Considering that the infrared optical signal can only penetrate through the transparent material, the material of the back plate 2 is usually set to be metal, so as to ensure the structural strength of the back plate 2, that is, the infrared optical signal cannot penetrate through the back plate 2, in order to avoid interference of the back plate 2 with the signal receiving portion 31 receiving the infrared optical signal, the signal receiving portion 31 can be disposed in the avoiding groove 22, so that after the infrared optical signal penetrates through the transparent material, the signal receiving portion 31 is directly irradiated. In some other embodiments, the signal receiving portion 31 may be at least partially disposed in the back plate 2, for example, a mounting hole 21 is formed on a bottom of the avoidance groove 22, the signal receiving portion 31 passes through the mounting hole 21 to extend into the avoidance groove 22, so as to reduce a mounting space required by the signal receiving portion 31, make connection between the signal receiving portion 31 and the avoidance groove 22 more stable, and, in order to avoid interference of the back plate 2 with the signal receiving portion 31 receiving the infrared optical signal, the signal receiving portion 31 is exposed at a notch of the avoidance groove 22.
Because the signal receiving portion 31 is configured to convert an infrared optical signal into an electrical frequency signal and output the electrical frequency signal, the signal receiving device 3 further includes a circuit board 32, at this time, an end of the signal receiving portion 31, which is far away from the display screen 1, can be exposed to the mounting hole 21 to be electrically connected with the circuit board 32, and can be fixedly connected with the circuit board 32, so as to increase the stability of connection between the signal structure portion and the circuit board 32, and simultaneously, a positioning structure 4 and/or a fixing structure 5 are/is arranged between the circuit board 32 and the back board 2, and a positioning structure 4 and/or a fixing structure 5 are/is arranged on the bottom of the avoidance groove 22, so that the positioning structure 2 is fixedly connected with the back board 32, and the position of the circuit board 32 is prevented from being deviated from being fixed with the circuit board 32, and the position of the back board 2 is prevented from being connected with the circuit board 32, and the position of the circuit board 32 is correspondingly arranged on the bottom of the avoidance groove 22, and the signal receiving portion is further included in the circuit board 32, and the signal receiving portion 31 is electrically connected with the circuit board 32.
