Abstract
Description
Technical Field
[0001] This invention relates to the field of touch screen technology, and more particularly to a micro-bezel ultra-thin ITO touch screen. Background Technology
[0002] A touchscreen, also known as a touch panel, is a sensor-based liquid crystal display device that can receive input signals from touch. When a graphic button on the screen is touched, the haptic feedback system on the screen can drive various connected devices according to a pre-programmed program. It can replace mechanical button panels and create vivid audio-visual effects through the liquid crystal display. As a latest computer input device, the touchscreen is currently the simplest, most convenient, and most natural way for humans to interact with computers.
[0003] Existing ITO touchscreens generally consist of two parts: a touch panel and a display panel. When assembling an ITO touchscreen onto a mobile phone, the display panel is usually installed inside the phone case first, and then the touch panel is glued and fixed to the phone case. While a certain gap is maintained between the touch panel and the display panel, they are also separated, making the phone susceptible to bumps and knocks during prolonged use. In such cases, the touch panel usually separates from the phone case. However, with continuous investment and improvement in installation strength, existing touch panels can withstand higher levels of impact. However, the display panel inside the phone case has not been reinforced with stronger fixing strength, which can easily lead to the touch panel remaining intact while the display panel becomes loose or damaged in the event of an impact, thus reducing the phone's lifespan and making it inconvenient to repair the display panel.

[0030] See Figure 1-12 This invention provides a micro-bezel ultra-thin ITO touchscreen, comprising a touch panel 1 and a display panel 4. The touch panel 1 is disposed on one side of the display panel 4, and an upper bezel 3 and a lower bezel 2 are fitted onto the touch panel 1, with the upper bezel 3 and the lower bezel 2 being snapped together. The display panel 4 is disposed inside a bottom frame 5 and is snapped together by a sleeve 9. The bottom frame 5 is connected to the back of the upper bezel 3 and the lower bezel 2. A rotating head 7 and a limiting strip 6 are connected to both the upper bezel 3 and the lower bezel 2, and the limiting strip 6 and the rotating head 7 are staggered. A groove 51 is formed inside the bottom frame 5, and the limiting strip 6 is disposed in the groove 51. The back of the rotating head 7 passes through the bottom frame 5 and is snapped onto the bottom frame 5.
[0031] The bottom frame 5 has a groove 51 and an opening groove 52 inside, and the groove 51 and the opening groove 52 are staggered. The groove 51 has a limiting strip 6 inside, and the opening groove 52 has a rotating head 7 inside. The bottom frame 5 has an injection hole 53 for injecting heat-conducting adhesive on the back, and the injection hole 53 is connected to the groove 51. The space formed between the groove 51 and the limiting strip 6 is filled with heat-conducting adhesive.
[0032] The back of the rotating head 7 is integrally connected to an external convex plate 72, and the external convex plate 72 is provided with multiple slots 73. The rotating head 7 is engaged with the bottom frame 5 through the slots 73.
[0033] The rotating head 7 has an internal hexagonal through groove 71 inside, and multiple round holes 74 are provided on the back of the rotating head 7. The round holes 74 are connected to the internal hexagonal through groove 71 and face the slot 73.
[0034] The upper frame 3 and the lower frame 2 are both provided with recessed grooves 8. The touch panel 1 and the rotating head 7 are both located in the recessed grooves 8. The touch panel 1 is provided with notches 11 around its perimeter. The touch panel 1 is engaged with the rotating head 7 through the notches 11.
[0035] The upper frame 3 has a sleeve plate 31 embedded and fixed at its end, and the lower frame 2 has an insert plate 21 embedded and fixed at its end. The insert plate 21 is matched and inserted into the sleeve plate 31.
[0036] The limiting strip 6 has a limiting groove 61 on its side for filling with heat-conducting adhesive.
[0037] A fixing seat 12 is embedded and fixed inside the bottom frame 5. A sleeve 9 is sleeved on the fixing seat 12, and a return spring 10 is provided between the sleeve 9 and the fixing seat 12. The sleeve 9 is connected to the fixing seat 12 through the return spring 10. An adjusting bolt 92 is inserted into the sleeve 9, and the adjusting bolt 92 passes through the sleeve 9 and is connected to the threaded hole on the fixing seat 12 through thread engagement. A pressure plate 91 is integrally connected to the side of the sleeve 9.
[0038] In the process of using this invention, the touch panel 1 is first assembled with the upper frame 3 and the lower frame 2, and the upper frame 3 and the lower frame 2 are assembled together by the rotating head 7 and the insert plate 21 and the sleeve plate 31. Then, the display panel 4 is placed in the bottom frame 5. Then, the sleeve 9 and the pressure plate 91 are rotated to move the pressure plate 91 to the outside of the display panel 4. When the sleeve 9 is rotated, the return spring 10 is rotated and deformed. When the return spring 10 is deformed and reset, the sleeve 9 and the pressure plate 91 are reset. Then, the adjusting bolt 92 is rotated and moved to move the sleeve 9 and the pressure plate 91, thereby pressing the display panel 4. Then, the bottom frame 5 is aligned with the upper frame 3 and the lower frame 2, and the limiting strip 6 is matched and set in the groove 51. Then, the rotating head 7 is rotated, so that the outer protrusion 72 on the rotating head 7 is used to lock the bottom frame 5. Then, thermal conductive adhesive is injected into the groove 51 through the round hole 74 on the bottom frame 5. The thermal conductive adhesive then fills the space formed between the groove 51 and the limiting strip 6. After the thermal conductive adhesive solidifies, the limiting strip 6 and the bottom frame 5 can be stably connected, achieving the purpose of buffering, shock absorption and heat conduction. When it is necessary to install the ITO touch screen on the phone case, first reset the rotating head 7, then install the bottom frame 5 and the upper and lower frame 2 on the phone case, and then rotate the rotating head 7 90°. The outer protrusion 72 on the rotating head 7 can be snapped and fixed to the bottom frame 5 and the inner side wall of the phone case respectively. Then, thermal conductive adhesive is injected into the space formed by the phone case and the bottom frame 5 through the internal hexagonal through slot 71 on the rotating head 7. After the thermal conductive adhesive solidifies, the bottom frame 5 and the rotating head 7 can be limited, further improving the connection stability and heat conduction between the bottom frame 5, the upper and lower frame 2 and the phone case, and providing good anti-detachment and anti-cracking effects.
[0039] When disassembly is required, simply heat and melt the thermally conductive adhesive.
