Detailed Description
The technical solution of the present invention is further described in detail by the accompanying drawings and embodiments.
In order to better understand the information terminal and the working mode thereof provided by the invention, firstly, the visual influence of the external environment light on the user watching the display screen is explained.
When a user watches the display screen, the background environment illumination state has a great influence on the visual effect of the display screen, when human eyes watch any object, the human eyes can adjust the size of the pupil according to the brightness of the object to adapt, the pupil is adjusted to be smaller when the brightness is higher, and the pupil is adjusted to be larger when the brightness is lower. The visual range in which we typically view a display screen is only within 10% of the visual range of our eyes.
For example, when using a 5 "display cell phone, the cell phone is placed about 30cm from the eye, the solid angle of vision of our eye is about 120 degrees, and the range of vision of the eye at 30cm is about 8482cm2And the area of the mobile phone with the 5-inch display screen is not more than 100cm2The display screen of the mobile phone accounts for less than 2% of the visual range of human eyes. As another example, when using a 20 "display computer, the display is placed about 50cm from the eye, where the eye has a 50cm viewing range of about 23562cm2And the area of the 20-inch computer display screen is not more than 1200cm2The computer display screen accounts for less than 6% of the visual range of human eyes. The pupil size of the eye is primarily affected by the background ambient lighting state of the display screen. In order to make the user more comfortable when using the display screen, the brightness of the display screen must be adjusted according to the size of the pupil, i.e. according to the background ambient lighting state of the display screen.
Therefore, under different external environments, if the display screen of the information terminal can be adjusted and displayed according to the display parameters such as brightness, color temperature and the like which are consistent with the external environment, particularly the environment of the visual angle of the user, a certain protection effect can be achieved on the visual health of the user.
The information terminal includes, but is not limited to, a smart phone, a PAD (Personal Digital Assistant), a desktop computer, a television and a projector.
Fig. 1 is a schematic diagram of an information terminal provided in this embodiment, and as shown in the drawing, the information terminal provided in this embodiment includes: the device comprises a display screen 1, a photosensitive device 2, a communication device 3 and a display screen display parameter adjusting unit 4;
the display screen 1 is used for displaying an image of output information of the information terminal. Taking a smart phone as an example, there are various Display screens 1 that can be adopted, and specifically, the Display screens are different depending on the quality and development technology of a Liquid Crystal Display (LCD), and the types of the Display screens generally include TFT, TFD, UFB, STN, and OLED.
The photosensitive device 2 may be specifically an ambient light sensor. When the ambient brightness is high, the LCD using the ambient light sensor will automatically adjust to high brightness. When the external environment is dark, the display can be adjusted to be low brightness, and the brightness can be automatically adjusted. That is, the visibility of the display screen 1 is optimized according to the light level by using the ambient light sensor.
When using an information terminal such as a smartphone or a tablet computer, the distance between the eye position of the user and the information terminal is typically about 30 cm. Since such information terminals are personal products and are displaced with the movement of a person, their backgrounds are generally open, and in this case, the proper placement position of the light sensing device 2 is integrally provided on the information terminal. Under the condition of collecting the state parameters of the background environment of the information terminal, the photosensitive device 2 is preferably arranged on the information terminal in a way that the photosensitive device faces away from the display screen 1. That is, in the case where the display screen 1 is provided on the front surface of the information terminal, the photosensitive device 2 is preferably provided on the rear surface of the information terminal.
Display screen display parameter adjusting unit 4 the display screen display parameter adjusting unit 4 is connected to the photosensitive device 2, the display screen 1 and the communication device 3, respectively. The display parameter adjusting unit 4 adjusts the display parameters of the display screen according to the state parameters of the background environment based on the preset corresponding relationship, so that the display parameters of the display screen are matched with the lighting state of the background environment.
Wherein the display parameters comprise at least a brightness and/or a color temperature.
In this embodiment, a preset corresponding relationship exists between the ambient light conditions of the background environment and the display parameters of the display screen, and data of the preset corresponding relationship may be stored locally in the information terminal or in the cloud. The connection to the cloud is realized by the communication device 3 on the information terminal side.
Specifically, the local storage may be stored in a memory (not shown in the figure) of the information terminal. The memory may be a ROM chip or any other type of solid state non-volatile semiconductor memory. The writing mode into the memory can be realized by a wired input mode, and can also be realized by an interface connected with the memory, such as an infrared interface, a bluetooth interface, a USB interface and the like.
Further, the display parameter adjusting unit 4 includes an adjusting device (not shown in the figure) for changing the preset corresponding relationship to match the display parameters of the display with the lighting state of the background environment. The adjusting device can be a hardware module arranged in the information terminal or a software module arranged on the display screen.
In addition, as shown in fig. 2, in the system connected to the cloud, each information terminal 10 may be connected to the cloud 30 through the network 20, and transmit a parameter of a preset correspondence relationship, in which a display parameter of the display screen 1 matches an illumination state of a background environment in a user view angle range, to the cloud 30 for synchronization. Similarly, the preset corresponding relation parameter matching the display parameter of the display screen 1 with the state of the background environment may also be synchronized through the cloud 30.
Furthermore, the cloud 30 may perform big data statistics and analysis on the preset corresponding relationship data, so as to provide data for the plurality of information terminals 10 accessing the cloud 30. The cloud 30 may perform data analysis on the parameters of the preset correspondence from the plurality of information terminals 10 to generate preset correspondence parameters suitable for the public and the kids, so that each information terminal 10 synchronizes the preset correspondence parameters of the display parameters of the public or the kids, which are required by each information terminal 10, for the display screen and the lighting state of the background environment in the user viewing angle range through the cloud 30.
The process is a self-adaptive adjustment process of the display parameters and the background environment illumination state based on the cloud data. Further, in a preferred aspect of this embodiment, the adjusting device may be further configured to adjust the display parameters of the display screen according to the personalized requirements of the user after the adaptive adjustment is completed.
Specifically, on the basis of the display parameters of the display screen after the self-adaptive adjustment is completed, the user adjusts the display parameters of the display screen through the adjusting device according to the perception of the user on the background illumination and the display parameters of the display screen. After receiving the display parameter adjustment, the information terminal 10 sends the corrected display parameter of the display screen and the lighting state parameter of the background environment in the user view angle range to the cloud 30, and loads the information of the user recorded in the information terminal 10, such as the gender, age, and occupation of the user, in the uploaded data, so as to perform classified statistics on the data, and the cloud 30 changes the preset corresponding relationship, recorded originally, of the user corresponding to the display parameter under the lighting state parameter of the background environment according to the received data, and generates a corrected corresponding relationship.
Therefore, the personalized parameter adjustment of the user can change the universal preset corresponding relation of the cloud.
When a display parameter corresponding relationship of a user in a certain background ambient lighting state is corrected, statistical data corresponding to a general preset corresponding relationship of big data statistics in the background ambient lighting state is also changed. At this time, the pervasive computation needs to consider parameters of preset corresponding relations from a plurality of information terminals and parameters of corrected corresponding relations from information terminals of personalized customization users to perform data analysis, so as to generate a new pervasive preset corresponding relation and a new characteristic preset corresponding relation suitable for the small and popular people.
Therefore, with the data acquisition of personalized adjustment of the display parameters of the information terminal after the self-adaptive parameters are adjusted by a plurality of users, the universally preset corresponding relationship can be continuously and dynamically adjusted along with the data acquisition, and tends to be within a reasonable range which can be accepted by the public.
Similarly, the dynamic adjustment of the preset corresponding relation to the characteristics of the specific audience also changes correspondingly with the display data customized by the user. It should be noted that, different from the universal preset corresponding relationship, the data base number based on the adjustment of the universal preset corresponding relationship is different because the special preset corresponding relationship is only for some specific people, such as women of 20-30 years old, children under 16 years old in beijing area, and the like, and when the special preset corresponding relationship of such people is modified, the modified data sampling range is only for the specific people. Therefore, after the user personalized parameter correction is carried out, the parameter changes of the universal preset corresponding relation and the special preset corresponding relation are different.
The information terminal provided by the embodiment of the invention can adjust the display parameters such as the brightness and the color temperature of the display screen based on the state parameters of the background environment obtained by sampling the illumination of the background environment, so that the display parameters such as the brightness and the color temperature of the display screen are matched with the illumination state of the background environment of the information terminal, the screen display is consistent with the visual perception of a user, the visual fatigue of the user in the using process is effectively relieved, and the visual health of the user is protected. And parameter correction can be carried out according to the personalized requirements of the user, and the display parameters and the preset parameters of background illumination are subjected to universal calculation correction based on the corrected parameters, so that the use habits of the user are better met.
