The first frame 21 can include a first connecting segment 211, a second connecting segment 212, a third connecting segment 213, and a fourth connecting segment 214. The first connecting segment 211 can be connected to the ground side of the display screen 10. The second connecting segment 212 can be connected to the first connecting segment 211. The third connecting segment 213 can be connected to the second connecting segment 212. In the height direction of the display device, the third connecting segment 213 can be disposed on the side of the first connecting segment 211 away from the display screen 10. The fourth connecting segment 214 can be connected to the third connecting segment 213. In the thickness direction of the display device, the fourth connecting segment 214 can be disposed apart from the display screen 10. In the thickness direction of the display device, the first connecting segment 211 and the second connecting segment 212 can be respectively disposed apart from the fourth connecting segment 214. The first connecting segment 211, the second connecting segment 212, the third connecting segment 213, and the fourth connecting segment 214 can enclose the first accommodating cavity 21a. The first accommodating cavity 21a can be open on the side in the +Z-axis direction.

[0073] In some examples, the first connecting segment 211 of the first frame 21 can be connected to the back shell of the display screen 10 by a bolt.

[0074] In some examples, the frame body can further include a second frame 22 (see Figure 1 and Figure 2 As shown, the second frame 22 can be disposed apart from the first frame 21 in the height direction of the display device. The second frame 22 can be connected to the top side of the display screen 10. The second frame 22 can have a second accommodating cavity 22a.

[0075] The display device can include an infrared module. The infrared module can be at least partially located in the first accommodating cavity 21a.

[0076] In some examples, as shown in Figure 2 and Figure 3 As shown, the infrared module can include a first device 31 and a second device 32. The first device 31 can emit an infrared light beam. The second device 32 can receive the infrared light beam emitted by the first device 31.

[0077] In some examples, as shown in Figure 2 and Figure 3 As shown, the frame body can include a first frame 21 and a second frame 22. The infrared module can include a first device 31 and a second device 32. The first device 31 can be located in the first accommodating cavity 21a of the first frame 21. The second device 32 can be located in the second accommodating cavity 22a of the second frame 22.

[0078] In some other examples, the frame body can further include a left frame and a right frame in addition to the first frame 21 and the second frame 22. The infrared module can include two first devices 31 and two second devices 32. One first device 31 can be arranged in the first accommodating cavity 21a of the first frame 21. One first device 31 can be arranged in the left frame of the display screen 10. One second device 32 can be arranged in the second accommodating cavity 22a of the second frame 22. One second device 32 can be arranged in the right frame of the display screen 10.

[0079] In some other examples, the infrared module can be a one-piece. The one-piece can emit an infrared light beam. The one-piece can also receive an infrared light beam. The frame body can only include the first frame 21. The one-piece can be arranged in the first accommodating cavity 21a of the first frame 21.

[0080] In some examples of the present application, referring to Figure 4 The infrared module can further include a connecting line 33. The connecting line 33 can connect the first device 31 and the second device 32. The connecting line 33 can be used to transmit electrical signals between the first device 31 and the second device 32.

[0081] Exemplarily, the connecting line 33 can be a flexible flat cable (FFC). The flexible flat cable can be arranged on one side of the display screen 10 in the width direction of the display device. The first device 31 can be arranged in the first accommodating cavity 21a of the first frame 21. The second device 32 can be arranged in the second accommodating cavity 22a of the second frame 22. The flexible flat cable can be connected to the first device 31 through the first socket 34. The flexible flat cable can be connected to the second device 32 through the second socket 35.

[0082] In some examples of the present application, the infrared module can further include a circuit board 36 (see Figure 3 The circuit board 36 can be arranged in the first accommodating cavity 21a. The circuit board 36 can be arranged on the side of the first device 31 away from the light filter body 41. The circuit board 36 can be connected to the first device 31.

[0083] In some examples, when the user does not perform a touch operation, the infrared light beam emitted by the first device 31 is not blocked, the second device 32 can receive the infrared light beam emitted by the first device 31, and the circuit board 36 can determine that the user does not perform a touch operation according to the infrared light beam received by the second device 32.

[0084] In some examples, when a user performs a touch operation, such as touching the touch glass, the infrared beam emitted by the first device 31 is blocked, and the second device 32 cannot receive the infrared beam emitted by the first device 31. Since the second device 32 does not receive the infrared beam emitted by the first device 31, the circuit board 36 can determine that the user has performed a touch operation.

[0085] The display device may include a light filter bar 40 (see...) Figure 3 (As shown). In some examples, the filter strip 40 can filter out beams other than the infrared beam to ensure that the infrared module can detect the contact of a finger or stylus.

[0086] See Figure 5 As shown, the filter strip 40 may include a filter body 41. The filter body 41 may be disposed between the display screen 10 and the first frame 21.

[0087] The filter body 41 can be disposed between the fourth connecting segment 214 of the first frame 21 and the display screen 10. This arrangement allows the filter body 41 to filter out light beams other than the infrared light beam from the first device 31.

[0088] In some examples, the light filter body 41 is pressed between the fourth connecting segment 214 of the first bezel 21 and the touch glass of the display screen 10. In the height direction of the display device, the end of the light filter body 41 that contacts the touch glass may be higher than the end of the light filter body 41 that contacts the fourth connecting segment 214.

[0089] The filter strip 40 may also include a blocking portion 42. The blocking portion 42 may be connected to the filter body 41. The blocking portion 42 may block the first receiving cavity 21a. In some examples, the blocking portion 42 may block the opening of the first receiving cavity 21a on one side in the +Z axis direction, so that water between the display screen 10 and the filter strip 40 will not enter the first receiving cavity 21a of the first frame 21.

[0090] It should be noted that the water on the display device can be water left behind when wiping dust off the display screen 10 or the filter strip 40. Alternatively, the water on the display device can also be water that appears on the display screen 10 due to humid weather.

[0091] The shielding portion 42 may have a guiding surface 4221. The guiding surface 4221 may be configured to drain water between the display screen 10 and the filter strip 40 to the outside of the display device. With this configuration, water between the display screen 10 and the filter strip 40 will not enter the first receiving cavity 21a of the first frame 21, so that the infrared module will not be damaged, thereby protecting the infrared module.

[0092] In some embodiments of this application, see Figure 5As shown, the shielding portion 42 can include a first plate 421 and a second plate 422.

[0093] The first plate 421 can be connected with the light filtering body 41. In some examples, the first plate 421 can be connected with the light filtering body 41 on one side in the -Z axis direction.

[0094] The first plate 421 can be disposed on a side of the display screen 10 facing the light filtering body 41 in the thickness direction of the display device.

[0095] A first flow channel can be formed between the first plate 421 and the display screen 10. In some examples, the first plate 421 can be in contact with the touch glass of the display screen 10. A gap between the first plate 421 and the touch glass can form the first flow channel.

[0096] One end of the second plate 422 can be connected with the first plate 421.

[0097] The second plate 422 can be disposed on a side of the display screen 10 facing the first bezel 21 in the thickness direction of the display device. In some examples, the second plate 422 can be disposed on a side of the first connecting segment 211 of the first bezel 21 facing away from the display screen 10 in the thickness direction of the display device.

[0098] Referring to Figure 5 and Figure 6 As shown, the guide surface 4221 can be disposed on a side of the second plate 422 facing the display screen 10.

[0099] The guide surface 4221 can form a second flow channel 4222 (see Figure 3 ) between the guide surface 4221 and the display screen 10. In some examples, the second flow channel 4222 can be in communication with the first flow channel. In this way, water on the display screen 10 flows along the touch glass into the first flow channel. The water in the first flow channel can flow into the second flow channel 4222. The guide surface 4221 can guide the water in the second flow channel 4222 to the outside of the display device.

[0100] One end of the second plate 422 facing away from the first plate 421 can be in abutment with the first bezel 21. In some examples, one end of the second plate 422 facing away from the first plate 421 can be in abutment with the second connecting segment 212.

[0101] In the height direction of the display device, the second plate 422, the light filtering body 41 and the first plate 421 can collectively cover the first accommodating cavity 21a. In this way, the second plate 422, the light filtering body 41 and the first plate 421 can block water on the display screen 10, thereby protecting the first device 31.

[0102] In some embodiments of the present application, the shielding portion 42 can further include a third plate 423. The third plate 423 can be connected with the second plate 422. The third plate 423 can be arranged on the side of the second plate 422 facing the display screen 10. In the thickness direction of the display device, the third plate 423 can shield the guide surface 4221. In this way, the water in the second flow channel 4222 can be blocked by the third plate 423, so as to avoid the water in the second flow channel 4222 flowing into the first accommodating cavity 21a from the gap between the second plate 422 and the second connecting segment 212.

[0103] In some examples, in the width direction of the display device, the third plate 423 can abut against the second connecting segment 212. In the height direction of the display device, the third plate 423 can abut against the first connecting segment 211.

[0104] In some embodiments of the present application, the guide surface 4221 can be a guide plane or a guide curved surface.

[0105] In some examples, the guide surface 4221 can include a first end 422a and a second end 422b. The first end 422a can face the connecting line 33 in the width direction of the display device. The second end 422b can be away from the connecting line 33 in the width direction of the display device. In the height direction of the display device, the first end 422a can be arranged on the side of the second end 422b facing the display screen 10, that is, in the height direction of the display device, the first end 422a can be arranged on the side of the second end 422b in the +Z axis direction. In this way, in the height direction of the display device, the first end 422a can be higher than the second end 422b. When the water between the display screen 10 and the light filtering strip 40 flows onto the second plate 422 through the first flow channel, the water can be guided by the guide surface 4221 to flow from the second end 422b to the outside of the display device, so as to avoid the water on the second plate 422 flowing from the first end 422a to the connecting line 33, and the water flowing along the connecting line 33 to the first socket 34, causing a short circuit, thereby protecting the infrared module.

[0106] In some examples, referring to Figure 6 As shown, the cross section of the second plate 422 in the plane defined by the X axis and the Z axis can be trapezoidal. In the height direction of the display device, the thickness of the side of the second plate 422 close to the connecting line 33 can be greater than the thickness of the side of the second plate 422 away from the connecting line 33. The guide surface 4221 can be a guide plane.

[0107] Embodiment Two

[0108] Referring to Figure 7 As shown, the present application provides a light filtering strip wiping detection method, including the following steps:

[0109] S100, the display device calculates the coordinates of the preset point of the shielding area 300, and calculates the width of the shielding area 300 in the width direction of the display device and the height of the shielding area 300 in the height direction of the display device.

[0110] As shown in FIG. 1, the width direction of the display device can be the X-axis direction. The height direction of the display device can be the Z-axis direction. Figure 8
