Example Embodiment
[0118] Example 1: Combination Figure 8a The shift register shown and Figure 8b Shown Figure 8a The input and output timing diagram of, describes the working process of the shift register provided by the embodiment of the present invention. Specifically, select such as Figure 8b There are four stages from A to D in the input and output timing diagram shown. In the following description, 1 represents a high-level signal, and 0 represents a low-level signal.
[0119] In phase A, Input=0, CLKB=0, CLK=1, Reset=1, and Ref1=1. Because Reset=1, the ninth switch transistor T9 is turned off; because Input=0, the eighth switch transistor T8 is turned on, and Ref1 is turned on with the second node P2, so that the second node P2 is at a high level, and the tenth The switching transistor T10 and the sixth switching transistor T6 are turned off, and the closed sixth switching transistor T6 turns off the first switching transistor T1; at the same time, since CLKB=0, the seventh switching tr...
Example Embodiment
[0124] Embodiment 2: Combination Figure 9a The shift register shown and Figure 9b Shown Figure 9a The input and output timing diagram of, describes the working process of the shift register provided by the embodiment of the present invention. Specifically, select such as Figure 9b There are four stages from A to D in the input and output timing diagram shown. In the following description, 1 represents a high-level signal, and 0 represents a low-level signal.
[0125] In phase A, Input=1, CLKB=1, CLK=0, Reset=0, Ref1=0. Because Reset=0, the ninth switching transistor T9 is turned off; because Input=1, the eighth switching transistor T8 is turned on, and Ref1 is turned on with the second node P2, so that the second node P2 is at a low level, thereby making the tenth The switching transistor T10 and the sixth switching transistor T6 are turned off, and the closed sixth switching transistor T6 turns off the first switching transistor T1; at the same time, since CLKB=1, the seven...
