• For saving driver ics ' power consumption and cost , this research proposes a novel display pixel design with integrated charge pump circuits . the proposed display pixel design can supply driving voltage more than double the input voltage to display pixels . there are two advantages for this developed novel pixel design . first , the power consumption of the panels with the proposed novel pixels can be reduced due to the lower voltage on data lines . second , the high voltage driver ics are not necessary , such that the cost and power consumption of the corresponding driving systems can be diminished . from the simulation results , the pixel voltage indeed could raise to more than double input voltage by this proposed design . in addition , the pixels with charge pump circuits also retrench about half power consumption than the conventional display pixels
  为了节省面板电路驱动芯片的功率损耗以及制作成本,本研究提出一种新的像素电路设计,而在设计中将会融合电荷泵电路.利用这种电路设计的像素可有效地将像素电极上的驱动电压提高到输入电压的2 3倍以上.此像素电路设计具有两个优势:第一,可以有效降低显示面板的像素功率损耗;第二,不需高电压的面板电路驱动芯片,因此可节省芯片的成本及功率损耗.由模拟结果可知,像素电极上的驱动电压确实可由此像素电路设计而提高到输入电压的2 3倍以上;而像素的功率损耗也可有效地降低,约为传统像素的1 / 2
