Description
Technical Field
The utility model relates to an integrated formation of image 3D shows, more specifically says, the utility model relates to an integrated formation of image 3D display device based on gradual change rectangle pinhole array.
Background
The integrated imaging 3D display has the characteristic of being watched by naked eyes, the shooting and displaying processes are relatively simple, and 3D images with full parallax and full true colors can be displayed, so that the integrated imaging 3D display is one of the main modes of the current 3D display. However, in conventional integrated imaging 3D displays, the picture elements in the micro-image array are all square, i.e. the horizontal pitch of the picture elements is equal to the vertical pitch. In a conventional integrated imaging 3D display, the microlenses are circular, the pinholes are square, and the horizontal pitch of the microlenses and pinholes is equal to the vertical pitch.
For televisions and displays, the ratio of horizontal width to vertical width of the television and display is 16:9, 16: 10 or 4: 3. That is, the ratio of the number of picture elements in the horizontal direction to the number of picture elements in the vertical direction is 16:9, 16: 10 or 4: 3. The disadvantages are that:
(1) the horizontal viewing angle is much smaller than the vertical viewing angle, and the horizontal and vertical viewing angles are inversely proportional to the number of picture elements in the horizontal and vertical directions, respectively.
(2) The ratio of 3D pixels in the horizontal direction to 3D pixels in the vertical direction is 16:9, 16: 10 or 4: 3. Since the total amount of 3D pixels of the 3D image is not high, the number of 3D pixels in the vertical direction is too small, thereby affecting the viewing effect.
For a cell phone, the ratio of the horizontal width to the vertical width of the cell phone is 9:16, 10: 16 or 3: 4. That is, the ratio of the number of picture elements in the horizontal direction to the number of picture elements in the vertical direction is 9:16, 10: 16 or 3: 4. The disadvantages are that:
(1) the ratio of 3D pixels in the horizontal direction to 3D pixels in the vertical direction is 9:16, 10: 16 or 3: 4. Since the total amount of 3D pixels of the 3D image is not high, the number of 3D pixels in the horizontal direction is too small, thereby affecting the viewing effect.
(2) The horizontal and vertical viewing angles are inversely proportional to the number of picture elements in the horizontal and vertical directions, respectively.
