A good supplier, with good product quality, good service, and reasonable price, can reduce the problems in the use of indoor LED displays. How to check and review whether the supplier is reliable? The following points are for reference:

LED display industry years: Generally speaking, it is very good that the company has been established in the LED display industry for more than 10 years. If the quality and service are not good, it can exist for a long time.

Professional staff: Whether the sales or managers you contacted are professional, whether they can respond quickly to your questions, whether they can provide quotations quickly, and whether they can provide you with professional advice and services, can largely reflect the follow-up service attitude and reliability.

Customer Reviews: Customer feedback is a very real evaluation, it is more objective and more effective than the supplier’s own introduction because the customer is in the middle and there is no partiality.

Quality service: The service can reflect whether it is professional, reliable, or trustworthy. Be sure to choose a supplier with high-quality services.

No, the LED display can play any aspect ratio video source, in fact, the aspect ratio of 16:9, 4:3, etc. is not important. Like many of our products are super-long screen, also disseminate information, commercial advertisements are pretty good, such as perimeter led display.

The lighting principle is different: the LED screen is the abbreviation of the light-emitting diode. It is packaged into small lamp beads by chips, arranged on the PCB board, and formed by splicing to form a large screen to display images;
LCD is a liquid crystal display technology, which is a liquid crystal panel composed of LED backlight to present images display images;

Brightness: The brightness of the LED screen is 600-6500 cd/m2, and the brightness of the LCD is 250-1500 cd/m2. so LCD only can be used indoors;

Color: The color gamut of the LCD screen can generally only reach 70%. The LED display color gamut can reach 110%;

LED Screen splicing: LED large screen experience is good, seamless splicing can be achieved, and the display effect is consistent. The LCD mirror reflection is serious, after splicing for a period of time. Due to the different degrees of attenuation of the LCD screen, the consistency is different, which will affect the look and feel.

Maintenance cost: The maintenance cost of the LED display is low, and once the LCD liquid crystal display leaks, the entire screen must be replaced. The LED display only needs to replace the module accessories;

Viewing angle: The angle of the LCD display screen is very limited, which is a very lively and troublesome problem. As long as the deviation angle is slightly larger, the original color cannot be seen, or even nothing. The LED can provide a viewing angle of up to 160°, which has great advantages;

Contrast ratio: The currently known relatively high-contrast LCD display is 350:1, but in many cases, it cannot meet various needs, but the LED display can reach higher and be used more widely;

Under normal use, the life of an indoor LED screen is 100,000 hours, it depends on the method of use, the environment of use, etc., they will prolong and shorten the service life.
