Detailed Description
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein may be combined with other embodiments.
It should be understood that the preferred embodiments described below are only for illustrating and explaining the present invention and are not to be used for limiting the present invention. And the embodiments and features of the embodiments in the present application may be combined with each other without conflict. Also, the shapes and sizes of the various elements in the drawings are not to scale and are merely intended to illustrate the present invention.
In order to better understand the technical solutions of the present invention, the technical solutions of the present invention are described in detail below with reference to the drawings and the specific embodiments, and it should be understood that the specific features in the embodiments and the embodiments of the present invention are detailed descriptions of the technical solutions of the present invention, and are not limitations of the technical solutions of the present invention, and the technical features in the embodiments and the embodiments of the present invention may be combined with each other without conflict.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic view illustrating a display panel in a bent state according to an embodiment of the present invention; FIG. 2 is a schematic diagram of the display panel of FIG. 1 in a planar state; fig. 3 is a partial structure diagram of the region Q1 in fig. 2. Referring to fig. 1 to 3, the display panel includes a substrate base (not shown in fig. 1 to 3); the display area AA comprises a main display area A0 and an auxiliary display area FA, and a substrate positioned in the auxiliary display area FA can be bent relative to a substrate positioned in the main display area A0; the display area AA includes a plurality of pixel units 10 arranged in a first direction X and a second direction Y, wherein the first direction X and the second direction Y intersect; the auxiliary display area FA includes a first auxiliary display area FA1, the first auxiliary display area FA1 being located at one side of the main display area a0 in the first direction X; the opening area of at least one pixel cell 10 located at the main display area a0 is greater than that of the pixel cell 10 of the first auxiliary display area FA 1.
In general, a conventional curved display panel is manufactured in a planar state, and then the planar display panel is bent to form a display panel in a bent state (i.e., a curved state, which is an operating state). Therefore, it can be understood that, for a display panel in a planar state (i.e., a display panel before being bent), the first direction X and the second direction Y are two directions intersecting in the same plane; for a curved display panel (i.e., a display panel after bending), the first direction X and the second direction Y are two directions intersecting in space. The display panel typically further includes a non-display area BA surrounding the display area AA. Moreover, the substrate of the curved display panel can be made of flexible materials, so that the display panel has good flexibility.
Further, the base substrate located in the auxiliary display area FA can be bent with respect to the base substrate of the main display area a0, that is, the side of the base substrate located in the auxiliary display area FA away from the main display area a0 is bent toward the backlight side of the base substrate of the main display area a0 (i.e., the side where the pixel unit 10 is not provided).
Fig. 3 only shows 3 rows × 4 columns of pixel units 10, and an example in which one pixel unit 10 includes three sub-pixels is described, which is not limited in this embodiment. In addition, fig. 3 only illustrates that one side of the pixel units in the same row is flush with each other and the opening areas of all the sub-pixels belonging to one pixel unit 10 are equal, and the invention is not limited thereto.
Specifically, the aperture area of the pixel unit 10 is the sum of the aperture areas of all the sub-pixels belonging to the same pixel unit 10. In this embodiment, the opening area of at least one pixel unit 10 located in the main display area a0 is larger than the opening area of the pixel unit 10 of the first auxiliary display area FA1, that is, the opening area of the first auxiliary display area FA1 is reduced, so as to reduce the brightness of the first auxiliary display area, and achieve the purpose of reducing the external interference. The display panel provided by the invention can be suitable for a liquid crystal display panel or an organic light-emitting display panel.
In some alternative embodiments, as shown in fig. 4, fig. 4 is another partial structure diagram of the region Q1 in fig. 2. Referring to fig. 4, the geometric centers of the respective sub-pixels of the pixel units 10 located in the same row are located on the same straight line along the first direction X. Therefore, the light rays emitted from the opening areas of the sub-pixels can not be emitted from the opening areas of the adjacent sub-pixels, the first auxiliary display area FA1 can not generate the phenomena of light leakage or color cast when in display, and the user experience is improved.
In some alternative embodiments, with continued reference to fig. 4, the number of pixel cells 10 disposed within a unit area of the main display area a0 is equal to the number of pixel cells 10 disposed within a unit area of the first auxiliary display area FA 1. In the invention, the number of the pixel units 10 in the unit area of the main display area A0 is equal to the number of the pixel units 10 in the unit area of the first auxiliary display area FA1, and the opening area of the first auxiliary display area FA1 is reduced, so that the brightness of the first auxiliary display area is reduced, the aim of reducing external interference is fulfilled, the chromaticity and the resolution of the first auxiliary display area FA1 are not influenced, and the smoothness of the display picture of the first auxiliary display area FA1 is ensured.
In some alternative embodiments, with continued reference to fig. 4, the pixel unit 10 includes a plurality of sub-pixels 11, the sub-pixels 11 including a first sub-pixel 101, a second sub-pixel 102, and a third sub-pixel 103; in the main display area a0, the opening area of the first sub-pixel 101 is a1, the opening area of the second sub-pixel 102 is a2, and the opening area of the third sub-pixel 103 is a 3; in the first auxiliary display area FA1, the opening area of the first subpixel 101 is b1, the opening area of the second subpixel 102 is b2, and the opening area of the third subpixel 103 is b 3; wherein, a1+ a2+ a3 > b1+ b2+ b3, a 1: a 2: a3 ═ b 1: b 2: b3.
it should be noted that, in the embodiment of the present invention, it only needs to satisfy a1+ a2+ a3 > b1+ b2+ b3, where a 1: a 2: a3 ═ b 1: b 2: b3, the areas of the first sub-pixel 101, the second sub-pixel 102 and the third sub-pixel 103 are not specifically limited in the present invention, and may be equal or unequal. In fig. 4, only three sub-pixels 11 belonging to the same pixel unit 10 are described as having the same area.
Specifically, in the present invention, the sum of the areas of the three sub-pixels 11 in the same pixel unit 10 in the main display area a0 (i.e., a1+ a2+ a3) is made larger than the sum of the areas of the three sub-pixels 11 in the same pixel unit 10 in the first auxiliary display area FA1 (i.e., b1+ b2+ b3), and the ratios of the areas of the corresponding sub-pixels 11 are made equal (i.e., a 1: a 2: a 3: b 1: b 2: b 3). That is, while the opening area of the first auxiliary display area FA1 is reduced, the ratio of the areas of the different sub-pixels 11 in the same pixel unit 10 in the main display area a0 is ensured to be equal to the ratio of the areas of the different sub-pixels 11 in the same pixel unit 10 in the first auxiliary display area FA1, so that when the first auxiliary display area FA1 and the main display area a0 display the same picture, except for the brightness difference, no difference is provided, the display effect of the first auxiliary display area FA1 is ensured, and the user experience is improved.
In some alternative embodiments, referring to fig. 5 and 6, fig. 5 is a schematic view of a further partial structure of the region Q1 in fig. 2; fig. 6 is a schematic cross-sectional view along section C-C of fig. 5. The display panel further includes a thin film transistor array layer 40 on one side of the substrate base plate 30, an organic light emitting device layer 60 on one side of the thin film transistor array layer 40 away from the substrate base plate 30, a pixel definition layer PDL (pixel definition layer) on one side of the organic light emitting device layer 60 away from the substrate base plate 30, a black matrix layer 70 on one side of the pixel definition layer PDL away from the substrate base plate 30, and a color filter layer 80 on one side of the black matrix layer 70 away from the substrate base plate 30; the organic light emitting device layer 60 includes a plurality of organic light emitting elements, the pixel defining layer PDL includes a plurality of first open regions 31, the black matrix layer 70 includes a plurality of second open regions 32; the organic light emitting element at least partially overlaps the first open area 31, and the second open area 32 at least partially overlaps the first open area 31 in a direction perpendicular to the plane of the underlying substrate 30.
It should be noted that the thin film transistor array layer 40 generally further includes a polysilicon layer 41, a gate insulating layer 43, a first metal layer 43, an interlayer insulating layer 44, and a second metal layer 45; the gate insulating layer 43 includes an inorganic layer such as silicon oxide, silicon nitride, or a metal oxide, and may be a single layer or a multilayer. The thin film transistor array layer 40 further includes a plurality of thin film transistors T including an active layer Tp on the polysilicon layer 41, a gate electrode Tg on the first metal layer 43, and a source electrode Ts and a drain electrode Td on the second metal layer 45. A first insulating layer 51 is also typically disposed between the organic light emitting device layer 60 and the thin film transistor array layer 40.
The organic light emitting device layer 60 includes a first electrode 61 (e.g., an anode), a light emitting structure 60 (e.g., a light emitting material), and a second electrode 63 (e.g., a cathode) stacked, and the light emitting structure 62 emits light under a pressure difference between the first electrode 61 and the second electrode 63 when displaying. Illustratively, the light emitting structure 62 may include a first light emitting structure 621 emitting a first color light, a second light emitting structure 622 emitting a second color light, and a third light emitting structure 623 emitting a third color light. Alternatively, the light emitting structure 62 may further include a white light emitting structure emitting white light. In the embodiment of the present invention, only the light emitting structure 62 of the first sub-pixel 101 is taken as the first light emitting structure 621 emitting the first color light, the light emitting structure 62 of the second sub-pixel 102 is taken as the second light emitting structure 622 emitting the second color light, and the light emitting structure 62 of the third sub-pixel 103 is taken as the third light emitting structure 623 emitting the third color light.
It should be noted that the display panel may employ a thin Film encapsulation layer tfe (thin Film encapsulation). Because inorganic materials have strong blocking capability to water and oxygen, in order to realize effective encapsulation of the display panel, at least one inorganic encapsulation layer is usually included in the thin film encapsulation layer TFE, and when the thin film encapsulation layer TFE includes a plurality of stacked encapsulation layers, and the encapsulation layer closest to the display film layer is the inorganic encapsulation layer, the encapsulation effect is better.
In addition, in the present embodiment, only the OLED display panel with the top emission structure is taken as an example for description. The present embodiment will be described by taking an example in which the color filter layer 80 includes a first color resist 81 capable of emitting light of a first color, a second color resist 82 emitting light of a second color, and a third color resist 83 emitting light of a third color. Note that when the color filter layer 80 is provided on the light-emitting side of the organic light-emitting device, the light-emitting structures 62 of the organic light-emitting device layer 60 may all be light-emitting materials that emit white light; when the light emitting structure 62 of the organic light emitting device layer 60 includes light emitting materials capable of emitting a plurality of different colors, the color resistance belonging to one sub-pixel together with the light emitting structure 62 capable of emitting a certain color must also be capable of emitting the same color of light. For example, referring to fig. 5 and 6, if the sub-pixel 101 in the main display area a0 is a red sub-pixel, the light emitting structure 621 can emit red light, and the color resistor 81 is a red color resistor; the sub-pixel 102 is a green sub-pixel, the light emitting structure 622 can emit green light, and the color resistor 82 is a green color resistor; the sub-pixel 103 is a blue sub-pixel, the light emitting structure 623 can emit blue light, and the color resistor 83 is a blue color resistor. Similarly, the sub-pixel 101 in the first auxiliary display area FA1 is a red sub-pixel, the light emitting structure 621 can emit red light, and the color resistor 81 is a red color resistor; the sub-pixel 102 is a green sub-pixel, the light emitting structure 622 can emit green light, and the color resistor 82 is a green color resistor; the sub-pixel 103 is a blue sub-pixel, the light emitting structure 623 can emit blue light, and the color resistor 83 is a blue color resistor.
The color filter layer 80 and the black matrix layer 70 are formed on the packaged organic light-emitting element (namely, an OLED device) by utilizing photoetching, so that a circular polarizer of the existing OLED display panel is eliminated, the bending flexibility of the OLED display panel can be well realized, meanwhile, the circular polarizer for eliminating ambient light in the original OLED display panel can be eliminated due to the absorption effect of the black matrix layer 70 and the color filter layer 80 on the ambient light, the light-emitting utilization rate of the organic light-emitting element is improved under the condition of ensuring the consistency of the ambient light reflectivity level, and the picture contrast is improved.
In this embodiment, the positions of the display regions where the sub-pixels 11 are disposed are defined by disposing the pixel definition layer PDL, and the light emitted from the organic light emitting element corresponding to each sub-pixel 11 is emitted through the first opening region 31 on the pixel definition layer PDL, and then emitted through the second opening region 32 on the black matrix 70 corresponding to each sub-pixel 11 again, and finally reaches the human eyes. The organic light emitting element at least partially overlaps the first open area 31 and the second open area 32 at least partially overlaps the first open area 31 in a direction perpendicular to the plane of the base substrate 30, thereby ensuring that light emitted from the organic light emitting element can be incident on the human eye.
It should be noted that, in an actual manufacturing process, the first opening region 31 is usually formed in the PDL, and then the organic light emitting element is formed at the position of the first opening region 31, in a sense that the first opening region 31 of the pixel defining layer PDL defines an area where the organic light emitting element can emit light. The black matrix layer 70 is typically a black light-shielding material, and the second opening region 32 disposed thereon can also define light-exiting regions and non-light-exiting regions through the black matrix layer 70. In other words, in the direction perpendicular to the plane of the substrate base plate 30, the area of the overlapping portion of the first opening region 31 and the second opening region 32 corresponding to the same sub-pixel 11 is the opening area. Referring to fig. 5 and 6, for the sub-pixel 101 located at the first auxiliary display area FA1, the first opening area 331 and the second opening area 341 correspond to the same sub-pixel 101, and the first opening area 331 surrounds the second opening area 341 in the direction perpendicular to the plane of the substrate base plate 30, so that, for the sub-pixel 101 located at the first auxiliary display area FA1, the opening area thereof is finally equal to the projection area of the second opening area 341 in the direction perpendicular to the plane of the substrate base plate 30. For the sub-pixel 101 located in the main display area a0, the first opening area 311 and the second opening area 321 correspond to the same sub-pixel 101, and in the direction perpendicular to the plane of the substrate 30, the first opening area 311 and the second opening area 321 completely overlap, so that, for the sub-pixel 101 located in the main display area a0, the opening area is finally equal to the projection area of the first opening area 311 in the direction perpendicular to the plane of the substrate 30, and also equal to the projection area of the second opening area 321 in the direction perpendicular to the plane of the substrate 30.
In some alternative embodiments, with continued reference to fig. 5 and 6, the center of the first open area 31 overlaps the center of the second open area 32 in a direction perpendicular to the plane of the substrate base 30.
It is to be understood that the center in the present invention is a geometric center. By overlapping the center of the first opening area 31 and the center of the second opening area 32 corresponding to the same sub-pixel 11 in the direction perpendicular to the plane of the substrate 30, the light emitted from the organic light emitting device located in the first opening area 31 can be emitted from the second opening area 32 of the black matrix layer 70 well, thereby improving the utilization rate of the light, reducing the power consumption of the display panel, and prolonging the service life of the display panel.
In some alternative embodiments, with continuing reference to fig. 5, 6 and 7, fig. 7 is a partial structural schematic view of region Q2 of fig. 5. The area of the first opening area 311 corresponding to the first sub-pixel 1011 located at the main display area A0 is equal to the area of the first opening area 331 corresponding to the first sub-pixel 1012 located at the first auxiliary display area FA 1; the area of the first opening area 312 corresponding to the second sub-pixel 1021 in the main display area A0 is equal to the area of the first opening area 332 corresponding to the second sub-pixel 1022 in the first auxiliary display area FA 1; the area of the first open region 313 corresponding to the third sub-pixel 1031 located in the main display region a0 is equal to the area of the first open region 333 corresponding to the third sub-pixel 1032 located in the first auxiliary display region FA 1.
Specifically, in the embodiment of the present invention, the area of the first opening region 311 corresponding to the first subpixel 1011 and the first subpixel 1012 is equal to the area of the first opening region 331, the area of the first opening region 312 corresponding to the second subpixel 1021 and the second subpixel 1022 is equal to the area of the first opening region 332, and the area of the first opening region 313 corresponding to the third subpixel 1031 and the third subpixel 1032 is equal to the area of the first opening region 333. That is, on the pixel definition layer PDL, the areas of the first opening areas provided on the main display area a0 and the first auxiliary display FA1 are equal for the same color of the sub-pixels 11. Since the opening area of the pixel unit 10 located in the first auxiliary display area FA1 is smaller than the opening area of the pixel unit 10 located in the main display area a0, and the pixel unit 10 includes a plurality of sub-pixels 11, the opening area of the sub-pixels 11 depends on the areas of the first opening area 31 located in the pixel defining layer PDL and the second opening area 32 located in the black matrix layer 70 corresponding thereto, and the overlapping area of the projections of the two on the plane perpendicular to the substrate base plate 30. Therefore, the area of the second open area 321 corresponding to the first sub-pixel 1011 is larger than the area of the second open area 341 corresponding to the first sub-pixel 1012, the area of the second open area 322 corresponding to the second sub-pixel 1021 is larger than the area of the second open area 342 corresponding to the second sub-pixel 1022, and the area of the second open area 323 corresponding to the third sub-pixel 10311 is larger than the area of the second open area 343 corresponding to the third sub-pixel 1032.
In the present embodiment, the aperture area of the pixel unit 10 located in the first auxiliary display area FA1 is made smaller than the aperture area of the pixel unit 10 located in the main display area a0 by adjusting the area of the second opening area 32 located in the black matrix layer 70 by equalizing the areas of the first opening areas 31 provided in the main display area a0 and the first auxiliary display FA1 for the sub-pixels 11 of the same color on the pixel definition layer PDL. Compared with the scheme of adjusting the area of the first opening on the pixel definition layer PDL on the first auxiliary display FA1 to realize the area difference of the sub-pixels 11 of the same color in different areas (the main display area a0 and the first auxiliary display FA1), the embodiment of the present invention can reduce the deformation and the strength difference of the main display area a0 and the first auxiliary display FA1 caused by the tension force, thereby ensuring the process yield.
In some alternative embodiments, referring to fig. 8, fig. 8 is a schematic view of a further partial structure of the region Q1 in fig. 2. The pixel unit 10 includes a first pixel unit 12 and a second pixel unit 13, the first pixel unit 12 and the second pixel unit 13 each include a plurality of sub-pixels 11, and the sub-pixels 11 include a first sub-pixel 101, a second sub-pixel 102, and a third sub-pixel 103; the first pixel units 12 and the second pixel units 13 are alternately arranged in the second direction Y; the first pixel unit 12 includes a first sub-unit 121 and a second sub-unit 122 arranged along a first direction X, the first sub-unit 121 includes a first sub-pixel 101 and a second sub-pixel 102 arranged along a second direction Y, and the second sub-unit 122 includes a third sub-pixel 103; the second pixel unit 13 includes a second sub-unit 122 and a first sub-unit 121 arranged in the first direction X.
It should be noted that, since the first pixel unit 12 and the second pixel unit 13 are alternately arranged along the second direction Y, the first pixel unit 12 includes the first sub-unit 121 and the second sub-unit 122 arranged along the first direction X, and the second pixel unit 13 includes the second sub-unit 122 and the first sub-unit 121 arranged along the first direction X, the first sub-unit 121 and the second sub-unit 122 are alternately arranged along the second direction Y. The first sub-unit 121 includes a first sub-pixel 101 and a second sub-pixel 102 arranged along the second direction Y, and the second sub-unit 122 includes a third sub-pixel 103, so that a column of sub-pixels includes the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 along the second direction Y.
