Of course, the discrete nature of the LED itself birth defects also exist: (1) the lamp manufacturer's own existence LED lamp brightness, chroma difference (2) Space Henan LED display luminous intensity distribution there are differences This will lead to a different location on any viewing angle LED luminous intensity with respect to inconsistencies attenuation of the optical axis direction; many other factors LED display manufacturing process introduced: (1) flatness module assembly (2 ) flatness of the housing assembly (3) flatness of the mask, and the ink of discrete (4) module internal heat uneven distribution (5) LED welding time axis deviates from the normal direction of the display, especially line For these reasons control LED optical axis direction will cause the LED display has a problem may exist undesirable uniformity, therefore installed at the factory, the workers will be on the LED display by-point correction to ensure color LED display uniformity, thus ensuring the quality of LED display playback screen.
