CUSTOMIZED CONTENTS PROVIDING SYSTEM AND METHOD FOR ELECTRONIC WALLPAPER}

The present invention relates to an application technology of electronic paper, and more particularly, to a system and method for providing customized content for an electronic wallpaper that can provide a desired content by using an electronic wallpaper implemented by an electronic paper technology.

In general, electronic paper is a kind of reflective flexible display, which has high readability, wide viewing angle, and high contrast ratio between bright white background and black particles like conventional paper and ink. This maintained bistable characteristic minimizes power loss. Such electronic paper is a new display element that replaces paper printed matter and existing display media, and various applications such as electronic newspapers, e-books, and advertisement billboards are expected.

E-Ink's microcapsules and Sipix's microcups provide electrophoresis, Gyricon's twist ball, and Bridgestone's QR-LPD (Quick Response Liquid Powder Display). The electrophoretic method using the microcapsules is known to be the best.

Meanwhile, the wallpaper is designed and distributed by a professional designer in various colors and patterns in consideration of the customer's preference, and the user selects and uses a design that suits their taste. Therefore, the conventional wallpaper has a limitation in color or pattern, so if there is no design desired by the user, the choice of the next lane was to be used.

In the case of implementing wallpaper (hereinafter referred to as 'electronic wallpaper') with electronic paper, there is a characteristic that a user can make a design and a pattern in a desired form and change the design freely due to the characteristics of the electronic paper. Therefore, if a customer wants to design an electronic wallpaper and distribute it after using the Internet, the customized design desired by the customer will be available.

The present invention has been proposed to satisfy the above needs, and an object of the present invention is to provide a system and method for providing customized content for an electronic wallpaper, which can provide a desired content by using an electronic wallpaper implemented by electronic paper technology. It is.

In order to achieve the above object, a system of the present invention includes a content database in which contents for electronic wallpaper are stored; An electronic wallpaper writing apparatus for writing and discharging content on the electronic wallpaper using content data transmitted from a service server; A service server for transmitting the content selected by the customer through the wired / wireless communication network or the content selected by the customer to the electronic wallpaper writing apparatus so as to print the desired content on the electronic wallpaper; And it characterized in that it comprises a customer terminal that can access the service server through a wired / wireless communication network.

In order to achieve the above object, another system of the present invention includes a content database in which contents for electronic wallpaper are stored; A service server converting a content selected by a customer from among contents transmitted from the customer or contents of the content database through a wired / wireless communication network into a data form that can be written on an electronic wallpaper and transmitting the data to a customer terminal; A customer terminal accessing the service server through a wired / wireless communication network, uploading its own content, receiving content data for the electronic wallpaper light downloaded from the service server, and storing the content data in a portable writing device; And a portable writing device connected to the electronic wallpaper through the electronic wallpaper interface to write the stored content received from the customer terminal on the electronic wallpaper.

The customized content providing system for the electronic wallpaper may further include a customer database in which information about the customer is stored, and the electronic wallpaper is an electrophoretic method using a microcapsule or a microcup, or a method using a twist ball. , QR-LPD (Quick Response Liquid Powder Display) using the method, the electrowetting (Electrowetting) method is made of any one.

The electronic wallpaper writing apparatus receives the electronic wallpaper source roll, cuts the predetermined size into a predetermined size, writes the content on the electronic wallpaper with data transmitted from the service server, wraps the contents in a roll form, and transmits the contents from the service server. In the process of manufacturing electronic wallpaper with electronic paper, it can be replaced with the electronic wallpaper manufacturing apparatus that manufactures and delivers the design desired by the customer.

In addition, the portable writing device includes a keypad for inputting an operation, a power supply unit for receiving a DC power to charge a battery or supplying charged power, a communication unit connected to the customer terminal, a memory, and a display unit for displaying an operation state. And a pixel electrode driver for driving the pixel electrode of the electronic wallpaper connected through the electronic wallpaper interface unit under the control of the microcomputer, and writing the stored content, and when connected to the customer terminal, the data mode is operated in the storage mode to transmit data from the customer terminal through the communication unit. When received, the received data is stored in a memory, and when a light button is input through the keypad, the electronic wallpaper interface unit checks whether the electronic wallpaper is connected, and if connected, writes the content data stored in the memory on the electronic wallpaper. Do not update contents of electronic wallpaper It consists of a compartment.

In order to achieve the above object, the method of the present invention comprises the steps of providing a main screen for the service server to select the electronic wallpaper and the design, when the customer is connected; Receiving, by the service server, an electronic wallpaper and a design through the main screen; If the customer selects his or her content, the service server uploading the corresponding content file from the customer terminal; If the customer selects the stored content, the service server providing a search screen for searching the content database; When the search is completed and the content is selected, the service server outputs cyan by executing a simulation with the selected content and the selected electronic wallpaper; And the service server checks the cyan and processes the payment, and writes the content on the electronic wallpaper to manufacture the electronic wallpaper.

The system and method for providing customized content for an electronic wallpaper according to the present invention can provide a service suited to a customer's taste by making it possible to manufacture an electronic wallpaper by directly selecting a desired content from customers distributed all over the world through the Internet. And, service providers have the effect of generating high profits through new sales models using electronic wallpaper.
