Light-emitting control circuit, light-emitting control method and shift register

Abstract

A light-emitting control circuit, a light-emitting control method and a shift register. The light-emitting control circuit comprises an inputting terminal (Input), an input sampling unit (), an outputting unit (), a resetting unit (), an output pulling-down unit () and an outputting terminal for a light-emitting control signal (EM[n]). The input sampling unit () samples an input signal under a control of a first clock signal (CK); the outputting unit () generates a light-emitting control signal under a control of a second clock signal (CK) after the input sampling unit () samples the input signal; the resetting unit () resets the light-emitting control signal through the output pulling-down unit () under a control of a third clock signal (). An OLED device is in an OFF state during a process for writing display data into pixel cells and the OLED device is turned on to emit light after the display data is written into the pixel cells, thus a display image is guaranteed not to generate flickers due to an unstable state of a pixel circuit as the data is written.
