Embodiment Construction

[0043] Embodiments of the disclosure will be described below with reference to the accompanying drawings. In the drawings, the same reference numerals represent the same or similar elements or method flows.

[0044] figure 1 It is a simplified schematic diagram of the electronic device 100 according to an embodiment of the present disclosure. The electronic device 100 includes a display panel 110 and a first RF antenna 120 , wherein the first RF antenna 120 vertically projects onto the display panel 110 to form a first projection area PA, and the display panel 110 includes a first sensing area SA. The first sensing area SA is located on a surface 130 of the display panel 110, wherein the magnetic field transmitted by the first radio frequency antenna 120 passes through the display panel through the first sensing area SA, and the first sensing area SA is larger than the first projection area PA (that is, The first projection area PA is located in the first sensing area SA). ...

Abstract

A display panel comprises a pixel array, multiple vertical driving lines, multiple parallel driving lines, and a first induction area. The pixel array comprises multiple pixels. One of the multiple parallel driving lines comprises a first driving line and a second driving line. The first induction area comprises part of the pixels, wherein magnetic field of a first RF antenna passes through the display panel via the first induction area, a first projection area is corresponding to a vertical projection of the first RF antenna on the display panel, and the first induction area is larger than the first projection area. The first driving line and the second driving line are configured to drive a first row of pixels among the part of the pixels, and the first driving line and the second driving line are electrically isolated from each other within the first induction area.

Description

technical field [0001] The present disclosure relates to an electronic device, in particular to an electronic device in which driving lines of a display panel are electrically isolated from each other. Background technique [0002] Radio frequency identification (RFID) is widely used in various aspects of daily life. For example, electronic payment, access control management, and data exchange between electronic devices, etc. In some electronic devices, a radio frequency antenna supporting RFID-related functions and a display panel overlap each other. For example, the near field communication (near field communication, NFC for short) antenna in the smart phone is arranged on the back of the display panel to reduce the size of the smart phone. [0003] When the radio frequency antenna and the display panel overlap each other, the magnetic field emitted by the radio frequency antenna will induce current in the display panel. The induced current flows along the circular path...
