All other embodiments, which a person of ordinary skill in the art would have, based on the embodiments in this application, come within the scope of protection of this application.
The terms "first," "second," "third," "fourth" and the like in the description and in the claims of this application and in the above-described figures, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Generally, the VR device includes an optical module, and when a user wears the VR device at a designated position, a visual focus of the optical module falls on a screen of the VR device, so that the user can have a clear visual effect when browsing a video played on the screen. However, when the VR device is in an environment with strong light, if the user removes the VR device, the optical module of the VR device will collect the light onto the screen, so that the screen is burned by the collected light.
Based on the technical problems, the invention concept of the application is as follows: when the VR device is in an unworn state and the ambient illumination intensity is determined to be higher than the set light intensity threshold, light transmitted through the optical module of the VR device is focused on a screen of the VR device, and the screen is burned. In this case, the first position of the current lens module of the VR device is adjusted so that the focal point of the light passing through the lens module at the adjusted second position is located outside the screen of the VR device. Therefore, the screen can not be burnt, the service life of the screen is prolonged, and after-sale defects are reduced.
The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
The embodiment of the application provides a lens module adjusting method of VR equipment, which is applied to the VR equipment. As shown in fig. 1, the VR device may include, but is not limited to, a pair of optical modules 101, and each optical module 101 may include, but is not limited to, at least two convex lenses disposed at intervals (each optical module 101 includes two convex lenses in fig. 1). When the VR device is in a worn state by the user, the VR device is in a worn state, and the user falls on the screen 102 of the VR device through the visual focus of the optical module 101. Thus, the user can have a clear visual effect when browsing the video played on the screen 102.
For example, a user may wear a VR device to browse to a game video on screen 102, immersed in a virtual game world. For another example, the user may wear a VR device to browse movie videos on the screen 102, immersed in a virtual movie world.
Specifically, as shown in fig. 2, a method for adjusting a lens module of a VR device provided in an embodiment of the present application includes:
s201: the VR device detects whether the current state of the VR device switches from the worn state to the unworn state, and if so, S202 is performed.
For example, the inside of the VR device may be provided with a distance sensor that detects that the current state of the VR device switches from the worn state to the unworn state when the distance sensor detects that the distance of the obstacle switches from less than the set distance threshold to greater than the set distance threshold.
Alternatively, the inner side of the VR device may be provided with a first light intensity sensor, and when the first light intensity sensor detects that the light intensity is switched from less than the set light intensity threshold to greater than the set light intensity threshold, it detects that the current state of the VR device is switched from the worn state to the unworn state.
S202: the VR device determines whether the current ambient light intensity is above a set light intensity threshold, and if so, performs S203.
Alternatively, the outer side of the VR device may be provided with a second light intensity sensor, and the VR device may detect whether the ambient light intensity is greater than a set light intensity threshold through the second light intensity sensor.
It should be noted that the second light intensity sensor may be separately and independently disposed from the above-mentioned distance sensor or the first light intensity sensor, and the second light intensity sensor may also be integrated with the above-mentioned distance sensor or the first light intensity sensor on the same chip, which is not limited herein.
S203: the VR device adjusts the first position of the current lens module of the VR device so that the focal point of the light beam passing through the lens module at the adjusted second position is located outside the screen 102 of the VR device.
Specifically, the VR device may include a motor and a transmission, where the motor, the transmission, and the lens module are connected in sequence. When the lens module includes two convex lenses, the VR equipment can adjust the interval between the two convex lenses through the motor drive transmission mechanism of the VR equipment to adjust the first position of the current lens module.
For example, as shown in fig. 3, the VR device may reduce the distance between the two convex lenses by a motor-driven transmission of the VR device such that the lens module is in the second position. In this way, the light passes through the focal point behind the lens module at the adjusted second position, and is located behind the screen 102 of the VR device.
As another example, as shown in fig. 4, the VR device may increase the distance between the two convex lenses by driving the transmission mechanism by the motor of the VR device, so that the lens module is in the second position. In this way, the light passes through the focal point behind the lens module at the adjusted second position, and is located in front of the screen 102 of the VR device.
In summary, the embodiments of the present application provide a lens module adjusting method of a VR device, where when the VR device is in an unworn state and it is determined that the ambient light intensity is higher than the set light intensity threshold, the light passing through the optical module 101 of the VR device is focused on the screen 102 of the VR device, so that the screen 102 may be burned. In this case, the first position of the current lens module of the VR device is adjusted so that the focal point of the light passing through the lens module in the adjusted second position is located outside the VR screen 102. Thus, the screen 102 is not burned, the service life of the screen 102 is prolonged, and after-sales defects are reduced.
In addition, the screen 102 may be a liquid crystal display, and on the basis of the embodiment corresponding to fig. 2, the method provided in the embodiment of the present application further includes: the VR device controls the periodic switching of the liquid crystal layer 503 of the liquid crystal display upon determining that the ambient light intensity is above the set light intensity threshold. Wherein, when the liquid crystal layer 503 of the liquid crystal display is closed, light irradiates to the front surface of the liquid crystal display; when the liquid crystal layer 503 of the liquid crystal display is turned on, light can pass through the liquid crystal layer 503 to reach the back surface of the liquid crystal display.
It can be appreciated that when the lcd is turned on, light can penetrate the lcd layer 503 after passing through the front of the lcd to reach the back of the lcd, and at this time, the temperature of the back of the lcd increases; when the liquid crystal layer 503 of the liquid crystal display is turned off, light is made unable to penetrate the liquid crystal layer 503 after passing through the liquid crystal layer 503 of the liquid crystal display when the liquid crystal layer 503 of the liquid crystal display is turned off, and stays in the liquid crystal layer 503 of the liquid crystal display when the temperature of the liquid crystal layer 503 of the liquid crystal display is raised. In this way, the liquid crystal layer 503 of the liquid crystal display screen is periodically controlled repeatedly to be turned on and off, so that the front and back surfaces of the liquid crystal display screen are uniformly irradiated by light and have uniform temperature, and the front or back surface of the liquid crystal display screen can be further prevented from being burnt by light.
Specifically, as shown in fig. 5, the liquid crystal display includes an upper polarizer 501, a liquid crystal layer 503, and a lower polarizer 502, wherein the liquid crystal layer 503 is provided with a thin film transistor array 504. When the VR device determines that the ambient illumination intensity is higher than the set light intensity threshold, the VR device controls the periodic on-off of the thin film transistor array 504, so that the liquid crystal layer 503 is periodically turned on and off. When the thin film transistor array 504 is turned on, light can penetrate through the liquid crystal layer 503 after passing through the upper polarizer 501 to reach the lower polarizer 502, and at this time, the temperature of the lower polarizer 502 is increased; when the thin film transistor array 504 is turned off, the light cannot penetrate the liquid crystal layer 503 after passing through the upper polarizer 501, and stays on the upper polarizer 501, and at this time, the temperature of the upper polarizer 501 increases. In this way, the periodic on-off of the thin film transistor array 504 is controlled repeatedly and periodically, so that the top and bottom of the liquid crystal display screen are uniformly irradiated by light and have uniform temperature, and the top or bottom of the liquid crystal display screen can be further prevented from being burnt by light.
In addition, on the basis of the embodiment corresponding to fig. 2, the method provided in the embodiment of the application may further include: the VR device controls the backlight of the screen 102 to be turned off upon determining that the ambient light intensity is above the set light intensity threshold.
In this way, the temperature rise of the screen 102 can be further avoided, and the front or back of the screen 102 can be further prevented from being burned by light.
In addition, on the basis of the embodiment corresponding to fig. 2, the VR device may further include a fan, and when the ambient light intensity is higher than the light intensity threshold, the method provided in the embodiment of the present application may further include: the VR device controls the fan to turn on.
It will be appreciated that the fan may dissipate heat from the VR device when turned on. In this way, the temperature of the screen 102 is further prevented from rising, thereby preventing the top or bottom of the screen 102 from being burned by light. It should be noted that, the VR setting may control the fan to reach the maximum rotation speed, so as to further avoid the temperature rise of the screen 102.
In addition, in addition to the embodiment corresponding to fig. 2, S203 further includes: when the VR equipment determines that the ambient illumination intensity is higher than the light intensity threshold, recording the current first position of the lens module of the VR equipment; then, as shown in fig. 6, after S203, the method provided in the embodiment of the present application further includes:
s204: the VR device performs S205 upon detecting whether the state of the VR device is switched from the unworn state to the worn state, and if so.
For example, when a distance sensor on an inside of the VR device detects that a distance of an obstacle is switched from greater than a set distance threshold to less than the set distance threshold, a current state of the VR device is detected to be switched from an unworn state to a worn state.
Alternatively, the inner side of the VR device may be provided with a first light intensity sensor, and when the first light intensity sensor detects that the light intensity is switched from being greater than the set light intensity threshold to being less than the set light intensity threshold, it is detected that the current state of the VR device is switched from the unworn state to the worn state.
S205: the VR device determines if the current ambient light intensity is below a light intensity threshold and if so, performs S206.
S206: the VR device adjusts the lens module from the second position to the first position.
Similarly, when the lens module includes two convex lenses, the VR device may adjust the distance between the two convex lenses through the motor driving transmission mechanism of the VR device, so as to adjust the current lens module from the second position to the first position.
Based on the above-mentioned S204-S206, when the VR device detects that the state of the VR device is switched from the unworn state to the wearable state, it indicates that the user wants to use the VR device normally, and when the current ambient illumination intensity is lower than the light intensity threshold, it indicates that the screen 102 is not burned even if the lens module of the VR device converges light on the screen 102. At this time, the lens module is adjusted from the second position to the first position, so that the user can normally use the VR device to browse the video played on the screen 102.
Further, when the VR device determines that the current ambient light intensity is lower than the light intensity threshold, if the backlight of the screen 102 is turned off, the backlight of the screen 102 is controlled to be turned on, so that the user can use the VR device to browse the video played on the screen 102 normally.
In addition, when the VR device determines that the current ambient light intensity is lower than the light intensity threshold, if the periodic switching of the liquid crystal layer 503 of the liquid crystal display is being controlled periodically, the periodic switching of the liquid crystal layer 503 of the liquid crystal display is stopped, so that the user can browse the video played on the screen 102 by using the VR device normally.
In addition, when the VR equipment determines that the current ambient illumination intensity is lower than the light intensity threshold, if the fan is detected to be in an on state, the fan is controlled to be turned off, so that energy conservation and environmental protection are achieved.
In addition, in the process of adjusting the lens module from the second position to the first position, the method provided by the embodiment of the application further includes: the VR device generates a first prompt for indicating that the diopter of the VR device is recovering, and triggers the screen 102 to continuously display the first prompt in the process of adjusting the lens module from the second position to the first position.
It will be appreciated that the user may view a first prompt on the screen 102, which may prompt the user that the diopter of the VR device is recovering.
In a possible specific implementation manner, on the basis of the embodiment corresponding to fig. 2, the method provided in the embodiment of the present application further includes: when the ambient illumination intensity is higher than the light intensity threshold, the VR device sends second prompt information for indicating that the VR device is under light irradiation to the user terminal.
It will be appreciated that the user may browse the second prompt at the user terminal (e.g., a mobile phone or tablet) and the second prompt may prompt the user that the VR device is under light, so that the user may move the VR device to a position where the light is dim, and may further avoid burning the top or bottom of the screen 102 with light.
