Patent Application
20150049262
The subject matter herein generally relates to a flexible touch panel structure and an electronic watch using the same.
Flexible touch panels are widely used in electronic products. For example, a flexible touch panel can be assembled in an electronic watch. In a conventional process of assembling the electronic watch, a flexible touch panel, a circuit electrically coupled to the flexible touch panel, and a thin-film battery are provided respectively and then assembled in the electronic watch.
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of the present disclosure.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape or other word that substantially modifies, such that the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
The thin-film battery 111 can include an encapsulation layer 1111, a cathode connecting layer 1112, a cathode layer 1113, an electrolyte layer 1114, an anode layer 1115, an FPC (Flexible Printed Circuit) connecting layer 1116, and a ground layer 1117 stacked in order. The encapsulation layer 1111 can be formed in the bottom of the assembly portion 31. An area of the cathode connecting layer 1112 can be substantially equal to an area of the encapsulation layer 1111. The cathode layer 1113, the electrolyte layer 1114, and the anode layer 1115 can have a substantially same area smaller than the area of the cathode connecting layer 1112.
The thin-film battery 111 can further include a sealing layer 1118 and a connecting layer 1119. The sealing layer 1118 can be substantially annular and positioned around the cathode layer 1113, the electrolyte layer 1114 and the anode layer 1115 stacked in order. The top and bottom ends of the sealing layer 1118 can be in tight contact with the FPC connecting layer 1116 and the cathode connecting layer 1112. The connecting layer 1119 can be positioned on one side of the sealing layer 1118. The two ends of the connecting layer 1119 can be electrically connected to the cathode connecting layer 1112 and the FPC connecting layer 1116, and the potential of the cathode connecting layer 1112 can be fed into the FPC connecting layer 1116. The anode layer 1115 can be electrically coupled to the FPC connecting layer 1116, and the potential of the anode layer 1115 can be fed into the FPC connecting layer 1116. One end of the FPC connecting layer 1116 can extend out of the connecting layer 1119 and equipped with electric pins 11161 electrically coupled to the anode layer 1115 and the cathode connecting layer 1112. The ground layer 1117 and the FPC connecting layer 1116 can be separated by a prepreg layer (not labeled).
The touch module 113 can include a FPC touch signal layer 1131 and a FPC touch pad layer 1133. The flexible touch panel structure 11 can further include a solder mask layer 1135 on the top of the FPC touch pad layer 1133. Areas of the FPC touch signal layer 1131, the FPC touch pad layer 1133, and the solder mask layer 1135 can be substantially equal to that of the ground layer 1117. The FPC touch signal layer 1131 can be laminated on the ground layer 1117 with a prepreg layer (not labeled) interposed therebetween. The FPC touch pad layer 1133 can be laminated on the FPC touch signal layer 1131 with a prepreg layer (not labeled) interposed therebetween. The FPC connecting layer 1116, the ground layer 1117, the FPC touch signal layer 1131, and the FPC touch pad layer 1133 are electrically coupled by wires (not shown).
The display module 115 can cover the solder mask layer 1135, used to display images. The display module 115 can be exposed to outside of the assembly portion 31.
In operation, the thin-film battery 111 can supply power to the flexible touch structure 11 by the electric pins 11161, the FPC touch signal layer 1131 can be electrically connected to the FPC touch pad layer 1133, and the display module 115 can display images, such as time, date, and other informations.
In other embodiments, the FPC touch signal layer 1131 can be positioned on one side of the FPC connecting layer 1116, and the flexible structure 11 can be more thinner.
In at least one embodiment, as the FPC connecting layer 1116, the ground layer 1117, the FPC touch signal layer 1131, and the FPC touch pad layer 1133 can be formed in one multilayer FPC and made in one process, the flexible touch structure 11 and the electronic watch 100 can be thin, and the flexibility can be increased.
The embodiments shown and described above are only examples. Many details are often found in the art such as the other features of a flexible touch panel structure and an electronic watch. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, comprising in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above may be modified within the scope of the claims.
