Abstract

A display apparatus comprises a back housing (DD), a backlight module (BLU) and a display module (PNL), which are sequentially arranged in a stacked manner. The display apparatus has an NFC wiring area (CC) for an NFC coil (LL) to be arranged therein; the NFC coil (LL) is arranged on the display module (PNL); and a ferrite layer (FF), which overlaps with the NFC wiring area (CC), is arranged between the back housing (DD) and a rear housing (E 1 ) of the backlight module (BLU), and/or the rear housing (E 1 ) of the backlight module (BLU) is provided with an opening which overlaps with the NFC wiring area (CC), and/or at least part of the area in which the back housing (DD) and the rear housing (E 1 ) of the backlight module (BLU) overlap with the NFC wiring area (CC) is made of a non-metallic material.

First claim

1 . A display device, comprising: a back casing, a backlight module and a display module that are stacked in sequence; the display device has an NFC wiring area for disposing an NFC coil; and the NFC coil is disposed in the display module.

2 . The display device according to claim 1 , wherein a rear casing of the backlight module is made of metal material; the rear casing of the backlight module has an opening area overlapped with the NFC wiring area; and the rear casing of the backlight module is provided with an opening in the opening area.

3 . The display device according to claim 2 , wherein the rear casing of the backlight module is provided with one opening in the opening NPC wiring area; and an edge of the opening is coincided with an edge of the opening area.

4 . The display device according to claim 2 , wherein the rear casing of the backlight module is provided with a plurality of openings in the NFC wiring area.

5 . The display device according to claim 2 , wherein the NFC coil comprises a body wiring disposed in a display area; and
the body wiring is arranged axially symmetrically; and the opening area is arranged symmetrically with respect to a symmetry axis of the body wiring.

6 . The display device according to claim 2 , wherein the NFC wiring area comprises an NFC first wiring area disposed in a display area and an NFC second wiring area disposed in a peripheral area; and
at least part of the NFC first wiring area is covered by the opening area.

7 . The display device according to claim 2 , wherein the NFC wiring area comprises an NFC first wiring area disposed in a display area and an NFC second wiring area disposed in a peripheral area; and
a geometric center of the opening area is coincided with a geometric center of the NFC first wiring area.

8 . The display device according to claim 1 , wherein the back casing is made of metal material; and the display device is provided with a ferrite layer between the back casing and the rear casing of the backlight module.

9 . The display device according to claim 8 , wherein the ferrite layer is disposed on a surface of the rear casing of the backlight module away from the display module.

10 . The display device according to claim 8 , wherein an orthographic projection of the ferrite layer on the display module is overlapped with the NFC wiring area.

11 . The display device according to claim 8 , wherein the NFC wiring area comprises an NFC first wiring area disposed in a display area and an NFC second wiring area disposed in a peripheral area; and
at least part of the NFC first wiring area is covered by the ferrite layer.

12 . The display device according to claim 8 , wherein the NFC coil comprises a body wiring disposed in a display area; and
the body wiring is covered by the ferrite layer.

13 . The display device according to claim 8 , wherein the NFC coil comprises a body wiring disposed in a display area; and
the body wiring is arranged axially symmetrically; and the ferrite layer is arranged symmetrically with respect to a symmetry axis of the body wiring.

14 . The display device according to claim 2 , wherein the back casing is made of metal material; and the display device is provided with a ferrite layer between the back casing and the rear casing of the backlight module; and
at least part of the open area is covered by the ferrite layer.

15 . The display device according to claim 14 , wherein the opening area is covered by the ferrite layer.

16 . The display device according to claim 2 , wherein the back casing is made of non-metallic material.

17 . The display device according to claim 1 , wherein at least a part area of the back casing overlapped with the NFC wiring area is made of non-metallic material; and at least a part area of the rear casing of the backlight module overlapped with the NFC wiring area is made of non-metallic material.

18 . The display device according to claim 17 , wherein both the back casing and the rear casing of the backlight module are made of non-metallic materials.

19 . An electronic equipment, comprising a display device, wherein the display device comprises:
a back casing, a backlight module and a display module that are stacked in sequence; the display device has an NFC wiring area for disposing an NFC coil; and the NFC coil is disposed in the display module.

20 .
