[0019] The present utility model discloses a general display mechanism. With reference to Figure 2 and Figure 3As shown in the figure, it includes a display cover plate 1, a light guide support 2, an LED light board 3 and a back shell 4. The light guide support 2 is arranged between the display cover plate 1 and the LED light board 3. The back shell 4 covers the rear side of the LED light board 3, and the back shell 4 is fixedly connected to the display cover plate 1. A plurality of LED lights 30 are arranged on the LED light board 3. A plurality of light guide holes 20 are arranged on the light guide support 2. The light guide holes 20 correspond to the LED lights 30 one by one. The display cover plate 1 is a light-transmissive cover plate, and the display cover plate 1 covers the front side of the plurality of light guide holes 20.

[0020] In the above structure, the back shell 4 is snap-fitted and fixed to the back side of the display cover plate 1. The back shell 4 can bulge backward so as to form a receiving cavity between the back shell 4 and the display cover plate 1. The light guide support 2 and the LED light board 3 are installed in this receiving cavity. The light guide support 2 is located on the front side of the LED light board 3. The light guide holes 20 on the light guide support 2 are aligned with the LED lights 30 on the LED light board 3 one by one, so that the light emitted by the LED lights 30 directly passes through the light guide holes 20 and forms independent and clear optical signals on the display cover plate 1. Compared with the prior art, the present utility model does not need to arrange partition ribs on the display cover plate 1, which can effectively avoid the shrinkage on the front side of the cover plate. At the same time, the light guide support 2, the LED light board 3 and the back shell 4 are all detachable components. When it is necessary to replace components such as a touch panel, only the LED light board 3 needs to be replaced correspondingly. Therefore, it has better versatility.

[0021] As a preferred mode, the plurality of LED lights 30 on the LED light board 3 are all surface-mounted LED lamp beads. Specifically, there are a plurality of surface-mounted LED lamp bead assemblies on the LED light board 3, and each assembly contains 4 lamp beads, as Figure 3 shown.

[0022] In order to further improve the display effect, in this embodiment, an ITO film 5 is attached to the front side of the light guide support 2, and the ITO film 5 covers the front side of the plurality of light guide holes 20.

[0023] In this embodiment, in order to better accommodate the ITO film 5, an inner concave step portion 21 is formed on the front side of the light guide support 2 in this embodiment, and the ITO film 5 is attached within the inner concave step portion 21.

[0025] Embodiment 2

[0026] Please refer to Figure 3 , the difference between this embodiment and Embodiment 1 is that the multiple LED lamps 30 on the LED lamp board 3 are all spherical lamp beads. Further, a conductive spring 31 is sleeved outside each LED lamp 30, the LED lamp 30 and the conductive spring 31 are both disposed through the light guide hole 20, the conductive spring 31 abuts between the display cover plate 1 and the LED lamp board 3, and the conductive spring 31 is electrically connected to the LED lamp board 3.

[0027] In the above structure, based on the sleeved relationship between the conductive spring 31 and the LED lamp 30, after the two are combined, they can be directly accommodated in the light guide hole 20. While using the LED lamp 30 to display a light signal, the conductive spring 31 can transmit the touch micro-current signal of the user to the LED lamp board 3, and then the LED lamp board 3 transmits the micro-current signal to the main control board. Based on the above structure, it can be seen that the present utility model can place the conductive spring 31 and the LED lamp 30 in the light guide hole 20 at the same time, which not only rationally utilizes the space in the hole, but also achieves the technical effect of touch control.

[0028] In practical applications, the present utility model can mutually replace the two LED lamp boards in the above Embodiment 1 and Embodiment 2, so as to meet the application requirements of different types of electrical equipment.
