Abstract

A LED display device with high transmittance is revealed. The LED display device with high transmittance consists of a plurality of horizontal display strips arranged at certain intervals and parallel to one another, a plurality of support members for connecting and supporting the plurality of display strips, a power cable together with a signal wire for sending electrical signals and driving the LEDs to emit light. The horizontal display strip includes a long horizontal frame, a strip circuit board, and a plurality of light emitting diodes (LED). The LED is side LED arranged on the circuit board at equal intervals and the circuit board is horizontally mounted in a long chamber of the long horizontal frame so as to reduce forward height as well as forward area of the long horizontal frame for increasing light transmittance of the LED display device.

Claims

1. A light-emitting diode (LED) display device with high transmittance comprising a plurality of horizontal display strips disposed at certain intervals and parallel to one another, a plurality of support members, a power cable and a signal wire;

wherein the horizontal display strip includes a long horizontal frame, a strip circuit board, and a plurality of light emitting diodes (LED);

a long chamber is arranged inside the long horizontal frame for mounting the strip circuit board, and the plurality of LEDs while the LEDs are side LEDs and are disposed on the strip circuit board along the horizontal direction at equal intervals;

the support members are connected vertically and are supporting the plurality of horizontal display strips arranged at certain intervals and parallel to one another;

the power cable is connected to the display strips for providing power;

the signal wire is connected to the display strips for transmitting electrical signals;

by the power cable and the signal wire, the LEDs are driven to emit light for display effects;

wherein the plurality of side LEDs are disposed on the strip circuit board along the horizontal direction at equal intervals and the strip circuit board is mounted into the long chamber of the long horizontal frame horizontally so as to reduce forward height of the long horizontal frame and further decrease forward area of the display strip and the long horizontal frame for increasing transmittance of the LED display device.

2. The device as claimed in claim 1, wherein the vertical support members are made from steel wires.

3. The device as claimed in claim 1, wherein the long horizontal frame is made from transparent material.

4. The device as claimed in claim 1, wherein the support member and the power cable assemble with each other to form a cable support member.

5. The device as claimed in claim 4, wherein the cable support member includes steel wires in a center, a power cable outside the steel wires, and a cover layer on the most outer side.

6. The device as claimed in claim 5, wherein the cover layer is made from polyvinyl chloride (PVC).
