The first embodiment:
at present, in order to be distinguished from a plurality of terminal manufacturers, a plurality of manufacturers want to develop more attractive terminals with more characteristics, for example, some manufacturers develop a foldable dual-screen terminal, but the terminal cannot achieve seamless connection of screens when being unfolded. And the application of the flexible screen to the terminal can solve the problem. However, no matter what type of foldable terminal, if the terminal is folded during use, the ambient brightness of the display screens on the two sides of the folded portion may be different, if the screen brightness automatic adjustment mode in the prior art is adopted, the overall brightness of the display screens can only be adjusted, and the display brightness of the folded terminal in the area of the display screen with low ambient brightness may be increased, thereby reducing user experience. In order to avoid this situation, the requirement of different display brightness in different areas of the display screen of the bent terminal is met, as shown in fig. 2, this embodiment provides a method for adjusting the brightness of the terminal.
S201, when the bending of the terminal is detected, determining a bending area on the terminal;
the terminal in this embodiment is a terminal having a bendable function, and the display screen of the terminal is a flexible display screen. In one example, the terminal may be bendable at any location with structural support; in another example, the terminal may be provided with a bendable portion corresponding to the terminal, and non-bendable hardware is avoided.
In practice, it is conceivable that if the bending region on the terminal is not within the range of the display screen of the terminal, the bending region does not divide the display screen into different display sub-regions, so that the detection of the bending of the terminal in S201 of the embodiment includes the detection of the bending of the terminal in the display screen region.
In practice, the bending of the detection terminal can be realized in multiple modes, if all places on the terminal are bendable, parameters (such as parameters of a pressure sensor on the display screen of the terminal) which are used for judging whether the terminal is bent or not on the display screen of the terminal are collected, if the terminal is provided with a bendable part only in a limited place, only whether a preset bendable part on the detection terminal is bent or not is required, the parameters which are used for judging whether the terminal is bent or not on the specific bendable part can be collected, and whether the bendable part is bent or not is judged according to the parameters. In the latter scheme, a sensor for detecting a parameter for determining whether the terminal is bent may be provided only at the bendable portion of the terminal and in the vicinity thereof, which is advantageous for reducing the cost. In addition, if the pressure sensor is adopted, the bending position, the bending direction and the like can be determined according to pressure values at various positions on the display screen of the terminal.
It is conceivable that if the terminal is bent, the bent portion forms an included angle, and light rays emitted from the screen on both sides of the bent portion actually intersect, so in this embodiment, detecting whether the terminal is bent includes: whether the light rays emitted from all parts of the display screen of the terminal have intersection angles or not is detected, and whether the terminal is bent or not is determined according to the detection result.
S202, determining at least two areas obtained by dividing the terminal display screen according to the bent area as display sub-areas on the display screen;
after the terminal is bent, there is necessarily a bending region, and the bending region in S201 may be one, two, and the like, which is not limited by the embodiment.
In S202, the positions and the number of the display sub-regions are determined according to the positions and the number of the curved regions, and when the terminal display screen is divided into at least two display sub-regions according to the curved regions, the curved regions play a role in dividing the display screen into a plurality of display sub-regions (but not necessarily dividing the whole display screen), and the two sides of the curved regions belong to different display sub-regions. For example, as shown in fig. 3, if there is only one bent area of the terminal (area a in fig. 3), the display sub-areas are areas B and C of the display screen on both sides of a boundary line (dotted line in fig. 3) in the bent area. As shown in fig. 4, if there are two bending regions of the terminal (regions D and E in fig. 4), three display sub-regions are: the dotted line on the curved region D to the region at the top of the display screen (F in fig. 4), the region between the dotted line on the curved region D and the dotted line on the curved region E (G in fig. 4), and the dotted line on the curved region E to the region at the bottom of the display screen (H in fig. 4).
The adjustment of the display parameters of the divided display sub-regions can be independent from each other, that is, the terminal can adjust the display parameters of any one or more of the display sub-regions, and the adjustment range of the display parameters of each display sub-region by the terminal can be different.
S203, acquiring the brightness of the current external environment in front of at least one display sub-region;
in order to enable the terminal to adjust the brightness of each display sub-region to meet the brightness change of the external environment and meet the user requirements, the current environment brightness in front of at least one display sub-region needs to be acquired.
In one example, the current ambient brightness in front of all the display sub-regions may be directly obtained in S203. In another example, considering that if the external environment brightness in front of different display sub-regions changes due to bending, it is only necessary to determine the external environment brightness of a region where the relative position with respect to the user changes significantly, specifically, in S203, a display sub-region where the change of the included angle between the display screen and the line of sight of the user after the terminal is bent meets a preset range may be determined first, and only the current external environment brightness in front of the display sub-region is obtained. In another example, considering that when the user uses the terminal, if the user is in a holding state, when the terminal is bent, the external environment brightness of the screen on the top side of the terminal generally changes, and the external environment brightness of the lower portion of the terminal (generally, the side held by the human hand) generally does not change, in S203, it may be determined whether the holding state of the human hand is a vertical holding state, and if so, the current external environment brightness from the bent portion of the terminal to the display screen on the top of the terminal is obtained; and if the holding state of the hand is the horizontal holding state, acquiring the current external environment brightness in front of at least one display sub-area according to the other rules.
In one example, the ambient brightness of the terminal may be collected by a light-sensitive sensor, and the position of the light-sensitive sensor may determine which display sub-region is the ambient brightness collected by the light-sensitive sensor. Specifically, the step of obtaining the current external environment brightness in front of the at least one display sub-region in S203 includes:
and determining the current external environment brightness in front of at least one display sub-area according to the position of the photosensitive sensor on the terminal and the detection data of the photosensitive sensor.
In order to ensure the detection accuracy of the external environment brightness of each display sub-area, the terminal of the embodiment may be provided with a plurality of photosensitive sensors. Further, a set of light sensitive sensors may be provided at least on both the top and bottom of the terminal.
And S204, respectively adjusting the display parameters of each display sub-area according to the current external environment brightness of each display sub-area in at least one display sub-area.
The display parameters in the present embodiment include, but are not limited to, display brightness, color saturation, and the like.
In an example, when the display parameters of each display sub-region are respectively adjusted according to the current external environment brightness of each display sub-region in at least one display sub-region, only the current external environment brightness of each display sub-region may be considered, and the display brightness of each display sub-region before the current bending, the external environment brightness, and the like may not be considered. And determining the adjusted target display brightness of each display sub-area according to the current external environment brightness of each display sub-area in the display sub-areas, and adjusting each display sub-area according to the target adjustment brightness.
Specifically, in this scheme, the step S204 of respectively adjusting the display parameters of each display sub-region according to the current external environment brightness of each display sub-region in at least one display sub-region includes:
acquiring the corresponding relation between the external environment brightness and the target display brightness;
determining the target display brightness of each display sub-region according to the current external environment brightness of each display sub-region in at least one display sub-region and the corresponding relation between the external environment brightness and the target display brightness;
and adjusting the display brightness of each display sub-area to the corresponding target display brightness.
In this scheme, the corresponding relationship between the external environment brightness and the target display brightness may be preset on the terminal, or may be downloaded by the terminal from a server or other terminals through a network in real time, which is not limited in this embodiment.
A scheme of determining the adjusted target display brightness of each display sub-region according to the current external environment brightness of each display sub-region in the display sub-regions and adjusting each display sub-region according to the target adjusted brightness will be described below with reference to fig. 4.
Referring to fig. 4, the display sub-areas on the terminal are F, G, H, assuming that the terminal pair F, G, H obtains the corresponding current external environment luminances a, b, and c, assuming that the corresponding relationship between the external environment luminance and the target display luminance is consulted, finding that the target display luminance corresponding to the external environment luminance a is d, the target display luminance corresponding to the external environment luminance b is e, and the target display luminance corresponding to the external environment luminance c is F, in step S204, the display luminance in the F area is adjusted to d, the display luminance in the G area is adjusted to e, and the display luminance in the H area is adjusted to F.
In another example, after the display sub-regions are determined, it may be further determined which display sub-region and the change of the included angle between the user's sight line meet the preset range, so as to determine which display sub-region may need to adjust the display parameter, for example, in the above example, after it is assumed that the display sub-regions are determined to be F, G, H respectively, it is determined that only the change of the included angle between the F region and the user's sight line before and after the terminal bends this time meets the preset range, the photosensitive sensor at the top of the terminal (on one side of the F region) is controlled to collect the current external environment brightness a, the target display brightness corresponding to the current external environment brightness a is determined to be d according to the corresponding relationship between the external environment brightness and the target display brightness, and the display brightness of the F.
In an example, when the display parameters of each display sub-region are respectively adjusted according to the current external environment brightness of each display sub-region in at least one display sub-region, the display brightness of each display sub-region before the current bending, the external environment brightness, and the like may be combined to adjust each display sub-region on the basis of the current external environment brightness of each display sub-region.
Specifically, the adjusting the display parameters of each display sub-region according to the current external environment brightness of each display sub-region in at least one display sub-region includes:
acquiring a prestored first external environment brightness in front of the display screen before the terminal bends at this time;
determining the change of the external environment brightness of each display subarea in at least one display subarea before and after the terminal is bent according to the first external environment brightness and the current external environment brightness;
and adjusting the current display brightness of each display sub-area according to the change of the external environment brightness of each display sub-area.
In the above scheme, the terminal needs to pre-store the external environment brightness in front of the display screen before bending. The terminal can acquire and store the external environment brightness according to the preset time interval. When necessary, the outside environment brightness at the latest time before the bending is acquired as the above-described first outside environment brightness.
The change of the external environment brightness of each display sub-region before and after the terminal bends at this time may be a value, or may be a change direction (increasing or decreasing).
In an example, the current display brightness of each display sub-region may be adjusted simply according to the direction of the change of the external environment brightness of each display sub-region before and after the terminal is bent this time, and specifically, the adjusting the current display brightness of each display sub-region according to the change of the external environment brightness of each display sub-region includes: if the brightness of the external environment of a certain display subarea in each display subarea is reduced, the display brightness of the display subarea is improved; and if the external environment brightness of a certain display subarea in each display subarea is increased, reducing the display brightness of the display subarea.
The adjustment range of the display brightness of each display sub-region may be a fixed adjustment range, or may be determined by the range of the brightness change of the external environment of each display sub-region before and after the terminal is bent this time.
In another example, the current display brightness of each display sub-region may be adjusted simply according to a change value of the external environment brightness of each display sub-region before and after the terminal bends this time, specifically, the adjusting the current display brightness of each display sub-region according to the change of the external environment brightness of each display sub-region includes:
acquiring the current display brightness of each display sub-region, and acquiring the change value of the external environment brightness of each display sub-region before and after the terminal is bent at this time;
determining the target display brightness of each display sub-region according to the change value of each display sub-region and the current display brightness of each display sub-region;
and adjusting the display brightness of each display sub-area to the corresponding target display brightness.
In an example, the adjustment value of the current display brightness may be determined by the change value of the external environment brightness of each display sub-region before and after the terminal bends this time, for example, if the change value of the external environment brightness of a certain display sub-region before and after the terminal bends this time is a positive number a, the adjustment value of this time is + k, and the display brightness of the display sub-region is adjusted to the sum of the current display brightness and + k. And if the change value of the external environment brightness of a certain display sub-region before and after the terminal bends at this time is a positive number 2a, the current adjustment value is +2k, and the display brightness of the display sub-region is adjusted to be the sum of the current display brightness and +2 k.
In another example, the change value of the external environment brightness of each display sub-region before and after the terminal bends this time is the brightness difference value between the current external environment brightness of each display sub-region and the corresponding first external environment brightness; determining the target display brightness of each display sub-region according to the change value of each display sub-region and the current display brightness of each display sub-region comprises:
and summing the current display brightness of each display sub-area and the brightness difference value corresponding to each display sub-area respectively to obtain the target display brightness of each display sub-area.
A scheme of adjusting the brightness of each display sub-region according to the change value of each display sub-region and the current display brightness of each display sub-region will be described below with reference to fig. 3.
Referring to fig. 3, display sub-areas on the terminal are respectively B and C, assuming that the terminal respectively obtains corresponding current external environment brightness B and C for the B and C, in information pre-stored in the terminal, the screen brightness of the B and C areas before the terminal is bent is a, and the first external environment brightness is d, according to calculation, the target display brightness of the display sub-area B after the terminal is bent is a + B-d, the target display brightness of the display sub-area C after the terminal is bent is a + C-d, the terminal adjusts the screen brightness of the display sub-area B from the current a to the target display brightness a + B-d, and the terminal adjusts the screen brightness of the display sub-area C from the current a to the target display brightness a + C-d.
For the above embodiment, if the user erects the terminal in fig. 3 and the holding area is generally within C, it may be assumed that the external environment brightness of the area C (lower screen of the terminal) generally does not change, and only the current external environment brightness B corresponding to the display sub-area B may be obtained, in the information pre-stored in the terminal, the screen brightness of the area B before the terminal is bent is a, and the first external environment brightness is d, according to the calculation, the target display brightness of the display sub-area B after the terminal is bent is a + B-d, the terminal adjusts the screen brightness of the display sub-area B from the current a to the target display brightness a + B-d, and the screen brightness of the display sub-area C is not adjusted.
In practice, when the user uses the terminal, the ambient brightness acquired by the photosensitive sensor may be incorrect, for example, in the case that the user hides the photosensitive sensor, the ambient brightness acquired by the photosensitive sensor is lower than the actual value. In order to avoid the occurrence of such acquisition errors, in this embodiment, the brightness of the display sub-area may be adjusted by combining with a camera of the terminal.
Specifically, before the display parameters of each display sub-region are respectively adjusted according to the current external environment brightness of each display sub-region in at least one display sub-region, the method further includes:
judging whether the current external environment brightness of each display sub-area is lower than a preset low brightness threshold or higher than a preset high brightness threshold;
if so, acquiring external light source information through a camera of the terminal;
adjusting the display parameters of each display subarea according to the external light source information and the current external environment brightness of each display subarea;
and if not, respectively adjusting the display parameters of each display sub-area according to the current external environment brightness of each display sub-area in at least one display sub-area.
Specifically, the external light source information includes a position (e.g., a relative position with the terminal) and a brightness of the external light source, and the adjusting the display parameters of each display sub-region according to the external light source information and the current external environment brightness of each display sub-region includes:
and respectively adjusting the display parameters of each display sub-region according to at least one of the position and the brightness of the external light source and the current external environment brightness of each display sub-region.
In this example. The low brightness threshold and the high brightness threshold higher than the preset brightness threshold are set according to actual requirements.
Also taking fig. 3 as an example, assuming that for the terminal in fig. 3, the current external environment brightness acquired by the photosensitive sensor at the top of the terminal is lower than the preset low brightness threshold, the terminal starts a camera (a front camera or a rear camera) to acquire external light source information, and determines the position of the external light source according to the external light source information; if it is determined that an external light source exists in front of the display sub-region B in fig. 3, it may be determined that the current external environment brightness acquired by the photosensor is incorrect, then an angle between the region B and the region C and the current external environment brightness of the region C may be acquired, the current environment brightness of the region B is estimated according to the angle and the current external environment brightness of the region C, and then the display parameters of the display sub-regions are respectively adjusted according to the current environment brightness of the display sub-regions.
By adopting the scheme of the embodiment, the adjustment of the brightness of the display screen is not the integral adjustment in the prior art, but different brightness adjustments can be carried out on different display sub-regions on the display screen, so that different requirements of the display sub-regions on the same display screen under different external brightness on the display brightness are met, and the improvement of user experience is facilitated.
