The specific structure of the mounting bracket 140 and the connection manner thereof with the front case 130 and the terminal plate 150 will be described in detail below.

As an alternative embodiment, the bracket main body 141 and the light guide part 142 may be an integral component, that is, the bracket main body 141 and the light guide part 142 may be produced and processed in an integral manner, so that the bracket main body 141 and the light guide part 142 may be assembled as a single component, thereby improving the convenience of assembling the mounting bracket 140, and simultaneously reducing the space required for mounting the mounting bracket 140, which is beneficial to the narrow and thin design of the display device 100.

For example, the bracket main body 141 and the light guide portion 142 may be made of plastic, and the two may be integrally formed through a bijection molding process, wherein two material tubes of the bijection molding machine may be used to cooperate with two sets of molds to sequentially form the bracket main body 141 and the light guide portion 142, the bracket main body 141 and the light guide portion 142 formed through two molding processes are an integral piece, and a specific process flow of the bijection molding process is the prior art and is not described herein.

Since the first end of the light guide part 142 needs to receive the external signal light, that is, the signal light emitted from the front of the display side of the display device 100 needs to pass through the front case 130 into the light guide part 142 and be guided by the light guide part 142, and then emitted to the light sensing device 151 of the terminal plate 150.

The holder main body 141 may be provided with a connection part 143, a first end of the connection part 143 is connected to the holder main body 141, a second end of the connection part 143 extends toward the front case 130, and the light guide part 142 is connected to a second end of the connection part 143.
