Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all the embodiments of the heating part. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or it can be in a middle component. When a component is said to be "connected" to another component, it can be directly connected to the other component or it may be in a middle component.

[0029] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0030] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] Display panels have become dominant in the display industry due to their advantages such as small size, low power consumption, and low radiation. Therefore, they are often used in extremely low-temperature environments. The minimum operating temperature of a typical LCD screen is -20°C. Below -20°C, additional heaters are needed to ensure the display panel functions properly at low temperatures. Current heating methods involve attaching an ITO heater to the outside of the LCD screen, but this method is slow.

[0032] For reference Figure 1 The present invention provides a display panel 100, including a color filter substrate 10 and an array substrate 20; the color filter substrate 10 includes a first heating layer 11; the array substrate 20 includes a second heating layer 21; wherein the color filter substrate 10 and the array substrate 20 are disposed opposite to each other, and the first heating layer 11 and the second heating layer 21 are electrically connected.

[0033] The first heating layer 11 and the second heating layer 21 are transparent conductive materials, which can be carbon nanotube transparent conductive materials, oxide transparent conductive materials, metal transparent conductive materials, etc., without limitation. Specifically, oxide transparent conductive materials can be zinc oxide, tin oxide, indium tin oxide (ITO), etc., and metal transparent conductive materials can be thin films of metals such as silver, copper, and gold.

[0034] The color filter substrate 10 is used to provide color display, increase contrast, provide protection and insulation, and compensate for brightness differences, while the array substrate 20 is used to provide pixel control, heat dissipation and power management.

[0035] Optionally, the color filter substrate 10 and the array substrate 20 are arranged at intervals relative to each other, and the display panel 100 further includes a liquid crystal layer 30 disposed between the color filter substrate 10 and the array substrate 20. The liquid crystal layer 30 includes a plurality of liquid crystal molecules, and the liquid crystal molecules can change their arrangement with each other by changing the electric field or voltage, producing different degrees of optical transmission effect. The main function of the liquid crystal layer 30 is to adjust the display color, brightness, and saturation by controlling the transmission of light.

[0036] The display panel 100 of this invention has a first heating layer 11 disposed in the color filter substrate 10 and a second heating layer 21 disposed in the array substrate 20. The first heating layer 11 and the second heating layer 21 are electrically connected, forming a closed loop between the first heating layer 11 and the second heating layer 21. The heating cycle of the first heating layer 11 and the second heating layer 21 is realized by externally supplying voltage. Therefore, the display panel 100 of this invention has a fast heating speed. Moreover, by placing the first heating layer 11 inside the display panel 100, the thickness of the display screen with heater can also be reduced.

[0037] For reference Figure 1In one embodiment, the color filter substrate 10 includes a first substrate 12 and a color filter layer 13, at least a portion of the first heating layer 11 is stacked on the first substrate 12, and the color filter layer 13 is stacked on the portion of the first heating layer 11 corresponding to the first substrate 12.

[0038] The first substrate 12 is a transparent substrate with good optical transparency and mechanical stability, specifically a thin glass sheet or plastic, etc.

[0039] The color filter layer 13 serves to achieve color display, increase contrast, provide protection and insulation, and compensate for brightness differences. The color filter layer 13 may include an RGB pixel layer, a black matrix, an OC (overcoat) layer, a transparent conductive layer, and auxiliary layers. The RGB pixel layer is composed of R (red), G (green), and B (blue) primary color pixels arranged according to a certain rule. The black matrix is ​​a light-shielding layer located between the RGB pixels, used to prevent color crosstalk between pixels and improve color purity. The black matrix is ​​usually made of a high-absorbency material, such as black resin or metal oxide. The OC layer is stacked on the RGB pixel layer to improve the durability and chemical stability of the color filter substrate 10, and also to prevent the diffusion and discoloration of RGB pigments during long-term use. The transparent conductive layer can be zinc oxide, tin oxide, indium tin oxide (ITO), etc., and serves as a common electrode for all pixels and voltage signals. The auxiliary layer can be a hardening layer, a scratch-resistant layer, an anti-fingerprint layer, etc., and is used to improve the durability of the color filter substrate 10 and the user experience.

[0040] A portion of the first heating layer 11 is stacked on the first substrate 12, and another portion of the first heating layer 11 is used to extend toward the second heating layer 21, which helps to reduce the number of components used for the electrical connection between the first heating layer 11 and the second heating layer 21.

[0041] For reference Figure 1 In one embodiment, the color filter substrate 10 further includes a flexible layer 14, which is disposed on the side of the first heating layer 11 facing away from the first substrate 12.

[0042] The flexible layer 14 can be an ultra-thin metal, plastic, etc. Specifically, the plastic can be PI (polyimide).

[0043] The flexible layer 14 is provided correspondingly to the first heating layer 11, that is, the shape and size of the flexible layer 14 can be the same as those of the first heating layer 11.

[0044] The first heating layer 11 will not crack under a certain degree of bending. The flexible layer 14 is used to bend the portion of the first heating layer 11 that extends beyond the first substrate 12 and extend it in a direction close to the second heating layer 21. The flexibility of the flexible layer 14 bends part of the first heating layer 11 closer to the second heating layer 21. The flexible layer 14 can protect the first heating layer 11 while moving it closer to the second heating layer 21, which helps to simplify the manufacturing process of the display panel 100.

[0045] For reference Figure 1 In one embodiment, the color filter substrate 10 further includes an insulating layer 15, which is stacked on the side of the first heating layer 11 facing away from the flexible layer 14, and at least one end of the first heating layer 11 is exposed outside the insulating layer 15.

[0046] The material of the insulation layer 15 can be PVC (polyvinyl chloride), XLPE (cross-linked polyethylene), rubber, resin, etc., without restriction.

[0047] The insulating layer 15 may be flush with the side of the second heating layer 21 facing away from the first substrate 12, or it may not be flush with the side of the second heating layer 21 facing away from the first substrate 12; there is no restriction.

[0048] The insulating layer 15 is used to prevent the first heating layer 11 and the second heating layer 21 from directly contacting the color filter layer 13 of the color filter substrate 10 and the array layer 23 of the array substrate 20, thereby reducing the influence of the first heating layer 11 and the second heating layer 21 on the color filter layer 13 and the array layer 23.

[0049] When the first heating layer 11 and the insulating layer 15 are flattened, that is, when the first heating layer 11 and the insulating layer 15 are not bent, the projection of the insulating layer 15 in the direction perpendicular to the first heating layer 11 is located inside the first heating layer 11.

[0050] The insulating layer 15 is provided so that the end of the first heating layer 11 that extends beyond the insulating layer 15 can be electrically connected to the second heating layer 21. This allows the first heating layer 11 to exist in both directions parallel to and perpendicular to the first substrate 12, which helps to extend the size of the first heating layer 11 and make the heating effect of the display panel 100 better. At the same time, it avoids the first heating layer 11 from directly contacting the color filter layer 13, which would affect the performance of the color filter layer 13.

[0051] For reference Figure 1In one embodiment, the first heating layer 11 includes a first heating part 111 and a second heating part 112. The first heating part 111 is disposed on the side of the first substrate 12 facing the array substrate 20. The first heating part 111 is disposed corresponding to the first substrate 12. The second heating part 112 is connected to the end of the first heating part 111 and extends to the second heating layer 21 in a direction close to the array substrate 20.

[0052] The side of the first heating part 111 away from the first substrate 12 may be flush with the side of the second heating layer 21 away from the first substrate 12, or it may be away from the first substrate 12 relative to the side of the second heating layer 21 away from the first substrate 12, without limitation.

[0053] The first heating element 111 is disposed corresponding to the color filter layer 13. The flexible layer 14 is used to drive the second heating element 112 to extend in a direction close to the array substrate 20.

[0054] The first heating section 111 is used to heat the color filter layer 13, so that the color filter layer 13 still has good performance at low temperature. The second heating section 112 extends along the direction close to the array substrate 20, which helps to improve the problem of rapid heat dissipation around the heating process.

[0055] For reference Figure 1 In one embodiment, the second heating part 112 includes a first sub-heating part 1121 and a second sub-heating part 1122 connected to each other. One end of the first sub-heating part 1121 is connected to the first heating part 111, and the other end of the first sub-heating part 1121 is connected to the second sub-heating part 1122. The first sub-heating part 1121 extends in a direction close to the second heating layer 21, and the second sub-heating part 1122 is electrically connected to the second heating layer 21.

[0056] Specifically, the first sub-heating part 1121 extends in a direction close to the array substrate 20, and the second sub-heating part 1122 extends in a direction parallel to the array substrate 20.

[0057] An insulating layer 15 is provided on the side of the first sub-heating part 1121 facing away from the flexible layer 14, and no insulating layer 15 is provided on the side of the second sub-heating part 1122 facing away from the flexible layer 14, so that the second sub-heating part 1122 is used to electrically connect with the second heating layer 21.

[0058] The first sub-heating part 1121 is provided to provide a heating layer in the direction of the color filter substrate 10 toward the array substrate 20. The second sub-heating part 1122 is provided to provide electrical connection between the first heating layer 11 and the second heating layer 21, so as to realize the circulation of the heating layer. The first sub-heating part 1121 can also avoid the problem of rapid heat dissipation around the display panel 100, which helps to improve the performance of the display panel 100 at low temperatures.

[0059] For reference Figure 1 In one embodiment, the first heating layer 11 further includes a third heating part 113, which is disposed at one end of the first heating part 111 away from and / or close to the second heating part 112, and extends to the second heating layer 21 in a direction close to the array substrate 20.

[0060] Optionally, the third heating part 113 may be disposed opposite to the second heating part 112, and the third heating part 113 may also be connected to the second heating part 112.

[0061] Optionally, the third heating part 113 may be the same as or different from the second heating part 112.

[0062] Optionally, the first heating layer 11 further includes a fourth heating part and a second heating part. The second heating part 112, the third heating part 113, the fourth heating part and the fifth heating part are connected in sequence to form a closed receiving space. The receiving space contains a liquid crystal layer 30, etc. One end of the second heating part 112, the third heating part 113, the fourth heating part and the fifth heating part is connected to the first heating part 111, and the other end of the second heating part 112, the third heating part 113, the fourth heating part and the fifth heating part is electrically connected to the second heating layer 21.

[0063] Optionally, the connection between the second heating layer 21 and the third heating part 113 can be a smooth transition or a right-angle transition, corresponding to the shape of the first substrate 12.

[0064] Optionally, a first heating layer 11 is provided around the display panel 100, so that the first heating layer 11 and the second heating layer 21 can achieve a closed loop of heating layers, which can quickly heat up the display panel 100 and improve the situation of fast heat dissipation around the display panel 100.

[0065] The third heating element 113 facilitates uniform heating of the display panel 100 by the first heating layer 11, thereby increasing the heating speed of the display panel 100. Furthermore, the third heating element 113 helps prevent rapid heat dissipation from the surrounding area, resulting in better heating of the display panel 100 and enabling it to operate at low temperatures.

[0066] For reference Figure 1 In one embodiment, the array substrate 20 further includes a second substrate 22 and an array film layer 23. The second heating layer 21 is disposed on the side of the second substrate 22 facing away from the color filter substrate 10, and the array film layer 23 is disposed on the side of the second substrate 22 facing the color filter substrate 10.

[0067] The second substrate 22 can be an alkali glass substrate or an alkali-free glass substrate. Specifically, the alkali glass substrate can be sodium glass or neutral borosilicate glass, and the alkali-free glass can be alkali-free aluminum silicate glass, without limitation.

[0068] The array film layer 23 may include, but is not limited to, thin-film transistors, gates, gate insulating layers, active layers, source and drain electrodes, ohmic contact layers, passivation layers, pixel electrodes, etc. Specifically, the thin-film transistors are field-effect transistors. The gate is made of a conductive material (such as metal or transparent conductive oxide) and is used to control the switching on and off of the thin-film transistor. The gate is connected to the gate line and provides a scan signal through the gate driver. The gate insulating layer is typically made of silicon nitride (SiNx) or silicon oxide (SiO2) and is used to isolate the gate from the source and drain electrodes, prevent electrical short circuits between the gate and the source and drain electrodes, and ensure that the gate electric field can effectively control the carriers in the channel. The active layer is typically made of polycrystalline silicon or amorphous silicon. The source and drain electrodes are made of conductive material and are in contact with the active layer to form a source-drain electrode pair. The source electrode is connected to the data line to receive image signals; the drain electrode is connected to the pixel electrode to control the voltage of the liquid crystal layer 30. An ohmic contact layer is disposed between the source and drain electrodes and the active layer to reduce contact resistance and improve the performance of the thin-film transistor. A passivation layer covers the active layer and the source / drain electrodes to protect the thin-film transistor structure from external environmental influences (such as moisture and contaminants), and is typically made of silicon nitride or organic materials. The pixel electrode connects to the drain of the thin-film transistor and is used to apply voltage to the liquid crystal layer 30 to control the transmission or blocking of light.

[0069] The second heating layer 21 is disposed on the side of the second substrate 22 facing away from the color filter substrate 10, which helps to increase the contact area between the first heating layer 11 and the second heating layer 21, so that the first heating layer 11 and the second heating layer 21 can achieve a closed loop of heating layers, which is beneficial to improving the heating speed of the display panel 100.

[0070] For reference Figure 1 In one embodiment, the display panel 100 further includes a conductive element 40, which is used to electrically connect the first heating layer 11 and the second heating layer 21.

[0071] The conductive component 40 can be made of metal materials, conductive adhesives, etc., specifically aluminum and aluminum alloys, copper and copper alloys, thermoplastic conductive adhesives, thermosetting conductive adhesives, etc., without limitation.

[0072] The conductive element 40 is provided with corresponding portions that are electrically connected to the first heating layer 11 and the second heating layer 21. Specifically, the conductive element 40 is provided with corresponding portions that are connected to the second sub-heating part 1122. There may be one or more conductive elements 40, and multiple conductive elements 40 are provided at intervals, so that the first heating layer 11 and the second heating layer 21 form a heating cycle.

[0073] When the first heating layer 11 extends only on both sides of the first substrate 12 and toward the direction of the second heating layer 21, the conductive element 40 can be correspondingly configured as two elongated members and connected to the second sub-heating part 1122.

[0074] When the first heating layer 11 is disposed around the first substrate 12 and extends toward the second heating layer 21, the conductive element 40 is correspondingly configured as a closed ring or rectangular member.

[0075] For reference Figure 2 The conductive element 40 connecting the second heating part 112 and the second heating layer 21 may be the same as or different from the conductive element 40 connecting the third heating part 113 and the second heating layer 21, depending on the shape and structure of the second heating part 112 and the third heating part 113. Optionally, when the first heating layer 11 and the second heating layer 21 are spaced apart in the direction from the first substrate 12 to the second substrate 22, the conductive element 40 may also extend along the direction from the second substrate 22 to the first substrate 12. One end of the conductive element 40 is connected to the first heating layer 11, and the other end of the conductive element 40 is connected to the second heating layer 21, so that the first heating layer 11 and the second heating layer 21 are electrically connected, forming a closed circuit during the heating process. When the first heating layer 11 is not provided with the second heating part 112 and / or the third heating part 113, the conductive element 40 extends in the direction from the second substrate 22 to the first substrate 12 to connect the first heating layer 11 and the second heating layer 21.

[0076] The conductive element 40 is set to realize the electrical connection between the first heating layer 11 and the second heating layer 21, so that the first heating layer 11 and the second heating layer 21 form a closed circuit, which can quickly realize the heating of the display panel 100 and improve the problem of uneven heating.

[0077] This invention provides an electronic device, including the display panel described in any of the foregoing embodiments. The electronic device may be a mobile phone, computer, tablet, television, etc., and is not limited thereto.

[0078] For reference Figure 3 This utility model provides a method for manufacturing a display panel 100, comprising:

[0079] Step S10: Provide a color filter substrate 10, which includes a first heating layer 11.

[0080] Step S20: Provide an array substrate 20, which includes a second heating layer 21.

[0081] Step S30: The color filter substrate 10 and the array substrate 20 are arranged opposite to each other and the first heating layer 11 and the second heating layer 21 are electrically connected.

[0082] In step S30, the electrical connection between the first heating layer 11 and the second heating layer 21 can be achieved by providing a conductive element 40 on the side of the second heating layer 21 facing away from the color filter substrate 10. One end of the conductive element 40 is connected to the second heating layer 21, and the other end of the conductive element 40 is connected to the first heating layer 11. Specifically, when the conductive element 40 is conductive adhesive, conductive adhesive can be applied to the corresponding positions of the first heating layer 11 and the second heating layer 21, and the first heating layer 11 and the second heating layer 21 can be bonded together to achieve the electrical connection between the first heating layer 11 and the second heating layer 21.

[0083] The display panel 100 of this invention has a first heating layer 11 disposed in the color filter substrate 10 and a second heating layer 21 disposed in the array substrate 20. The first heating layer 11 and the second heating layer 21 are electrically connected. An externally supplied voltage realizes the heating cycle of the first heating layer 11 and the second heating layer 21. Therefore, the display panel 100 of this invention has a fast heating speed.

[0084] For reference Figure 4 In one embodiment, step S10 includes:

[0085] Step S11: Provide an initial substrate.

[0086] Step S12: A first heating layer 11 is formed on the surface of the initial substrate.

[0087] Step S13: Cut the initial substrate to form the first substrate 12 and expose the first heating layer 11.

[0088] Step S14: Bend the exposed portion of the first heating layer 11.

[0089] Optionally, step S12 further includes: polishing and coating the initial substrate; forming a flexible layer 14 on the initial substrate using a photolithography process, which can specifically include coating, development, exposure, etc., without limitation; forming a first heating layer 11 on the surface of the flexible layer 14 facing away from the initial substrate using a sputtering process, which can specifically include DC sputtering, RF sputtering, magnetron sputtering, reactive sputtering, etc., without limitation; forming an insulating layer 15 on the surface of the first heating layer 11 facing away from the flexible layer 14, which can be prepared by chemical vapor deposition; and forming a color filter layer 13 on the surface of the insulating layer 15 facing away from the flexible layer 14, which can specifically include sequentially forming a black matrix, an RGB pixel layer, and a transparent conductive layer, where the method for forming the color filter layer 13 can include coating, mask exposure, development, etc., without limitation.

[0090] Specifically, in step S13, cutting the initial substrate involves using a laser to cut at least one end of the initial substrate to expose the flexible layer 14, the first heating layer 11, and the insulating layer 15 that need to be bent, and removing the excess substrate. The cutting method can be laser cutting, specifically gas laser cutting, solid-state laser cutting, fiber laser cutting, etc., without limitation. Optionally, when cutting the initial substrate, when cutting one end of the initial substrate, the corresponding exposed portion of the first heating layer 11 is folded to form a second heating portion 112; when cutting both ends of the initial substrate, the corresponding exposed portions of the first heating layer 11 are folded to form a second heating portion 112 and a third heating portion 113; when cutting the four ends of the initial substrate, the corresponding exposed portions of the first heating layer 11 are folded to form a second heating portion 112, a third heating portion 113, a fourth heating portion, and a fifth heating portion, and the second heating portion 112, the third heating portion 113, the fourth heating portion, and the fifth heating portion are bent and surround the liquid crystal layer 30.

[0091] In one embodiment, step S13 further includes setting reference points and patterns, alignment detection, cell assembly, and bonding. Setting reference points and patterns includes setting multiple reference points and detection points on the array substrate 20 and the color filter substrate 10 respectively, and the lines connecting the reference points and detection points form a reference pattern or detection pattern on the substrate to ensure subsequent alignment accuracy. Alignment detection includes detecting whether the reference pattern on the array substrate 20 coincides with the set reference pattern; detecting whether the vertical projection of the detection pattern on the color filter substrate 10 onto the reference plane coincides with the reference pattern on the array substrate 20 to ensure that the two substrates are also aligned in the vertical direction. Cell assembly includes stacking the first substrate 12 of the color filter substrate 10 and the second substrate 22 of the array substrate 20, bonding them together with a sealing material and curing them. The sealing material can be a frame adhesive, PI (polyimide), etc., without limitation. Cell assembly also includes injecting liquid crystal molecules into the gap between the first substrate 12 and the second substrate 22 to form a liquid crystal layer 30. The curing process can be heating, pressurizing, or ultraviolet irradiation, etc., without limitation.

[0092] For reference Figure 5 In one embodiment, step S20 includes:

[0093] Step S21: Provide a second substrate 22.

[0094] In step S22, an array film layer 23 is formed on the surface of the second substrate 22 facing the color filter substrate 10.

[0095] In step S23, a second heating layer 21 is formed on the surface of the second substrate 22 facing away from the color filter substrate 10.
