[0028] See also Figure 1-2 The display panel waterproof structure includes a light board 1, a shading member 2, a light guide member 3, a panel 4 and a sealing gasket 5. The light board 1, the shading member 2, the light guide member 3, the sealing gasket 5 and the panel 4 are stacked in sequence, and the sealing gasket 5 can prevent liquid from passing through the panel 4 and contacting the light board 1.

[0029] See also Figure 1-2 The light board 1 includes a circuit board 13 and a light bulb 14. The light bulb 14 is welded on the circuit board 13. The light bulb 14 can be an LED light. The light bulb 14 is arranged on the circuit board 13 at intervals. In some embodiments, there are at least three light bulbs 14, and the light bulbs 14 are arranged on the circuit board 13 at equal intervals. The light color of each light bulb 14 is different. The light shielding member 2 is made of an opaque material, and the surface of the light shielding member 2 can also be painted black. The light shielding member 2 can prevent the light emitted by two different light bulbs 14 from crossing. The light shielding member 2 is provided with at least two light-transmitting through holes 21. The light-transmitting through holes 21 are cylindrical. The central axis of the light-transmitting through holes 21 is in the same direction as the light bulb 14. Light can pass through the light-transmitting through holes 21. The light-transmitting through holes 21 correspond to the light bulbs 14 one by one. The light bulbs 14 extend into the light-transmitting through holes 21.

The light guide columns 32 are arranged on the surface of the main body 31 at intervals. The light guide columns 32 are cylindrical, and the light guide columns 32 correspond to the light-transmitting through holes 21 one by one. The light guide columns 32 and the corresponding light-transmitting through holes 21 are on the same optical path. Specifically, the central axis of the light-transmitting through hole 21 is in the same direction as the light bulb 14, and the central axis of the light-transmitting through hole 21 coincides with the central axis of the light guide column 32. The light emitted by the light bulb 14 can pass through the light-transmitting through hole 21, the main body 31, and the light guide columns 32 in sequence to reach the outside of the light guide 3.

[0032] See also Figure 1-3The panel 4 is provided with at least two through holes 41, which are used for passing light. The through holes 41 correspond to the light guide column 32 one by one. The light guide column 32 extends into the through holes 41. The light guide column 32 can pass through the through holes 41 and be exposed outside the panel 4. The end of the light guide column 32 may not exceed the panel 4, and the end of the light guide column 32 may also be flush with the outer surface of the panel 4. The light emitted by the bulb 14 can pass through the light-transmitting through hole 21, the main body 31, and the light guide column 32 in sequence to reach the outside of the panel 4. The sealing gasket 5 plays a waterproof role, and the sealing gasket 5 can be made of rubber or silicone. The sealing gasket 5 is sandwiched between the panel 4 and the main body 31. The sealing gasket 5 is provided with a plurality of first clearance holes 51. The light guide column 32 passes through the first clearance holes 51. Preferably, the diameter of the light guide column 32 is the same as the aperture of the first clearance hole 51, or the light guide column 32 and the first clearance hole 51 are interference fit. The narrow gap between the light guide column 32 and the panel 4 is filled with a sealing gasket 5, and liquid cannot pass through the narrow gap between the light guide column 32 and the panel 4. The side of the light guide column 32 away from the light board 1 is flush with the surface of the panel 4, ensuring that the surface of the panel 4 is flat and smooth.

[0033] The present application sets a sealing gasket 5 between the panel 4 and the main body 31 light guide 3, and clamps the sealing gasket 5 by the panel 4 and the light guide 3, so that the sealing gasket 5 can block the gap between the panel 4 and the light guide 3, preventing liquid from contacting the light board 1 through the perforation 41 and causing a short circuit in the light board 1, so that the waterproof structure of the display panel meets the IP67 waterproof requirement.

[0034] See also Figure 2-3 , a button 11 is provided on the light board 1, a key hole is provided on the panel 4, and the button 11 extends toward the key hole.

The number of key holes is consistent with the number of buttons 11, and the key holes and buttons 11 correspond one to one. The sealing gasket 5 is provided with a protective cover 52 corresponding to the button 11. The protective cover 52 is sleeved on the outside of the button 11, and the protective cover 52 passes through the key hole. The protective cover 52 is exposed outside the panel 4. The protective cover 52 can prevent liquid from contacting the light board 1 through the key hole, wherein the button 11 can pass through the key hole and be exposed outside the panel 4, and the button 11 may not exceed the key hole. The protective cover 52 has a certain thickness. For example, if the button 11 does not exceed the key hole, the protective cover 52 passes through the key hole and is exposed outside the panel 4. The user can press the button 11 by pressing the protective cover 52.

[0035] See also Figure 2-3The light guide 3 is provided with a second clearance hole 33, and the button 11 passes through the second clearance hole 33. When the number of buttons 11 is multiple, the number of second clearance holes 33 is also multiple, and the buttons 11 correspond to the second clearance holes 33 one by one. The second clearance hole 33 can limit the button 11, limit the shaking of the button 11 along the length direction of the light board 1, and can also protect the button 11. The protective cover 52 is located on the side of the second clearance hole 33 facing away from the light board 1, and the light guide 3 and the panel 4 are matched and clamped on both sides of the edge of the protective cover 52, so as to position the protective cover 52. The main body 31 is provided with a slot 311, and the shading member 2 is embedded in the slot 311. The slot 311 is used to limit the shading member 2 and fix the shading member 2, wherein the shading member 2 can be fixed to the slot 311 by interference fit, and the shading member 2 can also be fixed to the slot 311 by glue.
