[ detailed description ] embodiments
For better understanding of the technical solutions of the present invention, the following detailed descriptions of the embodiments of the present invention are provided with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be understood that the term "and/or" as used herein is merely one type of association that describes an associated object, meaning that three relationships may exist, e.g., a and/or B may mean: 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.
It should be understood that although the terms first, second, etc. may be used herein to describe devices in accordance with embodiments of the present invention, these devices should not be limited by these terms. These terms are only used to distinguish one device from another. For example, the first light-transmitting region may also be referred to as a second light-transmitting region, and similarly, the second light-transmitting region may also be referred to as a first light-transmitting region without departing from the scope of embodiments of the present invention.
As shown in fig. 1, fig. 1 is a schematic structural diagram of a display panel in the prior art, the display panel includes a display area 1', and the display area 1' includes a fingerprint identification area 2 '. The display region 1' is provided with a pixel defining layer 3', the pixel defining layer 3 includes openings 4', and a light transmitting region 5' is provided between two adjacent openings 5 '. When the display panel displays images, light emitted by the light-emitting element is emitted out through the opening 4'; when carrying out fingerprint identification, light after the reflection of touch subject (like the finger) jets into the fingerprint identification module through the printing opacity district 5 'of fingerprint identification district 2', and then discerns the fingerprint. However, under current mode of setting, the area of printing opacity district 5' is less in fingerprint identification district 2', when carrying out fingerprint identification, just also less to the light quantity of fingerprint identification module via touch subject reflection, leads to fingerprint identification's detection precision not high.
Based on this, an embodiment of the present invention provides a display panel, as shown in fig. 2 and fig. 3, fig. 2 is a top view of the display panel provided in the embodiment of the present invention, fig. 3 is a schematic cross-sectional view of the display panel provided in the embodiment of the present invention, and the display panel includes a pixel definition layer 1 and a plurality of fingerprint identification modules 2; the pixel definition layer 1 defines a plurality of first light-emitting areas 3 arranged in a matrix, the pixel definition layer 1 comprises a plurality of first light-transmitting areas 4, the first light-transmitting areas 4 are located between two adjacent first light-emitting areas 3 in the first direction, and the fingerprint identification module 2 is overlapped with the first light-transmitting areas 4.
In addition, the display panel further comprises a first fingerprint identification area 5; in the first fingerprint identification section 5, a dimension K1 of the first light emitting area 3 in a first direction is smaller than a dimension K2 of the first light emitting area 3 in a second direction, the first direction being perpendicular to the second direction.
First, it can be understood that, in order to drive the display panel to normally emit light, referring to fig. 3 again, the display panel further includes a pixel driving circuit 6 and a light emitting element 7, wherein the light emitting element 7 is located on a side of the pixel driving circuit 6 facing the light emitting surface, the light emitting element 7 includes an anode layer 8, a light emitting layer 9 and a cathode layer 10 which are stacked, the pixel defining layer 1 is located between the anode layer 8 and the cathode layer 10, and the first light emitting region 3 of the pixel defining layer 1 is used for defining the light emitting layer 9.
Compared with the prior art, in the display panel provided in the embodiment of the present invention, by adjusting the arrangement manner of the first light-emitting areas 3 in the first fingerprint identification area 5, the longer edges of the first light-emitting areas 3 extend along the second direction, and the shorter edges extend along the first direction, so that the space occupied by the first light-emitting areas 3 in the first direction can be reduced, and the distance between two adjacent first light-emitting areas 3 in the first direction can be increased. Since the first light-transmitting region 4 is located between two first light-emitting regions 3 adjacent to each other in the first direction, the area of the first light-transmitting region 4 in the first fingerprint identification region 5 is correspondingly increased. The inventor researches and discovers that for first light emitting areas 3 with the same shape and the same area, the distance between two adjacent first light emitting areas 3 in the first direction is about 70 μm by adopting the arrangement mode in the prior art, and the distance between two adjacent first light emitting areas 3 in the first direction can be increased to 84 μm by adopting the arrangement mode of the embodiment of the invention, so that the area of a first light transmission area 4 is increased by 36 percent, and the area of the first light transmission area 4 is remarkably increased.
Therefore, by adopting the display panel provided by the embodiment of the invention, the area of the first light-transmitting area 4 in the first fingerprint identification area 5 can be effectively increased by adjusting the setting mode of the first light-emitting area 3 in the first fingerprint identification area 5, so that when a touch main body (such as a finger) touches the display panel, light reflected by the touch main body can be emitted into the fingerprint identification module 2 through the first light-transmitting area 4 of the first fingerprint identification area 5 to a greater extent, the amount of reflected light received by the fingerprint identification module 2 is increased, and the fingerprint identification precision is further improved.
It should be noted that only a partial area of the display panel shown in fig. 1 is multiplexed as the first fingerprint identification area 5, which is only a schematic illustration, and in other alternative embodiments of the present invention, the entire area of the display area may also be multiplexed as the first fingerprint identification area 5. When only a partial area of the display area is multiplexed as the first fingerprint identification area 5, the arrangement of the first light-emitting areas 3 in the area of the display area other than the first fingerprint identification area 5 may be the same as or different from the arrangement of the first light-emitting areas 3 in the first fingerprint identification area 5.
Optionally, referring to fig. 2 again, the pixel defining layer 1 further defines a plurality of second light emitting areas 11 arranged in a matrix, an area of the second light emitting areas 11 is larger than an area of the first light emitting area 3, and the first light emitting area 3 and the second light emitting area 11 are spaced from each other in the second direction; the first light-transmitting region 4 is located between two second light-emitting regions 11 adjacent in the second direction. In the first fingerprint identification area 5, the distance L1 between two adjacent second light emitting areas 11 in the second direction is greater than the distance L2 between the first light emitting area 3 and the second light emitting area 11 adjacent in the second direction.
In the embodiment of the present invention, the first light-emitting areas 3 and the second light-emitting areas 11 are spaced from each other in the second direction, which means that the second light-emitting areas 11, the second light-emitting areas 11 and the first light-emitting areas 3 are sequentially and cyclically arranged in the second direction.
Note that the first light-emitting region 3 and the second light-emitting region 11 are used to define the light-emitting layers 9 of the different color sub-pixels. For example, taking the display panel including the red sub-pixel, the green sub-pixel and the blue sub-pixel as an example, since the lifetimes of the blue sub-pixel and the green sub-pixel are shorter than that of the red sub-pixel, in order to reduce the current densities of the blue sub-pixel and the green sub-pixel, the lifetimes of the blue sub-pixel and the green sub-pixel are attenuated more slowly, and the lifetimes of the three color sub-pixels are ensured to be similar, the second light emitting region 11 with a larger area may be used to define the light emitting layer 9 of the blue sub-pixel and the green sub-pixel, and the first light emitting layer 9 with a smaller area may be used to define the light emitting layer 9 of the red sub-pixel.
Based on the arrangement of the first light emitting areas 3 and the second light emitting areas 11, when the first light transmitting area 4 is located between two adjacent second light emitting areas 11 in the second direction, the length of the first light transmitting area 4 in the second direction is defined by the distance between the two adjacent second light emitting areas 11. In the first light-transmitting region 4, by making L1 larger than L2, on the one hand, the distance between two adjacent second light-emitting regions 11 in the second direction can be increased, thereby increasing the length of the first light-transmitting region 4 in the second direction and further increasing the area of the first light-transmitting region 4; on the other hand, by reducing the distance between two adjacent first light-emitting regions 3 and second light-emitting regions 11 in the second direction, it can also be ensured that the sum of the distances between two adjacent second light-emitting regions 11 and between two adjacent first light-emitting regions 3 and second light-emitting regions 11 in the second direction is not changed, so that the sub-pixel distribution density in the second direction is not changed, that is, the resolution is not changed.
Optionally, as shown in fig. 4, fig. 4 is another top view of the display panel provided in the embodiment of the present invention, and the display panel may further include a second fingerprint identification area 12. In the second fingerprint identification area 12, a dimension K3 of the first light emitting area 3 in the first direction is larger than a dimension K4 of the first light emitting area 3 in the second direction.
In the second fingerprint identification region 12, the longer edge of the first light-emitting region 3 extends in the first direction and the shorter edge extends in the second direction, that is, the area of the first light-transmitting region 4 in the second fingerprint identification region 12 is smaller than that of the first fingerprint identification region 5. Therefore, when the display panel includes both the first fingerprint identification area 5 and the second fingerprint identification area 12, the first fingerprint identification area 5 having a higher light transmittance may be disposed in an area where a user touches at a high frequency, so as to achieve more accurate identification of the user's fingerprint.
For example, as shown in fig. 5, fig. 5 is a schematic layout view of a first fingerprint identification area and a second fingerprint identification area provided in an embodiment of the present invention, where the first fingerprint identification area 5 is located at a side close to a lower border of a display panel; alternatively, as shown in fig. 6, fig. 6 is another schematic layout diagram of the first fingerprint identification area and the second fingerprint identification area according to the embodiment of the present invention, and in the first direction, one second fingerprint identification area 12, the first fingerprint identification area 5, and another second fingerprint identification area 12 are sequentially arranged.
And, through further set up second fingerprint identification district 12 in display panel, increased the total area of fingerprint identification district in the display panel to increased the total reflection light ray volume that fingerprint identification module 2 received, also can improve fingerprint identification precision to a certain extent.
Optionally, referring to fig. 4 again, in the first fingerprint identification area 5, the distance between two adjacent first light-emitting areas 3 in the first direction is a first distance H1, and in the second fingerprint identification area 12, the distance between two adjacent first light-emitting areas 3 in the first direction is a second distance H2; to ensure that the first light-transmitting area 4 in the first fingerprint identification area 5 touched by the user at a high frequency has a larger area, the first distance H1 may be larger than the second distance H2.
In addition, in order to further ensure that the area of the first light-transmitting area 4 in the first fingerprint identification area 5 is effectively increased, so that the first fingerprint identification area 5 has higher light transmittance, the ratio of the first spacing H1 to the second spacing H2 can be larger than 1.2.
Alternatively, referring to fig. 4 again, in the second fingerprint identification area 12, a distance L3 between two adjacent second light emitting areas 11 in the second direction is equal to a distance L4 between the first light emitting area 3 and the second light emitting area 11 adjacent in the second direction. With the arrangement, the first light-emitting area 3 and the second light-emitting area 11 in the second fingerprint identification area 12 can be uniformly distributed, and when the display panel emits light, the light emitted by the light-emitting element 7 in the second fingerprint identification area 12 is uniformly emitted through the first light-emitting area 3 and the second light-emitting area 11, so that the display performance of the second fingerprint identification area 12 is improved.
Optionally, referring to fig. 4 again, in the first fingerprint identification area 5, the distance between two adjacent second light emitting areas 11 in the second direction is a third distance L1; a distance between two second light emitting areas 11 adjacent in the second direction within the second fingerprint identification area 12 is a fourth pitch L3; the third spacing L1 is greater than the fourth spacing L3.
Compared with the second fingerprint identification area 12, the distance between two adjacent second light emitting areas 11 in the first fingerprint identification area 5 is larger, so that the area of the first light transmission area 4 in the first fingerprint identification area 5 is larger, and the identification precision of the area touched by a user at a high frequency is higher. On this premise, the distance between two adjacent second light emitting areas 11 in the second fingerprint identification area 12 is smaller, so that the second light emitting areas 11 in the second fingerprint identification area 12 are arranged more closely, that is, the distribution density of sub-pixels in the second fingerprint identification area 12 is improved, thereby ensuring that the second fingerprint identification area 12 has higher resolution.
In addition, in order to further ensure that the first fingerprint identification area 5 has a higher light transmittance and the second fingerprint identification area 12 has a higher sub-pixel distribution density, the ratio of the third distance L1 to the fourth distance L3 may be greater than 1.1.
Alternatively, as shown in fig. 7 and 8, fig. 7 is a schematic diagram of a layout structure of a storage capacitor provided in an embodiment of the present invention, and fig. 8 is another schematic cross-sectional diagram of a display panel provided in an embodiment of the present invention, where the display panel includes a plurality of pixel driving circuits 6, the pixel driving circuits 6 are located between the pixel defining layer 1 and the fingerprint identification module 2, and the pixel driving circuits 6 include storage capacitors 13. In the first fingerprint identification area 5 the electrode plates of the storage capacitor 13 have a first area and in the second fingerprint identification area 12 the electrode plates of the storage capacitor 13 have a second area, the first area being smaller than the second area.
Usually, the electrode plate of the storage capacitor 13 is made of a metal material, and based on the opaque property of the metal material, when a touch subject (such as a finger) touches the display panel, part of the reflected light is blocked by the electrode plate and cannot be further transmitted to the fingerprint identification module 2. In the embodiment of the invention, the shielding degree of the electrode plate to the reflected light can be effectively reduced by reducing the area of the electrode plate in the first fingerprint identification area 5, so that the reflected light is shot into the fingerprint identification module 2 to a greater extent, the amount of the reflected light received by the fingerprint identification module 2 in the first fingerprint identification area 5 is further increased, and the fingerprint identification precision is improved.
Alternatively, the distribution density of the first light-emitting areas 3 in the first fingerprint identification area 5 is equal to the distribution density of the first light-emitting areas 3 in the second fingerprint identification area 12; and the distribution density of the second light emitting areas 11 in the first fingerprint identification area 5 is equal to the distribution density of the second light emitting areas 11 in the second fingerprint identification area 12. So set up, can guarantee that the distribution density of sub pixel is the same in first fingerprint identification district 5 and second fingerprint identification district 12, resolution ratio is the same promptly, like this, when display panel shows the picture, the difference of two regional display pictures is less, has improved user's sight shadow experience.
Alternatively, when the first light emitting region 3 and the second light emitting region 11 are formed, the first light emitting region 3 may be made to assume an irregular shape, and the second light emitting region 11 may be made to assume a regular shape.
As shown in fig. 9, fig. 9 is a schematic structural diagram of a display device according to an embodiment of the present invention, and the display device includes the display panel 100. The specific structure of the display panel 100 has been described in detail in the above embodiments, and is not described herein again. Of course, the display device shown in fig. 9 is only a schematic illustration, and the display device may be any electronic device with a display function, such as a mobile phone, a tablet computer, a notebook computer, an electronic book, or a television.
Since the display device provided by the embodiment of the invention includes the display panel 100, by adjusting the setting manner of the first light-emitting region 3 of the first fingerprint identification region 5 in the display panel, the area of the first light-transmitting region 4 in the first fingerprint identification region 5 can be effectively increased, so that when a touch subject (such as a finger) touches the display device, light reflected by the touch subject can be emitted into the fingerprint identification module 2 via the first light-transmitting region 4 of the first fingerprint identification region 5 to a greater extent, the amount of reflected light received by the fingerprint identification module 2 is increased, and further the fingerprint identification accuracy of the display device is increased.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
