Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The method for preventing the splash screen according to the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

In practice, when an electronic device is charged, the VPH _ PWR port of the charging chip is connected to each load terminal as a system Power supply, and the load includes, for example and without limitation, a Power Amplifier (PA), a speaker Power Amplifier, and an AMOLED Power driver. During the charging process of the electronic device, the VPH _ PWR port is caused to be very close to the ELVDD port voltage of the AMOLED power supply driver, that is, the VPH _ PWR port voltage is increased to cause the ELVDD port voltage to be increased, and the screen brightness of the electronic device is low to cause the ELVDD port current to be small, that is, the charging energy of the VPH _ PWR port is large, and the discharging energy of the ELVDD port is small, which easily causes the imbalance between the charging energy and the discharging energy of the AMOLED power supply driver. To solve this problem, the AMOLED driving power is usually controlled to enter PSM, and then the ELVDD port voltage drops, however, the ELVDD port voltage jitter may cause a screen flicker. Compared with the prior art, the method and the device have the advantages that under the condition that the electronic equipment is in the charging state and the screen brightness of the electronic equipment is lower than the set threshold value, the ELVDD port current is increased by increasing the brightness of at least part of pixel points of the display interface of the electronic equipment, the balance of the charging energy and the amplification energy of the AMOLED driving power supply is achieved, the AMOLED driving power supply does not enter the PSM mode, and the screen flicker problem is avoided.

The embodiment of the application provides a method for preventing screen flashing, an execution main body of the method can be electronic equipment, and the electronic equipment can be any equipment with a display screen, such as a mobile phone, a tablet personal computer and the like, and is not limited herein. The following embodiments will be described with the execution main body as an electronic apparatus.

As shown in fig. 1, the method for preventing the splash screen includes the following steps S2100 to S2200:

s2100, when the electronic device is in a charging state and the screen brightness of the electronic device is lower than a first set threshold, obtaining at least some pixel points of a display interface of the electronic device.

The first set threshold may be a value set according to a specific application scenario and a specific application requirement, and when the electronic device is in a charging state and the screen brightness of the electronic device is lower than the first set threshold, the ELVDD port current may be smaller, for example, the ELVDD port current is 10mA, and the VPH _ PWR port voltage is larger, which may cause a problem of screen flicker.

In this embodiment, two different methods are used to obtain at least part of the pixel points of the display interface of the electronic device for the solid interface and the non-solid interface.

In an example, when the display interface of the electronic device is a non-solid interface, the acquiring at least a part of the pixel points of the display interface of the electronic device in S2100 may further include the following S2110 to S2150:

s2110, acquiring an initial gray-scale value of each pixel point in the display interface.

In this embodiment, due to the interface distribution of the solid interface and the non-solid interface, different manners of obtaining at least part of the pixel points are respectively given for the display interface being the solid interface and the non-solid interface.

The gray scale is the brightness change between the brightest and darkest, and is divided into a plurality of parts so as to facilitate the control of the screen brightness corresponding to the signal input. Each digital picture is composed of a number of dots, also called pixels (x, y), where x represents the number of columns of pixels and y represents the number of rows of pixels. The gray scale value is a value representing the degree of darkness and lightness of the pixel point, that is, the gray scale value represents the gradation level of different lightness between the darkest and the brightest of the pixel point.

Illustratively, for example, the initial gray scale value of the pixel point (1,1) in the display interface is 1, the initial gray scale value of the pixel point (1,2) is 64, the initial gray scale value of the pixel point (1,6) is 64, the initial gray scale value of the pixel point (1,3) is 56, the initial gray scale value of the pixel point (1,9) is 56, and the initial gray scale value of the pixel point (2,7) is 56, of course, other pixel points are also included in the display interface, which is not described in detail herein.

And S2120, grouping all the pixel points according to the initial gray-scale value to obtain a plurality of pixel groups.

All the pixels in any pixel group have the same initial gray-scale value.

Continuing with the above example, the pixel point (1,1) is a pixel group called as the first pixel group, the initial gray-scale values of the pixel point (1,2) and the pixel point (1,6) are both 64, the two pixel points form the second pixel group, the initial gray-scale values of the pixel point (1,3), the pixel point (1,9) and the pixel point (2,7) are both 56, the three pixel points form the third pixel group, of course, the fourth pixel group, the fifth pixel group, the nth pixel group, and the like may also be included, where n is an integer greater than 1.

S2130, an area value of each pixel group is obtained.

Continuing with the above example, the area value is the number of pixels included in the pixel group, for example, the area value of the first pixel group may be 1, the area value of the second pixel group may be 2, and the area value of the third pixel group may be 3.

S2140, obtaining a target pixel group according to the area value.

In this embodiment, the obtaining of the target pixel group in S2140 according to the area value may further include the following S2141 to S2142:

s2141, sorting the area values to obtain a sorting result.

Continuing with the above example, the area value 1 of the first pixel group, the area value 2 of the second pixel group, the area value 3 of the third pixel group and the area value of the nth pixel group may be sorted from small to large to obtain a sorting result, as shown in table 1 below:

TABLE 1 results of ranking

The area rank is from small to large	Containing pixel point coordinates	Initial gray scale value
			1	1,1	1
2	1,2、1,6	64
			3	1,3、1,9、2,7	56
…	…	…

S2142, according to the sorting result, obtaining the pixel groups corresponding to the area values of the previous preset number as the target pixel group.

The predetermined number may be a numerical value set according to a specific application scenario and specific requirements, and for example, the predetermined number may be 10.

Continuing with the above example, the pixel group corresponding to the area value of the top 10 of the sequence may be selected as the target pixel group.

S2150, acquiring all the pixels included in the target pixel group as at least a part of the pixels.

In one example, all the pixels included in the target pixel group may be directly obtained as at least some of the pixels. For example, the pixel points included in the pixel group corresponding to the area value of the top 10 in the above table 1 are selected as at least part of the pixel points, and fig. 2 shows 2 pixel points selected from the display interface, where circle 1 represents pixel point (1,2), circle 2 represents pixel point (1,6), and the initial gray scale values of the two pixel points are both 64.

In an example, for example, all the pixels included in the target pixel group may be used as at least part of the pixels only when the initial gray-scale values of all the pixels in the target pixel group are greater than the second set threshold. The second set threshold may be a value set according to a specific application scenario and a specific requirement, and the second set threshold may be 10. For example, after selecting the pixel group corresponding to the area value of 10 before ranking in the above table 1 as the target pixel point, it is further determined whether the initial gray scale value of each pixel point in the target pixel group is greater than 10, and only when the initial gray scale value is greater than 10, the corresponding pixel point is taken as at least part of the pixel points.

In an example, when the display interface of the electronic device is a solid interface, the acquiring at least a part of the pixel points of the display interface of the electronic device in S2100 may further include S2111: and acquiring at least part of pixel points from the display interface by taking the central point position of the display interface as a starting point or an end point for acquiring.

In this embodiment, for the solid interface, the middle brightness is actually the largest and the peripheral brightness is decreasing in order due to the screen distribution. Here, as shown in fig. 3, the pixel points within the circle with the center point of the interface as the radius may be selected as at least part of the pixel points, for example, the pixel points within the radius circles 1 and 2 may be selected as at least part of the pixel points; alternatively, as shown in fig. 4, the surrounding pixels may be selected as at least part of the pixels, for example, the pixels in the surrounding 1 and 2 may be selected as at least part of the pixels.

S2200, increasing the gray scale value of each pixel point in at least some pixel points.

In this embodiment, the current of the ELVDD port can be increased by increasing the gray scale values of at least some of the pixels.

In this embodiment, the increasing the gray level value of each of at least some of the pixels in S2200 may further include the following steps S2210 to S2230:

s2210, obtaining an initial gray scale value of each pixel point.

Illustratively, at least some of the pixels may be selected according to the above S2110 to S2150, and for example, the pixels (1,1), the pixels (1,2), the pixels (1,6), the pixels (1,3), the pixels (1,9), and the pixels (2,7) shown in table 1 may be the pixels (1,2), and the pixels (1,6) shown in fig. 2.

Exemplarily, at least part of the pixels may also be pixels selected in S2111, for example, the pixels in

circles

1 and 2 shown in fig. 3, or the pixels in the

peripheries

1 and 2 shown in fig. 4.

S2220, the gray scale value increase rate of the pixel point is obtained.

The gray scale value increase ratio may be a numerical value set according to a specific application scenario and a specific requirement, for example, the gray scale value increase ratio may be 10%, each pixel may have the same gray scale value increase ratio, or respective corresponding gray scale value increase ratios may be set for corresponding pixels, where the gray scale value increase ratios set for each pixel may be the same or different, and are not limited herein.

S2230, on the basis of the initial gray value, increasing the gray value of the pixel point according to the gray value increasing rate.

Exemplarily, taking at least part of the pixel points included in the display interface shown in table 1 as an example, when the gray level value of each pixel point in the pixel group corresponding to the area value of the top 10 in the sequence in table 1 is greater than 10, the initial gray level value of the pixel point is increased by 10%, and after modification, the gray level value may be as shown in table 2:

TABLE 2 Gray-scale modification Table

The area rank is from small to large	Containing pixel point coordinates	Initial gray scale value	After the gray scale value is modified
				1	1,1	1	1
2	1,2、1,6	64	70
				3	1,3、1,9、2,7	56	62
…	…	…

For example, in the interface on the left side of fig. 2, circle 1 may represent pixel point (1,2), circle 2 may represent pixel point (1,6), the initial gray scale values of the two pixel points are both 64, and the modified gray scale values are both 70, so as to obtain the interface shown on the right side of fig. 2.

Exemplarily, at least a part of the pixel points selected from the display interface shown on the left side of fig. 3 include the pixel points in the

circles

1 and 2, and the gray-scale values of the pixel points in the

circles

1 and 2 may be increased to obtain the display interface shown on the right side of fig. 3.

sides

1 and 2, and the gray scale values of the pixel points in the four

sides

1 and 2 may be increased to obtain the display interface shown on the right side of fig. 4.
