Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] In practical applications, in order to ensure a user's sense of presence under the premise of reducing image rendering and transmission pressure, a virtual reality (Virtual Reality, VR) head-mounted device can generally provide a foveated rendering function.

[0030] In the foveated rendering function, when the VR headset renders images, it can only provide higher resolution for the image area in the center of the field of view, and provide lower resolution for other image areas. Wherein, the center of the field of view refers to an area around the user's gaze point.

[0031] In order to determine the center of the field of view, the VR headset can track the user's gaze point. In related technologies, the VR head-mounted device...

Abstract

The invention discloses a liquid crystal display and a virtual reality head-mounted device, and belongs to the technical field of virtual reality. The liquid crystal display comprises a first displayarea and a second display area. When the liquid crystal display displays a target image with barrel distortion, the target image is located inside the first display area and outside the second displayarea; in the second display area, a backlight source of the liquid crystal display is an infrared light source. According to the technical scheme, there is no need to independently arrange a specialmechanical structure for bearing the infrared light source for the virtual reality head-mounted device, a user fixation point can be traced, and therefore the size of the virtual reality head-mounteddevice can be reduced.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to a liquid crystal display screen and a virtual reality head-mounted device. Background technique [0002] For a virtual reality (Virtual Reality, VR) technology, presenting an image with a higher resolution can greatly improve the user's sense of presence, but this also puts forward higher requirements on the rendering and transmission of the image. In order to reduce the pressure of image rendering and transmission, more and more VR headsets have introduced the foveated rendering function. In the foveated rendering function, the user's gaze point can be tracked to determine the center of the field of view in the image. In the process of image rendering, a higher resolution may be provided for the image area in the center of the field of view, and a lower resolution may be provided for other image areas. In the process of tracking the user's gaze point, infrared light can...
