Abstract

The invention discloses an area array electronically-controlled liquid crystal light-diverging micro-cylinder chip based on dual voltage signal drive control, comprising a liquid crystal light-diverging micro-cylinder array, a first drive control signal input port and a second drive control signal input port. The liquid crystal light-diverging micro-cylinder array includes m*n elements, with both m and n being integers greater than 1. The liquid crystal light-diverging micro-cylinder array is in a liquid crystal sandwich layer; a first substrate, a top area electrode plate, an inter-electrode insulating layer, a top patterned electrode plate, a first liquid crystal orientation layer, a liquid crystal layer, a second liquid crystal orientation layer, a meshed common ground electrode plate and a second substrate are disposed in order between an upper layer and a lower layer; the top area electrode plate and the meshed common ground electrode plate are made on the first substrate and the second substrate respectively; the top patterned electrode plate is made by arranging m*n micro rectangular pores in order; the meshed common ground electrode plate is made by evenly arranging multiple pores. The area array electronically-controlled liquid crystal light-diverging micro-cylinder chip is compact in structure, allows efficient divergent projection of beams and fine modulation and is flexible to control and well environment adaptive.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic display, and more specifically relates to an area-array electronically controlled liquid crystal light-diverging micro-cylindrical mirror chip driven and controlled by dual-channel voltage signals. Background technique [0002] The so-called stereoscopic or three-dimensional vision is a stereoscopic perception produced by distinguishing the distance of objects based on the binocular parallax of people. By separating the plane images seen by the left and right eyes, the observer can observe the image or video information with a sense of spatial depth through the two-dimensional display plane, creating a feeling of being on the scene. So far, a variety of stereoscopic display technologies based on planar image projection and differential synthesis have been developed, such as typical polarized glasses, parallax barrier stereoscopic display, pointing at the light source Time-series composite 3D...

Problems solved by technology

[0003] Although the electronically controlled liquid crystal micro-lens array has shown some advantages in the development of two-dimensional and three-dimensional general display technology, there are still some obvious deficiencies and defects that restrict the further development, mainly in the following aspects: The cylindrical lens performs further regional segmentation and directional projection on the planar local image covered by the cylinder to form a sequence of sub-images with common overlapping, and in the process of obtaining a three-dimensional image through binocular observation and synthesis, as the unit micro of the sub-aperture The structural size of the cylindrical lens is used as the basic display pixel size, which determines the space of the constructed 3D image. resolution Or clarity, at present because of its surface size of the micro-cylindrical lens is still large and seriously insufficient; (2) The beam delivery performance of the liquid crystal micro-cylindrical mirror is determined by the conventional voltage signal applied to the control electrode of the micro-cylindrical mirror, which is still lacking. The fine control ability of the spatial distribution of the aspheric refractive index of the micro-cylindrical lens is reflected in the fact that the beam projection and aberration of the sub-aperture cannot be finely compensated and corrected; (3) At present, the spatial distribution of the refractive index is mostly used The converging mode liquid crystal micro-cylindrical lens has a relatively narrow field of view for image projection or display, and the image distortion becomes more and more obvious as the viewing angle increases.

The above defects limit the effective use of arrayed electronically controlled liquid crystal micro-lenticules and its technical advantages in stereoscopic display applications.
