Here we only talk about conventional products. Let’s take a look at the factors that affect the quotation of LED display.
In terms of color, LED advertising display can be divided into monochrome, two-color and full-color. In terms of use environment, it can be divided into indoor, outdoor and semi outdoor. The price of each specification of LED screen is different. Indoor full-color can be divided into full-color, three in one full-color and dot matrix full-color. Outdoor full-color can be divided into 1R1G1B (generally high-density, such as PH10 and pH12) 2R1G1B (generally high density, such as PH16, PH20, etc.). Many manufacturers in order to reduce costs, will use a bright red light to color!
Materials have a great influence on the price of LED displays
In terms of materials, they can be divided into imported materials and domestic materials. In terms of light-emitting chips, the sources of imports include the United States, Japan and Taiwan. At present, there are also some domestic chips. Each light-emitting chip has its own advantages and disadvantages. The chip prices of the United States and Japan remain high under the background of similar monopoly because they have always mastered the core technology. The price of chips in Taiwan and the mainland is relatively cheap, but there is still a certain gap between the performance of chips in Taiwan and the United States and Japan. If the LED advertising display is used in more important occasions, we recommend to use imported materials; In addition to LED chips, the main factor affecting the price of LED advertising display 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 life of Les display. When making full-color LED advertising display, I must use constant voltage and constant current driver IC; Other materials, such as power supply, box, and various accessories for making display screen.
The influence of main supporting systems on the price of LED advertising display screen:
① System accessories: sending card, receiving card, transfer card;
② Play system: control computer, multimedia card or graphics card, play software;
③ Editing system: editing computer, video compression card, editing software;
④ Monitoring system: sensor + monitoring software;
⑤ Protection system: heat dissipation system, power distribution system, lightning protection system, temperature and humidity monitoring system;
⑥ Sound system: amplifier + speaker;
⑦ Video input equipment: DVD / VCD, VCR, CCTV;
⑧ Image and text input: scanner, digital camera.
The above accessories and equipment are optional except system accessories and playback system. Due to the influence of brand and purchasing channel, the price of LED advertising screen is naturally different.
