The interconnection area BC is an area of the non-display area BB other than the high-transmission area BD, and specifically includes an area where the signal trace 20 is provided, an area between the area where the signal trace 20 is provided and the display area AA, the width H1 of the area may be 40 μm, for example, an area BF between two adjacent high-transmission areas BD, and an area BH between the area where the signal trace 20 is provided and the high-transmission areas BD. In order to facilitate the design of the sub-pixels in the display panel 10, the sub-pixels are also disposed in the area BF between two adjacent high-transmittance areas BD, but the sub-pixels in this area are not displayed.
The wiring region BC is disposed around the high-transmittance region BD, that is, the wiring region BC is located at the periphery of the high-transmittance region BD and forms a closed shape at the periphery of the high-transmittance region BD. The vertical projection of the light shielding layer 50 on the plane of the cover plate 30 is located in a surrounding area of the vertical projection of the first part 21 on the plane of the cover plate 30 and the vertical projection of the second part 61 on the plane of the cover plate 30, that is, the shape formed by the vertical projection of the first part 21 on the plane of the cover plate 30 and the vertical projection of the second part 61 on the plane of the cover plate 30 is located outside the vertical projection of the light shielding layer 50 on the plane of the cover plate 30, and a continuous and closed shape is formed at the periphery of the vertical projection of the light shielding layer 50 on the plane of the cover plate 30.
The signal traces 20 in this embodiment are traces that provide corresponding signals for the internal structure of the display panel 10 to enable the display panel to work normally, and the signal traces 20 may include, for example, touch traces, data lines, scan lines, and the like, and the embodiment does not specifically limit the types of the signal traces 20.
Specifically, the cover plate 30 is provided to protect the display panel 10, thereby preventing water and oxygen from corroding the internal structure of the display panel 10. Set up light shield layer 50 in the one side that apron 30 is close to display panel 10, and the high light transmission district BD is located the first fretwork portion BE of light shield layer 50 in the planar vertical projection of apron 30 place at the planar vertical projection of apron 30 place, can shelter from the peripheral light of high light transmission district BD through light shield layer 50 promptly, prevent that unnecessary light leak from having an influence to the performance of the light sense device that high light transmission district BD set up, and avoided process error to lead to that light shield layer 50 can not cover the region that wiring district BC is close to high light transmission district BD completely, make the unnecessary light leak have an influence through the performance of this region to the camera that high light transmission district BD set up.
Specifically, since the first part 21 of the signal trace 20 is exposed, and thus, the reflection and/or absorption of the light at the position where the first part 21 is exposed and the reflection and/or absorption of the area where the signal trace is not exposed to the external light are different, which results in a visual difference, the embodiment makes the reflection and/or absorption of the light around the light shielding layer 50 to the external light tend to be consistent by providing the visual compensation layer 60, and thus, the problem of the display uniformity affected by the visual difference between the area where the first part 21 is exposed and the area where the signal trace is not provided, which are caused by only exposing the first part 21 in the prior art, is avoided.
Optionally, the reflectivity of the visual compensation layer 60 is a, the reflectivity of the signal trace 20 is B, and | a-B |/B is greater than 0 and less than or equal to 50%. For example, 12%, 25%, 50%, etc., by setting the relationship between the reflectivity of the vision compensation layer 60 and the reflectivity of the signal trace 20 to 0 < | a-B |/B ≦ 50%, it is ensured that the reflection and/or absorption of the external light around the light shielding layer 50 tend to be uniform.
Alternatively, the material of the vision compensation layer 60 may be the same as the material of the signal trace 20, for example; alternatively, the material of the visual compensation layer 60 may further include, for example, a mixture of carbon black powder and an antistatic liquid or a metal ink material, wherein the metal ink material may be, for example, a combination of silver, copper, and an oxide, and particularly, the ratio of silver, copper, and an oxide may be adjusted to achieve a uniform effect. It should be noted that the material of the vision compensation layer 60 includes, but is not limited to, the above examples, and those skilled in the art can select the material of the vision compensation layer 60 according to the actual situation.
In the actual setting, the specific position of the visual compensation layer and the shape of the visual compensation layer can be set in various ways. The following is a detailed description of exemplary embodiments and is not intended to limit the invention.
Optionally, the display module further includes a polarizer, and the polarizer is disposed between the cover plate and the display panel; the visual compensation layer is arranged on the polaroid.
The polaroid can prevent the external environment light from being reflected out after being incident to the metal layer in the display panel, and further the display problem is influenced. The embodiment arranges the visual compensation layer on the polarizer, and avoids the problem that the metal layer inside the display panel is corroded when the visual compensation layer is prepared.
When the vision compensation layer is disposed on the polarizer, there are also various ways in which the shape and position of the vision compensation layer on the polarizer may be disposed.
For example, fig. 8 is a schematic top view structure diagram of a polarizer according to an embodiment of the present invention, and with continued reference to fig. 5, 6, 7, and 8, the shape of the visual compensation layer 60 is a gourd shape, in which only a portion of the visual compensation layer 60 is exposed, and the exposed portion is the second sub-portion 61. In addition, since the perpendicular projection of the first part 21 on the plane of the cover 30 does not overlap with the perpendicular projection of the second part 61 on the plane of the cover 30, the second part 61 of the visual compensation layer 60 and the first part of the signal trace 20 are not covered by the light shielding layer 50, that is, the exposed portions of the non-display area BB of the display module 100 that can reflect and/or absorb the ambient light are the first part 21 and the second part 61. Meanwhile, the vertical projection of the light shielding layer 50 on the plane of the cover plate 30 is located in the surrounding area of the vertical projection of the first part 21 on the plane of the cover plate 30 and the vertical projection of the second part 61 on the plane of the cover plate 30, namely, the exposed pattern surrounded by the first part 21 and the second part 61 surrounds the light shielding layer 50, so that the reflection and/or absorption of the light around the light shielding layer 50 to the outside tend to be consistent, and the problem that in the prior art, the display uniformity is affected due to the fact that the area where the first part 21 is exposed and the area where no signal routing is arranged are different in vision due to the fact that only the first part 21 is exposed is solved.
Fig. 9 is a schematic top view of another polarizer according to an embodiment of the present invention, and as shown in fig. 9, unlike fig. 8, the vision compensation layer 60 in fig. 9 is only partially disposed. When the visual compensation layer 60 shown in fig. 8 is used, only the exposed second sub-portion 61 reflects and/or absorbs external light, and most of the exposed second sub-portion is covered by the light shielding layer 50, so the visual compensation layer 60 provided in this embodiment is the exposed second sub-portion 61. Meanwhile, since the vertical projection of the first sub-portion 21 on the plane of the cover plate 30 does not overlap with the vertical projection of the second sub-portion 61 on the plane of the cover plate 30, the exposed portions of the non-display area BB of the display module 100 that can reflect and absorb ambient light are the first sub-portion 21 and the second sub-portion 61, and the vertical projection of the light shielding layer 50 on the plane of the cover plate 30 is located in the surrounding area of the vertical projection of the first sub-portion 21 on the plane of the cover plate 30 and the vertical projection of the second sub-portion 61 on the plane of the cover plate 30, that is, the exposed pattern surrounded by the first sub-portion 21 and the second sub-portion 61 surrounds the light shielding layer 50, so that the reflection and/or absorption of the ambient light around the light shielding layer 50 tend to be consistent, and thus, the visual difference between the area where the first sub-portion 21 is exposed and the area where no signal trace is disposed due to the fact that only the first sub-portion 21 is exposed in the prior art is avoided, the problem of display uniformity is affected.
For example, fig. 10 is a schematic top view structure diagram of another display module according to an embodiment of the present invention, and fig. 11 is a schematic top view structure diagram of another polarizer according to an embodiment of the present invention, as shown in fig. 10 and fig. 11, the visual compensation layer 60 is located on the polarizer 40 and located in the step line region BC, and a shape profile of the visual compensation layer 60 is the same as a shape profile of the light shielding layer 50. The visual compensation layer 60 comprises a second hollowed-out part BI, the second hollowed-out part BI corresponds to the high light-transmitting area BD one by one, the aperture of the second hollowed-out part BI is larger than that of the first hollowed-out part BE, the arrangement of the second hollowed-out part BI ensures that a camera module arranged in the high light-transmitting area BD works normally, and meanwhile, the shape profile of the visual compensation layer 60 is the same as that of the light shielding layer 50, so that the process difficulty is reduced when the visual compensation layer is prepared, and the preparation efficiency of the display module 100 is improved. Since the perpendicular projection of the first subsection 21 on the plane of the cover 30 lies within the perpendicular projection of the second subsection 61 on the plane of the cover 30; the vertical projection of the light shielding layer 50 on the plane of the cover plate 30 is located in the surrounding area of the vertical projection of the second section 61 on the plane of the cover plate 30. That is, the exposed first part 21 of the signal trace 20 is shielded by the second part 61 of the visual compensation layer 60, only the second part 61 of the visual compensation layer 60 is exposed, and the light shielding layer 50 is located in the surrounding area of the second part 61. Because the periphery of the light-shielding layer 50 is only the second portion 61, the reflection and absorption of the second portion 61 to the external light are the same, so that the reflection and/or absorption of the periphery of the light-shielding layer 50 to the external light tend to be consistent, and thus, the problem that in the prior art, the display uniformity is influenced due to the fact that the area exposing the first subsection 21 is different from the area without the signal routing, which is caused by the fact that the first subsection 21 is only exposed, is solved.
Fig. 12 is a schematic top view of another polarizer according to an embodiment of the present invention, and as shown in fig. 12, unlike fig. 11, the vision compensation layer 60 in fig. 12 is only partially disposed. When the visual compensation layer 60 shown in fig. 11 is used, only the exposed second sub-portion 61 is activated, and most of the visual compensation layer 60 is covered by the light shielding layer 50 and is not activated, so the visual compensation layer 60 provided in this embodiment is the exposed second sub-portion 61, and at this time, the exposed portion of the non-display area BB of the display module 100 that can reflect and absorb the ambient light is the second portion 61, and the vertical projection of the light shielding layer 50 on the plane of the cover plate 30 is located in the surrounding area of the vertical projection of the second sub-portion 61 on the plane of the cover plate 30, that is, the pattern surrounded by the exposed second portion 61 surrounds the light shielding layer 50, so that the reflection and/or absorption of the external light around the light shielding layer 50 tend to be uniform.
It should be noted that the shape of the visual compensation layer 60 includes, but is not limited to, the above examples, and those skilled in the art can set the visual compensation layer 60 according to the actual situation of the product, as long as the reflection and/or absorption of the external light around the light shielding layer 50 tend to be uniform by setting the visual compensation layer.
Optionally, when the vision compensation layer is located the polaroid, set up the vision compensation layer in the one side that the polaroid deviates from display panel, then set up the bond line in one side that the polaroid set up the vision compensation layer, laminate apron and polaroid through the bond line, can also carry out the planarization to the vision compensation layer that sets up on the polaroid simultaneously, avoided when the vision compensation level is close to display panel one side in the polaroid, lead to the polaroid unevenness, influence display module's display effect and display module stability's problem.
The above examples take the case where the vision compensation layer is disposed on the polarizer as an example, and specific film layers and specific shapes of the vision compensation layer on the display panel when the vision compensation layer is disposed in the display panel will be specifically described below. The display panel may be a liquid crystal display panel or an organic light emitting diode display panel, and for more conveniently and clearly describing the subsequent schemes, the display panel is taken as an organic light emitting diode display panel as an example. None of the following is a limitation of the present application.
Optionally, the display panel includes at least one metal layer; the signal routing and the visual compensation layer are located on the same metal layer.
For example, fig. 13 is a schematic top view structure diagram of another display module provided in an embodiment of the present invention, fig. 14 is a schematic top view structure diagram of another display panel provided in an embodiment of the present invention, fig. 15 is a schematic partial film structure diagram of a display module provided in an embodiment of the present invention, as shown in fig. 13, fig. 14 and fig. 15, the display panel 10 provided in an embodiment of the present invention may include a first metal layer M1, a second metal layer M2, a third metal layer M3 and an insulating layer disposed between the metal layers, the display panel 10 further includes a substrate 11, a driving circuit 12 and an organic light emitting unit 13 stacked in sequence, and further includes a touch electrode 14 located on a side of the organic light emitting unit 13 away from the driving circuit 12. The signal trace 20 of the present embodiment is a touch trace. The first metal layer M1 includes the gate electrode 121 of the driving circuit 12, a scanning line, and the like (not shown in the figure); the second metal layer M2 includes a first electrode 122, a second electrode 123, a data line (not shown), and the like of the driving circuit 12, wherein the first electrode 122 is a source and the second electrode 123 is a drain, or, the first electrode 122 is a drain and the second electrode 123 is a source; the third metal layer M3 includes the touch electrode 14, the touch trace, and the vision compensation layer 60. When the vision compensation layer 60 and the touch trace are disposed on the same layer, the shape of the vision compensation layer 60 may be, for example, a gourd shape (as shown in fig. 14), and at this time, only a portion of the vision compensation layer 60 is exposed, and the exposed portion is the second partition 61. In addition, since the perpendicular projection of the first sub-portion 21 on the plane of the cover 30 does not overlap with the perpendicular projection of the second sub-portion 61 on the plane of the cover 30, the exposed portions of the non-display area BB of the display module 100 that can reflect and/or absorb the ambient light are the first sub-portion 21 and the second sub-portion 61. Since the material of the visual compensation layer 60 and the touch trace are formed by the same material through the same step, the reflection and absorption of the exposed second part 61 of the visual compensation layer 60 and the exposed first part 21 of the touch trace to the external environment light are the same, so that the reflection and/or absorption of the periphery of the light shielding layer 50 to the external light tend to be the same, and thus, the problem that the display uniformity is affected due to the fact that the area where the first part 21 is exposed and the area where the signal trace is not arranged are visually different due to the fact that only the first part 21 is exposed in the prior art is solved, and meanwhile, the visual compensation layer 60 can be simultaneously prepared when the touch trace is prepared without independently arranging the visual compensation layer 60, so that the process steps are simplified, and the preparation efficiency of the display module 100 is improved.
For example, fig. 16 is a schematic top view structure diagram of another display panel provided in an embodiment of the present invention, and as shown in fig. 16, unlike fig. 14, the visual compensation layer 60 in fig. 16 is only partially disposed. That is, the visual compensation layer 60 provided in this embodiment is the exposed second part 61, and also since the perpendicular projection of the first part 21 on the plane of the cover 30 does not overlap with the perpendicular projection of the second part 61 on the plane of the cover 30, the exposed portions of the non-display area BB of the display module 100 that can reflect and/or absorb the ambient light are the first part 21 and the second part 61. Since the material of the visual compensation layer 60 and the touch trace are prepared and formed by the same material and the same step, the reflection and absorption of the exposed second part 61 of the visual compensation layer 60 and the exposed first part 21 of the touch trace to the external environment light are the same, so that the reflection and/or absorption of the light shielding layer 50 to the external light tend to be the same.
It should be noted that fig. 13, 14, 15 and 16 only use the signal trace 20 as a touch trace, and the visual compensation layer 60 and the touch trace are disposed on the same layer as an example, but the present application is not limited thereto. In other alternative embodiments, the signal trace 20 may also be a scan line, and the first metal layer M1 includes the scan line and the vision compensation layer 60; alternatively, the signal trace 20 is a data line, and the second metal layer M2 includes the data line and the vision compensation layer 60.
Note that fig. 15 illustrates an example in which the touch electrode is provided separately, but the present application is not limited thereto. In other alternative embodiments, the touch electrode may also be disposed in the same layer as the cathode in the organic light emitting unit 13, that is, the cathode is reused as the touch electrode.
It will be understood by those skilled in the art that fig. 14 and 16 only show the visual compensation layer 60 and the signal traces 20 for clarity, but in practice, the organic light emitting diode display panel further includes other signal lines and devices, etc., which are not shown here.
Optionally, the display panel includes at least two metal layers; the signal routing and the visual compensation layer are respectively positioned on different metal layers.
For example, fig. 17 is a schematic top view structure diagram of another display module provided in an embodiment of the present invention, fig. 18 is a schematic top view structure diagram of another display panel provided in an embodiment of the present invention, fig. 19 is a schematic partial film structure diagram of a display module provided in an embodiment of the present invention, as shown in fig. 17, fig. 18 and fig. 19, a display panel 10 provided in an embodiment of the present invention may include a first metal layer M1, a second metal layer M2, a third metal layer M3, and an insulating layer disposed between the metal layers, the display panel 10 further includes a substrate 11, a driving circuit 12, and an organic light emitting unit 13 stacked in sequence, and further includes a touch electrode 14 located on a side of the organic light emitting unit 13 away from the driving circuit 12. The signal trace 20 of the present embodiment is a data line. The first metal layer M1 includes the gate electrode 121 of the driving circuit 12, a scanning line, and the like (not shown in the figure); the second metal layer M2 includes a first electrode 122, a second electrode 123, a data line, etc. of the driving circuit 12, wherein the first electrode 122 is a source and the second electrode 123 is a drain, or, namely, the first electrode 122 is a drain and the second electrode 123 is a source; the third metal layer M3 includes the touch electrode 14 and the vision compensation layer 60. When the visual compensation layer 60 and the touch electrode 14 are disposed on the same layer, the visual compensation layer 60 may be, for example, gourd-shaped (as shown in fig. 18), and since the vertical projection of the first sub-portion 21 on the plane of the cover 30 does not overlap with the vertical projection of the second sub-portion 61 on the plane of the cover 30, the exposed portions of the non-display area BB of the display module 100 that can reflect and/or absorb the ambient light are the first sub-portion 21 and the second sub-portion 61. Because the vertical projection of the light shielding layer 50 on the plane of the cover plate 30 is located in the surrounding area of the vertical projection of the first subsection 21 on the plane of the cover plate 30 and the vertical projection of the second subsection 61 on the plane of the cover plate 30, that is, the exposed figure surrounded by the first subsection 21 and the second subsection 61 surrounds the light shielding layer 50, the reflection and/or absorption of the external light around the light shielding layer 50 tend to be consistent; meanwhile, when the touch wiring is manufactured, the visual compensation layer 60 is manufactured at the same time, the visual compensation layer 60 does not need to be arranged independently, the process steps are simplified, and the manufacturing efficiency of the display module 100 is improved.
For example, fig. 20 is a schematic top view structure diagram of another display panel provided in an embodiment of the present invention, and as shown in fig. 20, unlike fig. 18, the visual compensation layer 60 in fig. 20 is only partially disposed. That is, the visual compensation layer 60 provided in this embodiment is the exposed second part 61, and similarly, since the vertical projection of the first part 21 on the plane of the cover 30 does not overlap with the vertical projection of the second part 61 on the plane of the cover 30, the exposed portions of the non-display area BB of the display module 100 that can reflect and/or absorb the ambient light are the first part 21 and the second part 61. And because the vertical projection of the light shielding layer 50 on the plane of the cover plate 30 is located in the surrounding area of the vertical projection of the first part 21 on the plane of the cover plate 30 and the vertical projection of the second part 61 on the plane of the cover plate 30, that is, the exposed figure surrounded by the first part 21 and the second part 61 surrounds the light shielding layer 50, the reflection and/or absorption of the light shielding layer 50 to the outside tend to be consistent.
For example, fig. 21 is a schematic diagram of a partial film structure of another display module according to an embodiment of the present invention, and fig. 22 is a schematic diagram of a top view structure of another display panel according to an embodiment of the present invention, as shown in fig. 21 and fig. 22, a shape profile of the vision compensation layer 60 is the same as a shape profile of the light shielding layer 50. Wherein, the visual compensation layer 60 includes second fretwork portion BI, second fretwork portion BI and high light-transmitting zone BD one-to-one, and the aperture of second fretwork portion BI is greater than the aperture of first fretwork portion BE, the setting up of second fretwork portion BI has guaranteed that the camera module that sets up in the high light-transmitting zone BD normally works, simultaneously because the shape profile of visual compensation layer 60 is the same with the shape profile of light shield layer 50, so when preparing the visual compensation layer, reduce the technology degree of difficulty, improve display module 100's preparation efficiency. And the perpendicular projection of the first part 21 on the plane of the cover 30 is located in the perpendicular projection of the second part 61 on the plane of the cover 30; the vertical projection of the light shielding layer 50 on the plane of the cover plate 30 is located in the surrounding area of the vertical projection of the second section 61 on the plane of the cover plate 30. That is, the exposed first part 21 of the signal trace 20 is shielded by the second part 61 of the visual compensation layer 60, only the second part 61 of the visual compensation layer 60 is exposed, and the light shielding layer 50 is located in the surrounding area of the second part 61. Because the periphery of the light shielding layer 50 is only the second portion 61, the reflection and absorption of the second portion 61 to the external light are the same, so that the reflection and/or absorption of the periphery of the light shielding layer 50 to the external light tend to be consistent, and thus, the problem that the display uniformity is influenced due to the fact that the area exposing the first part 21 is different from the area without the signal routing in the prior art because the first part 21 is only exposed is solved.
Fig. 23 is a schematic top view of another polarizer according to an embodiment of the present invention, and as shown in fig. 23, unlike fig. 22, the vision compensation layer 60 in fig. 23 is only partially disposed. That is, the vision compensation layer 60 provided in this embodiment is the exposed second sub-portion 61, and at this time, the portion exposed in the non-display area BB of the display module 100 and capable of reflecting and absorbing the ambient light is also the second portion 61, and the vertical projection of the light shielding layer 50 on the plane of the cover plate 30 is located in the surrounding area of the vertical projection of the second sub-portion 61 on the plane of the cover plate 30, that is, the pattern surrounded by the exposed second portion 61 surrounds the light shielding layer 50, so that the reflection and/or absorption of the light shielding layer 50 to the outside tends to be uniform.
It should be noted that fig. 17-23 only use the signal trace 20 as a data line, and the visual compensation layer 60 and the touch electrode 14 are disposed in the same layer, but this does not limit the present application, and those skilled in the art can set the position and shape of the visual compensation layer 60 according to the needs of the product.
Note that, although fig. 19 and 21 illustrate the touch electrode as being provided separately, the present invention is not limited thereto. In other alternative embodiments, the touch electrode may also be disposed in the same layer as the cathode in the organic light emitting unit 13, that is, the cathode is reused as the touch electrode.
It will be understood by those skilled in the art that fig. 18 and 20 simply show the vision compensation layer 60 and the signal traces 20 and fig. 22 and 23 simply show the vision compensation layer 60 for the sake of clarity in describing the shape of the vision compensation layer 60. In practice, however, the organic light emitting diode display panel further includes other signal lines, devices, and the like, which are not shown here.
On the basis of the above solution, when the perpendicular projection of the first section on the plane of the cover does not overlap with the perpendicular projection of the second section on the plane of the cover, optionally, with continued reference to fig. 5, 13 and 17, the width H3 of the first section 21 is the same as the width H2 of the second section 61 in the first direction; the first direction is perpendicular to a connecting line between centers of two adjacent high-transmittance areas BD. When the width H3 of the first section 21 is the same as the width H2 of the second section 61, the absorption and reflection of the external ambient light by the first section 21 and the second section 61 are the same, thus further reducing the problem of visual difference caused by the difference in the absorption and reflection of the external ambient light between the area where the first section 21 is exposed and the area where no signal trace is disposed.
In addition, the high light-transmitting area BD may be a through hole penetrating through the entire thickness direction of the display module; or the blind holes may penetrate through part of the film layer, that is, only the film layer having a color or having a large influence on transmittance is removed and part of the transparent film layer is not removed or only reserved in order to meet the requirement of the camera on the transmittance of the high-transmittance area BD during the operation process of the camera without affecting the function of the device mounted therein, for example, when the camera is mounted in the high-transmittance area BD, which is not specifically limited in the present invention.
Based on the same inventive concept, the embodiment of the invention also provides a display device. The display device includes the display panel according to any embodiment of the present invention, and therefore, the display device provided in the embodiment of the present invention has the corresponding beneficial effects of the display panel provided in the embodiment of the present invention, and details are not repeated herein. For example, the display device may be an electronic device such as a mobile phone, a computer, a smart wearable device (e.g., a smart watch), and an in-vehicle display device, which is not limited in this embodiment of the present invention.
