    • A voltage level shifter formed by single-typed transistors comprises two input terminals, two power supply terminals, a plurality of thin-film transistors, and an output terminal. Another voltage level shifter formed by single-typed transistors comprises two input terminals, an output terminal, two power supply terminals, two input units, a first thin-film transistor, a disable unit, a feedback unit, and a second thin-film transistor. The voltage level shifters are formed by single-typed TFTs. When integrating the voltage level shifters into a substrate of a TFT display, the manufacturing processes are simplified. Besides, power is saved.

    • A single clock driven shift register comprising multiple stages is provided. The (M)th stage comprises a latch unit, a logic unit, and a non-overlap buffer. The latch unit latches an input signal from the (M−1)th stage according to a clock signal. The logic unit connecting to an output terminal of the latch unit deals with an output signal of the latch unit and the clock signal with an NAND logic calculation. The non-overlap buffer connecting to the output terminal of the logic unit comprises at least three inverters connected in a serial, and an output signal of the first inverter coupled to the output terminal of the logic unit is input to an latch unit of the (M+1)th stage. Meanwhile, an output signal of the non-overlap buffer of the (M−1)th stage is input to the non-overlap buffer or the logic unit to delay the output signal of the non-overlap buffer.
    • 提供包括多级的单个时钟驱动移位寄存器。 第(M)级包括锁存单元,逻辑单元和非重叠缓冲器。 锁存单元根据时钟信号锁存来自第(M-1)级的输入信号。 连接到锁存单元的输出端的逻辑单元用NAND逻辑计算处理锁存单元的输出信号和时钟信号。 连接到逻辑单元的输出端子的非重叠缓冲器包括串联连接的至少三个反相器,并且耦合到逻辑单元的输出端的第一反相器的输出信号被输入到 M + 1)级。 同时,将第(M-1)级的非重叠缓冲器的输出信号输入到非重叠缓冲器或逻辑单元,以延迟非重叠缓冲器的输出信号。
