Problems solved by technology

When the viewer exceeds the specific viewing area, as shown by the dotted line in the figure, one eye of the viewer can see the right-eye pixel 41 and the left-eye pixel 42 at the same time, resulting in a decrease in the three-dimensional effect and even blurring the image

Abstract

The invention provides an autostereoscopic display device comprising an image display unit, a parallax barrier, an image sensor and a processor. The image display unit displays right-eye pixels and left-eye pixels arranged alternatively, and the parallax barrier comprises light-proof shielding portions and light-transmitting slit portions arranged alternatively. The image sensor is used for sensing an image in front of the autostereoscopic display device. The processor comprises a face recognition module and a parallax barrier adjustment module, the face recognition module is used for judging the position of the face in the image, and the parallax barrier adjustment module is used for adjusting distribution positions of the light-proof shielding portions and the light-transmitting slit portions according to the position of the face so as to enable the right eye to be only capable of seeing the right-eye pixels and the left eye to be only capable of seeing the right-eye pixels.

Description

technical field [0001] The invention relates to a naked-eye stereoscopic display device. Background technique [0002] The naked-eye stereoscopic display device in the prior art utilizes the parallax of the two eyes to generate a three-dimensional effect. Among them, the use of Micro Parallax Barrier Array technology to achieve parallax three-dimensional effect (parallax stereogram) is to use the shading effect of parallel gratings to restrict the left and right eyes to see the left and right images respectively, so that the right eye can only see the image in the image. The right eye pixels, the left eye only sees the left eye pixels in the image, resulting in a difference in the images seen by the two eyes and a sense of stereoscopic effect. [0003] Such as figure 1 As shown, the naked-eye stereoscopic display device 10 using micro-barrier array technology includes an image display unit 40 and a parallax barrier unit (parallax barrier) 50 . The image display unit 40 is...
