Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.

Further, when an element is referred to as being "formed on" another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present.
After long-term research and analysis on regional display effect differences of display equipment, the inventor finds that the difference between the light transmittance of a region (a secondary screen region) where a camera under a screen is located and the light transmittance of other regions (a primary screen region) is one of the causes of the problems. Further, in order to ensure the requirement of high light transmittance of the sub-screen area, there are usually differences (e.g., differences in aperture ratio) in the pixel designs of the main and sub-screens, which may result in inconsistent display brightness decay rates of the main and sub-screens. After the display device is used for a period of time, the phenomenon that the brightness of the main screen and the brightness of the auxiliary screen are inconsistent can occur, so that the regional display effect is different.
In order to solve the above problems, the inventor innovatively provides a display device and a control method thereof, by adding a first optical sensor in an auxiliary screen area, a control unit can realize cooperative adjustment of a main screen and an auxiliary screen according to respective corresponding photoelectric signals of the first optical sensor of the auxiliary screen area and a second optical sensor of the main screen area, so that the problem of inconsistent display brightness attenuation rates of the main screen and the auxiliary screen due to different light transmittances is solved, and the display effects of the main screen and the auxiliary screen are ensured to be as consistent as possible. The following further describes the embodiments of the present invention with reference to the drawings.
Referring to fig. 1 and fig. 2, a display device 100 according to an embodiment of the present invention includes a main screen area 20 and a sub-screen area 10, and an opening area 40 for placing an optical device is disposed below a cover plate 30 of the display device 100 corresponding to the sub-screen area 10, where the optical device may be a camera or an optical sensor, and is not limited herein.
Further, referring to fig. 3, the display device 100 may further include a first optical sensor 61, a second optical sensor 62, and a control unit 63. The first optical sensor 61 may be disposed in the sub-screen area 10, the second optical sensor 62 may be disposed in the main screen area, and the control unit 63 is connected to the first optical sensor 61 and the second optical sensor 62, respectively. In some examples, the control unit 63 may be an integrated circuit chip or a processor, for example, a central processing unit of the display device 100 or a display driving chip of the display device, which is not limited herein.
In practical implementation, the first optical sensor 61 may be configured to sense the ambient light incident through the sub-screen area 10 and generate a first photoelectric signal, and the second optical sensor 62 may be configured to sense the ambient light incident through the main screen area 20 and generate a second photoelectric signal. On the basis, the control unit 63 is configured to receive the first photoelectric signal transmitted by the first optical sensor 61 and the second photoelectric signal transmitted by the second optical sensor 62, and determine a first target display parameter and a second target display parameter according to the first photoelectric signal and the second photoelectric signal, so as to adjust the display parameters of the sub-screen area 10 and the main screen area 20, respectively.
It is understood that the first target display parameter is used to adjust the display brightness of the sub-screen 10, and the second target display parameter is used to adjust the display brightness of the main screen 20. The control unit 63 may adjust the display brightness of the sub-screen area 10 and the display brightness of the main screen area 20 synchronously or asynchronously, and for asynchronous adjustment, the display brightness of the main screen area 20 may be adjusted first, or the display brightness of the sub-screen area 10 may be adjusted first, which is not limited herein.
It can be understood that, the display brightness adjustment of the auxiliary screen area 10 and the main screen area 20 by the control unit 63 can be adaptively adjusted along with the change of the first photoelectric signal and the second photoelectric signal, and the first photoelectric signal and the second photoelectric signal change along with the change of the ambient light, so designed, the display device 100 can realize the cooperative adjustment of the display brightness of the main and auxiliary screens according to the change of the ambient light, thereby improving or compensating the brightness difference of the main and auxiliary screens caused by the inconsistent display brightness attenuation rate of the main and auxiliary screens, thereby ensuring that the display effects of the main and auxiliary screens tend to be consistent as much as possible, and avoiding the display effects between the main and auxiliary screens from having larger difference.
In practical implementation, the inventor also finds that, due to the relatively high light transmittance of the sub-screen area 10, after the same ambient light is incident from the sub-screen area 10 and the main screen area 20, the illumination intensities sensed by the first optical sensor 61 and the second optical sensor 62 may be different, so that a deviation may exist between the determined first photoelectric signal and the determined second photoelectric signal. To improve this problem, please refer to fig. 2 in combination, the embodiment of the present invention may further include a grating 50 between the cover plate 30 and the optical device corresponding to the sub-screen area 10.
Further, the grating 50 may be disposed at a position of the opening area 40 close to the cover plate 30, so that no matter whether the optical device is a sensor or a camera, the grating 50 can adjust the light transmittance, thereby ensuring that the light transmittances of the sub-screen area 10 and the main screen area 20 are as consistent as possible, and further ensuring that the intensities of the light sensed by the first optical sensor 61 and the second optical sensor 62 are as same as possible. In the present embodiment, the light transmittance of the grating 50 may be a difference between the light transmittance of the sub screen region 10 and the light transmittance of the main screen region 20.
In practical implementation, the inventor also finds that, most of the common arrangements of the optical devices for the sub-screen area 10 are to arrange the sensor and the camera in the sub-screen area 10 at the same time, which requires increasing the area of the sub-screen area 10, and the increase in the area of the sub-screen area 10 may cause the regional difference of the display effect of the whole display apparatus 100 to become large.
In order to realize flexible placement of different optical devices without increasing the area of the sub-screen area 10, please refer to fig. 3 and 4 in combination, the display apparatus 100 may further include a rotating structure 64 and an image capturing device 65. The image capturing device 65 and the first optical sensor 61 are respectively disposed at two ends of the rotating structure 64, and the rotating structure 64 is used for adjusting the relative positions of the first optical sensor 61 and the image capturing device 65 with respect to the sub-screen area 10, so that the first optical sensor 61 or the image capturing device 65 is located in the opening area 40. In the present embodiment, the camera device 65 may be a front camera, the rotating structure 64 may be a micro motor or the like, and the rotating structure 64 may be controlled by the control unit 63 to adjust the relative positions of the first optical sensor 61 and the camera device 65 with respect to the sub-screen area 10.
In this embodiment, the control unit 63 may be connected with the rotating structure 64 and the imaging device 65. Referring to fig. 4 and fig. 5, when the camera device 65 is turned on, the control unit 63 controls the rotating structure 64 to rotate the camera device 65 to the opening area 40, and when the camera device 65 is turned off, the control unit 63 controls the rotating structure 64 to rotate the first optical sensor 61 to the opening area 40. By such a design, the display device 100 can flexibly set the optical devices of the sub-screen area 10 in different use states, and the front-end camera function and the sub-screen light sensing function can be satisfied without increasing the size of the sub-screen area 10. It will be appreciated that in a typical use situation, the first optical sensor 61 may be located in the open area 40 to achieve ambient light sensing.
On the basis of the above, please refer to fig. 3 and fig. 7 in combination, a method for controlling a display device is also provided, which can be applied to the above display device 100, and which can include the contents described in the following steps S11 to S13. Illustratively, the steps of the method described below may be implemented by the control unit 63 of the display device 100.
In step S11, a first photoelectric signal generated by the first optical sensor according to the sensed ambient light and a second photoelectric signal generated by the second optical sensor according to the sensed ambient light are obtained.
Step S12, obtaining a first target display parameter and a second target display parameter according to the first photoelectric signal and the second photoelectric signal, respectively.
And step S13, adjusting the display parameters of the auxiliary screen area and the main screen area according to the first target display parameters and the second target display parameters respectively.
Therefore, the display brightness difference of the main screen and the auxiliary screen can be cooperatively adjusted, and the display effects of the main screen and the auxiliary screen are ensured to be consistent as much as possible.
On the basis of the above steps, please refer to fig. 4 and 8 in combination, the method may further include the following steps S21 and S22.
And step S21, when the camera device is turned on, controlling the rotating structure to rotate the camera device to the opening area.
In step S22, the control rotation structure rotates the first optical sensor to the opening area when the imaging device is turned off.
For example, the control unit 63 may control the rotating structure 64 to rotate the imaging device 65 to the opening area 40 when detecting that the front imaging function is turned on, and control the rotating structure 64 to rotate the first optical sensor 61 to the opening area 40 when detecting that the front imaging function is turned off. This enables flexible adjustment of the placement position of the optical device without increasing the area of the sub-screen region 10, so as to meet different requirements of the display apparatus 100.
In some examples, the deriving the first target display parameter and the second target display parameter from the first optical signal and the second optical signal described in step S12 may further include: and respectively inputting the first photoelectric signal and the second photoelectric signal into a preset mapping relation model to obtain a first target display parameter and a second target display parameter output by the mapping relation model.
In this embodiment, the preset mapping relationship model may be a mapping relationship model of the ambient light and the display brightness, for example, the mapping relationship model is an ambient light-display brightness curve. In some possible examples, the mapping relationship model may be implemented by steps S31-S33 shown in fig. 9.
Step S31, determine the illumination intensity value of each group of test lights and the display brightness adjustment value corresponding to each illumination intensity value.
For example, the display brightness adjustment value is obtained by processing a brightness adjustment touch operation received by the display device to be tested. Further, the brightness adjustment touch operation may be input by the user through the display device to be tested in different ambient light scenes. It can be understood that the display brightness adjustment value can be obtained by sampling and analyzing as many brightness adjustment touch operations as possible, so that the display brightness adjustment value can be ensured to meet the display requirements of most users as much as possible.
Step S32, determining each illumination intensity value and the corresponding display brightness adjustment value as a two-dimensional array, and mapping the two-dimensional array to a preset plane to obtain a two-dimensional coordinate point.
For example, the preset plane may be a two-dimensional coordinate plane, the abscissa may be the illumination intensity value, and the ordinate may be the display luminance adjustment value.
In step S33, two-dimensional coordinate points in a preset plane are fitted to generate a mapping relation model.
For example, the mapping relation model may be understood as a smooth curve.
In this way, based on the contents described in the above steps S31-S33, when determining the mapping relationship model, the brightness adjustment touch operation input by the user can be taken into account, so as to ensure that the display brightness adjustment value can meet the display requirements of most users, and further ensure that the mapping relationship model matches the actual scene as much as possible when being applied.
In practical implementation, the inventor finds that, after the display brightness adjustment is performed on the main screen and the sub-screen, if the display apparatus 100 is used in the same ambient light scene for a long time, the display effect of the main screen and the sub-screen may be inconsistent again, and please refer to fig. 10, in an alternative embodiment, the adjustment of the display parameters of the sub-screen and the main screen according to the first target display parameter and the second target display parameter described in step S13 may be performed through the following steps S131 to S135.
Step S131, adjusting the display parameters of the auxiliary screen area according to the first target brightness parameter in the first target display parameters to obtain a display parameter adjustment result.
And step S132, determining a sub-screen brightness matrix corresponding to the display parameter adjustment result.
In step S132, the sub-screen luminance matrix may be formed by the luminance values of the pixels in the sub-screen and the coordinate positions of the pixels, and the luminance values in the sub-screen luminance matrix correspond to the pixels in the sub-screen 10 one to one.
Step S133, determining first display brightness attenuation information of the sub-screen area according to the obtained brightness attenuation data of the pixel corresponding to each brightness value in the brightness matrix of the sub-screen area.
For example, brightness decay data of pixels in the sub-screen area 10 may be determined by related driving signals or current data, and the first display brightness decay information may be used to characterize brightness decay of regions of the pixels of the sub-screen area 10, such as which regions of the sub-screen area 10 have faster brightness decay and which regions of the sub-screen area 10 have slower brightness decay.
And S134, correcting a second target brightness parameter in the second target display parameters according to the first display brightness attenuation information to obtain a third target brightness parameter.
For example, the third target brightness parameter may include a plurality of target brightness values at which different control trigger timings exist. The control unit 63 may adjust the display brightness of the main screen area 20 in a stepwise manner according to the control trigger time of different target brightness values.
Step S135, adjusting the display brightness of the main screen area based on the third target brightness parameter, so that the second display brightness attenuation information corresponding to the adjusted main screen area is consistent with the first display brightness attenuation information.
By designing in this way, based on the content described in the above step S131 to step S135, the first display brightness attenuation information of the sub-screen area 10 can be considered when performing the main-sub-screen adjustment, so as to implement the correction of the second target brightness parameter, and thus, when adjusting the display brightness of the main screen area 20 based on the corrected second display brightness attenuation information, the display brightness of the main screen area 20 can be adjusted in a staged manner, so as to ensure that the display brightness attenuation effects of the main and sub-screens are kept as consistent as possible, thereby improving the situation that the display effects of the main and sub-screens are inconsistent when the display device 100 is used for a long time in the same ambient light scene.
In some other embodiments, the manual adjustment of the brightness of the main screen and the sub-screen can be implemented according to the actual requirement of the user, please refer to fig. 11, and the method can further include the following steps S41 and S42.
Step S41, in response to the brightness calibration instruction input by the user, displaying brightness adjustment options for the display device.
As shown in fig. 12, brightness adjustment options may be displayed in the main screen area 20 of the display device 100, including a first brightness adjustment option for the sub-screen area 10 and a second brightness adjustment option for the main screen area 20, which may be brightness bars.
And step S42, responding to the operation instruction of the user for the brightness adjustment option, and adjusting the brightness of the auxiliary screen area and/or the main screen area.
As shown in fig. 12, the user may manually adjust the brightness of the sub-screen area 10 only through the first brightness adjustment option, may manually adjust the brightness of the main screen area 20 only through the second brightness adjustment option, and may manually adjust the sub-screen area 10 and the main screen area 20 through both the first brightness adjustment option and the second brightness adjustment option. And is not limited herein.
It is to be understood that the embodiment of manually adjusting the brightness may be implemented alone, or may be implemented in combination with the first optical sensor 61 and the second optical sensor 62, and is not limited herein. When the schemes of step S41 and step S42 are separately implemented, the first optical sensor 61 may not be installed in the sub-screen area 10, thereby reducing the manufacturing cost of the display apparatus 100.
In summary, according to the display device and the control method thereof provided by the embodiment of the invention, the problem of inconsistent display brightness attenuation rates of the auxiliary screen area and the main screen area due to different light transmittances can be solved by additionally arranging the first optical sensor in the auxiliary screen area, and the display brightness difference of the main screen and the auxiliary screen due to the larger display brightness attenuation rate of the auxiliary screen area is compensated, so that the display effects of the auxiliary screen area and the main screen area are ensured to be consistent as much as possible.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
