[0079] Reference Figure 1-Figure 3 The present application embodiment provides a display device, including a back plate 200, a screen body 500, a front shell 100, a bracket 400 and a signal receiving component 300, wherein, with reference to Figure 3 The back plate 200 is formed with a accommodating cavity 210 for accommodating structures such as optical modules. The back plate 200 also has a mounting portion 220, which is arranged along the circumference of the back plate 200. The back plate 200 is connected to the front shell 100 through the mounting portion 220; the screen body 500 has a light emitting surface and a backlight surface opposite to the light emitting surface. The screen body 500 is arranged on the back plate 200, and the backlight surface of the screen body 500 faces the accommodating cavity 210.

[0080] For example, continue to refer to Figure 3 The front shell 100 may include a first mounting plate 110 and a second mounting plate 120 connected to each other. The first mounting plate 110 is arranged on the outer side of the mounting portion 220, and the second mounting plate 120 extends toward the inner side of the first mounting plate 110. The front shell 100 and the back plate 200 cooperate with each other to fix the screen body 500. The second mounting plate 120 is also provided with a connecting hole 121.

[0081] Reference Figure 2-Figure 4The bracket 400 is installed on the surface of the back plate 200 away from the front shell 100. The signal receiving component 300 includes a sensor 320 and a light guide 310. The sensor 320 is arranged on the bracket 400, and the light guide 310 is connected to the bracket 400 so that the light guide 310 is relatively fixed to the back plate 200 through the bracket 400.

[0082] Reference Figure 3 At least a portion of the light guide 310 is inserted between the first mounting plate 110 and the mounting portion 220, a first end of the light guide 310 is passed through the connecting hole 121, and a second end of the light guide 310 faces the sensing element 320, so that the light guide 310 can receive an optical signal from one side of the display surface of the screen 500 through the connecting hole 121, and transmit the optical signal to the sensing element 320, so that the sensing element 320 obtains the optical signal through the light guide 310.

[0083] Reference Figure 3 and Figure 5 In some possible implementations, the light guide 310 may include a receiving portion 311, an extending portion 312, and a fixing portion 313 connected to each other; wherein the receiving portion 311 may be disposed between the first mounting plate 110 and the mounting portion 220, and an end of the receiving portion 311 away from the extending portion 312 forms a first end of the light guide 310, so as to receive an optical signal from one side of the display surface of the screen 500 through the receiving portion 311;

[0084] The first end of the extension portion 312 is connected to the receiving portion 311, and the second end of the extension portion 312 extends away from the first mounting plate 110 in a direction away from the second mounting plate 120; the fixing portion 313 can be connected to the second end of the extension portion 312, so that the optical signal from the display surface side of the screen body 500 can be transmitted to the sensing element 320 through the receiving portion 311, the extension portion 312 and the fixing portion 313 in sequence, so that the light guide 310 realizes the optical signal transmission process; the fixing portion 313 can be configured to be detachably connected to the bracket 400, so as to facilitate the disassembly and assembly process between the fixing portion 313 and the bracket 400.

[0085] Exemplarily, one of the fixing portion 313 and the bracket 400 may be provided with a sliding block 430, and the other of the fixing portion 313 and the bracket 400 may be correspondingly provided with a sliding groove 3131, and the sliding groove 3131 may extend along a first direction, and the first direction is parallel to the screen body 500; the sliding block 430 may be slidably arranged in the sliding groove 3131 along the first direction, so that the fixing portion 313 can be fixed to or detached from the bracket 400 through the sliding block 430 and the sliding groove 3131, thereby allowing the light guide 310 to be detachably connected to the bracket 400.

[0086] Reference Figure 5 and Figure 6For example, the fixing portion 313 may be provided with a sliding groove 3131, the bracket 400 may be provided with a sliding block 430, the number of the sliding blocks 430 may be set to two, the two sliding blocks 430 may be spaced apart along the second direction, and the second direction is parallel to the screen body 500; and the sliding block 430 may also be provided with a protrusion 431, and the protrusion 431 may be protruded toward a third direction, and the third direction is perpendicular to the screen body 500, and the first direction, the second direction and the third direction are arranged perpendicularly in pairs.

[0087] It is easy to understand that on the same sliding block 430, the number of protrusions 431 can be set to one or more. When the number of protrusions 431 is set to multiple, some of the multiple protrusions 431 can protrude toward the back plate 200, and the remaining protrusions 431 can protrude away from the back plate 200, so as to make the sliding process of the sliding block 430 in the sliding groove 3131 more stable.

[0088] Reference Figure 7 When the fixing portion 313 needs to be connected to the bracket 400, the two sliding blocks 430 are inserted into the corresponding sliding grooves 3131, so that the two sliding blocks 430 can slide in the corresponding sliding grooves 3131 along the first direction, so that the connection between the fixing portion 313 of the light guide 310 and the bracket 400 is more stable; and, by providing a protrusion 431 on the sliding block 430, the protrusion 431 can play a certain limiting role, thereby reducing the possibility of the sliding block 430 being separated from the sliding groove 3131, and improving the stability of the connection between the fixing portion 313 and the bracket 400.

[0089] Exemplarily, the fixing portion 313 is provided with a sliding groove 3131, and the bracket 400 is provided with a sliding block 430. The sliding block 430 may be provided with an abutment joint 440 for abutting the bracket 400. The abutment joint 440 may be connected to the sliding block 430 by bonding or snapping, or the abutment joint 440 may also be integrally provided on the sliding block 430. When it is necessary to connect the fixing portion 313 to the bracket 400, the sliding block 430 slides in the sliding groove 3131 along the first direction. When the fixing portion 313 is relatively fixed to the bracket 400, the abutment joint 440 can abut against the bracket 400, so that the abutment joint 440 plays a certain limiting role. In addition, by arranging the abutment joint 440 on the sliding block 430, the possibility of reverse installation of the fixing portion 313 can be reduced.

[0090] And / or, the bracket 400 is provided with a sliding block 430, the fixed part 313 is provided with a sliding groove 3131, and a limiting head 3133 for abutting the sliding block 430 can be provided in the sliding groove 3131. When the fixed part 313 needs to be connected to the bracket 400, the sliding block 430 slides along the first direction in the sliding groove 3131. When the fixed part 313 is relatively fixed to the bracket 400, the limiting head 3133 can abut against the sliding block 430, thereby utilizing the limiting head 3133 to play a certain limiting role.
