进一步地，由于基板10的材料不同，进而对金属膜层的制程兼容性不同，其中，当基板10为玻璃基板时，其对金属膜层的兼容性较低，因此制备于其上的金属膜层的膜层也不宜过厚，如图3所示；而当基板10的材料为上述有机高分子材料中，其对金属膜层的兼容性较高，因此制备于其上的金属膜层的厚度也相对较厚，如图4所示，且厚度大于玻璃基板上的金属膜层厚度。例如，当基板10为玻璃基板时，制备于其上的金属膜层（可包括电磁感应线圈21和发光信号线22）的厚度大于或等于0.1微米，且小于或等于50微米；当基板10的材料包括上述有机高分子材料时，制备于其上的金属膜层（可包括电磁感应线圈21和发光信号线22）的厚度大于或等于1微米，且小于或等于100微米。
优选的，当基板10为玻璃基板时，制备于其上的金属膜层（可包括电磁感应线圈21和发光信号线22）的厚度大于或等于0.5微米，且小于或等于3微米；当基板10的材料包括上述有机高分子材料时，制备于其上的金属膜层（可包括电磁感应线圈21和发光信号线22）的厚度大于或等于20微米，且小于或等于60微米。
在本申请实施例中，电磁感应线圈21包括沿第一方向X排列且沿第二方向Y延伸的多个第一电磁感应线圈211，以及沿第二方向Y排列且沿第一方向X延伸的多个第二电磁感应线圈212，且第一方向X与第二方向Y相交。可选的，第一方向X与第二方向Y相垂直。
此外，显示模组包括触控区101，且每一第一电磁感应线圈211包括第一端部2111、第二端部2112以及连接于第一端部2111与第二端部2112之间的第一绕线部2113，且第一绕线部2113位于触控区101内，每一第二电磁感应线圈212包括第三端部2121、第四端部2122以及连接于第三端部2121与第四端部2122之间的第二绕线部2123，且第二绕线部2123位于触控区101内。
其中，请结合图1、图2、图5以及图6，每一第一绕线部2113围绕对应一第一电磁感应区1011设置，每一第二绕线部2123围绕对应的一第二电磁感应区1012设置，进而在触控区101内形成有沿第一方向X排列的多个第一电磁感应区1011以及沿第二方向Y排列的多个第二电磁感应区1012，且任一第一电磁感应区1011与任一第二电磁感应区1012之间交叉设置并部分重叠。
可选内的，沿第一方向X相邻的两个第一电磁感应区1011之间部分重叠，沿第二方向Y相邻的两个第二电磁感应区1012之间部分重叠。
在本申请实施例中，第一绕线部2113呈螺旋状绕对应的一第一电磁感应区1011设置，第二绕线部2123呈螺旋状绕对应的一第二电磁感应区1012设置，其中，第一绕线部2113围绕对应的第一电磁感应区1011的圈数大于或等于1，第二绕线部2123围绕对应的第二电磁感应区1012的圈数大于或等于1。
请参照图7、图8以及图9，为第一绕线部2113围绕对应的第一电磁感应区1011的圈数大于1，以及第二绕线部2123围绕对应的第二电磁感应区1012的圈数大于1对应的电磁感应线圈21的分布示意图。可以理解的是，随着第一绕线部2113与第二绕线部2123围绕的圈数的增加，在对电磁感应线圈21加载电压后，其产生的磁场也越强。
具体地，电磁感应层20包括沿第二方向Y相对设置的第一侧与第二侧，以及沿第一方向X相对设置的第三侧和第四侧，其中，发光背板还包括设置于基板10上并位于第一侧的多个第一输入端子与多个第一输出端子，每一第一电磁感应线圈211的第一端部2111连接于对应的一第一输入端子，每一第一电磁感应线圈211的第二端部2112对应连接于对应的一第一输出端子。
发光背板还包括设置于基板10上的并位于第三侧的多个第二输入端子与多个第二输出端子，每一第二电磁感应线圈212的第三端部2121连接于对应的一第二输入端子，每一第二电磁感应线圈212的第四端部2122连接于对应的一第二输出端子。
可选的，各第一电磁感应线圈211的第一绕线部2113在第二侧电性连接，各第二电磁感应线圈212的第二绕线部2123在第四侧电性连接，以提高触控区101内边缘区域的触控精度，且可以缩减边框宽度。
具体地，当各第一绕线部2113在第二侧电性连接时，如图10中a所示，各第一绕线部2113在第二册处为平齐分布，可实现缩减边框宽度，且长短相同，则各第一绕线部2113的阻抗也相同，进而产生的信号强度也相同，以提高电磁感应层20的感测精度。当各第一绕线部2113在第二侧为绝缘设置时，如图10中b所示，进而各第一绕线部2113在第二侧处不相平齐，且由上往下，各第一绕线部2113的长度增加，进而会增加显示模组的边框宽度，不利于窄边框显示，另外，各第一绕线部2113的长度不同，进而阻抗也不同，其产生的信号强度也不相同，将影响电磁感应层20的感测精度。可以理解的是，本申请实施例中仅示出第一电磁感应线圈211的排布为例进行说明，而第二电磁感应线圈212同理。
进一步地，在本申请实施例中，发光器件层30包括沿第一方向X与第二方向Y呈阵列分布的多个发光器件31，可选的，发光器件31可为mini LED灯件或Micro-LED灯件。第一绕线部2113与第二绕线部2123的走线延伸路径皆可设置于相邻的发光器件31之间，即第一绕线部2113与第二绕线部2123皆可围绕多个发光器件31设置。
具体地，发光器件层30包括沿第一方向X排列的多个第一发光器件组以及沿第二方向Y排列的多个第二发光器件组，每一第一发光器件组包括沿第二方向Y排列的多个发光器件31，每一第二发光器件组包括沿第一方向X排列的多个发光器件31。
其中，每一第一电磁感应区1011内设有沿第一方向X排列的至少一第一发光器件组，每一第二电磁感应区1012内设有沿第二方向Y排列的至少一第二发光器件组。即每一第一电磁感应区1011内设有沿第一方向X排列的至少一行发光器件31，每一第二电磁感应区1012内设有沿第二方向Y排列的至少一列发光器件31。
在本申请实施例中，每一第一电磁感应线圈211围绕多行发光器件31，每一第二电磁感应线圈212围绕多列发光器件31，且每一行发光器件31皆对应设置一第一输入端子和一第一输出端子，每一列发光器件31皆对应设置一第二输入端子和一第二输出端子，而本申请实施例提供的图示仅画图部分输入端子、输出端子以及部分电磁感应线圈21以作为示例。
进而在电磁感应线圈21的驱动过程中，可由上往下沿第一方向X依次向各第一输入端子加载电压，即先对第一行第一发光器件31对应的一第一输入端子通电，同时导通对应的一第一输出端子，使得第一行发光器件31对应的第一电磁感应线圈211产生磁场；然后对第二行第一发光器件31对应的一第一输入端子通电，同时导通对应的一第一输出端子，使得第二行发光器件31对应的第一电磁感应线圈211产生磁场，且对于第一电磁感应线圈211的驱动可沿第一方向X依次进行导通。同理，也可由左往右依次导通向各第二输入端子加载电压，即先对第一列第一发光器件31对应的一第二输入端子通电，同时导通对应的一第二输出端子，使得第一列发光器件31对应的第二电磁感应线圈212产生磁场；然后对第二列第一发光器件31对应的一第二输入端子通电，同时导通对应的一第二输出端子，使得第二列发光器件31对应的第二电磁感应线圈212产生磁场，且对于第二电磁感应线圈212的驱动可沿第二方向Y依次进行导通。
进一步地，在公式Φ=nBS中，Φ为磁通量，n为电磁感应线圈21的围绕圈数，B为产生的磁场强度，S为各电磁感应线圈21的围成面积，由上述公式可知，在触控区101内分布有多个电磁感应线圈21后，可以通过感知各电磁感应线圈21围成区域内的磁通量变化，以感知触控位置。
具体地，请结合图5、图6、图8、图9、图11、图12、图13以及图14，本申请实施例提供的显示模组还可以包括触控件60，例如触控笔等，触控件60用于产生磁场，进而当触控件进行触控时，可改变各电磁感应线圈21所围成区域内的磁通量，当各电磁感应线圈21缩围成区域内的磁通量发生变化时，其电磁感应线圈21中的电压也将发生改变，进而可以得出触控件60的触控位置。
需要说明的是，在本申请实施例中，如图5、图6、图8以及图9所示，各第一绕线部2113沿第一方向X上的宽度d1以及第二绕线部2123沿第二方向Y上的宽度d2皆大于或等于10毫米，且小于或等于80毫米。可以理解的是，第一绕线部2113沿第一方向X上的宽度越大，则第一绕线部2113所围成的第一电磁感应区1011的面积就越大，其内的发光器件31的行数就越多；而第二绕线部2123沿第二方向Y上的宽度越大，则第二绕线部2123所围成的第二电磁感应区1012的面积就越大，其内的发光器件31的列数就越多。
进一步地，当第一电磁感应区1011与第二电磁感应区1012的面积过大时，则会降低触控精度，而当第一电磁感应区1011与第二电磁感应区1012的面积过小时，通过其中的磁通量又很少，导致难以感测。则在本申请实施例中，优选的，各第一绕线部2113沿第一方向X上的宽度d1以及各第二绕线部2123沿第二方向Y上的宽度d2皆大于或等于20毫米，且小于等于50毫米。
需要说明的是，在沿第一方向X上，靠近第三侧处的各第一电磁感应线圈211内发光器件31的行数可为多行，而到第四侧处时，由于已经临近触控区101的边界，因此，最后一行发光器件31对应的一第一电磁感应线圈211内仅围绕该行发光器件31，且倒数第二行发光器件31对应的一第一电磁感应线圈211内可围绕倒数第二行发光器件31以及最后一行发光器件31，即靠近第三侧处的第一电磁感应区1011沿第一方向X上的宽度可以大于靠近第四侧处的第一电磁感应区1011沿第一方向X上的宽度，同理，靠近第一侧处的第二电磁感应区1012沿第二方向Y上的宽度大于靠近第二侧处的第二电磁感应区1012沿第二方向Y上的宽度。
具体地，如图11所示，当触控件60进行触控时，触控件60在靠近显示模组时，其产生的磁场穿过电磁感应层20，使得通过各电磁感应线圈21中的磁通量发生变化；其中，在沿第一方向X上，可以感测出磁通量变化（即感应强度）最大的一第一电磁感应线圈211，而在沿第二方向Y上，也可以感测出磁通量变化最大的一第二电磁感应线圈212，进而在该第一电磁感应线圈211与该第二电磁感应线圈212相交叉重叠的位置，即为触控件60的触控位置A。
可选的，如图12所示，触控件60可为有源触控笔，即触控笔内设置有电源，使其可以产生磁场，进而在触控过程中，通过触控笔产生的磁场引起电磁感应线圈21内磁场的变化，来感测触控笔的触控位置。
可选的，如图13和图14所示，触控笔60可为无源触控笔，即触控笔不能主动产生磁场，可在触控笔内设置一感应线圈，进而在各电磁感应线圈21产生磁场时（如图12），可使得触控笔内的感应线圈切割磁感线，进而可以被动产生磁场（如图13），同样在触控过程中，通过触控笔产生的磁场引起电磁感应线圈21内磁场的变化，来感测触控笔的触控位置。
需要说明的是，由于有源触控笔可以主动产生磁场，进而对于电磁感应线圈21产生的磁场强度要求较小，而无源触控笔需要根据电磁感应线圈21产生的磁场来被动产生磁场，则无源触控笔对于电磁感应线圈21的磁场强度要求较高，则无源触控笔对应的显示模组中电磁感应线圈21的围绕圈数大于有源触控笔对应的显示模组中电磁感应线圈21的围绕圈数。
可选的，有源触控笔对应的显示模组中电磁感应线圈21的围绕圈数为1至5，而无源触控笔对应的显示模组中电磁感应线圈21的围绕圈数为2至10。
另外，在本申请的一种实施例中，请结合图1、图2、图5、图6以及图15，电磁感应层20包括电磁感应线圈21以及发光信号线22，且发光信号线22可电性连接于各发光器件31，以实现发光功能，而电磁感应线圈21可实现电磁感应触控功能，以实现显示模组的集成化。
其中，电磁感应层20还包括设置于基板10上的第一布线子层、设置于第一布线子层上的绝缘层以及设置于绝缘层上的第二布线子层，其中，可将多个第一电磁感应线圈211设置于第一布线子层，多个第二电磁感应线圈212设置于第二布线子层；此外，发光信号线22包括沿第一方向X排列且沿第二方向Y延伸的多个第一信号线221以及沿第二方向排列且沿第一方向X延伸的多个第二信号线222，且多个第一信号线221位于第一布线子层，多个第二信号线222位于第二布线子层。
需要说明的是，当第一电磁感应线圈211与第一信号线221相交叠时，可通过在第二布线子层设置桥接结构，并通过穿过绝缘层的过孔将第一电磁感应线圈211连接起来，以形成回路，或通过穿过绝缘层的过孔将第一信号线221连接起来，以形成回路；同理，当第二电磁感应线圈212与第二信号线222相交叠时，可通过在第一布线子层设置桥接结构，并通过穿过绝缘层的过孔将第二电磁感应线圈212连接起来，以形成回路，或通过穿过绝缘层的过孔将第二信号线222连接起来，以形成回路。
每一发光器件31连接于对应一第一信号线221以及对应一第二信号线222，在本实施例中，多个发光器件31可采用有源矩阵的驱动方式进行驱动，即多个第一信号线221可逐行进行扫描，而多个第二信号线222通入发光信号，以控制每一个发光器件31的亮与暗。
可选的，各第一信号线221与第二信号线222的线宽为10微米至1000微米，优选为200微米至600微米，而每一第一电磁感应线圈的阻抗小于5000欧，对应的线宽5微米至1000微米；优选为100微米至1000微米。
此外，在本实施例中，电磁感应线圈21与发光信号线22可通过同一驱动模组进行驱动，也可分别通过两个驱动模组进行驱动。
例如，发光背板还包括第一驱动模组，且电磁感应线圈21与发光信号线22皆电性连接于第一驱动模组，但是电磁感应线圈21与发光信号线22可采用分时驱动，即电磁感应线圈21在第一时段驱动，而发光信号线22在第二时段驱动，且第一时段与第二时段不重叠。
又例如，发光背板还包括第二驱动模组和第三驱动模组，且电磁感应线圈21电性连接于第二驱动模组，发光信号线22电性连接于第三驱动模组，但是电磁感应线圈21的驱动频率与发光信号线22的驱动频率相异，且电磁感应线圈21的驱动频率与发光信号线22的驱动频率相异无整数倍关系，以防止电磁感应线圈21与发光信号线22之间产生电磁干扰。
且本实施例中各电磁感应线圈21中第一绕线部2113与第二绕线部2123形成的线圈圈数为1圈，产生的磁场相对来说较弱，而本实施例中可采用有源触控笔进行触控。
在本申请的另一种实施例中，请参照图16，本实施例与上一实施例的区别之处在于，各电磁感应线圈21中第一绕线部2113与第二绕线部2123形成的线圈圈数为2圈，产生的磁场相对来说较强，而本实施例中可采用无源触控笔进行触控。
可选的，各第一信号线221与各第二信号线222的线宽为10微米至1000微米，优选地，各第一信号线221与各第二信号线222的线宽为200微米至600微米；各电磁感应线圈21的走线阻抗小于500欧，对应线宽为100微米至3000微米，优选地，对应线宽为400微米至1000微米。

且在本实施例中，各第一绕线部2113与各第二绕线部2123的线圈圈数为1，其产生的磁场强度较弱，而本实施例中可采用有源触控笔进行触控。
可选的，各第一信号线221与各第二信号线222的线宽为10微米至100微米，优选地，各第一信号线221与各第二信号线222的线宽为20微米至60微米；各电磁感应线圈21的走线阻抗小于5000欧，对应线宽为5微米至1000微米，优选地，对应线宽为100微米至1000微米。
在本申请的另一种实施例中，请参照图18，本实施例与上一实施例的区别之处在于，各第一绕线部2113与各第二绕线部2123形成的线圈圈数为2圈，产生的磁场相对来说较强，而本实施例中可采用无源触控笔进行触控。
可选的，各第一信号线221与各第二信号线222的线宽为10微米至100微米，优选地，各第一信号线221与各第二信号线222的线宽为20微米至60微米；各电磁感应线圈21的走线阻抗小于500欧，对应线宽为100微米至3000微米，优选地，对应线宽为400微米至1000微米。
在本申请的另一种实施例中，请参照图19，本实施例与第一个实施例的区别之处在于，本实施例中的多个发光器件31的驱动方式为无源点阵式驱动，其中，发光信号线22包括沿第二方向Y排列且沿第一方向X延伸的多个第三信号线223，且多个第三信号线223可设置于第二布线子层，与多个第二电磁感应线圈212同层设置。此外，每一第三信号线223对应连接于一发光器件31，以驱动使其发光。
在本实施例中，各第一绕线部2113与各第二绕线部2123形成的线圈圈数为1圈，产生的磁场相对来说较强，而本实施例中可采用有源触控笔进行触控。

在本申请的另一种实施例中，请参照图20，本实施例与上一实施例的区别之处在于，各第一绕线部2113与各第二绕线部2123形成的线圈圈数为2圈，产生的磁场相对来说较强，而本实施例中可采用无源触控笔进行触控。
可选的，各第三信号线223的线宽为10微米至100微米，优选地，各第三信号线223的线宽为20微米至60微米；各电磁感应线圈21的走线阻抗小于500欧，对应线宽为100微米至3000微米，优选地，对应线宽为400微米至1000微米。
需要说明的是，本申请仅以上述实施例为例以说明电磁感应线圈21与发光信号线22的排布方式，但并不限于此。
综上所述，本申请实施例通过在发光背板的基板10上设置多个第一电磁感应线圈211以及多个第二电磁感应线圈212，进而可以通过感知显示模组不同位置的电磁感应线圈内的磁通量变化，来得到显示模组触控的坐标，提高了触控效果和触控精度；此外，发光背板的基板10上不需要透光，进而具有大量的空间进行电磁感应线圈的布线，且不会影响到发光背板的发光，对于集成触控功能的显示模组，本申请可以节省显示模组的空间，以提高显示模组的集成化功能。
另外，本申请实施例还提供一种移动终端，该移动终端包括上述实施例中所述的显示模组。
