如图1所示，该显示屏驱动系统100包括显示屏120和主板140；其中，主板140上设有驱动芯片160，驱动芯片160通过柔性线路板180电连接显示屏120以驱动显示屏120进行显示。
本发明提供的显示屏驱动系统100由于设有主板140和驱动芯片160，将驱动芯片160设置在主板140上而不是柔性线路板180上，降低元器件占据显示区的空间，从而达到显示屏120的上下窄边框，进而提升显示屏120的屏占比。
请一并参阅图2，显示屏120包括显示区122和非显示区124，非显示区124设置在显示区122的下方，非显示区124包括依次设置的引线单元1242、分路器单元1244、测试单元1246及扇出单元1248。
其中，显示区122的子像素电连接引线单元1242，引线单元1242电连接分路器单元1244，分路器单元1244和测试单元1246分别电连接扇出单元1248，扇出单元1248电连接驱动芯片160。
具体的，引线单元1242具体包括与显示区122子像素连接的信号线，在一些实施例中，还包括部分虚拟子像素，虚拟子像素不用于显示作用，信号线包括扫描线或者数据线或者两者组合，多条信号线通过复用分路器可以大大减少信号线的数量，从而将引线单元1242变换为分路器单元1244，然后，分路器单元1244和测试单元1246分别电连接至扇出单元1248，扇出是PCB中一种常用的设计，即将某个元器件引脚走出一小段线，再打一个过孔结束的过程，尤其适用于密度大、引脚众多的线路设计中；最终，扇出单元1248电连接驱动芯片160。
在本发明实施例所提供的显示屏120中，减少了驱动芯片160以及与驱动芯片160电连接的元器件，使得显示屏120的下边框的宽度变窄，因为显示屏120省去了驱动芯片160，不用将全部信号线挤进比较窄的驱动芯片160里，所以扇区单元1248的走线弯曲角度可以不用太大，其宽度可以变得更窄，使得显示屏120的下边框的宽度进一步变窄，可以实现显示屏120的下边框的宽度变窄50%左右，从而提升屏占比。
具体来说，柔性线路板180包括柔性线路板主体182、柔性线路板第一连接区184以及柔性线路板第二连接区186，其中，扇出单元1248与柔性线路板第一连接区184通过绑定技术电连接，驱动芯片160与柔性线路板第二连接区186通过绑定技术或连接器电连接。具体的，连接器为顶针式连接器，尤其是引脚足够多的顶针式连接器；绑定技术的材料为异方性导电膜，异方性导电膜是利用导电粒子连接柔性线路板180与显示屏140或驱动芯片160两者之间的电极使之成为导通，异方性导电膜(ACF)具有可以连续加工且极低材料损失的特性，使得它成为目前较普遍使用的产品形式。
柔性线路板180为双面柔性线路板，具体是将信号线从柔性线路板第一连接区184引出后，透过挖孔将一半的信号线分别引至两层，可以减少柔性线路板的面积，降低成本。
在本发明实施例所提供的显示屏驱动系统100中，省去了FPCA，换成柔性线路板180将显示屏120和主板140进行电气连接，将驱动芯片160集成在主板140上，提高了主板140的集成度，从而增加了电路的稳定性。
请参阅图3，图3是本发明提供的显示屏驱动系统第二实施例的结构示意图。
如图3所示，该显示屏驱动系统200的主板240上还包括主控芯片250，主控芯片250与驱动芯片260电连接，主控芯片250用于接收视频信号，并解析视频信号以得到驱动信号及时序信号；驱动芯片260用于接收驱动信号及时序信号，并根据驱动信号及时序信号驱动显示屏220进行显示，主控芯片250与驱动芯片260通过P2P或者I2C总线进行通信。
本实施例中，主板240上进一步设有稳压电源电路242，稳压电源电路242与驱动芯片260电连接，稳压电源电路242为驱动芯片260提供稳压电源，主板240上进一步设有滤波电路244，滤波电路244与稳压电源电路242电连接，滤波电路244为稳压电源电路242提供滤波作用；其中，稳压电源电路242和滤波电路244均由电容、电阻、电感以及二极管等元器件构成；在其他实施例中，还可以将稳压电源电路242和滤波电路244设计在一起，合并为一个电路。
请参阅图4，图4是本发明提供的显示屏驱动系统第三实施例的结构示意图。
如图4所示，该显示屏驱动系统300包括显示屏320和主板340；其中，主板340上设有主控芯片350，主控芯片350通过柔性线路板380电连接显示屏340，且驱动显示屏340进行显示。主板340上进一步设有稳压电源电路342，稳压电源电路342与主控芯片350电连接，稳压电源电路342为主控芯片350提供稳压电源；主板340上进一步设有滤波电路344，滤波电路344与稳压电源电路342电连接，滤波电路344为稳压电源电路342提供滤波作用。
本实施例的结构与第二实施例的结构基本相同，不同的是，主控芯片350将主控芯片250与驱动芯片260的功能合二为一，使得该显示驱动系统300更加一体化，集成度更高，从而进一步增加了电路的稳定性。
其中，主控芯片和驱动芯片的功能和结构参见上文，此处不再赘述。
请参阅图5，图5是本发明提供的窄边框移动终端一实施例的结构示意图。
如图5所示，该移动终端10，包括移动终端主体11以及上述的显示屏驱动系统100。
其中，显示屏驱动系统100的结构参见上文，此处不再赘述。
综上所述，本领域技术人员容易理解，本发明提供的显示屏驱动系统由于设有主板和驱动芯片，将驱动芯片设置在主板上而不是柔性线路板上，降低元器件占据显示区的空间，从而达到显示屏的上下窄边框，进而提升显示屏的屏占比。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
