Description

Display panel and display device

technical field

The utility model relates to the field of display technology, in particular to a display panel and a display device.

Background technique

With the continuous progress of liquid crystal display technology, the requirements for the ultra-narrow frame of the liquid crystal display panel are getting higher and higher. It is particularly important to reduce the width of the sealant and the width of the polyimide (PI) border area to achieve ultra-narrow bezels.

FIG. 1 shows a schematic diagram of an existing ultra-narrow bezel display panel. As shown in Figure 1, the substrate 101 and the substrate 102 are relatively placed, a protective layer 105 is formed on the opposite side of the substrate 102 and the substrate 101, an orientation layer 103 is formed on the protective layer 105, and an orientation layer 103 is formed on the opposite side of the substrate 101 and the substrate 102. There is an alignment layer 103, and a liquid crystal layer 104 is sandwiched between the substrate 101 and the substrate 102. There is an alignment layer edge region 106 at the edge of the panel. Since the alignment film will be uneven at the edge of the alignment layer during the formation process, the alignment layer is generally The thickness of the edge region 106 of the layer is 3 to 4 times the thickness of the alignment layer 103 . Since the matching between the sealant and the alignment layer is poor, the display panel is sealed with the sealant 107 outside the edge region 106 of the alignment layer. Since the edge area 106 of the alignment layer does not overlap with the sealant 107, the width of the frame is greatly increased. Moreover, since the frame sealant 107 is in direct contact with the protective layer 105, the contact area between the frame sealant 107 and the protective layer 105 is relatively small, so it is difficult to reduce the width of the glue while ensuring the adhesion strength, which cannot satisfy the needs of today's consumers for ultra-thin products. The demand for narrow bezel products.

Detailed ways

Embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings.

Fig. 2 shows a schematic diagram of an ultra-narrow bezel display panel according to an embodiment of the present invention, and Fig. 3 shows a cross-sectional view taken along line A-A' in Fig. 2 . As shown in FIGS. 2 and 3 , similar to the display panel in the prior art, the substrate 201 and the substrate 202 are placed opposite to each other, and the substrate 201 and the substrate 202 may be glass substrates. A protective layer 205 is formed on the opposite side of the substrate 202 and the substrate 201, an alignment layer 203 is formed on the protective layer 205, and an alignment layer 203 is also formed on the opposite side of the substrate 201 and the substrate 202, and the alignment layer is preferably made of polyimide. become. A liquid crystal layer 204 is interposed between the substrate 201 and the substrate 202 . There is an alignment layer edge region 206 at the edge of the panel. The difference from the prior art is that the ultra-narrow bezel panel according to the embodiment of the present invention has a protective layer 208 formed on the orientation layer area 206, and a sealant 207 is formed between the upper and lower protective layers 208 to seal the display. panel. In this way, the frame sealant overlaps with the edge area of the alignment layer, thereby reducing the frame width of the display panel.

In addition, a uniform trapezoidal concave hole 209 is formed on the protective layer 208 through processes such as exposure. When coating the sealant, the sealant fills the recesses 209 , so that the adhesion between the protective layer 208 and the sealant 207 can be increased. As shown in Figure 2, the widths of the upper and lower protective layers 208 are equal, and the width of the sealing glue 207 is equal to the width of the protective layer 208, so that the contact area between the sealing glue and the protective layer is the largest, further increasing the contact area between the protective layer and the sealing layer. Adhesion between frame glue. The width of the sealant 207 may also be slightly larger than the width of the protective layer 208 , for example, within 0.1 mm wider than the width of the protective layer 208 .

In the prior art, as shown in FIG. 1 , the alignment layer 103 is directly coated on the protection layer 105 without any adverse effects. In the embodiment of the present invention, coating the protective layer 208 on the edge region 206 of the alignment layer will not cause any adverse effects, and the protective layer and the alignment layer match well. The adhesion strength between the protective layer and the frame sealant is significantly greater than the adhesion strength between the orientation layer and the frame sealant. By adding between the orientation layer and the frame sealant, both have better adhesion strength and no Any adverse effects on the protective layer can improve the sealing strength of the display panel and reduce the glue width, thus meeting the design requirements of ultra-narrow bezels.
