Abstract

The invention provides a shifting register and a gate drive circuit using the shifting register. The shifting register comprises a plurality of repeat units, wherein each repeat unit comprises at least five grades of shifting register units, the last grade of shifting register units is structurally different from the preceding grades of shifting register units, the preceding grades of shifting register units are structurally the same and all comprise four switch units, and the last grade of shifting register units has a reset function and comprises five switch units. The shifting register is stable in outputting, simple in structure, and low in power consumption, so that the gate drive circuit using the shifting register is small in size.

Description

Technical field [0001] The present invention relates to a shift register, in particular to a shift register suitable for a display device and a gate driving circuit using the shift register. Background technique [0002] Flat-panel display devices such as liquid crystal displays, LED displays with excitation light, etc., have many advantages such as thinness, energy saving, and no radiation, so they are widely used in high-definition digital TVs, computers, personal digital assistants (PDAs), mobile phones, digital cameras, etc. In electronic equipment. [0003] A flat display device usually includes a pixel circuit and a driving circuit. The pixel circuit includes a plurality of gate lines and a plurality of data lines, and a plurality of pixel units formed by crossing the gate lines and the data lines. The driving circuit mainly includes a gate driving circuit. And source drive circuit. The gate driving circuit usually has a shift register, and the shift register has a pluralit...
