![]() ![]() Engineers compensate for the lack of brightness in the form of loss of color expression. ![]() ![]() When it is black or gray, his light-emitting diode color (white) also participates in the color to be expressed on the electronic display, which produces color distortion (cannot express black, gray, dark green, etc.) ). Due to the low brightness of the early illuminating wafers, engineers have made the plastic brackets into a white bowl shape to enhance the focusing and reflection, so as to ensure that the wafers with low brightness reach a brighter effect.īut the white lamp also has shortcomings. The led display screen is assembled from plastic brackets and illuminating wafers. But what are the technical differences between the two kinds of lamp? At present, the outdoor led display on the market generally uses a white lamp, and the indoor led display uses a black lamp, especially in the category of small-pitch led display and stage drape screen. ![]()
