The liquid crystal display panel comprises an array substrate, a color film substrate and liquid crystal filled between the array substrate and the color film substrate, wherein the array substrate and the color film substrate are oppositely arranged, blind holes are formed in the liquid crystal display panel for achieving shooting functions, and a camera is arranged below the display panel (for example, at the position of a mobile phone main board) corresponding to the blind holes. In general, a support column is disposed between the array substrate and the color film substrate in a display area of the liquid crystal display panel, so as to avoid deformation of the liquid crystal display panel when the liquid crystal display panel receives external pressure. In order to improve the photographing effect, the array substrate and the color film substrate in the blind hole area are not provided with support columns, and in the production process of the liquid crystal display panel, the array substrate and the color film substrate in the blind hole area are deformed and collapse, for example, refer to fig. 1, fig. 1 is a production process diagram of the liquid crystal display panel in the prior art, and the form change before and after thinning of the blind hole area is reflected. In the thinning process, the color film substrate and the array substrate are pressed, the pressing direction is shown in the direction indicated by an arrow in the figure, the array substrate in the blind hole area is not supported by the support columns, the bulge facing the color film substrate is formed on the array substrate in the blind hole area, and the bulge facing the array substrate is formed on the color film substrate. After thinning, the thicknesses of the array substrate and the color film substrate are thinned, and the protruding structures still exist, so that the thicknesses of the array substrate and the color film substrate in the blind hole area are larger than those of the array substrate and the color film substrate in the non-blind hole area. After the liquid crystal display panel is taken down from the thinning machine tool, the pressure applied to the array substrate and the color film substrate is eliminated, the protrusions of the array substrate and the color film substrate in the blind hole area rebound, so that the protrusions far away from the color film substrate are formed on the array substrate in the blind hole area, and the protrusions far away from the array substrate are formed on the color film substrate.
When the liquid crystal display panel forms a convex structure as shown in fig. 1 in the blind hole area, the convex structure forms a convex lens structure, when external light is transmitted from the color film substrate and the array substrate to the blind hole, the light will be converged in the blind hole, for example, please refer to fig. 2, fig. 2 shows a schematic diagram of the light path of the liquid crystal display panel in the blind hole area (including an ideal light path diagram and an actual light path diagram), and when the converged light in the blind hole is transmitted to the camera, the camera is most likely to be unable to normally image, so that the shooting capability of the camera is reduced, and the shooting effect of the liquid crystal display device is affected.
In the prior art, as the support column is not arranged at the position of the blind hole, the array substrate and the color film substrate in the blind hole area form a convex lens structure in the manufacturing process of the liquid crystal display panel, and original parallel light rays are distorted after passing through the convex lens, so that the camera cannot normally image, and the shooting capability of the camera is reduced.
In view of this, the present invention provides a display panel and a display device, in which a light adjuster is introduced into a first substrate and a second substrate of a photographing region, and light of the photographing region is adjusted by the light adjuster to form parallel light, which is beneficial to improving photographing capability of the display device in the photographing region.
Fig. 3 is a top view of a display panel provided in the implementation of the present application, fig. 4 is a cross-sectional view AA' of the display panel in fig. 3, fig. 5 is a schematic view of an optical path of a photographing region of the display panel corresponding to fig. 3, please refer to fig. 3 to 5, and a display panel 100 is provided, wherein the display panel 100 is provided with a display region 11 and a photographing region 12, and the display region 11 at least partially encloses the photographing region 12; the display panel 100 located in the photographing region 12 includes:
the liquid crystal display device comprises a first substrate 10, a second substrate 20 and a first liquid crystal 31 filled between the first substrate 10 and the second substrate 20, wherein the first substrate 10 and the second substrate 20 are oppositely arranged, a side of the first substrate 10 away from the second substrate 20 comprises a first protrusion 21, and a side of the second substrate 20 away from the first substrate 10 comprises a second protrusion 22;
the light adjuster 40 disposed between the first substrate 10 and the second substrate 20 forms parallel light after the light passes through the first protrusion 21, the light adjuster 40, and the second protrusion 22 in the photographing region 12.
In fig. 3, only one relative positional relationship diagram of the display area 11 and the photographing area 12 in the display panel 100 is shown, in this embodiment, the display area 11 surrounds the photographing area 12, and the photographing area 12 is illustrated as a circle, and in some other embodiments of the present application, the display area 11 may also partially surround the photographing area 12, and the shape of the photographing area 12 may also be set according to the actual situation, so that the screen ratio of the display panel can be effectively increased regardless of the positional relationship. In addition, the size and position of the photographing region 12 on the display panel 100 are also merely illustrative, and in some other embodiments of the present application, the photographing region 12 may be located at another position on the display panel 100, and the size of the photographing region 12 may be set according to the actual situation, which is not specifically limited in the present application.
Alternatively, the first substrate 10 includes a first substrate 91 and other film structures formed on the first substrate 91, the second substrate 20 includes a second substrate 92 and other film structures formed on the second substrate 92, the first bump 21 is formed on the first substrate 91, and the second bump 22 is formed on the second substrate 92.
Specifically, referring to fig. 3 to 5, in the display panel 100 provided in the present application, the display area is provided with the supporting columns 99, and since the photographing area 12 is not provided with the supporting columns, considering that the first substrate 10 and the second substrate 20 of the photographing area 12 are deformed during the production process of the display panel 100, the first substrate 10 is far from the second substrate 20 to form the first protrusion 21, the second substrate 20 is far from the first substrate 10 to form the second protrusion 22, and the first protrusion 21 and the second protrusion 22 form the convex lens structure. In the prior art, the existence of the convex lens structure can affect the normal transmission of light, so that the camera located in the shooting area 12 cannot normally image. And this application has introduced light regulator 40 between the first base plate 10 of shooting region 12 and second base plate 20, please see fig. 5, after the light of shooting region passes through first arch 21, light regulator 40 and second arch 22 in proper order, forms parallel light, so, adjusts the light that is distorted by convex lens structure among the prior art through light regulator 40, forms the required parallel light that satisfies the shooting to be favorable to promoting the shooting ability of display panel at shooting region.
Optionally, the light adjuster 40 comprises a first light adjuster 41 at a surface of the first substrate 10 facing the second substrate 20, and/or the light adjuster 40 comprises a second light adjuster 42 at a surface of the second substrate 20 facing the first substrate 10.
In an embodiment of the present invention, referring to fig. 6, fig. 6 is a schematic light path diagram of introducing a first light adjuster 41 into a photographing area 12, the light adjuster 40 includes the first light adjuster 41 located on a surface of the first substrate 10 facing the second substrate 20, the light path is changed after passing through a first protrusion 21 on the first substrate 10, so as to form a converging light, and the converging light is transmitted to the first light adjuster 41, the first light adjuster 41 processes the converging light to form a diffuse light with a certain extent, and after transmitting the diffuse light to a second protrusion 22, the second protrusion 22 converts the diffuse light into parallel light. In this way, after the first light adjuster 41 is introduced between the first substrate 10 and the second substrate 20 in the photographing region, the light incident from the first substrate 10 is emitted from the second substrate 20, and then parallel light satisfying the photographing condition is formed, thereby being beneficial to improving the photographing capability of the display panel 100 in the photographing region. It should be noted that, to form parallel light, the radian of the first light adjuster 41 may be flexibly adjusted according to the radian of the first protrusion 21 and the second protrusion 22. For example, in the present embodiment, the radian of the first light adjuster 41 is at most larger than the radian of the first protrusion and the second protrusion, so that the light has a slightly larger divergence angle than the incident angle when being incident on the first substrate when being transmitted from the first substrate to the liquid crystal layer.
In another embodiment of the present invention, referring to fig. 7, fig. 7 is a schematic view of an optical path of introducing a second light adjuster 42 into the photographing region 12, the light adjuster 40 includes the second light adjuster 42 located on a surface of the second substrate 20 facing the first substrate 10, the optical path of the light passing through the first protrusion 21 on the first substrate 10 is changed to form a converging light, the converging light is transmitted to the second light adjuster 42, the second light adjuster 42 processes the converging light to form a diffuse light with a certain degree, and the diffuse light is transmitted to the second protrusion 22, and then the diffuse light is converted into a parallel light by the second protrusion 22. In this way, after the first substrate 10 and the second substrate 20 in the photographing region are introduced into the second light adjuster 42, the light incident from the first substrate 10 is emitted from the second substrate 20, so as to form parallel light meeting the photographing condition, which is also beneficial to improving the photographing capability of the display panel 100 in the photographing region 12. It should be noted that, to form parallel light, the radian of the second light adjuster 42 may be flexibly adjusted according to the radian of the first protrusion 21 and the second protrusion 22. In this embodiment, the radian of the second light adjuster 42 is larger than the radian of the first protrusion and the radian of the second protrusion, so that the incident angle of the light on the second substrate is more divergent than the emergent angle on the first substrate.
In still another embodiment of the present invention, referring to fig. 5, fig. 5 is a schematic view of an optical path of a first light adjuster 41 and a second light adjuster 42 introduced into a photographing area 12 at the same time, wherein the light adjuster 40 includes the first light adjuster 41 located on a side surface of the first substrate 10 facing the second substrate 20 and the second light adjuster 42 located on a side of the second substrate 20 facing the first substrate 10, the optical path of the light is changed after passing through a first protrusion 21 on the first substrate 10, so as to form a converged light, and the converged light is transmitted to the first light adjuster 41, and the first light adjuster 41 adjusts the originally converged light and then transmits the converged light to the second light adjuster 42; the second light adjuster 42 diffuses and transmits the light to the second protrusion 22 to a certain extent, and the second protrusion 22 converts the light into parallel light and emits the parallel light, so that the light meets the shooting condition. In this way, the first light adjuster 41 and the second light adjuster 42 cooperate with the first protrusion 21 and the second protrusion 22 to form parallel light rays satisfying photographing conditions to enhance photographing capability of the display panel 100 in the photographing region 12.
In an alternative embodiment of the present invention, referring to fig. 4 and 5, the first substrate 10 includes a first organic film 51 disposed adjacent to the first liquid crystal 31, and the second substrate 20 includes a second organic film 52 disposed adjacent to the first liquid crystal 31;
when the light adjuster 40 includes both the first light adjuster 41 and the second light adjuster 42, the first light adjuster 41 is a first concave portion 83 formed at a surface of the first organic film 51 facing the second substrate 20, and the second light adjuster 42 is a second concave portion 84 formed at a surface of the second organic film 52 facing the first substrate 10.
Specifically, referring to fig. 4 and 5, the first substrate 10 includes a first organic film 51, the second substrate 20 includes a second organic film 52, the first organic film 51 and the second organic film 52 refer to film layers of the first substrate 10 and the second substrate 20 adjacent to the first liquid crystal 31, in this embodiment, the first light adjuster 41 is a first concave portion 83 formed by removing at least a portion of the first organic film 51, the second light adjuster 42 is a second concave portion 84 formed by removing at least a portion of the second organic film 52, the light passes through the first protrusion 21 on the first substrate 10 to form a concentrated light, and the concentrated light passes through the first concave portion 83 to be diffused to some extent and then is transmitted to the second concave portion 84; when passing through the second concave portion 84, the light is further diffused and then transmitted to the second protrusion 22, and the second protrusion 22 converts the diffused light into parallel light and emits the parallel light, thereby forming parallel light meeting the shooting requirement. In addition, when the first light adjuster 41 is embodied as the first concave portion 83 and the second light adjuster 42 is embodied as the second concave portion 84, the first concave portion 83 and the second concave portion 84 can be formed by processing the first organic film 51 and the second organic film 52 of the first substrate 10 and the second substrate 20, and the light adjustment can be realized without introducing a new film structure into the display panel 100, so that the production cost of the display panel 100 after introducing the light adjuster 40 is also reduced.
The radians of the first and second light adjusters 41 and 42 are adjusted according to the refractive index of the medium disposed between the first and second substrates 10 and 20, that is, the first and second organic films 51 and 52. Referring to fig. 5, when the refractive index of the medium between the first organic film 51 and the second organic film 52 is equal to that of the external air, the radian of the first light adjuster 41 is equal to that of the first protrusion, and the radian of the second light adjuster 42 is equal to that of the second protrusion 22. When the refractive index of the medium between the first organic film 51 and the second organic film 52 is smaller than that of the outside air, the radian of the first light adjuster 41 is larger than that of the first protrusion, and the radian of the second light adjuster 42 is larger than that of the second protrusion 22. When the refractive index of the medium between the first organic film 51 and the second organic film 52 is greater than that of the outside air, the radian of the first light adjuster 41 is smaller than that of the first protrusion, and the radian of the second light adjuster 42 is smaller than that of the second protrusion 22. As will be described later in other embodiments.
The following describes the formation of the display panel 100 provided in the present application by taking fig. 8 as an example, wherein fig. 8 is a production process diagram of the display panel 100 provided in the present application. When the first substrate 10 and the second substrate 20 are manufactured separately, the first concave portion 83 is formed as the first light adjuster 41 on the side of the first substrate 10 facing the second substrate 20, and the second concave portion 84 is formed as the second light adjuster 42 on the side of the second substrate 20 facing the first substrate 10. When the display panel 100 is not thinned after being packaged, that is, before thinning, a side of the first substrate 10 away from the second substrate 20 and a side of the second substrate 20 away from the first substrate 10 are in a flat structure; in thinning, the side of the first substrate 10 away from the second substrate 20 and the side of the second substrate 20 away from the first substrate 10 will be subjected to external force, and since the photographing region 12 is not provided with the support columns, the first substrate 10 of the photographing region 12 will be recessed toward the second substrate 20, and the second substrate 20 will be recessed toward the first substrate 10; after thinning, the thickness of the first substrate 10 of the photographing region 12 is greater than the thickness of the substrate of the display region 11, and the thickness of the second substrate 20 is greater than the thickness of the substrate of the display region 11; when the display panel 100 after the thinning is removed from the thinning machine, the first substrate 10 bulges to form the first protrusion 21 to the side away from the second substrate 20, the second substrate 20 bulges to form the second protrusion 22 to the side away from the first substrate 10, the first recess 83 on the side of the first substrate 10 facing the second substrate 20, and the second recess 84 on the side of the second substrate 20 facing the first substrate 10 remain in the photographing region 12 due to the disappearance of the external force originally applied to the first substrate 10 and the second substrate 20. The first concave portion 83 and the second concave portion 84 serve as the light adjuster 40, which can correct the light that is originally distorted, so that the photographing region 12 forms parallel light rays that satisfy photographing conditions, thereby facilitating the improvement of the photographing capability of the display panel 100 in the photographing region 12.
In an alternative embodiment of the present invention, fig. 9 is another schematic view of an optical path in which the first light adjuster 41 and the second light adjuster 42 are simultaneously introduced into the photographing region 12, the first substrate 10 includes a first organic film 51 disposed adjacent to the first liquid crystal 31, and the second substrate 20 includes a second organic film 52 disposed adjacent to the first liquid crystal 31;
when the light adjuster 40 includes both the first light adjuster 41 and the second light adjuster 42, the first light adjuster 41 is a first convex portion 81 formed on the surface of the first organic film 51 facing the second substrate 20, and the second light adjuster 42 is a second convex portion 82 formed on the surface of the second organic film 52 facing the first substrate 10.

Optionally, the first organic film and the second organic film are light-sensitive materials, when the light-sensitive materials are exposed, different exposure intensities can form material denaturation of different depths in the thickness direction, and different surface appearances can be formed after development. Considering that the main purpose of the photographing area of the display panel is to guide the external light to the corresponding camera, and the camera is generally in a circular structure, when the first light adjuster 41 is formed on the first display panel or the second light adjuster 42 is formed on the second substrate, the grating with a circular structure formed at the corresponding position of the photographing area 12 can be used as the first light adjuster 41 or the second light adjuster 42.

Specifically, referring to fig. 12, the present application makes a first electrode 61 on a surface of the first light adjuster 41 facing the second substrate 20, and the first electrode 61 is electrically connected to the first signal line 71; a second electrode 62 is formed on the surface of the second light adjuster 42 facing the first substrate 10, and the second electrode 62 is electrically connected to the second signal line 72. Wherein the first signal line 71 is for transmitting a first voltage signal to the first electrode 61 and the second signal line 72 is for transmitting a second voltage signal to the second electrode 62. When different voltages are applied to the first electrode 61 and the second electrode 62 through the first signal line 71 and the second signal line 72, a driving voltage for driving the first liquid crystal 31 to rotate is formed between the first electrode 61 and the second electrode 62, and the rotation angle of the first liquid crystal 31 can be controlled by controlling the voltage, so that the refractive index of the first liquid crystal in the thickness direction (the direction perpendicular to the light emitting surface of the display panel 100) is controlled, and thus, the light can be further corrected by introducing the first electrode 61 and the second electrode 62, and when the light regulator 40 is simply introduced for some uncontrollable reasons, the parallel light cannot be accurately output, the refractive index of the first liquid crystal 31 can be changed by providing an adjustable voltage to the first electrode 61 and the second electrode 62, so that the first liquid crystal 31 and the light regulator 40 act together to form the parallel light meeting the shooting requirement, and the parallel light can be formed more flexibly and controllably.
