Abstract

The application provides a display device for reducing bounciness of a FPC (Flexible Printed Circuit). The display device comprises a display panel, a FPC board and a conduction part, wherein the display panel comprises a driving chip; the FPC board comprises a main body part and a projection part; the main body part comprises a binding region; the binding region comprises a plurality of golden fingers arranged along a first direction; the FPC board is electrically connected with the driving chip by the binding region; the projection part is arranged at at least one side edge of the main bodypart and comprises exposed copper; and the conduction part at least partially covers the driving chip and is grounded by the exposed copper.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a display device. Background technique [0002] An integrated driver chip (driver Integrated Circuit, driver IC) is disposed on a thin film transistor (Thin Film Transistor, TFT) glass substrate of the display device. During the use of the display device, a large amount of contact static electricity and air static electricity will be accumulated in the display device. If the static electricity is not released in time, the driver chip may be damaged. [0003] At present, in order to discharge the static electricity accumulated in the display device, the structure design of the existing display device is as follows: a conductive cloth is attached to the driver chip, and the conductive cloth is extended to the flexible printed circuit board (Flexible Printed Circuit, FPC) and then grounded, so that Discharge static electricity by grounding with a conductive cloth. ...
