 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。在图中，结构相似的单元是以相同标号表示。
请参照图3，图3为本发明第一种液晶显示面板中第一种驱动部的结构示意图；
本发明第一种液晶显示面板，譬如为普通驱动方式的液晶显示面板，其包括本体部和驱动部，所述本体部包括多条数据线和多条扫描线，以及由所述数据线和所述扫描线限定的多个像素单元； 以及如图3和图4所示，所述驱动部包括印刷电路板21和柔性连接器22；所述本体部通过所述柔性连接器22与所述印刷电路板21连接；所述驱动部具有多个芯片和电子元件；其中所述多个芯片包括源驱动芯片201、脉冲宽度调制芯片204、可编程伽玛校正缓冲芯片202以及时序控制芯片203；
所述电子元件包括电阻R、电容C、电感L，所述电子元件设置在所述印刷电路板21上；由于将电子元件设置在柔性连接器上，导致电子元件工作不稳定，尤其在柔性连接器上设置电感比较困难，因此将电子元件设置在印刷电路板21上。
所述源驱动芯片201、所述脉冲宽度调制芯片204、所述可编程伽玛校正缓冲芯片202设置在所述柔性连接器上，以减小所述驱动部的空间。
所述印刷电路板21提供视频信号和电源；所述可编程伽玛校正缓冲芯片202对所述印刷电路板21的电源进行脉冲宽度调节，以对所述脉冲宽度调制芯片204、所述时序控制芯片203、所述源驱动芯片201进行供电；所述脉冲宽度调制芯片204根据所述可编程伽玛校正缓冲芯片202进行脉冲宽度调节后的电源的电压产生多个控制电压；所述时序控制芯片203将所述视频信号转换为数字信号以及产生时钟信号；所述源驱动芯片201根据所述数字信号和所述控制电压产生数据信号，最终将数据信号输入到所述数据线上。所述驱动部还可具有栅驱动芯片（图中未示出），所述栅驱动芯片可根据所述时序控制芯片203的时钟信号产生扫描信号。
本实施例可将时序控制芯片203中的主体模块31也设置在柔性连接器22上，而将时序控制芯片203中的存储模块32设置在印刷电路板21上。所述时序控制芯片203包括主体模块31和存储模块32，所述存储模块32譬如为时序控制芯片203中用于存储程序的部份，所述主体模块31譬如为时序控制芯片203中的硬件部分。
由于所述存储模块是所述时序控制芯片的核心部分，因此将主体模块设置在柔性连接器上，而将存储模块保留在印刷电路板上，可以保证时序控制芯片工作效率，使其工作更加稳定。同时将其余的芯片都放置在柔性连接器上，不仅保证工作效率，且减小了印刷电路板尺寸，降低了印刷电路板的打样费用；且由于制作面板时，需要柔性连接器具有一定的尺寸，将其他芯片设置在柔性连接器上，并不会增大柔性连接器的尺寸，因此当印刷电路板尺寸减小时，相应地减小所述驱动部的空间，可进一步减小面板的尺寸。
请参照图5，图5为本发明第一种液晶显示面板中第二种驱动部的结构示意图；
本实施例和第一种驱动部的区别在于：
如图5所示，将整个所述时序控制芯片203设置在所述柔性连接器22上。
由于将整个时序控制芯片设置在柔性连接器上，从而进一步减小印刷电路板的尺寸，从而进一步减小面板的尺寸。
请参照图6，图6为本发明第二种液晶显示面板中第一种驱动部的结构示意图；
本发明第二种液晶显示面板，譬如为GOA驱动方式的液晶显示面板，其包括本体部和驱动部，所述本体部包括多条数据线和多条扫描线，以及由所述数据线和所述扫描线限定的多个像素单元；如图6所示，所述驱动部包括印刷电路板21和柔性连接器22；所述本体部通过所述柔性连接器22与所述印刷电路板21连接；所述驱动部具有多个芯片和电子元件；其中所述多个芯片包括源驱动芯片201、脉冲宽度调制芯片204、可编程伽玛校正缓冲芯片202以及时序控制芯片203以及电平转换芯片205；所述电平转换芯片205用于对所述时序控制芯片203的时钟信号的电压进行转换后，输入所述扫描线，对扫描线进行逐行驱动。
这种驱动方式的液晶显示面板的驱动部和普通驱动方式的液晶显示面板类似，也可以有2种设置方式。
结合图6和4，将所述源驱动芯片201、所述脉冲宽度调制芯片204、所述可编程伽玛校正缓冲芯片202、所述电平转换芯片205以及所述时序控制芯片203中的主体模块31设置在所述柔性连接器22上；而将时序控制芯片203中的存储模块32以及所述电子元件（电阻、电容、电感）设置在印刷电路板21上。
由于将电子元件设置在柔性连接器上，导致电子元件工作不稳定，尤其在柔性连接器上设置电感比较困难，因此将电子元件设置在印刷电路板上。
由于所述存储模块是所述时序控制芯片的核心部分，因此将主体模块设置在柔性连接器上，而将存储模块保留在印刷电路板上，可以保证时序控制芯片工作效率，使其工作更加稳定。同时将其余的芯片都放置在柔性连接器上，不仅保证工作效率，且减小了印刷电路板尺寸，降低了印刷电路板的打样费用；由于制作面板时，需要柔性连接器具有一定的尺寸，将其他芯片设置在柔性连接器上，并不会增大柔性连接器的尺寸，因此当印刷电路板尺寸减小时，相应地减小所述驱动部的空间，可进一步减小面板的尺寸。
如图7所示，将整个所述时序控制芯片203设置在所述柔性连接器22上。
由于将整个时序控制芯片设置在柔性连接器上，从而进一步减小印刷电路板的尺寸，从而进一步减小面板的尺寸。
