Abstract: A display device and an array substrate including a flexible circuit substrate, first and second pad groups, a source-driving chip, and a gate-driving chip are disclosed. The flexible circuit substrate includes a substrate, first and second film layers. Outputs of the gate-driving chip are connected with the second film layer wirings through the first film layer wirings and the third via holes, and the second film layer wirings are connected with the first pad group through the first via holes and the first film layer wirings. First outputs of the source-driving chip are connected with the second pad group through the first film layer wirings in a bending area. By arranging the gate-driving chip and the source-driving chip on the flexible circuit substrate together, the sides of array substrate are unnecessary to be provided with gate-driving circuits or bonding areas therefor, thereby reducing the bezel of display device.

Abstract: The present application provides a differential signal interface and a display device adopting the differential signal interface. A plurality of different differential signals are transmitted between a transmitting end and a receiving end of the differential signal interface by a plurality of differential pairs. A plurality of moderating modules are disposed between the transmitting end and the receiving end. Each moderating module is connected to a corresponding differential pair and is configured to adjust the impedance of the transmitting end and/or the receiving end such that the impedance of the transmitting end and/or the receiving end matches the impedance of the corresponding differential pair.
