Description

Liquid crystal display panel, liquid crystal display screen and electronic equipment
Technical Field
The application relates to the technical field of display, in particular to a liquid crystal display panel, a liquid crystal display screen and an electronic device.
Background
In order to increase the screen space ratio of the electronic device, as shown in fig. 1, a groove 101 is formed in the top of a liquid crystal display screen 100, and an optical device 102 such as a front camera or an infrared sensor is disposed in the groove 101. But the screen occupation of the electronic device is limited due to the presence of the slot 101.
Disclosure of Invention
The application provides a liquid crystal display panel for improving the screen occupation ratio of electronic equipment adopting the liquid crystal display panel. In addition, this application still provides corresponding liquid crystal display and electronic equipment.
In a first aspect, the present application provides a liquid crystal display panel. The liquid crystal display panel includes a liquid crystal layer and an array substrate, which are stacked in a first direction. It should be explained that the first direction refers to a transmission direction of light when the light is transmitted from the outside of the liquid crystal display panel to the inside of the liquid crystal display panel in the thickness direction of the liquid crystal display panel.
The array substrate includes a glass substrate and a device array layer stacked in a direction opposite to the first direction. The device array layer is provided with M through holes, wherein M is an integer greater than or equal to 1.
In this embodiment, since the array substrate is provided with one or more through holes, when light is transmitted from the outside of the liquid crystal display panel to the inside of the liquid crystal display panel through the through holes, the light is less blocked, and thus the transmittance is improved.
In the present application, the device array layer includes a gate-source electrode layer, an organic planarization layer, and a pixel electrode layer, which are stacked in a direction opposite to the first direction.
Further, a protective layer of the gate source electrode layer is arranged between the gate source electrode layer and the organic flat layer.
Furthermore, a protective layer of the pixel electrode layer is arranged on one side of the pixel electrode layer, which is far away from the organic flat layer.
In other words, the device array layer includes a gate source electrode layer and a protection layer thereof, an organic planarization layer, a pixel electrode layer and a protection layer thereof, and the gate source electrode layer and the protection layer thereof, the organic planarization layer, the pixel electrode layer and the protection layer thereof are stacked in a direction opposite to the first direction.
With reference to the first aspect, in a first possible implementation manner, the metal traces on the array substrate avoid the through holes disposed in the device array layer. By the scheme, the transmissivity of the through hole area of the liquid crystal display panel can be improved, and normal transmission of electric signals on the array substrate can be guaranteed. It should be explained that the through hole region of the liquid crystal display panel refers to a region corresponding to the through hole of the device array layer in the liquid crystal display panel.
With reference to the first aspect, in a second possible implementation manner, the liquid crystal display panel further includes a color film substrate, the color film substrate is located on a side of the liquid crystal layer away from the array substrate, and the color film substrate, the liquid crystal layer, and the array substrate are stacked along the first direction.
The color film substrate comprises a glass substrate and a color film layer which are stacked along the first direction. The color film layer is provided with N through holes, the N through holes of the color film layer and the N through holes in the M through holes of the device array layer are oppositely arranged in a one-to-one mode along the first direction, and N is an integer which is larger than or equal to 1 and smaller than or equal to M.
In this embodiment, since the color film layer is also provided with the through holes in the through hole region of the liquid crystal display panel, the transmittance of light passing through the through hole region of the liquid crystal display panel is further improved, or when light passes through the through hole region of the liquid crystal display panel, the transmittance is further improved.
Optionally, the aperture of the through hole of the color film layer is smaller than or equal to the aperture of the through hole of the device array layer. Put another way, the projection of the hole peripheral wall of the through hole of the color film layer along the first direction is located in the corresponding through hole area in the device array layer.
Optionally, the inner walls of the through holes of the color film layer are aligned with the inner walls of the corresponding through holes in the device array layer.
With reference to the second possible implementation manner of the first aspect, in a third possible implementation manner, the color film layer includes a light-shielding black matrix and a plurality of pixel color blocks. The light-shielding black matrix includes a plurality of light-shielding blocks. In other areas of the color film layer, the shading blocks and the pixel color blocking blocks are alternately arranged. The other areas of the color film layer are areas except the through holes in the color film layer.
By adopting the scheme, the light transmittance of the light transmission area of the liquid crystal display panel can be improved, and normal display of the display area of the liquid crystal display panel can be ensured. It is noted that the liquid crystal display panel includes a light-transmitting area and a display area. In general, in the liquid crystal display panel, all regions except for the light-transmitting region are display regions.
With reference to the first aspect or the first to third possible implementation manners of the first aspect, in a fourth possible implementation manner, one or more first support pillars isolated from each other are fixed to the light-transmitting region of the array substrate, and the first support pillars extend in a direction opposite to the first direction. The transparent area of the array substrate is positioned on one side of the array substrate facing the color film substrate, and the transparent area of the array substrate is positioned in the area where the through holes of the device array layer are positioned. In brief, the first support is rooted in the via region of the array substrate, and the free end extends toward the color filter substrate along a direction opposite to the one direction. By adopting the scheme, the surface of the liquid crystal display panel can be ensured to be flat.
Optionally, the first support pillar includes a gate-source electrode layer, an organic planarization layer, and a pixel electrode layer sequentially stacked in a direction opposite to the first direction.
Further, a protective layer of the gate source electrode layer is arranged between the gate source electrode layer and the organic flat layer in the first support column.
Furthermore, a protective layer of the pixel electrode layer is further arranged on one side of the pixel electrode layer, which is far away from the organic flat layer, in the first support column.
Therefore, it can also be said that the first support pillar includes a gate-source electrode layer and a protective layer thereof, an organic planarization layer, a pixel electrode layer and a protective layer thereof, which are sequentially stacked in a direction opposite to the first direction. The gate source electrode layer and the protective layer thereof refer to the gate source electrode layer and the protective layer covering the gate source electrode layer. Similarly, the pixel electrode layer and the protection layer thereof refer to the pixel electrode layer and the protection layer covering the pixel electrode layer.
As can be seen from the above, the first support column may comprise a plurality of different layers. In conjunction with the foregoing refinements to the device array layer, it can be appreciated that the device array layer includes a plurality of different layers. Then, when the first support pillar and the device array layer both include a plurality of different layers, the arrangement of the plurality of different layers in the first support pillar is the same as the arrangement of the plurality of different layers in the device array layer along the first direction.
With reference to the fourth possible implementation manner of the first aspect, in a fifth possible implementation manner, the liquid crystal display panel further includes a first liquid crystal alignment layer, where the first liquid crystal alignment layer is used to cover a surface of the array substrate facing the color filter substrate and an outer surface of the first support pillar. In the scheme, the surface of the array substrate facing the color film substrate and the outer surface of the first support column are regarded as an uneven surface, and then the first liquid crystal orientation layer is covered on the uneven surface, so that the complexity of a process for manufacturing the liquid crystal display panel can be reduced.
With reference to the fourth possible implementation manner of the first aspect, in a sixth possible implementation manner, one or more second support pillars that are isolated from each other are fixed to the light-transmitting region of the color filter substrate, and the number of the second support pillars is equal to that of the first support pillars. The second supporting column extends towards the array substrate along the first direction, and the second supporting column and the first supporting column are in one-to-one abutting joint. It should be explained that the light-transmitting area of the color film substrate is an area corresponding to the through hole of the color film layer in the color film substrate. Because the through holes of the color film layer and the through holes of the device array layer are opposite to each other in a one-to-one mode, the light transmission area of the color film substrate and the light transmission area of the array substrate are opposite to each other in a one-to-one mode. By adopting the scheme, the liquid crystal display panel can be ensured to be flat.
With reference to the sixth possible implementation manner of the first aspect, in a seventh possible implementation manner, the internal structure of the first support column is the same as the internal structure of the second support column. The scheme can reduce the complexity of the process for manufacturing the liquid crystal display panel.
With reference to the sixth or seventh possible implementation manner of the first aspect, in an eighth possible implementation manner, the liquid crystal display panel further includes a second liquid crystal alignment layer, and the second liquid crystal alignment layer covers a surface of the color filter substrate facing the array substrate and an outer surface of the second supporting pillar. Similarly to the above description about the first liquid crystal alignment layer, in this embodiment, the surface of the color filter substrate facing the array substrate and the outer surface of the second supporting pillar are regarded as an uneven surface, and then the second liquid crystal alignment layer is covered on the uneven surface. By adopting the scheme, the complexity of the process for manufacturing the liquid crystal display panel can be reduced.
With reference to the first aspect or any one of the first to eighth possible implementation manners of the first aspect, in a ninth possible implementation manner, the liquid crystal display panel further includes a lower polarizer located on a side of the array substrate facing away from the liquid crystal layer. The lower polarizer is provided with K through holes, the K through holes of the lower polarizer and the K through holes in the M through holes of the device array layer are arranged in a one-to-one opposite mode along the first direction, and K is an integer which is larger than or equal to 1 and smaller than or equal to M.
In this embodiment, since the lower polarizer is provided with the through hole at the position corresponding to the light-transmitting area of the liquid crystal display panel, when light penetrates the liquid crystal display panel from the light-transmitting area of the liquid crystal display panel, the light is blocked by the through hole and is further reduced, so that the lower polarizer has higher transmittance.
With reference to any one of the second to ninth possible implementation manners of the first aspect, the liquid crystal display panel further includes an upper polarizer, and the upper polarizer is located on a side of the color film substrate away from the liquid crystal layer. The upper polaroid is provided with R through holes, the R through holes of the upper polaroid and the R through holes in the M through holes of the device array layer are oppositely arranged in a one-to-one mode along the first direction, and R is an integer which is greater than or equal to 1 and smaller than or equal to M. Similar to the above-mentioned through holes formed in the lower polarizer, in this embodiment, the through holes formed in the upper polarizer can further improve the transmittance of light passing through the light-transmitting region of the liquid crystal display panel from the outside of the liquid crystal display panel.
In a second aspect, the present application provides a liquid crystal display panel including the liquid crystal display panel and the backlight module according to the first aspect or any one of the possible embodiments of the first aspect. The backlight module is provided with M through holes, and the M through holes of the backlight module and the M through holes of the device array layer are oppositely arranged in a one-to-one manner along the first direction.
It should be noted that the through hole located in the backlight module is used for placing the optical device. In this embodiment, since the optical device is disposed in the through hole of the backlight module, it is not necessary to cut a groove on the liquid crystal display panel and then dispose the optical device in the groove, as in the prior art. Therefore, compared with the prior art, the liquid crystal display screen display device has the advantages that the liquid crystal display screen display device does not need to be subjected to groove digging, so that the screen occupation ratio of the electronic equipment adopting the liquid crystal display screen display device can be improved, and further the full screen display is favorably realized.
In a third aspect, the present application further provides an electronic device comprising the liquid crystal display panel and M optical devices according to the second aspect. The M optical devices are placed in the M through holes of the backlight module one by one. Similar to the effect description regarding the liquid crystal display screen described above, in the present embodiment, the electronic apparatus can have a higher screen occupation ratio.
With reference to the third aspect, in a first possible implementation manner, the electronic device further includes a cover plate, the cover plate is located on a side of the liquid crystal display screen away from the inner cavity of the electronic device, and the cover plate and the liquid crystal display screen are bonded through an adhesive layer. This stability between can improving apron and liquid crystal display with this scheme.
Optionally, the Adhesive layer is made of transparent Optical Adhesive (OCA).
With reference to the first possible implementation manner of the third aspect, in a second possible implementation manner, when the adhesive layer is opaque, P through holes are provided in the adhesive layer. Along the first direction, the P through holes of the bonding layer and the P through holes in the M through holes of the backlight module are oppositely arranged in a one-to-one mode, and P is an integer which is larger than or equal to 1 and smaller than or equal to M.
By forming the holes in the adhesive layer, blocking of light by the hole regions of the adhesive layer can be eliminated, thereby further improving the light transmittance.

Detailed Description
Fig. 2 is a schematic structural diagram of an electronic device 100. The electronic device 100 may be any device with communication and storage capabilities, such as: the mobile phone, the tablet computer, the electronic reader, the notebook computer, the vehicle-mounted equipment or the wearable equipment and the like. The present application takes the electronic device 100 as a mobile phone as an example for explanation.
Specifically, the electronic device 100 includes a housing 200, optics 300, and a Liquid Crystal Display (LCD) 400. The case 200 may include a bezel and a rear cover, wherein the bezel is disposed around an edge of the rear cover. The liquid crystal display screen 400 covers the side of the bezel away from the back cover. The liquid crystal display 400 and the housing 200 together enclose an inner cavity of the electronic device 100. The optical device 300 is accommodated in the inner cavity. It is noted that the optical device 300 may be a camera module, an ambient light sensor, a proximity light sensor, or an optical fingerprint sensor.
As shown in fig. 3, fig. 3 is a cross-sectional view of the liquid crystal display assembly of the electronic device 100 shown in fig. 2 along the line a-a, and it is noted that the liquid crystal display assembly includes a cover 700 and a liquid crystal display panel 400, and an adhesive layer 800 disposed between the cover 700 and the liquid crystal display panel 400 for adhesion. It should be noted that, when viewed from the outer surface of the liquid crystal display panel 400, the liquid crystal display panel 400 includes a display region 902 and one or more light-transmitting regions 901 spaced apart from each other. Each of the light-transmissive regions 901 is surrounded by a display region 902. The display area 902 is used for displaying an image. The light-transmitting region 901 allows visible light to pass therethrough. It is noted that in the present application, a plurality means two or more.
It should be explained that both the light-transmitting area 901 of the liquid crystal display panel 400 and the display area 902 of the liquid crystal display panel 400 penetrate the liquid crystal display panel 400 in the thickness direction of the liquid crystal display panel 400. The liquid crystal display panel 400 is a plate-like structure divided into a light-transmitting area 901 and a display area 902. The light-transmitting area 901 of the liquid crystal display panel 400 and the display area 902 of the liquid crystal display panel 400 have a flat outer surface when viewed from the outer surface of the liquid crystal display panel 400, that is, when viewed from a plane. It should be understood that their respective thicknesses are the thickness of the liquid crystal display panel 400 (or, they are all through the liquid crystal display panel 400 in the thickness direction of the liquid crystal display panel 400) in a perspective view, and they are pieced together to form the liquid crystal display panel 400.
Specifically, the light-transmitting area 901 may be located on the top of the liquid crystal display 400, for example, the light-transmitting area 901 is located at the top left corner, the middle corner or the top right corner of the top of the liquid crystal display 400.
It should be noted that, as shown in fig. 2 and fig. 3, the electronic device 100 further includes a cover 700, and the cover 700 is located on a side of the liquid crystal display 400 away from the inner cavity of the electronic device 100. Referring to fig. 3, the lcd panel 400 may be adhered to the cover panel 700 by an adhesive layer 800. The Adhesive layer 800 may be transparent optical Adhesive (OCA) or opaque optical Adhesive. When the adhesive layer 800 uses a transparent optical adhesive, the adhesive layer 800 may be complete (or the adhesive layer 800 may be continuous), that is, the adhesive layer 800 is not provided with a through hole or hollowed out. When the adhesive layer 800 is made of opaque optical adhesive, a through hole is formed in the position of the adhesive layer 800 opposite to the light transmission area 901 of the liquid crystal display screen 400, or the position of the adhesive layer 800 opposite to the light transmission area 901 of the liquid crystal display screen 400 is hollowed out.
In the present application, the liquid crystal display panel 400 of the electronic device 100 has M light-transmitting regions 901, where M is an integer greater than or equal to 1. When M is an integer greater than or equal to 2, P through holes may be disposed on the adhesive layer 800, where P is an integer greater than or equal to 1 and less than or equal to M. It should be noted that each through hole of the adhesive layer 800 is directly opposite to one light-transmitting region 901 of the liquid crystal display panel 400 in the thickness direction of the liquid crystal display panel 400, that is, P through holes located in the adhesive layer 800 and P light-transmitting regions 901 located in the M light-transmitting regions 901 of the liquid crystal display panel 400 are directly opposite to each other in one-to-one manner in the thickness direction of the liquid crystal display panel 400. It should be noted that, when P is an integer smaller than M, for the other M-P light-transmitting regions 901 of the M light-transmitting regions 901 of the liquid crystal display panel 400, no through holes are opened in the adhesive layer 800, which are aligned one-to-one with the M light-transmitting regions in the thickness direction of the liquid crystal display panel 400.
Optionally, P is equal to M, that is, for each light-transmitting area 901, the adhesive layer 800 is provided with a corresponding through hole, so that it can be ensured that the adhesive layer 800 does not block the light passing through the light-transmitting area 901, in other words, the transmittance of the light passing through the light-transmitting area 901 from the outside of the liquid crystal display 400 can be improved.
Further, a material with high light transmittance may be filled in the through hole formed in the adhesive layer 800, so as to improve the light transmittance and ensure that the inside of the liquid crystal display panel 400 has good supporting capability.
It should be noted that in the embodiments corresponding to fig. 2 and fig. 3, the optical device 300 is used as a camera module. Of course, the optical device 300 may also be other devices that use visible light as the identification light, such as an ambient light sensor or an optical fingerprint sensor that identifies visible light.
As shown in fig. 4 (fig. 4 is a cross-sectional view of the liquid crystal display panel along the line a-a in the electronic device 100 shown in fig. 2), the liquid crystal display panel 400 includes a backlight module (backlight module)500 and a liquid crystal display panel 600. The backlight module 500 is disposed on a side of the lcd panel 600 close to the inner cavity of the electronic device. The backlight module 500 is used for providing a backlight source for the liquid crystal display panel 600.
Referring to fig. 3 and 4 together (fig. 4 is a schematic view of the liquid crystal display panel in fig. 3 in a detailed manner), the liquid crystal display panel 600 also has a light-transmitting area 601 corresponding to the light-transmitting area 901 of the liquid crystal display panel 400. In this application, the backlight module 500 is provided with one or more through holes 501 isolated from each other, and the number of the through holes 501 is the same as the number of the light-transmitting areas 901 of the liquid crystal display panel 400. It should be noted that the number of the light-transmitting regions 901 of the liquid crystal display panel 400 is equal to the number of the light-transmitting regions 601 of the liquid crystal display panel 600. Along the thickness direction of the lcd panel 400, the through holes 501 of the backlight module 500 are aligned with the light-transmitting regions 601 of the lcd panel 600.
One light-transmitting area 601 and the corresponding through hole 501 located on the liquid crystal display panel 600 in the thickness direction of the liquid crystal display panel 400 constitute one light-transmitting area 901 of the liquid crystal display panel 400. In other words, the light-transmissive area 601 of the lcd panel 600 is a portion of the light-transmissive area 901 of the lcd panel 400, and the light-transmissive area 901 of each lcd panel 400 includes one light-transmissive area 601 of the lcd panel 600.
Assuming that the surface of the liquid crystal display panel 400 is a first plane, it should be noted that the projection of the light-transmitting area 901 of each liquid crystal display panel 400 in the first plane coincides with the projection of the corresponding light-transmitting area 601 of the liquid crystal display panel 600 in the first plane. That is, the size of the projection of the light-transmitting area 901 of each liquid crystal display panel 400 in the first plane is the same as the size of the projection of the corresponding light-transmitting area 601 of the liquid crystal display panel 600 in the first plane.
Further, the liquid crystal display panel 600 also has a display area 602 surrounding the light-transmitting area 601, corresponding to the display area 902 of the liquid crystal display panel 400. Along the thickness direction of the liquid crystal display panel 400, the display area 602 of the liquid crystal display panel 600 and the non-through hole area corresponding to the display area 602 in the backlight module 500 together constitute a display area 902 of the liquid crystal display panel 400. The non-through hole region of the backlight assembly 500 refers to a region of the backlight assembly 500 except for the through hole. As is readily apparent from this description, the display area 602 of the liquid crystal display panel 600 is a part of the display area 902 of the liquid crystal display panel 400.
It is noted that the projection of the display area 902 of the lcd panel 400 in the first plane and the projection of the display area 602 of the lcd panel 600 in the first plane are coincident. That is, the size of the projection of the display area 902 of the liquid crystal display panel 400 in the first plane is the same as the size of the projection of the display area 602 of the liquid crystal display panel 600 in the first plane.
As shown in fig. 4, the optical device 300 is placed in the through hole 501 of the backlight assembly 500. When the optical device 300 is a camera module, since the transparent area 601 of the liquid crystal display panel 600 has a high transmittance, external ambient light can enter the camera module through the transparent area 601 of the liquid crystal display panel 600, and the intensity of the ambient light entering the camera module can meet the requirement of the camera module. When the optical device 300 is an infrared sensor, since the light-transmitting region 601 of the liquid crystal display panel 600 has a high transmittance, infrared light generated by the infrared sensor can be emitted through the light-transmitting region 601 of the liquid crystal display panel 600.
It should be noted that fig. 5 is a front view of the lcd panel 400. The liquid crystal display panel 400 includes one or more light-transmitting regions 901 and a display region 902, wherein the display region 902 surrounds each light-transmitting region 901. In an actual product, the area of the light-transmitting region 901 on the plane of the upper surface of the liquid crystal display panel 400 is small as shown in fig. 5, and therefore the display effect of the display region 902 is not affected.
Fig. 6 is a schematic view of a liquid crystal display panel 600 provided in the present application. The liquid crystal display panel 600 includes an upper polarizer 640, a color film substrate 610, a liquid crystal layer 630, an array substrate 620 and a lower polarizer 650.
Assuming that a direction in which light is perpendicularly incident from the outside of the liquid crystal display panel 600 to the inside of the liquid crystal display panel 600 is a first direction (or, assuming that a direction in which light is incident from the outside of the liquid crystal display panel 600 to the inside of the liquid crystal display panel 600 in the thickness direction of the liquid crystal display panel 600 is a first direction), the upper polarizer 640, the color filter substrate 610, the liquid crystal layer 630, the array substrate 620, and the lower polarizer 650 are sequentially stacked in the first direction. Note that, these 5 components (the upper polarizer, the color filter substrate, the liquid crystal layer, the array substrate, and the lower polarizer) are also stacked in this order from top to bottom. Among them, the liquid crystal layer 630 is the most important part to change the polarization state of light. In the present application, when the holder of the electronic device places the electronic device horizontally on the ground, the component located far from the ground is located above the component located near to the ground, and accordingly, the component located near to the ground is located below the component located far from the ground. The terms "upper" and "lower" may also be used elsewhere in this application, both with reference to the explanations herein for understanding, and the explanations will not be repeated where appropriate.
In the first embodiment of the present application, the array substrate 620 has M through holes 623, and as mentioned above, M is an integer greater than or equal to 1. It should be noted that the number of the through holes 623 formed in the array substrate 320 is the same as the number of the light-transmitting regions 901 included in the liquid crystal display panel 400 (or the light-transmitting regions 601 included in the liquid crystal display panel 600). In fact, the light-transmitting regions 901 on the liquid crystal display panel 400 are derived from the through holes 623 formed in the array substrate 620, and thus, the liquid crystal display panel 400 includes the light-transmitting regions 901 by the number of the through holes 623 formed in the array substrate 620. The area occupied by the through holes 623 of the array substrate 620 in the array substrate 620 is the through hole area of the array substrate 620, and due to the arrangement of the through holes 623, the blocking of light passing through the through hole area of the array substrate 620 is reduced, so the transmittance is increased.
In the present application, the array substrate 620 includes a glass substrate 621 and a device array layer 622 that are stacked in a direction opposite to the first direction. Further, the device array layer 622 includes a gate-source electrode layer 6221, an organic planarization layer 6222, and a pixel electrode layer 6223, which are stacked in a direction opposite to the first direction. A protective layer of the gate-source electrode layer 6221 may be provided between the gate-source electrode layer 6221 and the organic planarization layer 6222. And, the side of the pixel electrode layer 6223 away from the organic planarization layer 6222 may also have a protective layer for the pixel electrode layer 6223. Therefore, it can be said that the liquid crystal display device includes a gate-source electrode layer and its protective layer, an organic planarization layer, and a pixel electrode layer and its protective layer, which are stacked in a direction opposite to the first direction.
It should be noted that the metal traces on the array substrate 620 should be free from the through holes 623 formed on the device array layer 622. The present embodiment also ensures normal transmission of electrical signals on the array substrate 620 on the basis of improving the light transmittance.
In the second embodiment of the present application, the color film substrate 610 includes a glass substrate 611 and a color film layer 612 stacked along the first direction, and the color film layer 612 is provided with N through holes 613, where N is an integer greater than or equal to 1 and less than or equal to M. It is to be noted that, along the first direction, the N through holes 613 of the color film layer 612 and the N through holes 623 of the M through holes 623 of the device array layer 622 are disposed opposite to each other in a one-to-one manner. When N is an integer greater than or equal to 1 and less than M, the N vias 613 of the color film layer 612 and the N vias 623 of the device array layer 622 are aligned one-to-one along the first direction, and for the other M-N vias 623 of the device array layer 622, they are aligned with the non-via region of the color film layer 612 along the first direction. The area where the through hole 613 of the color film layer 612 is located is a through hole area of the color film layer 612, and other areas of the color film layer 612 besides the through hole area of the color film layer 612 may be referred to as non-through hole areas of the color film layer 612. The through hole 613 is formed in the color film layer 612, so that the light transmittance of the light-transmitting region 601 of the liquid crystal display panel 600 can be further improved.
Optionally, in the N through holes 613 of the color film layer 612, the hole wall of at least one through hole 613 is aligned with the hole wall of the corresponding through hole 623 of the device array layer 622.
Optionally, at least one via 613 of the N vias 613 of the color film layer 612 projects along the first direction to fall within a corresponding via region of the device array layer 622. It should be explained that the via area of the device array layer 622 refers to the area where the via 623 is located within the device array layer 622.
Specifically, the color film layer 612 includes a light-shielding black matrix 6121 and a plurality of pixel color blocks 6122, and the light-shielding black matrix 6121 includes a plurality of light-shielding blocks. The plurality of pixel color blocks 6122 include a red (R) color block, a green (G) color block, and a blue (B) color block. In other areas of the color film layer 612, the light-shielding blocks and the pixel color-resisting blocks are alternately arranged like black and white keys of a piano. It is easy to know that other areas of the color film layer 612 belong to the display area 602 of the liquid crystal display panel 600. In this embodiment, when the transmittance of the light-transmitting area 601 of the liquid crystal display panel 600 is improved, the display area 602 of the liquid crystal display panel 600 using the color film layer 612 can still normally display.
In the third embodiment of the present application, one or more first support pillars 680 are fixed to the light-transmitting region of the array substrate 620, and the first support pillars 680 extend in a direction opposite to the first direction. That is, the free end of the first support pillar 680 extends toward the color filter substrate 610. It should be noted that the light-transmitting region of the array substrate 620 is located on a side of the array substrate 620 facing the color filter substrate 610, and the light-transmitting region of the array substrate 620 refers to a region occupied by the through hole 623 located in the device array layer 622 in the array substrate 620.
Since the device array layer 622 is provided with the through hole 623, the first support column 680 fixed to the transparent region of the array substrate 620 is actually fixed to the glass substrate 621 corresponding to the through hole 623 of the device array layer 622.
Alternatively, the first support pillar 680 includes a gate-source electrode layer, an organic planarization layer, and a pixel electrode layer, which are stacked in a direction opposite to the first direction. A protective layer of the gate-source electrode layer may be further disposed between the gate-source electrode layer and the organic planarization layer in the first support pillar 680. Further, the side of the pixel electrode layer away from the organic planarization layer in the first support pillar may further have a protection layer of the pixel electrode layer. Therefore, it can also be said that the first support pillar 680 includes a gate-source electrode layer and its protective layer, an organic planarization layer, and a pixel electrode layer and its protective layer, which are stacked in a direction opposite to the first direction. It should be noted that, in this embodiment, the gate-source electrode layer and the protective layer thereof refer to the gate-source electrode layer and the protective layer covering the gate-source electrode layer. Similarly, the pixel electrode layer and the protective layer thereof refer to the pixel electrode layer and the protective layer covering the pixel electrode layer.
As described previously, the device array layer 622 includes a number of different layers. Alternatively, the arrangement of the plurality of different layers included in the first support pillar 680 and the arrangement of the plurality of different layers included in the device array layer 622 are the same. When the device array layer 622 is fabricated, corresponding layers are formed layer by layer in a direction opposite to the first direction, and when each layer is formed, other portions except for a portion corresponding to the first support column 680 and a portion corresponding to the device array layer 622 are etched by an etching process, so that the first support column 680 and the device array layer 622 are finally formed at the same time. In this way, the first support pillars 680 and the device array layer 622 are integrated, so the process complexity is low and the manufacturing efficiency is high.
In a fourth embodiment of the present disclosure, the liquid crystal display panel 600 may further include a first liquid crystal alignment layer 690, where the first liquid crystal alignment layer 690 covers the surface of the array substrate 620 facing the color filter substrate 610 and the outer surface of the first support pillar 680, and is in direct contact with the liquid crystal of the liquid crystal layer 630. In the present application, the liquid crystal cell includes a liquid crystal layer 630 and a first liquid crystal alignment layer 690. The liquid crystal orientation layer is a thin layer material of which the surface of a substrate of the liquid crystal box is directly contacted with liquid crystal, and the liquid crystal orientation layer has the function of enabling liquid crystal molecules in the liquid crystal layer to be arranged according to a certain direction and angle. The first liquid crystal alignment layer 690 refers to a liquid crystal alignment layer located at a specific position.
In a fifth embodiment of the present disclosure, one or more second supporting pillars 660 isolated from each other are fixed to the light-transmitting region of the color filter substrate 610. The free end of the second support post 600 extends toward the array substrate 620, or the free end of the second support post 660 extends in the first direction. It is noted that the number of the second supporting columns 660 is equal to the number of the first supporting columns 680, and the second supporting columns 660 are in one-to-one abutting connection with the first supporting columns 680. It should be noted that the light-transmitting area of the color filter substrate 610 refers to an area occupied by the through hole 613 of the color filter layer 612 in the color filter substrate 610. Further, the light-transmitting area of the color filter substrate 610 faces the array substrate 620. As is known, the color filter layer 612 is provided with a through hole 613, so that the light-transmitting area of the color filter substrate 610 is located on the glass substrate 611 in the color filter substrate 610, specifically, the glass substrate 611 in the color filter substrate 610 corresponds to the area of the through hole 613 of the color filter layer 612.
Alternatively, as shown in fig. 7, the internal structure of the first support column 680 is the same as the internal structure of the second support column 660.
In order to improve the transmittance of the light-transmitting region 601 of the liquid crystal display panel 600, the density of the first support columns 680 needs to be reduced, or the pitch between two adjacent first support columns 680 needs to be increased. Illustratively, the spacing between two adjacent first support posts 680 is greater than 200 microns.
Further, the color filter substrate 610 further includes an organic planarization layer, and along the first direction, the glass substrate 611 of the color filter substrate 610, the color filter layer 612, and the organic planarization layer of the color filter substrate 610 are stacked.
In the sixth embodiment of the present application, the liquid crystal display panel 600 further includes a second liquid crystal alignment layer 670, and the second liquid crystal alignment layer 670 covers the surface of the color film substrate 610 facing the array substrate 620 and the outer surface of the second supporting pillar 660. In this embodiment, the surface of the color filter substrate 610 facing the array substrate 620 and the outer surface of the second supporting pillars 660 are regarded as an uneven (or curved) surface, and the second liquid crystal alignment layer 670 covers the uneven surface.
In a seventh embodiment of the present disclosure, the liquid crystal display panel 600 further includes an upper polarizer 640, and the upper polarizer 640 is located on a side of the color film substrate 610 departing from the liquid crystal layer 630. It can be seen that the upper polarizer 640 is adhered to the cover plate 700 by the adhesive layer 800. It should be noted that the polarizer means an optical element that can change natural light into polarized light. It is to be noted that the upper polarizer 640 is provided with R through holes, where R is an integer greater than or equal to 1 and less than or equal to M. When R is an integer less than M, R through holes of the upper polarizer 640 are aligned with R through holes of the device array layer 622 one-to-one along the first direction. It is easy to know that, for the other M-R through holes of the device array layer 622, the portions other than the through holes of the upper polarizer 640 are directly opposite to them along the first direction, that is, the through holes directly opposite to them along the first direction are not provided on the upper polarizer 640.
In the eighth embodiment of the present application, the liquid crystal display panel 600 provided by the present application may further include a lower polarizer 650, and the lower polarizer 650 is located on a side of the array substrate 620 facing away from the liquid crystal layer 630. It is to be noted that the lower polarizer 650 is provided with K through holes, where K is an integer greater than or equal to 1 and less than or equal to M. When K is an integer smaller than M, K vias of the lower polarizer 650 and K vias of the M vias of the device array layer 622 are directly aligned in one-to-one manner along the first direction. For the other M-K through holes of the device array layer 622, facing them in the first direction are portions other than the through holes of the lower polarizer 650.
Further, a transparent material may be filled in the through hole of the upper polarizer 640 or the through hole of the lower polarizer 650, so as to improve the light transmittance of the light-transmitting area 601 of the liquid crystal display panel 600 and enable the liquid crystal display 400 using the liquid crystal display panel 600 to have a more stable internal structure.
In the present application, a light shielding region may be further provided between the light-transmitting region 601 of the liquid crystal display panel 600 and the display region 602 of the liquid crystal display panel 600, and the light shielding region is used for shielding visible light and preventing the visible light from entering the display region 602 of the liquid crystal display panel 600.
