Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] An aspect of the embodiments of the present invention provides a driving circuit, the driving circuit includes at least one virtual stage shift register and a shift register group electrically connected to the virtual stage shift register in a cascaded manner, wherein the shift The bit register group includes a first-stage shift register to an N-th stage shift register, and the N shift registers are also electrically connected in a cascaded...

Abstract

The invention provides a driving circuit, an array substrate and a display device, wherein the driving circuit comprises at least one stage of virtual-stage shift register; and a shift register set which is electrically connected with the virtual-stage shift register in a cascading manner, wherein the shift register set comprises a first-stage shift register, a second-stage shift register, ..., an N-stage shift register. Furthermore the occupation area of the virtual-stage shift register is smaller than that of an i-th shift register, wherein N is an integer which is not less than 2 and i is a positive integer which is not larger than N. Because the occupation area of the virtual-stage shift register is smaller than that of the i-th shift register, the frame area of the display device can be relatively reduced and a requirement for narrow frame of the display device is satisfied.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a driving circuit, an array substrate and a display device. Background technique [0002] An existing display device includes a display area and a frame area around the display area. In the display device, the driving chip provides driving signals to the pixel units in the display area through the driving circuit integrated in the frame area, so as to control the pixel units to display images. [0003] In the prior art, in order to provide a reset signal to the shift register in the drive circuit to avoid the output of an error signal, a virtual stage shift register is usually added to the drive circuit. The virtual stage shift register is located in multiple cascaded One or both ends of the shift register to provide a reset signal to the shift register. However, since the introduction of the virtual stage shift register will lead to a wider frame of the displ...
