Abstract

The invention discloses a display module and a manufacturing method thereof and a head-mounted display device. A photosensitive unit is integrated in an array substrate in a frame area of a display panel, and an optical tracking structure comprising a bump and a light passing port corresponding to the photosensitive unit is arranged in the frame area; the distance between the first surface of the bump and the array substrate is greater than the distance between the surface of a cover plate in a display area and the array substrate, so that reflected light of different positions of eyes is transmitted to the photosensitive unit by virtue of the optical tracking structure to realize an eyeball tracking function, the display area is ensured to be light and thin favourably, and the eyeball tracking function is realized.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates 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, the performance requirements of VR devices are getting higher and higher. The eye-tracking function applied to head-mounted VR devices is gradually becoming the standard configuration of head-mounted VR devices because it can provide products with advantages in interaction, display, rendering, and content. [0003] Currently, head-mounted VR products on the market are beginning to be thinner and lighter for user experience. Integrating the eye-tracking structure in the head-mounted VR device is difficult to take into account the thin and light design of the product. Contents of the invention [0004] Embodiments of the present invention provide a display module, a manufacturing...
