Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions.

Referring to fig. 2 to 6, fig. 2 is a top view of a display panel according to an embodiment of the invention.

As shown in fig. 2, the display panel 100 of the present embodiment includes: a display area 20, a non-display area, and a common line area 30.

Wherein the display area 20 is used for displaying a picture, the display area 20 includes data lines and scan lines and a plurality of pixels defined by the data lines and the scan lines.

The non-display area is located outside the display area.

The common line region 30 is located in the non-display region, and in one embodiment, the common line region 30 surrounds the display region 20. Of course, it is understood that the common line region 30 may not surround the display region 20 in other embodiments. Wherein the common line region 30 is provided with an identification pattern 40, wherein the identification pattern 40 is used to identify the display panel. Each display panel corresponds to an identification pattern, that is, each display panel has a unique identification pattern, so as to distinguish the display panel from other display panels. The identification pattern is pre-set, i.e. the identification pattern is already set before the display panel is manufactured.

In one embodiment, as shown in fig. 3, the common line region 30 includes a plurality of common lines 31 crossing each other in a grid shape. That is, adjacent two common lines 31 in the horizontal or vertical direction are spaced apart from each other. Wherein a first opening (not shown) is provided on the common line 31 corresponding to the identification pattern 40 (white area in the drawing). That is, the first opening is etched on the common line 31, for example, in an embodiment, the common line 31 corresponding to the position of the identification pattern 40 may be cut off by laser etching. It is understood that the identification pattern is marked by white areas in the figures for the convenience of distinguishing the identification pattern, but the invention is not limited thereto.

In an embodiment, wherein the identification pattern 40 comprises a plurality of sub-identification patterns 41, the sub-identification patterns 41 cover the first opening. I.e., the area of the sub recognition pattern 41 is larger than the area of the first opening. In one embodiment, the sub-identification patterns 41 are in the shape of a strip, and two adjacent sub-identification patterns 41 are arranged at intervals; the sub recognition pattern 41 corresponds to the opening. The sub identification patterns 41 cover the corresponding first openings, for example, the sub identification pattern 41 of each column covers a plurality of first openings located in the same column and adjacent to each other; wherein each sub-recognition pattern 41 is composed of a first opening in the same column and a gap between two adjacent horizontal common lines 31 in the column. It is to be understood that the shape of the sub recognition pattern is not limited thereto, such as in other embodiments, the shape of the sub recognition pattern is a two-dimensional code.

In another embodiment, as shown in fig. 4 and 5, the common line region 30 includes a plurality of common lines 31 and metal blocks 32 crossing each other in a grid shape; the common line 31 is connected to the metal block 32; in one embodiment, in order to improve the stability of the signals on the common lines, a plurality of common lines 31 surround the metal block 32, that is, the metal lines 31 in a grid shape surround the metal block 32.

Wherein a set position of the metal block 32, which corresponds to the position of the identification pattern 40, is provided with a second opening (not shown). In an embodiment, wherein the identification pattern 40 comprises a plurality of sub-identification patterns 41, the position of the second opening corresponds to the position of the sub-identification patterns 41. The metal blocks 32 corresponding to the sub identification patterns 41 may be removed to obtain the second openings, and in an embodiment, the metal blocks 32 corresponding to the positions of the sub identification patterns 41 may be removed by laser etching. It will be appreciated that the manner in which the openings are provided is not limited thereto.

As shown in fig. 6, the common line region 30 includes a plurality of signal access regions 33, the signal access regions 33 are used for accessing a common signal to the common line region 30, the signal access regions 33 are provided with fanout lines corresponding to the common lines, and one end of the fanout line in the signal access region 33 is connected to the common line 31; the other end is connected with an external driving circuit.

The position of the identification pattern 40 does not overlap with the position of the signal access area 33, i.e. the identification pattern 40 is arranged in an area outside the signal access area 33. For example, it is preferable that the identification pattern 40 is disposed in a region far from the signal access region 33, and in an embodiment, when the signal access region 33 is located at an upper side and a left side of the common line region 30, the identification pattern 40 is disposed at a lower side and a right side of the common line region 30, thereby preventing access of the common signal from being affected and improving stability of the signal. It will be appreciated that the number of signal access regions 33 is not limited thereto.

It can be understood that the present embodiment forms the identification pattern by providing the openings on the metal wire or the metal block, so that the continuous light-transmitting area forms the sub-identification pattern, that is, the identification pattern may be composed of a plurality of light-transmitting areas, so as to be identified by the image identification apparatus. Of course, the number of the light-transmitting regions is not limited thereto. The identification pattern is composed of the light-transmitting area, so that the aperture opening ratio of the area can be improved, and the influence on the photocuring effect of the frame glue at the position is avoided.

In other embodiments, the identification pattern may also be formed by forming a metal block or a light-shielding layer over the common line region, i.e., the identification pattern is an opaque region. However, this reduces the aperture ratio of the region, which affects the photo-curing effect of the sealant.

In order to solve this problem, the above is merely an example, and the specific arrangement of the recognition pattern is not limited thereto.

Because the identification pattern is manufactured in the common line area, the frame of the display panel can be reduced, and meanwhile, the identification pattern is convenient to set, and the display panel is convenient to identify.

The present invention further provides a display device, which includes any one of the display panels 100, and further includes a driving circuit for inputting a driving signal to the display panel to make the display panel display a picture. In one embodiment, the display panel may be a liquid crystal display panel. The display device can be a display, a mobile phone, a tablet computer, a television, a wearable electronic device, a navigation display device and the like.

In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, therefore, the scope of the present invention shall be determined by the appended claims.
