Transparent, but in view of making the first frame portion 212 conductive and transparent, the first frame portion 212 can be made into an opaque conductive layer, and the metal mesh structure of the second window portion 311 can also be processed. For example, the metal wire in the metal mesh structure is made into a nano-scale wire, and the second window portion 311 is transparent and electrically conductive. Since the first window portion 211 is disposed corresponding to the second window portion 311, the first window portion 211 and the second portion. The window portion 311 is for displaying the content on the display screen.
在本实施例中，第一导电层为金属涂层，第二导电层为金属网状结构，但能实现透明导电功能的涂层材料均可作为第一导电层的材料，同时第二导电层根据触控屏的具体情况，还可设置为其他可接收信号的结构。In this embodiment, the first conductive layer is a metal coating layer, and the second conductive layer is a metal mesh structure, but a coating material capable of realizing a transparent conductive function can be used as the material of the first conductive layer, and the second conductive layer According to the specific conditions of the touch screen, it can also be set as other structures that can receive signals.
如图5及图6所示，触控屏还包括引线700与柔性电路板600，引线700设于第二边框部312，柔性电路板600的一端设于第二边框部312，并与引线700的一端连接，第一基材220与第二导电层310贴合连接，引线700将接收极线路层300所接收的信号传递至柔性电路板600，再由柔性电路板600处理并传出，由于柔性电路板600是通过压合工艺
设于发射极线路层200与接收极线路层300之间，且柔性电路板600通过引线700与接收极线路层300的第二导电层310连接，因此接收极线路层300的第二导电层310与发射极线路层200的第一基材220贴合连接，并夹持柔性电路板600的一端。As shown in FIG. 5 and FIG. 6 , the touch screen further includes a lead 700 and a flexible circuit board 600. The lead 700 is disposed on the second frame portion 312. One end of the flexible circuit board 600 is disposed on the second frame portion 312 and is connected to the lead 700. The first substrate 220 is connected to the second conductive layer 310. The lead 700 transmits the signal received by the receiving circuit layer 300 to the flexible circuit board 600, and is processed and transmitted by the flexible circuit board 600. The flexible circuit board 600 is through a press-bonding process
Provided between the emitter line layer 200 and the receiver line layer 300, and the flexible circuit board 600 is connected to the second conductive layer 310 of the receiver line layer 300 through the lead 700, and thus the second conductive layer 310 of the receiver line layer 300 The first substrate 220 of the emitter wiring layer 200 is attached and bonded to one end of the flexible circuit board 600.
基板100、第一基材220与第二基材320均为透明件，且为柔性导电材料。由于在电容屏中，触控屏的下方还设置有显示屏，因此要求触控屏的部件应全部或部分为透明件，使使用者能透过触控屏看到显示屏上的内容，此外，为实现触控屏可弯折的特性，基板100、第一基材220与第二基材320均为柔性材料，并可导电。The substrate 100, the first substrate 220 and the second substrate 320 are both transparent members and are flexible conductive materials. Since the display screen is provided under the touch screen in the capacitive screen, the components of the touch screen are required to be transparent or all of the components, so that the user can see the content on the display through the touch screen. In order to realize the characteristics that the touch screen can be bent, the substrate 100, the first substrate 220 and the second substrate 320 are both flexible materials and can be electrically conductive.
在本实施例中，第一视窗部211与第一边框部212分别位于第一导电层210的两端，由于第一导电层210为金属涂层，可传导电流，无需在第一视窗部211的侧边上设置导线，此时第一视窗部211为透明结构，又由于第一基材220为透明件，第一导电层210在第一视窗部211覆盖的区域内为透明无边框的结构，但第一视窗部211与第一边框部212在第一导电层210上的分布方式包括但不限于上述方式，还可为第一边框部212包围第一视窗部211等，同时第二视窗部311、第二边框部312的分布方式与第一视窗部211、第一边框部212的分布方式相同。In this embodiment, the first window portion 211 and the first frame portion 212 are respectively located at two ends of the first conductive layer 210. Since the first conductive layer 210 is a metal coating layer, current can be conducted without being in the first window portion 211. The wire is disposed on the side of the first window portion 211, and the first substrate 220 is a transparent member. The first conductive layer 210 is a transparent frameless structure in the region covered by the first window portion 211. The first window portion 211 and the first frame portion 212 are distributed on the first conductive layer 210, but are not limited to the above manner, and the first frame portion 212 may surround the first window portion 211 and the like, and the second window. The distribution of the portion 311 and the second frame portion 312 is the same as that of the first window portion 211 and the first frame portion 212.
如图1及图2所示，触控屏还包括光学胶400与盖板500，盖板500、光学胶400、发射极线路层200、接收极线路层300与基板100由上往下依次叠设；或盖板500、光学胶400、接收极线路层300、发射极线路层200与基板100由上往下依次叠设。盖板500用于防护接收极线路层300与发射极线路层200，光学胶400用于黏合盖板500与触控屏的其他部分，接收极线路层300与发射极线路层200位于盖板500与基板100之间，接收极线路层300与发射极线路层200相对位置的调换不影响两者的功能。As shown in FIG. 1 and FIG. 2, the touch screen further includes an optical adhesive 400 and a cover plate 500. The cover plate 500, the optical adhesive 400, the emitter circuit layer 200, the receiver circuit layer 300, and the substrate 100 are stacked from top to bottom. Or the cover 500, the optical adhesive 400, the receiver wiring layer 300, the emitter wiring layer 200, and the substrate 100 are sequentially stacked from top to bottom. The cover plate 500 is used to protect the receiver circuit layer 300 and the emitter circuit layer 200. The optical glue 400 is used to bond the cover plate 500 and other portions of the touch screen. The receiver circuit layer 300 and the emitter circuit layer 200 are located on the cover plate 500. The exchange of the relative positions of the receiver line layer 300 and the emitter line layer 200 with the substrate 100 does not affect the functions of both.
接收极线路层300及发射极线路层200的厚度之和小于或等于55μm，盖板500、光学胶400、接收极线路层300、发射极线路层200与基板100的厚度之和小于或等于200μm。上述触控屏只设置一个基板100，因此厚度较小，耐弯折性好，相对于将第一导电层210与第二导电层310设为同一个导电层，增加的接收极线路层300厚度仅为5-15μm，但由于接收极线路层300与发射极线路层200分开设置，减少了上述两者之间的干扰，提高了触控屏的精度。The sum of the thicknesses of the receiving circuit layer 300 and the emitter circuit layer 200 is less than or equal to 55 μm, and the sum of the thicknesses of the cover 500, the optical adhesive 400, the receiving wiring layer 300, the emitter wiring layer 200 and the substrate 100 is less than or equal to 200 μm. . The touch screen is only provided with one substrate 100, so the thickness is small and the bending resistance is good. The thickness of the receiving layer 3 is increased with respect to the first conductive layer 210 and the second conductive layer 310 being the same conductive layer. It is only 5-15μm, but since the receiving circuit layer 300 is separately disposed from the emitter circuit layer 200, the interference between the two is reduced, and the precision of the touch screen is improved.
在本实施例中，为保证触控屏拥有更好的耐弯折性能及实现无边框的效果，将接收极线路层300与发射极线路层200的厚度设置为小于或等于55μm，同时盖板500、光学胶400、接收极线路层300、发射极线路层200与基板100的厚度之和设置为小于或等于200μm，但考虑到降低成本及对触控屏性能的其他要求，也可将接收极线路层300与发射极线路层200的厚度之和设置为大于55μm，同时盖板500、光学胶400、接收极线路层300、
发射极线路层200与基板100的厚度之和设置为大于200μm。In this embodiment, in order to ensure that the touch screen has better bending resistance and a non-border effect, the thickness of the receiving circuit layer 300 and the emitter circuit layer 200 is set to be less than or equal to 55 μm, and the cover is 500, the optical adhesive 400, the receiving circuit layer 300, the sum of the thickness of the emitter circuit layer 200 and the substrate 100 are set to be less than or equal to 200 μm, but can also be received in consideration of cost reduction and other requirements for the performance of the touch screen. The sum of the thicknesses of the polar wiring layer 300 and the emitter wiring layer 200 is set to be greater than 55 μm, while the cover 500, the optical adhesive 400, the receiving wiring layer 300,
The sum of the thicknesses of the emitter wiring layer 200 and the substrate 100 is set to be larger than 200 μm.
