A kind of prism sheet and its manufacturing method, backlight module and vr display device

Abstract

The invention discloses a prism sheet, a manufacturing method thereof, a backlight module and a VR display device, and relates to the field of display technology, so as to reduce the distortion of images seen by users without increasing the volume of the VR display device. The prism sheet comprises a base material, one side of the base material is a light-incident surface, and the other side is a light-exit surface, and one side of the base material as the light-incident surface is provided with a plurality of pits, and each of the pits is spaced It is provided that each pit includes an opening, a bottom of the pit, and an inclined wall connecting the opening and the bottom of the pit; the opening area formed by the opening is larger than the bottom surface area of ​​the bottom of the pit. The backlight module includes the prism sheet mentioned in the above technical solution. The prism sheet provided by the invention is used in a VR display device.

Description

technical field [0001] The 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, also known as virtual reality display device, applies virtual reality (Virtual Reality, referred to as VR) technology to the display device, enabling users to immerse themselves in a three-dimensional dynamic visual environment and realize human-computer interaction with the VR display device. Experience 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 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 re...

[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
