Description

Technical Field

[0001] This utility model relates to the field of display panel technology, specifically to a display panel with a narrow bezel installed on electronic products. Background Technology

[0002] With the development of the consumer electronics industry, users are increasingly demanding higher standards for product design. Therefore, LCD screen manufacturers are committed to designing thinner and more aesthetically pleasing products, with narrow-bezel LCD screens, also known as full-screen or narrow-bezel displays, being one such example. These screens reduce the black border around the display, resulting in a more sophisticated and aesthetically pleasing appearance. They also make the user feel that the entire display area is filled with the screen's content, creating a more immersive and visually appealing experience.

[0003] Currently, the various components in an LCD (Liquid Crystal Display) are mainly electrically connected via pins. For example, the FPC (Flexible Printed Circuit) and the driver IC (circuit board) transmit image data and control signals via pins, which are then converted into driving signals by the driver IC and transmitted to the TFT (Thin Film Transistor), enabling the display to show the desired image. To achieve a narrow chin, the width of the bottom bezel of the glass (the so-called display chin) needs to be shortened, but the bonding area between the IC and FPC is limited and cannot be infinitely small. To achieve a narrow chin design, the unused area of ​​the bottom bezel needs to be removed, following a common design approach... Figure 1 As shown, to achieve electronic performance, sufficient space must be left for circuit traces. To ensure mass production and yield, the IC bonding area and FPC bonding area have already been pushed to their limits. If the FPC bonding area were any narrower, the conductivity of the circuitry would be affected, and the display would not function properly. "Bonding" is a transliteration of the word "bonding," meaning connection. Therefore, a new method to shorten the bottom bezel is to move the FPC bonding area to the left or right of the IC bonding area, such as... Figure 1 As shown, there are three designs: one with the PIN protruding from the right, one with the PIN protruding from both sides in a concave shape, and one with the PIN protruding from the left; see the authorization announcement number CN 222028503U, entitled "A Utility Model Patent for a Narrow Bezel Display Panel" for details. Figures 2-4As shown, this eliminates the space required for the lower PIN bonding area, allowing for a narrower bottom bezel of the display screen. Simultaneously, it increases the width of the FPC bonding area, resulting in a higher number of explosive conductive particles in the bonded ACF (Anisotropic Conductive Film), ensuring the conductivity and strength of the connection between the FPC and the PIN. This also improves production yield and reduces the difficulty of bonding. However, there are limitations to this method in narrowing the glass bezel; there is still room for improvement in the bezel width.

[0004] At the same time, such as Figure 2 As shown, in order to achieve their different functions, existing display panels require connecting the functional components on the IC to the FPC. This structure makes it difficult to make the bottom bezel of the display panel narrower. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a display panel with a narrow bezel.

[0006] The technical solution is as follows: A display panel with a narrow bezel includes a panel body with a bottom bezel, an IC disposed within the bottom bezel, and an FPC electrically connected to the IC at one end; a recessed notch is provided in the horizontal outer edge of one end of the bottom bezel, and the bonding area between the FPC and the bottom bezel is located inside the horizontal edge of the notch; the IC is located on one side of the notch.

[0007] Preferably, after the FPC is folded along the lateral edge of the notch, its fold line is flush with or protrudes from the lateral outer edge of the lower frame, or the lateral outer edge protrudes from the fold line.

[0008] Preferably, the fold line is flush with the outer lateral edge of the lower frame.

[0009] Preferably, the notch is located inside the horizontal outer edge of the left end of the lower frame; the IC is located to the right of the notch.

[0010] Preferably, the notch is located inside the horizontal outer edge of the right end of the lower frame; the IC is located to the left of the notch.

[0011] Preferably, the bonding area has a plurality of solder joints electrically connected to one end of the FPC, and the IC has at least two regions, each region having a plurality of functional elements; a plurality of connecting lines electrically connected to the corresponding solder joints of the functional elements located in the region away from the bonding area pass through the region on the back side of the IC.

[0012] Technical Effect: A notch is provided at the left or right end of the lower frame of the panel body, recessed into the horizontal outer edge of the lower frame. One end of the FPC is bonded to the lower frame inside the horizontal edge of the notch. According to design requirements, after one end of the FPC is bonded, it needs to be folded along the horizontal edge of the notch so that the other end of the FPC is on the back of the panel body. The fold line of the folded FPC is flush with the horizontal outer edge of the lower frame, protrudes from the horizontal outer edge, or the horizontal outer edge protrudes from the fold line. In other words, there are three possibilities. However, when the FPC of existing similar products is folded, it is directly folded along the horizontal outer edge of the panel body, and the fold line will inevitably protrude from the horizontal outer edge. The width of the lower frame after folding will inevitably be wider than when folded along the horizontal edge of the notch. Therefore, the panel body of this utility model can have a narrower frame design, making the product using this panel more aesthetically pleasing. Attached Figure Description

[0020] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 3As shown, this utility model embodiment provides a display panel with a narrow bezel, which can be used in wearable devices such as smartwatches. It includes a panel body 1 with a lower bezel 101, an IC 2 disposed within the lower bezel, and an FPC 3 electrically connected to the IC at one end. A recessed notch 101a is provided in the lateral outer edge A of one end of the lower bezel 101, and the bonding area between the FPC and the lower bezel is located inside the lateral edge of the notch. The IC 2 is located on one side of the notch.

[0022] Obviously, the notch 101a can be located at the left or right end of the lower frame 101 and achieve the same effect. This embodiment will be described with the notch located at the left end of the lower frame as an example. That is, the notch 101a is located inside the horizontal outer edge of the left end of the lower frame 101; correspondingly, the IC 2 is located to the right of the notch.

[0023] In use, after FPC 3 is bonded, that is, after it is connected to the lower frame 101, FPC 3 needs to be folded along the horizontal edge of the notch 101a. The fold line is flush with the horizontal outer edge of the lower frame 101, protrudes from the horizontal outer edge, or the horizontal outer edge protrudes from the fold line. There are three scenarios. Specifically, in this embodiment, the fold line is flush with the horizontal outer edge of the lower frame 101. In practical applications, the folding area of ​​FPC 3 is generally 0.5–0.8 mm. If the lower frame 101 is wide enough, a notch 101a with a width of 0.5–0.8 mm can be cut, in which case the FPC fold line is basically flush with the horizontal outer edge. If the lower frame 101 is already very narrow, such a wide notch cannot be cut, and the FPC fold line will protrude from the horizontal outer edge, but the width of the lower frame is also narrower than that of the prior art. Of course, it is also possible that the width of the cut notch 101a is greater than the folding area space, in which case the fold line will not protrude from the horizontal outer edge A.

[0024] like Figure 6 As shown, it compares the width of the bottom bezel of the prior art display panel after the FPC is folded with the width of the bottom bezel 101 of the present invention display panel after the FPC 3 is folded. Obviously, the width of the bottom bezel 101 of the prior art FPC 3 after folding is smaller than that of the prior art.

[0025] Taking the use of a display panel in a smartwatch as an example, since the FPC 3 needs to be bent to the back of the panel body 1 after bonding, the watch case design needs to leave more than 0.8mm of installation space for the bending area. In order to make the bezel of the product case narrower, this space needs to be shortened. Therefore, the position of the IC 2 bonded to the bottom bezel 101 is moved closer to the left and right sides, and the other side is left for FPC 3 bonding. Correspondingly, the bottom bezel 101 needs to be chamfered. In this way, the FPC 3 bonding area shrinks inward, and the bending area (fold line) of FPC 3 also shrinks inward. The bezel of the product case can be designed to be narrower, which is more beautiful and fashionable.

[0026] like Figures 4-5 As shown, the bonding area has several solder points 4 electrically connected to one end of the FPC 3. The IC 2 has at least two regions, such as regions B and C, each containing several functional components 5. Several connecting lines electrically connected to the corresponding solder points 4 in the region far from the bonding area (region C in this case) pass through the region on the back side of the IC. This structure allows the functional components on the IC 2 to be completely connected to the FPC 3 without affecting the width of the lower border 101, i.e., it does not increase the width of the lower border.

[0027] The foregoing embodiments have described in detail the case where the notch 101a is set at the left end of the lower frame 101. Obviously, the notch 101a can also be set at the horizontal outer edge of the right end of the lower frame 101. The IC 2 is located to the left of the notch, and its effect is the same as that of the foregoing embodiments, so it will not be described again here.

[0028] In summary, according to the design requirements, after one end of the FPC 3 is bonded, it needs to be folded along the horizontal edge of the notch so that the other end of the FPC is located on the back of the panel body. The fold line of the folded FPC is flush with the horizontal outer edge A of the lower frame 101, or protrudes from the horizontal outer edge, or the horizontal outer edge protrudes from the fold line. In other words, there are three possibilities. However, when the FPC of existing similar products is folded, it is directly folded along the horizontal outer edge of the panel body. The fold line will inevitably protrude from the horizontal outer edge, and the width of the lower frame after folding will inevitably be wider than when folded along the horizontal edge of the notch. Therefore, the panel body of this utility model can have a narrower frame design, making the product using this panel more aesthetically pleasing.

[0029] In the above description, it should be noted that the terms "installation", "connection", "connection" and other related terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components; "set at" should be understood as "installed at" or "set at", including installation methods such as fixed installation and movable installation.

[0030] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Any equivalent structures made based on the description and drawings of this utility model, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
