伴随着市场的不断发展，液晶显示技术与触控技术不断提高，用户对手机、平板电脑等外观设计提出了更苛刻的要求。屏占比是指显示设备的显示区面积与整体表面面积的比例，屏占比对显示设备的外观整体效果影响较大，高的屏占比使显示设备整体感更强，更受用户喜爱。
内嵌式触控(In-cell touch)技术依靠良好的触控效果与较低的厚度也开始越来越多的应用到手机等显示产品中。对于液晶显示器(Liquid Crystal Display，LCD)，触控电路结构既可以集成在阵列基板(Thin Film Transistor，TFT)侧，也可以集成在彩膜基板侧(Color Filter，CF)侧。提高采用内嵌式触控电路的液晶显示器的屏占比的方法一般是缩窄显示设备的上、左、右边框的尺寸，若再搭配整机玻璃盖板设计甚至可以实现三边无边框的视效。目前的窄边框设计基本上已将左、右、上边框的周边电路压缩到了极致(如最窄的边框已经压缩到了0.3mm)。
现有技术中，显示设备的下边框通常采用集成电路(Integrity Circuit，IC)组合柔性电路板(Flexible Print Circuit Board，FPC)的设计方案，虽然通过压缩相关走线以及相关的电路功能单元的尺寸可以起到缩小边框的效果，但对下边框可缩减的幅度有限，下边框尺寸仍然较大，导致屏占比较低，影响用户体验。

本实施例中，阵列基板40包括显示区12和非显示区14，非显示区14位于显示区12的边缘。具体的，显示区12的边缘与阵列基板40的边缘之间均为非显示区14，由于显示区12位于阵列基板40的中心位置，非显示区14为围绕显示区12的框型区域。进一步的，彩膜基板80与阵列基板40层叠设置，彩膜基板80的尺寸小于阵列基板40的尺寸，彩膜基板80在阵列基板40的垂直投影未覆盖的部分形成外接线路绑定区142(Outer Lead Bonding，OLB)，本申请实施例所指的非显示区14可以为下绑定区，即外接线路绑定区142所在一侧的非显示区14。本实施例中，非显示区14包括外接线路绑定区142和走线区144，走线区144为彩膜基板80靠近外接线路绑定区142的边缘在阵列基板40的垂直投影与显示区12的边缘之间的区域。

封装于覆晶薄膜20上的集成电路24集成了显示和触控功能，集成电路24通过栅极线或数据线电连接至栅极线或数据线及触控电极60实现了显示和触控功能，覆晶薄膜20的固定端220搭接在非显示区14(外接线路绑定区142)，集成电路24位于阵列基板40外的承载区222，相较于现有技术在非显示区14设置区域绑定集成电路24和柔性电路板，本申请实施例提供的内嵌式触控面板仅有固定端220(覆晶薄膜绑定区域140占用宽度如图1所示宽度b)和连接固定端220与显示区12的区域(连接线30占用宽度如图1所示宽度a)占用边框14尺寸，集成电路24不占用非显示区14尺寸，集成电路24与覆晶薄膜20的连接走线也不占用非显示区14尺寸，从而减小了非显示区14(外接线路绑定区142)的尺寸，提高了显示设备的屏占比，提高了用户体验。
本实施例中，固定在覆晶薄膜绑定区域140的覆晶薄膜20通过连接线30电连接至栅极线或数据线和触控电极60。具体到图4，覆晶薄膜20的固定端220包括依次交错排列的第一引脚262和第二引脚264，第一引脚262和第二引脚264通过覆晶薄膜绑定区域140上的传输引脚150电连接连接线30，其中，第一引脚262传输扫描信号或数据信号，第二引脚264传输触控信号。本实施例中，第一引脚262和第二引脚264通过覆晶薄膜绑定区域140上的传输引脚150电连接连接线30，具体的，传输引脚150包括交错排列的第一传输引脚1502和第二传输引脚1504，第一传输引脚1502通过连接线30电连接栅极线或数据线，第二传输引脚1504通过连接线30电连接触控电极60。覆晶薄膜20绑定至覆晶薄膜绑定区域140后，第一引脚262对应连接第一传输引脚1502，第二引脚264对应连接第二传输引脚1504，从而使第一引脚262电 连接至栅极线或数据线，第二引脚264通电连接至触控电极60。一种实施方式中，连接线30包括第一连接线302和第二连接线304，第一连接线302的一端电连接至第一引脚262，另一端电连接至栅极线或数据线；第二连接线304的一端电连接至第二引脚264，另一端电连接至触控电极60。具体的，连接线30为图案化的金属层形成金属线，一种实施方式中，连接线30可以为Mo、Mo/Al/Mo、Ti/Al/Ti、或者Cu。

本实施例中，覆晶薄膜绑定区域140内的多个传输引脚150中，每一用于接收触控信号的传输引脚150均设于相邻两用于接收扫描信号或数据信号的传输引脚150之间；或每一用于接收扫描信号或数据信号的传输引脚150均设于相邻两用于接收触控信号的传输引脚150之间。
具体到图3，覆晶薄膜绑定区域140靠近非显示区14居中的位置，即覆晶薄膜20固定于非显示区14居中的位置，由于覆晶薄膜20的水平尺寸小于显示区12的水平尺寸，连接传输引脚150的连接线30需要经过弯折。一种实施方式中，连接线30包括第一连接线32和第二连接线34，第一连接线32电连接第一传输引脚1502与栅极线或数据线，第二连接线34电连接第二传输引脚1504与触控电极60。若第一引脚262与栅极线或数据线的水平距离过大，为了保证走线区144能够容纳下所有第一连接线32且第一连接线32不易断裂，需要增大第一引脚262与栅极线或数据线的竖直距离，以减小第一连接线32的弯折幅度，导致走线区144的尺寸增大；若第二引脚264与触控电极60的水平距离过大，为了保证走线区144能够容纳下所有第二连接线34且第二连接线34不易断裂，需要增大第二引脚264与触控电极60的竖直距离，以减小第二连接线34的弯折幅度，导致走线区144的尺寸增大。本实施例中，第一传输引脚1502与第二传输引脚1504交错排列，对应的第一引脚262与第二引脚264交错排列，降低了第一传输引脚1502与栅极线或数据线的水平距离及第二传输引脚1504与触控电极60的水平距离，对应减小了第一引脚262与栅极线或数据线的竖直距离及第二引脚264与触控电极60的竖直距离，从而减小了走线区144的尺寸，即减小了非显示区14的尺寸，提高了屏占比。

本实施例中，栅极线和数据线相交形成多个子像素区域，每一子像素区域内都设有薄膜晶体管和像素电极，栅极线或数据线包括数据线，第一连接线32连接数据线，从而通过薄膜晶体管电连接至像素电极。一种实施方式中，薄膜晶体管包括源极、漏极及栅极，栅极电连接扫描线从而电连接至扫描连接线，扫描连接线发送扫描信号控制源极与漏极的通断状态，漏极电连接第一连接线32，源极电连接像素电极，当漏极与源极导通时，第一连接线32传递数据信号控制像素电极的像素电压。
