Detailed Description
The embodiment of the invention provides a display device, aiming at the problems that in the prior art, due to the fact that the pixel density of a functional region is low, the functional region has strong granular sensation in display and the boundary line of the functional region is quite obvious.
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of a display device according to an embodiment of the present invention are described in detail below with reference to the accompanying drawings. 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.
Certain features of the drawings are shown exaggerated in drawing form in order to facilitate understanding, and the shapes and sizes of the components in the drawings are not true to scale and are merely intended to illustrate the present disclosure.
It should be noted that, in the description of the embodiments of the present invention, the terms "first", "second", and the like are used for distinguishing between the description and the drawings, and are not to be construed as indicating or implying any relative importance or order. "plurality" in the description of the embodiments of the present invention means two or more.
The term "and/or" in the embodiment of the present invention is only one kind of association relationship describing an associated object, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
Specifically, fig. 1 is a schematic structural view of a display device according to an embodiment of the present invention, and fig. 2 is a cross-sectional view of the display device cut along the direction AA' shown in fig. 1.
As shown in fig. 1 and 2, the display device includes a display panel 01 and a camera module 02 disposed below the display panel. The display panel 01 includes a first display region a1 and a second display region a2 surrounding the first display region a 1. The projection of the camera module 02 on the display panel 01 is located in the first display area a1, and the area within the circular dotted line shown in fig. 1 is the projection area of the camera module 02.
The first display region a1 includes a plurality of sub-pixel regions and a plurality of light transmission regions, the second display region a2 includes a plurality of sub-pixel regions, and the distribution density of the sub-pixel regions in the first display region a1 is less than the distribution density of the sub-pixel regions in the second display region a 2.
It should be understood that, in the embodiment of the present invention, the distribution density of the sub-pixel regions of a certain region refers to a ratio of a total area of all sub-pixel regions in the region to a total area of the region, for example: the distribution density of the sub-pixel regions in the first display region a1 is equal to the ratio of the total area of all the sub-pixel regions in the first display region a1 to the total area of the first display region a1, and the distribution density of the sub-pixel regions in the second display region a2 is equal to the ratio of the total area of all the sub-pixel regions in the second display region a2 to the total area of the second display region a 2.
In fig. 1, the magnitude of the distribution density of the sub-pixel region is illustrated by the lightness of the filling color, wherein the deeper the filling color, the greater the distribution density of the sub-pixel region. As can be seen from fig. 1, within the first display region a1, the distribution density of the sub-pixel regions gradually increases from the central region of the first display region a1 toward a direction away from the central region of the first display region a 1.
Fig. 3 shows a schematic diagram of pixel distribution of five local positions, i.e., S1, S2, S3, S4, and S5, on a display area, where S1, S2, S3, and S4 are in the first display area a1, and the distance from the center is in a size relationship: s1< S2< S3< S4. The distribution densities of the sub-pixel regions on S1, S2, S3, S4 and S5 are respectively: 50%, 60%, 70%, 80%, 100%. It can be seen that the distribution density of the sub-pixel regions is greater at positions farther from the central region of the first display region a1 within the first display region a 1.
Of course, the arrangement of 5 sub-pixel regions and light-transmitting regions shown in fig. 3 is only an example, and other arrangements may be used in the specific implementation, as long as the rule that the farther the position in the first display region a1 from the central region of the first display region a1, the greater the distribution density of the sub-pixel regions is satisfied, and the arrangement of the sub-pixel regions and the light-transmitting regions in the embodiment of the present invention is not limited.
Further, in the embodiment of the present invention, the display panel may include sub-pixel regions of multiple colors, such as a red sub-pixel (R), a green sub-pixel (G), a blue sub-pixel (B), and the like, which is not limited in this embodiment of the present invention. The pixel opening area of the same-color sub-pixel region in the first display region a1 is smaller than the pixel opening area in the second display region a 2.
Still taking the above five local positions as examples, please refer to fig. 4, where S1, S2, S3, S4, S5 all include R, G, B three-color sub-pixel regions, where the R, G, B three-color sub-pixel region on S1 is respectively represented by R1, G1, B1, the R, G, B three-color sub-pixel region on S2 is respectively represented by R2, G2, B2, the R, G, B three-color sub-pixel region on S3 is respectively represented by R3, G3, B3, the R, G, B three-color sub-pixel region on S4 is respectively represented by R4, G4, B4, and the R, G, B three-color sub-pixel region on S5 is respectively represented by R5, G5, B5. The pixel opening area size relationship of the sub-pixel regions at each position satisfies: r1< R5, R2< R5, R3< R5, R4< R5, G1< G5, G2< G5, G3< G5, G4< G5, B1< B5, B2< B5, B3< B5, B4< B5.
In the display device provided by the embodiment of the invention, when the display panel 01 of the display device includes the first display region a1 and the second display region a2, and the camera module 02 is disposed below the first display region a1, the distribution density of the sub-pixel regions in the first display region a1 is set to be smaller than the distribution density of the sub-pixel regions in the second display region a2, the pixel opening area of the sub-pixel regions in the first display region a1 is set to be smaller than the pixel opening area of the sub-pixel regions in the second display region a2, the distribution density of the sub-pixel regions in the first display region a1 is set to gradually increase from the central region of the first display region a1 to a direction away from the central region of the first display region a1, so that the distribution density of the sub-pixel regions can be uniformly transited from the first display region a1 to the second display region a2 while ensuring sufficient transmittance in the first display region a1, therefore, the problems that the first display area A1 has stronger graininess and the boundary line between the first display area A1 and the second display area A2 is obvious due to lower pixel density of the first display area A1 are solved, and the display effect of the display device is improved.
Optionally, in the display device provided in the embodiment of the present invention, the distribution density of the sub-pixel regions located at any position in the first display region a1 is in a direct function relationship with the distance from the any position to the central region of the first display region a 1. In this way, the sense of boundary of the first display area a1 can be weakened to the utmost extent, so that the pixel densities of the first display area a1 and the second display area a2 are more uniformly transited, and the display effect of the display device is further improved.
Optionally, in the display device provided in the embodiment of the present invention, the center of the first display area a1 is on the center area of the first display area a 1. The first display region a1 further includes an edge region, and the edge region of the first display region a1 is located outside the central region of the first display region a1 and is distributed in a ring shape. For example, as shown in fig. 5, where O1 is a central region of the first display region a1, and E1 is an edge region of the first display region a 1.
Optionally, in the display device provided in the embodiment of the present invention, the sub-pixel region and the light-transmitting region in the first display region a1 have the same shape and size, and the sub-pixel region and the light-transmitting region are distributed in an array.
For example, as shown in fig. 3 and 4, the sub-pixel region and the light-transmitting region are rectangles having the same shape and size. Of course, in a specific implementation process, the shapes of the sub-pixel region and the light-transmitting region may also be other shapes, such as a circle, an ellipse, a triangle, and other polygons, and this is not limited in the embodiment of the present invention.
This embodiment sets the sub-pixel region and the light transmission region in the first display region a1 to have the same shape and size, and is array distribution, can make display panel's pixel arrange more neatly for display device display effect is more even.
Optionally, in the display device provided in the embodiment of the present invention, as shown in fig. 6, an area of a projection of the camera module 02 on the display panel 01 is smaller than a preset first area threshold, and the projection of the camera module 02 on the display panel 01 is located in a central area O1 of the first display area a 1.
This embodiment, when camera module 02 is less, set up camera module 02 in first display area A1 the minimum also the regional below that the luminousness is the highest of subpixel distribution density, can make camera module 02 can the sensitization better, improve the image quality of shooing.
Optionally, in the display device provided in the embodiment of the present invention, as shown in fig. 7, an area of a projection of the camera module 02 on the display panel 01 is greater than a preset second area threshold, the projection of the camera module 02 on the display panel 01 covers a central area O1 of the first display area a1, and a projection of the minimum aperture 201 of the camera module 02 on the display panel 01 is located in a central area O1 of the first display area a 1.
In this embodiment, when the camera module 02 is large, the minimum aperture of the camera module 02 is located below the region where the distribution density of the sub-pixels is minimum, that is, the light transmittance is highest, in the first display region a1, so that the area of the first display region a1 (that is, the low pixel density region) can be reduced as much as possible while the camera module 02 can be well sensitive to light, and the overall display effect of the display device is improved.
Optionally, in view of the problem that the photosensitive effect of the camera module 02 is poor due to the excessively high pixel density, in the display device provided in the embodiment of the present invention, the distribution density of the sub-pixel regions in the central region of the first display region a1 is less than or equal to 50%, for example, the distribution density of the sub-pixel regions is 50% in S4 (located on the central region O1) shown in fig. 3. In this way, it is possible to ensure that the display device has a good image capturing effect while improving the display effect of the first display area a 1.
Alternatively, the distribution density of the edge area of the first display area a1 and the sub-pixel area of the second display area a2 is 100%.
For an example, referring to fig. 8, the edge area may specifically be composed of sub-pixel areas that are crossed by an edge line of a circle with a preset length as a radius and a center of the first display area a1, that is, all of the edge areas are sub-pixel areas, that is, the distribution density of the sub-pixel areas of the edge area is 100%. It should be noted that, in order to clearly show the positions of the edge regions in fig. 8, fig. 8 does not show the distribution of the sub-pixel regions in the other regions except the edge region on the first display region a1 and the distribution of the sub-pixel regions on the second display region a 2.
In this embodiment, the distribution density of the sub-pixel region in the edge region of the first display region a1 is set to be consistent with the distribution density of the sub-pixel region of the second display region a2, that is, both are 100%, so that the abrupt change of the pixel density at the junction between the first display region a1 and the second display region a2 can be better avoided, the boundary feeling of the first display region a1 is further weakened, the pixel density of the first display region a1 and the pixel density of the second display region a2 are more uniformly transited, and the display effect of the display device is further better improved.
Alternatively, in the display device provided in the embodiment of the present invention, in the first display region a1, the pixel opening area of the sub-pixel region of the same color gradually increases from the central region of the first display region a1 to a direction away from the central region of the first display region a 1.
Taking five local positions of S1, S2, S3, S4, and S5 shown in fig. 4 as an example, the pixel aperture area of the R color sub-pixel region satisfies: r1< R2< R3< R4< R5.
In the present embodiment, in the first display region a1, the pixel opening area of the sub-pixel region of the same color is set to gradually increase from the central region of the first display region a1 to a direction away from the central region of the first display region a1, so that the pixel opening area of the sub-pixel region of the same color uniformly transitions from the central region of the first display region a1 to the second display region a1, which can further improve the problem that the boundary line between the first display region a1 and the second display region a2 is obvious, and improve the light transmittance of the first display region a1, so that the camera module 02 can better sense light, and improve the image capturing quality of the display device.
Optionally, in the display device provided in the embodiment of the present invention, the opening area of the sub-pixel region of the same color located in the edge region of the first display region a1 is positively correlated with the distance from the sub-pixel region to the central region of the first display region a1, for example, may be in a proportional function relationship.
For example, referring to fig. 9, the sub-pixel regions a, b, and c on the edge region are all located at the edge region of the first display region a1, and the sub-pixels on the sub-pixel regions a, b, and c have the same color (for example, all are red), and the distance relationship between the sub-pixel regions a, b, and c and the center of the first display region a1 is: a < b < c, the pixel aperture area of the sub-pixel regions a, b, c has the following relationship: a < b < c.
In this embodiment, the transition of the pixel opening area of the same color sub-pixel region from the edge region of the first display region a1 to the second display region a1 can be made more uniform, and the problem of the conspicuous boundary line between the first display region a1 and the second display region a2 can be further improved.
Optionally, in the display device according to the embodiment of the present invention, in the second display region a2, the pixel aperture areas of the sub-pixel regions of the same color are the same. Thus, the uniformity of the display effect of the first display area can be further ensured.
Optionally, the first display area a1 in the display device provided in the embodiment of the present invention may be in other positions besides the central position at the top of the display panel shown in fig. 1 to fig. 7, for example, in an upper left corner position of the display panel, as shown in fig. 10, or in an upper right corner position of the display panel, as shown in fig. 11, which is not limited in this respect.
Alternatively, the first display area a1 in the display device provided in the embodiment of the present invention may be in a shape other than the circle shown in fig. 1 to 7, such as a rounded rectangle shown in fig. 12, a triangle shown in fig. 13, or another polygon, and the embodiment of the present invention is not limited in particular.
Optionally, in the display device provided in the embodiment of the present invention, a projection shape of the camera module on the display panel 01 may be a circle as shown in fig. 1 to 8, or may be another shape, such as a rectangle, a triangle, or another polygon, and the embodiment of the present invention is not limited specifically.
Optionally, in the display device provided in the embodiment of the present invention, please refer to fig. 14 and 15, the display device further includes a fingerprint identification module 03 disposed below the display panel 01. Fig. 15 is a cross-sectional view of the display device cut along the direction BB' shown in fig. 14.
As shown in fig. 14 and 15, the display panel 01 further includes a third display area A3, the second display area a2 surrounds the third display area A3, and the projection of the fingerprint identification module 03 on the display panel 01 is located in the third display area A3. As shown in fig. 14, the circular dotted area on the third display area a3 is the projection area of the fingerprint identification module 03.
Similar to the first display region a1, the third display region A3 includes a plurality of sub-pixel regions and a plurality of light-transmitting regions, and the distribution density of the sub-pixel regions in the third display region A3 is less than the distribution density of the sub-pixel regions in the second display region a 2. Further, since the requirement of the fingerprint recognition module 03 for light transmittance is lower than the requirement of the camera module 02 for light transmittance, the distribution density of the entire sub-pixel region in the third display region A3 is higher than the distribution density of the entire sub-pixel region in the first display region a 1.
In fig. 14, the magnitude of the distribution density of the sub-pixel regions is characterized by the lightness of the fill color, wherein the deeper the fill color, the greater the distribution density of the sub-pixel regions, and as can be seen from fig. 14, in the third display region A3, the distribution density of the sub-pixel regions gradually increases in a direction from the central region of the third display region A3 to a direction away from the central region of the third display region A3.
Further, since the requirement of the fingerprint recognition module 03 on the light transmittance is lower than that of the camera module 02, the pixel aperture area of the sub-pixel region of the same color in the third display region A3 is smaller than that in the second display region a 2.
For example, fig. 16 shows a schematic diagram of pixel distribution of seven local positions, i.e., S1, S2, S3, S4, S5, S6, and S7 on the display region, where S1, S2, S3, and S4 are in the first display region a1, and the distance from the center of the first display region a1 satisfies S1< S2< S3< S4, and the distribution densities of the sub-pixel regions on S1, S2, S3, and S4 are: 50%, 60%, 70% and 80%. S5 the distribution density of the sub-pixel regions on S5 is 100% on the second display region. S6 and S7 are in the third display area A3, and the distance from the center of the third display area A3 satisfies S6< S7, and the distribution densities of the sub-pixel areas on S6 and S7 are respectively: 70 percent and 90 percent. Where S6 is at the center position of the third display region A3 and S1 is at the center position of the first display region a1, it is apparent that the distribution density of the sub-pixel region at S6 > the distribution density of the sub-pixel region at S1.
It should be noted that the arrangement of the sub-pixel regions and the light-transmitting regions in the third display region shown in fig. 16 is only an example, and other arrangements may be used in the specific implementation, as long as the rule that the farther the position from the central region of the third display region A3 in the third display region A3, the greater the distribution density of the sub-pixel regions is satisfied, and the arrangement of the sub-pixel regions and the light-transmitting regions in the embodiment of the present invention is not limited.
In the embodiment of the present invention, when the display device further includes the third display region A3 and the fingerprint recognition module 03 is disposed under the third display region A3, the distribution density of the sub-pixel regions in the third display region A3 is set to be smaller than the distribution density of the sub-pixel regions in the second display region a2 and larger than the distribution density of the sub-pixel regions in the first display region a1, and the distribution density of the sub-pixel regions is gradually increased from the central region of the third display region A3 to a direction away from the central region of the third display region A3, and the pixel aperture area of the sub-pixel regions of the same color in the third display region A3 is smaller than the pixel aperture area in the second display region a2, so that the distribution density of the sub-pixel regions can be uniformly transited from the third display region A3 to the second display region a2 while ensuring sufficient transmittance of the third display region A3, therefore, the problems that the third display area A3 has stronger graininess and the boundary line between the third display area A3 and the second display area A2 is obvious due to lower pixel density of the third display area A3 are solved, and the display effect of the display device is further improved.
Optionally, in the display device provided in the embodiment of the present invention, the center of the third display area A3 is on the center area of the third display area A3, the third display area A3 further includes an edge area, and the edge area of the third display area A3 is located outside the center area of the third display area A3 and is distributed in a ring shape.
Optionally, in the display device provided in the embodiment of the present invention, the sub-pixel regions and the light-transmitting regions in the third display region a3 have the same shape and size, and the sub-pixel regions and the light-transmitting regions are distributed in an array.

Optionally, in the display device provided in the embodiment of the present invention, a distribution density of the sub-pixel regions in the edge region of the third display region a3 is 100%. Specific implementation of the edge region of the third display region A3 can refer to the specific implementation of the edge region of the first display region a1 shown in fig. 8, and details thereof are not repeated here.
In the embodiment, the distribution density of the sub-pixel region in the edge region of the third display region A3 is set to be consistent with the distribution density of the sub-pixel region of the second display region a2, namely, both are 100%, so that the sudden change of the pixel density at the junction of the third display region A3 and the second display region a2 can be better avoided, the boundary feeling of the third display region A3 is further weakened, the pixel density of the third display region A3 and the pixel density of the second display region a2 are more uniformly transited, and the display effect of the display device is further better improved.
Alternatively, in the display device provided in the embodiment of the present invention, in the third display region A3, the pixel opening area of the sub-pixel region of the same color gradually increases from the central region of the third display region A3 to a direction away from the central region of the third display region A3. In this way, the pixel opening areas of the sub-pixel regions of the same color can be made to uniformly transition from the central region of the third display region A3 to the second display region a1, and the problem of the boundary line between the third display region A3 and the second display region a2 being conspicuous can be further improved.
Optionally, in the display device according to the embodiment of the present invention, an opening area of a sub-pixel region of the same color located in an edge region of the third display region A3 is positively correlated with a distance from the sub-pixel region to a central region of the third display region A3. In this way, the transition of the pixel opening area of the sub-pixel region of the same color from the edge region of the third display region A3 to the second display region a1 can be made more uniform, and the problem of the conspicuous boundary line between the third display region A3 and the second display region a2 can be further improved.
