Abstract

The present application is applicable to the technical field of display and provides a display panel and a full screen display device. In the display panel and the full screen display device disclosedin an embodiment of the present application, a drive detection circuit electrically connected to a data line lead-out terminal of a display area is arranged on a first surface of the display area ofthe display panel. Whether the display area is good before a multiplexer and a driver IC are bound on the display area; the multiplexer and the driver IC are arranged on a flexible circuit board and reversed to a second surface opposite to a first surface of the display area, and a narrow frame of the display panel can be realized.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a display panel and a full-screen display device. Background technique [0002] With the continuous development of display technology, various display devices such as mobile phones and tablet computers emerge in an endless stream. In order to achieve a narrower frame of the display device, it is necessary to increase the area ratio of the display area of ​​the display panel of the display device and reduce the area of ​​the driving circuit of the display panel as much as possible. [0003] In the existing display devices, the driving circuit is usually directly arranged on the display panel, which occupies a certain space, which is not conducive to realizing narrow frame of the display device. Contents of the invention [0004] In view of this, the embodiment of the present application provides a display panel and a full-screen display device to solve th...
