Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
As mentioned in the background art, the conventional camera of the display device has poor imaging effect, and the inventor finds that the problem is caused by that at present, light in a hole digging area of a display area in the display device is reflected by a multilayer glass interface, and the like, so that the transmittance of the light is low, and the imaging effect of the camera is affected.
In view of the above problem, the present embodiment provides a display device, and fig. 1 is a schematic diagram of the display device provided in the present embodiment, and referring to fig. 1, the display device includes: a transparent region 10 and a display region 20 at least partially surrounding the transparent region 10; the display device further includes: a first substrate 30 and a second substrate 40 disposed opposite to each other, and a first functional layer 50 disposed between the first substrate 30 and the second substrate 40; the first functional layer 50 is provided with a first through hole 51 in the transparent region 10; a first antireflection material layer 60 is disposed in the first through hole 51, and the first antireflection material layer 60 is used to increase the transmittance of light in the transparent region.
The display device may be an Organic Light Emitting Diode (OLED) display device, and the transparent area 10 may be used to set an optical sensor such as a camera. The first substrate 30 may be a substrate base substrate, the first functional layer 50 may include a display functional layer and a driving circuit layer, and the second substrate 40 may be a package substrate. In another alternative embodiment, the first substrate 30 may be a package cover, the first functional layer 50 may be a polarizer or a touch layer, and the second substrate 40 may be a cover. The first substrate 30 and the second substrate 40 are both transparent substrates, and may be both glass substrates by way of example.
Specifically, first antireflective material layer 60 may be made of a material having optical characteristics the same as or similar to those of first substrate 30 and second substrate 40, and exemplary first antireflective material layer 60 may be made of the same material as that of first substrate 30 or second substrate 40, and the first antireflective material layer may be disposed to fill the gap between first substrate 30 and second substrate 40. When the materials used for the first anti-reflection material layer 60 and the first substrate 30 are the same, optionally, the first anti-reflection material layer 60 and the first substrate 30 may be integrally formed, and a reflection interface, which is a surface of the first substrate 30 adjacent to the second substrate 40, is reduced in the first through hole 51, compared with the prior art, so that light reflection is reduced, and light transmittance is improved. When the materials used for the first anti-reflection material layer 60 and the second substrate 40 are the same, optionally, the first anti-reflection material layer 60 and the second substrate 40 may be integrally formed, and a reflection interface, which is a surface of the second substrate 30 adjacent to the first substrate 30, is reduced in the first through hole 51, compared with the prior art, so that light reflection is reduced, and light transmittance is improved. When the materials used for the first substrate 30, the second substrate 40, and the first antireflection material layer 60 are the same, the reflection interfaces in the first through holes 51 are eliminated, and there is no interface reflection in the first through holes 51, which improves the light transmittance. For example, the first antireflection material layer 60, the first substrate 30, and the second substrate 40 are made of glass, and the first antireflection material layer 60 may be formed using glass paste or glass frit, so that a glass-vacuum interface in the first through hole 51 is eliminated, an interface reflection effect is eliminated, and a light transmittance is improved.
In addition, first antireflection material layer 60 may be formed using magnesium fluoride or the like. In this case, in the transparent region 10, a first antireflection material layer 60 may be disposed on the surface of the first substrate 30 adjacent to the second substrate 40, and a first antireflection material layer 60 may be disposed on the surface of the second substrate 40 adjacent to the first substrate 30, respectively, so as to increase the interface transmittance of the first substrate 30 and the second substrate 40. A first antireflection material layer 60 may also be provided, the first antireflection material layer 60 fills the gap between the first substrate 30 and the second substrate 40, and the thickness of the first substrate 30 or the second substrate 40 at the first through hole 51 is adjusted to adjust the distance between the opposite surfaces of the first substrate 30 and the second substrate 40 at the first through hole 51, so that the thickness of the first antireflection material layer 60 meets the antireflection requirement.
In addition, the first antireflection material layer 60 may also be made of optical adhesive or the like, and the inventor finds through simulation experiments that filling the optical adhesive at the first through hole 51 may also improve the light transmittance of the transparent region 10.
In this embodiment, the first antireflection material layer 60 is disposed in the first through hole 51, so that the reflection of light by the interface between the first substrate 30 and the second substrate 40 in the first through hole 51 is reduced, the light transmittance of the transparent region 10 is improved, and the imaging effect of the camera is improved.
In addition, when the material used for the first anti-reflection material layer 60 is glass powder or glass paste, the process for preparing the first anti-reflection material layer 60 may be to fill the glass powder or glass paste into the first through hole 51, align the first substrate 30 and the second substrate 40, and then cure the first anti-reflection material layer 60. When the first anti-reflection material layer 60 is made of magnesium fluoride, the first anti-reflection material layer 60 may be formed by a sol-gel method, specifically, the magnesium fluoride material is made into sol with a certain viscosity, the sol is coated on the surface of the first substrate 30 or the second substrate 40, and the sol is heated and decomposed at a low temperature to form the first anti-reflection material layer 60.
Fig. 2 is a schematic view of another display device provided in this embodiment, and optionally, referring to fig. 2, in the transparent region 10, a first protruding portion 41 is disposed on a surface of the second substrate 40 adjacent to the first substrate 30, and the first protruding portion 41 extends into the first through hole 51.
Specifically, the height of first protrusions 41 may be set as needed according to the thickness of first antireflection material layer 60. Forming first antireflection material layer 60 requires filling antireflection material in first through hole 51, and if first antireflection material layer 60 has a large thickness and is filled with a large amount of material, the antireflection material may overflow display region 20 and contaminate devices in display region 20, thereby affecting the display effect. By arranging the first protruding portion 41 on the surface of the second substrate 40, the first anti-reflection material layer 60 may have a smaller thickness and may be made of less anti-reflection material, so that the anti-reflection material is prevented from overflowing to the display area 20, and the display area 20 is ensured to have a better display effect.
Fig. 3 is a schematic view of another display device provided in this embodiment, and optionally, referring to fig. 5, in the transparent region 10, a second protrusion 31 is disposed on a surface of the first substrate 30 adjacent to the second substrate 40, and the second protrusion 31 extends into the first through hole 51. With such an arrangement, the first anti-reflection material layer 60 may also have a smaller thickness and may be made of less anti-reflection material, so that the anti-reflection material is better prevented from overflowing to the display area 20, and the display area 20 is ensured to have a better display effect.
In addition, referring to fig. 2 and 3, in order to further prevent the display effect of display region 20 from being affected during the preparation of first antireflection material layer 60, an anti-overflow structure 70 may be disposed on the surface of first substrate 30 and/or second substrate 40 located in transparent region 10, where anti-overflow structure 70 prevents first antireflection material layer 60 from spreading toward display region 20 during the formation process.
Specifically, the spill prevention structure 70 may be a groove 71. As shown in fig. 2, a groove 71 may be formed on the surface of the first substrate 30, when the first anti-reflection material layer 60 is formed, an anti-reflection material may be added to the surface of the first substrate 30, and the second substrate 40 is placed and then cured, and the groove 71 may be formed on the surface of the first substrate 30, so as to slow down the propagation of the anti-reflection material to a gap between the first substrate 30 and the first functional layer 50, prevent the anti-reflection material from contaminating devices in the display region 20, and ensure that the display region 20 has a better display effect.
In addition, referring to fig. 3, a groove 71 may be further disposed on the surface of the second substrate 40, when the first anti-reflection material layer 60 is formed, an anti-reflection material may be added to the surface of the second substrate 40 first, and the first substrate 30 is placed and then cured, and the groove 71 disposed on the surface of the second substrate 40 may slow down the propagation of the anti-reflection material to a gap between the second substrate 40 and the first functional layer 50, so as to prevent the anti-reflection material from contaminating devices in the display area 20, and ensure that the display area 20 has a better display effect.
In addition, referring to fig. 4 (fig. 4 is a schematic view of another display device provided in this embodiment), a first groove 701 may be formed on the surface of first substrate 30, a second groove 702 may be formed on the surface of second substrate 40, and an anti-reflection material may be added to the surface of first substrate 30 or second substrate 40 when forming first anti-reflection material layer 60. When the amount of the anti-reflection material is large, after the first substrate 30 and the second substrate 40 are attached to each other, the anti-reflection material may spread to a gap between the first substrate 30 and the first functional layer 50 or a gap between the second substrate 40 and the first functional layer 50, and the grooves are formed in the surfaces of the first substrate 30 and the second substrate 40, so that the spread of the anti-reflection material can be slowed down, the anti-reflection material is prevented from polluting devices in the display area 20, and the display area 20 is ensured to have a good display effect.
It should be noted that fig. 4 only illustrates the first groove and the second groove as different shapes of grooves, and is not a limitation of the present invention, and in other embodiments, the first groove and the second groove may be provided as needed, and the first groove and the second groove may be provided as the same shape and the same size of grooves.
In addition, the size and the depth of the groove can be set as required, as long as the overflow of the anti-reflection material can be slowed down, and the strength of the first substrate and the second substrate is not affected, and the embodiment is not particularly limited. Several possible forms of the grooves are described below in connection with specific embodiments.
Optionally, a vertical projection of the first through hole on the first substrate completely overlaps with a vertical projection of the groove on the first substrate.
For example, referring to fig. 2, when the groove 71 is formed on the surface of the first substrate 30, the portion of the first substrate 30 located in the transparent region 10 is thinned to form the groove 71. When the first anti-reflection material layer 60 is prepared, the anti-reflection materials may be all disposed in the groove 71, and when the thickness of the first light-transmitting material layer 60 is small, the groove 71 may contain all or most of the anti-reflection materials, so that the spreading speed of the anti-reflection materials to the display region 20 may be effectively avoided. When the thickness of the first light-transmitting material layer 60 is larger, the sidewall of the groove 71 may also play a certain role in blocking the anti-reflection material, so as to slow down the propagation of the anti-reflection material to the display area 20.
In addition, when the groove is formed in the second substrate, the part of the second substrate, which is positioned in the transparent area, is thinned to form the groove, so that the spreading speed of the anti-reflection material to the display area can be effectively avoided.
Fig. 5 is a schematic view of still another display device provided in the present embodiment, and alternatively, referring to fig. 5, the groove 71 includes at least two annular sub-grooves 711. Each annular sub-groove 711 has a certain buffering effect on the anti-reflection materials, and at least two annular sub-grooves 711 can better slow down the spreading speed of the anti-reflection materials to the display area 20, so that the anti-reflection materials are prevented from polluting devices in the display area 20 to influence the display effect.
Alternatively, with continued reference to fig. 5, the groove 71 is disposed on the surface of the first substrate 30, the cross-section of the first through hole 51 parallel to the thickness direction of the display device is trapezoidal, and the larger bottom of the trapezoid is adjacent to the first substrate 30.
Specifically, when forming the first anti-reflection material layer 60, the anti-reflection material may be disposed on the surface of the first substrate 30, and the bottom with the larger trapezoid is disposed adjacent to the first substrate 30, so that the inclination angle of the sidewall of the first through hole 51 is not favorable for the adhesion of the anti-reflection material, and further the anti-reflection material is prevented from spreading toward the display area 20.
In addition, the groove is arranged on the surface of the second substrate, and the shape of the section of the first through hole parallel to the thickness direction of the display device is also trapezoidal, and the larger bottom of the trapezoid is adjacent to the second substrate. At this time, when the first anti-reflection material layer is formed, the anti-reflection material may be disposed on the surface of the second substrate, and the bottom with the larger trapezoid is disposed adjacent to the second substrate, so that the inclination angle of the sidewall of the first through hole is not favorable for the adhesion of the anti-reflection material, and further the anti-reflection material is prevented from spreading to the display region.
Fig. 6 is a schematic view of still another display device provided in the present embodiment, and alternatively, referring to fig. 6, the overflow preventing structure 70 includes at least one annular dam 72, and the annular dam 72 that is most adjacent to the inner wall of the first through-hole 51 is in contact with the inner wall of the first through-hole 51.
Specifically, by providing the annular bank 72, the first antireflection material layer 60 can be well prevented from spreading toward the display region 20 when formed.
Wherein the annular bank 72 can be made of the same material as the first substrate 30 or the second substrate 40, and the annular bank 72 can be integrally formed with the first substrate 30 or the second substrate 40, for example, when the first substrate 30 is formed, a glass substrate with a larger thickness can be used, and the first substrate 30 with the annular bank 72 can be formed by etching.
In the case where the first substrate 30 is a base substrate, the bank 72 may be formed using an insulating layer in the display function layer when the display function layer is formed on the surface of the first substrate 30. Illustratively, the display function layer includes a pixel defining layer and insulating layers such as supporting pillars, where the pixel defining layer is used to define a plurality of pixel units, the supporting pillars are disposed on a surface of the pixel defining layer away from the first substrate 30, and the supporting pillars are used to support a mask used for evaporating the pixel units. The annular bank 72 may be formed in the same process step as the pixel defining layer and/or the support posts.
In addition, the distance of the ring bank 72 from the surface of the first substrate 30 in the thickness direction of the display device may be equal to the distance of the support columns from the surface of the first substrate 30 in the thickness direction of the display device from the first substrate 30.
Fig. 7 is a schematic diagram of another display device provided in this embodiment, and referring to fig. 7, the display device further includes: a third substrate 80, wherein the third substrate 80 is disposed on a side of the second substrate 40 away from the first substrate 30, a second functional layer 90 is disposed between the third substrate 80 and the second substrate 40, and the second functional layer 90 is disposed with a second through hole 91 in the transparent region 10; the second through hole 91 is filled with a second anti-reflection material layer 100, and the second anti-reflection material layer 100 is used for increasing the transmittance of light in the transparent region.
Specifically, the first substrate 30 may be a substrate base substrate, the second substrate 40 may be a package cover plate, the first functional layer 50 may include a driving circuit layer and a light emitting functional layer, the third substrate 80 may be a cover plate, and the second functional layer 90 may include a polarizer and/or a touch layer.
In this embodiment, the second anti-reflection material layer 100 is disposed in the second through hole 91, so that the reflection of light by the interface between the third substrate 80 and the second substrate 40 in the second through hole 91 is reduced, the transmittance of light at the transparent region 10 is improved, and the imaging effect of the camera is improved.
It is to be noted that the second antireflection material layer may be formed using the same material as the first antireflection material layer. The surface of the second substrate and/or the third substrate, which is located in the transparent area, may also be provided with a first anti-overflow structure, which prevents the second anti-reflection material layer from spreading toward the display area during formation.
