Technical Field

[0001] This utility model relates to the field of display product manufacturing technology, and in particular to a display panel and display device. Background Technology

[0002] A display panel typically includes an array substrate, a color filter substrate corresponding to the array substrate, a liquid crystal layer disposed between the array substrate and the color filter substrate, and an upper polarizer disposed on the color filter substrate. Existing display panels generally have a shielding electrode layer disposed on the side of the color filter substrate facing the upper polarizer to shield the electric field generated by touching the display panel with a finger, etc., so as to avoid affecting the electric field used to drive the display in the display panel.

[0003] When external static charge is transferred to the display panel through the upper polarizer side, for example during ESD (Electro-Static Discharge) testing, the peripheral discharge of the display panel can damage the shielding electrodes, resulting in snowflake-like damage, especially for frameless products. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a display panel and a display device that solves the problem of damage to the shielding electrodes caused by static electricity.

[0005] To achieve the above objectives, the technical solution adopted in this embodiment of the utility model is: a display panel, comprising an array substrate and a color filter substrate disposed opposite to each other, and a first polarizer located on the side of the color filter substrate away from the array substrate.

[0006] The display panel also includes a shielding electrode, which is disposed between the color filter substrate and the first polarizer to shield the electric field generated when a finger touches the light-emitting surface of the display panel.

[0007] The first polarizer includes a first annular region exposed outside the shielding electrode, and the color filter substrate includes a second annular region exposed outside the shielding electrode. The orthographic projection of the second annular region onto the first polarizer is located within the first polarizer.

[0010] Optionally, the angle between the first side and the first polarizer is 30-90 degrees.

[0011] Optionally, the insulating sealant at least partially covers the first portion.

[0012] Optionally, the distance between the edge of the orthographic projection of the color filter substrate onto the first polarizer and the corresponding edge of the first polarizer is 0.3 ± 0.1 mm.

[0013] Optionally, the shielding electrode includes a second side surface, which is constructed as an inclined surface in a direction perpendicular to the first polarizer, and the second side surface is parallel to and adjacent to the first portion, and the second side surface and the first portion are formed using a synchronous process.

[0014] Optionally, in the first direction, the sum of the width of the orthographic projection of the first side on the first polarizer and the width of the orthographic projection of the first portion on the first polarizer is a first distance, the first distance being greater than or equal to 100 μm, and the first direction being the direction extending from the edge of the first polarizer toward the center of the first polarizer.

[0015] Optionally, the display panel includes a bonded side and a non-bonded side other than the bonded side, wherein on the bonded side, the first distance is greater than or equal to 100 μm, and on the non-bonded side, the first distance is greater than or equal to 300 μm.

[0016] Optionally, the first polarizer is rectangular and includes two first corners located on the bonding side and two second corners located on the non-bonding side. The first corners are chamfered right angles with a side length greater than or equal to 500 μm, and the second corners are rounded with a radius greater than or equal to 1500 μm.

[0017] Optionally, in a direction parallel to the first polarizer, the insulating sealant extends outward from the side in contact with the shielding electrode for a length greater than or equal to 0.45 mm.

[0018] This utility model embodiment also provides a display device, including the display panel described above.

[0019] The beneficial effects of this utility model are as follows: the first polarizer includes a first annular region exposed to the shielding electrode, and the color filter substrate includes a second annular region exposed to the shielding electrode. The orthographic projection of the second annular region on the first polarizer is located inside the first polarizer, that is, the shielding electrode is recessed. This increases the electrical discharge path between the first polarizer and the shielding electrode, and also increases the space for the insulating sealant, which can better seal the shielding electrode and thus prevent the shielding electrode from being damaged due to static electricity.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0031] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms “an,” “a,” or “the,” and similar terms do not indicate a quantity limitation, but rather indicate the presence of at least one. The terms “including,” “comprising,” or “containing,” and similar terms mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. The terms “connected,” “linked,” or similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms “upper,” “lower,” “left,” and “right,” etc., are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described objects changes.

[0032] The features such as "parallel," "perpendicular," and "identical" used in the embodiments of this disclosure include features in the strict sense of "parallel," "perpendicular," and "identical," as well as cases where "approximately parallel," "approximately perpendicular," and "approximately identical" include certain tolerances. Taking into account the measurement and the tolerances associated with the measurement of a specific quantity (e.g., limitations of the measurement system), they represent the acceptable deviation range for a specific value as determined by a person skilled in the art. For example, "approximately" can mean within one or more standard deviations, or within 3% or 5% of said value.

[0033] Furthermore, throughout this document, unless otherwise defined, the terms “substantially,” “essentially,” “approximately,” and “about” are used to describe and explain small variations. When used with an event or situation, these terms can cover situations where the event or situation occurs precisely or approximately. For example, when used with a numerical value, these terms can include a range of variation of the numerical value less than or equal to 10%, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. The term “substantially coplanar” can refer to two surfaces arranged along the same plane within a micrometer range, for example, within 40 μm, 30 μm, 20 μm, 10 μm, or 1 μm.

[0034] In related technologies, a liquid crystal display panel includes an array substrate and a color filter substrate disposed opposite each other, and a liquid crystal layer disposed between the array substrate and the color filter substrate. An upper polarizer is disposed on the side of the color filter substrate away from the array substrate, and a lower polarizer is disposed on the side of the array substrate away from the color filter substrate. A first electrode and a second electrode are respectively disposed on the array substrate and the color filter substrate. A voltage is applied to the first electrode and the second electrode to form an electric field for controlling the deflection of the liquid crystal in the liquid crystal layer. To prevent external electric fields from affecting the internal electric field of the display panel, a shielding electrode is disposed between the color filter substrate and the upper polarizer to shield against external electric fields.

[0035] However, in related technologies, the side of the shielding electrode and the side of the color filter substrate are flush. During electrostatic verification, due to insufficient sealing between the shielding electrode and the first polarizer, tip discharge jumps to the shielding electrode through the panel surface, causing bubbles to form at the edge of the shielding electrode, or even causing the shielding electrode to burn out, resulting in snowflake-like damage.

[0036] refer to Figure 1 and Figure 3 To address the aforementioned issues, this embodiment provides a display panel comprising an array substrate 1 and a color filter substrate 2 disposed opposite to each other, a first polarizer 3 located on the side of the color filter substrate 2 away from the array substrate 1, and a second polarizer located on the side of the array substrate 1 away from the color filter substrate 2.

[0037] The display panel also includes a shielding electrode 4, which is disposed between the color filter substrate 2 and the first polarizer 3 to shield the electric field generated when a finger touches the light-emitting surface of the display panel.

[0038] The first polarizer 3 includes a first annular region exposed to the shielding electrode 4, and the color filter substrate 2 includes a second annular region exposed to the shielding electrode 4. The orthographic projection of the second annular region onto the first polarizer 3 is located within the first polarizer 3.

[0039] The display panel also includes an insulating sealant 5 disposed in the first annular region, the insulating sealant 5 surrounding the shielding electrode 4.

[0040] In this embodiment, the shielding electrode 4 is recessed, which increases the electrical discharge path between the first polarizer 3 and the shielding electrode 4, and also increases the space for the insulating sealant 5. This allows for better sealing of the shielding electrode 4 and better isolation between the shielding electrode 4 and the first polarizer 3, thereby solving the problem of air bubbles forming at the edge of the shielding electrode 4 due to static electricity, or even damaging the shielding electrode 4 and causing snowflake-like damage.

[0041] It should be noted that, Figure 1 and Figure 2 These are all schematic diagrams of the display panel. Figure 1 and Figure 2 The diagrams only show the positional relationship of the first polarizer 3, the shielding electrode 4, and the color filter substrate 2 on one side. However, in reality, the orthographic projection of the shielding electrode 4 onto the first polarizer 3 is located within the first polarizer 3. The first polarizer 3 includes a first annular region exposed outside the shielding electrode 4, meaning the edge of the first polarizer 3 is entirely exposed outside the shielding electrode 4 along its circumferential direction. Similarly, the side surface of the color filter substrate 2 is flush with the side surface of the array substrate 1, and the orthographic projection of the color filter substrate 2 onto the first polarizer 3 is located within the first polarizer 3, meaning the edge of the first polarizer 3 is entirely exposed outside the color filter substrate 2 along its circumferential direction.

[0042] In an exemplary embodiment, the display panel includes a bonded side and a non-bonded side. For the bonded side and the non-bonded side, the indentation distance of the corresponding edges of the shielding electrode 4 may be the same or different. Generally, the edge of the shielding electrode 4 is less likely to be damaged by impact on the bonded side. Therefore, in some embodiments, the shielding electrode 4 includes a first edge located on the bonded side and a second edge located on the non-bonded side. The distance from the first edge to the corresponding edge of the first polarizer 3 is a first distance, and the distance from the second edge to the corresponding edge of the first polarizer 3 is a second distance. The first distance is less than the second distance.

[0043] In an exemplary embodiment, the color filter substrate 2 includes a first side surface. In a direction perpendicular to the first polarizer, the first side surface includes a first portion 201 configured as an inclined surface. The first portion 201 is located on the side of the color filter substrate 2 close to the first polarizer 3.

[0044] It should be noted that, in the direction perpendicular to the first polarizer 3, the length of the first part 201 can be less than or equal to the length of the color filter substrate 2. In practical applications, it can be determined based on the angle between the first part 201 and the first polarizer 3, as well as the inward distance of the side of the shielding electrode 4.

[0045] The first part 201 increases the accommodating space of the insulating sealant 5 and enhances the sealing performance of the shielding electrode 4, thereby solving the problem that the shielding electrode 4 is easily damaged by impact.

[0046] In an exemplary embodiment, the shielding electrode 4 includes a first surface and a second surface disposed opposite to each other in a direction perpendicular to the array substrate 1, and a second side surface 41 located between the first surface and the second surface. The first surface is located on the side of the shielding electrode 4 away from the color filter substrate 2. The second side surface 41 is constructed as an inclined surface, and the orthographic projection of the first surface on the first polarizer 3 is completely covered by the orthographic projection of the second surface on the first polarizer 3. The second side surface 41 and the first portion 201 are parallel and adjacent to each other, and the second side surface 41 and the first portion 201 are formed by synchronous process.

[0047] The shielding electrode 4 is generally thin, for example, 0.4 mm. If only the second side 41 of the shielding electrode 4 is constructed as a slope, the manufacturing process is difficult. To reduce the manufacturing difficulty, the first portion 201 of the first side of the color filter substrate 2 is also constructed as a slope, which simplifies the process, improves work efficiency, and facilitates the sealing of the insulating sealant 5.

[0048] With the above scheme, the second side 41 is constructed as an inclined surface, and the orthographic projection of the first surface on the first polarizer 3 is completely covered by the orthographic projection of the second surface on the first polarizer 3. That is, in the direction perpendicular to the first polarizer 3, the cross-sectional shape of the shielding electrode 4 is trapezoidal, and the area of ​​the second surface is greater than the area of ​​the second surface. This can further increase the jump distance between the first polarizer 3 and the shielding electrode 4, and further increase the space for the insulating sealant 5 to accommodate the shielding electrode 4 and the first polarizer 3.

[0049] In an exemplary embodiment, the angle θ between the second side 41 and the first polarizer is 30-90 degrees, but is not limited thereto.

[0050] In an exemplary embodiment, the display panel is rectangular in shape, the first polarizer 3 is a rectangle that conforms to the shape of the display panel, the shielding electrode 4, the array substrate 1 and the color filter substrate 2 are all constructed as rectangles that conform to the shape of the display panel, so that the second side surface 41 includes four first sub-side surfaces arranged along the circumferential direction of the shielding electrode 4, and all four first sub-side surfaces are constructed as inclined surfaces.

[0051] In an exemplary embodiment, the shielding electrode 4 is deposited in one layer on the side of the color filter substrate 2 away from the array substrate 1 using a vapor deposition process. Then, the second side surface 41 of the shielding electrode 4 and the first part 201 of the first side surface of the color filter substrate 2 are ground by an edge grinding process to simultaneously construct the second side surface 41 and the first part 201 as bevels.

[0052] In an exemplary embodiment, the insulating sealant 5 at least partially covers the first portion 201.

[0053] In an exemplary embodiment, the insulating sealant 5 is formed using a UV-curable adhesive, but this is not a limitation. After the first polarizer 3 is assembled, the insulating sealant 5 is sealed between the first polarizer 3, the shielding electrode 4, and the color filter substrate 2. That is, the insulating sealant 5 contacts the side of the first polarizer 3 closest to the color filter substrate 2, contacts the second side 41 of the shielding electrode 4, and contacts the first portion 201 of the color filter substrate 2, so as to effectively seal the shielding electrode 4.

[0054] In an exemplary embodiment, the first annular region extends outward and is exposed outside the color filter substrate 2. The orthographic projection of the color filter substrate 2 onto the first polarizer 3 is located within the first polarizer 3, and the orthographic projection of the shielding electrode 4 onto the first polarizer 3 is covered by the orthographic projection of the color filter substrate 2 onto the first polarizer 3. The distance between the edge of the orthographic projection of the color filter substrate 2 onto the first polarizer 3 and the corresponding edge of the first polarizer 3 is 0.3 ± 0.1 mm, but is not limited thereto.

[0055] In related technologies, the side surface of the first polarizer 3 is flush with the side surface of the color filter substrate 2, or the distance between the first polarizer 3 and the color filter substrate 2 is small. For example, the distance between the edge of the orthographic projection of the color filter substrate 2 onto the first polarizer 3 and the corresponding edge of the first polarizer 3 is 0.2 mm. The short-circuit distance between the first polarizer 3 and the shielding electrode 4 is small, and the space for accommodating the insulating sealant 5 is also relatively small, which can easily lead to insufficient sealing. This can easily cause a short circuit to the shielding electrode 4, potentially damaging it.

[0056] In an exemplary embodiment, in a first direction, the sum of the width of the orthographic projection of the second side 41 onto the first polarizer 3 and the width of the orthographic projection of the first portion 201 onto the first polarizer 3 is a first distance, the first distance being greater than or equal to 100 μm, and the first direction being a direction extending from the edge of the first polarizer 3 toward the center of the first polarizer 3.

[0057] In an exemplary embodiment, the display panel includes a bonded side and a non-bonded side other than the bonded side, wherein on the bonded side, the first distance a′ is greater than or equal to 100 μm, referenced. Figure 2 On the unbound side, the first distance a is greater than or equal to 300 μm, reference Figure 1 (It should be noted that when the display panel is rectangular, the bound side corresponds to one side of the rectangle, and the unbound side corresponds to the three sides of the rectangle.) Figure 1 The diagram only shows one edge that serves as the unbound side, while the other two edges that serve as the unbound side have the same structure as this edge.

[0058] refer to Figure 3 In an exemplary embodiment, the first polarizer 3 is rectangular and includes two first corners 31 located on the bonding side and two second corners 32 located on the non-bonding side. The first corners 31 are chamfered right angles with a side length greater than or equal to 500 μm, and the second corners 32 are rounded with a radius greater than or equal to 1500 μm.

[0059] It should be noted that the chamfer shape of the first corner 31 and the second corner 32 is not limited to the above description. The two first corners 31 are located on the bonding side, where electronic devices such as chips are disposed. Therefore, a protective structure is provided on the bonding side, and the chamfering process of the two first corners 31 is relatively flexible. However, the two second corners 32 are located on the non-terminal side, where no corresponding protective structure is provided. Therefore, in order to prevent sharp fragments from breaking, the two second corners 32 are rounded.

[0060] It should be noted that the chamfer shapes of the first corner 31 and the second corner 32 can be the same or different. For example, both first corners 31 can be chamfered to right angles, and both second corners 32 can also be chamfered to right angles. Alternatively, both first corners 31 and both second corners 32 can be rounded. Rounding both first corners 31 and both second corners 32 can prevent sharp fragments from breaking.

[0061] In an exemplary embodiment, in a direction parallel to the first polarizer 3, the insulating sealant 5 extends outward from the side in contact with the shielding electrode 4 with a length greater than or equal to 0.45 mm.

[0062] In an exemplary embodiment, in a direction parallel to the first polarizer 3, the width a of the second annular region exposed by the shielding electrode 4 of the color filter substrate 2 is 0.3 mm, and the width b of the third annular region exposed by the first polarizer 3 of the color filter substrate 2 is 0.3 mm. In a direction parallel to the first polarizer 3, the length of the insulating sealant 5 extending outward from the side in contact with the shielding electrode 4 can be less than or equal to the sum of the length of the second annular region and the length of the third annular region.

[0063] In some embodiments, in a direction parallel to the first polarizer 3, the length of the insulating sealant 5 extending outward from the side in contact with the shielding electrode 4 can be less than the sum of the lengths of the second annular region and the third annular region. For example, in a direction parallel to the first polarizer 3, the length of the insulating sealant 5 extending outward from the side in contact with the shielding electrode 4 is greater than or equal to 0.45 mm. This can reduce costs while meeting the sealing requirements of the shielding electrode 4, and avoid the side of the insulating sealant 5 being exposed to the first polarizer 3, thus preventing interference with other structures.

[0064] In an exemplary embodiment, a second polarizer 6 is disposed on the side of the array substrate 1 away from the color filter substrate 2.

[0065] The orthographic projection of the second polarizer 6 onto the array substrate 1 is located within the array substrate 1, and the distance c between the edge of the second polarizer 6 and the corresponding edge of the array substrate 1 is 0.5cm. That is, the second polarizer 6 is recessed relative to the array substrate 1 to avoid interference with other structures.

[0066] This utility model embodiment also provides a display device, including the display panel described above.

[0067] The display panel includes a color filter substrate 2 and an array substrate 1. The color filter substrate 2 includes a first substrate, a black matrix disposed on the first substrate, and a filter film of at least one color. The array substrate 1 and the color filter substrate 2 are arranged in a cell.

[0068] The black matrix is ​​spaced apart from the filter film. Optionally, the color filter substrate includes three color filter films: a red filter film, a green filter film, and a blue filter film. A liquid crystal layer is disposed between the array substrate and the color filter substrate. The liquid crystal layer includes multiple liquid crystal units, each corresponding to a color filter film. Multiple pixel driving electrodes are disposed on the array substrate, corresponding to the multiple liquid crystal units. Each pixel electrode drives one liquid crystal unit to deflect, and after being acted upon by the corresponding filter film, it emits light of the corresponding color.

[0069] The display device includes, but is not limited to, components such as: a radio frequency unit, a network module, an audio output unit, an input unit, a sensor, a display unit, a user input unit, an interface unit, a memory, a processor, and a power supply. Those skilled in the art will understand that the above-described structure of the display device does not constitute a limitation on the display device; the display device may include more or fewer of the aforementioned components, or combine certain components, or arrange different components. In embodiments of this utility model, the display device includes, but is not limited to, a monitor, a mobile phone, a tablet computer, a television set, a wearable electronic device, and a navigation display device.

[0070] The display device can be: LCD TV, LCD monitor, digital photo frame, mobile phone, tablet computer, etc., wherein the display device further includes flexible circuit board, printed circuit board and back plate.
