Abstract: Disclosed is a shift register unit, a gate driving circuit and a driving method, as well as a display apparatus. The shift register unit has a working cycle including an input phase, an output phase, a reset phase and a maintaining phase. In the reset phase, a clock signal is transmitted to an output terminal to pull a voltage of the output terminal down to a reference voltage, and the pulled-down voltage of the output terminal is subsequently changed from the reference voltage to a gate-off voltage. In the maintaining phase, the voltage of the output terminal is maintained at the gate-off voltage. The reference voltage is smaller than the gate-off voltage.

Abstract: This disclosure provides a light source assembly and a display device, and the light source assembly includes: a first substrate and a second substrate arranged opposite to each other; a waveguide layer arranged between the first substrate and the second substrate; and a side-incident collimated light source arranged on a side of the waveguide layer, wherein the refractive index of the waveguide layer is higher than the refractive index of the first substrate, and the refractive index of the second substrate respectively; and light of the side-incident collimated light source is incident onto the side of the waveguide layer at a preset angle, and the incident light is totally reflected at the interference between the first substrate and the waveguide layer. In the embodiments of this disclosure, the light of the side-incident collimated light source is reflected totally at the interface between the waveguide layer and the first substrate under the principle of total reflection, and refracted at the interface between the waveguide layer and the second substrate, that is, the light is radiated from the surface of the second substrate, thus improving the efficiency of the light exiting from the single side of the light source assembly.
