Embodiment Construction
[0044] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0045] In existing VR devices, there is a problem of vergence conflict. Such as figure 1 As shown in Fig. 1, under normal circumstances, the human eye needs to focus both monocular and binocular to see clearly the target object. However, when the 3D scene is presented with the existing 2D display, the incorrect monocular focus will cause convergence. Conflict, multi-focal display is used to solve this problem. In the existing multi-focal plane display VR device, the configuration method of the multiple focal planes is as follows: the focal planes are uniformly placed at a fixed position according to the diopter. Although this method tries to take into account the entire scene, the problem that may be caused is that a target object is...

The invention provides a display device, a display method thereof and virtual reality equipment, and belongs to the technical field of display. The display method is applied to the display device, thedisplay device comprises a displayer and a variable-focus lens, the position of a focal plane can be adjusted through the variable-focus lens, and the display method comprises the steps that the number n of the focal planes is determined according to the display frequency of the displayer and the refresh frequency of a display image; Detecting the display image of the current frame, and determining m salient regions in the display image of the current frame; And determining the positions of n focal planes according to the spatial depths of the m salient regions, and distributing the m salientregions on the n focal planes for display, each salient region being only distributed on one corresponding focal plane, and the spatial depth of the salient region being matched with the position ofthe corresponding focal plane. According to the technical scheme, convergence conflicts can be solved, and the problems that image depths are discontinuous and images are blurred due to the fact thata plurality of focal planes are fixed can be solved.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a display device, a display method thereof, and a virtual reality device. Background technique [0002] In existing VR (Virtual Reality) equipment, there is a problem of convergence conflict. Under normal circumstances, to see the target clearly with the human eye requires the joint action of both monocular and binocular focusing. However, when presenting a 3D scene with an existing 2D display, incorrect monocular focusing will cause convergence conflicts. The focal plane display is used to solve this problem. In the existing multi-focal plane display VR device, the configuration method of the multiple focal planes is as follows: the focal planes are uniformly placed at a fixed position according to the diopter. Although this method strives to take into account the entire scene, it may cause problems: a target object is rendered on a different focal plane, resulting in...
