Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
As shown in fig. 1, the present embodiment provides a display device 10. The display device 10 may include a display panel 100 and a driving controller 200, among others.
In detail, the driving controller 200 is electrically connected to the display panel 100, and is configured to send a control signal to the display panel 100 to control a display state of the display panel 100.
It is understood that the control process and principle of the display panel 100 by the driving controller 200 are not limited, and may be configured according to the actual application requirement, and therefore, the detailed description is omitted here.
With reference to fig. 2, an embodiment of the present application further provides a display panel 100, which can be applied to the display device 10. The display panel 100 includes a light emitting layer 110 and a touch layer 130.
In detail, the light emitting layer 110 includes a light emitting unit 111 and a pixel defining layer 113, the pixel defining layer 113 includes a pixel defining body 113a and a pixel opening 113b, and the light emitting unit 111 is located in the pixel opening 113 b. The touch layer 130 includes a first conductive structure 131 and an adjusting structure 137, the orthographic projection of the first conductive structure 131 on the light emitting layer 110 is located on the pixel defining body 113a, and the adjusting structure 137 is used for adjusting the brightness attenuation difference of the light emitting unit 111 in at least two directions.
Based on the above arrangement, since the light emitted from the light emitting layer 110 through the light emitting unit 111 passes through the touch layer 130, by adding the adjusting structure 137 in the touch layer 130, the light can be adjusted before being output to the outside of the display panel 100, so as to adjust the brightness attenuation difference of the light in at least two directions, reduce the brightness attenuation difference of the light in at least two directions, and further improve the problem that the existing display device 10 has a large brightness difference in different directions during the display process.
It is to be understood that, in the above example, the brightness attenuation difference is used to represent a difference of brightness attenuation values in the at least two directions, and the brightness attenuation values are used to represent the brightness attenuation of the light-emitting unit 111 in the corresponding directions.
As shown in connection with fig. 3, the at least two directions include a first direction (F1 shown in fig. 3), a second direction (F2 shown in fig. 3), a third direction (F3 shown in fig. 3), and a fourth direction (F4 shown in fig. 3). The luminance attenuation value is used to represent the difference between the luminance value corresponding to an angle in one direction (direction F1 shown in fig. 3) and the luminance value corresponding to zero degrees.
For example, a luminance difference value between 45 degrees and 0 degrees in the first direction may be used as a luminance attenuation value of 45 degrees in the first direction. A luminance difference value between 45 degrees and 0 degrees in the second direction may be used as a luminance attenuation value of 45 degrees in the second direction. A difference in luminance between 45 degrees and 0 degrees in the third direction may be used as a luminance attenuation value of 45 degrees in the third direction. A luminance difference value between 45 degrees and 0 degrees in the fourth direction may be used as a luminance attenuation value of 45 degrees in the fourth direction. Wherein the 0 degrees in the four directions coincide with each other.
Based on this, the brightness attenuation difference may be a difference between 4 brightness attenuation values of the brightness attenuation value of 45 degrees in the first direction, the brightness attenuation value of 45 degrees in the second direction, the brightness attenuation value of 45 degrees in the third direction, and the brightness attenuation value of 45 degrees in the fourth direction.
In the first aspect, it should be noted that, in an alternative example, the light emitting layer 110 may include light emitting units 111 of three different colors, such as a red light emitting unit (R), a green light emitting unit (G), and a blue light emitting unit (B). It is understood that one of the light emitting units 111 may refer to one sub-pixel.
Wherein the relative positional relationship between the light emitting cells 111 of different colors is not limited.
For example, in an alternative example, a red light emitting unit, a green light emitting unit, a blue light emitting unit, a.
For another example, in another alternative example, a red light emitting unit, a green light emitting unit, a blue light emitting unit, a green light emitting unit, a red light emitting unit, a green light emitting unit, a blue light emitting unit, and a green light emitting unit may be sequentially included in one direction.
It is understood that in an alternative example, in conjunction with fig. 4, the display panel 100 further includes an encapsulation layer 120. The encapsulation layer 120 may be located between the light emitting layer 110 and the touch layer 130.
It is understood that, in an alternative example, the light emitting layer 110 may be located on one side of the array substrate, for example, the array substrate may be located on one side of the light emitting unit 111 and the pixel defining body 113a away from the touch layer 130. A transistor array may be integrated on the array substrate, and the transistor array may be used to drive the light emitting unit 111.
In the second aspect, it is noted that, for the touch layer 130, in an alternative example, the first conductive structure 131 may include a plurality of conductive portions 132, and an orthogonal projection of each conductive portion 132 on the light emitting layer 110 is located on the pixel defining body 113 a.
Alternatively, in an alternative example, in order to avoid a large difference in attenuation of light in different directions of the light emitting layer 110 by the first conductive structure 131, the first conductive structure 131 and the pixel opening 113b in the light emitting layer 110 have the following positional relationship:
each side of the pixel opening 113b has the same distance as the orthogonal projection of the adjacent conductive portion 132 on the light emitting layer 110.
Wherein, the side of the pixel opening 113b adjacent to the conductive portion 132 may refer to: the conductive portion 132 is adjacent to the side of the pixel opening 113b in an orthogonal projection of the light emitting layer 110. Based on this, the conductive portion 132 adjacent to each side of the pixel opening 113b can be made to have a high uniformity of the influence of each side on the light output from the light emitting unit 111 in the direction in which each side is located, so that the difference in luminance in different directions is small.
In the present embodiment, considering that there is a pixel opening 113b in the pixel defining layer 113, which may be non-square (e.g. rectangular) in shape, the conductive portion 132 corresponding to the pixel opening 113b may be correspondingly disposed, so that the distance between each side of the non-square pixel opening 113b and the orthographic projection of the adjacent conductive portion 132 on the light emitting layer 110 is the same.
In detail, the pixel opening 113b may be a plurality of openings, and at least one of the pixel openings 113b has a non-square shape. For example, the light emitting unit 111 may include a first color light emitting unit, a second color light emitting unit, and a third color light emitting unit, and correspondingly, the pixel opening 113b may include a first pixel opening, a second pixel opening, and a third pixel opening corresponding to the first color light emitting unit, the second color light emitting unit, and the third color light emitting unit, respectively, and at least one of the first pixel opening, the second pixel opening, and the third pixel opening may have a non-square shape. The output light of the first color light emitting unit is transmitted to the touch layer 130 after passing through the first pixel opening. The output light of the second color light emitting unit passes through the second pixel opening and then is transmitted to the touch layer 130. The output light of the third color light emitting unit passes through the third pixel opening and then is transmitted to the touch layer 130. Based on this, the present embodiment provides the following two examples, respectively.
For example, in an alternative example, the first conductive structure 131 and the pixel opening 113b have the following positional relationship:
each non-square pixel opening 113b corresponds to a ring-shaped structure formed by a plurality of conductive portions 132, each conductive portion 132 included in the ring-shaped structure corresponds to one side of the non-square pixel opening 113b, the distances between the orthographic projection of each conductive portion 132 on the light-emitting layer 110 and the corresponding side of the pixel opening 113b are the same, and the widths of the plurality of conductive portions 132 included in the ring-shaped structure are the same.
Based on this, the inner contour of the ring-shaped structure can be made to be the same as the shape of the outer contour.
In order to explain the above example, a specific application example is provided in conjunction with fig. 5, and in this application example, the light emitting unit 111 may include a red light emitting unit, a green light emitting unit, and a blue light emitting unit, which are sequentially arranged. Based on the requirement of white light modulation, the pixel openings 113b corresponding to the red light emitting unit and the blue light emitting unit, such as the first pixel opening and the third pixel opening, may be square, and the pixel opening 113b corresponding to the green light emitting unit, such as the second pixel opening, may be rectangular.
The orthographic projection of the annular structure formed by the plurality of conductive portions 132 corresponding to the first pixel opening on the light-emitting layer 110 is annular a, the orthographic projection of the annular structure formed by the plurality of conductive portions 132 corresponding to the second pixel opening on the light-emitting layer 110 is annular B, and the orthographic projection of the annular structure formed by the plurality of conductive portions 132 corresponding to the third pixel opening on the light-emitting layer 110 is annular C.
In this way, on the basis that the widths of the plurality of conductive portions 132 included in the ring-shaped structure are the same, in order to make the distance between each side of the pixel opening 113B and the orthographic projection of the adjacent conductive portion 132 on the light emitting layer 110 the same, the inner contour and the outer contour of the ring-shaped a and the ring-shaped C are square, and the inner contour and the outer contour of the ring-shaped B are rectangular.
For another example, in another alternative example, the first conductive structure 131 and the pixel opening 113b have the following positional relationship:
each non-square pixel opening 113b corresponds to a ring-shaped structure formed by a plurality of conductive portions 132, each conductive portion 132 included in the ring-shaped structure corresponds to one side of the non-square pixel opening 113b, the distances between the orthographic projection of each conductive portion 132 on the light-emitting layer 110 and the corresponding side of the pixel opening 113b are the same, and the widths of at least two conductive portions 132 in the plurality of conductive portions 132 included in the ring-shaped structure are different;
based on this, the inner contour and the outer contour of the ring-shaped structure can be made different in shape.
To explain the above example, a specific application example is provided in conjunction with fig. 6, and in this application example, the light emitting unit 111 may include a red light emitting unit, a green light emitting unit, and a blue light emitting unit, which are sequentially arranged. Based on the requirement of white light modulation, the pixel openings 113b of the red light emitting unit and the blue light emitting unit, such as the first pixel opening and the third pixel opening, may be square, and the pixel opening 113b of the green light emitting unit, such as the second pixel opening, may be rectangular.
The orthographic projection of the annular structure formed by the plurality of conductive portions 132 corresponding to the first pixel opening on the light emitting layer 110 is annular D, the orthographic projection of the annular structure formed by the plurality of conductive portions 132 corresponding to the second pixel opening on the light emitting layer 110 is annular E, and the orthographic projection of the annular structure formed by the plurality of conductive portions 132 corresponding to the third pixel opening on the light emitting layer 110 is annular F.
Based on this, for the ring-shaped structure corresponding to the first pixel opening and the third pixel opening, the width of the plurality of conductive portions 132 included in the ring-shaped structure is the same. In order to make the distance between each side of the first pixel opening and the orthographic projection of the adjacent conductive part 132 on the light emitting layer 110 the same, and the distance between each side of the third pixel opening and the orthographic projection of the adjacent conductive part 132 on the light emitting layer 110 the same, the inner contour and the outer contour of the ring shape D and the ring shape E are square.
For the ring-shaped structure corresponding to the second pixel opening, in order to make the distance between each side of the second pixel opening and the orthographic projection of the adjacent conductive part 132 on the light emitting layer 110 the same, the ring-shaped structure includes four conductive parts 132, two opposite conductive parts 132 have the same width, and two adjacent conductive parts 132 have different widths. Thus, the inner contour of the ring B is different from the outer contour in shape, for example, the inner contour of the ring B is rectangular, and the outer contour of the ring B is square.
It should be further noted that the number of the adjusting structures 137 may be multiple for the touch layer 130. In a plurality of the adjustment structures 137, there is a space between at least two adjustment structures 137. Based on different uses of the adjustment structures 137, positions of the adjustment structures 137 in the touch layer 130 may also be different. In the present embodiment, the following three different examples are provided based on different requirements, respectively.
In a first alternative example, referring to fig. 7, the first conductive structure 131 and the adjusting structure 137 are located in the same structural layer in the touch layer 130, and an orthogonal projection of each adjusting structure 137 on the light emitting layer 110 is at least partially located in the pixel opening 113 b. For example, the orthographic projection of the adjusting structure 137 on the light emitting layer 110 may be entirely located in the pixel opening 113b, or may be partially located in the pixel opening 113 b.
The adjusting structure 137 is configured to increase the light emitting brightness of the output light of the light emitting unit 111 after passing through the touch layer 130. Based on this, since the attenuation values of the output light of the light emitting unit 111 are different in different directions, and the adjusting structure 137 has different increasing actions on the brightness of the output light in different directions, the brightness difference of the output light of the light emitting unit 111 in different directions can be reduced after providing a large brightness increasing action on the output light with a large attenuation value and providing a small brightness increasing action on the output light with a small attenuation value.
Optionally, a specific manner of increasing the brightness of the output light of the light emitting unit 111 by the adjusting structure 137 is not limited, and may be selected according to actual application requirements.
For example, in an alternative example, in conjunction with fig. 8, the touch layer 130 further includes a first transparent material layer 133 and a second transparent material layer 134. The first transparent material layer 133 is located on a side of the adjusting structure 137 and the first conductive structure 131 close to the light emitting layer 110, the second transparent material layer 134 is located on a side of the adjusting structure 137 and the first conductive structure 131 far away from the light emitting layer 110, and a refractive index of the first transparent material layer 133 is different from a refractive index of the second transparent material. Based on this, the refractive index of the adjusting structure 137 is between the refractive index of the first transparent material layer 133 and the refractive index of the second transparent material layer, so that an anti-reflection film layer is formed by the first transparent material layer 133, the adjusting structure 137 and the second transparent material layer 134, thereby increasing the light-emitting brightness of the output light of the light-emitting unit 111.
It is understood that, on the basis of the above example, in conjunction with fig. 9, it is considered that the touch layer 130 may further include a third transparent material layer 135 and a second conductive structure 136. Based on this, in order to make the adjusting structure 137 have a better adjusting effect on the brightness of the output light of the light emitting unit 111, the third transparent material layer 135 is located on the side of the first transparent material layer 133 close to the light emitting layer 110, and the second conductive structure 136 is located between the first transparent material layer 133 and the third transparent material layer 135.
It is understood that, in order to avoid the second conductive structure blocking the transmission of the output light of the light emitting unit 111, the orthographic projection of the second conductive structure on the light emitting layer 110 may be located on the pixel defining body 113 a. For example, the second conductive structure may also include a plurality of portions, and an orthographic projection of each portion on the light emitting layer 110 may be located on the pixel defining body 113a, as may be correspondingly arranged with reference to the positions of the plurality of conductive portions 132 in the above example.
In a second alternative example, referring to fig. 10, the adjusting structures 137 are located on a side of the first conductive structure 131 close to the light emitting layer 110, and an orthogonal projection of each of the adjusting structures 137 on the light emitting layer 110 is at least partially located on the pixel defining body 113a, for example, the orthogonal projection of the adjusting structure 137 on the light emitting layer 110 may be located on the pixel defining body 113a entirely or partially located on the pixel defining body 113 a.
The adjusting structure 137 is configured to adjust a light-shielding angle of the first conductive structure 131 to output light of the light-emitting unit 111.
It is to be understood that, when the first conductive structure 131 includes a plurality of conductive portions 132, the adjusting structure 137 may be in a corresponding plurality, such that each conductive portion 132 may be located at a side of the corresponding adjusting structure 137 away from the light emitting layer 110. In this way, since the plurality of adjusting structures 137 are added, the distance between each conductive portion 132 and the light emitting unit 111 can be changed, and thus, the light-shielding angle of each conductive portion 132 to the output light of the light emitting unit 111 can be adjusted.
For example, in an alternative example, before the adjusting structure 137 is not added, the distance between the conductive part 132 and the light emitting unit 111 is L1, there is a block to the output light of 45 degrees in a part direction, and there is no block to the output light of 45 degrees in a part direction, so that the brightness difference between the output lights of 45 degrees in different directions is large. After the adjustment structure 137 is added, the distance between the conductive part 132 and the light emitting unit 111 is L1+ L2, which has a block to the output light of 30 degrees in a part direction and has no block to the output light of 30 degrees in a part direction, and thus has no block to the output light of 45 degrees in different directions, so that the brightness difference of the output light of 45 degrees in different directions is small.
That is, in the above example, if the brightness difference at a specific angle needs to be reduced, the adjustment structure 137 may be added to adjust the shading angle of the output light.
It is understood that, on the basis of the above example, in conjunction with fig. 11, the touch layer 130 may further include a first transparent material layer 133, a second transparent material layer 134, a third transparent material layer 135, and a second conductive structure 136.
