Problems solved by technology

[0005] However, in the existing grid-type naked-eye 3D display technology, the left eye of the observer can only view a part of the images displayed on the 2D flat panel display, and the right eye of the observer can only view part of the images displayed on the 2D flat panel display. Part of the image in the image, so the resolution of the 3D image that the viewer actually sees is reduced to half of the 2D image display

Embodiment Construction

[0024] Various embodiments according to the present invention will be described in detail with reference to the accompanying drawings. Here, it is to be noted that, in the drawings, the same reference numerals are assigned to components having substantially the same or similar structures and functions, and repeated descriptions about them will be omitted.

[0025] First, refer to figure 1 To describe the problems existing in the prior art and the principles of the technical solutions of the prior art for solving the technical problems.

[0026] figure 1 The principle of the solution according to the prior art is illustrated, where the reference numbers are drawn out with dotted lines and the line of sight is indicated with solid lines.

[0027] As described in the background, in the existing screen grid type glasses-free 3D display technology, a glasses-free 3D display device includes a display unit 110 and a grating unit 120 . Specifically, the display unit 110 is, for exa...

Abstract

The invention discloses a composite image displaying method and device. The method comprises the steps of displaying images from a first image source in first display area collection of a display unit and displaying images from a second image source in a second display area collection of the display unit in the first time position, displaying in a reverse mode in the second time position, partly or completely shielding backlight light rays emitted by the display unit through an optical grating unit so as to enable the images, from the first image source, displayed in the display unit to be displayed before a first eye of a user in the first time position and enable the second images, from the second image source, displayed in the display unit to be displayed before a second eye of the user in the second time position. Consequently, a composite image formed by the images from the first image source and the images from the second image sources is displayed before the user. Thus, naked eye visual sense is made to have a 3D display effect on the condition that the resolution ratio is not reduced, and user experience is sufficiently improved.

Description

technical field [0001] The present invention relates to the technical field of image display, and more particularly, the present invention relates to a composite image display method and device. Background technique [0002] With the continuous development of display technology, traditional methods and corresponding devices for displaying two-dimensional (2D) images are increasingly unable to meet the needs of users. In order to improve the viewing experience of users, a variety of three-dimensional (3D) display technologies have been proposed in recent years, for example, 3D display technology through 3D glasses, or naked-eye 3D display technology that allows users to experience stereoscopic sensation without using 3D glasses. . [0003] As the mainstream technology of naked-eye 3D display, the so-called barrier barrier-type naked-eye 3D display (or parallax barrier) technology is usually adopted. The parallax barrier technology has been researched by the engineers of Sha...
