摘要： A shift register circuit includes a first pull-down control sub-circuit and a first noise reduction sub-circuit. The first pull-down control sub-circuit includes a first transistor and a second transistor, and a ratio of a width-to-length ratio of a channel of the second transistor to a width-to-length ratio of a channel of the first transistor is greater than 5:1. The first pull-down control sub-circuit transmits, in response to a first voltage signal received at a first voltage signal terminal, the first voltage signal to a first pull-down node through the first transistor, and transmits a second voltage signal received at a second voltage signal terminal to the first pull-down node through the second transistor under control of a voltage of a pull-up node. The first noise reduction sub-circuit transmits the second voltage signal to the pull-up node under control of a voltage of the first pull-down node.

摘要： The present application describes a display panel having an array substrate; a counter substrate facing the army substrate; and a light guide grating layer on a side of the array substrate distal to the counter substrate. The light guide grating layer in a three-dimensional image display mode is configured to have a plurality of light emitting regions and a plurality of light non-emitting regions alternately arranged, thereby forming a grating. The light guide grating layer is configured to emit light from the plurality of light emitting regions, and configured not to emit light form the plurality of light non-emitting regions, thereby displaying a three-dimensional image in the display panel.
