Indoor LED display market is more and more optimized by the enterprise, large and smallLED display manufacturers such as spring version emerged, but each manufacturer's technology is not the same, a variety of quality is not satisfactory products in the LED display market. However, only the production of high-quality indoor LED display is the enterprise in the market based on the fundamental.

First, the LED display needs to be corrected point by point

The discrete nature of the LED itself is inherently defective. Lamp manufacturers to provide the LED itself there is brightness, chromaticity variability. Due to the flatness of the module assembly, the flatness of the box assembly; the flatness of the mask, as well as the dispersion of the ink color; LED welding time axis direction away from the normal direction of the display, especially in the direction of the optical axis of the straight LED, etc. In the actual production process, the uniformity of the LED display will be affected by a number of factors, so there is no correction of the uniformity of the LED display can not reach the ideal level, the quality of the picture with the other flat panel display technology compared to a significant gap. Compared with other flat panel display technology, there is an obvious gap.

When the LED display after a period of time, due to the LED individual differences in light failure, as well as other external reasons, the uniformity will further deteriorate, which is manifested in the display of a large number of pockmarks on the screen, bright dark spots and even mosaics, commonly known as the “flower screen” phenomenon.

Point-by-point correction technology allows users to reduce the cost of significantly improving the uniformity of the display, significantly improving image quality. Applied to the factory, point by point correction is a quality improvement means, means the competitiveness of the competitiveness of the promotion and profit space expansion; Applied to the use of a period of time, point by point correction can extend the LED display “pleasant eye life”, for users to create more business value, reduce the waste of resources.

Second, select high-quality LED lamp beads

The high reliability of LED lamp beads refers to its ability to maintain the stability of the quality of the customer's whole process of use, the use of LED lamp beads, probably divided into so many links. First of all is the factory inspection link, in the production factory through the final visual inspection and electrical performance test after passing, packaging factory; Next is the transportation and storage link, after transportation, storage and other links to reach the display factory; Then is the production and processing link, the screen factory to open the packaging, through the production process of the board and welding, to complete the finished product of the production and processing of the display; Ultimately is the normal use of the link. In this whole process, LED lamp beads must work reliably, can not appear dead phenomenon. During this period LED lamp beads to be able to withstand moisture expansion and temperature shock and other tests, especially the highest temperature up to 260 degrees welding temperature shock. The LED lamp bead is composed of a variety of different materials, such as metal copper, resin, PPA, conductive adhesive, light-emitting chips, etc., their moisture expansion coefficient and temperature expansion coefficient is different, so the material between them is quite critical, such as improper coordination will appear dead. So it is necessary to simulate the use of LED lights to determine its reliability.

Indoor full-color LED display in the comprehensive consideration of cost-effective, point spacing is an element that can not be ignored. Generally speaking, the display screen point spacing is not only closely related to the screen display accuracy, viewing distance, application places, but also one of the determining factors of the price of the display, the smaller the point spacing, the higher the price is naturally, corresponding to the LED screen effect is also better. That under the conditions of the budget allows, the smaller the pitch is not the better?

LCF LED display manufacturers tip: In fact, as long as the LED display industry a little understanding, it is not difficult to find that even if you do not take into account the premise of the budget, indoorfull-color LED display the appropriate point spacing is not the smaller the better, but to take into account the place of area, viewing distance, and whether you need to support a special display effect. People in the consultation and purchase, rich decades of experience in shenzhen LCF and other large LED display enterprises will understand in advance the application place, installation height, in order to provide the best economic and reasonable solution. If there are enterprises insist on recommending a smaller pitch, we need to carefully screen, for their own selection of a suitable enterprise and a suitable product.
