Abstract

The invention discloses a display panel, a preparation method thereof, and a display device. The display panel includes a display area and a binding area on one side of the display area, and the display panel also includes a base substrate, a ground signal binding terminal disposed on one side of the base substrate and disposed in the binding area, a plurality of other signals The binding terminal and a plurality of signal lines, the signal lines are in one-to-one correspondence with other signal binding terminals and are electrically connected, the display panel further includes a flexible circuit board, and the flexible circuit board includes a ground binding gold finger, and the ground binding gold finger and the ground signal The bonding terminals are connected, and the vertical projection of the ground bonding gold finger on the plane where the base substrate is located does not overlap with the signal line. The display panel, the preparation method and the display device provided by the present invention solve the problem that static electricity is released to the signal line area of ​​the display panel through the grounded gold fingers on the printed circuit board, resulting in abnormal display of the display panel.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel, a method for manufacturing the same, and a display device. Background technique [0002] In recent years, display panels have been widely used in mobile phones, tablet computers, MP3, MP4 and other mobile devices. In the preparation process of the display panel, components such as printed circuit boards or ICs are usually bound to the panel. When the binding accuracy is insufficient, the gold fingers of the printed circuit board may be dislocated, so that the printed circuit board covers the area of ​​the signal lines. . At this time, when static electricity is generated on the display panel, the grounding line on the printed circuit board acts as an electrostatic discharge circuit, which is easily broken down to the signal line area of ​​the display panel through the grounded gold finger, resulting in abnormal display of the display ...
