Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art based on this application belong to the scope of protection of this application.

[0039] With the development of virtual reality (Virtual Reality, VR) technology and augmented reality (Augmented Reality, AR) technology, performance requirements for head-mounted display devices are getting higher and higher. The eye-tracking function applied to head-mounted display devices is gradually becoming a standard configuration of head-mounted display devices because it can provide products with advantages in interaction, display, rendering, and content.

Abstract

The embodiment of the invention provides a display module, a manufacturing method thereof and head-mounted display equipment. The display module comprises a display panel, wherein the display panel comprises a display area and a frame area; the photosensitive unit is located in the frame area; the optical tracking structure comprises an optical lens, a frame used for fixing the lens and a light passing opening formed in the frame, and the light passing opening is used for transmitting light at different positions of an eyeball to the photosensitive unit so as to track the eyeball. In the embodiment of the invention, the photosensitive unit is located in the frame area of the display panel, and the light passing opening in the optical tracking structure is located in the frame of the optical lens. The distance between the light passing port in the optical tracking structure and the photosensitive unit is above the millimeter level, so that the distance between the light passing port and the photosensitive unit is increased, the processing technology difficulty of the light passing port and the photosensitive unit is reduced, and the accurate eyeball tracking function is realized.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display module, a manufacturing method thereof, and a head-mounted display device. Background technique [0002] With the development of virtual reality (Virtual Reality, VR) technology and augmented reality (Augmented Reality, AR) technology, performance requirements for head-mounted display devices are getting higher and higher. The eye-tracking function applied to head-mounted display devices is gradually becoming a standard configuration of head-mounted display devices because it can provide products with advantages in interaction, display, rendering, and content. The head-mounted display device may include a head-mounted VR device, a head-mounted AR device, and the like. [0003] In related technologies, the eye tracking function is integrated on a head-mounted display device, which mainly includes an optical tracking structure, a photosensitive unit, and a lig...
