Problems solved by technology

However, since the frame sealant 3 is easily affected by the external environment, such as under high temperature and humidity conditions, it is easily corroded by water vapor 10 and leaks, which in turn causes liquid crystal leakage / pollution, and peripheral circuits, such as the signal line 9, are corroded and other adverse conditions will directly affect the yield rate of display device products
[0004] With the demand for narrow bezels of display screens in display devices, the frame sealant around the display area is becoming narrower and narrower. At the same time, the frame sealant is getting closer to the edge of the display panel, which makes the frame sealant vulnerable to external moisture, etc. Corrosion is bad, and it is easier to expose the circuit traces in the protected area to the outside world under the condition of slight coating deviation, resulting in a large number of bad circuit corrosion
[0005] In order to solve the above problems, the existing sealant can be used as the main sealant, and a circle of auxiliary sealant can be added around the main sealant to protect the main sealant. Under the condition of gluing process, this method is difficult to realize, and it is also not conducive to the narrow frame of the display screen; in addition, if image 3 , 4 As shown, the Chinese patent with the authorized announcement number CN202330959U proposes a solution to install an isolation frame 4 outside the frame sealant 3 to isolate the water vapor 10. In this solution, the isolation frame 4 is arranged between the color filter substrate 1 and the array substrate. 2, one end of the isolation frame 4 is set on one of the substrates, and the other end is suspended (that is, the isolation frame and the two substrates are not completely airtightly connected)
In this way, when the thickness of the display panel box deviates during the manufacturing process, there will be a gap between the suspended end of the isolation frame 4 and the opposite substrate, and the water vapor 10 will easily enter the interior of the isolation frame 4 through the gap, and the sealing glue will be corroded.

Embodiment 1

[0035] In this embodiment, the display panel includes a display area and a non-display area surrounding the display area, the non-display area is provided with a sealant, the sealant surrounds the display area, and the non-display area An isolation frame is also arranged in the display area, and the isolation frame is arranged on the outside of the sealant and surrounds the sealant, so that the sealant is completely isolated from the outside world.

[0036] Wherein, the display panel includes a first display substrate and a second display substrate oppositely arranged, and the sealant is disposed on the outer edge of the first display substrate and the second display substrate corresponding to the display area. position, the isolation frame is disposed outside the sealant, and the isolation frame is airtightly connected to the first display substrate and the second display substrate respectively.

[0037] In this example, if Figure 5 , 6 or 8, the isolation frame includes a...

Embodiment 2

[0053] The difference between this embodiment and Embodiment 1 is that in this embodiment, the isolation frame is made of multi-layer materials. That is, in this embodiment, at least one auxiliary layer capable of increasing the thickness of the first isolation part or the second isolation part is provided inside the first isolation part or the second isolation part, and the The auxiliary layer is made of metal material or insulating material.

[0054] The first display substrate is a color filter substrate, and a black matrix and a color filter layer are arranged on the region corresponding to the display area on the color filter substrate, columnar spacers are arranged on the color filter layer, and the color filter substrate The area corresponding to the non-display area on the top is provided with a first isolation part, the first isolation part is made of the same material as the color filter layer, its bottom end is set on the color filter substrate, its top end is set a...

Embodiment 3

[0059] The difference between this embodiment and Embodiments 1 and 2 is that the structure of the isolation frame in this embodiment is the same as that of the black matrix on the color filter substrate, the color filter layer and columnar spacers, and the thin film transistor on the array substrate in the prior art. The structures are not exactly the same.

[0060] In this embodiment, in the concave / convex or convex / concave matching structure of the first isolation part and the second isolation part in the isolation frame, the first isolation part or the second isolation part has more than two protrusions The second isolating portion or the first isolating portion has a lower concave portion matched with the raised portion, and the raised portion is in airtight contact with the lower concave portion.

[0061] Wherein, the top surfaces of the first isolation part and the second isolation part are in the shape of gears that cooperate with each other, that is, when the top surf...

Abstract

The invention belongs to the technical field of display and particularly relates to a display panel and a display device with the display panel. The display panel comprises a display area and a non-display area which surrounds the display area, wherein a frame-sealing adhesive is arranged in the non-display area and surrounds the display area; and an isolating frame is also arranged in the non-display area and outside the frame-sealing adhesive and surrounds the frame-sealing adhesive, so that the frame-sealing adhesive is completely separated from the exterior. According to the display panel, the isolating frame which can completely isolate the frame-sealing adhesive from the exterior is arranged in the display panel, so that water steam can be effectively prevented from invading the frame-sealing adhesive of the display panel, the quality of the display panel is ensured, and the quality of the display device is improved.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel and a display device including the display panel. Background technique [0002] Liquid crystal display (LCD) is an optoelectronic product that integrates large-scale semiconductor integrated circuits and flat-panel light source technology, mostly using thin-film transistors (TFT) as the control element and liquid crystal as the medium. It has low power consumption, is easy to carry, and has a wide range of applications. , high quality and other advantages have become a new generation of mainstream display devices. [0003] The display quality and overall performance of a display panel are largely affected by the material, device structure, and process. Such as figure 1 , 2 As shown, at present, most of the display panels are formed by combining the array substrate 2 and the color filter substrate 1, injecting liquid crystal material between the arr...
