[0002] Near Field Communication (NFC) technology is an emerging short-range wireless communication technology. In recent years, more and more display devices have gradually incorporated NFC functionality to meet various usage needs such as contactless payment, identity verification, or short-range data transmission.

[0003] In existing technologies, the way to integrate an NFC induction coil into a display device is usually by attaching the NFC induction coil to the casing of the display device or by designing additional space inside the casing of the display device to accommodate the NFC induction coil. However, since the NFC induction coil occupies a certain amount of space, it increases the overall size of the display device, which makes it impossible to meet the design requirements of a thin display device.

In this embodiment, the two ends of the wire 12 can be electrically connected to a signal processor (not shown) of the display device of the present invention, so that the signal processor can read the signal of the NFC induction coil formed by the wire 12. Figure 2As shown, in this embodiment, each of the one or more horizontal segments 112A has a width W, which is between 0.1 mm and 1 mm, and adjacent horizontal segments 112A have a spacing between 0.1 mm and 1 mm.

[0024] In this embodiment, the backlight module 11 can be a side-lit backlight module or a direct-lit backlight module. Here, a side-lit backlight module is used as an example. Please refer to [link to relevant documentation]. Figure 3 As shown, the backlight module 11 further includes a housing 113, a reflective sheet 114, a light guide plate 115, a light-emitting unit 116, a diffuser 117, and a brightness enhancement film 118. The housing 113 has a top, a bottom, and an interior. The interior of the housing 113 communicates with the top and the bottom, and the top of the housing 113 forms an opening, such as... Figure 2 and Figure 3 As shown, in this embodiment, the outer wall of the housing 113 is the side ring wall 111 of the backlight module 11, and the groove portion 112 is provided around it; the reflective sheet 114 is disposed inside the housing 113; the light guide plate 115 is disposed inside the housing 113 and on the reflective sheet 114; the light-emitting unit 116 is disposed inside the housing 113 and on the reflective sheet 114, and the light-emitting unit 116 is adjacent to one side of the light guide plate 115; the diffuser 117 is disposed inside the housing 113 and on the light guide plate 115 and the light-emitting unit 116; the brightness enhancement film 118 is disposed inside the housing 113 and on the diffuser 117; wherein, the display module 13 is disposed inside the housing 113 and on the brightness enhancement film 118, and the display module 13 displays images through the opening at the top of the housing 113. Furthermore, in this embodiment, the housing 113 is made of plastic.
