Therefore, this application is intended to cover modifications and variations falling within the scope of the corresponding claims (the claimed technical solutions) and their equivalents. It should be noted that the embodiments provided in this application can be combined with each other without contradiction.

[0029] This application provides a display panel and a display device, which will be described below in conjunction with the accompanying drawings. Figures 1 to 5 Various embodiments of the display panel and display device will be described.

[0030] Please see Figures 1 to 3 The present application provides a display panel including: a substrate 1; an array layer 2 disposed on one side of the substrate 1, the array layer 2 including fixed potential signal lines 3; touch signal lines 4 disposed on the same layer as at least a portion of the fixed potential signal lines 3, and the touch signal lines 4 being at least partially disposed between two adjacent fixed potential signal lines 3; and a light-emitting functional layer 5 disposed on the side of the array layer 2 away from the substrate 1.

[0031] The display panel provided in this embodiment of the invention includes a substrate 1, an array layer 2, touch signal lines 4, and a light-emitting functional layer 5. The touch signal lines 4 are integrated into the array layer 2 to reduce the overall thickness of the display panel and improve the integration. By setting the touch signal lines 4 and at least some fixed potential signal lines 3 in the same layer, and at least some of the touch signal lines 4 are located between two adjacent fixed potential signal lines 3, the fixed potential signal lines 3 are voltage signals with fixed potentials, which are not affected by the signals of the touch signal lines 4. Furthermore, the two fixed potential signal lines 3 can be used as signal shielding to effectively shield the touch signals of the touch signal lines 4 in the array layer 2 from the display signals of other signal traces in the array layer 2, preventing touch and display malfunctions and effectively improving the performance of the display panel.

[0032] In this embodiment, the touch signal line 4 and the fixed potential signal line 3 are arranged on the same layer, which only represents their relative positional relationship. Their materials and manufacturing processes can be the same to reduce costs, or they can be different to facilitate manufacturing. There are no special limitations.

[0033] Optionally, substrate 1 can be a rigid substrate, such as a glass substrate; or it can be a flexible substrate, made of polyimide, polystyrene, polyethylene terephthalate, poly(p-xylene), polyethersulfone, or polyethylene naphthalate. Substrate 1 is mainly used to support the devices mounted on it.

[0034] Optionally, the array layer 2 includes at least two conductive layers and an insulating layer disposed between two adjacent conductive layers; the fixed potential signal line 3 and any one of the at least two conductive layers are disposed on the same layer.

[0035] Depending on actual needs, array layer 2 can be set with two, three, four or more layers for setting pixel circuits and signal lines. Fixed potential signal line 3 can be set on the same layer as any of the conductive layers. Fixed potential signal line 3 can be formed by patterning the conductive layers.

[0036] The material of the conductive layer may include at least one of copper, silver, aluminum, molybdenum, and nickel. That is, the material of the conductive layer may be a single metal, an alloy, or a metal stack structure. For example, the conductive layer may include titanium, aluminum, titanium stack structure, copper-nickel alloy, or molybdenum, aluminum, and molybdenum stack structure.

[0037] Please see Figure 2 Optionally, array layer 2 may include a driving circuit. For example, array layer 2 may include a first conductive layer M1, a second conductive layer M2, and a third conductive layer M3 disposed on one side of substrate 1 and stacked thereon. An insulating layer is disposed between adjacent conductive film layers. Exemplarily, the pixel driving circuit disposed on array layer 2 includes a transistor and a storage capacitor C. The transistor includes an active layer Y, a gate G, a source S, and a drain D. The materials of the source S and the gate G may include one or more combinations of molybdenum, titanium, aluminum, copper, etc. The gate G of the transistor is typically used to receive a control signal, causing the transistor to turn on or off under the control of the control signal. One of the source S and drain D of the thin-film transistor is connected to the light-emitting unit to control the normal light emission of the light-emitting unit.

[0038] The storage capacitor C includes a first plate C1 and a second plate C2. As an example, the gate G and the first plate C1 can be located in the first conductive layer M1, the second plate C2 can be located in the second conductive layer M2, and the source S and drain D can be located in the third conductive layer M3.

[0039] The touch signal line 4 and the fixed potential signal line 3 can be disposed on the same layer as any one of the first conductive layer M1, the second conductive layer M2, and the third conductive layer M3. For example, the touch signal line 4 and the fixed potential signal line 3 can be disposed on the third conductive layer M3 located on the top layer to reduce the distance between the touch signal line 4 and the user touch film layer and ensure the accuracy of touch.

[0040] Optionally, the light-emitting functional layer 5 includes one or more of the following: an electron injection layer, an electron transport layer, a light-emitting material layer, a hole blocking layer, an electron blocking layer, a hole transport layer, and a hole injection layer. The specific selection can be based on the specific type of the light-emitting layer 52 and is not particularly limited. The electron injection layer, electron transport layer, and hole blocking layer can be disposed between the second electrode layer 53 and the light-emitting material layer. The electron blocking layer, hole transport layer, and hole injection layer can be disposed between the first electrode layer 51 and the light-emitting material layer.

[0041] The material of the first electrode layer 51 is generally a material with a high work function to improve hole injection efficiency. It can be gold (Au), platinum (Pt), titanium (Ti), silver (Ag), indium tin oxide (ITO), zinc tin oxide (IZO), or a transparent conductive polymer (such as polyaniline). For example, the first electrode layer 51 can be made of ITO-Ag-ITO composite material, without any special limitations.

[0042] The material of the second electrode layer 53 can be one of the following metals: silver (Ag), aluminum (Al), lithium (Li), magnesium (Mg), ytterbium (Yb), calcium (Ca), or indium (In). It can also be an alloy of the aforementioned metals, such as magnesium-silver alloy (Mg / Ag) or lithium-aluminum alloy (Li / Al). This embodiment does not limit the material in this regard.

[0043] Please see Figures 3 to 5 In some optional embodiments, the fixed potential signal line 3 includes at least one of a high-level power supply signal line 31, a low-level power supply signal line 32, and an initialization power supply signal line 33.

[0044] Among them, the high-level power signal line 31, i.e., the PVDD signal line, is electrically connected to the source of the PMOS transistor when the driving transistor is a PMOS transistor, and the second electrode layer 53 is electrically connected to the low-level power signal line 32, i.e., the PVSS signal line. When the driving transistor is an NMOS transistor, the source is connected to the low-level power signal line 32, and the second electrode layer 53 is electrically connected to the high-level power signal line 31. The initialization power signal line 33 is used to initialize the transistor and / or the first electrode layer 51, and the specific settings depend on the pixel circuit configuration used in the display panel.

[0045] Since the high-level power signal line 31, the low-level power signal line 32, and the initialization power signal line 33 are all connected to a fixed potential, the touch signal line 4 can be shielded by any two of the high-level power signal line 31, the low-level power signal line 32, and the initialization power signal line 33. This prevents the touch signal line 4 from interfering with other non-fixed potential signal lines 3, such as data lines (DATA signal lines), which would affect the touch or display effect.

[0046] Optionally, the touch signal line 4 is located between two fixed-potential signal lines 3 that transmit the same signal to ensure the stability of signal transmission. For example, the touch signal line 4 is located between two high-level power signal lines 31, or between two low-level power signal lines 32, or between two initialization power signal lines 33, which facilitates fabrication.

[0047] In some alternative embodiments, considering the limited wiring space and the fact that fixed-potential signal lines 3 transmitting different signals may need to be electrically connected to different components, their wiring positions are limited. Therefore, the touch signal line 4 can be located between two fixed-potential signal lines 3 transmitting different signals. Depending on the actual wiring, the touch signal line 4 can be located between adjacent high-level power signal lines 31 and low-level power signal lines 32, such as... Figure 4 As shown; or, the touch signal line 4 is located between the adjacent high-level power signal line 31 and the initialization power signal line 33, such as... Figure 5 As shown, this is to reduce wiring difficulty and facilitate signal connection.

[0048] Of course, the touch signal line 4 can also be located between the low-level power signal line 32 and the initialization power signal line 33, without any special limitation.

[0049] Please see Figures 2 to 3 In some optional embodiments, the array layer 2 further includes a data signal line 6, which is disposed in the same layer as the fixed potential signal line 3 and the touch signal line 4, and at least one fixed potential signal line 3 is provided between the data signal line 6 and the touch signal line 4 in a direction parallel to the plane of the substrate 1.

[0050] Understandably, data signal line 6, or DATA signal line, is used to transmit data signals and control the light emission of the light-emitting functional layer 5. However, the signal of data signal line 6 is subject to change, and the signal of touch signal line 4 may interfere with the signal of data signal line 6. Therefore, at least one fixed-potential signal line 3 needs to be provided between data signal line 6 and touch signal line 4 in a direction parallel to the plane of substrate 1. This fixed-potential signal line 3 can be used to shield the touch signal from interfering with the data signal line 6, ensuring the display effect.

[0051] For example, a high-level power signal line 31 can be provided between the data signal line 6 and the touch signal line 4; or a low-level power signal line 32 can be provided between the data signal line 6 and the touch signal line 4; or an initialization power signal line 33 can be provided between the data signal line 6 and the touch signal line 4. Alternatively, at least two fixed-potential signal lines 3 can be provided between the data signal line 6 and the touch signal line 4. These can be at least two fixed-potential signal lines 3 transmitting the same signal, or at least two fixed-potential signal lines 3 transmitting different signals. For example, a high-level power signal line 31 and a low-level power signal line 32 can be provided between the data signal line 6 and the touch signal line 4.

[0052] Please see Figure 4In some optional embodiments, the distance between the touch signal line 4 and the adjacent fixed potential signal line 3 is equal everywhere along the extension direction perpendicular to the touch signal line 4, so as to improve space utilization and avoid mutual interference between the touch signal line 4 and the potential signal line.

[0053] Optionally, along the extension direction perpendicular to the touch signal line 4, the distance between the touch signal line 4 and the adjacent fixed potential signal line 3 is greater than or equal to 2μm and less than or equal to 5μm, in order to meet the process accuracy requirements, facilitate the fabrication, and avoid problems such as the touch signal line 4 and the adjacent fixed potential signal line 3 being connected or short-circuited during the fabrication process.

[0054] For example, along the extension direction perpendicular to the touch signal line 4, the distance between the touch signal line 4 and the adjacent fixed potential signal line 3 can be any one of 2μm, 2.5μm, 3μm, 3.5μm, 4μm, 4.5μm, or 5μm.

[0055] In some optional embodiments, the display panel includes adjacent display areas and non-display areas, the display areas including adjacent first display areas and second display areas; the light-emitting functional layer 5 includes light-emitting units, the arrangement density of light-emitting units in the first display area is greater than the arrangement density of light-emitting units in the second display area, and the touch signal line 4 is at least provided in the second display area.

[0056] It should be noted that since additional touch signal lines 4 need to be set in array layer 2, and the wiring space of array layer 2 corresponds to the arrangement of light-emitting units, in order to leave space for touch signal lines 4, it is necessary to compress the light-emitting units, that is, reduce the arrangement density of light-emitting units, so that the distance between adjacent light-emitting units is larger, which in turn leaves some space in array layer 2 for setting touch signal lines 4, and the touch signal lines 4 are set at least in the second display area.

[0057] Optionally, considering that the low-level power signal line 32 is usually located in the non-display area, if the low-level power signal line 32 is located in the display area to shield the touch signal line 4 signal, the low-level power signal line 32 also needs to be located in the second display area where there is more space.

[0058] In this embodiment, the initialization power signal line 33, the low-level power signal line 32, and the high-level power signal line 31 extend in the same direction in at least a portion of the area. However, in the prior art, the initialization power signal line 33 and the high-level power signal line 31 usually intersect in their extension directions. Therefore, the initialization power signal line 33 and the high-level power signal line 31 are usually set on different layers. Thus, in order to accommodate the initialization power signal line 33, which extends in the same direction as the high-level power signal line 31, the initialization power signal line 33 also needs to be placed in the second display area, which has more space.

[0059] Please see Figure 2 In some optional embodiments, the display panel further includes a touch electrode layer 7, which is disposed on the side of the light-emitting functional layer 5 away from the substrate 1. The touch electrode layer 7 includes a touch electrode block 71, and the touch signal line 4 is electrically connected to the touch electrode block 71.

[0060] In this embodiment, the touch electrode block 71 and the touch signal line 4 can be connected in the display area through a via or in the non-display area, without any particular limitation.

[0061] Optionally, an encapsulation layer is provided between the light-emitting functional layer 5 and the touch electrode layer 7. The encapsulation layer is used to encapsulate and protect the light-emitting layer 52. The encapsulation layer may include inorganic materials, such as silicon nitride, silicon oxide, and silicon oxynitride, and may be formed using CVD (Chemical Vapor Deposition) process.

[0062] Optionally, the encapsulation layer F includes a first encapsulation layer, the material of which includes an inorganic material.

[0063] Optionally, the encapsulation layer F further includes a second encapsulation layer located on the side of the first encapsulation layer opposite to the substrate 1. The material of the second encapsulation layer includes an organic material. The organic material can be made of resin or polymeric organic material, and can be formed using IJP (Inkjet printing) technology.

[0064] Optionally, the encapsulation layer F may also include a third encapsulation layer located on the side of the second encapsulation layer away from the substrate 1. The material of the third encapsulation layer includes inorganic materials. Adding an inorganic encapsulation layer outside the organic encapsulation layer can further improve the encapsulation effect of the encapsulation layer F. In this embodiment, the material of the third encapsulation layer may be the same as or different from the material of the first encapsulation layer, and there is no special limitation.

[0065] Optionally, the materials of the first encapsulation layer and the third encapsulation layer are the same, so that the first encapsulation layer and the third encapsulation layer can be manufactured using the same equipment, which can simplify the manufacturing process of the display panel.

[0066] Optionally, the touch electrode layer 7 can be disposed on the same layer as the first electrode layer 51, or the touch electrode layer 7 and the second electrode layer 53 can be disposed on the same layer to further reduce the thickness of the display panel.

[0067] The display panel provided in the embodiments of the present invention can be an organic light-emitting diode (OLED) display panel, a quantum dot light-emitting diode (QLED) panel, or a micro flat panel display panel (Micro-OLED or Micro-LED), etc.

[0068] The display panel provided in this application embodiment can be applied to mobile phones or any electronic product with display function, including but not limited to the following categories: televisions, laptops, desktop monitors, tablets, digital cameras, smart bracelets, smart glasses, vehicle displays, medical devices, industrial control equipment, touch interactive terminals, etc. This application embodiment does not make any special limitations on this.
