[0003] Generally speaking, the area of the lens between the display screen and the human eye in a VR display device is relatively large compared to the area of the display screen, so that the outgoing direction of the image displayed on the display screen can be adjusted, and the distortion of the image seen by the user can be reduced. Make the image seen by the user more realistic; however, this method of reducing the distortion of the image seen by the user is based on the premise of increasing the lens area in the VR display device, which will make the volume of the VR display device larger , is not conducive to the wearable VR display device

Abstract
The invention discloses a prismatic lens and a manufacturing method thereof, a backlight module group and a VR display device, relates to the technical field of display, and aims at reducing distortion of an image seen by a user without increasing the size of the VR display device. The prismatic lens comprises base material. One side of the base material is a light incident surface, and the other side is a light emergent surface. One side acting as the light incident surface of the base material is provided with multiple pits. All the pits are arranged in a spacing way. Each pit comprises an open part, a pit bottom part and an inclined wall part which connects the open part and the pit bottom part. The open area formed by the open part is greater than the bottom area of the pit bottom part. The backlight module group comprises the prismatic lens provided in the technical scheme. The prismatic lens is applied to the VR display device.
Description
Technical field [0001] The present invention relates to the field of display technology, in particular to a prism sheet and a manufacturing method thereof, a backlight module and a VR display device. Background technique [0002] VR display device is also called virtual reality display device. It applies virtual reality (Virtual Reality, VR) technology to the display device to enable users to be immersed in a three-dimensional dynamic visual environment, and to achieve human-computer interaction and experience with the VR display device To the immersive feeling. [0003] Generally speaking, the area of the lens between the display screen and the human eye in a VR display device is relatively large relative to the area of the display screen, so that the direction of light emission of the image displayed on the display screen can be adjusted to reduce the distortion of the image seen by the user. Make the images seen by the user more realistic; however, this method of reducing t...
