Abstract

The invention relates to an amplitude modulation method and device for a time domain modulation type liquid crystal microdisplay.The method comprises the steps of acquiring the number of pixels of the liquid crystal microdisplay N[total]*M[total], and dividing the liquid crystal microdisplay into multiple sub-regions, wherein the number of pixels of each sub-region is N*M; acquiring the pixel gray value V[i] (V[i]<[0,1]), needing to be modulated, of each sub-region; selecting V[i]*N*M pixels randomly from the sub-region i, and setting the V[i]*N*M pixels to be maximum binary system time domain sequence codes; setting the other (1-V[i])*N*M pixels to be minimum binary system time domain sequence codes.The device is realized based on the amplitude modulation method.The advantages of high refresh rate and high resolution of the time domain modulation type liquid crystal microdisplay are reserved, both amplitude modulation under the time integral effect and amplitude modulation under the space integral effect can be achieved, and coherence between different pixels in the spatial domain can be achieved based on a time domain type spatial light modulator.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an amplitude modulation method and device for a time-domain modulation liquid crystal microdisplay. Background technique [0002] With the development of display technology, research on large-screen optical information display systems has become an irreversible trend in contemporary society, and spatial light modulators are key devices for optical information processing. Spatial light modulators are mainly used in imaging, projection, phase modulation, holographic projection, etc., and are key devices in modern optical fields such as real-time optical signal processing, adaptive optics, and optical computing. To a large extent, the performance of microdisplays, that is, the spatial light modulators in them, determines the practical value and development prospects of these fields. [0003] According to different modulation parameters, spatial light modulators can be divided into...
