Description

Technical Field

[0001] The present invention relates to the field of display technologies, and in particular, to a touch panel and a display device. Background Art

[0002] With the development of science and technology, the touch technology of display screens has also developed rapidly. Touch screens are widely used in electronic devices such as mobile phones, computers, e-books, and tablet computers, and have become an essential part of people's lives. With the emergence of various touch-enabled display devices, consumers' requirements for the aesthetics, performance, and other aspects of touch screens are getting higher and higher. The capacitive touch screen is a touch structure widely used in display devices. The capacitive touch screen with an external structure is mainly of the GF (Glass-Film) structure or the GFF (Glass-Film-Film) structure, that is, the structure of a glass cover plate - thin film electrode or the structure of a glass cover plate - thin film electrode - thin film electrode, and the thin film electrode needs to be bonded to a flexible printed circuit (FPC) located at one end of the touch panel to achieve electrical connection with other electronic components of the display device.

[0003] In the prior art, the middle part of the touch panel is the visible area. The edges of the visible area are connected by opaque metal leads to bond the thin film electrodes to the flexible printed circuit located at the top or bottom of the touch panel, so as to achieve the electrical connection between the flexible printed circuit and the thin film electrodes. And for the overall aesthetic effect of the display device, a black light-shielding layer needs to be printed at the position corresponding to the flexible printed circuit on the top or bottom of the glass cover plate to cover the metal leads and the flexible printed circuit. Since the overlapping part of the metal leads and the flexible printed circuit has a large size in the length direction of the touch panel, the size of the flexible printed circuit is increased, resulting in a large coverage area of the flexible printed circuit in the length direction of the touch panel, correspondingly increasing the size of the black light-shielding layer, thereby affecting the size of the visible area and reducing the screen-to-body ratio of the display device, and greatly reducing the user experience. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a touch panel and a display device to solve the problems in the prior art that the top or bottom border of the touch panel is relatively wide, the visible area is small, the screen-to-body ratio is low, and the user experience is poor.

[0005] To solve the above technical problems, the present invention provides a touch panel, which includes a flexible circuit board, a first electrode, and a conductive lead. The flexible circuit board is located at one end of the touch panel in the length direction and is electrically connected to the main board of the display device. The flexible circuit board is provided with a first bonding point, and the first bonding point includes at least one first long side, and the first long side extends along the width direction of the touch panel. The first electrode is electrically connected to the first bonding point through the conductive lead and thus electrically connected to the flexible circuit board. In this way, the first bonding point includes at least a first long side, and the first long side extends along the width direction of the touch panel, avoiding the first long side of the first bonding point being arranged along the length direction of the touch panel, reducing the size of the flexible circuit board in the length direction of the touch panel. The flexible circuit board overlaps the conductive lead through the first bonding point, so the coverage area of the flexible circuit board in the length direction of the touch panel is correspondingly reduced, the size of the black light-shielding layer is reduced, thereby increasing the size of the visible area and improving the screen-to-body ratio of the display device, greatly improving the user experience.

[0006] Further, one end of the conductive lead bonded to the first bonding point has the same shape as the first bonding point. In this way, the overlapping area between the conductive lead and the first bonding point can be guaranteed, thereby improving the electrical connection performance between the two.

[0007] Further, the shape of the first bonding point is a rectangle, a triangle, a trapezoid, or a hexagon. In this way, it can be ensured that the first bonding point includes at least one first long side, and the first long side extends along the width direction of the touch panel, avoiding the first long side of the first bonding point being arranged along the length direction of the touch panel, reducing the size of the flexible circuit board in the length direction of the touch panel.

[0008] Further, the area of the first bonding point is greater than or equal to 0.045 square millimeters and less than or equal to 0.75 square millimeters. When the area of the first bonding point is less than 0.045 square millimeters, the bonding area between the conductive lead and the first bonding point is too small, and the bonding deviation is likely to cause poor bonding between the two, resulting in a low yield; when the area of the first bonding point is greater than 0.75 square millimeters, to ensure that the flexible circuit board can accommodate the same number of first bonding points to bond the conductive leads, it is necessary to have a wide enough area in the width direction of the touch panel, which is not conducive to the layout of the touch keys and increases the manufacturing cost of the flexible circuit board.

[0009] Further, the panel of the first bonding point is greater than or equal to 0.025 square millimeters and less than or equal to 0.050 square millimeters. When the area of the first bonding point is less than or equal to 0.025 square millimeters, it is likely to result in too little bonding area between the conductive lead and the first bonding point, and the bonding deviation is likely to cause poor bonding between the two; when the panel of the first bonding point is greater than or equal to 0.050 square millimeters, it is likely to cause the flexible circuit board to occupy a relatively large area in the width direction of the touch panel, which is not conducive to the layout of touch keys and increases the manufacturing cost.

[0010] Further, the number of the first bonding points is multiple, and the first bonding points are arranged along the width direction of the touch panel. In this way, the size of the flexible circuit board in the length direction of the touch panel is reduced. The flexible circuit board overlaps the conductive lead through the first bonding point, correspondingly reducing the coverage area of the flexible circuit board in the length direction of the touch panel.

[0011] Further, the flexible circuit board is further provided with a plurality of second bonding points. The second bonding point includes at least one second long side, the second long side extends along the length direction of the touch panel, and the second bonding points are arranged along the width direction of the touch panel. In this way, the second bonding points are arranged parallel to the length direction of the touch panel, thereby reducing the size of the flexible circuit board in the width direction of the touch panel.

[0012] Further, the number of the first electrodes is multiple. Some of the first electrodes are electrically connected to the first bonding points through the conductive leads, and some of the first electrodes are electrically connected to the second bonding points through the conductive leads. In this way, the coverage area of the flexible circuit board in both the length direction and the width direction of the touch panel is reduced at the same time, correspondingly reducing the size of the black light-shielding layer used to block the flexible circuit board, thereby increasing the size of the visible area, improving the screen-to-body ratio of the display device, and greatly improving the user experience.

[0013] Further, the touch panel further includes a second electrode. Both the first electrode and the second electrode are electrically connected to the flexible circuit board through the first bonding point. In this way, the first bonding points are arranged parallel to the width direction of the touch panel, reducing the size of the flexible circuit board in the length direction of the touch panel.

[0014] Further, the touch panel further includes a second electrode. The first electrode is electrically connected to the flexible circuit board through the first bonding point, and the second electrode is electrically connected to the flexible circuit board through the second bonding point. In this way, the coverage area of the flexible circuit board in both the length direction and the width direction of the touch panel is reduced at the same time, correspondingly reducing the size of the black light-shielding layer used to block the flexible circuit board, thereby increasing the size of the visible area, improving the screen-to-body ratio of the display device, and greatly improving the user experience.

[0015] Further, the touch panel further includes a second electrode. The first electrode is electrically connected to the flexible circuit board through the second bonding point, and the second electrode is electrically connected to the flexible circuit board through the first bonding point. In this way, the coverage area of the flexible circuit board in the length direction and the width direction of the touch panel is reduced, and correspondingly, the size of the black light-shielding layer for shielding the flexible circuit board is reduced, thereby increasing the size of the visible area and improving the screen-to-body ratio of the display device, greatly improving the user experience.

[0016] The present invention also provides a display device, which includes a display panel and the touch panel according to any one of the above. The display panel and the touch panel are stacked, and the display panel outputs an image and is displayed through the transparent area of the touch panel.

[0017] The beneficial effects of the present invention are as follows: The first bonding point includes at least one first long side, and the first long side extends along the width direction of the touch panel, avoiding the first bonding point arranging the first long side along the length direction of the touch panel, reducing the size of the flexible circuit board in the length direction of the touch panel. The flexible circuit board is lapped with a conductive lead through the first bonding point, so correspondingly, the coverage area of the flexible circuit board in the length direction of the touch panel is reduced, the size of the black light-shielding layer is reduced, thereby increasing the size of the visible area and improving the screen-to-body ratio of the display device, greatly improving the user experience.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figure 1 and Figure 2 , the touch panel provided in the first embodiment of the present invention includes a flexible circuit board 20, a first electrode 12, and a conductive lead 30. In a preferred implementation manner, the touch panel is rectangular as a whole, and the touch panel includes a length direction and a width direction that are perpendicular to each other. In this embodiment, the first electrode 12 is a conductive film formed of a transparent conductive material. In a preferred implementation manner, the first electrode 12 is a patterned indium tin oxide (ITO) film. Further, the number of the first electrodes 12 is multiple, and the first electrodes 12 are arranged in an array along the width direction of the touch panel to form a touch panel with a GF structure.

[0027] The flexible circuit board 20 is located at one end of the length direction of the touch panel and is electrically connected to the main board of the display device. Specifically, the flexible circuit board 20 is located at the top or bottom of the touch panel. The flexible circuit board 20 has the characteristics of being bendable and having good electrical conductivity. One end of the flexible circuit board 20 is electrically connected to the touch panel, and the other end is electrically connected to the main board or electrically connected to the display panel and then electrically connected to the main board through the display panel. After the touch panel receives the touch of a user's finger, it receives a touch signal with touch information, and then transmits the touch signal to the main board in the form of an electrical signal for analysis and processing.

[0028] The flexible circuit board 20 is provided with a first bonding point 22. The first bonding point 22 includes at least one first long side 222, and the first long side 222 extends along the width direction of the touch panel. Specifically, the first bonding point 22 further includes a pair of first short sides 224. The pair of first short sides 224 are respectively connected to both ends of the pair of first long sides 222 to form a closed figure. In one implementation manner, the first bonding point 22 is rectangular. Further, the first bonding point 22 is arranged parallel to the width direction of the touch panel, thereby reducing the size of the flexible circuit board 20 in the length direction of the touch panel.

[0029] The first electrode 12 is electrically connected to the first bonding point 22 through a conductive lead 30, and thus is electrically connected to the flexible circuit board 20. Further, the conductive lead 30 is an opaque metal lead. In a preferred embodiment, the conductive lead 30 is a silver paste wire, that is, a silver wire formed by chemically etching or laser etching a silver paste layer. The silver paste wire has good electrical conductivity, reduces the overall impedance of the touch panel, and improves the touch effect. Further, the silver paste wire is electrically connected to the first bonding point 22, so that the first electrode 12 is electrically connected to the flexible circuit board 20. In a preferred embodiment, the first bonding point 22 is a metal sheet protruding from the flexible circuit board 20 and has good electrical conductivity characteristics. The combination of the silver paste wire and the first bonding point 22 has a good wire bonding effect and is easy to bond.

[0030] The first bonding point 22 includes at least one first long side 222, and the first long side 222 extends along the width direction of the touch panel, avoiding setting the first long side 222 of the first bonding point 22 along the length direction of the touch panel, reducing the size of the flexible circuit board 20 in the length direction of the touch panel. The flexible circuit board 20 overlaps the conductive lead 30 through the first bonding point 22, so the coverage area of the flexible circuit board 20 in the length direction of the touch panel is correspondingly reduced, the size of the black light-shielding layer is reduced, thereby increasing the size of the visible area and improving the screen-to-body ratio of the display device, greatly improving the user experience.

[0031] In this embodiment, the end of the conductive lead 30 bonded to the first bonding point 22 has the same shape as the first bonding point 22. This can ensure the overlapping area between the conductive lead 30 and the first bonding point 22, thereby improving the electrical connection performance between the two.

[0032] In this embodiment, the shape of the first bonding point 22 is rectangular, triangular, trapezoidal or hexagonal. This can ensure that the first bonding point 22 includes at least one first long side 222, and the first long side 222 extends along the width direction of the touch panel, avoiding setting the first long side 222 of the first bonding point 22 along the length direction of the touch panel, reducing the size of the flexible circuit board 20 in the length direction.

[0033] In this embodiment, the area of the first bonding point 22 is greater than or equal to 0.045 square millimeters and less than or equal to 0.75 square millimeters. When the area of the first bonding point 22 is less than 0.045 square millimeters, the bonding area between the conductive lead 30 and the first bonding point 22 is too small, and the bonding deviation is likely to cause poor bonding between the two, resulting in a low yield; when the area of the first bonding point 22 is greater than 0.75 square millimeters, to ensure that the flexible circuit board 20 can accommodate the same number of first bonding points 22 to bond the conductive lead 30, it is necessary to have a sufficiently wide area in the width direction of the touch panel, which is not conducive to the layout of the touch buttons and increases the manufacturing cost of the flexible circuit board 30.

[0034] In this embodiment, the panel area of the first bonding point 22 is greater than or equal to 0.025 square millimeters and less than or equal to 0.050 square millimeters. When the area of the first bonding point 22 is less than or equal to 0.025 square millimeters, it is likely to result in too little bonding area between the conductive lead 30 and the first bonding point 22, and bonding deviation is likely to cause poor bonding between the two. When the panel area of the first bonding point 22 is greater than or equal to 0.050 square millimeters, it is likely to cause the flexible circuit board 20 to occupy a relatively large area in the width direction of the touch panel, which is not conducive to the layout of touch keys and increases the manufacturing cost.

[0035] In this embodiment, the number of the first bonding points 22 is multiple, and the first bonding points 22 are arranged along the width direction of the touch panel. Specifically, each first bonding point 22 is correspondingly connected to a first electrode 12 through a conductive lead 30, so that each first electrode 12 is electrically connected to the main board of the display device through an independent channel. In a preferred embodiment, the first bonding points 22 are arranged in a straight line along the width direction of the touch panel, which is convenient for the routing design of the internal channels of the flexible circuit board 20, so as to reduce the size of the flexible circuit board 20 in the length direction of the touch panel.

[0036] Please refer to Figure 3 , the difference between the touch panel provided in the second embodiment of the present invention and the first embodiment lies in that the flexible circuit board 20 is further provided with a plurality of second bonding points 24. The second bonding points 24 include at least one second long side 242, and the second long side 242 extends along the length direction of the touch panel. The second bonding points 24 are arranged along the width direction of the touch panel. Specifically, the second bonding points 24 further include a pair of second short sides 244, and the pair of second short sides 244 are respectively connected to both ends of a pair of second long sides 242 to form a closed figure. In one embodiment, the second bonding points 24 are rectangular. Further, the second bonding points 24 are arranged parallel to the length direction of the touch panel, thereby reducing the size of the flexible circuit board 20 in the width direction of the touch panel. In this embodiment, the first bonding points 22 and the second bonding points 24 are jointly arranged along the width direction of the touch panel. In a preferred embodiment, the first bonding points 22 and the second bonding points 24 are arranged on the same straight line along the width direction of the touch panel, which is convenient for the routing design of the internal channels of the flexible circuit board 20, so as to reduce the size of the flexible circuit board 20 in the length direction of the touch panel. Further, the first bonding points 22 and the second bonding points 24 can be arranged in an alternating manner, or a plurality of first bonding points 22 can be continuously arranged and then a plurality of second bonding points 24 can be continuously arranged. The first bonding points 22 reduce the size of the flexible circuit board 20 in the length direction of the touch panel, the second bonding points 24 reduce the size of the flexible circuit board 20 in the width direction of the touch panel, and the mixed arrangement of the first bonding points 22 and the second bonding points 24 reduces the size of the flexible circuit board 20 in both the length direction and the width direction of the touch panel.

[0037] In this embodiment, the number of the first electrodes 12 is multiple. Some of the first electrodes 12 are electrically connected to the first bonding points 22 through the conductive leads 30, and some of the first electrodes 12 are electrically connected to the second bonding points 24 through the conductive leads 30. Further, the electrical connection between the first electrodes 12 and the first bonding points 22 reduces the size of the overlapping portion of the conductive leads 30 and the flexible circuit board 20 in the length direction of the touch panel, thereby reducing the area covered by the flexible circuit board 20 in the length direction of the touch panel; the electrical connection between the first electrodes 12 and the second bonding points 24 reduces the size of the overlapping portion of the flexible circuit board 20 in the width direction of the touch panel, thereby reducing the area covered by the flexible circuit board 20 in the width direction of the touch panel. The electrical connection of the first electrodes 12 to both the first bonding points 22 and the second bonding points 24 reduces the area covered by the flexible circuit board 20 in both the length direction and the width direction of the touch panel, correspondingly reducing the size of the black light-shielding layer for shielding the flexible circuit board 20, thereby increasing the size of the visible area and improving the screen-to-body ratio of the display device, and greatly improving the user experience.

[0038] In a preferred embodiment, the number of the first bonding points 22 is the same as that of the second bonding points 24, so that the number of the conductive leads 30 electrically connecting the first bonding points 22 and the first electrodes 12 is the same as the number of the conductive leads 30 electrically connecting the second bonding points 24 and the first electrodes 12, so as to balance and adjust the sizes of the flexible circuit board 20 in the length direction and the width direction of the touch panel.

[0039] Please refer to Figure 4 , the difference between the touch panel provided in the third embodiment of the present invention and the first embodiment lies in that the touch panel further includes a second electrode 14, and the first electrode 12 and the second electrode 14 are stacked to form a capacitive structure. Specifically, the first electrode 12 is a driving electrode, and the second electrode 24 is a sensing electrode. In this embodiment, the second electrode 14 is a conductive film formed of a transparent conductive material. In a preferred embodiment, the second electrode 24 is a patterned indium tin oxide (ITO) film. Further, the number of the second electrodes 14 is multiple, and the second electrodes 14 are arranged in an array along the length direction of the touch panel. The first electrode 12 and the second electrode 14 are stacked to form a capacitive touch panel with a GFF structure. The capacitive touch panel with a GFF structure has high touch accuracy, can achieve multi-touch, and has low production cost and simple production process.

[0040] Further, both the first electrode 12 and the second electrode 14 are electrically connected to the flexible circuit board 20 through the first bonding point 22. The first long side 222 of the first bonding point 22 extends along the width direction of the touch panel, that is, the first bonding point 22 is arranged parallel to the width direction of the touch panel, reducing the size of the flexible circuit board 20 in the length direction of the touch panel. The flexible circuit board 20 overlaps the conductive lead 30 through the first bonding point 22, correspondingly reducing the covering area of the flexible circuit board 20 in the length direction of the touch panel, reducing the size of the black light-shielding layer, thereby increasing the size of the visible area, improving the screen-to-body ratio of the display device, and greatly improving the user experience.

[0041] Please refer to Figure 5 , the difference between the touch panel provided in the fourth embodiment of the present invention and the third embodiment lies in that the first electrode 12 is electrically connected to the flexible circuit board 20 through the first bonding point 22, and the second electrode 14 is electrically connected to the flexible circuit board 20 through the second bonding point 24. The electrical connection of the first electrode 12 to the first bonding point 22 reduces the size of the overlapping portion of the conductive lead 30 and the flexible circuit board 20 in the length direction of the touch panel, thereby reducing the covering area of the flexible circuit board 20 in the length direction of the touch panel; the electrical connection of the second electrode 14 to the second bonding point 24 reduces the size of the overlapping portion of the flexible circuit board 20 in the width direction of the touch panel, thereby reducing the covering area of the flexible circuit board 20 in the width direction of the touch panel. The electrical connection of the first electrode 12 and the second electrode 14 to the first bonding point 22 and the second bonding point 24 respectively reduces the covering areas of the flexible circuit board 20 in the length direction and the width direction of the touch panel, correspondingly reducing the size of the black light-shielding layer for shielding the flexible circuit board 20, thereby increasing the size of the visible area, improving the screen-to-body ratio of the display device, and greatly improving the user experience.

[0042] Please refer to Figure 6, the difference between the touch panel provided in the fourth embodiment of the present invention and the third embodiment lies in that the first electrode 12 is electrically connected to the flexible circuit board 20 through the second bonding point 24, and the second electrode 14 is electrically connected to the flexible circuit board 20 through the first bonding point 22. The electrical connection of the second electrode 14 to the first bonding point 22 reduces the size of the overlapping portion of the conductive lead 30 and the flexible circuit board 20 in the length direction of the touch panel, thereby reducing the area covered by the flexible circuit board 20 in the length direction of the touch panel; the electrical connection of the first electrode 12 to the second bonding point 24 reduces the size of the overlapping portion of the flexible circuit board 20 in the touch panel in the width direction, thereby reducing the area covered by the flexible circuit board 20 in the width direction of the touch panel. The electrical connection of the first electrode 12 and the second electrode 14 to the second bonding point 24 and the first bonding point 22 respectively reduces the area covered by the flexible circuit board 20 in the length and width directions of the touch panel, correspondingly reducing the size of the black light-shielding layer for shielding the flexible circuit board 20, thereby increasing the size of the visible area and improving the screen-to-body ratio of the display device, greatly improving the user experience.

[0043] The touch panel provided in the embodiment of the present invention further includes a cover plate. The cover plate, the first electrode 12, and the second electrode 24 are stacked. A light-shielding layer is printed on the edge of the cover plate to shield the conductive lead 30 and the flexible circuit board 20. Specifically, the cover plate is made of a transparent material such as glass or plastic. The cover plate is used to protect the touch panel and the display panel while contacting the user's finger for touch operation. The light-shielding layer on the edge of the cover plate shields the top or bottom of the touch panel, correspondingly shielding the opaque conductive lead 30 and the flexible circuit board 20, and beautifying the appearance of the display device.

[0044] The embodiment of the present invention further provides a display device, including a display panel and the touch panel described above. The display panel and the touch panel are stacked, and the display panel outputs an image and is displayed through the transparent area of the touch panel. In this embodiment, the display device includes a mobile phone, a tablet computer, a television, etc.

[0045] Furthermore, the display device further includes a system main board, a housing, and a battery. The system main board is electrically connected to the touch panel and the display panel and controls the operation of the touch panel and the display panel. The battery is used to supply power to the main board. The housing houses the main board, the battery, the touch panel, and the display panel, playing a role in protecting the internal components of the display device and beautifying the appearance.

[0046] The first bonding point 22 includes at least one first long side 222 which extends along the width direction of the touch panel, avoiding arranging the first long side 222 of the first bonding point 22 along the length direction of the touch panel, reducing the size of the flexible circuit board 20 in the length direction of the touch panel. The flexible circuit board 20 overlaps the conductive lead 30 through the first bonding point 22. Therefore, the covering area of the flexible circuit board 20 in the length direction of the touch panel is correspondingly reduced, the size of the black light-shielding layer is reduced, thereby increasing the size of the visible area, improving the screen-to-body ratio of the display device, and greatly improving the user experience.

[0047] The above-disclosed are only several preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby.
