Embodiment Construction

[0025] Please refer to Figure 4 , Is the structure diagram of the scan driver of the present invention. The scan driver includes a first shift register 10, which is used to scan the scan lines according to the first scan mode by the first clock signal CPV1 and the first start pulse signal DIO1 from the controller 70;

[0026] The second shift register 20 is configured to receive the second clock signal CPV2 and the second start pulse signal DIO2 from the controller 70 to scan the scanning lines according to the second scanning mode;

[0027] The selection unit 30 is connected to the first shift register 10 and the second shift register 20, and is configured to receive a selection signal SR_SEL from the controller 70 to select the first shift register 10 according to the first type of scanning Scan the scan line in a mode or select the second shift register 20 to scan the scan line in the second scan mode;

[0028] The logic control unit 40, connected to the selection unit 30, is co...

Abstract

The invention discloses a scanning driver and a driving method. The scan driver includes first and second shift registers, which receive first and second clock signals and first and second start pulse signals to scan the scan lines according to the first or second scan mode; the selection unit receives The selection signal is used to select the first or second shift register to scan; the logic control unit receives the output enable signal to control the output; the level conversion unit outputs the level signal; the output amplification unit amplifies the level signal and outputs it to the scanning row, so as to This implementation scan driver satisfies the requirements of progressive scan and out-of-order scan.

Description

Technical field [0001] The invention relates to the field of display technology, in particular to a scan driver and a driving method of the scan driver. Background technique [0002] Existing scan drive (e.g. figure 1 (Shown) based on the shift register can only be driven by progressive scan (such as figure 2 and image 3 (Shown) scan scan lines. In some circuits with special functional requirements, a scan driver is required to scan scan lines out of order, so the existing scan driver cannot meet the requirements. Summary of the invention [0003] The main technical problem solved by the present invention is to provide a scan driver and a driving method of the scan driver to meet the requirements of progressive scanning and disordered scanning. [0004] In order to solve the above technical problems, a technical solution adopted by the present invention is to provide a scan driver, including: [0005] The first shift register is configured to receive the first clock signal and the ...
