具体地，所述显示面板2设于所述荧光膜13远离所述数个MINI LED芯片12的一侧。
具体地，所述MINI LED基板11靠近和远离所述数个MINI LED芯片12的两面均设置有走线，所述MINI LED驱动IC14与所述数个MINI LED芯片12通过所述走线以形成电性连接。
具体地，所述MINI LED面光源1还包括设于所述荧光膜13和所述显示面板2之间的光学膜片组15。可选地，所述光学膜片组15包括增亮膜片与扩散膜片等，可以提高所述MINI LED面光源1的亮度和发光均匀性。
具体地，所述MINI LED基板11包括面光源显示区及位于所述面光源显示区外围的面光源非显示区，所述面光源非显示区包括与所述MINI LED驱动IC14电性连接的面光源接口111，所述面光源接口111通过连接器、焊接或热压与所述柔性电路板组件3电性连接，所述面光源接口111与所述柔性电路板组件3电性连接，所述MINI LED驱动IC14通过所述面光源接口111与所述柔性电路板组件3电性连接。
具体地，所述面光源接口111包括面光源电源接口及数据接口。
具体地，所述面光源接口111通过所述走线从而与所述MINI LED驱动IC14电性连接。
具体地，所述数个MINI LED芯片12呈阵列排布。
具体地，如图3所示，为本发明的液晶显示器的显示面板2的第一实施例的示意图，所述显示面板2为COG(Chip On Glass，即芯片搭载在玻璃基板上)显示面板，所述显示面板2包括显示区21及位于所述显示区21外围的非显示区22，所述非显示区22设有显示驱动IC23，所述显示驱动IC23用于对所述显示面板2进行显示驱动，所述显示驱动IC23与所述柔性电路板组件3电性连接。
具体地，如图4所示，为本发明的液晶显示器的显示面板2的第二实施例的示意图，所述显示面板2为COF(Chip On Film，即覆晶薄膜)显示面板，所述显示面板2包括显示区21及位于所述显示区21外围的非显示区22，所述非显示区22具有覆晶薄膜4，所述覆晶薄膜4具有显示驱动IC23，所述显示驱动IC23用于对所述显示面板2进行显示驱动。由于所述显示驱动IC23设置在所述覆晶薄膜4上，因此所述显示面板2的非显示区22较小，故能够实现显示面板2的超窄边框设计，使得液晶显示器达到超窄边 框设计的目的。进一步地，所述显示驱动IC23通过所述非显示区22的覆晶薄膜4与所述柔性电路板组件3电性连接。
具体地，如图5所示，所述MINI LED驱动IC14通过所述柔性电路板组件3与所述显示驱动IC23电性连接以接收显示驱动IC23的信号。进一步地，所述显示驱动IC23具有MINI LED面光源的驱动算法，所述MINI LED面光源的驱动算法根据显示画面计算出一组背光系数，通过所述数据接口将背光系数传输到所述MINI LED驱动IC14，从而控制数个MINI LED芯片12的亮度。
具体地，如图6所示，所述显示面板2具有电路主板IC，所述MINI LED驱动IC14通过所述柔性电路板组件3与所述电路主板IC电性连接以接收所述电路主板IC的信号。所述电路主板IC具有MINI LED面光源的驱动算法，所述MINI LED面光源的驱动算法根据显示画面计算出一组背光系数，通过所述数据接口将背光系数传输到所述MINI LED驱动IC14，从而控制数个MINI LED芯片12的亮度。优选地，所述面光源接口111通过连接器与所述柔性电路板组件3电性连接。
综上所述，本发明的液晶显示器包括MINI LED基板、设于所述MINI LED基板一侧面的数个MINI LED芯片、设于所述MINI LED基板另一侧面的MINI LED驱动IC以及覆盖所述数个MINI LED芯片的荧光膜，所述MINI LED驱动IC驱动所述数个MINI LED芯片发光，相比于现有技术来说，不需要将MINI LED驱动IC设置在柔性电路板组件上，节省了一个连接器，避免压缩柔性电路板组件的设计空间，同时有效减小MINI LED驱动IC与所述数个MINI LED芯片电性连接的走线难度，降低了制作成本。
以上所述，对于本领域的普通技术人员来说，可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形都应属于本发明权利要求的保护范围。
