Abstract

A matrix type LED wall display tube device is adapted for mounting on a wall, and includes equidistantly spaced apart LEDs soldered onto circuit boards and disposed inside transparent tubes to form serially connected display tubes. The display tubes are spaced apart and secured in juxtaposition by means of interconnected bases. A programmable controller is used to achieve LED signal displays to therbey provide a display device with advantages of good displaying effects, easy installation and low costs.

Claims

1. A matrix type LED wall display tube device, including light-emitting transparent tubes, LED lighting units, bases and a controller that combine to form a tubular spaced-apart display screen.

2. The matrix type LED wall display tube device according to claim 1, wherein in said light-emitting transparent tubes and said LED lighting units, said LED lighting units include LED members arranged linearly and in pairs and are inserted in or soldered to strip-like circuit boards, said circuit boards each having two ends respectively provided with connecting terminals, said light-emitting transparent tubes including transparent tubes into which said circuit boards with said LED members are disposed.

3. The matrix type wall display tube device according to claim 1, wherein each of light-emitting transparent tubes can be connected via coupling tubes after connection of said connecting terminals so as to obtain a desired length.

4. The matrix type wall display tube device according to claim 1, wherein said light-emitting transparent tubes are secured on said bases, each of said bases being provided with equidistantly spaced apart supporting seats, each of said supporting seat being internally provided with connecting terminals so as to be connected to said connecting terminals at bottom ends of said light-emitting transparent tubes are disposed and secured in aid supporting seats, each of said bases being provided with bus terminals for serial connection with other bases;

if desired, connecting bases having bus terminals thereon can be provided to achieve serial connection among said bases.

5. The matrix type wall display tube device according to claim 1, wherein said controller includes a power source unit, a logic driver, input and output buffers, said power source unit having two polar power source ends, said logic driver having two ends respectively provided with said input and output buffers, the respective connecting ends thereof being connected to said two polar power source ends to make electrical connection, said logic driver being connected to said bases via lead wires, whereby said controller can, via input settings, control the entire light emitting screen composed of said light-emitting transparent tubes.
