Zusammenfassung: | 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 (11), an outputting unit (12), a resetting unit (13), an output pulling-down unit (14) and an outputting terminal for a light-emitting control signal (EM[n]). The input sampling unit (11) samples an input signal under a control of a first clock signal (CK1); the outputting unit (12) generates a light-emitting control signal under a control of a second clock signal (CK2) after the input sampling unit (11) samples the input signal; the resetting unit (13) resets the light-emitting control signal through the output pulling-down unit (14) under a control of a third clock signal (13). 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. |
