A pixel compensation circuit and a display

The present invention discloses a method and a display pixel compensation circuit for compensating the threshold value of the NMOS driving transistor pixel drift. The pixel compensation circuit comprises: a first switching unit, a second switching unit, a third switching unit fourth switching unit, a fifth switch means, sixth switch means, the light emitting device and a capacitor; wherein the first switching unit, the first second switching means, a third switching unit fourth switching unit, a fifth switch means, sixth switch means comprises three connections. Pixel compensation circuit of the present invention to provide a low process requirements, and less of the input signal can greatly simplify the design of plates, increasing the number of pixels of the display have per inch, can be accurately related to the output current signal into the screen, thereby improving the actual display screen color uniformity to ensure not displayed correctly.
