Abstract

The invention provides a directive color filter and a naked eye 3D display device. The directive color filter comprises a color filter and a directive functional structure layer. The color filter comprises a plurality of filtering units, and each filtering unit comprises at least three filtering subunits in different colors. The directive functional structure layer comprises a plurality of structure units, and each structure unit is arranged corresponding to one filtering unit. Each structure unit comprises at least three structure subunits. Each structure subunit is arranged corresponding to one filtering subunit. Each structure subunit comprises a plurality of nano diffraction gratings. The period and angles of orientation of the nano diffraction gratings in the same structure subunit are different, so that light in two colors would not be emitted by the same nano diffraction grating, and a light crosstalk problem would not occur. The directive color filter is easy to realize technically, so the multi-view naked eye 3D display device without visual fatigue based on a directive backlight technology can easily have practical applications.

Description

technical field [0001] The invention relates to the technical field of stereoscopic display, and more specifically, relates to a directional color filter and a naked-eye 3D display device. Background technique [0002] Because the 3D display technology can make the picture more three-dimensional and realistic, so that the audience has an immersive feeling, therefore, the 3D display technology is more and more popular among people. [0003] The principle of 3D display technology is to use people's left and right eyes to receive different images with parallax respectively, and then superimpose the parallax images through the brain to form an image with stereoscopic effects such as front and rear, left and right, up and down, and far and near. Although naked-eye 3D display devices based on the principle of parallax continue to be produced in the prior art, the existing naked-eye 3D display devices have problems such as image crosstalk that easily causes visual fatigue and small...
