Now, in that place, the LED display is becoming more and more widely used, the visible pictures, the video screen and so on. In the process of use, we will find a bright line in the Chongqing LED display screen. In order not to affect the effect, how should we solve the problem of this bright line?
One, buy a big screen, please don't just look at the price
The price may be an important factor affecting the LED big screen sales, although everyone knows the reason for a cent of the money, but in the choice of the LED display manufacturer, it will not be conscious to close to the low price. The huge price difference caused the customer to ignore the quality. But in actual use, it may be remembered that the spread is actually a quality gap. Four Misunderstandings of selecting and buying LED display screen easily
Two, the same type of display is not necessarily the same product.
In the LED big screen sales process, I have often touched the customer said, the same type of screen, why your price is more expensive than others. I am very surprised, actually, because I quote prices to customers according to the company's channel price. In a casual chance, I discovered that the same type of product is actually different. We take P4LED display as an example, generally speaking, we say P4LED big screen refers to the distance between pixels is 4.0mm, but the market has a distance between 4.81mm, that is, p4.81 display, the customers do not understand, some salesmen use the barrier, claim that P4 full color LED display. As a result, the price gap will be more obvious, many customers do not know that they bought a good product at a low price.
Three. The value of technical specifications is not higher and better
General customers purchase LED display will select several manufacturers for comparison, and then decide LED big screen supplier. The two important factors in evaluation are price and technical parameters. In the case of similar prices, technical parameters become the winner. Many customers think the higher the parameter value, the better the quality of the display. Is that actually the case? Let's give a simple example, which is also an indoor P4 full color display screen on the screen brightness value. Some manufacturers will write 2000cd/ square meters, and some manufacturers will write 1200cd/ square meters. Is that 2000 better than 1200? The answer is not necessarily, because indoor LED screen brightness requirements are not high, generally between 800 and 1500. The brightness is too high, but it will glare affect the viewing. From the service life, too high brightness is also easy to overdraw the screen life in advance. Therefore, the reasonable use of brightness is the positive solution, not the higher the brightness is better. The same model also requires some parameters, such as LED lamp brand / package, scanning mode, power refresh rate, power consumption, grayscale and so on, and the price will not be the same with different parameters.
Four. The production and detection of the display is not as short as possible.
Many customers who buy LED full color screen just want to place orders, so they can't wait to get them. We understand this kind of mood, but the LED big screen is a customized product, and it needs at least 48 hours of testing after production. LED display on the national standard increased 24 hours to reach 72 hours without interruption test. There will be two problems in the short period of time: one is that there is no sufficient test, and the failure rate will certainly be relatively high; but some manufacturers do not have enough spot in the same batch, and it is possible to use the same batch of products for the next order. In this way, the display screen will have obvious color difference, which will greatly affect the LED large screen display effect.
