10 guidelines for purchasing indoor LED display this year
1. Dimensions
We should select the indoor LED display screen with appropriate size according to the project site and the display screen use. If the viewing distance is relatively long, even if the screen definition is high and the screen area is too small, it will not have a good user experience. On the contrary, we can increase the size of the display screen and appropriately reduce the product point spacing, so that the effect will be better.
2. Brightness
As a buyer, you must understand the conditions and location of using the screen, which will help you determine the required screen brightness. For indoor LED display, 600 nit LED screen may be the best choice, and the brightness of outdoor LED display is usually more than 2000 nit. The high-quality indoor LED display has the option of manually and automatically adjusting the screen brightness level, which will allow you to ensure a perfect visual experience in different environments or conditions.
3. Installation
LED screens or monitors use the same technology to display content, but their installation methods vary depending on the brand you choose. If you want to save money and time on professional installation, you can buy fully assembled indoor LED screens. When renting or purchasing LED screens, it is necessary to talk about their installation procedures. A few LED screens need professional installation, Other LED screens can be easily installed without professional help. Here is the installation case of led display for reference.
4. Maintenance
For LED display maintenance, you can maintain it from the back or front. Now many manufacturers have introduced the LED display of the front maintenance series, which brings greater convenience to maintenance and can greatly save installation space. At the same time, it is also necessary to ensure that it is easy to buy the materials for the later maintenance of the indoor LED display. Here is a professional guide for repairing led display.
5. Perspective
The viewing angle of indoor LED display screen is quite important. If you want to have a good viewing experience and can clearly see the content on the display screen from different angles, the viewing angle needs to be wider. The viewing angle of LED display screen depends on the LED packaging. Therefore, if you have no budget constraints, you should choose the indoor LED display with better packaging.
6. Dead light rate
There are as many as millions of small lamp beads on the indoor LED display screen. It is inevitable that the dead light will occur after a long time of use. However, a good brand of lamp beads can greatly reduce the dead light rate and at the same time provide a comfortable picture quality display.
7. Grayscale
Gray level is an important indicator of LED display screen. At present, the market is full of many 14-level and 80-level display screens that pretend to be 256-level display screens, and the control cost of the former may only be a small part of 256-level display screens.
8. Density
Due to the large heating capacity of indoor full-color LED chips and the high density of control circuits, the point density of commercial full-color screens can not be very high.
9. White balance effect
The white balance effect is one of the most important indicators of the display screen. When the ratio of red, green and blue primary colors is 1:4.6:0.16, pure white will be displayed. If there is a slight deviation in the actual proportion, there will be a deviation in the white balance. Generally, we should pay attention to whether the white color is bluish or yellow-green. The white balance is mainly determined by the control system of the display screen, and the tube core also affects the color restoration.
10. Refresh frequency
Refresh frequency refers to the number of times the display screen is repeatedly displayed by the display screen. In theory, the higher the refresh rate, the better the display effect. Generally speaking, the refresh frequency of indoor display screen is above 180HZ, and that of external display screen is above 300HZ.
When we choose indoor LED display screens, the correct way is to choose the right products according to our own needs, not blindly buy because of the price of LED display screens. Only by selecting the right products can we better use LED display screens to create more benefits.
