In the transmission process of light emitted by the display screen, the light needs to pass through various optical devices such as lenses, the optical devices can reflect the light, and the reflected light can irradiate the display screen. The display screen is provided with a plurality of optical surfaces, for example, the reflection proportion of each optical surface is 4% -5%, the number of the accumulated reflected light rays of the optical surfaces is large, the reflected light rays form stray light, and the stray light enters human eyes, so that an imaging picture obtained by a user is unclear, and even ghost images exist.
In order to solve the above problem, referring to fig. 1, the present invention provides an optical module, including: a display screen 10, a first phase retarder 20, a first line polarizer 30 and an imaging mirror group 40. The display screen 10 is used for emitting light 110, and a first phase retarder 20, a first linear polarizer 30 and an imaging lens group 40 are sequentially arranged in the propagation direction of the light 110. The phase retarder is used to change the polarization state of the light 110, for example, to convert linearly polarized light into circularly polarized light, or to convert circularly polarized light into linearly polarized light. The first linear polarizer may be understood as a polarizer, and the light ray 110 passing through the first linear polarizer is converted into a light ray 110 in a linear polarization state. The imaging optics 40 is used to resolve the light 110, i.e. to magnify and transmit the light 110. The display principle of the display screen 10 includes various display principles. For example, the principle of the display screen 10 includes an lcd (liquid Crystal display) lcd, or an led (Light Emitting Diode), an OLED (Organic Light-Emitting Diode), a Micro-OLED (Micro-Organic Light-Emitting Diode), an uled (ultra Light-Emitting Diode), or a dmd (digital Micro-mirror device) digital Micromirror chip.
The light 110 emitted by the display screen 10 may be linearly polarized light, circularly polarized light, or natural light, and in order to protect the display screen 10, a light-emitting surface of the display screen 10 is provided with a protective glass. The light rays 110 are all converted to linearly polarized light when passing through the first linear polarizer.
The first phase retarder 20 and the first linear polarizer 30 are sequentially arranged along the propagation direction of the light ray 110, the first linear polarizer 30 has a transmission axis, and an included angle between the transmission axis of the first linear polarizer 30 and the fast axis of the first phase retarder 20 is 45 degrees; the included angle may be positive 45 ° or negative 45 °. The first phase retarder 20 has a fast axis and a slow axis. The first linear polarizer is transparent in the same direction as the transmission axis of the first linear polarizer 30, and is opaque in the direction perpendicular to the transmission axis of the first linear polarizer.
The imaging lens group 40 is disposed on a side of the first linear polarizer 30 facing away from the display screen 10. The imaging lens group 40 may include a single lens, or may include more than two lenses. The imaging lens assembly 40 has a plurality of optical surfaces, and the light ray 110 is reflected when the light ray 110 passes through the imaging lens assembly 40.
In this embodiment, the light 110 emitted from the display panel 10 sequentially passes through the first phase retarder 20 and the first linear polarizer 30, and when the light 110 passes through the imaging lens assembly 40, the light 110 is reflected, and this portion of the light 110 is the stray light 430. The stray light 430 travels in a reverse direction along the initial path of travel of the light 110. The stray light 430 first passes through the first linear polarizer 30, and the stray light 430 is converted into the linearly polarized light 110. The stray light 430 continues to propagate through the first retarder 20, and under the action of the first retarder 20, the stray light 430 in the linear polarization state is converted into a circular polarization state, which may be left-handed polarized light or right-handed polarized light. The stray light 430 is transmitted and irradiated on the display screen 10, and under the action of the display screen 10, the stray light 430 is reflected again, at this time, the rotation direction of the light ray 110 in the circular polarization state is changed, the left-hand polarized light is converted into the right-hand polarized light, and the right-hand polarized light is converted into the left-hand polarized light. The light 110 in the circularly polarized state passes through the first retarder 20 again, and then is converted from the circularly polarized state to the linearly polarized state, at this time, the vibration direction of the stray light 430 in the linearly polarized state is orthogonal to the transmission axis direction of the first linear polarizer, and the stray light 430 cannot pass through the first linear polarizer. Therefore, the stray light 430 cannot enter the imaging lens assembly 40, and similarly, the stray light 430 cannot enter human eyes of a user, so as to ensure that the user obtains an imaging picture with higher definition.
In one embodiment, to reduce the stray light 430 from entering the human eye, the polarization state of the stray light 430 needs to be changed. In order to effectively accomplish the polarization state switching of the stray light 430, the first phase retarder 20 is provided as a quarter-wave plate. Thus, when the light ray 110 passes through the quarter-wave plate, the light ray 110 may be converted from a circular polarization state to a linear polarization state. The first phase retarder 20 may be a separate optical device or a film structure. When the first phase retarder 20 is an independent optical device, it is fixed between the display screen 10 and the imaging lens group 40 through other components, such as a lens barrel, a slot is disposed on an inner wall of the lens barrel, and the first phase retarder 20 is clamped in the slot.
In one embodiment, the mounting positions of the first phase retarder 20 and the first polarizer 30 can be selected from various options, such as the first phase retarder 20 and the first polarizer 30 are disposed on the light emitting surface of the display screen 10; that is, the first phase retarder 20 and the first line polarizer 30 are disposed in attachment to the display screen 10. Therefore, the optical devices between the display screen 10 and the imaging lens group 40 can be reduced, and the structure is simpler. In addition, optical devices between the display screen 10 and the imaging lens group 40 are reduced, and light paths are compressed, so that the optical module is favorably reduced in overall size.
For another example, the first phase retarder 20 and the first line polarizer 30 are spaced apart along the propagation direction of the light ray 110. The first retarder 20 and the first wire polarizer 30 may thus be separate optical devices. The optical module is provided with a lens barrel, a clamping groove is arranged on the inner wall of the lens barrel, and the first phase delayer 20 and the first linear polarizer 30 are clamped in the clamping groove.
In one embodiment, to facilitate the installation of the first phase retarder 20 and the first wire polarizer 30, the first phase retarder 20 and the first wire polarizer 30 are film structures, and the first phase retarder 20 and the first wire polarizer 30 are disposed on the display screen 10; therefore, the mode of attaching or film coating can be adopted, the operation of the attaching mode is simple, and the production is facilitated. The film coating mode can make the arrangement of the first phase retarder 20 and the first linear polarizer 30 more firm, and improve the compactness of the film layer.
Furthermore, the first retarder 20 and the first linear polarizer 30 are film structures, except that the first retarder 20 and the first linear polarizer 30 are disposed on the display screen 10, and the first retarder 20 and the first linear polarizer 30 are disposed on the imaging lens assembly 40. Similarly, the position of the imaging lens group 40 can also adopt an attaching mode, and a film coating mode can also be adopted, so that the attaching mode is simple in operation and beneficial to production. The film coating mode can make the arrangement of the first phase retarder 20 and the first linear polarizer 30 more firm, and improve the compactness of the film layer.
In one embodiment, the first phase retarder 20 and the first line polarizer 30 are mounted on a mounting surface, and the mounting surface is one of a plane, a sphere, an aspheric surface, a free-form surface and a cylinder. It is understood that the first phase retarder 20 and the first line polarizer 30 may be installed on optical surfaces of various surface types. So that the first phase retarder 20 and the first line deflector 30 can be effectively adapted to the position of the installation surface.
In one embodiment, the light ray 110 may be refracted within the imaging optics 40. Specifically, the imaging lens group 40 includes a first lens 410 and a second lens 420, the first lens 410 is disposed on a side of the first linear polarizer 30 facing away from the display screen 10, and the second lens 420 is disposed on a side of the first lens 410 facing away from the display screen 10; the optical module further comprises a second phase retarder 50, a third phase retarder 60, a polarization reflector 70 and a second linear polarizer 80 which are sequentially arranged along the propagation direction of the light ray 110, wherein a first lens 410 is arranged between the second phase retarder 50 and the third phase retarder 60, a second lens 420 is arranged on one side, away from the display screen 10, of the second linear polarizer 80, a light splitting piece is arranged between the second phase retarder 50 and the first lens 410, the transmission axis of the polarization reflector 70 is orthogonal to the transmission axis of the first linear polarizer 30, and the transmission axis of the polarization reflector 70 is parallel to the transmission axis of the second linear polarizer 80. The fast axis of the second phase retarder 50 forms an angle of 45 degrees with the direction of the transmission axis of the first linear polarizer 30, and the fast axis of the second phase retarder 50 is orthogonal to the fast axis of the third phase retarder 60. After the display screen 10 emits the light 110, the light 110 is converted into a linear polarization state after passing through the first linear polarizer 30. After the light 110 in the linear polarization state passes through the second phase retarder 50, the linear polarization state is converted into the light 110 in the circular polarization state. After the light ray 110 in the circular polarization state is emitted to the light splitting member, at least a part of the light ray 110 passes through the light splitting member. After the light 110 continues to be transmitted, the light is converted into linearly polarized light by the third phase retarder 60, the vibration direction of the linearly polarized light is orthogonal to the transmission axis direction of the polarizing reflector 70, and the linearly polarized light 110 is reflected by the polarizing reflector 70. The light 110 is reflected by the third retarder 60, the light 110 is converted into circularly polarized light again, the light 110 is reflected again after the circularly polarized light passes through the light splitting element, at least part of the light 110 is emitted to the third retarder 60 again, and at this time, the rotation direction of the circularly polarized light is changed, for example, the left-handed polarized light is converted into the right-handed polarized light, and the right-handed polarized light is converted into the left-handed polarized light. The light ray 110 passes through the third phase retarder 60 again and is converted into linearly polarized light, and the linearly polarized light is transmitted through the polarization reflector 70 while the vibration direction of the linearly polarized light is the same as the transmission axis direction of the polarization reflector 70. The transmission axis of the polarizing reflector 70 is parallel to the transmission axis of the second linear polarizer 80, and the linear polarization state of the light ray 110 is further ensured by the second linear polarizer 80 after the light ray 110 passes through the polarizing reflector 70. It can be seen that the light 110 can be efficiently refracted in the imaging lens group 40.
In one embodiment, the light splitter is a transflective film disposed on the light incident surface of the first lens 410. The transflective film ensures that a portion of light ray 110 passes through and a portion of light ray 110 reflects.

The combination of the first lens 410 and the second lens 420 can ensure effective convergent imaging of the light 110. In addition, the light incident surface of the second lens 420 is a plane, which is more flat and convenient for the third phase retarder 60, the polarizing reflector 70 and the second polarizer 80 to be attached to each other.
