Problems solved by technology

[0005] In view of the unreasonable setting method of the NFC antenna of the electronic products equipped with the NFC antenna and electrophoretic display, the wiring is easy to wear or the alignment is not accurate, which leads to the problem of poor signal quality of the antenna
And it limits the range of options for the housing of electronic products. In the process of producing electrophoretic displays, it has the ability to integrate NFC antennas. It is necessary to design a new electrophoretic display integrated with NFC antennas to solve the above problems.

Embodiment 2

[0033] see figure 2 , represents the NFC antenna installation structure of Embodiment 2 of the electrophoretic display integrated with the NFC antenna of the present invention. The NFC antenna 5 is arranged on the inner side of the protective film 1 of the display screen, that is, between the protective film 1 and the electrophoretic display film 2, and the NFC antenna 5 is electrically connected to the output circuit of the driving board 3 of the display screen, specifically It is connected to the output line 3 of the driving board through the conductive silver paste or other conductive material 6 on one side of the electrophoretic display film. Other structures are the same as those in Embodiment 1, and will not be repeated here.

Embodiment 3

[0035] see image 3 , represents the NFC antenna installation structure of Embodiment 3 of the electrophoretic display integrated with the NFC antenna of the present invention. The NFC antenna 5 is arranged on the outer surface of the protective film 1 of the display screen, and a protective layer 7 is arranged outside the NFC antenna 5 , and is connected to the output line of the driving board 3 through the conductive silver paste 6 . Other structures are the same as those in Embodiments 1 and 2, and will not be repeated here.

Abstract

The invention relates to NFC (Near Field Communication) technology and particularly discloses an electrophoretic display integrated with an NFC antenna. The NFC antenna is arranged on the display screen of the electrophoretic display, and an NFC interface is piggybacked on an output line of the display screen and connected with a master control board of the display screen. The electrophoretic display integrates the functions of the display screen and the NFC antenna, and can solve the problems that the NFC antenna has poorer signal quality and failed receiving due to wear of the antenna and non-alignment by directly arranging the NFC antenna on the electrophoretic display, and additionally, provide a solution scheme for conveniently receiving the NFC signal from the display interface of the display, or necessarily receiving the NFC signal from the display interface of the display.

Description

[0001] The present invention claims the priority of the Chinese patent application with the application number "201220145136.8" and the title "a display screen" filed by the applicant Truly Semiconductor Co., Ltd. on April 06, 2012, the entire content of which is incorporated in the present invention . technical field [0002] The invention relates to the technical field of near field communication, in particular to an electrophoretic display integrated with an NFC antenna. Background technique [0003] The NFC (Near Field Communication, Near Field Communication) technology is an essential technology for electronic products in the future, and has a huge market. The antenna of existing NFC products is mainly made on one side of the battery, or attached to the inside of the casing, usually on the PCB (Printed Circuit Board, printed circuit board) or FPC (Flexible Printed Circuit, flexible circuit board) , make a coil with metal traces, and then paste the PCB or FPC containing...
