Detailed Description

The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.

As shown in fig. 1, the embedded LED display screen includes a panel 1, a circuit board 2, and a plurality of LED display modules. The panel is divided into a first display area 1-1 and a second display area 1-2, the first display area is arranged in the middle of the panel, the two sides of the first display area are symmetrically arranged second display areas, three first mounting ports 3.1 which are arranged along the horizontal direction are arranged at the lower part of the first display area, and two second mounting ports 3.2 which are arranged up and down are arranged in each second display area. The back of panel still is equipped with first trip 1.1, second trip 1.2 and reference column 1.3, and first trip sets up the border position at the panel back, and the second trip sets up the back at the first display area of panel, and the reference column sets up the four corners position at the panel back, and embedded LED display screen realizes the installation through first trip and reference column and fixes, and the circuit board passes through the second trip and installs at the panel back. The first mounting opening and the second mounting opening are both rectangular, and the second mounting opening is larger than the first mounting opening.

Every LED display module includes reflection lid 4, encapsulation and covers PCB board 5 at the back, sets up at the positive LED luminous element of PCB board, and the system has a plurality of reflection chambeies (omitting in the picture) that are the dot matrix form and distribute on the reflection lid, and LED luminous element on the PCB board imbeds the reflection chamber one by one, and the front of reflection lid is still pasted the diffusion barrier (omitting in the picture), and the back of PCB board is equipped with pin 6.

The LED display modules are respectively installed in the first installation port and the second installation port, the sizes of the LED display modules are respectively matched with the sizes of the installation ports, and the LED display modules are electrically connected with the circuit board. The reflective cover of each LED display module is fixed to the panel by epoxy glue dispensing (the glue dispensing position is shown as part C in fig. 2), and each reflective cover is fixed to the panel by at least 4 glue dispensing. The utility model discloses during production, directly pack into LED display module for the panel, because LED display module assembles production respectively and accomplishes solid sealing in advance (unqualified module is got rid of in advance), consequently thoroughly avoided the monoblock panel to take place condemned risk to manufacturing cost has effectively been reduced.

Finally, it should be noted that the above-mentioned embodiments illustrate only specific embodiments of the invention. Obviously, the present invention is not limited to the above embodiments, and many variations are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the invention should be considered as within the scope of the invention.
