Abstract

The invention relates to a near field communication technology, and particularly discloses an organic electroluminescent display integrated with a near field communication (NFC) antenna, which is an On Cell or In Cell type organic electroluminescent display integrated with a termination point (TP). The NFC antenna is arranged on a display screen of the organic electroluminescent display; an NFC interface is connected with an output line of the display screen and connected to a control main board of the display screen. According to the organic electroluminescent display, the functions of the display screen and the NFC antenna are integrated; the NFC antenna is directly arranged on the organic electroluminescent display, so that the problems of poor signal quality and failure in signal receiving which are caused by abrasion of an NFC antenna interface and poor alignment effect are solved; furthermore, by the organic electroluminescent display integrated with an NFC antenna, an NFC signal can be received conveniently from the display surface of the display, and a solution is provided when an NFC signal has to be received from the display surface 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 present invention relates to the technical field of near field communication, in particular to an organic electroluminescent display integrated with an NFC antenna, especially suitable for an On Cell or In Cell organic electroluminescent display integrated with a TP. 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 (Fl...
