Abstract

An electronic device 1 includes a casing 3 that has layered therein: a display panel 4b; an antenna 6a, disposed in back of an effective display area of the display panel 4b, configured to be oriented so as to exhibit a directivity from the back of the effective display area of the display panel 4b toward a front surface that acts as a display surface, and to perform near field communication with an external terminal close to the display surface; a digitizer film 7a, disposed in the back of the effective display area, configured to have a plurality of scanning elements on a front surface, and to detect a position of an object on the front surface of the display panel 4b; and a shielding plate 7b disposed in back of the digitizer film 7a and the antenna 6a, and having ground connection to the digitizer film 7a.

Claims

1. An electronic device comprising

a casing configured to accommodate:

a display panel;

an antenna, disposed in back of an effective display area of the display panel, configured to be oriented so as to exhibit a directivity from the back of the effective display area of the display panel toward a front surface that acts as a display surface of the display panel, the antenna configured to perform near field communication with an external terminal close to the display panel;

a scanner, disposed in the back of the effective display area of the display panel, configured to have a plurality of scanning elements on a front surface, and to detect a position of an object on the front surface of the display panel; and

a shielding plate disposed in back of the scanner and the antenna, and having ground connection to the scanner,

the display panel, the antenna, the scanner, and the shielding plate being layered in the casing.

2. The electronic device according to claim 1, wherein the scanner is layered over the display panel such that the scanner is closer to the display panel than the antenna is.

3. The electronic device according to claim 1, further comprising a signal processing section, disposed in back of the shielding plate, configured to process a signal communicated by the antenna by near field communication.

4. The electronic device according to claim 1, further comprising a CPU configured to perform control based on a position of an object detected by the scanner, wherein

the CPU cancels a portion of the control based on the position of the object detected by the scanner, when the antenna performs near field communication with the external terminal.

5. The electronic device according to claim 1, further comprising a CPU configured to perform processing for an image to be displayed on the display panel, based on a position of an object detected by the scanner, wherein

the CPU performs control so as not to perform the processing for the image to be displayed on the display panel based on the position of the object detected by the scanner, when the antenna performs near field communication with the external terminal.
