    • 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.
    • 发光控制电路,发光控制方法和移位寄存器。 发光控制电路包括输入端子(Input),输入采样单元(11),输出单元(12),复位单元(13),输出下拉单元(14)和输出端子 发光控制信号(EM [n])。 输入采样单元(11)在第一时钟信号(CK1)的控制下采样输入信号; 输出单元(12)在输入采样单元(11)对输入信号进行采样之后,在第二时钟信号(CK2)的控制下产生发光控制信号; 复位单元(13)在第三时钟信号(13)的控制下通过输出拉出单元(14)复位发光控制信号。 在将显示数据写入像素单元的过程中,OLED器件处于截止状态,并且在将显示数据写入像素单元之后,OLED器件导通以发光,从而保证显示图像不会产生闪烁 到数据写入时的像素电路的不稳定状态。
