Mastering 5 skills at a glance

With the prevalence of a variety of performance activities, the market for LED large screen rental is expanding, and the demand for LED large screen rental is also increasing. The quality of LED display screens is also very different, and for the renters encountered by performance companies, the quality of the display screen directly affects the performance of the entire show, so it is necessary to lease to some high-quality LED display screens. There will be no errors in performances. So, how can we distinguish between the quality of LED display? The main difference from the following five aspects:
1 viewing angle
The size of the viewing angle directly determines the number of display audiences, so the bigger the better. The size of the viewing angle is mainly determined by the packaging method of the die.
2 production process
The performance company tells you that the main thing is to carefully observe the flatness of the display, and the quality of the production process is directly related to the flatness of the display. The surface flatness error of the display is generally within one millimeter, because It can guarantee that the image will not be distorted, and at the same time, there will be no problems such as the blind angle of the viewing angle of the display screen.
3 White balance effect
The quality of white balance is mainly determined by the display's control system. Of course, the quality of the die is also affected by the die, and this is also the most important indicator of the quality of the display. The show company tells you This generally requires attention, whether white is blueish or yellowish green.
4 There is no color block
The color patch refers to the existence of more obvious color difference between adjacent modules, and the color transition is generally based on the module. In general, the color patch phenomenon is mainly caused by poor control system and low gray level. , And scans are less frequent.
5 Mosaic and dead spots
Mosaic refers to the appearance of some often- or often-black small squares on the display screen. It is a phenomenon of necrosis in the module. The performance company learned that the main reason is that the quality of the connectors used in the display is not as high as the dead point. That is, a single point that appears on the display screen, which is always bright or dark, is mainly determined by the quality of the die.
