图2为本发明的液晶显示面板的优选实施例的驱动电路的结构示意图；
图3为本发明的液晶显示面板的优选实施例的驱动电路的可编程直流电流源的局部结构示意图。
 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1，图1为本发明的液晶显示面板的优选实施例的结构示意图。本优选实施例的液晶显示面板10包括驱动电路11、数据线12、扫描线13以及像素单元14。驱动电路11用于提供数据信号以及扫描信号，数据线12用于传输数据信号，扫描线13用于传输扫描信号，像素单元14用于在扫描信号的控制下使用数据信号进行图像显示。
请参照图2，图2为本发明的液晶显示面板的优选实施例的驱动电路的结构示意图。其中驱动电路11包括可编程直流电流源111以及消角电阻R1，该可编程直流电流源111用于使用不同的基准电压VCC输出相应的消角电流；消角电阻R1用于根据可编程直流电流源111输出的消角电流产生相应的消角电压V1，该消角电压V1用于对扫描线13的扫描信号进行消角处理，从而避免扫描信号的突变对数据信号的影响。可编程直流电流源111的芯片IC1在电阻R3至电阻R8以及电容C2至电容C4控制下生成消角电流，消角电流通过消角电阻R1时生成消角电压V1。这里可编程直流电流源111优选为恒流源。
该恒流源的结构可如图3所示，图3为本发明的液晶显示面板的优选实施例的驱动电路的可编程直流电流源的局部结构示意图。该恒流源包括第一三极管Q1、第二三极管Q2、第一负载电阻R31以及第二负载电阻R32。
第一三极管Q1的射极分别与第一负载电阻R31的一端和地连接，第一三极管Q1的集电极分别与第二负载电阻R32的一端和第二三极管Q2的基极连接，第一三极管Q1的基极分别与第一负载电阻R31的另一端和第二三极管Q2的射极连接，第二三极管Q2的集电极输出消角电流，第二负载电阻R32的另一端与基准电压VCC连接。其中第一三极管Q1和第二三极管Q2均为PNP三极管。当然这里也可采用其他的恒流源的结构。上述恒流源的结构可设置在芯片IC1的内部或外部。
本优选实施例的可编程直流电流源111输出的消角电流只与基准电压VCC、第一负载电阻R31和第二负载电阻R32相关，在第一负载电阻R31和第二负载电阻R32固定的情况下，消角电流只与基准电压VCC相关，因此驱动电路11使用不同的基准电压VCC可产生不同的消角电压。
本发明的液晶显示面板10使用时，驱动电路11可根据液晶显示面板10的显示模式，确定数据信号、扫描信号以及消角电压。如液晶显示面板10处于3D显示模式，即液晶显示面板10需要同时显示多个画面，则驱动电路11可根据不同画面的数据信号确定不同的消角电压V1，即确定不同的可编程直流电流源111的基准电压VCC。这样驱动电路11可给不同的扫描线13提供不同的消角电压V1，以便对不同画面的扫描信号进行最佳的消角处理，避免了扫描信号的突变对数据信号的影响。由于消角电压V1只与基准电压VCC相关，驱动电路11只需调整可编程直流电流源111中的基准电压VCC即可方便的对扫描信号进行最佳的消角处理，整个消角处理过程快捷且成本低。
因此本优选实施例的液晶显示面板通过可编程直流电流源的设置可同时输出多个不同的消角电压，且3D显示效果较佳。
本发明还提供一种液晶显示装置。该液晶显示装置包括液晶显示面板以及背光源，该液晶显示面板包括驱动电路、数据线、扫描线以及像素单元。驱动电路用于提供数据信号以及扫描信号；数据线用于传输数据信号；扫描线用于传输扫描信号；像素单元用于在扫描信号的控制下使用数据信号进行图像显示。驱动电路包括可编程直流电流源以及消角电阻，可编程直流电流源用于使用不同的基准电压输出相应的消角电流，消角电阻用于根据消角电流产生相应的消角电压，其中消角电压用于对扫描信号进行消角处理。
优选的，该可编程直流电流源为恒流源。
优选的，该恒流源包括第一三极管、第二三极管、第一负载电阻以及第二负载电阻。
第一三极管的射极分别与第一负载电的一端和地连接，第一三极管的集电极分别与第二负载电阻的一端和第二三极管的基极连接，第一三极管的基极分别与第一负载电阻的另一端和第二三极管的射极连接，第二三极管的集电极输出消角电流，第二负载电阻的另一端与基准电压连接。其中第一三极管和第二三极管均为PNP三极管。
优选的，驱动电路对不同的画面信号使用不同的基准电压，以产生不同的消角电压。
本优选实施例的液晶显示装置的具体工作原理与上述的液晶显示面板的优选实施例中的描述相同或相似，具体请参见上述液晶显示面板的优选实施例中的相关描述。
本发明的液晶显示面板及液晶显示装置通过可编程直流电流源的设置可同时输出多个不同的消角电压，且3D显示效果较佳；解决了现有的液晶显示面板及液晶显示装置的驱动电路无法同时输出多个不同的消角电压，从而导致3D显示效果较差的技术问题。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
