Description

兼具近場通訊天線功能的觸控顯示裝置Touch display device with near field communication antenna function

本新型涉及一種觸控顯示裝置，特別是指兼具近場通訊天線功能的觸控顯示裝置。The new model relates to a touch display device, in particular to a touch display device with a near field communication antenna function.

近場通訊(Near Field Communication, NFC)技術可以讓兩個電子裝置(其中一個通常是行動裝置，例如智慧型手機或平板電腦)在相距幾公分的距離內建立無線傳輸路徑，並完成數位資訊的傳送/接收。NFC技術的應用相當廣泛，已是目前行動裝置必備之功能之一，舉例而言，NFC技術的常見應用包含電子身分證、鑰匙卡、消費行動支付、門禁管制、資料傳輸(例如分享圖文、影片、電話號碼)、讀取電子標籤的資訊…等。Near Field Communication (NFC) technology allows two electronic devices (one of which is usually a mobile device, such as a smartphone or tablet) to establish a wireless transmission path within a distance of several centimeters, and complete the transmission of digital information. transmit/receive. NFC technology is widely used and is one of the necessary functions of current mobile devices. For example, common applications of NFC technology include electronic ID cards, key cards, consumer mobile payment, access control, data transmission (such as sharing pictures, texts, etc.) video, phone number), information on reading electronic tags...etc.

天線是NFC技術中用以接收及輻射電磁波信號的構件，也就是說，習知NFC天線是安裝在行動裝置的機殼內部的獨立構件，其通常是成形於印刷電路板(PCB)或軟性電路板(FPC)上，故習知NFC天線為實體構造而佔有一定體積，行動裝置的機殼內需預留空間以供設置該NFC天線。The antenna is a component used in NFC technology to receive and radiate electromagnetic wave signals, that is to say, the conventional NFC antenna is an independent component installed inside the casing of the mobile device, which is usually formed on a printed circuit board (PCB) or a flexible circuit. Therefore, the conventional NFC antenna is a physical structure and occupies a certain volume, and a space needs to be reserved in the casing of the mobile device for arranging the NFC antenna.

然而，行動裝置的機殼內部空間相當有限，諸如電池、相機、主機板等零組件的配置相當緊湊，如無多餘空間能置放該NFC天線時，則須於機殼的內表面另外開設凹槽以供容納該NFC天線，如此增加機殼設計難度與組裝難度。However, the internal space of the casing of the mobile device is quite limited, and the configuration of components such as batteries, cameras, and motherboards is quite compact. If there is no extra space to place the NFC antenna, an additional recess must be provided on the inner surface of the casing. The slot is used for accommodating the NFC antenna, which increases the difficulty of design and assembly of the casing.

有鑒於此，本新型的主要目的是提供一種兼具近場通訊天線功能的觸控顯示裝置，以期克服先前技術所述習知NFC天線為獨立構件所導致後續組裝困擾的問題。In view of this, the main purpose of the present invention is to provide a touch display device with a function of a near field communication antenna, so as to overcome the problem of subsequent assembly troubles caused by the conventional NFC antenna described in the prior art as an independent component.

When the device is installed, the metal frame can be directly electrically connected to the control chip to realize the NFC sensing function. With the structure of the novel touch display device, compared with the conventional independent NFC antenna, it is not necessary to install an additional NFC antenna for the applied electronic device, so the placement space for an additional NFC antenna can be saved. , the mechanism design of the electronic device is simplified, and the configuration of other components of the electronic device is not interfered, so as to achieve the effect of improving the yield and saving the cost, and overcome the problems mentioned in the prior art.
