Among them, the capacitive touch panel has become the mainstream technical solution for modern touch display screens with its high sensitivity and stability. The typical structure uses a metal mesh electrode layer as the core sensing unit, and realizes the accurate capture and transmission of touch signals by embedding the micron-level precision-etched electrode layer inside the display panel.
[0003] In the existing capacitive touch panel, the internal transmitting electrode (Tx) and receiving electrode (Rx) usually form an integrated metal mesh structure by using the same-layer coplanar wiring design. However, a micro short-circuit path is extremely easy to form between adjacent electrodes, resulting in abnormal touch signals. Moreover, the parasitic capacitance in the electrode coupling area increases significantly, causing the touch capacitance reference value to deviate from the design threshold. These problems directly lead to a decrease in touch sensitivity and a deterioration of the signal-to-noise ratio, seriously affecting touch accuracy and user experience.

[0038] The embodiments of the present application are described in detail below. The examples of the embodiments of the present application are shown in the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. All the technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present application belongs. The terms used in the description of the present application are only for the purpose of describing specific implementation manners and are not intended to limit the present application. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.
[0039] In the embodiments of the present application, "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist. Unless otherwise defined, the technical terms or scientific data used in the present application should have the ordinary meaning understood by those with ordinary skills in the technical field to which the present application belongs. In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.
[0040] In order to solve the technical problems existing in the background art, in the prior art, it is usually adopted to insulate and isolate the transmitting electrode 3 and the receiving electrode 4 by setting a small and single-break form at the junction of the transmitting electrode 3 and the receiving electrode 4, as Figure 5 shown. However, during the manufacturing process of the touch panel, due to factors such as etching process defects, photoresist residues, or metal migration, metal residues 0 of different sizes will be formed at the junction of the transmitting electrode 3 and the receiving electrode 4, or at the junction of the transmitting electrode 3 / receiving electrode 4 and the virtual electrode 5, as Figures 1 to 4 shown. These metal residues 0 have a high probability of covering the break 0', resulting in the formation of an additional conduction circuit between different electrodes, thereby causing the touch panel to short-circuit or the capacitance value of the formed touch capacitor to be too large, thus reducing the touch accuracy.
[0041] However, during the production process of the touch panel, it is impossible to completely avoid metal residues. It can only avoid the short-circuit of the touch panel or the situation where the capacitance value of the touch capacitor is too large by reducing the frequency of the complete coverage of the metal residues at the junctions between different electrodes. Currently, due to the metal residues covering the single break, the yield loss rate is about 0.2%, so it will partially leak to the MOD (Module, functional module), thereby increasing the consumable cost and affecting the normal operation of the production line.
[0042] Based on this, the inventor found that multiple breaks can be serially arranged at the junctions between different electrodes to form a multi-break line gate to avoid the above situation. When the metal residues cover one or more of the breaks, the remaining breaks can still play the role of isolating the transmitting electrode and the receiving electrode, or isolating the transmitting electrode / receiving electrode and the virtual electrode, and play a multi-layer shielding role for the problems of short-circuit of the touch panel and too large capacitance value caused by the metal residues covering the breaks, thereby reducing the cost and greatly improving the yield compared with the prior art.
[0043] A detailed description will now be given of an organic light-emitting panel provided by an embodiment of the present application.
[0044] An embodiment of the present application provides an organic light-emitting display panel, including a touch layer. Figure 8 The emission electrode 3, the receiving electrode 4, and the virtual electrode 5 provided on the touch layer are shown. In an embodiment of the present application, the touch layer includes a metal mesh provided thereon. The metal mesh includes metal mesh units that are electrically connected to each other, and each metal mesh unit is polygonal. A unit edge 1 is formed between adjacent vertices of each metal mesh unit. Among them, the unit edge 1 includes a set of predetermined unit edges at a plurality of predetermined positions of the metal mesh. Each predetermined unit edge 11 in the set of predetermined unit edges is provided with at least one break 2, forming a set of breaks. The set of predetermined unit edges includes a non-empty subset of predetermined unit edges, and each predetermined unit edge 11 in the non-empty subset of predetermined unit edges is provided with at least two breaks 2. Thus:
[0045] As Figure 8 shown, the set of breaks can divide the metal mesh into the electrically isolated emission electrode 3 and the receiving electrode 4.
[0046] Or, the set of breaks can divide the metal mesh into the electrically isolated emission electrode 3, the receiving electrode 4, and the virtual electrode 5.
[0047] In some embodiments, as Figure 7 shown, the metal mesh unit is a quadrilateral, and each metal mesh unit is electrically connected to each other. Figure 7 The metal meshes arranged up and down in are the emission electrode 3 and the receiving electrode 4 composed of metal mesh units of different colors. In some embodiments, a plurality of metal mesh units are integrally formed. Therefore, physical insulation needs to be performed on the metal mesh units at the junction of the emission electrode 3 and the receiving electrode 4 to form the electrically isolated emission electrode 3 and the receiving electrode 4, or to form the electrically isolated emission electrode 3, the receiving electrode 4, and the virtual electrode 5.
[0048] According to the above embodiment, the metal mesh units at the predetermined positions further include a predetermined unit edge 11. In some embodiments, the predetermined unit edge 11 is the unit edge 1 on the metal mesh unit at the junction of the emission electrode 3 and the receiving electrode 4, or the unit edge 1 on the metal mesh unit at the junction of the emission electrode 3, the receiving electrode 4, and the virtual electrode 5.
[0049] In some embodiments, when the organic light-emitting panel is not provided with the virtual electrode 5, the predetermined position is the junction between the emission electrode 3 and the receiving electrode 4. At this time, only by providing a break 2 on the predetermined unit edge 11 at the junction of the emission electrode 3 and the receiving electrode 4, the emission electrode 3 and the receiving electrode 4 can be insulated and isolated, thereby realizing the touch function.
[0050] In some other embodiments, when the virtual electrode 5 is provided on the organic light-emitting panel, the predetermined position is the junction between the emitting electrode 3, the receiving electrode 4 and the virtual electrode 5 respectively. At this time, it is necessary to provide a break 2 at the junction of the emitting electrode 3 and the receiving electrode 4, and on the predetermined unit side 11 at the junction of the emitting electrode 3, the receiving electrode 4 and the virtual electrode 5, that is, the emitting electrode 3 and the receiving electrode 4, as well as the emitting electrode 3, the receiving electrode 4 and the virtual electrode 5 can be insulated from each other, so as to realize the touch function.
[0051] It should be noted that the virtual electrode 5 (Dummy) is usually used to detect the capacitance change of the touch point on the capacitive touch screen. When the number of electrodes of the touch panel is limited by the hardware cost and the screen transmittance, the virtual electrode 5 can generate more virtual monitoring points through algorithms, thus greatly improving the touch accuracy and the screen resolution. In the embodiments of the present application, the virtual electrode 5 is Figure 8 where the D area is located. The virtual electrode 5, the emitting electrode 3 and the receiving electrode 4 are all composed of a plurality of metal grid units. Therefore, it is also necessary to insulate the virtual electrode 5 from the receiving electrode 3 and the emitting electrode 4 to realize the touch function.
[0052] In some embodiments, as Figure 7 shown, at least one break 2 is provided on each predetermined unit side 11, so as to solve the insulation problem of adjacent electrode regions. However, when the generated metal residue covers the break 2, it will also cause the adjacent electrode regions to be reconnected and conduct, resulting in problems such as short circuit of the touch panel.
[0053] In some other embodiments, at least two breaks 2 are provided on each predetermined unit side 11. Such a setting further reduces the possibility that the metal residue completely covers the break 2 to cause a short circuit of the touch panel, thereby improving the touch accuracy of the touch panel.
[0054] In addition, in some other embodiments, at least two breaks 2 are provided on some of the predetermined unit sides 11. Such a setting can ensure that even when the metal residue covers some of the breaks, there are other breaks to separate different electrode regions.
[0055] In the embodiments of the present application, the number of breaks provided on each predetermined unit side 11 may be the same or different. The embodiments of the present application do not limit the number of breaks provided on each predetermined unit side, as long as it can shield the problems such as short circuit of the touch panel caused by metal residue. Generally speaking, the more the number of breaks, the lower the possibility that the metal residue can cover all the breaks, and the less likely the problems of short circuit of the touch panel and the excessive capacitance value of the generated touch capacitance will occur.
[0056] It should be noted that in a touch panel, when metal residue covers the break 2, an additional conduction circuit will be formed between the emitting electrode 3 and the receiving electrode 4, causing local or global short circuits in the touch panel. Theoretically, the more the number of breaks 2, even if some breaks are covered by metal residue, there may be other breaks that play an insulating role, reducing the possibility that the metal residue can completely cover the breaks.
[0057] In some embodiments, the touch layer provided in the organic light-emitting display panel of the present application is formed on a thin film encapsulation, which is commonly found in electronic devices such as flexible OLEDs. It can simplify the structure, reduce the thickness, and improve the system reliability. The organic light-emitting material in the organic light-emitting display panel is extremely vulnerable to water and oxygen erosion, while the thin film encapsulation can form a protective layer through the stacking of multiple inorganic / organic materials to protect the organic light-emitting material. In the organic light-emitting display panel, the touch layer is usually directly deposited on the outermost layer of the thin film encapsulation, that is, the touch layer is fabricated on the surface after the encapsulation is completed. In the embodiments of the present application, the organic light-emitting display device using the thin film encapsulation has a thinner structure, a higher light transmittance, and better flexibility, greatly improving the performance of the organic light-emitting display panel.
[0058] In some embodiments, at least two breaks 2 provided on the predetermined unit side 11 are designed by the series connection method to form a double-break / multi-break line gate at the junction between adjacent electrode regions, thereby providing a double-layer / multi-layer shielding effect for problems such as short circuits caused by metal residue covering the break 2.
[0059] In some embodiments, the distance between any two of the at least two breaks 2 provided on the predetermined single side 11 is set as large as possible. The large-sized breaks make the possibility that the metal residue completely covers the breaks greatly reduced when large-sized metal residue and small-sized metal residue fall on the break 2, improving the insulation between adjacent electrode regions.
[0060] In a specific embodiment, as Figure 8 shown, the predetermined unit side 11 is entirely deleted, that is, the distance between the two breaks 2 provided on the predetermined unit side 11 and farthest apart is equal to the length of the predetermined unit side 11. Such a setting can also achieve the purpose of reducing the possibility that metal residue affects the touch accuracy, and can have a good shielding effect on metal residue with a length not exceeding the length of the predetermined unit side 11, avoiding the possibility that the vast majority of metal residue covers the breaks, thereby improving the touch accuracy.
[0061] In some embodiments, a touch capacitance can be formed at at least two breaks 2 that separate the transmitting electrode 3 and the receiving electrode 4. Among them, the touch capacitance is generally used to detect capacitance changes to identify the touch position and action. When the touch panel is touched, the capacitance value between the transmitting electrode 3 and the receiving electrode 4 will change, and the touch controller then determines the position of the touch point by measuring this change.
[0062] In the embodiments of the present application, the essence of the touch capacitance is the electric field coupling between the transmitting electrode 3 and the receiving electrode 4. When a driving signal is applied to the transmitting electrode 3, an electric field will be generated around it, and part of the electric field will be coupled to the adjacent receiving electrode 4 to form an initial capacitance Cm. When a finger approaches or touches the screen, the finger, as a conductor, absorbs part of the electric field, resulting in a decrease in the coupling capacitance between the transmitting electrode 3 and the receiving electrode 4. When metal residue covers the break, causing the transmitting electrode 3 and the receiving electrode 4 to conduct again, it will cause an increase in the capacitance value of the coupling capacitance, thereby reducing the touch accuracy of the touch panel. Therefore, an organic light-emitting display panel provided in the present application reduces the coverage rate of metal residue by setting at least two breaks 2 on the predetermined unit edge 11, thereby improving the touch accuracy of the touch panel and thus improving the performance of the panel.
[0063] It should be noted that for the influence of the increase in capacitance value, according to the following formula:
[0064] C = εS / 4πkd
[0065] Where C is the touch capacitance between the transmitting electrode and the receiving electrode, ε is the dielectric constant, S is the area of the capacitor plates facing each other, d is the distance between the capacitor plates, and K is the electrostatic constant.
[0066] The larger the area S of the capacitor plates composed of the transmitting electrode 3 and the receiving electrode 4, the larger the electric field interaction area with other conductors (such as the ground plane, adjacent lines). Therefore, it will cause an increase in the parasitic capacitance between the transmitting electrode 3 and the receiving electrode 4. Therefore, to reduce the touch capacitance and improve the touch accuracy, by setting multiple breaks 2 at the junction of the transmitting electrode 3 and the receiving electrode 4, the area of the capacitor plates is reduced to a certain extent, thereby reducing the electric field interaction area with other conductors, reducing the touch capacitance, and improving the touch accuracy.
[0067] As Figure 8 shown, this figure is the top view of the touch layer after setting double breaks by the series method in the above embodiment. In summary, the organic light-emitting display panel provided in this embodiment increases the number of breaks, reduces the possibility of metal residue covering the breaks, and reduces the area of the capacitor plates, thereby improving the touch accuracy.
[0068] It should be understood that although in the accompanying drawings of the present application, a series of double breaks are additionally provided on the single break beside the predetermined unit, those skilled in the art should know that setting only two breaks beside the predetermined unit can also achieve the technical effects that the present application can achieve. Metal residues that completely cover all the breaks can be detected, so the present application does not analyze metal residues that completely cover all the breaks.
[0069] The second aspect of the present application provides an information terminal, including an organic light-emitting display panel provided in the first aspect of the present application, and the touch screen performance of this information terminal is greatly improved compared with the prior art.
[0070] Example 1
[0071] In a specific embodiment of the present application, an embodiment is described in detail in which the virtual electrode 5 is not provided, and a series of double breaks are provided on the single break of the predetermined unit side 11.
[0072] Two breaks 2 are provided at both ends of the predetermined unit side 11 between the emission electrode 3 and the reception electrode 4 by the series method. At this time, the emission electrode 3 and the reception electrode 4 are isolated and insulated at both ends of the predetermined unit side 11, forming a double barrier effect. Even if there are large-size metal residues and / or small-size metal residues at the emission electrode 3 and the reception electrode 4 in the touch panel, it will not cause an additional conductive path to be formed in the touch panel, thereby changing the electric field distribution between the emission electrode 3 and the reception electrode, resulting in a short circuit between the emission electrode 3 and the reception electrode, and an abnormal increase in the touch capacitance value formed between the emission electrode 3 and the reception electrode, thus affecting the touch function.
[0073] In a specific embodiment, the virtual electrode 5 is not provided on the touch layer, and series double breaks are provided on some of the predetermined unit sides 11, and single breaks are maintained on other predetermined unit sides 11 to achieve the purpose of insulating and isolating adjacent electrode regions. Series double breaks are provided in areas where the probability of metal residue being left is high, and single breaks are provided in other areas, which can also reduce the possibility of being completely covered by metal residues. Moreover, setting series double breaks on some of the predetermined unit sides 11 also simplifies the process, thereby reducing costs.
[0074] In another specific embodiment, the virtual electrode 5 is not provided on the touch layer, and series double breaks are provided on all the predetermined unit sides 11 to achieve the purpose of insulating and isolating adjacent electrode regions. This setting greatly reduces the possibility of panel short circuit caused by metal residue coverage compared with the above specific embodiment, thereby improving touch stability.
[0075] Example 2
[0076] In a specific embodiment of the present application, an example is described in detail in which a virtual electrode 5 is provided and a series double break is provided at a single break of a predetermined unit side 11.
[0077] As Figure 7 shown, two breaks 2 are provided at both ends of the predetermined unit side 11 by using the series method at the junction between the transmitting electrode 3, the receiving electrode 4, and the virtual electrode 5. At this time, the transmitting electrode 3, the receiving electrode 4, and the virtual electrode 5 are isolated and insulated at both ends of the predetermined unit side 11, forming a double barrier effect. Even if there are large-size metal residues and / or small-size metal residues at the transmitting electrode 3 and the receiving electrode 4 in the touch panel, it will not cause the touch panel to form an additional conductive path, thereby changing the electric field distribution between the transmitting electrode 3, the receiving electrode, and the virtual electrode 5, resulting in a short circuit between the transmitting electrode 3, the receiving electrode 4, and the virtual electrode 5, and an abnormal increase in the touch capacitance value formed between the transmitting electrode 3 and the receiving electrode 4, thus affecting the touch function.
[0078] In a specific embodiment, a virtual electrode 5 is provided on the touch layer, and a series double break is provided on a part of the predetermined unit side 11, which can also achieve the purpose of insulating and isolating adjacent electrode regions and reduce costs.
[0079] In another specific embodiment, a virtual electrode 5 is provided on the touch layer, and a series double break is provided on all the predetermined unit sides 11, which can also achieve the purpose of insulating and isolating adjacent electrode regions and improve the touch stability.
[0080] Example 3
[0081] Based on the above-mentioned Embodiment 1 and Embodiment 2, an example is described in detail in which the entire predetermined unit side 11 is deleted in this specific embodiment.
[0082] As Figure 9 shown, the predetermined unit side 11 provided at a predetermined position on the metal grid is deleted, that is, the unit side where the junction between the transmitting electrode 3 and the receiving electrode 4 is located is deleted, or the unit side where the junction between the transmitting electrode 3 and / or the receiving electrode 4 and the virtual electrode 5 is located is deleted, which can also achieve the purpose of reducing the possibility of metal residues affecting the touch accuracy, and can have a good shielding effect on metal residues whose length does not exceed the length of the predetermined unit side 11, avoiding the possibility that the vast majority of metal residues cover the break, thereby improving the touch accuracy.
[0083] The above is a schematic description of the present invention, and it is not limited thereto. Only one of the implementation manners of the present invention is shown in the drawings. If those skilled in the art, without departing from the gist of the present invention, propose a structural form similar to this technical solution, it shall fall within the protection scope of the present invention.
