The present application is described in detail below with reference to the figures and alternative embodiments.
Referring to fig. 1, fig. 1 is a schematic view of a display panel according to a first embodiment of the present application, which discloses a display panel divided into a display area and a non-display area, including: a first substrate 110, a second substrate 120, and a liquid crystal layer 130; the second substrate 120 is disposed opposite to the first substrate 110; and the liquid crystal layer 130 is disposed between the first substrate 110 and the second substrate 120 corresponding to the display region; wherein, the first substrate 110 or the second substrate 120 is provided with a black matrix 140 corresponding to the non-display region; the first substrate 110 is located on the light emitting surface of the display panel 100, and an inclined portion 150 is disposed on an edge of the outer surface of the first substrate 110 away from the second substrate 120; the light shielding layer 160 is provided to cover the surface of the inclined portion 150. The material of the light shielding layer 160 may be black ink or black glue; light leaking from the side of the display panel 100 is shielded. The inclined part 150 is arranged at the edge of the outer surface of the first substrate 110, which is far away from the second substrate 120, so that the side edge of the first substrate 110 is inclined towards the light-emitting surface side of the first substrate 110, and the side edge of the first substrate 110 is not easily affected by external factors; the influence of external factors includes that black ink used for shading on the side of the display panel 100 falls off due to collision, scratch, abrasion and the like; through the improvement of the side structure of the first substrate 110, the phenomenon that black ink on the side of the first substrate 110 is worn away due to the influence of external factors on the side of the first substrate 110 in the process of conveying or using the side of the first substrate 110 is avoided; the black ink on the side of the first substrate 110 can be well protected. On the other hand, because the black ink on the side of the first substrate 110 is not easily worn away, the integrity of the black ink on the side of the first substrate 110 is effectively protected, so that the black ink on the side of the first substrate 110 can be better shielded; thus, the problem of light leakage at the side of the display panel 100 is greatly improved.
Meanwhile, the design of the inclined portion 150 increases the area of the side of the first substrate 110 relative to the vertical side of the first substrate 110, so that the area of the light shielding layer 160 that can be coated on the side of the first substrate 110 becomes larger than before, and is easier to coat on the side of the first substrate 110; the problem of light leakage at the side of the display panel 100 caused by incomplete or uneven ink coating due to the fact that the side of the first substrate 110 is short and the area is small and ink coating is not easy to conduct is avoided.
Further, a vertical portion 111 is disposed on a side surface of the first substrate 110, the vertical portion 111 is perpendicular to the light emitting surface of the first substrate 110 and is located between the inclined portion 150 and the inner surface of the first substrate 110, one side of the inclined portion 150 is connected to the vertical portion 111, the other side of the inclined portion 150 is connected to the light emitting surface of the first substrate 110, and an included angle α between the inclined portion 150 and the vertical portion 111 is an acute angle within an angular range of 35 ° to 55 °. The side surface of the first substrate 110 having two stages, which is composed of the inclined portion 150 and the vertical portion 111, makes the structural stability of the glass substrate higher and is not easily broken at the side surface of the first substrate 110. If the angle α between the inclined portion 150 and the vertical portion 111 is smaller than 35 °, the inclined portion 150 and the vertical portion 111 tend to be aligned with each other, and during transportation or use, the inclined portion 150 is more likely to be rubbed together with the vertical portion 111, so that the light shielding layer 160 on the inclined portion 150 and the vertical portion 111 falls off, and light leakage occurs at the edge of the display panel 100; if the angle α between the inclined portion 150 and the vertical portion 111 is greater than 55 °, the inclined portion 150 tends to be aligned with the light-emitting surface of the first substrate 110, and thus the vertical portion 111 is used as the side surface of the first substrate 110, and at this time, the height of the vertical portion 111 needs to be set higher, which does not have the effect of protecting the light-shielding layer 160 on the side of the first substrate 110. Therefore, when the angle α between the inclined portion 150 and the vertical portion 111 is designed to be in the range of 35 ° to 55 °, and preferably, the angle α is 45 °, an effective chamfering structure can be formed on the side of the first substrate 110, so that the side light shielding layer 160 of the first substrate 110 is prevented from falling off, the overall structure of the first substrate 110 can be more stable, and the side of the first substrate 110 is less likely to be cracked.
Referring to fig. 2, fig. 2 is a schematic view of a display panel according to a second embodiment of the present disclosure, in which the inclined portion 150 includes at least a first inclined portion 151 and a second inclined portion 152, one side of the first inclined portion 151 is connected to the light emitting surface of the first substrate 110, the other side is connected to one side of the second inclined portion 152, and the other side of the second inclined portion 152 is connected to the vertical portion 111; the included angle β between the first inclined portion 151 and the second inclined portion 152 is an acute angle in an angular range of 35 ° to 55 °. The outer and inner surfaces of the first substrate 110 are connected by the first and second inclined parts 151 and 152 and the vertical part 111, and the light shielding layer 160 is coated on each of the first and second inclined parts 151 and 152 and the vertical part 111. Not only can the light shielding effect on the side of the display panel 100 be achieved, but also only one of the first inclined portion 151 and the second inclined portion 152 can be rubbed even if the inclined portion 150 of the first substrate 110 is rubbed by the external factors in the actual use or transportation process; this can effectively ensure that even if the inclined portion 150 is affected by external factors to be worn by touch under more extreme conditions, the whole layer or most of the black ink for shading on the inclined portion 150 will not fall off, and the shading layer 160 on the side of the first substrate 110 can still ensure the shading effect on the side of the display panel 100. Moreover, the included angle β between the first inclined portion 151 and the second inclined portion 152 is an acute angle within an angle range of 35 ° to 55 °, so that the transition at the connection between the first inclined portion 151, the second inclined portion 152, and the vertical portion 111 is smoother, an effective chamfering structure can be formed on the side of the first substrate 110, the side light shielding layer 160 of the first substrate 110 is prevented from falling off, the overall structure of the first substrate 110 can be more stable, and the first substrate 110 is not easily broken at the side of the first substrate 110.
In addition, referring to fig. 3, fig. 3 is a schematic view of a display panel in a third embodiment of the present application, and the inclined portion 150 in the present application may be an outer arc surface. When the inclined portion 150 is an outer arc surface, one side of the outer arc surface is connected with the light emitting surface of the first substrate 110, and the other side is connected with the vertical portion 111; when the light shielding layer 160 is coated on the outer arc surface and the vertical portion 111 of the inclined portion 150, not only can the good light shielding effect on the side of the display panel 100 be achieved, but also the black ink on the inclined portion 150 of the first substrate 110 can be protected to continue to achieve a good light shielding effect and be not easy to fall off even if the inclined portion 150 of the first substrate 110 is rubbed by the external factors in the actual use or transportation process. This is because, when the inclined portion 150 is an outer arc surface, the entire surface is not on the same straight line, and even if it is rubbed, all the positions of the entire inclined portion 150 are not rubbed, but only rubbed to a certain contact point; this can effectively ensure that even if the inclined portion 150 is affected by external factors to be worn by touch under more extreme conditions, the whole layer or most of the black ink for shading on the inclined portion 150 will not fall off, and the shading layer 160 on the side of the first substrate 110 can still ensure the shading effect on the side of the display panel 100.
In addition, the height of the vertical portion 111 is greater than one third of the thickness of the first substrate 110 and less than or equal to one half of the thickness of the first substrate 110. When the height of the vertical portion 111, which is a portion located at the side of the first substrate 110 and connected to the inclined portion 150, is greater than one-third of the thickness of the first substrate 110, it is possible to better apply black ink on the basis of ensuring that the vertical portion 111 and the inclined portion 150 are more easily connected; if the height of the vertical portion 111 is too short, the connection between the side inclined portion 150 of the entire first substrate 110 and the vertical portion 111 is unstable, and the chip is easily broken; in addition, the vertical portion 111 also needs to be coated with black ink in order to block the side light repeatedly refracted or reflected from the first substrate 110, and if the height of the vertical portion 111 is too short, it is more difficult to coat the black ink at the position of the vertical portion 111, which increases the difficulty of the process, and the black ink is difficult to coat uniformly, which inevitably affects the light blocking effect; on the other hand, if the height of the vertical portion 111 exceeds one-half of the thickness of the first substrate 110, the area of the inclined portion 150 is reduced accordingly, so that the black ink on the inclined portion 150 is more difficult to be coated, and the black ink coated on the inclined portion 150 may be incomplete or uneven, resulting in light leakage. Therefore, the height of the vertical portion 111 should be greater than one third of the thickness of the first substrate 110 and less than or equal to one half of the thickness of the first substrate 110. The stability of the whole structure of the glass substrate is ensured, the glass substrate is not easy to crack, the inclined part 150 and the vertical part 111 have enough area to coat black ink, a good shading effect is achieved, and light leakage from the side surface of the display panel 100 is avoided.
Referring to fig. 4, fig. 4 is a schematic view of a display panel according to a fourth embodiment of the present application, and as another embodiment of the present application, one end of the inclined portion 150 is connected to an outer surface of the first substrate 110, and the other end is connected to an inner surface of the first substrate 110. The side surface of the first substrate 110 may consist of only the inclined portion 150, and the outer surface and the inner surface of the first substrate 110 are connected by one inclined portion 150 as the side surface of the first substrate 110; the inclined portion 150 may be an outer arc surface or a stepped surface, and this scheme is exemplified by only taking the inclined portion 150 as an outer arc surface, when the inclined portion 150 is an outer arc surface, one side of the outer arc surface is connected with the outer surface of the first substrate 110, and the other side of the outer arc surface is connected with the inner surface of the first substrate 110; connecting the inner and outer surfaces of the first substrate 110 by an outer arc surface, and coating black ink on the outer arc surface to shield the side of the display panel 100 from light; because the whole extrados surface is not on the same straight line, even if the extrados surface is rubbed, all positions of the whole inclined part 150 are not rubbed, but only rubbed to a certain contact point; this can effectively ensure that even if the inclined portion 150 is affected by external factors to be worn by touch under more extreme conditions, the whole layer or most of the black ink for shading on the inclined portion 150 will not fall off, and the shading layer 160 on the side of the first substrate 110 can still ensure the shading effect on the side of the display panel 100. Moreover, when the inclined portion 150 of the outer arc surface is used as the side surface of the first substrate 110, the side surface area is larger than that when the whole plane is used as the first substrate 110, and when black ink is coated, the black ink is more easily coated more uniformly and completely, so that the side shading effect of the display panel 100 is better.
In the above scheme, the first substrate 110 is a color filter substrate 112, the second substrate 120 is an array substrate 121, and the inclined portion 150 is disposed at an edge of the color filter substrate 112, the edge being far from an outer surface of the array substrate 121.

The inclined portion 150 is disposed at the edge of the outer surface of the array substrate 121 to achieve the anti-falling effect of the light shielding layer 160 on the side of the glass substrate, which is not described in detail herein.
The inclined portions 150 are disposed on the color filter substrate 112 and the array substrate 121, so as to protect the light-shielding layers 160 on the sides of the color filter substrate 112 and the array substrate 121, and prevent the light-shielding layers 160 on the sides of the color filter substrate 112 and the array substrate 121 from falling off due to the influence of external factors during transportation or use of the light-shielding layers 160 on the sides.
Referring to fig. 6, fig. 6 is a schematic view of a display panel according to a sixth embodiment of the present application, the inclined portion 150 further includes an anti-falling structure 190, the anti-falling structure 190 may be one of a groove or a protrusion, and the anti-falling structure 190 may be formed by performing a process roughening process on a surface of the inclined portion 150, where the process includes at least one of wire drawing, etching, or laser. Through carrying out technology roughening treatment to the surface of inclined portion 150, make originally smooth surface become rough surface on the inclined portion 150, form a plurality of recesses or a plurality of archs, cover the coating black ink again on inclined portion 150 after roughening technology processing, black ink forms better adhesion on rough inclined portion 150 surface, makes black ink be difficult to drop from inclined portion 150.

The display device 10 further includes a light source 600 disposed at one side of the backlight module 200, wherein light emitted from the light source 600 passes through the first substrate 110 and the second substrate 120 from the backlight module 200, and then is reflected or refracted for multiple times in the first substrate 110 and the second substrate 120, and lateral light is formed inside the glass of the first substrate 110 and the second substrate 120, and the lateral light is absorbed by a black matrix 140 disposed between the first substrate 110 and the second substrate 120 and is shielded by a light shielding layer 160 disposed at the side of the first substrate 110 and the second substrate 120; the problem of light leakage formed laterally after light emitted from the backlight module 200 is reflected or refracted for multiple times by the glass substrate is avoided.
The display device 10 in the present application further includes a back plate 300, a rear case 400, and an elastic member 500; the backlight module 200 is disposed below the display panel 100 and located in the back plate 300; the rear case 400 wraps the display panel 100, the backlight module 200 and the back plate 300, and plays a role in protecting components inside the display device 10; when the second substrate 120 is the array substrate 121, the elastic member 500 is disposed at a lower side of the array substrate 121 for supporting the array substrate 121; attaching the elastic member 500 to the lower side of the array substrate 121, and filling a gap formed after the inclined portion 150 is disposed on the array substrate 121; the elastic member 500 can effectively support and fix the array substrate 121, and position the array substrate 121 to a certain extent, so that the array substrate 121 is not easily deviated.

The structure can effectively absorb light rays transmitted to the side surface of the display panel 100 in the glass, and the elastic member 500 can be firstly contacted with the black ink coating on the glass of the color film substrate 112, so that the function of protecting the ink layer from falling off is achieved. The problem of light leakage at the side edge of the display panel 100 caused by falling off of the coated black ink can be effectively solved. The lower side of the array substrate 121 and the joint of the elastic member 500 can be coated with ink or black glue, so that the light is prevented from being reflected and then being transmitted from the joint between the lower side of the array substrate 121 and the elastic member 500, and a better light shading effect is achieved on the joint between the array substrate 121 and the elastic member 500.

The light shielding layer 160 may be coated on the connection surface of the elastic member 500 and the second substrate 120, or the elastic member 500 may be made of black light shielding material; since the elastic member 500 supports the second substrate 120 at the lower side of the second substrate 120, when the display device 10 is frequently used or transported, the display panel 100 may be subjected to an external force, so that friction occurs between the second substrate 120 and the elastic member 500, and a contact position between the elastic member 500 and the second substrate 120 may affect the light shielding layer 160 of the inclined portion 150 on the second substrate 120, so that the light shielding layer 160 is coated on a connection surface between the elastic member 500 and the second substrate 120, and even if relative friction occurs between the second substrate 120 and the elastic member 500, the second substrate 120 can be effectively shielded from light by the light shielding layer 160 on the elastic member 500, thereby avoiding light leakage from the second substrate 120.
The glass substrate of the display panel 100 may be coated with black glue or black ink on the color filter substrate 112 and the inclined portion 150 of the array substrate 121 during the front-end process, or coated with black glue or black ink after the polarizer is attached during the middle-end process. The inclined portion 150 in the present application may be disposed at the other three sides of the non-binding side of the array substrate 121. The cover plate is kept on the binding side of the array substrate 121, that is, only three sides of the non-binding side of the array substrate 121 are in a frameless floating screen structure, and the cover plate is arranged below the three sides of the non-binding side of the array substrate 121.
Referring to fig. 8, fig. 8 is a schematic view of a display device according to another embodiment of the present disclosure, and may also be an inverted panel in which the array substrate 121 is disposed above the color filter substrate 112, and at this time, the flip chip 510 is bonded to the lower surface of the array substrate 121 above the color filter substrate 112 and is bent to the back of the backplane 300 to be connected to the printed circuit board 520; the array substrate 121 is connected to the rear case 400 through the elastic member 500, and black ink is coated on the inclined portion 150 of the array substrate 121, so that a floating screen structure having no frame on four sides is realized, and effects of shielding light and preventing the black ink from falling off are achieved.
The display panel 100 in the present application may be the liquid crystal display panel 100 or other display panels 100, and the present application only takes the liquid crystal display panel 100 as an example; generally, the liquid crystal display panel 100 generally comprises a color film substrate 112, an array substrate 121, and a liquid crystal and a sealant frame sandwiched between the color film substrate 112 and the liquid crystal substrate, wherein after the color film substrate 112 and the array substrate 121 are set in a box-to-box manner, the liquid crystal forms a liquid crystal layer 130 between the color film substrate 112 and the array substrate 121; and the display panel is disposed between the upper polarizer and the lower polarizer. The process of the display panel 100 generally includes: the front-end array process, i.e., the film, yellow light, etching and stripping, and the middle-section box process, i.e., the bonding of the color film substrate 112 and the array substrate 121, and the rear-end module assembly process, i.e., the pressing of the driving circuit board and the printed circuit board. The front-end process mainly forms the array substrate 121 to control the movement of the liquid crystal molecules; the middle process mainly includes adding liquid crystal between the array substrate 121 and the color film substrate 112; the back module assembly process is mainly to integrate the press of the driving circuit board and the printed circuit board, so as to drive the liquid crystal molecules to rotate and display images. The first substrate 110 and the second substrate 120 in this application may be one of a color filter substrate 112 or an array substrate 121.
The application can effectively shield the light transmitted to the side face in the glass substrate and prevent the ink layer from falling off. The light leakage problem at the side edge of the display device 10 with the floating screen or the full screen which is just popular is solved.
