It should be noted that the specific structural form of the light shield 50 is not particularly limited in the present embodiment. The area of the light shield 50 is larger than that of the display lens 50 to completely shield the display lens 50, the light shield 50 is disposed opposite to the display lens 10, and in order to avoid the fixed connection structure affecting the display view of the display lens 50, the fixed connection structure of the light shield 50 and the display lens 10 should be disposed outside the view range.

When the AR glasses are in the form of glasses, the light shield 50, the display lens 10 and the display module 40 are all connected to the frame; when the AR glasses are in the form of a helmet, the light shield 50, the display lens 10 and the display module 40 are all connected in the helmet. In addition, the optical sensor 30 should be disposed outside the visual field of the display lens 10, and the position of the optical sensor 30 is disposed close to the display module 40 for easy connection.

Specifically, in the present embodiment, the photochromic assembly 20 may be a film formed by spraying the photochromic material on the light shield 50, or a film containing the photochromic material may be attached to the light shield 50 by heat pressing or pasting. Alternatively, the photochromic assembly 20 may be formed by doping the photochromic material in the light shield 50, and the photochromic material is doped in the light shield, so that the photochromic material can be prevented from falling off and affecting the use effect caused by long-term use of the AR glasses.

The transmittance of the photochromic film is changed according to the ambient light intensity, and in an environment with stronger ambient light intensity, the transmittance of the photochromic component film is reduced, and the overall transmittance of the light shield 50 is reduced, so that the condition that the visibility of a virtual picture is influenced because excessive light is projected on an AR image is avoided; under the environment that ambient light intensity is weaker, the transmissivity of photochromic component 20 strengthens, and the whole transmissivity of lens hood 50 strengthens to avoid because the transmissivity is low excessively to lead to light too dark, influence the visibility that the external world shows the picture.

Alternatively, the color and transmittance of the base material 51 are set to be gradation. The color of the base material 51 is set to be a gradient color, and the variety of the appearance colors of the AR glasses can be realized. The transmittance of the substrate 51 may also be set to be gradually changed, for example, the transmittance of the substrate 51 gradually increases from top to bottom, so as to effectively remove and filter the scattered light in the external light beam, and make the visual field clear and natural.

Further, the AR glasses further include: a primary color film 52, the primary color film 52 being disposed on the base material 51 for changing the initial color and transmittance of the light shield 50.

At this time, the transmittance of the entire light shield 50 is a superposition of the transmittance of the base material 51, the transmittance of the photochromic film, and the transmittance of the base color film 52.

Alternatively, the color and transmittance of the primary color film 52 are set to be gradation. The primary color film 52 is set to be a gradient color, and the variety of the appearance colors of the AR glasses can be realized. The transmittance of the primary color film 52 can also be set to be gradually changed, for example, the transmittance of the primary color film 52 is gradually increased from top to bottom, so as to effectively eliminate and filter the scattered light in the external light beam, and make the visual field clear and natural.

At this time, the light sensor 30 is disposed between the display lens 10 and the light shield 50, and the light intensity detected by the light sensor 30 is the light intensity of the ambient light after passing through the photochromic assembly 20 and the light shield 50 including the base material 51 and the primary color film 52, so as to ensure that the light intensity received by the light sensor 30 is consistent with the light intensity received by the eyes of the user.

As will be appreciated by those skilled in the art, the display screen belongs to a User Interface (UI).

The following describes the components of the mobile terminal in detail:

the RF circuit can be used for receiving and transmitting signals in the process of information receiving and transmitting or conversation, and particularly, the downlink information of the base station is received and then is processed by the processor; in addition, the data for designing uplink is transmitted to the base station. Typically, the RF circuitry includes, but is not limited to, an antenna, at least one Amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), a duplexer, and the like. In addition, the RF circuitry may also communicate with networks and other devices via wireless communications. The wireless communication may use any communication standard or protocol, including but not limited to Global System for mobile communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, Short Messaging Service (SMS), and the like.

The memory may be used to store software programs and modules, and the processor may execute various functional applications and data processing of the mobile terminal by operating the software programs and modules stored in the memory. The memory may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the mobile terminal, and the like. Further, the memory may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

Other input devices may be used to receive input numeric or character information and generate key signal inputs relating to user settings and function controls of the mobile terminal. In particular, other input devices may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, a light mouse (a light mouse is a touch-sensitive surface that does not display visual output, or is an extension of a touch-sensitive surface formed by a touch screen), and the like. The other input devices are connected with other input device controllers of the I/O subsystem and are in signal interaction with the processor under the control of the other input device controllers.

The display screen may be used to display information input by or provided to the user and various menus of the mobile terminal, and may also accept user input. The display screen may include a display panel and a touch panel. The Display panel may be configured in the form of an LCD (Liquid Crystal Display), an OLED (Organic Light emitting diode), and the like. Touch panels, also called touch screens, touch sensitive screens, etc., can collect contact or non-contact operations on or near by a user and drive corresponding connection devices according to a preset program.

The mobile terminal may also include at least one sensor, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor that may adjust the brightness of the display panel according to the brightness of ambient light, and a proximity sensor that may turn off the display panel and/or the backlight when the mobile terminal is moved to the ear. As one of the motion sensors, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when stationary, and can be used for applications of recognizing the posture of a mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which can be configured on the mobile terminal, further description is omitted here.

Audio circuitry, a speaker, and a microphone may provide an audio interface between a user and the mobile terminal. The audio circuit can transmit the received signal converted from the audio data to the loudspeaker, and the signal is converted into a sound signal by the loudspeaker and then is output; on the other hand, the microphone converts the collected sound signals into signals, which are received by the audio circuit and converted into audio data, which are then output to the RF circuit for transmission to, for example, another cell phone, or to a memory for further processing.

The external devices used by the I/O subsystem to control input and output may include other device input controllers, sensor controllers, and display controllers. Optionally, one or more other input control device controllers receive signals from and/or transmit signals to other input devices. Other input devices may include physical buttons (push buttons, rocker buttons, etc.), dials, slide switches, joysticks, click wheels, light mice (a light mouse is a touch-sensitive surface that does not display visual output, or is an extension of a touch-sensitive surface formed by a touch screen). It is noted that other input control device controllers may be connected to any one or more of the above devices. A display controller in the I/O subsystem receives signals from and/or sends signals to a display screen. After the display screen detects the user input, the display controller converts the detected user input into interaction with a user interface object displayed on the display screen, namely, human-computer interaction is realized. The sensor controller may receive signals from and/or transmit signals to one or more sensors.

The processor is a control center of the mobile terminal, is connected with each part of the whole mobile phone by various interfaces and lines, and executes various functions and processing data of the mobile terminal by running or executing software programs and/or modules stored in the memory and calling data stored in the memory, thereby carrying out the whole monitoring on the mobile phone. Alternatively, a processor may include one or more processing units; alternatively, the processor may integrate an application processor, which primarily handles operating systems, user interfaces, applications, etc., and a modem processor, which primarily handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into the processor.
