[0048] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.
[0049] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0050] When the display panel is used in a vehicle, it needs to meet the requirements of normal display while achieving anti-peeping and suppressing light pollution to prevent the driver from being distracted. When used for in-vehicle co-pilot display, it needs to be all-round anti-peeping and suppress light pollution. The current display panels use left and right anti-peeping viewing angles, and there is no anti-peeping setting for the upper side. There may be a hidden danger of being peeped at from the upper side of the display panel.
[0051] For this purpose, the applicant analyzes the existing display panels. Figure 1 As shown, each light-emitting unit 10 includes a red pixel 10a, a green pixel 10b and a blue pixel 10c. If it is to realize dynamic privacy protection, the red pixel 10a, the green pixel 10b and the blue pixel 10c need to be divided respectively (for example, part of the red pixel 10a is used for privacy protection and part is used for sharing). Figure 2a), one of the two sub-pixels is set with an anti-peeping light path, the sub-pixel corresponding to the anti-peeping light path is lit in the anti-peeping mode, and the sub-pixel corresponding to the non-anti-peeping light path is lit in the sharing mode, so as to realize dynamic anti-peeping based on demand. The light path is as follows Figure 2b As shown (area a is lit in anti-peeping mode, and area b is lit in sharing mode). This structure can only realize left and right anti-peeping. In addition, the cutting area of the pixel definition layer used to define the pixels in this structure is large, which damages the aperture ratio (affecting the display brightness). At the same time, in this pixel structure, if the shielding part (BM glue) 11 of the anti-peeping light path is set at the same height, it will cause serious visual color deviation and low display quality.
[0052] Based on this discovery, the applicant has improved the structure of the pixels of the existing display panel, which not only realizes dynamic anti-peeping, but also realizes anti-peeping in three directions of the display panel (e.g., the left side, right side and top side of the display panel), and has no color deviation within the set viewing angle range, thereby improving the user experience.
[0053] Next, the display panel and the display device proposed in the present application are described with reference to the accompanying drawings.
[0054] like Figure 3 FIG. 4 is a schematic diagram of a display panel according to an embodiment of the present application.
[0055] The display panel 100 includes a display area 110 (also called AA area) and a non-display area 120 at least partially surrounding one side of the outer periphery of the display area 110. The non-display area 120 is provided with a bending area and a binding area (not shown), the binding area is used to carry a binding component in a subsequent process, and a portion of the non-display area 120 is bent to the back of the display area 110 through the bending area.
[0056] The display area 110 includes light-emitting units 111 arranged in an array, and each light-emitting unit 111 includes a plurality of pixels, such as red pixels, green pixels and blue pixels. In the present embodiment, the red pixels, green pixels and blue pixels are designed side by side, and the red pixel includes a first sub-red pixel and a second sub-red pixel, the green pixel includes a first green-red pixel and a second sub-green pixel, and the blue pixel includes a first sub-blue pixel and a second sub-blue pixel. Each pixel includes a first sub-pixel and a second sub-pixel. The first sub-pixel and the second sub-pixel respectively have an anode, and the two anodes are not connected. The anodes are respectively electrically connected to the pixel driving circuit (that is, the same pixel driving circuit can drive one sub-pixel or two sub-pixels of two sub-pixels of the same color). The first sub-pixel is an anti-peeping pixel, and the second sub-pixel is a shared pixel.
[0057] like Figure 4 FIG. 1 is a schematic cross-sectional view of a display panel according to an embodiment of the present application, wherein the display panel includes:
[0058] Substrate 130: The substrate 130 covers the display area and the non-display area. It is a flexible substrate. Its material can be selected from polyimide (PI), polyethylene naphthalate (PEN) or polyethylene terephthalate (PET), etc. The material can also be a mixed material of the above materials, or the substrate 130 can be a hard substrate, such as glass. The substrate 130 has a driving layer, which includes a driving circuit and a variety of signal lines.
[0059] The light-emitting functional layer 140 is disposed on one side of the substrate 130, and the light-emitting functional layer includes a plurality of light-emitting units 111. Each light-emitting unit includes pixels of a preset pattern (such as pixels arranged side by side), and pixels of the same color include a first sub-pixel and a second sub-pixel, and the first sub-pixel is adjacent to the second sub-pixel with a gap therebetween (the first sub-pixel and the second sub-pixel can be defined by pixel defining layers, respectively, and each of them has an anode, and the anode of the first sub-pixel is isolated / not electrically connected to the anode of the second sub-pixel, and the anode is electrically connected to the pixel driving circuit respectively).
[0060] The encapsulation layer 150 is disposed on a side of the light-emitting functional layer 140 away from the substrate 130 .
[0061] The light-shielding functional layer 160 is disposed on a side of the encapsulation layer 150 away from the light-emitting functional layer 140. The light-shielding functional layer 160 includes a shielding portion (also referred to as a shielding portion). The shielding portion is configured such that its positive projection on the light-emitting unit surrounds the area of the first sub-pixel other than the side opposite to the second sub-pixel (surrounds the three sides of the first sub-pixel other than the side opposite to the second sub-pixel). The viewing angle can be limited by the shielding portion, and anti-peeping is achieved in three directions of the display panel (e.g., the left side, the right side, and the upper side of the display panel), and there is no color deviation within the set viewing angle range, thereby improving the user experience. Preferably, the light-shielding functional layer includes an optical glue (e.g., an OC glue), and the optical glue covers the shielding portion.
[0062] Next, combine Figure 5 And refer to Figure 4 To describe the pixel structure of the light-emitting unit.
[0063] Figure 5 A top view schematically depicts the arrangement of pixels in a light-emitting unit.
[0064] The pixels in the light-emitting unit 111 are arranged in a strip shape extending along the second direction, and the red pixel 111a, the green pixel 111b and the blue pixel 111c are arranged side by side (along the first direction), and the pixels in the light-emitting unit 111 are staggered along the second direction (i.e., pixels of the same color are in different columns). In this embodiment, the widths of the red pixel 111a, the green pixel 111b and the blue pixel 111c are different (along the first direction), and the lengths may be the same (along the second direction), the width of the blue pixel 111c is greater than the width of the green pixel 111b, and the width of the green pixel 111b is greater than the width of the red pixel 111a. In other embodiments, the widths of the red pixel 111a, the green pixel 111b and the blue pixel 111c may be the same, and their lengths (along the second direction) may be the same. The first direction and the second direction intersect, the second direction is the length direction of the display panel, and the first direction is the width direction of the display panel.
[0065] The following description takes the red pixel 111a as an example, and its length L1 (width) along the first direction (x direction) is less than the length L2 along the second direction (y direction). The length L2 can be the sum of the lengths of the first sub-red pixel and the second sub-red pixel along the second direction (or including the gap therebetween). Preferably, the ratio of the length L2 in the second direction to the length L1 in the first direction is greater than 3, and preferably, the ratio is between 3-10. With such a design, when anti-peeping settings are required, the distance required to be divided in the second direction is very small. The pixels are set to be strips extending in the second direction, and after the division, the two sides (x direction) of the pixels (shared pixels) in the shared mode have no BM blocking them, so that the left and right sides are not protected from peeping. At the same time, because the length in the second direction is longer, the blocking parts / light-shielding parts (such as BM glue) on both sides (y direction) of the pixel will not affect the sub-pixels (shared pixels) used for sharing. Under this structure, the aperture ratio loss of the pixel definition layer (PDL) is minimal, which can meet the occasions with high display quality requirements.
[0066] In one embodiment, see Figure 5 The red pixel 111a includes a first sub-red pixel 111a1 and a second sub-red pixel 111a2 along the second direction, the length L21 of the first sub-red pixel 111a1, the length L22 of the second sub-red pixel 111a2, and the ratio of the length L22 of the second sub-red pixel 111a2 to the length L21 of the first sub-red pixel 111a1 is greater than or equal to 2, such as the ratio is between 2 and 10. With such a design, the first sub-red pixel 111a1 (also called anti-peeping pixel) used for the red pixel 111a is smaller, which can match the lower shielding portion 161 (BM glue) (in the z direction), and can reduce color deviation.
[0067] In one embodiment, see Figure 5The green pixel 111b includes a first green sub-pixel 111b1 and a second green sub-pixel 111b2 along the second direction (y direction), and the blue pixel 111c includes a first blue pixel 111c1 and a second blue pixel 111c2 along the second direction (y direction). For pixels arranged along the first direction, all pixels are close to horizontal in the horizontal direction (in the first direction). The shielding portion (BM glue) 161 includes a first shielding portion 1611 surrounding at least part of the first red sub-pixel, a second shielding portion 1612 surrounding at least part of the first green sub-pixel, and a third shielding portion 1613 surrounding at least part of the first blue sub-pixel. Preferably, the first shielding portion, the second shielding portion and the third shielding portion are an integral structure. At least part of the first shielding portion, the second shielding portion and the third shielding portion are m-shaped or cap-shaped. In this way, anti-peeping in three directions is achieved (anti-peeping on the left, right and upper sides of the display panel). All pixels are close to horizontal in the horizontal direction, and the size of the pixels used for privacy protection (such as the area of the pixels) is the same or similar (similar means that the area ratio is within the range of 10%), and the shielding part (BM glue) thereon has a similar degree of influence on the privacy protection pixels used for privacy protection (the first red sub-pixel, the first green sub-pixel and the first blue sub-pixel are collectively referred to as privacy protection pixels, and their areas are equivalent. The brightness attenuation is affected by the similar degree, thereby improving the color deviation within the viewing angle range and improving the display quality. The first sub-pixel is defined by the first pixel defining opening, and the first pixel defining opening is matched and defined with the first anode, and the second sub-pixel is defined by the second pixel defining opening, and the second pixel defining opening is matched and defined with the second anode, and the first anode is not electrically connected to the second anode.
[0068] As Figure 5 Variations of the embodiments, such as Figure 6 FIG. 1 is a schematic diagram of pixel arrangement of another embodiment. Figure 5The difference between the embodiments is that the shielding portion 161 has a protrusion 161a along the second direction, and the projection of the protrusion 161a on the light-emitting unit blocks part of the first blue sub-pixel 111c1, that is, it divides the first blue sub-pixel 111c1 into two areas, the first area 111c11 and the second area 111c12 (dividing the first blue sub-pixel into two anti-peeping pixels). In this way, the sizes of the anti-peeping pixels used for anti-peeping are similar (similar can be understood as the difference between them is within the threshold range, such as 2%, 3%, 5%, 8%, 10%, etc.), and the shielding portion 161 (BM glue) thereon has a similar degree of influence on the brightness attenuation of the sub-pixels used for anti-peeping (the first red sub-pixel, the first green sub-pixel and the first blue sub-pixel), thereby improving the color deviation within the viewing angle range and improving the display quality. In this embodiment, in the same light-emitting unit, the protrusion is used to divide the first blue sub-pixel into two (same or similar areas) anti-peeping pixels, and in other embodiments, the protrusion is used to divide the first blue sub-pixel into two (same or similar areas) anti-peeping pixels. The blue sub-pixel is divided into multiple (such as 3, 4 or more) anti-peeping pixels of the same or similar area, that is, the ratio of the number of first sub-pixels of the same color to the number of second sub-pixels in the same light-emitting unit is greater than or equal to 2 (such as 2, 3, 4). Preferably, in the same light-emitting unit, the areas of the anti-peeping pixels after being divided by the raised portion (the first red sub-pixel, the first green sub-pixel or the first blue sub-pixel) are the same or similar, which can improve the color deviation within the viewing angle range and improve the display quality. Similar areas can be understood as the area difference between the two areas is within a threshold range, such as 2%, 3%, 5%, 8%, 10%, etc.
[0069] As Figure 5 Variations of the embodiments, such as Figure 7 FIG. 4 is a schematic diagram showing the arrangement of pixels according to another embodiment.
[0070] The light-emitting unit includes red pixels, green pixels and blue pixels in strips extending along the second direction. The red pixels and green pixels are arranged along the second direction (y direction) and arranged side by side with the blue pixels. The red pixel includes a first red sub-pixel 20a1 and a second red sub-pixel 20a2 extending along the second direction, the green pixel includes a first green sub-pixel 20b1 and a second green sub-pixel 20b2 extending along the second direction, and the blue pixel includes a first blue sub-pixel 20c1 and a second blue sub-pixel 20c2 extending along the second direction. The shielding portion 24 is projected on the light-emitting unit to surround at least a portion of the first red sub-pixel 20a1, the first green sub-pixel 20b1 and the first blue sub-pixel 20c1. The shielding portion 24 has a protrusion 24a extending along the second direction, the protrusion 24a divides the first red sub-pixel 20a1 into two areas, namely, areas 20a11 / 20a12 (also called anti-peeping pixels), the protrusion 24b divides the first green sub-pixel 20b1 into two areas, namely, areas 20b11 / 20b12 (also called anti-peeping pixels), and the protrusion 24c divides the first blue sub-pixel 20c1 into two areas, namely, areas 20c11 / 20c12 (also called anti-peeping pixels). In this way, the sub-pixels used for anti-peeping (anti-peeping pixels) are similar in size, and the shielding portion 24 (BM glue) thereon has a similar degree of influence on the brightness attenuation of the sub-pixels used for anti-peeping, thereby improving the color deviation within the visible viewing angle range and improving the display quality. The first red sub-pixel, the first green sub-pixel, and the first blue sub-pixel (and the areas blocked and divided by the raised portion) are collectively referred to as anti-peeping pixels, and the second red sub-pixel, the second green sub-pixel, and the second blue sub-pixel are collectively referred to as shared pixels. In the same light-emitting unit, the anti-peeping pixels (the first red sub-pixel, the first green sub-pixel, and the first blue sub-pixel) and shared pixels (the second red sub-pixel, the second green sub-pixel, and the second blue sub-pixel) of the same color are arranged along the second direction, there is a gap between the anti-peeping pixels and the shared pixels, the anti-peeping pixels are adjacent to the shared pixels, and the length of the shared pixels in the second direction is greater than the length of the anti-peeping pixels.
[0071] Based on the same inventive concept, the embodiment of the present application further provides a display device, which includes the display panel provided in the embodiment of the present application. The display device can be used in smart devices (such as portable computers, and can also be used in smart cars as a vehicle-mounted display (which can suppress light pollution while meeting the anti-peeping function to prevent the driver from being distracted).
