Abstract

The invention discloses a display panel, a manufacturing method thereof and a display device. The display panel comprises an array substrate, a flexible circuit board and a driving chip; the array substrate is divided into a display area and a non-display area; the flexible circuit board is bound into the non-display area at one edge of the array substrate, and the driving chip is bound to the side, deviating from the non-display area, of the flexible circuit board; the driving chip is connected with the array substrate through a circuit inside the flexible circuit board. The driving chip is bound to the array substrate through the flexible circuit board, there is no need to occupy a lower step area, in the non-display area, of the array substrate, and a narrow bezel is easily achieved. Compared with the flexible circuit board, the lower step area of the array substrate has higher rigidity and high impact resistance, and therefore, the impact resistance reliability of the driving chipcan be improved. In the meanwhile, there is no need to specially conduct expansion on the flexible circuit board for binding the driving chip, and the cost is reduced accordingly.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method and a display device. Background technique [0002] With the development of display technology, full-screen special-shaped display panels have a large screen-to-body ratio and ultra-narrow bezels, which can greatly improve the visual effect of viewers, and thus have received widespread attention. [0003] In order to reduce the frame of the display screen as much as possible, the common practice in the lower step area of ​​the display is to transfer the display driver chip from the lower step area to the flexible circuit board for bonding, so that the lower step area can save space for bonding. Display the space occupied by the driver chip and reduce the overall space of the step area. However, because the flexible circuit board lacks rigidity and cannot well support the display driver chip, the display driver chip has a risk of breaking ...
