[0002] To meet consumers' increasingly demanding visual needs, display products are developing towards higher resolution and higher definition, meaning that the size of pixel units is getting smaller and smaller.

[0035] This application is described in detail below. Examples of embodiments of this application are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. Furthermore, detailed descriptions of known technologies that are unnecessary for the features of this application are omitted. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0036] It will be understood by those skilled in the art that, unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0037] Those skilled in the art will understand that, unless specifically stated otherwise, the singular forms “a,” “an,” “the,” and “the” used herein may also include the plural forms. It should be further understood that the term “comprising” as used in the specification of this application means the presence of the stated features and / or components, but does not exclude the presence or addition of one or more other features, components, and / or groups thereof. The term “and / or” as used herein includes all or any units and all combinations of one or more associated listed items.

[0038] First, let's introduce and explain several terms used in this application:

[0039] Color resist: refers to a light-transmitting medium that allows light of a specified wavelength (i.e., a specified color) to pass through while blocking light of other wavelengths (i.e., other colors) from passing through. Specifically, a color resist that allows green light to pass through is called a green color resist, a color resist that allows red light to pass through is called a red color resist, a color resist that allows blue light to pass through is called a blue color resist, and so on.

[0040] The inventors of this application discovered through research that excessively small pixel unit size can cause color separation, reducing display quality. The main cause of this color separation is the diffraction of light passing through or emitted by the pixel unit due to its small size.

[0041] It should be noted that the dimensions described in this application (including the dimensions of pixels, the dimensions of color resist holes, etc.) all refer to the diagonal distance.

[0042] The filter unit, color filter structure, display panel, and display device provided in this application are intended to solve the above-mentioned technical problems of the prior art.

[0043] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments.

[0044] This application provides a filter unit 100, the structural schematic diagram of which is shown below. Figures 1-6 As shown, the filter unit 100 has a color blocking aperture 101, and the minimum distance from at least a portion of the opening edge of the color blocking aperture 101 to the opening geometric center of the color blocking aperture 101 is equal.

[0045] In this embodiment, the color filter hole 101 of the filter unit 100 adopts a structure in which at least part of the opening edge is equidistant from the geometric center of the opening, so as to minimize the difference in the distance between the opening edge and the geometric center of the opening of the color filter hole 101. This can reduce the probability or degree of diffraction of light passing through a single color filter hole 101, which is beneficial to reduce the degree of color separation and improve display quality.

[0046] In some possible implementations, such as Figure 1 , Figure 4 and Figure 5 As shown, the opening of the color blocking hole 101 is a regular polygon, and at least part of the apex corners of the regular polygon have rounded chamfers 102.

[0047] In this embodiment, the opening of the color blocking hole 101 is a regular polygon, which makes the distance from the opening edge to the geometric center of the opening of the color blocking hole 101 more uniform and the distance from the opening edge to the geometric center of the opening of the color blocking hole 101 more likely to be equal.

[0048] The regular polygon has rounded chamfers 102 at at least some of its vertices, which can make the distance change from the edge of the opening vertices of the color blocking aperture 101 to the geometric center of the opening more gradual. This helps to reduce the difference in distance between the opening edge and the geometric center of the opening of the color blocking aperture 101, thereby reducing the probability or degree of diffraction of light passing through a single color blocking aperture 101 and reducing the degree of color separation.

[0049] Specifically, regular polygons can include squares, regular pentagons, regular hexagons, regular heptagons, regular octagons, and so on.

[0050] In some possible implementations, such as Figure 4 As shown, at least some of the edges of the regular polygon are arcs 103. Optionally, the projection of the center of the arc 103 onto the plane containing the opening lies within the opening.

[0051] In this embodiment, the edge of the polygonal opening of the color blocking aperture 101 is improved. Specifically, in a plane perpendicular to the axis of the color blocking aperture 101, the edge of the polygonal opening of the color blocking aperture 101 is made into an arc 103. This makes it easier for the distances from each part of the arc 103 edge of the polygon to the geometric center of the opening to be equal, which helps to reduce the probability or degree of diffraction of light passing through a single color blocking aperture 101, and reduce the degree of color separation. Specifically, when each edge of the polygon is an arc 103, the opening of the color blocking aperture 101 forms a flower shape.

[0052] In some possible implementations, such as Figure 6 As shown, the opening of the color resist hole 101 is circular.

[0053] In this embodiment, a circular opening structure is adopted, so that the distance from all opening edges of the color resist hole 101 to the geometric center of the opening is equal. This can best eliminate the long and short sides of the opening of the color resist hole 101, and can better reduce the probability or degree of diffraction of light passing through a single color resist hole 101. This is beneficial to reduce the degree of color separation and improve display quality.

[0054] In some possible implementations, such as Figure 3 As shown, the intersection of the wall of the color blocking hole 101 at least at the opening and the axial section of the color blocking hole 101 is curve 104.

[0055] In this embodiment, the opening edge of the color resist aperture 101 is rounded. Specifically, at least the opening of the color resist aperture 101 is rounded in a direction parallel to the axis of the color resist aperture 101. That is, at least the opening of the color resist aperture 101 adopts a flared structure, which can increase the opening size of the color resist aperture 101. This helps to reduce the probability or degree of diffraction of light passing through a single color resist aperture 101, which helps to reduce the degree of color separation and improves display quality.

[0056] Based on the same inventive concept, this application provides a color filter structure 400, the structural schematic diagram of which is shown below. Figures 7-10 As shown, it includes: a first color filter 210, a second color filter 220, a third color filter 230, and at least three filter units 100 arranged in an array as provided in the above embodiments.

[0057] At least three filter units 100 include a first filter unit 110, a second filter unit 120 and a third filter unit 130, which respectively house a first color resist 210, a second color resist 220 and a third color resist 230.

[0058] The size of the color blocking aperture 101 of the first filter unit 110 is smaller than the size of the color blocking aperture 101 of the second filter unit 120, and the size of the color blocking aperture 101 of the first filter unit 110 is smaller than the size of the color blocking aperture 101 of the third filter unit 130.

[0059] In this embodiment, the color filter structure 400 adopts a structure including at least three of the aforementioned filter units 100, each accommodating different color resists, and the size of the color resist aperture 101 of one filter unit 100 is smaller than the size of the color resist aperture 101 of the other two filter units 100. This can effectively reduce the degree of color separation and is beneficial to improving display quality.

[0060] It is understandable that light can be filtered by the color resist in the light filtering unit 100 to display a pixel of a specified color, and the size of the color resist aperture 101 of the light filtering unit 100 can limit the size of the pixel of that color.

[0061] Optionally, the first color resist 210 is a green color resist and is housed in the first filter unit 110; the second color resist 220 is one of a red color resist and a blue color resist and is housed in the second filter unit 120; and the third color resist 230 is the other of a red color resist and a blue color resist and is housed in the third filter unit 130. The size of the color resist aperture 101 in the first filter unit 110 is smaller than the size of the color resist aperture 101 in the second filter unit 120 and the third filter unit 130. This allows the size of the green pixel to be smaller than the size of the red pixel, and the size of the green pixel to be smaller than the size of the blue pixel. This effectively reduces the degree of color separation and helps improve display quality.

[0062] In some possible implementations, such as Figures 7-10 As shown, the size of the color resist aperture 101 of the second filter unit 120 is smaller than the size of the color resist aperture 101 of the third filter unit 130; the first color resist 210 in the first filter unit 110 is a green color resist, the second color resist 220 in the second filter unit 120 is a red color resist, and the third color resist 230 in the third filter unit 130 is a blue color resist.

[0063] Based on the aforementioned embodiments, this embodiment further defines the size relationship between the color resist aperture 101 of the second filter unit 120 and the size of the color resist aperture 101 of the third filter unit 130. This ensures that when the first color resist 210 is green, the second color resist 220 is red, and the third color resist 230 is blue, the size of the green pixel is the smallest, and the size of the blue pixel is the largest. This enhances the reduction of color separation, thus improving display quality.

[0064] Optionally, the ratio of the size of the color blocking aperture 101 of the first filter unit 110, the size of the color blocking aperture 101 of the second filter unit 120, and the size of the color blocking aperture 101 of the third filter unit 130 is 43:55:63.

[0065] In this embodiment, the dimensions of the color blocking apertures 101 in the first filter unit 110, the second filter unit 120 and the third filter unit 130 are 43:55:63, so that the pixel size ratio of the light after being filtered by the color blocking apertures in the filter unit 100 to present the specified color is 43:55:63.

[0066] Specifically, the ratio of the size of the green pixel, the size of the red pixel, and the size of the blue pixel can be 43:55:63, which can enhance the reduction of color separation. In addition, by adjusting the light transmittance at the blue color resist (i.e., blue light luminous efficiency), the reduction of color separation can be further enhanced, thereby improving the display quality.

[0067] Optionally, the size of the color blocking aperture 101 of the first filter unit 110 is not less than 365.5 micrometers and not more than 494.5 micrometers; the size of the color blocking aperture 101 of the second filter unit 120 is not less than 467.5 micrometers and not more than 632.5 micrometers; and the size of the color blocking aperture 101 of the third filter unit 130 is not less than 535.5 micrometers and not more than 724.5 micrometers.

[0068] In this embodiment, the size of each color blocking aperture 101 in the first filter unit 110, the second filter unit 120 and the third filter unit 130 adopts a specific value within the corresponding range, so that the pixel size that presents the specified color after the light is filtered by the color blocking aperture in the filter unit 100 presents a specific value within the corresponding range.

[0069] Specifically, the size of green pixels can be no less than 365.5 micrometers and no more than 494.5 micrometers; the size of red pixels can be no less than 467.5 micrometers and no more than 632.5 micrometers; and the size of blue pixels can be no less than 535.5 micrometers and no more than 724.5 micrometers. This can enhance the reduction of color separation. Similarly, by adjusting the light transmittance at the blue color resist (i.e., blue light luminous efficiency), the reduction of color separation can be further enhanced, thereby improving display quality.

[0070] In some possible implementations, such as Figures 7-10 As shown, the third filter unit 130 is located between the first filter unit 110 and the second filter unit 120.

[0071] In this embodiment, the positions of the first filter unit 110, the second filter unit 120, and the third filter unit 130 are specifically defined, that is, the positions of the first color resist 210, the second color resist 220, and the third color resist 230 are specifically defined, thereby enhancing the degree of color separation reduction and improving display quality.

[0072] Specifically, the blue resist can be positioned between the green and red resists. That is, the blue pixel is located between the green and red pixels.

[0073] In some possible implementations, such as Figure 11 As shown, any third filter unit 130 is adjacent to at least two first filter units 110, and any third filter unit 130 is adjacent to at least one second filter unit 120.

[0074] In this embodiment, the number of each filter unit in the filter unit group composed of the first filter unit 110, the second filter unit 120 and the third filter unit 130 is specifically limited, that is, the number of the first color resist 210, the second color resist 220 and the third color resist 230 is specifically limited, thereby enhancing the degree of color separation reduction and improving display quality.

[0075] Specifically, any blue color filter can be adjacent to at least two green color filters, and at the same time, any blue color filter can be adjacent to at least one red color filter. That is, a pixel unit group consists of one blue pixel, two green pixels, and one red pixel.

[0076] The inventors of this application have considered that the sharpness of the boundaries between different pixels affects the degree of color separation. Therefore, this application provides the following possible implementation of the color filter structure 400:

[0077] like Figures 7-10 As shown, the color filter structure 400 in this embodiment of the application further includes a black matrix 300.

[0078] like Figure 7 and Figure 8 As shown, the black matrix 300 is fitted between the color blocking apertures 101 of two adjacent filter units 100 in at least three filter units 100.

[0079] In this embodiment, the black matrix 300 can absorb light. By setting the black matrix 300 between each adjacent filter unit 100, especially between the color blocking apertures 101 of each adjacent filter unit 100, the boundary of the color blocking apertures 101 (i.e. the boundary of the pixels) can be clearly defined. This is beneficial to reduce color crosstalk and color separation, and can improve display quality.

[0080] Optionally, a black matrix 300 can be set in the position where there are no pixels to absorb the excess light in the non-pixel area, thereby achieving the purpose of eliminating impurity light.

[0081] Optionally, such as Figure 9 and Figure 10 As shown, any filter unit 100 can be mainly composed of a black matrix 300. The holes (e.g., through holes or deep holes) in the black matrix 300 are color resist holes 101, which can be used to accommodate the corresponding color resist.

[0082] Optionally, the color filter structure 400 may include a black matrix 300 and various color resists. The holes (e.g., through holes or deep holes) distributed in an array on the black matrix 300 are color resist holes 101, which can be used to accommodate the corresponding color resists.

[0083] Based on the same inventive concept, this application provides a display panel, which includes: a backlight assembly (not shown in the figure) and any of the color filter structures 400 provided in the above embodiments.

[0084] One side of the backlight assembly is attached to one side of the color filter structure 400.

[0085] In this embodiment, the backlight assembly provides backlight for the display panel. After the backlight is filtered by the color filter structure 400 provided in the aforementioned embodiments, various pixels are formed as required, and finally an image is formed.

[0086] Optionally, the backlight assembly may include a substrate layer, a cathode layer, an electron transport layer, a light-emitting layer, a hole transport layer, and an anode layer, etc., to form a backlight structure such as LED (light-emitting diode), Micro-LED (micro-light-emitting diode), or OLED (Organic Light-Emitting Diode).

[0087] Optionally, the backlight assembly may include a backlight layer, an array substrate, and a liquid crystal encapsulation layer, etc., to form an LCD (Liquid Crystal Display) backlight structure.

[0088] In this embodiment, since the display device adopts any of the color filter structures 400 provided in the foregoing embodiments, the principle and technical effects are described in the foregoing embodiments and will not be repeated here.

[0089] Based on the same inventive concept, the present application provides a display device including: any of the filter units 100 provided in the above embodiments;

[0090] Alternatively, it may include: any of the color filter structures 400 provided in the above embodiments;

[0091] Alternatively, it may include any of the display panels provided in the above embodiments.

[0092] In this embodiment, since the display device adopts any of the filter units 100, color filter structures 400, or display panels provided in the foregoing embodiments, the principles and technical effects are described in the foregoing embodiments and will not be repeated here.

[0093] By applying the embodiments of this application, at least the following beneficial effects can be achieved:

[0094] 1. The color filter unit 100 adopts a structure in which at least part of the opening edge is equidistant from the geometric center of the opening, so as to minimize the difference in the distance between the opening edge and the geometric center of the opening of the color filter unit 101. This can reduce the probability or degree of diffraction of light passing through a single color filter unit 101, which is beneficial to reduce the degree of color separation and improve display quality.

[0095] 2. The opening of the color blocking aperture 101 is a regular polygon, which makes the distance distribution from the edge of the opening to the geometric center of the opening more uniform, and the distances from the edge of the opening to the geometric center of the opening are more likely to be equal. Furthermore, at least some of the apex corners of the regular polygon have rounded chamfers 102, which makes the distance change from the edge of the apex corner of the opening to the geometric center of the opening more gradual, which helps to reduce the difference in distances from the edge of the opening to the geometric center of the opening, thereby reducing the probability or degree of diffraction of light passing through a single color blocking aperture 101 and reducing the degree of color separation.

[0096] 3. The edge of the polygonal opening of the color blocking aperture 101 has been improved. Specifically, in the plane perpendicular to the axis of the color blocking aperture 101, the edge of the polygonal opening of the color blocking aperture 101 is made into an arc 103. This makes it easier for the distances from each part of the arc 103 edge of the polygon to the geometric center of the opening to be equal. This can help reduce the probability or degree of diffraction of light passing through a single color blocking aperture 101 and reduce the degree of color separation.

[0097] 4. The circular opening structure ensures that the distance from all opening edges of the color resist aperture 101 to the geometric center of the opening is equal. This effectively eliminates the long and short sides of the opening of the color resist aperture 101, thereby reducing the probability or degree of diffraction of light passing through a single color resist aperture 101. This helps to reduce the degree of color separation and improves display quality.

[0098] 5. The opening edge of the color resist aperture 101 is rounded. Specifically, at least the opening of the color resist aperture 101 is rounded in a direction parallel to the axis of the color resist aperture 101. That is, at least the opening of the color resist aperture 101 adopts a flared structure, which can increase the opening size of the color resist aperture 101, thereby reducing the probability or degree of diffraction of light passing through a single color resist aperture 101, reducing the degree of color separation, and improving display quality.

[0099] 6. The color filter structure 400 adopts a structure including at least three of the aforementioned filter units 100, each accommodating different color resists, and the size of the color resist aperture 101 of one filter unit 100 is smaller than the size of the color resist aperture 101 of the other two filter units 100. This can effectively reduce the degree of color separation and is beneficial to improving display quality.

[0100] 7. The size relationship between the color resist aperture 101 of the second filter unit 120 and the size of the color resist aperture 101 of the third filter unit 130 is further defined. This ensures that when the first color resist 210 is green, the second color resist 220 is red, and the third color resist 230 is blue, the size of the green pixel is the smallest, and the size of the blue pixel is the largest. This enhances the reduction of color separation and improves display quality.

[0101] 8. The third filter unit 130 is located between the first filter unit 110 and the second filter unit 120, that is, the positions of the first color resist 210, the second color resist 220 and the third color resist 230 are specifically defined, thereby enhancing the degree of color separation reduction and improving display quality.

[0102] 9. Any third filter unit 130 is adjacent to at least two first filter units 110, and any third filter unit 130 is adjacent to at least one second filter unit 120. That is, the number of first color resist 210, second color resist 220 and third color resist 230 is specifically limited, thereby enhancing the degree of color separation reduction and improving display quality.

[0103] 10. The black matrix 300 can absorb light. By setting the black matrix 300 between each adjacent filter unit 100, especially between the color blocking apertures 101 of each adjacent filter unit 100, the boundary of the color blocking apertures 101 (i.e. the boundary of the pixels) can be clearly defined. This helps to reduce color crosstalk and the degree of color separation, and can improve display quality.
