Specifically, referring to fig. 1, an embodiment of a display panel 10 is provided, which has a display area 101 and a non-display area 102 surrounding the display area, wherein the display panel 10 includes a counter substrate 100, an array substrate 200, a liquid crystal layer 300 and a frame sealing adhesive 400; the array substrate 200 is disposed opposite to the opposite substrate 100; the liquid crystal layer 300 is disposed between the opposite substrate 100 and the array substrate 200 and corresponds to the display area 101; the frame sealing glue 400 is disposed between the opposite substrate 100 and the array substrate 200 and is disposed corresponding to the non-display area 102, one end surface of the frame sealing glue 400 is in contact connection with the opposite substrate 100, and the other end surface is in contact connection with the array substrate 200. The material of the frame sealing glue 400 includes a photo-curable glue, preferably, the photo-curable glue can be cured by using light with a wavelength ranging from 380nm to 450 nm.
The opposite substrate 100 in the embodiment of the present application has a display area 101 and a non-display area 102 surrounding the display area, and the opposite substrate 100 includes: a first substrate 110, a light shielding layer 120, a driving electrode 130, and a common electrode 140, wherein the light shielding layer 120 is disposed on the first substrate 110 and extends from the display area 101 to the non-display area 102; the driving electrode 130 is disposed between the first substrate 110 and the light shielding layer 120 and is located in the non-display area 102; the common electrode 140 is disposed on a side of the light shielding layer 120 away from the first substrate 110, and covers the first substrate 110 and the light shielding layer 120; wherein the material of the light shielding layer 120 at least within the non-display region 102 comprises an electrochromic material. The electrochromic material is capable of switching between a light transmissive state and a light opaque state. In this embodiment, it may be that only in the non-display area 102 is the light shielding layer 120 is the electrochromic material; the light shielding layer 120 may be the electrochromic material in the display area 101 and the non-display area 102.
In this embodiment, when the light shielding layer 120 is in a light-transmitting state, the liquid crystal molecules in the liquid crystal layer 300 near the non-display area 102 can fully absorb light, so as to prevent the problem of pollution between the liquid crystal molecules and the frame sealing glue 400 due to decomposition of the liquid crystal molecules; on the other hand, the frame sealing glue 400 can be photo-cured from one side of the opposite substrate 100, and the light shielding layer 100 of the opposite substrate 100 can be converted into a light-transmitting state, so that the curing opening ratio of the frame sealing glue is effectively improved, and the curing efficiency of the frame sealing glue is improved.
The electrochromic material refers to stable and reversible color change of the optical property of the material under the action of an external electric field, and the material is expressed as reversible change of color and transparency in appearance. The working principle is that the electrochromic material generates electrochemical oxidation-reduction reaction under the action of an external electric field to gain and lose electrons, so that the color of the electrochromic material changes. When the electrochromic material is not electrified, the electrochromic material is in a light-transmitting state; when the electrochromic material is electrified, the electrochromic material is in a light-tight state. Therefore, in the present embodiment, when the voltage difference between the driving electrode 130 and the common electrode 140 is less than or equal to a predetermined value, the electrochromic material is in a light-transmitting state, so as to cure the frame sealing glue 400. Preferably, the predetermined value of the voltage difference between the driving electrode 130 and the common electrode 140 is 0V, that is, the electrochromic material is in a light-transmitting state when the driving electrode 130 is powered off; when the voltage difference between the driving electrode 130 and the common electrode 140 is greater than a predetermined value, the electrochromic material is in an opaque state to provide a shading effect. Preferably, the predetermined value of the voltage difference between the driving electrode 130 and the common electrode 140 is 0V, that is, the electrochromic material is in an opaque state when the driving electrode 130 is energized. It should be understood that the transparent state and the opaque state mentioned in the present application can be understood as a transparent state and an opaque state, that is, when the driving electrode 130 is powered off, the electrochromic material is in a transparent state, and the transparent state is not limited as long as the curing of the frame sealing glue 400 can be satisfied; when the driving electrode 130 is energized, the electrochromic material is in an opaque state, preferably a black opaque state, to provide a shading effect to the maximum extent.
In an embodiment of the present application, the color of the electrochromic material is controlled by the voltage difference between the driving electrode 130 and the common electrode 140, the voltage difference between the driving electrode 130 and the common electrode 140 is different, and the color of the electrochromic material shows different states. Preferably, the color of the electrochromic material is deepened as the voltage difference between the driving electrode 130 and the common electrode 140 increases. In other words, the transparency of the electrochromic material decreases as the voltage difference between the driving electrode 130 and the common electrode 140 increases.
In the present embodiment, the voltage difference between the driving electrode 130 and the common electrode 140 ranges from 1V to 10V, preferably, the voltage difference between the driving electrode 130 and the common electrode 140 ranges from 2V to 5V, for example: 2V, 3V, 4V, 5V, 6V, 7V, 8V, 9V. It will be appreciated that when the driving electrode 130 is energized, a voltage difference exists between the driving electrode 130 and the common electrode 140, and the electrochromic material may also exhibit a color with a certain depth, that is, the transparency of the electrochromic material is less than 100%, and as the voltage difference between the driving electrode 130 and the common electrode 140 increases, the color of the electrochromic material is deepest when the voltage difference is equal to 10V, at this time, the transparency of the electrochromic material is lowest, and it is theoretically possible to achieve complete opacity, so as to achieve the best shading effect.
In the present application, the electrochromic material forming material may include an inorganic electrochromic material and/or an organic electrochromic material; a typical representation of an electrochromic material is tungsten trioxide; currently, electrochromic devices using tungsten trioxide as a functional material have been industrialized; the organic electrochromic material mainly comprises polythiophene and derivatives thereof, viologen, tetrathiafulvalene, metal phthalocyanine compounds and the like; currently, electrochromic materials using viologen as a functional material have been practically used. Preferably, the electrochromic material comprises an aromatic polyoxadiazole polymer comprising the following structural formula:
wherein n is an integer. The aromatic polyoxadiazole polymer has good heat resistance, electrical insulation, chemical corrosion resistance and high temperature resistance, so that the stability of the display panel can be effectively improved.
The array substrate 200 in the embodiment of the present application includes: a second substrate base plate 210; a color resist layer 220, wherein the color resist layer 220 is disposed on the second substrate 210 and near one side of the opposite substrate 100, and is correspondingly disposed in the display area 101; and a pixel electrode 230 disposed on the color resist layer 220 and adjacent to one side of the opposite substrate 100, and extending from the display region 101 to the non-display region 102. The pixel electrode 230 and the common electrode 140 cooperate to achieve alignment of liquid crystal molecules within the liquid crystal layer 300.

In this embodiment, a plurality of metal leads 240 are disposed in the non-display area 102 of the array substrate 210, and the frame sealing glue 400 is adhered to the metal leads 240. The roughness of the seal frame 400 near one end surface of the array substrate 200 can be increased, and the contact area between the seal frame 400 and the array substrate 200 is increased due to the metal lead 240 having a certain thickness, so that the bonding strength of the seal frame 400 and the array substrate 200 is increased. The metal wire may be formed by extending the pixel electrode 230, or may be separately prepared, and is not particularly limited. In order to achieve the bonding stability between the array substrate 200 and the frame sealing glue 400, as shown in fig. 2, it is preferable that a spacing distance L between two adjacent metal wires 240 is between 15um and 30um, for example: 20um, 25um.
In summary, the present embodiment provides an opposite substrate 100 and a display panel 10, where the display panel 10 includes the opposite substrate 100, an array substrate 200, a liquid crystal layer 300, and a frame sealing adhesive 400; the opposite substrate 100 has a display area 101 and a non-display area 102 surrounding the display area 101, and includes: the first substrate 110, the light shielding layer 120, the driving electrode 130 and the common electrode 140, wherein at least the material of the light shielding layer 120 in the non-display area 102 is an electrochromic material, and the electrochromic material is capable of switching between a light-transmitting state and a light-non-transmitting state. On the one hand, when the light shielding layer 120 is in a light-transmitting state, the liquid crystal molecules in the liquid crystal layer 300 close to the non-display area 102 can fully absorb light, so as to prevent the problem of pollution between the liquid crystal molecules and the frame sealing glue 400 due to decomposition of the liquid crystal molecules; on the other hand, the frame sealing glue 400 can be photo-cured from one side of the opposite substrate 100, and the light shielding layer 120 of the opposite substrate 100 can be converted into a light-transmitting state, so that the problem of low curing opening ratio of the frame sealing glue 400 caused by shielding of the metal lead 240 or the light shielding layer 120 is solved, the curing opening ratio of the frame sealing glue 400 is effectively improved, and the curing efficiency of the frame sealing glue 400 is improved.
When the light shielding layer 120 is in a light-transmitting state, light can be smoothly irradiated from one side of the opposite substrate 100 to the frame sealing glue 400 for curing, so that it can be ensured that the array substrate 200 has enough space for arranging wiring and circuit elements during design. The light shielding layer 120 of the display panel 10 covers the corresponding position of the frame sealing glue 400, and the backlight cannot be emitted therefrom, so as not to affect the display effect of the manufactured display panel 10.
