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; In the display area, the flexible circuit board is bound to the non-display area, and the driving chip is bound to the side of the flexible circuit board away from the non-display area; the driving chip is connected to the array substrate through the circuit inside the flexible circuit board. Binding the driver chip on the array substrate through the flexible circuit board does not need to additionally occupy the lower step area of ​​the array substrate in the non-display area, which is conducive to realizing a narrow frame. Compared with the flexible circuit board, the lower step area of ​​the array substrate is harder and has higher impact resistance, so the impact resistance reliability of the driver chip can be improved. At the same time, the flexible circuit board does not need to be specially expanded for binding the driver chip, which saves costs.

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 ...
