Description

TECHNICAL FIELD

[0001] The present disclosure belongs to the technical field of display devices, and in particular relates to a frame assembly and a display device. BACKGROUND

[0002] Currently, the main touch display technologies are capacitive touch screen technology and infrared touch screen technology. The infrared touch screen technology forms an infrared detection network on the screen surface through infrared emitting elements and receiving sensing elements installed on the frame, and any touch object can change the infrared on the touch point to realize touch screen operation.

[0003] With the fierce competition in the display industry, cost control is an important means to improve competitiveness. By sharing the back plate of the capacitive touch screen display device and the infrared touch screen display device, the overall cost of the touch screen display device can be reduced to a certain extent, and the competitiveness can be improved.

[0004] As shown in Figure 1 , the capacitive touch screen display device can reduce the black border width by reducing the frame width or the back plate basin width. Compared with the capacitive touch screen display device, the infrared touch screen display device needs to install the infrared emitting elements and receiving sensing elements on the frame, which results in a relatively large frame width and back plate basin width of the infrared touch screen display device, i.e., the infrared touch screen display device needs to set a wider frame and back plate basin, which is difficult to achieve the purpose of sharing the back plate with the capacitive touch screen display device under a narrow black border width.

[0043] The present disclosure will be described below in combination with the drawings and with reference to specific embodiments:

[0044] In view of the technical problem that the capacitive touch screen display device and the infrared touch screen display device cannot share the back plate, the present embodiment provides a body assembly, as shown in Figures 2 to 9 The body assembly includes a frame body 100, a clamping sealing piece 200, a pressing piece 300, and a back plate 500. The frame body 100 includes a frame strip 110. The clamping sealing piece 200 is installed on the frame strip 110. The pressing piece 300 includes a pressing mounting portion 310 and a pressing portion 320 connected with the pressing mounting portion 310. The pressing mounting portion 310 is installed on the frame body 100. The pressing portion 320 and the clamping sealing piece 200 form a clamping mounting groove that is open towards the inside of the frame body 100. The clamping mounting groove is used to install a cover plate 800 and / or a display panel 900. The back plate 500 is connected with the pressing mounting portion 310, and the back plate 500 is located on the non-light-emitting side of the display panel.

[0045] The present embodiment provides a body assembly, as shown in Figures 2 to 9As shown, the clamping seal 200 and the pressing fastener 300 are arranged on the frame strip 110 respectively, and the clamping mounting groove for mounting the cover plate 800 and / or the display panel 900 is formed by the clamping seal 200 and the pressing fastener 300, so as to clamp the cover plate 800 and / or the display panel 900 on the frame strip 110, prevent the cover plate 800 and / or the display panel 900 from jumping off, and clamp the cover plate 800 and / or the display panel 900 by the clamping seal 200 and the pressing fastener 300, so that the frame strip 110 is not needed to clamp the cover plate 800 and / or the display panel 900, thereby reducing the width of the frame assembly / frame 100, reducing the black border width of the display device using the frame assembly, and meeting the requirement of narrow frame of the display device. Meanwhile, the connection of the pressing fastening part 310 and the back plate 500 can make the width of the basin of the back plate 500 not limited by the width of the frame strip 110, so that the frame assembly can be matched with the back plate 500 with a relatively narrow basin width. That is, the infrared touch screen display device and the capacitive touch screen display device using the frame assembly can use the same back plate 500 with a relatively narrow basin width, so that the back plate 500 of the infrared touch screen display device and the capacitive touch screen display device is shared, the mold types of the back plate 500 are reduced, the mold cost of the back plate 500 is saved, and the versatility of the back plate 500 is improved. In addition, the clamping mounting groove for mounting the cover plate 800 and / or the display panel 900 is formed by the clamping seal 200 and the pressing fastener 300, so that the installation process is simplified, the clamping mounting groove formed by the clamping seal 200 and the pressing fastener 300 can effectively clamp and fix the cover plate 800 and / or the display panel 900, and the stress on the cover plate 800 and / or the display panel 900 caused by the low flatness of the frame 100 due to manufacturing errors and the like can be reduced to some extent, that is, the frame assembly can be used for the infrared touch screen display device and the capacitive touch screen display device, and the defects such as light leakage caused by the poor close contact between the cover plate 800 and / or the display panel 900 and the frame assembly under the stress can be avoided.

[0046] In the related art, as Figure 1As shown, in the capacitive touch screen type display device, one side of the frame 10 is provided with a adhesive tape 20, and the capacitive touch cover plate 30 can be attached to the adhesive tape 20 through the double-sided adhesive tape 40, so as to install the capacitive touch cover plate 30 on the frame 10. At the same time, the side of the capacitive touch cover plate 30 close to the frame 10 is also sequentially stacked with the capacitive touch layer 50 and the capacitive touch display panel 60. The other side of the frame 10 is used to connect with the capacitive touch back plate 70, and the capacitive touch adhesive frame 80 and the capacitive touch backlight module 90 are arranged on the side of the capacitive touch back plate 70 close to the capacitive touch display panel 60, and the capacitive touch backlight module 90 can be supported and / or limited by the capacitive touch adhesive frame 80. Wherein, the side of the capacitive touch back plate 70 away from the capacitive touch display panel 60 is the back side of the capacitive touch back plate, and the side of the capacitive touch back plate 70 close to the capacitive touch display panel 60 is the front side of the capacitive touch back plate. The capacitive touch back plate 70 is in a basin-shaped structure, and the edge area of the back side of the capacitive touch back plate 70 can be regarded as the rim of the capacitive touch back plate 70. In the capacitive touch screen type display device, the width of the frame 10 is relatively small, so that the capacitive touch back plate 70 has a smaller rim width.

[0047] In some embodiments of the present disclosure, as shown in Figures 3 to 7 The back plate 500 is indirectly connected with the frame strip 110 through the press-solid connection part 310, and the rim width of the back plate 500 is no longer limited by the width of the frame strip 110, so that the connection position of the back plate 500 and the press-solid connection part 310 can be determined according to the design requirement, the rim width of the back plate 500 can be reduced, that is, the rim width of the back plate 500 can be reduced synchronously with the rim width of the capacitive touch back plate 70 in the capacitive touch screen type display device, so that the infrared touch screen type display device and the capacitive touch screen type display device can share the back plate 500, the mold type of the back plate 500 can be reduced, the mold cost of the back plate 500 is saved, and the versatility of the back plate 500 is improved.

[0066] In some embodiments of the present disclosure, as shown in Figures 3 to 7As shown, the clamping mounting portion includes a first clamping mounting portion 220 and a second clamping mounting portion 230, by mounting the first clamping mounting portion 220 on the front frame plate 111 and mounting the second clamping mounting portion 230 in the second slot cavity 130, the clamping sealing member 200 can be more stably mounted on the frame 100, and the clamping sealing member 200 can be further cooperated with the pressing member 300 to better clamp the cover plate 800 and / or the display panel 900, so as to avoid the cover plate 800 and / or the display panel 900 from jumping off the frame assembly.

[0067] At the same time, by mounting the first clamping mounting portion 220 on the front frame plate 111 and mounting the second clamping mounting portion 230 in the second slot cavity 130, the clamping sealing portion 210 can block the opening of the first slot cavity 120, so as to avoid dust and other foreign matters from entering the first slot cavity 120 and affecting the performance of the infrared touch module mounted in the first slot cavity 120. As shown, Figures 2 to 4 As shown, the clamping sealing portion 120 blocks the opening of the first slot cavity 120, so that the clamping sealing member 200 can seal the first slot cavity 120, and avoid dust, water vapor and other foreign matters from entering the first slot cavity 120. At the same time, by making the clamping sealing portion 210 protrude towards the inside of the frame 100 relative to the mounting plate 113, the clamping sealing portion 210 can be cooperated with the pressing portion 320 to form a clamping mounting slot opening towards the inside of the frame 100, and when clamping the cover plate 800 and / or the display panel 900 through the clamping mounting slot, the clamping sealing member 200 also blocks the gap between the cover plate 800 and / or the display panel 900 and the frame 100, so as to avoid dust, water vapor and other foreign matters from entering the inside of the display device through the gap between the cover plate 800 and / or the display panel 900 and the frame 100.
