发光二极管象素阴阳电路及三态驱动法一种发光二极管象素阴阳电路及三态驱动法,其特征是在多于二根公共引线的电路中至少有一根引线既接有至少一个发光二极管象素的阳极,又接有至少一个发光二极管象素的阴极。而与象素电路所有引线相连的驱动电路的端口采用三态口,以高阻态、高电平、低电平三种状态,共同参与分时段地对各象素进行有序的点亮或熄灭,实现动态扫描显示。本发明可以大大提高发光二极管象素电路的象素引脚比,从而降低显示系统的
LED pixel yin and yang circuit and three-state driving method LED pixel yin and yang circuit and three-state driving method, and is characterized in that at least one lead in the circuit of more than two common leads is connected with at least one LED The anode of the element is in turn connected to the cathode of at least one of the light-emitting diode pixels. While the driving circuit port connected with all the leads of the pixel circuit adopts a tri-state port, and takes three states of a high resistance state, a high level and a low level to participate in an orderly lighting of each pixel in time division or Off, to achieve dynamic scanning display. The invention can greatly improve the pixel-to-pixel ratio of the pixel circuit of the light-emitting diode so as to reduce the
