Description

Technical Field

[0001] This application relates to the field of touch technology, and in particular, to a touch structure, a display panel, and an electronic device. Background Art

[0002] A touch screen is an inductive display device that combines display and touch functions. When a finger or a specific inductive contact touches a certain potential on the screen, the inductive system on the screen can implement corresponding display operations according to a pre-programmed algorithm. Fast, convenient, and diversified human-computer interaction has given a new look to the display panel. Touch panels have a wide range of applications in fields such as portable electronic devices, public information query, multimedia teaching, and conference display, and have great market potential.

[0003] Common touch display screens are generally divided into external touch screens, on-cell touch screens, in-cell touch display panels, and hybrid touch screens. Among them, the external touch screen is independent of the display and can be fixed to the display by external attachment or lamination to form a touch screen. The on-cell touch screen technology generally refers to capacitive touch technology, which manufactures touch sensors on the liquid crystal cell, that is, touch technology on the glass surface or even the polarizer.

[0004] Common on-cell touch screen structures include single-point touch technology and multi-point touch technology. Among them, single-point touch technology is a single-layer transparent electrode film layer. This technology has low cost and high light transmittance, but poor sensitivity and poor anti-interference ability. Multi-point touch technology is a single-sided double-layer transparent electrode film layer, and this technology has high cost. Summary of the Invention

[0005] The purpose of this application is to provide a touch structure, a display panel, and an electronic device, and this touch structure has low cost, high accuracy, and high sensitivity.

[0006] To this end, in a first aspect, an embodiment of this application provides a touch structure, a metal mesh layer, on which a first insulating layer, a touch transparent electrode layer, and a second insulating layer are sequentially arranged. A plurality of induction sensors and a plurality of reading sensors are arranged in the touch transparent electrode layer, and each of the induction sensors and each of the reading sensors are arranged in a staggered manner.

[0007] In a possible implementation manner, the projection shape of one of the induction sensors and the reading sensors is rectangular, and the projection shape of the other is rhombic.

[0008] In a possible implementation manner, the materials of the first insulating layer and the second insulating layer include perfluoroalkoxy hydrocarbon, silicon nitride, silicon oxide, or inorganic materials.

[0009] In a possible implementation, the film thickness of the second insulating layer is greater than that of the first insulating layer.

[0010] In a possible implementation, a protective film is provided on the second insulating layer.

[0011] In a second aspect, an embodiment of the present application provides a circuit board. The circuit board includes the touch structure as described in the first aspect. The display panel further includes an array substrate, a color filter substrate, and a spacer layer disposed between the array substrate and the color filter substrate. The touch structure is disposed on a side of the color filter substrate away from the array substrate.

[0012] In a possible implementation, a color resist layer is integrated on the array substrate.

[0013] In a possible implementation, a spacer layer is integrated on the array substrate.

[0014] In a possible implementation, a light-shielding layer is integrated on the array substrate.

[0015] In a third aspect, an embodiment of the present application provides an electronic device. The electronic device includes the touch structure as described in the first aspect.

[0016] According to the touch structure, display panel, and electronic device provided by the embodiments of the present application, the touch structure forms a metal grid through a metal grid layer to fix the positions of the induction sensor and the reading sensor, and provide electrical conductivity to form a wire circuit. By disposing the first insulating layer between the metal grid layer and the touch transparent electrode layer, the parasitic capacitance between the metal grid layer and the touch transparent electrode layer can be reduced. The touch transparent electrode layer forms a bridge for the transmission of the induction sensor and the reading sensor, and realizes the touch induction and reading functions through the induction sensor and the reading sensor. A second insulating layer is disposed on a side of the touch transparent electrode layer away from the first insulating layer to protect the induction sensor and the reading sensor.

[0017] The touch structure provided by this embodiment can realize the touch induction and reading functions. Setting only one layer of touch transparent electrode layer can reduce costs. In addition, by staggering the induction sensors and the reading sensors, true multi-point support is achieved, so the accuracy and sensitivity are relatively high. Description of the Drawings

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.

[0028] First embodiment

[0029] As Figures 1-4As shown in the figure, an embodiment of the present application provides a touch structure, including a metal mesh layer 1. A first insulating layer 2, a touch transparent electrode layer 3, and a second insulating layer 4 are sequentially arranged on the metal mesh layer 1. A plurality of induction sensors 16 and a plurality of reading sensors 17 are arranged in the touch transparent electrode layer 3, and the induction sensors 16 and the reading sensors 17 are arranged in an interleaved manner.

[0030] The metal mesh layer 1 forms a metal mesh, forms an obvious bridge, fixes the positions of the induction sensors 16 and the reading sensors 17, and provides electrical conductivity to form a wire circuit. By arranging the first insulating layer 2 between the metal mesh layer 1 and the touch transparent electrode layer 3, the parasitic capacitance between the metal mesh layer 1 and the touch transparent electrode layer 3 can be reduced. The touch transparent electrode layer 3 forms a bridge for the transmission of the induction sensors 16 and the reading sensors 17, and realizes the induction and reading functions of touch through the induction sensors 16 and the reading sensors 17. A second insulating layer 4 is arranged on the side of the touch transparent electrode layer 3 away from the first insulating layer 2 to protect the induction sensors 16 and the reading sensors 17.

[0031] The touch structure provided in this embodiment can realize the induction and reading functions of touch. Only setting one layer of touch transparent electrode layer 3 can reduce costs. In addition, by arranging the induction sensors 16 and the reading sensors 17 in an interleaved manner, it supports true multi-point, so the accuracy and sensitivity are relatively high.

[0032] Among them, the metal mesh layer 1 can be made of a metal material, such as metal copper. Specifically, the metal mesh layer 1 can be a molybdenum layer, a copper layer, and a molybdenum layer arranged in sequence. The film thicknesses of each layer of the metal mesh layer 1 are 500 - 600 / 2500 - 3000 / 500 - 600 (Å). Of course, the molybdenum material can also be replaced with molybdenum nitride (MoN) or MTD.

[0033] The first molybdenum layer in the metal mesh layer 1 is used to isolate the copper layer and the glass of the substrate. Using the molybdenum layer as an intermediate medium, the film thickness of the molybdenum layer is 500 - 600 (Å). A copper layer is arranged on the molybdenum layer, and the thickness of the copper layer is 2500 - 3000 (Å) to ensure that the copper layer has sufficient current-carrying capacity, thermal management performance, mechanical strength, and reliability to meet the requirements of high-performance display technology. The molybdenum layer above the copper layer is the second molybdenum layer, and the thickness of the second molybdenum layer is 500 - 600 (Å) to prevent the diffusion of copper.

[0034] In addition, the metal mesh layer 1 can also be replaced with a metal-based mesh structure such as a nano-silver layer, a silver-based metal mesh, a copper-based metal mesh, an aluminum-based metal mesh, etc. The process of its metal mesh structure can be made by the metal screen printing method, and the metal film layer plated on the glass surface is screen printed to form the required mesh graphic structure.

[0035] The materials of the first insulating layer 2 and the second insulating layer 4 include perfluoroalkoxy hydrocarbons, silicon nitride, silicon oxide or inorganic materials. For example, the materials of both the first insulating layer 2 and the second insulating layer 4 are perfluoroalkoxy hydrocarbons (PFA). After using the PFA material, the distance between the metal mesh layer 1 and the touch transparent electrode layer 3 increases, the capacitance crosstalk between them is small, the sensitivity is higher, and the display effect of the touch screen is better.

[0036] Of course, the material of the first insulating layer 2 can also be the same as that of the gate insulating layer 8 (GI), such as silicon nitride (SINx) or silicon oxide (SiOx). After using this film layer, compared with using the PFA film layer, the cost is reduced and the process manufacturing is simple. The second insulating layer 4 can also be the same as the material of the passivation layer 10 (PV). The passivation layer 10 is usually composed of inorganic materials such as silicon dioxide (SiO2) or other polymer materials.

[0037] Among them, the film thickness of the first insulating layer 2 is 15000 - 16000 (Å). This thickness range helps to balance performance, cost and process requirements. The first insulating layer 2 is used to increase the distance between the metal mesh layer 1 and the touch transparent electrode layer 3. Of course, the film thickness of the second insulating layer 4 can be the same as that of the first insulating layer 2. In this application, the film thickness of the second insulating layer 4 is greater than that of the first insulating layer 2. The film thickness of the second insulating layer 4 is 17000 - 18000 (Å). By making the film layer thickness of the second insulating layer 4 greater than that of the first insulating layer 2, the underlying inductive sensor 16 and read sensor 17 can be protected, external moisture can be isolated. At the same time, thickening the second insulating layer 4 also helps to improve the electronic effect, reduce the touch leakage current, and reduce the transition of electronic energy.

[0038] The material of the touch transparent electrode layer 3 is indium tin oxide (ITO). The film thickness of the touch transparent electrode layer 3 is 700 - 1000 (Å). In order to ensure the transmittance of the touch transparent electrode layer 3, the film thickness of the touch transparent electrode layer 3 should not be too large. At the same time, considering the conductivity of the touch transparent electrode layer 3, the film thickness of the touch transparent electrode layer 3 should not be too thin. The inductive sensor 16 and the read sensor 17 in the touch transparent electrode layer 3 can be arranged in a staggered manner along the length direction or along the width direction.

[0039] Among them, the projected shapes of the inductive sensor 16 and the read sensor 17 are both rectangular or both rhombic. By setting the rectangular shape or the rhombic shape, more inductive sensors 16 and read sensors 17 can be arranged under the same size, ensuring the touch sensitivity.

[0040] A protective film 18 is provided on the second insulating layer 4. Specifically, after the touch structure is coated with a film, a protective film 18 needs to be added on the surface. The setting of this protective film 18 can prevent scratching when coating the color filter electrode layer on the side of the color filter substrate 6. The material of the protective film 18 can be polyethylene terephthalate (PET), or a combination of polyethylene terephthalate (PET) and polyurethane glue (PU glue). Among them, PET has good mechanical properties, and PU glue can prevent static electricity. Of course, the protective film 18 can also be a protective film 18 similar to that of an electronic paper display (EPD). This protective film 18 can prevent scratching and prevent water vapor pollution, etc. when coating the color filter electrode layer on the side of the color filter substrate 6.

[0041] In summary, the touch structure provided by the embodiment of the present application is simple in structure, easy to prepare, low in cost, high in accuracy and sensitivity. The protective film 18 provided on the touch structure can also prevent surface dust or other pollution and prevent surface scratching.

[0042] Second Embodiment

[0043] As Figures 1-4 shown, the embodiment of the present application also provides a display panel 100. The display panel 100 includes the touch structure as described in the foregoing embodiment. The display panel 100 further includes an array substrate 5, a color filter substrate 6, and a spacer layer 14 disposed between the array substrate 5 and the color filter substrate 6. The touch structure is disposed on the side of the color filter substrate 6 away from the array substrate 5.

[0044] The display panel 100 includes an array substrate 5. On the array substrate 5, a metal layer 7, a gate insulating layer 8, a semiconductor layer 9, a passivation layer 10, a color resist layer 11, a protective layer 12, a light-shielding layer 13, an array conductive layer, a spacer layer 14, a filter conductive layer 15, and a color filter substrate 6 are sequentially arranged. The touch structure is disposed on the color filter substrate 6.

[0045] As Figure 4 , wherein, the array substrate 5 (Array Glass) contains the basic driving circuit elements for product display. The material of the array substrate 5 can be glass. The array substrate 5 is mainly responsible for forming a thin-film transistor array (TFT Array). These TFT elements are used to control the voltage value (number of electrons) input by the driving chip, and the pixel electrode (Pixel ITO) is used to store these voltage values. On the Array Glass, millions of TFT elements and pixel electrodes are neatly arranged, and they cooperate together to control the alignment direction of the liquid crystal, thereby affecting the deflection of some light in the liquid crystal electric field.

[0046] Metal layer 7 (M1) During the manufacturing process of a TFT-LCD (Thin Film Transistor Liquid Crystal Display), metal layer 7 (M1) is an important part of the thin film transistor (TFT) circuit, used to form the source, drain, and gate connections of the transistor. Metal layer 7 is formed on the array substrate 5 through specific photolithography and etching processes to achieve the transmission and control of electrons. The material of metal layer 7 can be gold, aluminum, chromium, or molybdenum, etc.

[0047] The gate insulating layer 8 (GI) is used to isolate the gate from the semiconductor layer 9 and prevent current leakage. The material of the gate insulating layer 8 can include silicon nitride (SiNx) and silicon oxide (SiOx).

[0048] The material of the semiconductor layer 9 can include amorphous silicon (a-Si), low-temperature polycrystalline silicon (LTPS), or oxide semiconductor materials (such as IGZO). The semiconductor layer 9 not only controls current and signals but also affects the performance and efficiency of the display.

[0049] The passivation layer 10 (PV) is an insulating layer used to protect electronic components from the external environment (such as moisture, oxygen, etc.). The source and drain are disposed between the semiconductor layer 9 and the passivation layer 10. The passivation layer 10 is usually composed of inorganic materials such as silicon dioxide (SiO2) or other polymer materials. It covers structures such as fan-out traces, semiconductor layer 9, source, and drain to prevent them from physical damage and chemical corrosion. The passivation layer 10 also has vias to allow electrical connection to the underlying structures.

[0050] The color filter layer 11 is composed of red, green, and blue (RGB) color filters. Through the combination of these filters, a full-spectrum of colors can be produced. Each pixel is composed of three sub-pixels of red, green, and blue. By controlling the brightness and color of each sub-pixel, various colors and images can be presented.

[0051] Such as Figures 1-4, the color filter layer 11 can be integrated on the array substrate 5, that is, the color filter is integrated with the array substrate 5 (COA). Specifically, a color photoresist is coated on the completed array substrate 5 to form a color filter layer, which can improve the problem of low aperture ratio of traditional color filters. In the structure of a traditional liquid crystal display, the color filter layer is usually located on the front substrate, while the TFT is located on the back substrate. The COA technology fabricates the TFT and the color filter layer on the same glass array substrate 5. Since both the TFT and the color filter layer are on one piece of glass, they can be self-aligned, eliminating the alignment process, simplifying the manufacturing process, and improving product quality; it can effectively solve problems such as light leakage caused by alignment deviation in the cell process of the liquid crystal display device, and can significantly increase the display aperture ratio. Reducing the manufacturing steps can lower production costs; since the process of separately manufacturing the photoresist spacer layer is omitted, the COA technology can save photomasks, shorten the manufacturing time, and improve production efficiency.

[0052] The protective layer 12 (PFA) has excellent electrical insulation properties and realizes insulation and protection functions.

[0053] The light-shielding layer 13 (BM) is used to improve the contrast and color purity of the display panel 100. The black matrix is composed of an opaque black material and is placed between the RGB sub-pixels to prevent light of different colors from interfering with each other, and at the same time absorb excess light to avoid light leakage. In this way, each sub-pixel can display colors independently without mixing with the colors of other pixels, thereby improving the image quality.

[0054] The light-shielding layer 13 can be integrated on the array substrate 5, which can effectively avoid light leakage in curved display applications and increase the aperture ratio of the liquid crystal panel. The BOA technology forms black matrices on the array substrate 5. These black matrices are located around the TFT (thin film transistor) and are used to block the light from the backlight module below the array substrate 5 from shining on the active layer, as well as the interference from other unwanted light sources. The width of the light-blocking line can be shortened, thereby increasing the aperture ratio of the liquid crystal panel and reducing the backlight cost. In addition, double-layer shielding is achieved by covering the black matrix on the color filter layer 11, effectively avoiding light leakage caused by the gap between the data line and the light-blocking line. By setting the black matrix inside the pre-formed channels on the array substrate 5, the film thickness of the liquid crystal panel becomes uniform, improving the display effect of the liquid crystal panel.

[0055] When the light-shielding layer 13 is set on the color film substrate 6 side, marking is performed by laser, while when the light-shielding layer 13 is set on the array substrate 5 side, grouping can be performed by marking the group metal layer 7 or the RGB of the color filter layer 11. Therefore, the grouping accuracy can be improved, and the improvement of the grouping accuracy can effectively improve the contrast and penetration. In addition, the light-shielding layer 13 is above the color filter layer 11, which can effectively block the reflection of the RGB color filter.

[0056] The array conductive layer (Array ITO) is used to control the movement of liquid crystal molecules, provides a conductive path, and also ensures the precise control of display pixels and high-quality display of images.

[0057] The filter conductive layer 15 (CF ITO) is used to form an electrode on the color filter, and a common electrode made of ITO film is provided on the side of the color film substrate 6. The ITO film has high conductivity, high visible light transmittance, high mechanical hardness, and good chemical stability. The filter conductive layer 15 combines the conductivity of ITO and the color display function of CF.

[0058] A spacer layer 14 (PS) is provided between the array conductive layer and the filter conductive layer 15. The spacer layer 14 is used to support the cell thickness, and the photosensitive resin composition is used for the spacer layer 14. The spacer layer 14 is the micro convex lens technology made of photoresist. The PS technology can replace the traditional semi-transmissive / gray-scale exposure process, and different support height requirements can be achieved by using an ordinary full-transmissive mask, and the light-shielding effect is achieved, greatly saving the preparation cost, and can be used for curved or flexible display panels 100. Among them, the main spacers are formed by stacking two layers of color resist materials to line and cover the planarization layer and the black photoresist material to form a height, and the auxiliary spacers are formed by lining one layer of color resist and covering the planarization layer and the black photoresist material to form a height. The respective heights of the main / auxiliary spacers and the step difference between them can be adjusted by changing the size of the lining color resist and the thickness of the planarization layer.

[0059] The spacer layer 14 is integrated on the array substrate 5, that is, the photosensitive spacer (Photo Spacer) is directly integrated on the array substrate 5 by using the POA technology, which can replace the traditional semi-transmissive / gray-scale exposure process. Different support height requirements can be achieved by only using an ordinary full-transmissive mask, and the light-shielding effect is achieved, greatly saving the preparation cost. In addition, the electrical performance can be improved, the height and step difference can be adjusted, the uniformity and elasticity can be improved, and it has a good display effect, and can also be applied to the display of curved or flexible screens.

[0060] Currently, when integrating the spacer layer 14 onto the array substrate 5, since there is no black or other colors for marking, and because ITO is transparent, there is no way to perform alignment, and there will be a situation where it is difficult to capture the position of the marking points. In this application, a metal layer 7 is provided on the array substrate 5, and the metal layer 7 can emit light, thereby realizing alignment, solving the problem of difficult capture of the position of the marking points, and realizing the technology of integrating the spacer layer 14 onto the array substrate 5.

[0061] In summary, for the display panel 100 provided by the present application, there is only a color filter conductive layer on the side of the color filter substrate 6, while a touch film layer is normally plated on the opposite side of the color filter substrate 6. By adopting two structures of combining COA and POA, or combining COA, POA and BOA, the present application realizes minimizing the film layer structure on the side of the color filter substrate 6 as much as possible, and reducing risks such as scratches during the coating of the touch film layer.

[0062] The light-shielding layer 13 is on the side of the color filter substrate 6, and the alignment accuracy is not good enough. Under pressing, the black matrix is prone to shift or displacement, resulting in light leakage. When combined with the COA and POA technologies, if the data side of the COA product has a double-buffer structure (DBS) ITO shield, it can provide an additional shielding effect, reduce external electromagnetic interference, improve signal stability or enhance the antistatic ability of the panel, and can also improve the light leakage under pressing on the data side.
