一种低功耗的显示面板，包括彩膜基板、TFT基板、液晶层、上偏光片和下偏光片。
所述彩膜基板和TFT基板相对设置，所述液晶层位于彩膜基板与TFT基板之间，彩膜基板与TFT基板通过围绕其周边的封框胶将液晶层密封在由彩膜基板与TFT基板形成的盒体内，并通过设置在彩膜基板与TFT基板之间的多个间隔物保持该盒体厚度的稳定性。
所述彩膜基板包括第一玻璃基板及位于所述第一玻璃基板上且远离所述阵列基板方向的彩色滤光片。当然，对于MONO，也可以不设置彩色滤光片。
所述TFT基板包括第二玻璃基板，以及位于所述第二玻璃基板上且朝向所述彩膜基板方向的功能层，所述功能层中包括TFT器件。
所述TFT基板上还设有像素驱动电路，所述像素驱动电路采用低功耗的电路结构，所述像素驱动电路包括两个或以上串联的晶体管，所述显示面板的模式为全透射型；优选地，参阅图1，所述像素驱动电路包括两个串联的晶体管，具体地，所述像素驱动电路包括第一Gate线（GL1）、第二Gate线（GL2）、Source线（SL）、第一晶体管（M1）、第二晶体管（M2）和像素电极，其中，
所述第一晶体管，其具有连接第一Gate线的栅极、连接像素电极的漏极、以及连接所述第二晶体管的漏极的源极；
所述第二晶体管，其具有连接第二Gate线的栅极、连接Source线的源极。
本发明像素驱动电路的工作原理如下：当第一Gate线和第二Gate线同时为0，即同时处于断开状态，则关闭该像素，第一晶体管M1和第二晶体管M2帮助电容储存信息；当第一Gate线为0，第二Gate线为1时，则关闭该像素；当第一Gate线和第二Gate线同时为1时，可写入高电平或低电平，实现写入功能；当第一Gate线为1，第二Gate线为0时，则关闭该像素。
而且，第一晶体管和第二晶体管的类型可以相同，也可以不同，只需根据自身阈值电压的特点调整相应的时序高低电平即可。优选地，所述第一晶体管和第二晶体管均为薄膜晶体管。
更优选地，参阅图2，所述像素驱动电路包括三个串联的晶体管，具体地，所述像素驱动电路包括：第一Gate线（GL1）、第二Gate线（GL2）、Source线（SL）、第一晶体管（M1）、第二晶体管（M2）、第三晶体管（M3）和像素电极，其中，
所述第一晶体管，其具有连接第一Gate线的栅极、连接像素电极的漏极、以及连接所述第二晶体管的漏极的源极；
所述第二晶体管，其具有连接第二Gate线的栅极、连接所述第三晶体管的漏极的的源极；
所述第三晶体管，其具有连接第二Gate线的栅极、连接Source线的源极。
在本实施例中，其中，第一Gate线、第二Gate线和Source线例如可选用金属材料，但本发明不限于此，也可以为合金、金属材料的氮化物、金属材料的氧化物、金属材料的氮氧化物、或是金属材料与其它导电材料的堆叠层。
本发明中，像素驱动电路采用上述电路结构，可以实现超低功耗，并且可以支持低帧刷新。
所述上偏光片位于所述彩膜基板远离所述TFT基板的一侧，所述下偏光片设置于所述TFT基板远离所述彩膜基板的一侧，所述下偏光片为反射式偏光片。本发明中，显示面板中的下偏光片选择反射式偏光片，对光源进行充分利用，可以降低功耗，增加画面品质效果。
所述显示面板为透射型液晶显示面板，所述显示面板采用高透过率材料制成。
显示面板表面的光线可以透过TFT基板进入下偏光片，同时下偏光片为反射式偏光片可以反射透过显示面板的入射光线，从而增加透过显示面板的光通量。
本发明中，所述TFT基板可以不包括黑色矩阵，通过上述设置，可以增加透过显示面板的光通量，从而提高反射率。
本发明中，所述TFT基板上还可以设置有黑色矩阵，所述黑色矩阵仅遮挡TFT基板上的TFT器件所在的区域和/或TFT走线的区域。通过上述设置，可以减少显示面板对盒精度的要求，同时对TFT器件起到了遮光作用，保护TFT器件免受近紫外光和/或紫外光的影响，使得TFT器件的性能稳定，提升了该显示面板的使用寿命，使得黑色矩阵在实现自身作用的同时尽量减少黑色矩阵的面积，增加透过显示面板的光通量，增加反射率，提高亮度。
 本发明的另一实施例提供一种低功耗的显示模组，包括上述显示面板，以及向所述显示面板提供光源的照明单元。
其中，所述照明单元可以是前景光，也可以是外部光。
传统的显示模组一般为前LCD、后背光源的结构，本发明改变传统的背光方式，去掉现有背光源，而将光源移至显示面板上方，采用前景光或外部光的方式，利用显示面板较高的反射率，使得仅需要一点点光源照亮就能满足其在黑暗环境下使用，且并不需要足够的亮度，因此也能节省背光带来的大量功耗。
其中，所述前景光可采用现有技术实现，容易根据实际需要进行选择，此于本领域技术人员来说为常规手段，在此不再赘述。例如，所述前景光包括设置于所述显示面板出光面上的一个导光板，在导光板的侧面设置发光组件，发光组件发出的一部分光线经过导光板上的导光网点反射进后方的显示面板，再经过显示面板反射出来，从而显示内容。
以上所述实施例仅表达了本发明的实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制，但凡采用等同替换或等效变换的形式所获得的技术方案，均应落在本发明的保护范围之内。
