3.After the computer enters the engineering control software, the screen can be turned on and powered on.
4.Avoid opening the screen in the state of full white screen, because the impact current of the system is the maximum.
5.Avoid opening the screen out of control when the impulse current of the system is the maximum.A. The computer does not enter the control software and other programs;B. The computer is not energized;C the power supply of the control part is not turned on.
6.When the environment temperature is too high or the cooling condition is not good, you should pay attention not to open the screen for a long time.
7.When a line of led display is very bright, please turn off the screen in time, and do not open the screen for a long time in this state.
8.If the power switch on the display screen often trips, please check the screen body or replace the power switch in time.

5. How to choose LED large screen
What are the factors that take into account the screen area allowed by the user site?
(1) the relationship between the effective stadia and the actual site size;
(2) pixel size and resolution;
(3) area estimation with the element as the radix;
(4) operation space for mechanical installation and maintenance of the screen body;
(5) influence of screen body inclination Angle on distance.
What are the playback effects that users need?
(1) text display: it depends on the size of the text and the demand for distinguishing;
(2) ordinary video display: 320 * 240 lattice;
(3) digital standard DVD display: more than 640 x 480 lattice;
(4) complete computer video: greater than or equal to 800 * 600 lattice;
What brightness requirements does ambient brightness have for the screen body?General brightness requirements are as follows:
(1) indoor: >800CD/M2
(2) half room: >, 2000CD/M2
(3) outdoor (sitting south to north) : >4000CD/M2
(4) outdoor (north facing south) : >8000CD/M2
What brightness requirements does red, green and blue have in terms of white composition?
