Background
The transparent LED display screen is composed of a plurality of LED lamp bars, and hollow parts are arranged between the lamp bars, so that transparent display can be realized. In order to obtain the best transparent display effect, manufacturers can enlarge the distance between the LED light bars; when can bear operating current voltage safely, also constantly concentrate as far as possible the wire of connecting LED lamp pearl in the LED lamp strip, contain VCC line, GND line and signal transmission line in the LED lamp strip, three wires are all very close to. The transparent LED display screen which is pursuing to be transparent lacks the black background of the common LED display screen, and the contrast is very deficient, so that the display effect is relatively weak. For the same transparent LED display screen, the display effect is good at night due to the background of the night; however, when the display is performed in daytime, the background of the night is not available, the display effect is white, and the display effect is poor.
The transparent LED display screen which is sought to be transparent has the defect that the heat dissipation effect of the concentrated wires is inevitably poor due to the fact that the wires need to be concentrated as much as possible, and the service life of the transparent LED display screen is greatly influenced.
In order to reduce the interference of external signals, metal boxes are mostly installed on the LED display module of the common LED display screen. The transparent LED display screen needs a transparent effect, and the transparent LED display screen is not realistic to be solved by adopting the installation metal box.
The transparent LED display screen which is pursued to be transparent is easy to damage due to the fact that the wires need to be concentrated as much as possible and are thin, and the structural strength of the transparent LED lamp strip is not enough.
Accordingly, the prior art is deficient and needs improvement.
