Description

Technical Field

[0001] This disclosure relates to the field of display device technology, such as to an interactive smart flat panel. Background Technology

[0002] Interactive smart flat panels are currently widely used. They are integrated devices that combine television, computer, touch, and audio technologies to achieve human-computer interaction. Interactive smart flat panels not only have the high-definition display capabilities of traditional LCD TVs, but also possess computing power through a built-in PC (personal computer) module. They also enable interactive operation via touch technology, providing a convenient human-computer interactive experience.

[0003] like Figure 1 As shown, existing interactive smart flat panels generally include a display touch module and a frame 1' disposed around the outer periphery of the display touch module. The display touch module includes a glass cover 2', a touch screen 3', an LCD screen 4', an optical film assembly 5', and a back panel 6' arranged sequentially from the outside to the inside. Generally, a step 11' protrudes from the inner side of the frame 1', and a glass bracket 7' is disposed on the step 11'. The inner side of the glass cover 2' is bonded to the glass bracket 7' to achieve the connection between the glass cover 2' and the frame 1'. The existing design has the following defects: Due to thermal expansion and contraction of materials, the glass bracket 7' cannot contact the touch screen 3' and the LCD screen 4'. Therefore, the size of the glass cover plate 2' is larger than that of the touch screen 3' and the LCD screen 4'. The edge of the glass cover plate 2' protrudes beyond the edges of the touch screen 3' and the LCD screen 4' by a certain width so that the glass cover plate 2' can be glued to the glass bracket 7' by the adhesive layer. In order to protect the touch screen 3' and the LCD screen 4' and prevent them from directly contacting the optical film assembly 5', a middle frame 8' needs to be added. Due to the presence of the middle frame 8' and the glass bracket 7', the edge of the glass cover plate 2' has a relatively wide black border to cover the middle frame 8' and the glass bracket 7', thus affecting the display area of ​​the interactive smart flat panel. Summary of the Invention

[0024] The technical solution described in this paper will now be described in further detail with reference to the accompanying drawings.

[0025] Reference Figure 2 and 3As shown, the interactive smart flat panel disclosed in this solution includes a display touch module and a frame 1 disposed around the display touch module. The display touch module includes a cover plate 2, a touch screen 3, and an LCD screen 4. The frame 1 includes a frame body 11, which has an inner side 111 close to the display touch module. The inner side 111 has a protruding insertion part 12. The cover plate 2 includes a first side 21 and a second side 22 disposed opposite to each other. The first side 21 is the front of the cover plate 2, and the second side 22 is the back of the cover plate 2. The first side 21 and the second side 22 are connected by an edge side 23. The edge side 23 has a recessed insertion groove 24, and the insertion part 12 is inserted into the insertion groove 24. The touch screen 3 is disposed on the second side 22 and covers the second side 22. The LCD screen 4 is disposed on the side of the touch screen 3 away from the cover plate 2. By opening a slot 24 on the edge side 23 of the cover plate 2 and inserting it into the insertion part 12 of the frame 1, the cover plate 2 can be fixed on the frame 1. At the same time, the touch screen 3 and the LCD screen 4 are fully bonded and fixed on the second side 22 of the cover plate 2. This eliminates the need for a bracket to support the cover plate 2, effectively reduces the width of the black border of the interactive smart flat panel, and improves the display effect.

[0026] The front of the cover plate 2 of the interactive smart flat panel disclosed in this solution refers to the side of the cover plate 2 facing the user for displaying pictures, videos and touch operations, while the back of the cover plate 2 refers to the side of the cover plate 2 close to the LCD screen 4. That is, after the interactive smart flat panel is assembled, the user cannot see or touch the back of the cover plate 2 from the outside.

[0027] In one embodiment, the frame body 11 of the frame 1 is plate-shaped, and its thickness direction is perpendicular to the thickness direction of the cover plate 2. The insertion part 12 is disposed on one side of the frame body 11 in the thickness direction, that is, the inner side 111 of the frame body 11. By setting the frame body 11 to be plate-shaped, the width of the front visible area of ​​the frame 1 can be reduced, making the interactive smart flat panel more aesthetically pleasing.

[0028] Preferably, the depth of the insertion slot 24 is B1, where 3mm ≤ B1 ≤ 6mm, and the thickness of the frame body 11 is B2, where B2 ≤ 2mm. By setting the depth of the insertion slot 24 to be no greater than 6mm and no less than 3mm, sufficient strength can be ensured for the insertion part 12 of the cover plate 2 supported by the frame 1, while also reducing the width of the black border of the interactive smart flat panel. Furthermore, setting the thickness of the frame body 11 to be no greater than 2mm reduces the width of the front-viewable area of ​​the frame 1, improving the aesthetics of the interactive smart flat panel.

[0029] More preferably, the depth of the insertion slot 24 is B1 = 5.75 mm, and the thickness of the frame body 11 is B2 = 1.6 mm.

[0030] In one embodiment, the insertion slot 24 is arranged in a ring around the outer periphery of the cover plate 2. This design can reduce the difficulty of slotting the edge side 23 of the cover plate 2, and can also provide a structure with a larger supporting area for the insertion part 12 on the frame 1, thereby improving the support effect. In addition, it can also make the black border area of ​​the interactive smart flat panel uniform and improve the display effect.

[0031] In other embodiments, instead of providing an annular insertion groove 24 on the outer periphery of the cover plate 2, intermittent insertion grooves 24 can also be provided. For example, multiple insertion grooves 24 are spaced apart on the edge side 23 along its length direction, and the multiple insertion grooves 24 are arranged around the outer periphery of the cover plate 2.

[0032] Furthermore, the insertion groove 24 along the thickness direction of the cover plate 2 is located in the middle of the edge side 23. When the insertion groove 24 is opened on the cover plate 2, opening the insertion groove 24 in the middle of the edge side 23 can make the thickness of the cover plate 2 on both sides of the insertion groove 24 consistent, reducing the risk of deformation or breakage of the cover plate 2 at the insertion groove 24.

[0033] Preferably, the cover plate 2 is made of glass, and the edge side 23 of the glass is ground by CNC (Computer Numerical Control) with a grinding rod to form a certain concave arc surface, which is the insertion groove 24.

[0034] To improve the connection stability between the plug part 12 and the cover plate 2, the plug part 12 is adhered to the plug groove 24 with adhesive. After the adhesive is applied, it can fill the gap between the plug part 12 and the groove wall or bottom of the plug groove 24, thus adhering the plug part 12 and the cover plate 2 and effectively preventing the plug part 12 from shaking in the plug groove 24.

[0035] When attaching the connector 12, the adhesive can extend to the edge side 23, so that the inner side 111 of the frame body 11 of the frame 1 is also bonded to the edge side 23 by the adhesive. On the one hand, this can increase the connection stability between the frame 1 and the cover plate 2, and on the other hand, it can seal the gap between the cover plate 2 and the inner side 111 of the frame body 11, preventing external impurities and dust from entering the interior of the interactive smart flat panel.

[0036] Along the thickness direction of the cover plate 2, the first side surface 21 of the cover plate 2 is flush with or lower than the surface of the frame body 11. Here, the surface of the frame body 11 refers to the front of the frame body 11, that is, the side of the frame 1 that the user can see when standing facing the cover plate 2 after the interactive smart flat panel is assembled. By making the first side surface 21 of the cover plate 2 flush with or lower than the surface of the frame body 11, the edge side surface 23 of the cover plate 2 is completely concealed, allowing the frame 1 to protect the edge side surface 23 of the cover plate 2. If the cover plate 2 is made of glass, it can also prevent the glass edge corners from colliding with other hard objects and breaking, or the sharp edges from scratching the user's fingers.

[0037] In one embodiment, the touchscreen 3 is connected to the main controller (not shown in the figure) of the interactive smart flat panel via a ribbon cable 5. The ribbon cable 5 is attached to the inner side 111 of the frame body 11, and a first clearance space (not shown in the figure) is provided between the inner side 111 of the frame body 11 and the edge of the LCD screen 4 for the ribbon cable 5 to pass through. By attaching the ribbon cable 5 to the inner side 111 of the frame body 11, the ribbon cable can occupy less internal space of the interactive smart flat panel.

[0038] The interactive smart flat panel also includes a back panel 6 and an optical film assembly 7. The back panel 6 is provided with a support member 8 for fixing the optical film assembly 7. The optical film assembly 7 is spaced apart on the side of the LCD screen 4 away from the cover plate 2. A light panel 9 is provided on the side of the back panel 6 close to the cover plate 2. The light panel 9 is spaced apart from the optical film assembly 7 and is located between the back panel 6 and the optical film assembly 7.

[0039] The support member 8 can be fixed to the back plate 6 by screws or snap-fit ​​structure, so that the support member 8 can be detached relative to the back plate 6, which facilitates the assembly of the optical film assembly 7.

[0040] The backplate 6 is provided with a second clearance position 61 for the cabling 5 to pass through, and the main controller is located on the side of the backplate 6 away from the optical film assembly 7.

[0041] In this embodiment, the second clearance 61 can be a notch opened on the edge of the back plate 6, or a through hole opened on the back plate 6.

[0042] The support member 8 is provided with a third clearance position 81 corresponding to the second clearance position 61. The cable 5 can extend to the outside of the back plate 6 through the third clearance position 81 and the second clearance position 61, that is, the side of the back plate 6 away from the cover plate 2.
