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 pre-ignition area located within a display area is determined.
In this embodiment, the display area is an area to be provided with a display function, in which the pixel points are disposed in the screen. The pre-lighting area may include the entire display area or may be any portion of the display area.
In one embodiment, the display area may be divided by a middle portion of the entire display area, and the pre-lighting area may be determined as an upper half display area or a lower half display area of the entire display area according to a user operation.
In another embodiment, the area for displaying the time and the date in the display area may be determined as a pre-lighting area according to a user operation, which is not limited by the present disclosure.
In a further embodiment, the display area may include a first display area and a second display area, and the second display area and the first display area may be relatively rotatable to change the posture of the screen. Therefore, by acquiring the posture of the screen, if the screen is determined to be bent, the first display area or the second display area can be determined as the pre-lighting area; if it is determined that the screen is unfolded, both the first display area and the second display area may be determined as the pre-lighting area.
Where the screen is unfolded it is understood that the first display area and the second display area are substantially in the same plane with an angle of 180 between them, or very close to 180, for example the angle may be any angle in the range 180 + -5. The screen bend may be understood as an included angle between the first display area and the second display area, for example, 60 ° or 0 °, specifically, any other angle besides 180 ° ± 5 °, which is not limited by the present disclosure.
In step 102, a brightness value interval corresponding to a pixel point in the pre-lighting area is determined according to a mapping relation between the pixel point and the brightness value in the display area, wherein the brightness value of each pixel point in the display area is related to the distance from the pixel point to the screen IC component.
In this embodiment, the mapping relationship between the pixel points and the brightness values in the display area may be determined according to a predetermined test or an experiment, that is, the brightness value corresponding to each pixel point is determined. In the present application, the brightness value of each pixel is related to the distance between the pixel and the screen IC device. The screen IC component is electrically connected with a lead wire led out from each pixel point and used for controlling the current input to each pixel point, so that each pixel point can switch the on-off state or adjust the brightness.
It can be understood that the specification of the screen IC assembly is usually smaller than the specification of the display area, and in order to avoid shielding the light generated by the pixel points, the screen IC assembly is usually located at the edge of the display area, which also results in the distance from each pixel point to the screen IC assembly, i.e. the lengths of the leads between each pixel point and the screen IC assembly are different, and since the lengths of the leads are positively correlated with the line loss or impedance caused by the leads, even if the screen IC assembly controls to input the same current to each pixel point, the luminance value of each pixel point still can be caused to be different. For example, it may be that the farther away from the screen IC component the pixel is, the lower the brightness.
Further, a brightness value interval corresponding to the pixel point in the pre-lighting area may be determined according to a mapping relationship between the pixel point and the brightness value in the display area. For example, each pixel point in the display region may be identified, so that an identifier of the pixel point in the pre-lighting region may be obtained, and a luminance value interval may be determined according to the obtained identifier of the pixel point in the pre-lighting region, that is, a mapping relationship between the pixel point and the luminance value in the pre-lighting region is obtained. The identifier may include a number of each pixel point; or, the position information used for representing the position of the pixel point may also be obtained according to the arrangement rule of the pixel points, for example, the second row and the third column; fourth row, fifth column, etc.
In step 103, a reference brightness is determined according to the brightness value in the brightness value interval, so as to adjust the brightness of the pre-lighting area according to the reference brightness.
In this embodiment, the reference luminance may be smaller than the maximum luminance corresponding to the luminance value interval and larger than the minimum luminance corresponding to the luminance value interval.
Furthermore, each brightness value in the brightness value interval has a corresponding pixel point, so that the numerical value in the brightness value interval is a discrete point and is not continuous. Therefore, all brightness values corresponding to the brightness value interval can be subjected to ascending or descending sorting to obtain a median, and the median is determined as the reference brightness; or, an average may be determined according to all the luminance values corresponding to the luminance value interval, and then the average is determined as the reference luminance; alternatively, a mode may be determined, and the mode may be determined as the reference luminance; still alternatively, the average value of the maximum luminance value and the minimum luminance value in the luminance value interval may be taken. Naturally, there may be a plurality of other calculation methods to determine the reference luminance, which are not described herein.
The reference brightness is used for adjustment, and compared with a scheme of adjusting according to the maximum brightness, the load of pixel points with brightness lower than the reference brightness can be prevented from being excessively increased, and the service life is prolonged; compared with the technical scheme of adjusting according to the minimum brightness, the method can avoid the over-low brightness of the pre-lighting area, and can make full use of each pixel point.
Further, after the reference luminance is acquired again, the luminance of the pre-lighting region may be adjusted based on the reference luminance, that is, the luminance of the pre-lighting region after being lit may be determined.
Specifically, the brightness value of each pixel point in the pre-lighting area can be adjusted to be within the preset brightness range. For example, the input current of each pixel point in the pre-lighting area may be adjusted, so as to adjust the brightness of the pixel point to be within the preset brightness range. For example, the input current can be properly increased for a pixel point with brightness lower than the reference brightness, so as to overcome the line loss and impedance caused by the lead; and the pixel point with the brightness higher than the reference brightness can properly reduce the input current to reduce the brightness.
The preset brightness range comprises a reference brightness, and the difference between any brightness value in the preset brightness range and the reference brightness is smaller than a preset threshold value. Therefore, the brightness difference between the pixel points in the pre-lighting area can be reduced, the phenomenon that a single area is too bright is avoided, and the visual experience of a user is improved.
For example, the preset luminance range may be the reference luminance ± five unit luminances, or the reference luminance ± three unit luminances, etc., which are not described in detail herein. For example, the brightness value of each pixel in the pre-lighting area may be adjusted to the reference brightness, so as to ensure the display uniformity of the pre-lighting area.
In the above embodiments, the screen may include an OLED (Organic Light-Emitting Diode) screen, and specifically may be an AMOLED (Active-matrix Organic Light-Emitting Diode, 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.
According to the embodiment, the technical scheme provided by the disclosure can adjust the brightness of the pre-lighting area in the screen according to the reference brightness, so that the defect that the brightness of the pixel points in the pre-lighting area is different due to unequal distances from the screen IC assembly can be overcome, uniform display of the pre-lighting area is facilitated, and the visual perception is improved.
In order to explain the technical solution of the present disclosure in detail, the following describes an embodiment of the present disclosure in detail by taking a terminal as a mobile phone as an example.
Fig. 2 is a flow chart illustrating another screen brightness adjustment method according to an exemplary embodiment. The adjusting method is applied to the mobile phone shown in fig. 3, and specifically includes the following steps:
in step 201, the pose of the screen on the handset 100 is obtained.
In this embodiment, as shown in fig. 3, the mobile phone 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, so as 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 mobile phone 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 the expanded state.
In step 203, the first display area 1A and the second display area 1B are determined as the pre-lighting areas.
In the present embodiment, when the mobile phone 100 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 it can further be considered that the user attempts to enable the first display region 1A and the second display region 1B to be used in common for showing image information. Therefore, both the first display area 1A and the second display area 1B can be determined as the pre-lighting area.
In step 204, it is determined that the screen is in a bent state.
In step 205, the first display area 1A is determined as the pre-lighting area.
In the present embodiment, when the mobile phone 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. Therefore, either the first display area 1A or the second display area 1B can be determined as the pre-lighting area.
Specifically, as shown in fig. 4, assuming that the screen 101 is folded with the first display region 1A facing the face of the user, it can be considered that the user attempts to activate the first display region 1A, thus determining the first display region 1 as a pre-lighting region. Specifically, the display area facing the face of the user can be determined by cooperation between electronic components such as a gyroscope and a sensor provided inside the mobile phone 100.
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 cellular phone 100 may be in the state shown in fig. 5. At this time, it may be considered that the user tries to switch the cellular phone 100 to the standby state so that neither the first display region 1A nor the second display region 1B is a pre-lighting region.
In step 206, a brightness value interval corresponding to the pre-lighting area is determined according to a mapping relationship between the pixel points and the brightness values in the display area corresponding to the screen 101.
In the present embodiment, as shown in fig. 6, the cellular phone 100 may further include a screen IC assembly 103, assuming that the screen 101 is in an unfolded state and the screen IC assembly 103 is arranged along the Y axis. Then, as shown in fig. 6, each pixel point may be arranged with a lead connected to the screen IC device 103, and the lengths of the leads between the pixel point and the screen IC device 103 are different according to the positions of the pixel points.
The longer the length of the lead between the pixel point and the screen IC module 103 is, the greater the line loss and impedance of the lead to the input current is, so that the luminance of the pixel point with the longer lead is lower than that of the pixel point with the shorter lead under the condition that the input current is equal to each other. Therefore, under the same input current, the brightness value of the pixel is inversely related to the brightness value of the pixel to the screen IC component 103.
In this embodiment, the pixels in the display area corresponding to the screen 101 may be numbered, and the numbers are not overlapped with each other. Based on this, the mapping relationship between the pixel points and the brightness values in the display area can be reflected as the mapping relationship between the serial numbers of the pixel points and the brightness values in the display area. In combination with the pre-lighting area determined in step 203 or step 205, a number corresponding to a pixel point in the pre-lighting area may be obtained, and a luminance value interval corresponding to the pixel point in the pre-lighting area may be determined according to the number corresponding to the pixel point in the pre-lighting area and a mapping relationship between the number of each pixel point in the display area and the luminance value.
It should be noted that: in the embodiment shown in fig. 6, the illustration is simplified for convenience of illustration, in practical cases, the arrangement of the leads between the pixel points and the screen IC assembly 103 may be different from that shown in fig. 6, for example, the leads of the pixel points may be led to the side edge along the X axis first, then the screen IC assembly is along the X axis, and then the leads are bent to be electrically connected with the screen IC assembly 103. Alternatively, other modes are possible, and are not described in detail herein.
In step 207, a median of the luminance values is determined from the luminance value interval.
In this embodiment, the pixel points in the pre-lighting area and the brightness values in the brightness value interval are in a one-to-one correspondence relationship. Thus, the respective luminance values may be arranged in ascending or descending order to determine the median of all the luminance values in the array.
Alternatively, in other embodiments, an average, or a mode, or an average between a maximum and a minimum may be determined, and the disclosure is not limited thereto.
In step 208, the median is determined as the reference luminance.
In the present embodiment, the median is determined as the reference luminance, so that luminance adjustment can be performed subsequently based on the reference luminance. Compared with the scheme of adjusting according to the maximum brightness, the method can avoid excessively increasing the load of the pixel points with the brightness lower than the reference brightness, and prolong the service life; compared with the technical scheme of adjusting according to the minimum brightness, the method can avoid the over-low brightness of the pre-lighting area, and can make full use of each pixel point.
In step 209, the input current of each pixel is adjusted according to the reference brightness.
In step 210, the pre-lighting area is lit and image information is displayed.
In this embodiment, the input current can be increased appropriately for the pixel point with the luminance lower than the reference luminance, so as to overcome the line loss and the impedance caused by the lead; and the pixel point with the brightness higher than the reference brightness can properly reduce the input current to reduce the brightness. After the pre-lighting area on the subsequent screen 101 is lighted, the pre-lighting area can be uniformly displayed, and the visual perception of the user is improved.
