Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Embodiments of the present application provide a display panel and a display device, which will be described in detail below.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present disclosure. The display panel 100 may include an array substrate 10 and a color filter substrate 20 that are disposed opposite to each other, and a sealant 30 disposed between the array substrate 10 and the color filter substrate 20.
The array substrate 10 may include a first region 101 and a second region 102. The array substrate 10 may include a first substrate 11 and a thin-film transistor layer 20. It is understood that the thin-film transistor layer 20 is located on a side of the first substrate 11 close to the color filter substrate 20.
It should be noted that the terms "first", "second", and the like in the description of the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features.
The thin film transistor layer 20 may include a first metal layer 121, a first insulating layer 122, an active layer 123, a second metal layer 124, a second insulating layer 125, and a first ito layer 126, which are sequentially disposed on one side of the first substrate 11 close to the color filter substrate 20. In some embodiments, thin-film-transistor layer 20 may include a first portion 127 located in first region 101 and a second portion 128 located in a second region. It is understood that the first metal layer 121 is a gate layer and the second metal layer 124 is a source drain layer.
In this embodiment, the height of the first region 101 in the direction of the array substrate 10 relative to the color filter substrate 20 is greater than the height of the second region 102. That is, the height of the first portion 127 in the direction of the array substrate 10 relative to the color filter substrate 20 is greater than the height of the second portion 128.
It should be noted that in the description of the embodiments of the present application, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present application.
In some embodiments, when a voltage difference exists between the array substrate 10 and the color filter substrate 20, when the array substrate 10 uses an alternating current, the array substrate 10 may suffer from a burn problem due to insufficient insulation of the sealant 30. Note that the burn-in position generally occurs at a position with a low height in the direction of the array substrate 10 with respect to the color filter substrate 20.
It can be understood that, in the embodiment of the present application, since the height of the first region 101 of the array substrate 10 in the direction of the color filter substrate 20 is greater than that of the second region 102, the first region 101 of the array substrate 10 is generally prone to be burned.
In order to reduce the possibility of burning the first region 101 of the array substrate 10, in the embodiment of the present disclosure, a groove 201 may be disposed on a side of the color filter substrate 20 facing the array substrate 10. Note that the groove 201 corresponds to the first region 101 of the array substrate 10. That is, the groove 201 is disposed at a position where the color filter substrate 20 is opposite to the first region 101 of the array substrate 10. It will be appreciated that the width of the groove 201 is the same as the width of the first region 101.
When the array substrate 10 and the color film substrate 20 are sealed by the sealant 30, the sealant 30 may fill the groove 201 to increase the thickness of the sealant 30 at the first region 101 of the array substrate 10, thereby increasing the insulation of the sealant 30 at the first region 101 and increasing the probability of burning the first region 101 of the array substrate 10.
In some embodiments, the sealant 30 may be formed by selecting a sealant material with better insulation property.
Note that, in the embodiment of the present application, the width of the first region 101 is greater than or equal to the width of the first portion 127. The width of the first region 101 is smaller than or equal to the width of the first metal layer 121. Wherein the width of the first portion 127 is greater than or equal to the width of the active layer 123.
The color filter substrate 20 may include a second substrate 21 and an array layer 22. The array layer 22 is located on a side of the second substrate 21 close to the array substrate 10. Note that the groove 201 is located in the array layer 22.
The array layer 22 may include a black matrix 221 and a second ito layer 222. The black matrix 221 is located on a side of the second substrate 21 close to the array substrate 10. The second ito layer 222 is located on a side of the black matrix 221 close to the array substrate 10. A through hole 2221 is formed at a side of the black matrix 221 close to the array substrate 10. The second ito layer 222 is disposed along the surface of the black matrix 221 and the inner surface of the through hole 2221, so as to form the groove 201 on the color filter substrate 20.
In view of the above, the display panel 100 provided in the embodiment of the present disclosure includes an array substrate 10, a color film substrate 20, and a sealant 30; the array substrate 10 includes a first region 101 and a second region 102; the color film substrate 20 is arranged opposite to the array substrate 10, a groove 201 is formed in one side of the color film substrate 20 facing the array substrate 10, and the groove 201 corresponds to the first region 101; the sealant 30 is disposed between the array substrate 10 and the color film substrate 20, and fills the groove 201. According to the scheme, the groove 201 corresponding to the first region 101 is formed in the side, facing the array substrate 10, of the color film substrate 20, so that the frame glue 30 fills the groove 201, the thickness of the frame glue 30 corresponding to the position of the first region 101 can be increased, the insulativity of the frame glue 30 corresponding to the position of the first region 101 is increased, and the probability of burn of the array substrate 10 due to the fact that pressure difference exists between the array substrate 10 and the color film substrate 20 is reduced.
The embodiment of the present application further provides a display device, and it should be noted that the display device may include the display panel 100 in the above embodiment.
In the foregoing embodiments, the descriptions of the respective embodiments have respective emphasis, and for parts that are not described in detail in a certain embodiment, reference may be made to related descriptions of other embodiments.
