In another embodiment, the display module 120 may be other types of display modules, such as a plasma display module. The display module 120 can display a picture (not shown), which is displayed from the display surface 110u of the light-transmitting plate 110.

As shown in FIGS. 1 and 2, the fixing member 130 is fixed in the groove 110r through glue, for example. For example, the fixing member 130 is fixed on the light shielding layer 114 through adhesive. The end surface 130s of the fixing member 130 and the side wall 110w of the groove 110r are separated by a gap s. The gap s can provide an accommodation space for the deformation of the fixing member 130 and/or the light-transmitting plate 110 due to thermal expansion and contraction, so as to prevent the light-transmitting plate 110 and the fixing member 130 from squeezing each other to generate excessive internal stress.

As shown in FIG. 2, the fixing member 130 has two first engaging portions 131. As shown in FIG. 4, the movable element 140 includes a flexible portion 141, a first extending arm 142, a second extending arm 143 and two second engaging portions 144. The flexible portion 141 has a notch 141r to provide the flexible portion 141 with flexibility. As shown in FIG. 4, the notch 141r can extend to the side surface 141s of the flexible portion 141, so that the flexibility of the flexible portion 141 can be improved. In addition, the thickness t1 of the flexible portion 141 is smaller than the thickness t2 of the first extension arm 142 and the thickness t3 of the second extension arm 143, so that the flexibility of the flexible portion 141 can also be improved.

As shown in FIG. 4, the first extension arm 142 and the second extension arm 143 are connected to the flexible portion 141 and are located on two opposite sides of the recess 141r. The two second engaging portions 144 are respectively connected to the first extension arm 142 and the second extension arm 143 and are disposed oppositely. In this way, when the flexible portion 141 is deformed, the first extension arm 142 and the second extension arm 143 can be driven to move, and then the two second engaging portions 144 can be driven to move with the first extension arm 142 and the second extension arm 143.

The two second engaging portions 144 are selectively engaged with or separated from the two first engaging portions 131 through the flexibility of the flexible portion 141. For further example, as shown in Figure 4, the first extension arm 142 includes a connecting portion 1421 and a free end 1422. The connecting portion 1421 is connected to the flexible portion 141, and the second extension arm 143 includes a connecting portion 1431 and a free end. 1432, wherein the connecting portion 1431 is connected to the flexible portion 141.

Since the flexible portion 141 is flexible, when the connecting portion 1421 of the first extension arm 142 and the connecting portion 1431 of the second extension arm 143 approach each other (for example, using a user's hand or tool), The flexible portion 141 is deformed so that the free end 1422 of the first extension arm 142 and the free end 1432 of the second extension arm 143 expand outward in the direction away from each other, thereby driving the two second engaging portions 144 to expand outward in the direction away from each other , To break away from the two first engaging portions 131. When the movable part 140 is separated from the fixed part 130, the movable part 140 and the fixed part 130 can be separated, so that the light sensing module 150 is detached from the light-transmitting plate 110 along with the movable part 140.

After releasing the connecting portion 1421 of the first extension arm 142 and the connecting portion 1431 of the second extension arm 143, the flexible portion 141 returns to its free state, so that the first extension arm 142, the second extension arm 143 and the second extension arm 142 are engaged with each other. The portion 144 returns to the initial position (the position shown in FIG. 1 ), so that the two second engaging portions 144 are respectively engaged with the two first engaging portions 131.

In another embodiment, the number of the first engaging portion 131 may be one, and the number of the second engaging portion 144 and the number of extension arms may be the same as the number of the first engaging portion 131. As long as the movable part 140 and the fixed part 130 are detachably connected, the embodiment of the present invention does not limit the number of the first engaging portion 131, the number of the second engaging portion 144, and/or the number of extension arms.

As shown in FIGS. 2 and 4, an accommodating groove 140r is formed between the first extending arm 142, the second extending arm 143 and the flexible portion 141, and the light sensing module 150 can be fixed in the accommodating groove 140r. For example, the movable member 140 has at least one protrusion 145, which is configured to The flexible portion 141 protrudes from the bottom surface of the receiving groove 140r. The light sensing module 150 has at least one recessed portion 150r, and the recessed portion 150r can be detachably combined with the protrusion 145 to temporarily fix the relative position of the movable member 140 and the light sensing module 150. In this way, the light sensing module 150 can be disassembled from the movable part 140 to process the light sensing module 150 separately, or to assemble another light sensing module 150 to the movable part 140.

As shown in FIGS. 1 and 3, the light sensing module 150 includes a circuit board 151, a light sensor 152, and electronic components 153.
