The existing display panel has the problem that the product quality of the display panel is affected due to the fact that the two side substrates are prone to being sunken inwards due to the fact that the supporting force of a supporting object between the two side substrates is insufficient in the blind hole area. Based on this, the present application provides a display panel and a display device.
Referring to fig. 1 to 6, the display panel 100 includes a blind hole region 101 and a non-blind hole region 102 located at the periphery of the blind hole region 101.
The display panel 100 includes a first substrate 103, a second substrate 104 disposed corresponding to the first substrate 103, and a supporting member 105 located between the first substrate 103 and the second substrate 104, where the supporting member 105 includes a first support 106 located in the blind hole region 101 and a second support 107 located in the non-blind hole region 102, and a thickness of the first support 106 is greater than a thickness of the second support 107.
Through the arrangement that the thickness of the first support 106 is greater than that of the second support 107, the support force is provided for the two side substrates of the display panel 100 in the blind hole area 101, the two side substrates of the display panel 100 are prevented from being sunken in the blind hole area 101, and the product quality of the display panel 100 is improved.
The technical solution of the present application will now be described with reference to specific embodiments.
Example one
Referring to fig. 2, in the present embodiment, the distribution density of the first supporting objects 106 is gradually increased in the direction from the non-blind via region 102 to the blind via region 101.
Alternatively, the elastic modulus of the first support 106 gradually increases in the direction from the non-blind hole region 102 to the blind hole region 101.
When the supporting force of the supporting member 105 in the blind hole region 101 is insufficient, the degree of inward recess of the two side substrates of the display panel 100 gradually increases along the direction from the non-blind hole region 102 to the blind hole region 101. Therefore, by gradually increasing the distribution density of the first support 106 or gradually increasing the elastic modulus of the first support 106 in this direction, it is beneficial to provide a supporting force for the substrates on both sides of the display panel 100 in the blind hole region 101, and at the same time, provide a more sufficient supporting force at a position where a recess is more likely to occur, and it is beneficial to reduce the possibility of a recess existing in the blind hole region 101, and improve the product quality of the display panel 100.
In this embodiment, the first substrate 103 may be an array substrate, a COA (color filter on array) substrate, or other types of substrates, and is not limited herein.
In this embodiment, the second substrate 104 may be a color filter substrate or another substrate disposed corresponding to the first substrate 103, and is not limited specifically herein.
In this embodiment, the shape of the blind hole area 101 may be a circle, a square, or other regular or irregular shape, and is not limited herein. The blind hole region 101 is used for transmitting light to the optical element through the display panel 100.
In this embodiment, the material of the first support 106 may be a light-transmitting material or a non-light-transmitting material, and is not limited specifically herein.
When the first support 106 is made of a light-transmitting material, the first support 106 is distributed at any position in the blind hole region 101, which is beneficial to providing enough support force for the two side substrates at any position of the first support 106 in the blind hole region 101, so that the inward depression of the two side substrates of the display panel 100 at any position of the blind hole region 101 can be effectively avoided, and the product quality of the display panel 100 is improved.
When the material of the first support 106 is a non-light-transmitting material, the blind hole region 101 includes a first sub-blind hole region and a second sub-blind hole region disposed around the first sub-blind hole region. The first sub-blind hole region is used for allowing light to pass through the display panel 100 to reach an optical element. At this time, the first support 106 is located in the second sub-blind hole region, and the number of the first sub-blind hole regions may be greater than or equal to 1.
When the number of the first sub-blind hole regions is greater than 1, the first sub-blind hole regions may be dispersed in the blind hole region, which is favorable for reducing the area of a single first sub-blind hole region while allowing enough light to pass through the display panel 100 to reach an optical element, and is favorable for avoiding concentration of a region without the first support 106 in the blind hole region, so that the first support 106 provides enough support force for the substrates on both sides at any position in the blind hole region 101, and the product quality of the display panel 100 is improved.
In this embodiment, in the direction from the non-blind hole region 102 to the blind hole region 101, the distribution density of the first supporting object 106 is gradually increased or the elastic modulus of the first supporting object 106 is gradually increased, which is beneficial to providing a stronger supporting force for a place where the blind hole region 101 is more prone to be recessed, so that the supporting effect of the first supporting object 106 is improved, and the product quality of the display panel 100 is improved.
Example two
Referring to fig. 3, the present embodiment is the same as or similar to the first embodiment, except that:
the first support 106 is continuously disposed along the periphery of the blind hole region 101 to separate the organic material in the non-blind hole region 102 from the blind hole region 101.
In this embodiment, in a direction from the non-blind hole region 102 to the blind hole region 101, the number of the first supports 106 may be greater than or equal to 2.
In this embodiment, in a direction from the non-blind via region 102 to the blind via region 101, the number of the first supports 106 may be 2N, where N is an integer greater than or equal to 1.
In this embodiment, the organic material may also be a liquid crystal layer and the alignment layer between the first substrate 103 and the second substrate 104.
When the first support 106 is continuously disposed along the periphery of the blind hole region 101, the flow of the alignment liquid for forming the alignment layer into the blind hole region 101 is blocked, and the formation of the liquid crystal layer avoids the blind hole region 101, which is beneficial to further improving the light transmittance of the blind hole region 101, improving the light receiving amount of the optical element, further improving the performances such as the resolution of the camera, and improving the product quality of the display panel 100.
In this embodiment, the organic material may be only an alignment layer on the first substrate 103 and/or the second substrate 104.
By continuously arranging the first support 106 along the periphery of the blind hole region 101, in the manufacturing process of the display panel 100, the flow of the alignment liquid for forming the alignment layer into the blind hole region 101 is blocked, and the influence on the light reaching the optical element through the blind hole region 101 due to the formation of the alignment layer in the blind hole region 101, and further the influence on the light quantity received by the optical element and the product quality of the display panel 100 are avoided.
In this embodiment, the display panel 100 further includes a liquid crystal layer disposed on the same layer as the supporting member 105, the liquid crystal layer includes a first liquid crystal region located in the blind hole region 101 and a second liquid crystal region located in the non-blind hole region 102, and a thickness of a liquid crystal material in the first liquid crystal region is greater than a thickness of a liquid crystal material in the second liquid crystal region.
In this embodiment, the liquid crystal material in the first liquid crystal region may fill up the space between the first substrate 103 and the second substrate 104 except the first support 106.
By filling the space between the first substrate 103 and the second substrate 104 except the first supporting object 106 with the liquid crystal material in the first liquid crystal region, the liquid crystal material in the first liquid crystal region also provides a supporting force for the substrates on both sides of the display panel 100, shares the pressure applied to the first supporting object 106, prolongs the service life of the first supporting object 106, is beneficial to further enhancing the supporting force applied to the substrates on both sides of the display panel 100 in the blind hole region 101, avoids the substrate on both sides of the display panel 100 from sinking in the blind hole region 101, and improves the product quality of the display panel 100.
In this embodiment, at low temperature, the degree of shrinkage of the first support 106 may be less than the degree of shrinkage of the liquid crystal material in the first liquid crystal region.
When the shrinkage degree of the first support 106 is smaller than the shrinkage degree of the liquid crystal material in the first liquid crystal region, when the liquid crystal material in the first liquid crystal region loses the supporting force on the substrates at the two sides of the display panel 100 in the blind hole region 101, the supporting force is continuously provided for the substrates at the two sides of the display panel 100, so that the phenomenon that the substrates at the two sides are obviously sunken inwards due to the shrinkage of the liquid crystal material at low temperature is avoided, and the product quality of the display panel 100 is improved.
In this embodiment, the first support 106 further includes a first opening.
Wherein, in a direction from the non-blind via region 102 to the blind via region 101, a distance between the first opening and the first substrate 103 or the second substrate 104 gradually increases.
In this embodiment, the first opening is used for filling the liquid crystal material in the first liquid crystal region.
In this embodiment, when there is only one turn of the first support 106 continuously disposed along the periphery of the blind via region 101, the distance between the side of the first opening close to the non-blind via region 102 and the first substrate 103 or the second substrate 104 is smaller than the distance 104 between the side of the first opening far from the non-blind via region 102 and the first substrate 103 or the second substrate.
When the first support 106 is continuously disposed along the periphery of the blind hole region 101 more than one turn, in the direction from the non-blind hole region 102 to the blind hole region 101, the distance between the first opening of the first support 106 close to the non-blind hole region 102 side and the first substrate 103 or the second substrate 104 is smaller than the distance between the first opening of the first support 106 far from the non-blind hole region 102 side and the first substrate 103 or the second substrate 104.
When the liquid crystal material flows from the non-blind hole region 102 to the blind hole region 101, since the thickness of the liquid crystal material in the first liquid crystal region is larger than that of the liquid crystal material in the second liquid crystal region, it is easy to cause difficulty in completely filling the space between the first substrate 103 and the second substrate 104 except for the first support 106 in the blind hole region 101.
By gradually increasing the distance between the first opening and the first substrate 103 or the second substrate 104 in the direction from the non-blind hole region 102 to the blind hole region 101, a pressure difference is generated between consecutive adjacent first supports 106 of the liquid crystal material in the direction, which is beneficial for the liquid crystal material to completely fill the space between the first substrate 103 and the second substrate 104 except the first supports 106 in the blind hole region 101.
In this embodiment, the first support 106 further includes a second opening, so that the adjacent first openings communicate with each other in a direction surrounding the blind hole area 101.
Through the arrangement that the adjacent first openings are communicated with each other through the second openings in the direction surrounding the blind hole area 101, the speed of the liquid crystal material entering the first liquid crystal area through the different first sub-openings of the first supports 106 continuously arranged along the periphery of the blind hole area 101 is favorably controlled, and the phenomenon that the speed of the liquid crystal material entering the first liquid crystal area through the different first openings is different, so that the liquid crystal material is unevenly diffused in the first liquid crystal area, bubbles are generated, and the product quality of the display panel 100 is affected is avoided.
In this embodiment, the first supporting object 106 is continuously disposed along the periphery of the blind hole region 101, so that the organic material in the non-blind hole region 102 is separated from the blind hole region 101, which is beneficial to improving the light transmittance of the blind hole region 101, further improving the light receiving amount of the optical element, improving the performances of the camera, such as resolution, and the like, and improving the product quality of the display panel 100.
EXAMPLE III
Referring to fig. 4 to 6, the present embodiment is the same as or similar to the above embodiments, except that:
the first support 106 includes a plurality of first support pillars 109 and at least one first support base 108 located between the first support pillars 109 and the first substrate 103 and/or the second substrate 104.
In this embodiment, the first supporting base 108 may be disposed in the blind hole region 101 in a whole layer.
In this embodiment, one of the first support bases 108 may correspond to one of the first support columns 109.
Through the one-to-one correspondence arrangement of the first support bases 108 and the first support columns 109, the first support bases 108 can be used for blocking the flowing of the alignment liquid for forming the alignment layer into the blind hole region 101, so that the light reaching the optical element through the blind hole region 101 due to the formation of the alignment layer in the blind hole region 101 is prevented from being influenced, the light quantity received by the optical element is further influenced, and the product quality of the display panel 100 is influenced.
Referring to fig. 6, in the embodiment, the first substrate 103 or the second substrate 104 includes a substrate 110, a thin film transistor layer 111 on the substrate 110, and an organic material layer 113 and a color resistance layer 112 on the thin film transistor layer 111.
The organic material layer 113 is located in the blind hole region 101, the color resist layer 112 is located in the non-blind hole region 102, and the organic material layer 113 may be integrally disposed with the first support base 108.
In this embodiment, the thickness of the first support 106 is the sum of the first support pillar 109 and the first support base 108, and therefore, the thickness of the first support pillar 109 and the thickness of the second support 107, and the thickness of the first support base 108 and the thickness of the color resistance layer 112 when the first support base 108 and the organic material layer 113 are integrally disposed are not particularly limited herein.
In this embodiment, the second surface of the organic material layer close to the first support pillar 109 and the third surface of the color-resisting layer close to the second support 107 may be located in the same plane. When the second surface and the third surface are located in the same plane, the thicknesses of the first support pillar 109 and the second support 107 may be the same, and both may be formed simultaneously with the same process, the same material, and the same material, which is helpful to simplify the process and improve the manufacturing efficiency of the display panel 100.
