Transparent LED Video Wall is generally divided into Positive Emitting transparent screen and Side Emitting LED transparent screen.
Positive light-emitting means that the welding surface of the lamp foot is parallel to the light-emitting surface of the lamp bead. Positive light-emitting transparent screen utilizes conventional SMD lamp beads mounted on hollow PCB boards, and centrally places the driver IC. This product is made of conventional components and conventional technology, characterized by simple production process, the use of traditional components, no light and dark lines between the light bars. The disadvantage is that the rate of hollowing is low, the position of IC concentration is easy to off-color, cutting is not flexible, not easy to customize. Positive light-emitting LED is the standard lamp bead of conventional LED display, which can ensure the all-round 160-degree viewing angle. During 2012, only positive paste positive light-emitting. After all, this process comes from the traditional conventional screen (similar to skeleton screen), so it was first adopted. At this time the LED transparent screen module before and after the acrylic board, mainly by "paste" method fixed to the glass.
Side light-emitting means that the welding surface of the lamp foot is perpendicular to the light-emitting surface of the lamp beads, Side Emitting LED transparent screen is the side of the light-emitting lamp beads with SMT process mounted on the PCB light bar. the SMT process is more difficult than the positive light-emitting products, the product is suitable for the size of the glass curtain wall, shaped customization. Advantages are high hollowing rate in flat view, high brightness, easy to customize. The disadvantage is that the upper and lower viewing angle of different hollowing different, between the light bar is easy to appear bright dark lines, flower screen, left and right viewing angle color deviation, after the screen of light leakage.
What are the advantages of Side Emitting LED transparent screen?
Higher permeability: Side Emitting LED transparent screen has higher permeability than positive light-emitting LED.
The effect is better: positive light-emitting LED transparent screen due to the lamp beads on both sides of the stent blocking, the brightness from the center of the best position along the sides of the decreasing, too low brightness leads to the audience on both sides of the stage can not see the image on the screen. Side Emitting LED transparent screen has no bracket blocking, the brightness from the front of the screen body along the two sides of the increasing, the front and left and right above the best viewing surface, so that the stage overall presentation effect is better.
Wider viewing angle: Positive light emitting LED is the standard lamp bead of conventional LED display, which can guarantee 140° viewing angle; Side Emitting Rental LED transparent screen is installed on the upper or lower side of the light bar, and the viewing angle can be up to 160°, which has a wider viewing angle, so that the audience on both sides of the stage can also enjoy the ultimate visual feast on stage. The LED transparent screen can be installed on the upper or lower side of the light bar, and the viewing angle can be up to 160°.
More convenient maintenance and disassembly: Because of the light bar design structure, a single light bar can be quickly disassembled, localized dead lights, bad lights only need to replace the corresponding light bar can be. As for the conventional Rental LED transparent screen, due to the whole PVC cover and design structure, if there is a partial replacement, the whole cabinet needs to be disassembled for maintenance, which is more troublesome.
