The touch panel and the touch screen are described in detail below with reference to fig. 1 to 5.

Referring to fig. 1, and as necessary, referring to fig. 2 to 5, the present utility model provides a touch panel 10 having a display area S1 and a non-display area S2 located at the periphery of the display area S1. The touch panel 10 includes a substrate layer 11 and a display panel layer disposed on the substrate layer 11.

The display panel layer includes a touch layer 18, the touch layer 18 includes a touch signal line layer 182 located in the non-display area S2 and a buffer layer 180 covering the surface of the touch signal line layer 182, and the buffer layer 180 includes at least two flexible film layers spaced apart from each other.

The flexible film layer may be an organic material layer, and may be formed of an organic material.

In some embodiments, the non-display area S2 has a first non-display area S21 located at a side of the display area S1, and the touch panel 10 further includes a bending area located at a side of the first non-display area S21 away from the display area S1, and a binding area located at a side of the bending area away from the first non-display area S21; wherein the buffer layer 180 is located in the first non-display area S21.

Referring to fig. 3, in some embodiments, the touch layer 18 includes an inorganic insulating layer 181, a touch electrode layer and a touch electrode line layer 182 disposed on the inorganic insulating layer 181, and a planarization layer 183 disposed on the touch electrode layer and the touch electrode line layer 182. The buffer layer 180 is a planarization layer of the touch layer 18. It will be appreciated herein that at least a portion of the membrane layer of buffer layer 180 is the same material as touch layer 18.

In some embodiments, the buffer layer 180 includes a spacer layer between at least two flexible film layers, the spacer layer and the flexible film layers having different material strengths such that the spacer layer can counteract or block a portion of the stress, thereby reducing downward stress transfer and protecting the touch signal lines.

Referring to fig. 3, in some embodiments, the buffer layer 183 includes a first flexible film layer 1831, a first spacer layer 1832, a second flexible film layer 1833, a second spacer layer 1834, and a third flexible film layer 1835 sequentially covering the touch electrode line layer 182.

Here, the first spacer layer 1832 and the second spacer layer 1834 have different material strengths from the first flexible film layer 1831, the second flexible film layer 1833, and the third flexible film layer 1835. The material of each flexible film layer may be the same here. The material of each spacer layer may be the same. Of course, they may all be different.

Referring to fig. 5, the buffer layer includes only two flexible film layers 1831 and 1833 and an interlayer 1832.

Of course, in other embodiments, the buffer layer may also include more flexible film layers, as not limited in this regard.

In some embodiments, the spacer layer has a material strength that is less than the material strength of the flexible film layer. By adopting the arrangement, the spacer layer has better flexibility, and can absorb stress better so as to play a role in buffering better.

In some embodiments, the spacer layer (i.e., the space) between the at least two flexible film layers is a gap between adjacent two flexible film layers.

For example, as shown in fig. 4, the spacer layers (i.e., the gaps) 1832 and 1834 between the flexible film layers are gaps and do not fill the material layers, so that when the flexible film layer on the top layer breaks due to stress, the gaps can block the transmission of stress, thereby being beneficial to protecting other flexible film layers and other film layers below.

In some embodiments, the buffer layer 180 has a thickness of 3 μm to 4 μm. The buffer layer 180 has an overall thickness of 3 μm to 4 μm, and achieves a good buffer effect without changing the cause structure size so as not to affect other structures.

In addition, the display panel layer further comprises a bottom buffer layer 12, an insulating layer 13 and a driving circuit layer which are positioned on the bottom buffer layer 12, a light emitting layer and a packaging layer 17. The driving circuit layer has a planarization layer 15, and the light-emitting layer has a planarization layer 16. The encapsulation layer 17 has a first inorganic layer 171, an organic layer 172, and a second inorganic layer 173.

The utility model further provides a touch screen, which comprises the polarizer 30, the cover plate 40 and the touch panel 10.

The polarizer 30 is located on the touch layer 18, and the cover 40 is located on a side of the polarizer 30 facing away from the touch panel 10.

Referring to fig. 2, the front projection of the polarizer 30 in the thickness direction T of the touch screen is within the front projection range of the cover 40 in the thickness direction T of the touch screen, and a flexible adhesive layer 50 is disposed on the edge of the polarizer 30. The glue layer 50 may be an MCL glue layer, and may be a glue layer structure in which the glue layer filled in the bending region extends. The inventors have found that, since the upper portion of the cured material can abut against the cover 40, when the cover 40 is subjected to external impact (e.g., dropping), the top stress of the adhesive layer 50 is concentrated, and is transferred downward, which easily results in breakage of the touch electrode layer.

In some embodiments, the orthographic projection of the polarizer 30 in the thickness direction T of the touch screen at least partially overlaps the orthographic projection of the buffer layer 180 in the thickness direction of the touch screen.

In some embodiments, the distance D2 between the edge of the buffer layer 180 facing away from the display area S1 and the edge of the polarizer 30 is less than or equal to 100 μm, so as to buffer the film layer corresponding to the edge of the polarizer 30 and reduce the influence on other film layers or structures.

The distance D1 between the edge of the buffer layer 180 facing the display area S1 and the edge of the polarizer 30 is less than or equal to 100 μm, so as to buffer the film layer corresponding to the edge of the polarizer 30 and reduce the influence on other film layers or structures.
