Problems solved by technology

However, during the transmission of the light emitted by the above-mentioned display screen along the above-mentioned preset optical path, there will be a certain amount of light loss after passing through each optical element, so that the brightness of the light that finally reaches the human eye is greatly reduced (for example, reduced to about 12% ), affecting the effect of NED

Abstract

The embodiment of the invention provides an optical display system and a display device, which relate to the technical field of optics and are used for reducing light loss generated when light emittedby a display screen in NED equipment passes through an optical element during transmission along a preset light path. The optical display system comprises a display screen, a polarization reflectionlayer and a dimming film layer. The display screen is used for emitting display light. The polarization reflection layer is arranged on the light emitting side of the display screen and used for reflecting light, with the vibration direction perpendicular to the light transmitting axis of the polarization reflection layer, in the display light to form first linearly polarized light. The dimming film layer is arranged on the light emitting side of the display screen and used for converting the first linearly polarized light into second linearly polarized light. The vibration direction of the second linearly polarized light is perpendicular to the vibration direction of the first linearly polarized light. In addition, the polarization reflection layer is also used for transmitting the secondlinearly polarized light. The optical display system is used for realizing near-to-eye display.

Description

technical field [0001] The present application relates to the field of optical technology, in particular to an optical display system and a display device. Background technique [0002] With the continuous development of near-to-eye display (near to eye display, NED) technology, users can realize the display experience of augmented reality (augmented reality, AR) or virtual reality (virtual reality, VR) when using a device using the NED technology. [0003] At present, there are various optical elements in the NED device, and the above-mentioned various optical elements can change the propagating direction of the incident light, thereby forming a certain preset optical path. In this way, the light emitted by the display screen can reach human eyes after passing through the preset optical path, so as to realize the above-mentioned AR or VR display. However, during the transmission of the light emitted by the above-mentioned display screen along the above-mentioned preset opt...
