At present, Shenzhen and Guangzhou LED industries are the most mature industrial bases in China. There are complete production systems, upstream and downstream suppliers, and mature industry models. There are tens of millions of companies engaged in LED products in the Pearl River Delta. There are more than 500 factories producing LED outdoor displays in Shenzhen, and 40% of them mainly provide processing services, as well as small workshop-style production. There are also a group of manufacturing companies focusing on quality and R&D.
affect the price of LED electronic display screens There are four main reasons that :
Nowadays, there are more and more classifications of LED display screens, so there is a frequent war on the price of LED electronic display screens. The competition in the LED display industry has reached fierce competition, and various manufacturers even offer completely different prices for the same products. In fact, if you are familiar with the LED display industry, there are many reasons that limit the price of LED displays, such as LED display specifications, material system supporting factors and construction reasons, which will all affect the price of LED electronic displays. Then why does it affect the price of LED displays for this reason?
first. The impact of main supporting systems on the price of led electronic displays
1), LED outdoor display playback system: control computer, multimedia card or graphics card, playback software;
2), LED outdoor display editing system: editing computer, video compression card, editing software;
3), LED outdoor display system accessories: sending card, receiving card, adapter card;
4), LED outdoor display sound system: amplifier + speaker;
5), LED outdoor display video input equipment: DVD/VCD player, video recorder, closed-circuit television;
6), LED outdoor display monitoring system: sensor + monitoring software;
7), LED outdoor display protection system: heat dissipation system, power distribution system, lightning protection system;
8), Graphic input of LED outdoor display: scanner, digital camera. The above accessories and equipment are optional except for system accessories and playback system. Due to factors such as brands and purchasing channels, the prices of outdoor LED displays are naturally different.
Second, the impact of construction factors on the price of LED displays
LED outdoor display screens are affected by factors such as installation location, installation method, screen size, frame structure selection and other factors. The project price of LED outdoor display screens will definitely have a relatively large difference, especially when making LED outdoor display screens, which are affected by the construction environment. The project price varies greatly.
Third, the impact of specifications on the price of led electronic displays
Here we only talk about conventional products. In terms of color, LED outdoor displays can be divided into single color, two-color, and full-color. From the use environment, they can be divided into indoor, outdoor and semi-outdoor. The price of LED outdoor displays of each specification is different. It is different.
Indoor full color is divided into surface mount full color, surface mount triple full color, dot matrix full color, outdoor full color is divided into 1R1G1B (generally high density, such as: PH10, PH12), 2R1G1B (Generally high density, such as PH16, PH20, etc.).
Fourth, the impact of materials on the price of led electronic displays
The materials are divided into major categories, which can be divided into imported materials and domestic materials.
In terms of light-emitting chips, the sources of imports are: the United States, Japan, Taiwan, and some domestic chips are also currently available. Each light-emitting chip has its own advantages and disadvantages. American and Japanese chips, because they have always mastered the core technology, under the background of similar monopolies, the prices of American and Japanese chips remain high. Chip prices in Taiwan and the mainland are relatively cheap, but there is still a certain gap in performance compared to chips from the United States and Japan.
If the LED outdoor display is used in more important occasions, it is better to recommend the use of imported materials; in addition to the LED chip, the main factor affecting the price of the LED electronic display is the LED driver IC, but if I am a customer, I would rather choose A better driver IC, because although it is a bit more expensive, the driver IC is a very important factor affecting the quality and life of the LES display. When making a full-color LED outdoor display, you must use a constant voltage and constant current driver IC; Other materials such as power supply, cabinet, and various accessories for making display screens.
