Description

電子貨架標籤Electronic Shelf Labels

本發明係有關於電子貨架標籤，尤其是一種在電子貨架標籤的電子紙顯示器中設置透明天線層者。The present invention relates to an electronic shelf label, especially a transparent antenna layer provided in an electronic paper display of the electronic shelf label.

近年來，傳統的便利商店和超市等零售業者面臨許多棘手的問題，人工成本大幅上升，市場競爭日益激烈，使得每個零售業者更加地注重店面形象，傳統的零售業者通常在貨架於貨品的前方位置放置標籤架，並在標籤架中放置紙質標籤，用以表示貨品的品名及價格等標籤資訊，當貨架上的貨品更換價格需要更改時，就需要人工進行編輯與更換紙質標籤，每次進行標籤資訊變動時，不僅耗時耗力，紙質標籤還常常會有一定的出錯率。這個問題不僅提高的人工成本和紙張成本，也導致商家對紙質標籤的更新頻率不高。隨著科技的發展，以及綠色環保理念的推動，人們希望有符合環境保護的方式更新標籤資訊的方式。In recent years, retailers such as traditional convenience stores and supermarkets have faced many thorny problems. Labor costs have risen sharply and market competition has become increasingly fierce, making each retailer pay more attention to store image. Traditional retailers are usually in front of the shelves. Place a label rack at the position and place a paper label in the label rack to indicate the label information such as the product name and price of the product. When the price of the product on the shelf needs to be changed, manual editing and replacement of the paper label are required. When label information changes, it is not only time-consuming and labor-intensive, but also paper labels often have a certain error rate. This problem not only increases labor costs and paper costs, but also causes merchants to update paper labels infrequently. With the development of technology and the promotion of the concept of green environmental protection, people hope to update the label information in a way that is in line with environmental protection.

基於上述的問題，電子貨架標籤(Electronic Shelf Labels，簡稱：ESL)應運而生，電子貨架標籤是一種替代傳統紙質價格標籤的電子顯示裝置，通過有線網路或無線網路與電子貨架標籤系統相連，並將商品的品名、價格、產地…等標籤資訊通過電子貨架標籤上的顯示器顯示出來。電子貨架標籤系統透過前述的有線網路或無線網路，將貨架上的電子貨架標籤的商品的品名、價格或產地等標籤資訊進行更換，解決了傳統紙質標籤的問題，大幅降低人工換標成本，更能進行更高頻率的動態更換標籤資訊，提供完整標籤資訊，甚至能夠與庫存系統做結合，顛覆舊有零售業運作模式，藉以提供電子化標籤資訊，提高便利性與改善營運流程，維持事業優勢。Based on the above problems, Electronic Shelf Labels (ESL for short) came into being. Electronic Shelf Labels are an electronic display device that replaces traditional paper price labels and are connected to the electronic shelf label system through wired or wireless networks. , and display the product name, price, place of origin and other label information through the display on the electronic shelf label. The electronic shelf label system replaces the label information such as the product name, price or origin of the electronic shelf label on the shelf through the aforementioned wired network or wireless network, which solves the problem of traditional paper labels and greatly reduces the cost of manual label replacement. , can perform more frequent dynamic replacement of label information, provide complete label information, and even combine with the inventory system to subvert the old retail operation mode, so as to provide electronic label information, improve convenience and improve operational processes, maintain business advantage.

有關於傳統電子貨架標籤的架構，請參閱圖1~2所示，電子貨架標籤包括電子紙顯示器1及控制電路板2，電子紙顯示器1的一側設有軟性電路板10，控制電路板2的一面設有無線網路模組20、天線模組22及軟板連接器24，其中軟板連接器24係連接軟性電路板10，而無線網路模組20連接天線模組22與軟板連接器24。使得在辦公室內的電子貨架系統(圖中未示)發出的無線標籤訊息，由天線模組22接收後，先經過無線網路模組20處理成後，再由軟性電路板10傳送到電子紙顯示器1，使得電子紙顯示器1可以輸出成所要呈現的標籤資訊。For the structure of the traditional electronic shelf label, please refer to Figures 1 and 2. The electronic shelf label includes an electronic paper display 1 and a control circuit board 2. One side of the electronic paper display 1 is provided with a flexible circuit board 10, and the control circuit board 2 One side is provided with a wireless network module 20, an antenna module 22 and a soft board connector 24, wherein the soft board connector 24 is connected to the flexible circuit board 10, and the wireless network module 20 is connected to the antenna module 22 and the soft board connector 24. The wireless tag information sent by the electronic shelf system (not shown in the figure) in the office is received by the antenna module 22, processed by the wireless network module 20, and then transmitted to the electronic paper by the flexible circuit board 10. Display 1, so that the electronic paper display 1 can output the label information to be presented.

再者，請參閱圖3所示，電子紙顯示器1與控制電路板通常是層疊狀地組裝在一起，電子紙顯示器1係為層疊狀結構，由上至下依序包括保護層11、光學連接層12、上電極層13(例如：銦錫氧化物，ITO)，電子墨水層14、下電極層15(例如：薄膜電晶體陣列，TFT array)、基板16所組成，而軟性電路板10與下電極層15連接，透過控制下電極層15所設的各電極的正、負極狀態，讓電子墨水層14呈現對應的標籤資訊。Furthermore, please refer to FIG. 3 , the electronic paper display 1 and the control circuit board are usually assembled together in a laminated manner, and the electronic paper display 1 is a laminated structure, including a protective layer 11 , an optical connection from top to bottom in sequence. The layer 12, the upper electrode layer 13 (eg: indium tin oxide, ITO), the electronic ink layer 14, the lower electrode layer 15 (eg: thin film transistor array, TFT array), the substrate 16 is composed, and the flexible circuit board 10 and the The lower electrode layer 15 is connected, and the electronic ink layer 14 displays corresponding label information by controlling the positive and negative states of the electrodes provided in the lower electrode layer 15 .

然而，電子紙顯示器1及控制電路板2通常是包覆在殼體(圖中未示)內，使得天線模組22的收訊被殼體所阻擋，再從圖3觀察可知，天線模組22設置在控制電路板2上，而控制電路板2上方有電子紙顯示器1，電子紙顯示器1也阻擋天線模組22的收訊，另外，天線模組22必須佔用控制電路板2的一部分空間，若天線模組22能夠減少甚至不佔用控制電路板2，將能夠縮小電子貨架標籤的整體體積，或者是可以增加額外的功能模組，故實有必要針對此一問題進行改善。However, the electronic paper display 1 and the control circuit board 2 are usually covered in a casing (not shown in the figure), so that the reception of the antenna module 22 is blocked by the casing. From FIG. 3 , it can be seen that the antenna module 22 is arranged on the control circuit board 2, and there is an electronic paper display 1 above the control circuit board 2. The electronic paper display 1 also blocks the reception of the antenna module 22. In addition, the antenna module 22 must occupy a part of the space of the control circuit board 2. If the antenna module 22 can reduce or even not occupy the control circuit board 2, the overall volume of the electronic shelf label can be reduced, or additional functional modules can be added, so it is necessary to improve this problem.

有鑑於先前技術的問題，本發明之一目的係將天線模組由控制電路板上移除，並改設置在電子紙顯示器，使得天線模組可以盡量地接近外界，藉以改善訊號接收的能力，並可以節省控制電路板上的布局空間，或者可以利用此空間設置其他功能模組。In view of the problems of the prior art, one of the objectives of the present invention is to remove the antenna module from the control circuit board and install it on the electronic paper display, so that the antenna module can be as close to the outside world as possible, thereby improving the ability to receive signals, And can save the layout space on the control circuit board, or can use this space to set other function modules.
