A. What is the difference between LCD display and indoor LED display?
There are many differences behind them, the most obvious one is the backlight. the LED display itself can emit light and has a high brightness level. If you want a bright and clear screen, then an LED screen would be your best choice, if you just want to achieve something in the middle, then consider an LCD display.
In addition, the size modular, indoor led display can be combined into a larger display, while LCD displays usually can not.
B. What is a reasonable pixel pitch for an indoor LED display?
It depends on your desired viewing distance, the smaller the pixel pitch, the closer the distance between the displays, and the closer your acceptable viewing distance. The pixel pitch for indoor displays is typically between 4mm and 20mm, and the optimal viewing distance is usually 2-3 times the number of pixel pitches in meters. For example, a pixel pitch of 2 will allow viewing from a distance of 4 meters, while a pixel pitch of 10 will require a distance of at least 20 meters to experience the best detail.
C. What is the size of the indoor LED display?
You can choose from a variety of sizes. Typically, indoor displays are smaller than outdoor LED displays.LED modular design allows small LED displays and giant LED displays to be as large as you want.
D. What are the important parameters for buying indoor LED displays?
They are usually brightness/viewing distance/power consumption/refresh rate, it will determine your screen display effect and some operation cost.
A. Rich professional experience
Try to focus on companies that have a lot of experience with the type of display you want to buy.
For example, some of them may have professional experience in producing traditional LED displays, but are not so skilled in some creative LED displays. Therefore, check their hands-on experience to know what type of LED screen you really want.
B. Qualified product quality
You can check it by asking about the company's certification and qualification. If conditions allow, you can visit the factory for a site visit.
If the situation does not allow - first, you can check the industry certifications. Second, ask for photos or videos of the factory. Third, search for the company's reputation to see if its products and services enjoy a good reputation. Of course, it is necessary to have photos and videos of the actual visual effects of the final product.
C. Reasonable price of LED display
You can consider the price from several aspects of the product - LED lights, case, size, brightness, protection level, other components and other specifications. Therefore, the price range may vary, but there is still a rule of thumb - there is a positive correlation between price and product quality. Therefore, do not choose too many LED display products with lower prices than the market, which will increase the risk of inferior products or outdated services.
D. Delivery capability
Timely delivery capability can reduce the possibility of project delays, but also reflects the comprehensive strength of an LED display supplier. In addition, the speed of transportation is also necessary. And the products should be packed correctly and carefully to ensure that the LED beads and components are not bumped and damaged.
E. Considerate service
Whether after-sales service, in-sales service or after-sales service, are the key to get a satisfactory customer experience and stable use of the product. LED display can last for 10,000 hours when used in the right way, so it is essential to choose a professional and timely service from LED display suppliers.

Let’s talk about the seven common scenes of using LED screen.
1、 Check circuit and switch and keep switch dry in case electric leakage.
2、 Air condition and desiccant will be very effective to keep screen dry.
3、In raining season, please keep using the screen twice a week.
4、Appropriate ventilation will prompt the drain on the screen to evaporate soon but it is not a good idea to ventilate in wet weather.
5、Check cabinet and parts like waterproof rubber gasket or screw in a regular interval.
6、In raining day, please turn off power immediately when using indoor rental screen for outdoor purpose. If you don't want to disassemble the screen then you can use waterproof cover to cover the screen. If rain fall continuous, please open the back door of the screen and use dryer to blow it.
7、It is very necessary to turn on the screen in a regular interval even you plan not to use it for a long while.
If you take a good look on these seven common scenes, you can maximize the performance of LED screen and the screen will create a great value for your company.
What is the reason that cause frequent tripping on LED screen? How do we handle it? You will find out the answer after reading this article.
1、 Tripping caused by inappropriate protection for electric leakage. The installation for full color LED screen is unusual. Wrong cable connection, damaged electric leakage protector and accidental alarm from electric leakage protector are the main reasons cause the situation. In addition, inappropriate distribution of the electric leakage protector on circuit will also cause tripping.
2、 There is no effective second or third level electric leakage protection. The last level of electric leakage protection in the switch box is main protection. A bad choice of the last level protection may trigger upper level protection trip-out. So multiple protection level is very important.
3、 The leakage protector has few limitations. Under high electric current or high voltage, the protector might trip-out easily.
4、 There is a range between rated leakage executed current and non-executed current. So trip-out happens when the leakage current is fluctuate in this rang.
LED display has wide application in daily life no matter for company or government. So it is necessary to have solutions to solve problems for the screen.
