In the prior art, the liquid crystal panel has the advantages of light weight, thin body, energy and power saving and the like, thereby being widely applied. In a conventional design, a liquid crystal panel includes an upper glass substrate and a lower glass substrate, and with the development of narrow-frame and frameless liquid crystal display devices, a COF (Chip On Film) technology is adopted in an existing liquid crystal panel. At this moment, the size of lower glass substrate is greater than the size of last glass substrate, and the disconnected poor section of going out glass substrate is laminated in lower glass substrate epirelief with flexible line way board one end to buckle flexible line way board, the one end and the PCB board of flexible line way board are connected, so set up, satisfy narrow frame, no frame's needs.
However, when the liquid crystal panel and the backlight module are assembled to form the liquid crystal module, the discontinuity appears to be abrupt, which affects the display effect. In order to solve the problem that the display effect is affected by the step section, a cover plate is usually covered on the upper glass substrate so as to shield the connection area. Because the apron is located the glass substrate and need shelter from the disconnected poor section, the apron has certain width to a constraint sense is felt for the user.
The invention provides a display panel, a display device and a preparation method thereof.
In an embodiment of the present invention, referring to fig. 1, the display panel includes a color filter substrate 100, an array substrate 200 and a first light shielding layer 310, wherein the array substrate 200 and the color filter substrate 100 are stacked, the array substrate 200 has a step section 210 protruding laterally relative to the color filter substrate 100, and the step section 210 is used for electrically connecting with a circuit board 500. Referring to fig. 1 to fig. 2, the first light-shielding layer 310 is located on a surface of the array substrate 200 away from the color film substrate 100, and is opposite to the offset section 210 to shield the offset section 210.
Specifically, the color filter substrate 100 and/or the array substrate 200 may be made of aluminosilicate and other components, the liquid crystal 800 may be filled between the color filter substrate 100 and the array substrate 200, and the color filter substrate 100 and/or the array substrate 200 may be alkali glass, low-alkali glass, or alkali-free glass. Referring to fig. 1, the length of the array substrate 200 is greater than that of the color film substrate 100. When the color filter substrate 100 and the array substrate 200 are stacked, and one end of the array substrate 200 is flush with one end of the color filter substrate 100, the array substrate 200 has a step section 210 protruding laterally relative to the color filter substrate 100.
Referring to fig. 1, the array substrate 200 has a first surface 201 and a second surface 202 opposite to the first surface 201, the first surface 201 faces the color filter substrate 100, and the step section 210 located on the first surface 201 is used for electrically connecting with the circuit board 500, so as to drive the display panel. It can be understood that the display panel may include an IC device and a flexible printed circuit 600, the IC device is packaged on the flexible printed circuit 600, and two ends of the flexible printed circuit 600 are electrically connected to the step-off section 210 and the circuit board 500, respectively. It should be noted that the color filter substrate 100 may also have a step section 210 protruding laterally relative to the array substrate 200 for electrically connecting with the circuit board 500, and one surface of the color filter substrate facing away from the array substrate is used for a user to view.
Referring to fig. 1, a second surface 202 of the color filter substrate 100 facing away from the display surface is for a user to view, that is, the color filter substrate 100 faces the backlight side, and the array substrate 200 faces the human eye side. The first light shielding layer 310 is disposed on the second surface 202 at a position corresponding to the differential section 210, so as to shield the differential section 210, and prevent the flexible circuit board 600 connected to the differential section 210 from being exposed to affect the appearance of the product. The first light-shielding layer 310 may be made of various materials, and only the step section 210 may be shielded.
The first light-shielding layer 310 has various colors, and in order to integrate with the array substrate 200 to a higher degree, referring to fig. 1, in an embodiment, the color of the first light-shielding layer 310 is black. When the color of the first light shielding layer 310 is black, the color of the array substrate 200 of the display panel is integrated with the first light shielding layer 310, so that a user cannot see the existence of the first light shielding layer 310 when the screen is not lighted, the integration is presented, and meanwhile, no cover plate is bound, and a frameless visual effect is brought to people.
The invention is equivalent to that the original cover plate exposed outside is fused into the display panel and is integrated with the glass substrate, the display panel has beautiful integral design, brings wider visual area to users to a certain extent, eliminates the binding sense of the original thick frame (namely the cover plate) and has more fashionable sense in shape. Since the cover plate of the common shielding offset section 210 has a certain height relative to the surface of the glass substrate, when a user watches and uses the display panel, the cover plate partially shields the display panel at a certain angle, which affects the watching of the user. The thickness of the first light shielding layer 310 is smaller, so that the visual area and the visual angle of a user are increased, and the user experience is further improved.
Meanwhile, the size of the array substrate 200 is larger than that of the color film substrate 100, and the second surface 202 of the array substrate 200 faces outward for displaying picture information, compared to the conventional color film substrate 100 facing toward the eye, the array substrate 200 facing toward the backlight, and the color film substrate 100 with a smaller size facing outward (the cover plate necessarily covers the color film substrate 100), the display area of the display panel is larger, the visible area of a user is further increased, the visible area of the user is further increased, and the user can conveniently watch the display panel.
According to the technical scheme of the invention, the first shading layer 310 is arranged on the surface of the array substrate 200, which is far away from the color film substrate 100, so that the offset section 210 is shaded. Because first light shield layer 310 has the effect of sheltering from the light, incident light can't see through the offset section 210 of array substrate 200 under the sheltering from of first light shield layer 310, and then can't see offset section 210 in display panel's outside, need not use the outline that covers offset section 210, has eliminated display panel's constraint and has felt, provides bigger viewing angle, and convenience of customers watches. When the display panel is not lightened, the display panel is integrated without the constraint of a frame, and a frameless visual effect is brought to people, so that the user experience is improved.
Further, in order to avoid the user seeing the step section 210 from the second surface 202, please continue to refer to fig. 1, in an embodiment, the bottom of the array substrate 200 is flush with the lower edge of the first light shielding layer 310, and the upper edge of the first light shielding layer 310 is not lower than the projection line of the step section 210 on the first light shielding layer 310.
Referring to fig. 1, the upper edge of the first light shielding layer 310 is higher than or equal to the projection line of the differential section 210 on the first light shielding layer 310, so that the user is prevented from seeing the differential section 210, the flexible circuit board 600 and the circuit board 500 connected with the differential section 210 from the upper edge of the first light shielding layer 310, the problem of light leakage at the upper end of the differential section 210 is solved, and meanwhile, the display panel is prevented from adopting a cover plate for light shielding limitation in the display device manufacturing process, thereby realizing frameless display.
In order to achieve light leakage of the step section 210, in an embodiment, the thickness of the first light shielding layer 310 is less than or equal to 20 nm. Considering that the thickness of the first light shielding layer 310 is too large, which may cause the display panel to feel thick and affect the appearance of the product, the thickness of the first light shielding layer 310 is not greater than 20 nm.
Referring to fig. 1 and 3, in an embodiment, the display panel further includes an upper polarizer 710, and the upper polarizer 710 is disposed on the first light shielding layer 310 and the array substrate 200.

Referring to fig. 1 and fig. 3, the display panel may further include a lower polarizer 720 and a backlight module 910, wherein the lower polarizer 720 is disposed on the color filter substrate 100, and the backlight module 910 is located on a surface of the lower polarizer 720 away from the color filter substrate 100. The surface light source provided by the backlight module 910 is deflected by the lower polarizer 720, then refracted by the liquid crystal 800 molecules between the color film substrate 100 and the array substrate 200, and finally deflected by the upper polarizer 710 and then transmitted out, thereby realizing image display. It is noted that the upper polarizer 710 and/or the lower polarizer 720 may use high haze polarization with a haze of 20% to 45%.
With reference to fig. 3, the display panel may further include a buffer 920, where the buffer 920 is used to fix the positions of the lower polarizer 720 and the backlight module 910, so as to mount the color film substrate 100, the array substrate 200 and the backlight module 910; on the other hand, the buffer function can be realized, and the collision damage between the parts can be avoided. It is understood that the buffer 920 may be a light blocking tape.
Referring to fig. 3, the display panel may further include a frame 930, where the frame 930 includes a middle frame 931 and a back frame 932 connected to the middle frame 931. Referring to fig. 3, in an embodiment, the middle frame 931 is installed at ends of the upper polarizer and the step section, and the end of the middle frame 931 is flush with an outer surface of the upper polarizer.

The middle frame 931 does not cover the second surface 202 of the array substrate 200, so that a user can only see a small portion of the middle frame 931 on the side of the upper polarizer 710 of the display panel away from the array substrate 200, thereby obtaining a better product visual effect. The back frame 932 is located behind the backlight module 910, so as to protect the backlight module 910, the circuit board 500 and the flexible circuit board 600 from being exposed to the outside and dust or flying insects.
In addition to the step section 210, the remaining three peripheral edges of the array substrate 200 may also be connected with metal wires, so that the metal wires are exposed on the second surface 202 of the array substrate 200, and in order to solve this problem, referring to fig. 2, in an embodiment, the display panel further includes a second light shielding layer 320, a third light shielding layer 330, and a fourth light shielding layer 340, the second light shielding layer 320 is located on the upper edge of the array substrate 200, and the third light shielding layer 330 and the fourth light shielding layer 340 are respectively located on the left and right side edges of the array substrate 200.
