Detailed Description
For the purposes of promoting an understanding of the principles and technical aspects of the disclosure, reference will now be made in detail to the embodiments illustrated in the drawings and specific examples.
It should be noted that unless otherwise defined, technical or scientific terms used in the disclosed embodiments of the present invention should be given the ordinary meanings as understood by those having ordinary skill in the art to which the present disclosure pertains. The terms "first," "second," and the like, as used in the presently disclosed embodiments, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.
The related display panel includes a display area and a surrounding non-display area. With the development trend of the full-face screen, the narrower the border of the display screen is, the higher the display area ratio is, and the more excellent experience is brought to consumers, but many technologies need to be overcome gradually.
Referring to fig. 1, the non-display area of the related display panel may be very narrow, that is, the border of the display device, but the corner area in the non-display area is most complex in structure, and the array wires are also most dense, which often becomes a stuck point for shrinking the border of the display device. Referring to fig. 2, mainly because there are EM circuits and Scan circuits at corner regions and fan-out lines between the two circuits and pixels, the fan-out lines need to be wired obliquely at corner edges, and this wiring manner occupies the width of the corner regions, resulting in a large width of the corner regions, which is disadvantageous for realizing a narrow frame. In the related technology for reducing the corner width, one way is to challenge the limit fan-out line spacing, but the short circuit risk of the method is high, and the yield of finished products is low; the other mode is to replace the mask with an ultra-high gauge, so that the cost is high; yet another approach is to compress the size of both circuits, but this can affect product performance. Therefore, the application provides a display panel which has lower cost and stable performance while reducing the width of the corner area.
