结合图20，柔性电路板24连接于显示屏22的边缘，具体的，柔性电路板24由显示屏22的长度方向L的一端引出并弯折后层叠于非显示面22b上。柔性电路板24上可以设有显示驱动芯片242，并且柔性电路板24可以连接至主板26，从而控制显示屏22显示图像。一种实施方式中，显示驱动芯片242固定在柔性电路板24背离显示屏22的一侧，显示驱动芯片242的引脚插接或焊接在柔性电路板24对应的触点上。
请参阅图20和图21，电路板设置于柔性电路板24背离显示屏22的一侧，并且显示驱动芯片242全部位于或者部分位于第一通孔2420内。具体的，第一通孔2420为贯穿电路板的孔，即第一通孔2420为电路板上镂空的部分。显示驱动芯片242可以全部或者部分穿过第一通孔2420，一种实施方式中，显示驱动芯片242的厚度大于电路板的厚度，显示驱动芯片242全部穿过第一通孔2420，另一种实施方式中，显示驱动芯片242的厚度小于电路板的厚度，显示驱动芯片242部分穿过第一通孔2420。第一通孔2420使电路板和显示驱动芯片242在移动终端300的厚度方向上部分重叠，减小了移动终端300的厚度尺寸，有利于移动终端300的轻薄化设计。
请参阅图20、图21及图22，电路板包括主板26和副板28，主板26上设有处理器262，移动终端300包括电池210，副板28、电池210及主板26在显示屏22的长度方向L上依次排列，第一通孔2420设置于主板26上。具体的，主板26为集成有功能器件的电路板，例如处理器262，处理器262为负责移动终端300的运算、处理等功能的芯片。副板28为集成有一定的功能器件的电路板，副板28用于辅助主板26，主板26与副板28分开设置，以将移动终端300的功能器件分开设置。电池210用于向显示屏22、主板26及副板28上的功能器件供电。

请参阅图21和图22，本实施例中，在显示屏22的长度方向L上，主板26的尺寸大于副板28的尺寸，且柔性电路板24的尺寸大于副板28的尺寸，即主板26的尺寸和柔性电路板24的 尺寸均大于副板28的尺寸。在显示屏22的长度方向L上，副板28、电池210及主板26依次排列，并且主板26层叠设置于柔性电路板24背离显示屏22的一侧，换言之，在显示屏22的长度方向L上，尺寸较大的主板26和柔性电路板24位于电池210的同一侧，尺寸较小的副板28位于电池210的另一侧。主板26和柔性电路板24至少部分重叠，在显示屏22的长度方向L上，主板26和柔性电路板24占用的总空间为主板26或柔性电路板24的尺寸，且主板26的尺寸和柔性电路板24的尺寸均大于副板28的尺寸，副板28占用的空间小，最小化了主板26、柔性电路板24及副板28在显示屏22的长度方向L上占用的总空间，从而增大了用于放置电池210的空间，增大电池210的尺寸会对应增大电池210的容量，有利于提高移动终端300的待机时间。
请参阅图20和图21，本实施例中，移动终端300包括受话器，受话器位于显示屏22的非显示面22b一侧，在显示屏22的长度方向L上，副板28和受话器位于电池210的同一侧。具体的，受话器用于发出声音，用户接打电话时，移动终端300的受话器一端靠近耳朵，以向用户传递声音信息。一种实施方式中，受话器为压电陶瓷，以振动发声，显示屏22无需开孔，有利于提高屏占比。本实施例中，以受话器所在的一端为移动终端300的上端，与上端相对的一端为下端，则副板28位于上端，主板26位于下端，电池210位于上端与下端之间。
请参阅图20，本实施例中，副板28上设有避让孔230，受话器全部位于或部分位于避让孔230内。具体的，避让孔230为副板28上镂空的部分，受话器通过避让孔230穿过副板28。避让孔230使副板28和受话器在移动终端300的厚度方向上部分重叠，减小了移动终端300的厚度尺寸，有利于移动终端300的轻薄化设计。
本实施例中，移动终端300的厚度大于等于3mm且小于等于4mm。移动终端300及移动终端300的整体厚度较小，有利于轻薄化设计。
