by:GKGD     2020-05-07
The stand or fall of a shenzhen LED full color to sign can mainly from the following several aspects: 1. Flatness of shenzhen LED full color of surface roughness to within + / - 1 mm, to ensure that the display image is not distorted, local convex or concave leads to shenzhen LED full color the visual Angle of corner. The stand or fall of flatness is mainly decided by the production process. 2. Brightness and the viewing Angle the brightness of the indoor full color LED in shenzhen in 800 CD/m? The brightness of the above, shenzhen outdoor full color LED to in 1500 CD/m? Above, in order to guarantee the normal work of the shenzhen LED full color, otherwise it will because the brightness is too low and can't see shown in the image. Mainly by the size of the brightness of LED tube core is good or bad decision. Directly depends on the size of the viewing Angle of shenzhen LED full color how many of the audience, and the bigger the better. The size of the viewing Angle is mainly composed of tube core encapsulated way to decide. 3. The white balance effect white balance effect is one of the most important indicator of shenzhen LED full color. Chromatology on red, green and blue color for the proportion of 1:4. Lost. 16 will only show the pure white, if the actual rate is a little deviation will appear white balance deviation, generally pay attention to whether there is a slant blue, white slant yellow phenomenon. The white balance of LED full color of the control system is mainly composed of shenzhen to decide, also has effect on the tube core of color reducibility. 4. The reducibility of color reducibility is refers to the shenzhen LED full color of color reducibility, both shenzhen LED full color display color to maintain highly consistent with the colour of the source, so as to ensure the image sense of reality. 5. Have * * g, dead point refers to the phenomenon of Mosaic shenzhen LED full color on the normally on or often black small four squares, both module necrosis phenomenon, the main reason for the shenzhen LED full color of connector quality closes nevertheless. Dead center is refers to the shenzhen LED full color on the normally on or black often a single point, how many of the dead point is mainly composed of the stand or fall of the tube core to decide. 6. Exist between those with and without the shades of color piece is refers to the adjacent modules are clear off color, color transition in module, color piece phenomenon caused mainly by the control system is poorer, grey level is not high, caused by lower scanning frequency. 【 Shenzhen LED full color.
