With the increasingly wide application of LED display screen, various LED display screen manufacturers have sprung up , and the prices of LED display screens are also different .
Sometimes the prices of some LED display screen manufacturers vary greatly . In fact , people familiar with the LED display industry know that many factors affect the price of LED displays . Now we will explain the main factors affecting the price of LED displays from the following three aspects .
1 . Raw material IC chip
first of all , take the light-emitting chip , which can be divided into imported materials and domestic materials . Each kind of light-emitting chip is different and has its own advantages and disadvantages . The price of chips in the United States and Japan remains high because they have always mastered the core technology .
The price of chips in Taiwan and the mainland is relatively cheap , but their performance still lags behind that of chips in the United States and Japan . If the LED display screenis used in important occasions , we recommend using imported materials ; In addition to LED chips , the main factor affecting the price of LED display screen is led driver IC .
However , if I am a customer , I would rather choose a better driver IC , because although the price is higher , the driver IC is a very important factor affecting the quality and service life of LED display screen .
When making LED full-color display screen , we must use the driver IC with constant voltage and constant current ; Other materials , such as power supply , box , and various accessories for making display screen .
2 . Product specifications
our products here refer to conventional products . In terms of color , the LED display screen can be divided into monochrome , two-color and full-color . It can be divided into synchronous and asynchronous according to the control or use mode . In terms of to use environment , it can be divided into indoor , outdoor and semi outdoor . The price of each specification of LED screen is different . The indoor full-color can be divided into table paste full-color , table paste three in one full-color and dot matrix full-color , Outdoor full-color is divided into 1R1G1B (generally high-density , such as PH10 , pH12 ) and 2R1G1B (generally high-density , such as PH16 , PH20 , etc . ) . Different specifications require different configurations , so the price will be different .
3 Main supporting systems
Editing system : editing computer , editing software , video compression card .
System accessories : receiving card , sending card and transfer card .
Playback system : control computer , multimedia card or graphics card and playback software .
Protection system : power distribution system , heat dissipation system and lightning protection system .
Monitoring system : sensor + monitoring software .
Sound system : loudspeaker + speaker .
Video input equipment : video recorder , DVD / VCD , closed-circuit television .
Graphic input : digital camera and scanner .
Except for system accessories and playback system , other settings of the above accessories and equipment can be freely selected according to their own conditions . The price of its LED display screen will also be affected by factors such as brand and procurement channel .
