The six elements about debugging new LED display

   After the LED display installed, you must first commissioning if it can work, then what display LED display can work normal? MRLED organize six commonly used elements for you.

1, Brightness and viewing angle

Indoor full color brightness 800cd/m2 over to the outdoor full color brightness to the 1500 cd/m2 or more, to ensure the normal operation of the display, otherwise it will be too low and can not see because of the brightness of the displayed image. Led by the size of the brightness of the die determines the quality. How much the size of the audience viewing angle of the display is directly determined, therefore the bigger the better. Mainly by the size of the viewing angle of the die package to decide.

2, White balance

Balance effect is one of the most important indicators led display. Primary colors red, green and blue color science fooled ratio of 1:4.6:0.16 only when showing pure white, a little deviation if the actual proportion of white balance deviation occurs, usually pay attention to whether there is bluish white, yellow green phenomenon. The white balance is good or bad is determined by the display control system of the die to the reduction of color is also affected.

3, The reduction of color

Reduction of color is the color display of color reduction, both led display to be highly consistent with the source color, so as to ensure that the image of realism.

4, Mosaic, dead phenomenon

Mosaic is the steady appear on the led display or normally four small black boxes, both modules necrosis, which was mainly due to the quality of connectors used, but off screen. Always dead point is shown on the display or normally black single point, how good or bad mainly by die to determine the dead point.

5, Color piece

Color refers to the existence of obvious color difference between adjacent modules, the transition of colors in the module as a unit, the color phenomenon is mainly caused by the control system is poor, the gray level is not high, due to the lower scanning frequency.

6, Flatness

To display surface flatness within ± 1mm, in order to ensure the display image is not distorted, partial raised or recessed causes the display viewing angle appears dead. Flatness is mainly determined by the quality of the production process.
