Description

Technical Field

[0001] The utility model belongs to the field of LED display, relates to an LED digital tube, and particularly relates to a full-touch induction type LED digital tube. Background Art

[0002] An LED digital tube lights up a light-emitting window on a plastic shell through a light-emitting lamp core on a circuit board, and displays specific numbers and patterns through a display mask. To meet market demands, an LED digital tube with a touch display function is favored by people. To achieve the touch display function, the existing method is to set conductive parts such as springs at the light-emitting window, and send a command to the circuit board by touching and pressing the conductive part area, thereby lighting up the light-emitting lamp core. This method has some drawbacks in actual use, as follows:

[0003] 1. It is necessary to touch a specified area of the display mask to achieve lighting. The touch operation is not very convenient and is very prone to misoperation, resulting in multiple operations.

[0004] 2. During continuous use, conductive parts such as springs are prone to deformation, displacement, etc., resulting in the failure of the touch induction lighting function.

[0005] 3. It is necessary to set a touch window near the light-emitting window to cooperate with conductive parts such as springs, resulting in a certain impact on the display effect. Summary of the Invention

[0006] Object of the Invention: In order to overcome the deficiencies in the prior art, the utility model provides a full-touch induction type LED digital tube, which not only realizes the full-contact touch induction of the display area, but also does not need to contact the conductive medium, preventing the conductive medium from deforming, displacing, etc., and ensuring the continuous use effect of the touch induction lighting function.

[0007] Technical Solution: To achieve the above object, the utility model provides a full-touch induction type LED digital tube, including a plastic shell, a circuit board and a display mask. The plastic shell is provided with a light-emitting window. The display mask includes an outer mask part and an inner mask part. The outer mask part and the inner mask part are connected by a conductive silver glue ring. The inner mask part is located above the light-emitting window. A PEDOT layer is provided above the inner mask part. The PEDOT layer is in contact with the conductive silver glue ring. A conductive ring groove is provided on the plastic shell around the light-emitting window. A conductive medium is provided in the conductive ring groove. The bottom end and the top end of the conductive medium are respectively connected to the circuit board and the conductive silver glue ring.

[0008] Further, the conductive medium is a conductive foam or a conductive spring, both of which have good elastic functions and can achieve good and stable reset.

[0009] Furthermore, the top surfaces of the outer film portion, the conductive silver paste ring, and the PEDOT layer are on the same horizontal plane.

[0010] Furthermore, the conductive silver paste ring has a square ring structure.

[0011] The design principle of the present utility model is as follows: By adding a PEDOT layer and a conductive silver paste ring, on the one hand, the PEDOT layer will not affect the display effect of the display film, and on the other hand, the touch operation can be transmitted to the conductive medium through the conductive silver paste ring without contacting the conductive medium.

[0012] Beneficial effects: Compared with the prior art, the present utility model has the following advantages:

[0013] 1. As long as the inner film portion is touched, lighting can be achieved, realizing full-contact touch of the light-emitting area of the display film, and there will be no situation where misoperation cannot light up, reducing the operation difficulty and improving the operation convenience.

[0014] 2. The entire touch operation does not need to contact the conductive medium, preventing situations such as deformation and displacement of the conductive medium, and ensuring the continuous use effect of the touch induction lighting function.

[0015] 3. There is no need to set a touch window near the light-emitting window, ensuring the integrity of the light-emitting window and guaranteeing the light-emitting effect. BRIEF DESCRIPTION OF THE DRAWINGS
