How to choose large indoor HD LED electronic screen - Shenzhen caishida, touch screen and OLED Forum
Four Misunderstandings of customers choosing enough LED displays: 1. Please don't just look at the price when choosing enough large screens. Price may be an important factor affecting the sales of large LED screens, although we all know the principle of "one cent for one cent", However, when choosing the manufacturers of LED electronic screens, they will unconsciously move closer to the low price.
the huge price difference causes customers to ignore the quality.
but in the actual use process.

it may be remembered that the price difference is actually the quality gap.
2. The "same model" of the display screen is not necessarily the "same product" in the sales process of large LED screens.
I often meet customers and say that the price difference is actually the quality gap, The price of the same type of display screen is so much higher than that of others.
I'm surprised, in fact.
because I quote customers according to the company's channel price.
in a chance, I found that the so-called same type of products are actually different.
we take p4led display screen as an example.
generally speaking, we mean that the pixel spacing of p4led large screen is 4.0 mm, However, there are 4.81mm display screens in the market, that is, p4.81 display screens. For those customers who don't know about it, some salesmen use the blind eye method to claim that it is P4 full-color LED display screens.
in this way, the quotation gap will be more obvious, and many customers who don't know about it still think they have bought good products at a low price.
3 The higher the technical specification parameter value is, the better. Generally, customers will choose several manufacturers to evaluate when purchasing LED display screens.
and then decide the supplier of LED large screen.
two important items in the evaluation are price and technical parameters.
in the case of similar price.
technical parameters become the winner.
many customers think that the higher the parameter value is, the better the quality of the display screen will be.
Is that actually the case? Let's take a simple example.
it's also the indoor P4 full-color display screen. In terms of the brightness value of the display screen.
some manufacturers will write 2000cd / m2.
some manufacturers will write 1200cd / m2.
is 2000 better than 1200? The answer is not necessarily.
, because indoor LED screen brightness requirements are not high, generally between 800 and 1500.
can be too high, but will glare affect the.
viewing from the life expectancy, too high brightness is also easy to overdraw the display life.
. So reasonable use of brightness is positive solution.
is not the higher the brightness, the better.
4. The production and testing of display screen is not as short as possible. Many customers who buy led full-color screen just place an order and want to get the goods right away.
we understand this mood.
but LED large screen is a customized product, After the completion of the production, it needs at least 48 hours of testing.
caishida LED screen adds 24 hours to the national standard to achieve 72 hours of uninterrupted testing.
if the delivery time is too short, there are generally two problems: one is that it has not undergone sufficient testing.
the failure rate in later use will be relatively high; However, some manufacturers do not have enough stock of the same batch, so they may use products of different batches in order to place orders.
in this way, the display screen will have obvious color difference.
greatly affect the display effect of LED large screen.
