6. Play a role in setting off the atmosphere. Through the display screen, you can play the welcome speeches of superior leaders and various VIPs, and the celebration speeches of various major festivals.

Basic principles for evaluating the performance of LED display screen

Because LED display screen is a professional product, non-professional customers generally do not have the basic knowledge to judge the product, so we must first establish a recognized evaluation standard. As a large-scale information display terminal, LED display screen's basic function is to comprehensively and faithfully display the information of information sources to the target audience, including static images, characters, dynamic videos and even audio. Therefore, this standard is simply "good-looking", and what is shown to people is definitely good for people to see. This omits a lot of technical terms, and also helps to close the distance with customers and reach basic standard knowledge.

But why are some displays "good-looking" and some displays "not good-looking"? This is because of two key factors that affect the display effect of the display screen:

1. Brightness of display screen: In order to display information correctly in an environment, there must be enough brightness to ensure the actual contrast of images, especially for outdoor LED display screens with harsh outdoor environment conditions. Therefore, according to the different use environment, the display screen must have the corresponding brightness to ensure.

After the display screen is put into use, the brightness of the LED tube as a light source begins to decay, so the brightness decay rate is one of the important properties of the LED display screen.

2. Consistency of display screen colors: When displaying primary colors, the brightness and chromaticity of each color are consistent, and when displaying white, there is no noise. This is the basis to ensure the correct restoration of color information of information sources.

In the initial stage of LED display, it is generally necessary to ensure color consistency. With the attenuation of LED tubes in use, the attenuation curve of each LED tube is different due to the individual differences of semiconductor devices and LED production technology, which leads to the worse color consistency of the display screen with the increase of use time.

Based on the above two basic evaluation criteria, we can reach a * * * understanding with customers: one of the important factors to judge the internal quality of the display screen is the choice of LED:

Low attenuation rate and good consistency of attenuation curve.

To ensure this, firstly, the manufacturers of LED lamps should have excellent manufacturing technology, and secondly, the LED tubes should not be hit by static electricity during the whole production process of the display screen.
