High quality P4 indoor full color display Cost

China good old saying: no good cheap goods. Huangshan LED electronic display manufacturers offer full-color display PH4 PH4LED display Epistar brand manufacturers, custom Huangshan Huangshan LED indoor display LED large-screen multimedia electronic display equipment suppliers, PH4 full-color electronic display manufacturers latest wholesale unit price. Especially in the electronics market, it pays for, the good stuff is not cheap. In the current market, LED display, LED screen due to competition between manufacturers increasingly fierce, LED electronic display business survival increasingly difficult. Many display manufacturers began to play 'low-end card', intended to amount of waste products to make up for loss of profits to P10 outdoor full-color LED display, for example, the manufacturer A offer 4,500 yuan / square, factory B offer 4,300 yuan / square manufacturers C offer 3300 yuan / square, as well as more manufacturers to lower the price of D or E, exercise price had friends all know, no matter what kind of manufacturers reported price, LED chips are all brand Taiwan wafer. A difference of 2,000 yuan per square P10 full-color LED display lamp beads used turned out to be the same brand, I think a little mind of the customer will find the problem, we all know that the major cost of LED display LED chip, if the chip is exactly the same whether you are a listed company or small workshop, the entire screen price break will not differ so much! So it is only one possibility: some manufacturers lying. Careful scrutiny we find that, with the die manufacturer C certainly not genuine.
