Abstract: The present disclosure proposes a plug-in touch display with a pressure sensing function. The touch display includes a capacitive touch screen to sense a touch and a display module includes a display panel having conductive layers which one of the conductive layers is configured to be used as a first capacitive sensing electrode, a backlight module positioned oppositely to the display panel, and a middle frame, configured to support the display panel and the backlight module. A second capacitive sensing electrode is positioned at a side of the middle frame, which is toward the backlight module. A gap exists between the second capacitive sensing electrode and the backlight module. The first capacitive sensing electrode and the second capacitive sensing electrode forms a capacitive sensing structure for sensing a pressure applied on the capacitive touch panel. This structure is compact and easy to produce and thus reduces the manufacturing expenses.

Abstract: A display panel and a display device are provided. A light-controlling component configured to adjust a signal transmitter is disposed on a light-emitting surface of the signal transmitter of the display panel, thereby allowing modulated light, emitted from the signal transmitter disposed at a predetermined included angle with respect to a bottom surface of a cover plate, to be totally reflected between a top surface and the bottom surface of the cover plate. Total reflection is interrupted at a position where a user's finger touches. Light is received and recognized by a plurality of light sensors on a sensor array after entering the display panel, thereby realizing under-display fingerprint recognition in a large area.
