Abstract

The application provides a head-mounted display device comprising a lens frame, lenses, and a display module. The lenses and the display module are arranged at the lens frame. The lenses include firstparts and second parts, wherein the first parts and the second parts are adjacent to each other. The first parts are used for transmitting ambient light and the second parts are used for transmittingthe ambient light. Besides, the first parts are sued for transmitting display light emitted by the display module. Ratios of the light transmittance values of the second parts to the light transmittance values of the first parts are in a threshold range that is between 0.5 and 1.5. The quality of the screen displayed by the head-mounted display device is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a lens and a head-mounted display device. Background technique [0002] Augmented reality (augmented reality, ar) is a kind of application of virtual information to the real world, so that the real environment and virtual objects appear in the same picture or the same space. With the continuous development of AR technology, users can use head-mounted display devices to intuitively see pictures superimposed with virtual objects in the real environment. Conventional head-mounted display devices include lenses. Lenses are critical components used to transmit display and ambient light to the human eye. However, due to the unreasonable structural setting of the lens of the head-mounted display device, the quality of the image displayed by the traditional head-mounted display device is poor, which further affects the comfort of human eyes.
