US 2026/0113419 A1 · DISPLAY WITH INCREASED PIXEL COUNT

Abstract

Example methods, systems and devices provide a display with a higher resolution than the native resolution of a light modulator used. Optical components direct first light on first light paths from a light source to a light modulator and direct second light on second light paths from the light source to the light modulator. Each of multiple controllable elements of the light modulator modulates the first light to produce first modulated light to exit the light modulator at a first angle, and modulates the second light to produce second modulated light to exit the light modulator at a second, different, angle. Another set of optical components focus the first and second modulated light on a target to display first and second sequences of image frames, respectively, in which corresponding pixels in corresponding image frames are shifted by less than a pixel pitch relative to each other.

Dependent claims

A method comprising:

controlling a light source to alternately produce first light and second light multiple times in each image frame;
controlling one or more optical components to direct the first light to a light modulator at a first angle with respect to a surface of the light modulator;
controlling the one or more optical components to direct the second light to the light modulator at a second angle with respect to the surface of the light modulator, in which the second angle is different than the first angle;
modulating the first and second light, by the light modulator, to produce first and second modulations of light, in which corresponding pixels in corresponding image frames are offset by less than a pixel;
and
projecting the first and second modulations of light to create a perceived resolution exceeding a native resolution of the light modulator.
