A 3D display device and a 3D terminal for realizing floating touch, a computer readable storage medium, a computer program product and a 3D display system are also provided.

A display assembly monitors movements in a waveguide assembly and corrects for aberrations in image light caused by the monitored movements. For example, an artificial reality headset may include a display assembly that monitors for changes in shape or displacement of waveguide assemblies that generate three dimensional images for display with a real world environment. The display assembly includes movement sensors (e.g., piezoelectric movement sensors) coupled to the waveguide assembly. The movement sensors monitor the movement of the waveguide assembly and provide the monitored movement to a display controller that generates instructions for correcting aberrations in the image light.

Methods, systems and apparatuses may provide for technology that generates a seed value, wherein the seed value is dedicated to a position of an input pixel, generates a dithered pixel value based on the seed value and a value of the input pixel, and conducts a scan-out of the dithered pixel value to a display panel. In one example, the technology generates an intermediate value based on the seed value and one or more fixed constants and generates a pseudo random number based on the intermediate value and a programmable constant, wherein the dithered pixel value is generated based on the pseudo random number and the value of the input pixel.
