[0027] The present application provides a touch panel and a display device. Figures 1 to 3 Various embodiments of a touch panel and a display device are described.

[0028] See also Figures 1 to 3A touch panel provided in an embodiment of the present application includes: a substrate 1; a touch layer 2, which is arranged on one side of the substrate 1, and the touch layer 2 includes a first electrode block 21 and a second electrode block 22 arranged in the same layer and insulated from each other; wherein the first electrode block 21 includes a first sub-portion 211 extending along a first direction X and a second sub-portion 212 extending along a second direction Y, and along the second direction Y, at least two second sub-portions 212 arranged at intervals along the first direction X are connected to both sides of the first sub-portion 211, respectively, and each second electrode block 22 is respectively arranged in an area surrounded by the first sub-portion 211 and two adjacent second sub-portions 212 along the first direction X, and the first direction X and the second direction Y intersect.

[0029] The touch panel provided by the embodiment of the present invention includes a substrate 1 and a touch layer 2. The first electrode block 21 includes a first sub-portion 211 extending along a first direction X and a second sub-portion 212 extending along a second direction Y. By arranging each second electrode block 22 in an area surrounded by the first sub-portion 211 and the second sub-portion 212, an electric field is formed between each second electrode block 22 and the first electrode block 21 to realize a touch function. One first electrode block 21 can correspond to a plurality of second electrode blocks 22, thereby improving the utilization efficiency of the first electrode block 21. The first electrode block 21 and the second electrode block 22 are arranged on the same layer without the need to arrange other conductive layers M, thereby effectively reducing the thickness of the touch panel and making the touch panel more flexible. In addition, the circuit breakage and difficult-to-detect micro-circuit breakage caused by the double-layer metal routing and line switching vias in the prior art can be avoided, thereby effectively ensuring the electrical performance of the touch panel and improving the performance of the touch panel. Furthermore, reducing the film layer can simplify the process, improve the touch panel preparation yield, save raw materials, and reduce costs.

[0030] The first electrode block 21 and the second electrode block 22 can be prepared together through the same process, and the first electrode block 21 and the second electrode block 22 can be prepared using the same material to reduce costs.

[0031] Optionally, the first electrode block 21 includes a first sub-portion 211 and at least four second sub-portions 212 disposed on both sides of the first sub-portion 211 .

[0032] The substrate 1 can be a hard substrate, such as a glass substrate, or a flexible substrate, and its material can be polyimide, polystyrene, polyethylene terephthalate, polyparaxylene, polyethersulfone or polyethylene naphthalate. The substrate 1 is mainly used to support the device disposed thereon.

[0033] It is understandable that the embodiment of the present invention adopts a mutual capacitance electrode form, that is, one of the first electrode block 21 and the second electrode block 22 is a touch driving electrode, and the other is a touch sensing electrode, and the touch position is determined by detecting the capacitance change between the touch driving electrode and the touch sensing electrode.

[0034] In this embodiment, a plurality of first electrode blocks 21 may be arranged along the second direction Y, and each first electrode block 21 may correspond to a plurality of second electrode blocks 22 located in the area surrounded by the first sub-portion 211 and the second sub-portion 212. The specific number of first electrode blocks 21 and second electrode blocks 22 needs to be set according to the actual size of the touch panel to ensure that the touch area of ​​the touch panel meets the requirements.

[0035] Second electrode blocks 22 adjacent to each other along the first direction X may be separated by second sub-portions 212 to avoid mutual interference. Second electrode blocks 22 adjacent to each other along the second direction Y may be separated by first sub-portions 211 among second electrode blocks 22 corresponding to the same first electrode block 21 .

[0036] See also Figure 2 In some optional embodiments, the touch layer 2 further includes a touch signal line 3 disposed in the same layer as the first electrode block 21, the touch signal line 3 includes a first touch line 31 and a second touch line 32, the first touch line 31 is electrically connected to the first electrode block 21, and the second touch line 32 is electrically connected to the second electrode block 22. In some optional embodiments, at least two first electrode blocks 21 are arranged at intervals along the second direction Y, and at least part of the second touch line 32 is located in the interval between adjacent first electrode blocks 21 along the second direction Y.

[0037] In this embodiment, the touch signal line 3 and the first electrode block 21 are arranged in the same layer, that is, the touch signal line 3 and the first electrode block 21 and the second electrode block 22 can be prepared together through the same process, and the touch signal line 3 and the first electrode block 21 and the second electrode block 22 can be prepared with the same material to reduce costs.

[0038] It should be noted that at least part of the second touch lines 32 are located in the intervals between adjacent first electrode blocks 21 along the second direction Y, that is, the second touch lines 32 can be routed between the first electrode blocks 21 without having to be routed entirely through the left and right frame portions of the touch panel, which effectively reduces the touch panel frame width and is conducive to the realization of a narrow frame.

[0039] Optionally, the touch panel further includes a control chip 4, the touch signal lines 3 are electrically connected to the control chip 4, and some second touch lines 32 can be routed between the first electrode blocks 21 and directly connected to the control chip 4 without passing through the left and right frames of the touch panel.

[0040] Each first electrode block 21 can be electrically connected to the control chip 4 through the first touch line 31, and the first sub-section 211 and each second sub-section 212 in the first electrode block 21 are an electrically connected whole, and the same touch signal can be sent and received through the first touch line 31. Optionally, the first touch line 31 is electrically connected to the first sub-section 211 to reduce the routing length of the first touch line 31, so as to facilitate connection with the control chip 4.

[0041] Each second electrode block 22 is electrically connected to the control chip 4 through a second touch line 32 . The second touch lines 32 may be routed along the second direction Y from both sides of the first sub-portion 211 according to different positions of the second electrode blocks 22 .

[0042] Optionally, when the first electrode block 21 is a touch driving electrode and the second electrode block 22 is a touch sensing electrode, the control chip 4 sends a touch driving signal to the touch driving electrode through the first touch line 31, and transmits the touch sensing signal generated by the touch sensing electrode that forms a mutual capacitance electrode pair with the touch driving electrode back to the control chip 4 through the second touch line 32. At this time, the touch position is determined by detecting the capacitance change between the touch driving electrode and the touch sensing electrode.

[0043] Optionally, along the second direction Y, at least a portion of the second touch lines 32 are located between two adjacent second electrode blocks 22 .

[0044] It should be noted that, in this embodiment, two adjacent second electrode blocks 22 may be two second electrode blocks 22 located in areas defined by different first electrode blocks 21 , and the second touch line 32 may be routed using the gap between the two adjacent second electrode blocks 22 .

[0045] Optionally, the second touch line 32 includes a first segment L1 extending along the second direction Y and a second segment L2 extending along the first direction X, the first segment L1 and the second segment L2 are connected, the first segment L1 is connected to the second electrode block 22 , and the second segment L2 is connected to the control chip 4 .

[0046] The angle between the first section L1 and the second section L2 may be greater than or equal to 90° to reduce bending stress and avoid fracture of the first section L1 and the second section L2.

[0047] In some optional embodiments, the second touch line 32 includes a first sub-touch line and a second sub-touch line; the first sub-touch line and the second sub-touch line are respectively arranged on two opposite sides of the first electrode block 21 along the second direction Y, and the first sub-touch line and the second sub-touch line are respectively electrically connected to the second electrode blocks 22 located on two opposite sides of the first electrode block 21 along the second direction Y.

[0048] In this embodiment, since the second electrode blocks 22 are provided on both sides of the first sub-portion 211 of the first electrode block 21 along the second direction Y, the first sub-touch line, the second sub-touch line and the second electrode block 22 can be respectively provided on both sides of the first sub-portion 211 along the second direction Y to reduce the length of the touch line and facilitate the second electrode block 22 to be connected to the control chip 4 through the first sub-touch line or the second sub-touch line.

[0049] See also Figure 2 In some optional embodiments, the second sub-portions 212 located on both sides of the first sub-portion 211 are staggered along the first direction X.

[0050] It should be noted that the setting position of the second sub-portion 212 will affect the position of the corresponding second electrode block 22. When the second sub-portions 212 located on both sides of the first sub-portion 211 are at least staggered along the first direction X, the second electrode blocks 22 corresponding to the adjacent second sub-portions 212 and the defined area of ​​the first sub-portion 211 will also be at least partially staggered along the first direction X, so as to improve the uniformity of the distribution of the second sub-portions 212 and the second electrode blocks 22, and avoid mutual interference between the second electrode blocks 22 correspondingly arranged in the same first electrode block 21 and adjacent along the first direction X.

[0051] See also Figure 2 In some optional embodiments, along the second direction Y, the length of the second sub-section 212 is greater than the length of the second electrode block 22; and / or, in the second sub-section 212 located on the same side of the first sub-section 211, along the first direction X, the distance between two adjacent second sub-sections 212 is greater than the length of the second electrode block 22.

[0052] In this embodiment, the length of the second sub-portion 212 and the distance between two adjacent second sub-portions 212 along the first direction X can be increased so that all the second electrode blocks 22 are located within the area defined by the second sub-portion 212 and the first sub-portion 211, thereby ensuring that the capacitance between the first electrode block 21 and the second electrode block 22 meets the requirements and improves the accuracy of touch control. In addition, the distance between two adjacent second sub-portions 212 along the first direction X is limited to be greater than the length of the second electrode block 22, and sufficient space can be reserved for the preparation of the second electrode block 22 to avoid interference between the second electrode block 22 and the first electrode block 21 due to factors such as process accuracy and errors.

[0053] See also Figure 3 In some optional embodiments, along the direction away from the substrate 1 , the touch layer 2 includes a stacked touch substrate C and a conductive layer M, and the first electrode block 21 and the second electrode block 22 are both arranged on the same layer as the conductive layer M.

[0054] In this embodiment, the first electrode block 21 and the second electrode block 22 are both disposed in the same layer as the conductive layer M, which means that the first electrode block 21 and the second electrode block 22 can be prepared together with the conductive layer M through the same process, and the first electrode block 21 and the second electrode block 22 can be prepared with the conductive layer M using the same material to reduce costs. The patterned first electrode block 21 and the second electrode block 22 are formed by photolithography or dry etching.

[0055] Optionally, the conductive layer M can be made of ITO (Indium Tin Oxide) material. ITO has high light transmittance and can effectively improve the light transmittance of the display panel to ensure the display effect. Of course, the conductive layer M can also be made of other materials, such as molybdenum, titanium, aluminum, silver and other metal materials.

[0056] Optionally, the material of the touch substrate C includes at least one of silicon nitride, silicon oxide, and silicon oxynitride.

[0057] In some optional embodiments, the opposite edges of the first sub-portion 211 and the second electrode block 22 are parallel; and / or the opposite edges of the second sub-portion 212 and the second electrode block 22 are parallel.

[0058] It can be understood that the edges of the first sub-portion 211 and the second electrode block 22 are parallel to each other to ensure that the interval between the first sub-portion 211 and the second electrode block 22 is evenly set, thereby improving the utilization rate of the space and thus improving the touch PPI. For example, the edges of the first sub-portion 211 and the second electrode block 22 can be straight edges and they are parallel to each other, or the edges of the first sub-portion 211 and the second electrode block 22 can be curved edges and they have the same curvature. Similarly, the edges of the second sub-portion 212 and the second electrode block 22 can be parallel to each other, and the interval between the second sub-portion 212 and the second electrode block 22 can be evenly set to improve the utilization rate of the space and thus improve the touch PPI.

[0059] Optionally, the first sub-portion 211 and the second sub-portion 212 both include a rectangle, and / or the second electrode block 22 includes a rectangle, so that the first electrode block 21 and the second electrode block 22 are regularly arranged, thereby reducing the difficulty of preparation.

[0060] Optionally, the first electrode block 21 and the second electrode block 22 include a metal grid structure, which can improve the light transmittance of the display panel.

[0061] Optionally, an array layer 5 , a light-emitting functional layer 6 and a packaging layer are stacked between the substrate 1 and the touch layer 2 .

[0062] The array layer 5 may include a driving circuit. Exemplarily, the driving circuit provided in the array layer 5 includes a transistor T and a storage capacitor. The transistor T includes an active layer Z, a gate G, a source S and a drain D. The material of the source S and the gate G may include a combination of one or more of molybdenum, titanium, aluminum, copper, etc. The gate G of the transistor T is usually used to receive a control signal so that the transistor T is turned on or off under the control of the control signal. One of the source S and the drain D of the thin film transistor is connected to the light-emitting functional layer 6 to control the normal light emission of the light-emitting functional layer 6.

[0063] Optionally, the light-emitting functional layer 6 includes a first electrode layer 61 , a light-emitting layer 62 and a second electrode layer 63 which are stacked in a direction away from the substrate 1 .

[0064] Optionally, the encapsulation layer is used to encapsulate and protect the light-emitting layer 62. The encapsulation layer F includes a first encapsulation layer, and the material of the first encapsulation layer includes an inorganic material. The inorganic material can be silicon nitride, silicon oxide, silicon oxynitride and other materials, and can be formed by a CVD (Chemical Vapor Deposition) process.

[0065] Optionally, the encapsulation layer F further comprises a second encapsulation layer located on the side of the first encapsulation layer away from the substrate 1, and the material of the second encapsulation layer comprises an organic material.

[0066] Optionally, the encapsulation layer F also includes a third encapsulation layer located on the side of the second encapsulation layer away from the substrate 1, and the material of the third encapsulation layer includes an inorganic material. Continuing to add an inorganic encapsulation layer outside the organic encapsulation layer can further improve the encapsulation effect of the encapsulation layer; in this embodiment, the material of the third encapsulation layer can be the same as or different from the material of the first encapsulation layer, and there is no special limitation.

[0067] Optionally, the material of the first encapsulation layer is the same as the material of the third encapsulation layer, so that the first encapsulation layer and the third encapsulation layer can be prepared using the same equipment, which can simplify the preparation process of the display panel.
