Embodiment Construction

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0033] Holographic display technology uses the principle of light interference and diffraction to perform optical holography, specifically, such as figure 1 As shown, the light emitted by the laser 21 is divided into two beams, one beam of light irradiates the object 22, and the reflected light and scattered light on the surface of the object 22 reach the holographic dry plate 23 and form an object light wave A. Another beam of light cohe...

Abstract

Embodiments of the present invention provide an addressing method of a spatial light modulator, a holographic display device and a control method thereof, which relate to the field of display technology and can simplify the addressing process of a spatial light modulator. The addressing method of the spatial light modulator includes: firstly, dividing the spatial light modulator to obtain multiple modulation areas, each modulation area includes M loading sub-areas, and each loading sub-area includes at least one pixel unit. Where M≥2, M is a positive integer. Then, within one frame, a loading sub-area of ​​each modulation area is addressed, so as to load the holographic data of one frame of hologram to each pixel unit of the loading sub-area.

Description

Technical field [0001] The invention relates to the field of display technology, and in particular to an addressing method of a spatial light modulator, a holographic display device and a control method thereof. Background technique [0002] With the increasing popularity and use of 3D (Dimension) display technology, holographic display technology has gradually entered people's lives and work. The holographic display technology is different from the parallax stereo display technology. It has many advantages such as large depth of field and no vertigo. [0003] However, with the continuous improvement of resolution, the amount of data calculation in the holographic display process also increases, and the image loading time is long, so that the holographic display device has a lower refresh rate of the screen during dynamic holographic display, which reduces the display effect . Summary of the invention [0004] The embodiments of the present invention provide an addressing method o...
