Description

Naked stereoscopic display

The present invention relates to an auto-stereoscopic display, and more particularly to an auto-stereoscopic display capable of guiding a viewer to find an optimal viewing position.

At present, the main principle of the naked-eye stereoscopic display is to enable the viewer's left and right eyes to simultaneously receive a parallax picture, and the viewer's brain can automatically merge the left-eye and right-eye images into a body image. The current naked-eye stereoscopic display mainly has two types of slit grating type and cylindrical lens type. When the viewer views the aforementioned naked-eye stereoscopic display, the stereoscopic effect can be seen only at a specific viewing angle, and the stereoscopic effect cannot be seen in the remaining viewing angles. Referring to FIG. 1, a schematic perspective view of a conventional naked-eye stereoscopic display 90 is shown. Each view period 9 of the naked eye stereoscopic display 90 includes a plurality of viewing angles 91-9N. When the viewer is at the intersection of adjacent two viewing angle periods 9 (i.e., adjacent viewing angles 9N, 91), the viewer cannot see the stereoscopic effect. The inventor of the present invention, if able to develop a new naked-view stereoscopic display, can generate a prompt message when the viewer is in a view where the stereoscopic effect cannot be viewed, which will help the viewer to find the best viewing position.

Preferably, the color of the guidance icon of the screen corresponding to the first viewing angle is the inverse color of the area other than the guiding icon in the screen. More preferably, the red channel value R ₁ , the green channel value G ₁ and the blue channel value B ₁ of the guidance icon of the picture corresponding to the first angle of view are respectively R ₁ =255-R ₁ , G ₁ =255-G _{1, both} B ₁ =255-B ₁ , wherein R ₁ , G ₁ and B _{1 are} respectively the average value of the red channel value of the region other than the index icon in the picture corresponding to the first angle of view, the green channel The average value of the value and the average value of the blue channel value.

Preferably, the color of the guide icon of the picture corresponding to the Nth view is the inverse of the area other than the guide icon in the picture. More preferably, the red channel value R _N , the green channel value G _N and the blue channel value B _N of the guidance icon of the picture corresponding to the Nth angle of view are respectively R _N =255-R _N , G _N =255-G _N , B _N = 255-B _N , where R _N , G _{N ,} and B _{N are} the average values of the red channel values of the region other than the index icon in the picture corresponding to the Nth angle, respectively, and the green channel The average value of the value and the average value of the blue channel value.

Preferably, the position, shape and size of the guide icons of the screen corresponding to the first viewing angle and the Nth viewing angle are the same.

The effect of the present invention is that the control unit controls the panel unit to display the guide icon on the screen corresponding to the first view angle and the Nth view, so that the guide icon can be seen when the viewer is located at the first view and the Nth view. This guides the viewer to find the best viewing position.
