Technical Field

[0001] The utility model relates to the technical field of IC binding, in particular to an IC binding device for an LCD screen. Background Art

[0002] As the name suggests, COG packaging in LCD technology reduces system costs by directly mounting the LCD driver on the display. This technology, essentially chip-on-glass, directly packages the driver IC onto the LCD glass using anisotropic conductive adhesive (ACF), interconnecting and encapsulating the driver IC's conductive bumps with the transparent ITO conductive pads on the LCD glass to illuminate the screen. The main advantage of this technology over COB technology is that it reduces the number of traces and layers on the PCB, thereby reducing the size and complexity of the board. Compared to traditional packaging methods, LCD products are thinner, more reliable, more flexible, and have a simpler production process, making it an economical and reliable technology for LCD displays.

[0003] The unique feature of COG packaging is that the driver IC is bonded to the LCD screen. This requires more space on the LCD screen to bond the IC. However, some products lack sufficient space for IC placement due to their overall structure. In this case, a device is needed that can provide an IC bonding area and connect the IC to the LCD screen so that the IC can drive the screen, thus fulfilling the COG packaging function without significantly increasing costs. Therefore, an IC bonding device for LCD screens is proposed to address this problem. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figure 1 The present invention provides an embodiment of an IC binding device for an LCD screen, comprising a whole machine housing 1, an LCD screen body 2 fixedly connected to the inner wall of the whole machine housing 1, and a connection end of the LCD screen body 2 extending to the outside of the whole machine housing 1. By following the logical relationship of the LCD screen, the electrode terminals for driving the internal pixels are led out to the outside of the whole machine housing 1, so that the connection end of the LCD screen body 2 can be accessed from the outside.

[0030] Reference Figure 1 - Figure 2The connection end of the LCD screen body 2 is provided with an external component 3, which includes an ITO glass 31. An electrode line 32 is provided on the surface of the ITO glass 31. The electrode line 32 is fixedly connected to the connection end of the LCD screen body 2 via a flexible conductive paper 33. The ITO glass 31 is transparent conductive glass. The number of electrode lines 32 is arranged according to the logic requirements of the LCD screen. The flexible conductive paper 33 is used to connect the connection end of the LCD screen body 2 to the electrode line 32, and the flexible conductive paper 33 is bendable.

[0031] Reference Figure 1 - Figure 2 A conductive pad 34 is provided on the surface of the ITO glass 31, and the conductive pad 34 is fixedly connected to the end of the electrode line 1 32. An IC body 35 is provided on the surface of the conductive pad 34, and the conductive bumps of the IC body 35 are bound according to the position of the corresponding conductive pad 34. A driving pad 36 is fixedly connected to the surface of the ITO glass 31, and the driving pad 36 is fixedly connected to the conductive pad 34 through the electrode line 2 39. The electrode line 2 39 is fixedly connected to the surface of the ITO glass 31, and an FPC 37 is fixedly connected to the surface of the driving pad 36. One end of the FPC 37 is crimped on the driving electrode of the driving pad 36, and the other end is connected to the external driving device. The electrode line 2 39 connects the FPC 37 and the IC body 35 together for signal transmission. The IC body 35 is connected to the connection end of the LCD screen body 2 through the conductive pad 34, the electrode line 1 32, and the flexible conductive paper 33, thereby realizing external driving of the LCD screen similar to the COG mode under the condition of small host space.

[0032] Reference Figure 2 - Figure 3The surface of the ITO glass 31 is provided with two groups of symmetrically arranged mounting grooves 38, which are used to accommodate and install subsequent fixing components 4. The interior of the mounting groove 38 is provided with a fixing component 4, which includes a slide 41. The slide 41 is elastically connected to the inner wall of the mounting groove 38 through a return spring 42. The return spring 42 is used to provide elastic support for the slide 41, so that the slides 41 in the two groups of mounting grooves 38 move toward each other. The interior of the mounting groove 38 is fixedly connected to a guide rod 43, which passes through and is slidably connected to the side wall of the slide 41. The guide rod 43 is used to guide the slide 41, and the Shudie slide 41 moves stably inside the mounting groove 38. The side wall of the slide 41 is fixedly connected to a connecting rod 44, and the end of the connecting rod 44 is fixedly connected to a clamping plate 45. The bottom surface of the clamping plate 45 is provided with a groove 46, and the inner wall of the top of the groove 46 is set to an inclined shape. The connecting rod 44 connects the clamping plate 45 and the slide 41 together so that the two move synchronously. The universal clamping plate 45 contacts both sides of the IC body 35 and allows both sides of the IC body 35 to enter the groove 46. The surface of the IC body 35 is squeezed by the inside of the inclined groove 46, providing the IC body 35 with a downward force, so that the IC body 35 is stably installed on the conductive pad 34, which is convenient for the installation of the IC body 35.

[0033] Working Principle: To install the IC body 35, the operator simply pushes the clamps 45 in the two mounting grooves 38 toward each other. The clamps 45 drive the connecting rod 44 and the slide 41 to slide along the guide rod 43 within the mounting groove 38. This compresses the return spring 42 and accumulates elastic potential energy. When the two clamps 45 are close together, the top inner wall of the groove 46 no longer exerts pressure on the IC body 35. The operator can now place the IC body 35 on the conductive pad 34, aligning the conductive bumps of the IC body 35 with the conductive pad 34. The operator then releases the force on the clamps 45. The return spring 42 releases its elastic potential energy and pushes the slide 41 along the guide rod 43 away from its initial position, thereby driving the connecting rod 44 and clamps 45. Because the top inner wall of the groove 46 is inclined, as the clamps 45 move, the top inner wall of the groove 46 exerts downward pressure on the IC body 35, ensuring a stable installation on the conductive pad 34. The installation process of the IC body 35 is made simple and quick, and no additional fixing tools or materials are required, thereby greatly improving the installation efficiency and stability.

[0034] Furthermore, the presence of flexible conductive paper 33 makes the connection between the connection end of LCD screen body 2 and electrode line 1 32 more reliable. Flexible conductive paper 33 not only has excellent electrical conductivity but can also bend and deform to accommodate LCD screen bodies 2 of varying shapes and sizes. This design allows the device to be highly flexible and versatile in adapting to various LCD screens. By connecting FPC 37 and IC body 35 together via electrode line 2 39, fast and stable signal transmission is achieved. Simultaneously, one end of FPC 37 is crimped onto the drive electrode of drive pad 36, while the other end is connected to an external drive device, allowing the external drive device to conveniently control the display content and effects of LCD screen body 2.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
