Definitions
- the present disclosure relates to the technical field of near field communication, and particularly, to a touch panel integrated with an NFC antenna.
- NFC Near Field Communication
- An antenna of a conventional NFC product is mainly provided on a side of a cell, or is attached on an inner side of a housing.
- coils made of a wire are provided on a Printed Circuit Board (PCB) or on a Flexible Printed Circuit (FPC), and then the PCB or the FPC with the coils is attached on the cell or on the housing.
- PCB Printed Circuit Board
- FPC Flexible Printed Circuit
- Abrasion or misalignment is easy to occur at a wiring junction of the NFC antenna due to repeated disassembly and assembly of the cell and the housing, thereby resulting in deterioration of antenna signal quality and affecting the use of functions of the NFC product.
- the antenna of the NFC product is generally located on the inner side of the housing, transmission of an NFC signal may be affected if the housing is made of a metallic material. Thus, sturdy metallic materials are excluded when selecting the material for the housing of the electronic product.
- the touch screen also known as “a touch-control screen” or “a touch-control panel”, is an inductive liquid crystal display device which may receive an input signal from, for example, a contactor.
- a touch-control screen is an inductive liquid crystal display device which may receive an input signal from, for example, a contactor.
- the touch screen includes a touch detection component and a touch screen controller.
- the touch detection component is mounted in front of the display, and is for detecting a touch position of a user and transmitting the touch position to the touch screen controller after receiving the touch position.
- the touch screen controller mainly functions to receive touch information from a touch point detection device, transform the touch information into a contact coordinate, and transmit the contact coordinate to a CPU, and the touch screen controller may further receive a command transmitted by the CPU and execute the command.
- the NFC antenna is not reasonably arranged in the conventional electronic product integrated with the NFC antenna and the touch screen, abrasion or misalignment is easy to occur at the wiring junction of the NFC antenna, thereby resulting in deterioration of antenna signal quality and restricting selectable materials for the housing of the electronic product. Since the touch screen is integratable with the NFC antenna during the process of manufacturing the touch screen, it is necessary to design a new touch screen integrated with the NFC antenna to solve the above disadvantages.
- the disclosure intends to provide a touch panel integrated with an NFC antenna, which may prevent abrasion or misalignment at a wiring junction of the antenna and is advantageous to ensure the quality of an antenna signal.
- an electronic product having the touch panel described above transmits a signal from a touch surface, and thus a selection of a material for a housing is not limited by the NFC antenna.
- a touch panel integrated with an NFC antenna is provided.
- the NFC antenna is provided on the touch panel and is connected to a mainboard with a control chip.
- the touch panel includes touch panel lens and a touch panel sensor.
- the touch panel lens and the touch panel sensor having a separated “Lens+TP sensor” structure or have an integrated one glass solution (OGS) structure; and the NFC antenna is provided on the touch panel lens, the NFC antenna is led to an output circuit of the touch panel via the touch panel sensor, or the NFC antenna is directly led to the output circuit of the touch panel.
- OGS integrated one glass solution
- the NFC antenna is provided between the touch panel lens and the touch panel sensor and is located at borders.
- a Black Matrix is printed at borders of an inner surface of the touch panel lens to form a black and opaque border of the touch panel.
- the NFC antenna is provided at borders of an outer surface of the touch panel lens and is covered with an insulation protective film; or the NFC antenna is provided at borders of an outer surface of the touch panel sensor and is covered with an insulation protective film.
- the NFC antenna is led to the output circuit by being electrically connected to the touch panel sensor via a conductive material, or the NFC antenna is directly led to the output circuit.
- the NFC antenna is made from multiturn coils formed by a conductive material wiring.
- the NFC antenna is formed with a wiring by low resistivities materials including silver, copper and aluminum.
- the multiturn coils are wound to have an annular shape matching with an outline of a product.
- the multiturn coils are wound to have a rectangle shape or a circular shape.
- a side of the multiturn coils closer to an inner side of the touch panel is covered with a layer of transparent ferrite material.
- the NFC antenna is directly provided on the touch panel, and functions of touch-control and the NFC antenna are integrated. Since the touch panel is an essential portion of nowaday electronic products, particularly, is essential to mobile phone products, and the touch panel is located on the outermost of the electronic product, it is advantageous for the antenna to receive and transmit signals. Since the touch panel itself is a component without needs of disassembly and assembly, the conventional problems of abrasion or misalignment at a wiring junction are avoided during the usage of the NFC antenna.
- a solution is provided for advantageously receiving an NFC signal from a touch surface of the touch panel, or for a case that the NFC signal must be received from the touch surface of the touch panel.
- a signal is transmitted at the touch surface in an electronic product having the touch panel described above, and thus the selection of materials for a housing is not limited by the NFC antenna.
- FIG. 1 is a front view of a mounting position, on a TFT display screen, of an NFC antenna in a touch panel integrated with the NFC antenna according to a first embodiment of the present disclosure
- FIG. 2 is a side view of a mounting structure of an NFC antenna in a touch panel integrated with the NFC antenna provided in the present disclosure
- FIG. 3 is a side view of a mounting structure of an NFC antenna in a touch panel integrated with the NFC antenna according to a second embodiment of the present disclosure.

Description
- This application claims the priority to Chinese Patent Application No. 201220145136.8, entitled “DISPLAY SCREEN”, filed with the State Intellectual Property Office of People's Republic of China on Apr. 6, 2012; and Chinese Patent Application No. 201210232612.4, entitled “TOUCH SCREEN INTEGRATED WITH NFC ANTENNA”, filed with the State Intellectual Property Office of People's Republic of China on Jul. 5, 2012, which are hereby incorporated by reference in their entireties.
- The present disclosure relates to the technical field of near field communication, and particularly, to a touch panel integrated with an NFC antenna.
- Near Field Communication (NFC) technology is an essential technology for the electronic products in the future and has a huge market. An antenna of a conventional NFC product is mainly provided on a side of a cell, or is attached on an inner side of a housing. In a general way, coils made of a wire are provided on a Printed Circuit Board (PCB) or on a Flexible Printed Circuit (FPC), and then the PCB or the FPC with the coils is attached on the cell or on the housing. Main disadvantages are described as follows. Abrasion or misalignment is easy to occur at a wiring junction of the NFC antenna due to repeated disassembly and assembly of the cell and the housing, thereby resulting in deterioration of antenna signal quality and affecting the use of functions of the NFC product. In addition, since the antenna of the NFC product is generally located on the inner side of the housing, transmission of an NFC signal may be affected if the housing is made of a metallic material. Thus, sturdy metallic materials are excluded when selecting the material for the housing of the electronic product.
- For example, a number of electronic products integrated with the NFC antenna and a Touch Screen have the above disadvantages. The touch screen, also known as “a touch-control screen” or “a touch-control panel”, is an inductive liquid crystal display device which may receive an input signal from, for example, a contactor. In operation, firstly the touch screen mounted in a front end of a display is touched by a finger or other objects, and then an input for selection information is positioned by a system based on a position of an icon or a menu touched by the finger. The touch screen includes a touch detection component and a touch screen controller. The touch detection component is mounted in front of the display, and is for detecting a touch position of a user and transmitting the touch position to the touch screen controller after receiving the touch position. The touch screen controller mainly functions to receive touch information from a touch point detection device, transform the touch information into a contact coordinate, and transmit the contact coordinate to a CPU, and the touch screen controller may further receive a command transmitted by the CPU and execute the command.
- Since the NFC antenna is not reasonably arranged in the conventional electronic product integrated with the NFC antenna and the touch screen, abrasion or misalignment is easy to occur at the wiring junction of the NFC antenna, thereby resulting in deterioration of antenna signal quality and restricting selectable materials for the housing of the electronic product. Since the touch screen is integratable with the NFC antenna during the process of manufacturing the touch screen, it is necessary to design a new touch screen integrated with the NFC antenna to solve the above disadvantages.
- In view of the above, the disclosure intends to provide a touch panel integrated with an NFC antenna, which may prevent abrasion or misalignment at a wiring junction of the antenna and is advantageous to ensure the quality of an antenna signal. In addition, an electronic product having the touch panel described above transmits a signal from a touch surface, and thus a selection of a material for a housing is not limited by the NFC antenna.
- To solve the above technical problems, a technical solution provided in the disclosure is as follows. A touch panel integrated with an NFC antenna is provided. The NFC antenna is provided on the touch panel and is connected to a mainboard with a control chip.
- Preferably, the touch panel includes touch panel lens and a touch panel sensor. The touch panel lens and the touch panel sensor having a separated “Lens+TP sensor” structure or have an integrated one glass solution (OGS) structure; and the NFC antenna is provided on the touch panel lens, the NFC antenna is led to an output circuit of the touch panel via the touch panel sensor, or the NFC antenna is directly led to the output circuit of the touch panel.
- Preferably, the NFC antenna is provided between the touch panel lens and the touch panel sensor and is located at borders.
- Preferably, a Black Matrix is printed at borders of an inner surface of the touch panel lens to form a black and opaque border of the touch panel.
- Preferably, the NFC antenna is provided at borders of an outer surface of the touch panel lens and is covered with an insulation protective film; or the NFC antenna is provided at borders of an outer surface of the touch panel sensor and is covered with an insulation protective film.
- Preferably, the NFC antenna is led to the output circuit by being electrically connected to the touch panel sensor via a conductive material, or the NFC antenna is directly led to the output circuit.
- Preferably, the NFC antenna is made from multiturn coils formed by a conductive material wiring.
- Preferably, the NFC antenna is formed with a wiring by low resistivities materials including silver, copper and aluminum.
- Preferably, the multiturn coils are wound to have an annular shape matching with an outline of a product.
- Preferably, the multiturn coils are wound to have a rectangle shape or a circular shape.
- Preferably, a side of the multiturn coils closer to an inner side of the touch panel is covered with a layer of transparent ferrite material.
- As compared with conventional technologies, in the touch panel integrated with the NFC antenna provided in the present disclosure, the NFC antenna is directly provided on the touch panel, and functions of touch-control and the NFC antenna are integrated. Since the touch panel is an essential portion of nowaday electronic products, particularly, is essential to mobile phone products, and the touch panel is located on the outermost of the electronic product, it is advantageous for the antenna to receive and transmit signals. Since the touch panel itself is a component without needs of disassembly and assembly, the conventional problems of abrasion or misalignment at a wiring junction are avoided during the usage of the NFC antenna. Furthermore, a solution is provided for advantageously receiving an NFC signal from a touch surface of the touch panel, or for a case that the NFC signal must be received from the touch surface of the touch panel. In addition, a signal is transmitted at the touch surface in an electronic product having the touch panel described above, and thus the selection of materials for a housing is not limited by the NFC antenna.
