When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present application. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
Fig. 1 is a flowchart illustrating a screen brightness adjusting method according to an exemplary embodiment, where the adjusting method is applied to a terminal, as shown in fig. 1, and may include the following steps:
in step 101, a steep region and a standard region of brightness within a display area are determined.
In this embodiment, the display area is an area with pixels and a display function in the screen, and the steep area and the standard area are combined to form a complete display area. Under the condition of the same input parameters, the light emitting degrees of the pixel points corresponding to the steep change area and the pixel points corresponding to the standard area are different, so that the brightness of the steep change area is different from that of the standard area.
In one embodiment, the abrupt change region and the standard region may be fixed. For example, the area for showing the anchor icon within the display area is always determined as the abrupt change area, and the other areas except the abrupt change area are determined as the standard areas. The area showing the fixed icon may include an area showing an electronic device status icon and/or an area showing an electronic device virtual function key icon.
In another embodiment, the abrupt change region and the standard region are relatively variable. For example, if the screen can be bent, the posture of the screen can be acquired, when the screen is bent, a first preset area in the display area is determined as a steep change area, and other areas except the steep change area are determined as standard areas; when the screen is unfolded, a second preset area in the display area is determined as a steep change area, and other areas except the steep change area are determined as standard areas.
The first preset area is different from the second preset area. For example, if the screen is a flexible screen, the display area corresponding to the flexible screen may be divided into a first display area and a second display area along the bending line, and the second display area and the first display area can rotate relative to each other, so that the flexible screen is at different bending angles.
Based on this, when the screen is folded, it can be considered that the user tries to enable only one of the first display region and the second display region to show the image information. For example, assuming that the first display region is attempted to be activated, the first preset region may include one or more regions among a status display region located within the first display region and a connection region between the first display region and the second display region.
The second preset region may include a second display region and a status display region located within the first display region; or a second display region and a connection region between the first display region and the second display region; still alternatively, a second display area, a status display area located within the first display area, and a connection area located between the first display area and the second display area are included. The state display area can display states of electric quantity, network information, operator, alarm clock condition and the like of the electronic equipment.
It should be noted that: here, the first display area is only used as an example when the screen is folded. In other embodiments, the user may also activate the second display area, and the first predetermined area may include a status display area located in the second display area.
In step 102, the brightness of the abrupt change region and/or the standard region is adjusted to reduce the brightness difference between the abrupt change region and the standard region.
In this embodiment, the screen may include an OLED screen, and the screen may include an OLED (Organic Light-Emitting Diode) screen, and specifically may be an AMOLED (Active-Matrix Organic Light-Emitting Diode or Active-Matrix Organic Light-Emitting Diode) or a PMOLED (Passive-Matrix Organic Light-Emitting Diode), which is not limited by the disclosure.
In one embodiment, the brightness value of each sub-pixel in the abrupt change region may be adjusted to be within a first predetermined brightness range, and the difference between each brightness value in the first predetermined brightness range and the brightness value of the standard region is smaller than a first predetermined threshold. For example, the brightness value of each sub-pixel in the abrupt change region may be adjusted to be the same as the brightness value of the standard region, or different by one unit brightness, or three unit brightnesses, etc., which is not limited by the present disclosure. Therefore, under the condition of the same input parameters, the screen brightness can be prevented from being too dark, and the visual perception of a user is improved.
In another embodiment, the brightness value of each sub-pixel in the standard region may be adjusted to be within a second predetermined range, and the difference between each brightness value in the second predetermined range and the brightness value of the abrupt change region is smaller than a second predetermined threshold. For example, the brightness value of each sub-pixel in the standard region may be adjusted to be the same as the brightness value of the abrupt change region, or different by one unit brightness, or three unit brightnesses, etc., which is not limited by the present disclosure. Therefore, the sub-pixels in the steep change area can be prevented from bearing extreme load, the service life of the sub-pixels in the steep change area can be prolonged, and the service life of a screen can be prolonged.
In yet another embodiment, the brightness value of the standard region and the brightness value of the abrupt change region may be adjusted to be within a third preset brightness range, each brightness value within the third preset brightness range being less than the brightness value of the standard region and greater than the brightness value of the abrupt change region. For example, the brightness values of the standard region and the abrupt change region may be adjusted to the average brightness of the two, or may be different from the average brightness by one unit brightness, or three unit brightness, etc., which is not limited by the present disclosure. Therefore, the balance between the screen brightness and the load born by the pixels in the steep change area can be realized, the screen brightness is ensured, and the service life is relatively prolonged.
In yet another embodiment, the brightness of the critical region may be adjusted. One part of the critical region is located in the standard region and the other part is located in the abrupt change region. And the brightness of the critical area is gradually changed from one side close to the standard area to one side close to the steep-changing area, so that the brightness between the steep-changing area and the standard area is well connected, the brightness is prevented from changing steeply, and the brightness is buffered visually.
It can be known from the above embodiments that, in the present disclosure, by adjusting the brightness of the standard region and/or the abrupt change region, the brightness difference between the standard region and the abrupt change region can be reduced, so that the brightness of each part of the screen is as uniform as possible, and the sudden change of brightness in the display region of the screen is avoided, which causes visual impact.
The technical scheme of the disclosure is explained in detail. The following description will be made in detail by taking a terminal as a mobile phone.
Fig. 2 is a flowchart illustrating another screen brightness adjustment method according to an exemplary embodiment. Fig. 3 is a schematic structural diagram of an electronic device 100 according to an exemplary embodiment. The electronic device 100 may be a mobile phone that may include a processor that may be used to perform the steps of the method described in fig. 2. In particular, the method may comprise the steps of:
in step 201, the pose of the screen on the electronic device 100 is acquired.
In this embodiment, as shown in fig. 3, the electronic device 100 may include a screen 101 and a device frame 102, and the device frame 102 may wrap edges of the screen 101 in the x-axis and y-axis directions to assemble and fix the screen 101.
The screen 101 may be an OLED flexible screen, so that the screen 101 may be bent. For example, the electronic device 100 may divide the display area corresponding to the screen 101 into a first display area 1A and a second display area 1B along an axis L, and the screen 101 may be bent around the axis L; here, assuming that the target bending direction of the screen 101 is a negative direction of the z-axis in fig. 1 (i.e., a direction pointing from the panel side to the back panel side of the electronic apparatus 1, that is, a direction from top to bottom), the screen 101 may be bent along the target bending direction until a double-folded state is formed as shown in fig. 4, so that the first display region 1A and the second display region 1B are arranged in a stacked manner in the z-axis direction. Of course, in some other embodiments, the target bending direction of the screen 101 is a positive direction of the z-axis in fig. 1 (i.e. a direction from the back panel side to the panel side of the electronic device 1, i.e. a direction from bottom to top), and the screen 101 can be bent along the target bending direction until the double-folded state shown in fig. 5 is formed.
In the embodiment shown in fig. 1, the axis L may be a perpendicular bisector of a long side of the screen 101 in the y-axis direction (an edge in the x-axis direction is a short side), which may reduce the size of the electronic apparatus 1 in the y-axis direction to a half of the unfolded state in fig. 3; of course, the axis L and the screen 101 may have other relationships, and the disclosure is not limited thereto. The folding angle of the screen 101 may also be less than 180 °, for example, the first display region 1A may be rotated by an angle of 60 °, 90 °, etc. along the L-axis, and the present disclosure is not limited thereto.
In step 202, it is determined that the screen is in a bent state.
In step 203, the status display area within the first display area is determined to be a steep area.
In the present embodiment, when the electronic apparatus 100 is in the state shown in fig. 4 and the first display area 1A and the second display area 1B are deviated from each other, it is determined that the screen 101 is in the bent state. Also, since the user cannot view the image information shown by the first display region 1 and the second display region 2 at the same time from the same angle, it can be considered that the user tries to enable the first display region 1A or the second display region 1B for showing the image information.
Further, the display area facing the face of the user can be determined by cooperation between electronic elements such as a gyroscope and a sensor provided inside the electronic apparatus 100. For example, assume that the first display region 1A faces the user's face after the screen 101 is folded as in fig. 4, so that it can be considered that the user attempts to activate the first display region 1A, and thus the status display region within the first display region 1A can be determined as a steep region of brightness. Similarly, when the second display region 1B is oriented toward the face of the user, it may be considered that the user attempts to activate the second display region 1B, and thus the status display region within the first display region 1B may be determined as a steep region of brightness.
Of course, when the screen 101 is bent in the positive Z-axis direction shown in fig. 3, the first display area 1A and the second display area 1B are gradually brought close to each other, and eventually the electronic apparatus 100 may be in the state shown in fig. 5. At this time, it may be considered that the user tries to switch the electronic device 100 to the standby state, and the steps of the method of the present disclosure are not started.
In step 204, it is determined that the screen is in the expanded state.
In step 205, the status display area and the second display area within the first display area are determined to be abrupt change areas.
In the present embodiment, when the mobile phone is in the state shown in fig. 3 and the first display region 1A and the second display region 1B are substantially in the same plane, it is determined that the screen 101 is in the expanded state, and further it can be considered that the user attempts to enable the first display region 1A and the second display region 1B to be used together for showing the image information.
For example, it can be assumed that the first display region 1A is used as a main screen of the electronic device 100, and the second display region 1B is used as a sub-screen of the electronic device, so that the second display region 1B is used less frequently than the first display region 1A. Therefore, the state display region within the first display region 1A and the entire second display region 1B can be determined as the steep change region.
Of course, in some other embodiments, the first display area 1A may be used as a secondary screen, and the second display area 1B may be used as a primary screen, which is not described herein again.
In step 206, the brightness of the standard area is adjusted.
In the present embodiment, for example, as shown in fig. 6, a luminance relationship curve of a steep change region a and a standard region B is shown. Wherein the brightness of the abrupt change region a is lower than that of the standard region B. Based on this, the input current can be adjusted so that the brightness of the sub-pixels in the standard area B is properly reduced until it is the same as the brightness of the abrupt change area a or the brightness difference is not greater than the preset threshold. For example, the brightness of the standard region B may be adjusted as shown by a dotted line L1 in fig. 6. The preset threshold may include one unit brightness, or three unit brightness, etc., which is not limited by the present disclosure.
Alternatively, in other embodiments, as shown in FIG. 7, another intensity relationship between the steep change region A and the standard region B is shown. Wherein the brightness of the abrupt change region a is lower than that of the standard region B. Based on this, the brightness of the sub-pixels in the abrupt change region a can be properly increased, the brightness difference from the standard region B can be reduced, or the brightness difference can be made zero by adjusting the input current. For example, the brightness of the abrupt change region a may be adjusted as shown by a dotted line L2 in fig. 7.
In yet another embodiment, as shown in fig. 8 for example, another brightness relationship between the steep change region a and the standard region B is shown, wherein the brightness of the steep change region a is lower than that of the standard region B. Based on this, the input current may be adjusted such that the luminance curve of the abrupt change region a is adjusted as shown by a broken line L3 in fig. 8 and the luminance curve of the standard region B is adjusted as shown by a broken line L4 in fig. 8, reducing the luminance difference therebetween.
In another embodiment, as shown for example in fig. 9, another brightness relationship curve of the abrupt change region a and the standard region B is shown, wherein the brightness of the abrupt change region a is lower than that of the standard region B, based on which the brightness of the critical region C between the abrupt change region a and the standard region B, one part of which is located on the abrupt change region a and the other part is located on the standard region C, can be adjusted. And, the brightness of the critical region C is graded from the direction close to the standard region B to the direction close to the abrupt change region a, thereby alleviating the abrupt change in brightness between the abrupt change region a and the standard region B.
Wherein the brightness of the standard region B is higher than that of the abrupt change region a as shown in fig. 9, so that the brightness of the critical region C decreases from the standard region B to the abrupt change region a, as shown by a dotted line L5 in fig. 9; of course, if the brightness of the standard region B is lower than that of the abrupt change region a, the brightness of the critical region C may be adjusted such that the brightness of the critical region C increases in a direction from the standard region B to the abrupt change region a, which is not limited herein. The brightness gradient of the critical region C may be a linear gradient or an arc gradient, and the disclosure is not limited thereto.
In another embodiment, for example, as shown in fig. 10, when a plurality of abrupt change regions are included in the display area, such as abrupt change region a and abrupt change region D shown in fig. 10, and the brightness of abrupt change region a is greater than that of standard region B, and the brightness of abrupt change region D is less than that of standard region B, the brightness of abrupt change region a may be adjusted to be decreased to obtain a brightness curve as shown by dashed line L6 in fig. 10; the brightness of the abrupt change region D is adjusted to increase to obtain a brightness curve as shown by a dotted line L7 in fig. 10.
It should be noted that: when a plurality of abrupt change regions are included in the display area, in addition to the adjustment method shown in the embodiment of fig. 10, one or more combinations of the manners shown in the embodiments of fig. 6 to 9 may be adopted, and are not limited herein.
