What are the performance measurement factors of LED full color screen

　　LED displays are as important as the engine of a car or the compressor of an air conditioner. Select a good performance LED is the basic condition to complete a high performance LED display. So what are the performance measurement factors of LED full color screen?

　　1, control card basically 99% of the led full color screen manufacturers are outsourcing, the work is better that is Nova, Ling star rain, Qing, Depu, Carlette, Kaida and so on, these are used in full color LED full color screen is more, relatively speaking, the stability is better.

　　2, led full color screen driver IC: at present, led full color screen to expand the driver IC has bright micro, accumulation, innovation, sun and moon, rich and some relatively low-end driver IC; IC image quality is very clear, no scan lines, low failure rate.

　　3. Circuit board: More domestic PCB manufacturer, and shenzhen is the centre of electronic products, purchasing raw materials so that a very fast, circuit board can be divided into two layer board and four layer board, the thickness of two layer board is 1.6, four layer board is 2.0, can the elements affecting the quality of circuit board has a circuit board inside the conductive body, the thickness of the conductive to reach the thickness of the specification to above 1 ns, Due to the temperature rise and fall of led full color screen in the process of operation, if the conductive copper skin is thin, the LED module will be fused in the process of use, so there will be a large area of quality problems.

　　4. The problem of mask and kit: the ink color of mask and consistency directly affect the flash effect of led full color screen. Assuming that the ink color is good and the quality of led lamp is good, the flash is basically no big problem.

　　5, the waterproof performance of outdoor LED full color screen depends on whether it is machine glue or artificial glue, glue is good or bad, AB glue ratio share is related.

　　6, the process of the box body: whether the box body is flat is related to the machine equipment of the box body and artificial welding technology of the manufacturer. The LED full color screen box body is done well, the flatness of the whole screen will be much better, and the joint is also very small.
