Problems solved by technology

Because LED display technology is different from LCD and PDP display technologies, especially the arrangement of its pixels is not suitable for the application of naked-eye three-dimensional display technology, thus hindering the application of naked-eye three-dimensional display technology on LED displays

Embodiment Construction

[0045] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0046] figure 1 It is the overall schematic diagram of the naked-eye three-dimensional display of the LED screen

[0047] 1 is the LED screen, which adopts a special pixel arrangement. 2 is a slit grating placed parallel to the front of the LED screen. The grating parameters and the LED screen meet the optical parameter matching relationship, so that the left and right eyes can just see images from different viewpoints through the slits, thereby achieving stereoscopic display in the display area. 3 is the slit of the slit grating, 4 is the dark fringe, 3 and 4 together form a grating pitch of the slit grating, and 5 is a computer, which is used to output naked-eye stereoscopic images and stereoscopic videos.

Abstract

The invention discloses a manufacture method of a slit grating for LED (Light Emitting Display) screen naked-eye stereo display. The method comprises the following steps: arranging the pixels of an LED screen, which are matched with the slit grating; calculating parameters of the slit grating and the naked-eye stereo display area of the LED screen; and manufacturing and positioning the slit grating. According to the pixel arrangement and virtual pixel display mode disclosed by the invention, the display pixels of the display mode is 3 times of the common display during naked-eye stereo display, and the detuning phenomenon of a horizontal resolution and a vertical resolution is reduced. The proposed optical parameter matching relationship of the naked-eye stereo display is more suitable for the LED screen, the angle of inclination of the adopted slit grating avoids a pixel discrimination problem, and meanwhile, the manufacture method has the advantages of lower cost and higher precision.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic display, relates to a manufacturing method of a slit grating for naked-eye stereoscopic display on an LED screen, and belongs to the stereoscopic display technology. Background technique [0002] Traditional stereoscopic image display needs to wear auxiliary tools such as polarized glasses, complementary color glasses or liquid crystal glasses, so the human eyes are completely occupied, and it is very inconvenient for the human eyes to do other things not related to the screen except watching the screen. The three-dimensional display technology (comprising three-dimensional helmet) wearing glasses, although its three-dimensional display effect is particularly good, is not applicable in many occasions. Autostereo image display technology does not need to wear glasses, because stereoscopic display is compatible with other two-dimensional displays. Since the user's eyes are not restricted when ...
