Abstract
The utility model belongs to the technical field of stereoscopic display, and provides a double-visual angle display apparatus, comprising a displayer, and at least two gratings sequentially pasted on the light-emitting side of the displayer, wherein the grating further comprises a transparent film, and multiple light blocking strips having equal broad widths coated on the upper surface and / or lower surface of the transparent film. Images composed of the odd column stripe shaped pixels of the displayer sequentially pass through the slit of the two gratings, forming a first display picture for a visual angle, images composed of the even column stripe shaped pixels of the displayer sequentially pass through the slit of the two gratings, forming a second display picture for another visual angle, and the visual angle of the first display picture is different from that of the second display picture. Since the at least two gratings are arranged, double-visual angle display can be realized by utilizing any two gratings. Compared with the double-picture visual angle display apparatus in the prior art, the pasting spacings between the gratings and the displayer are increased, thus lowering the production technology requirements of the double-picture visual angle display apparatus, and enhancing the image display effect.
