The present application relates to the field of display technology, and particularly to a method, apparatus, device, and storage medium for driving a display screen to display.
With the continuous development of display technology, the function of the display screen is more and more diversified. For example, the display screen may be provided with a brightness adjustment control, which can adjust the brightness of the display screen by adjusting the level of brightness adjustment. Taking a brightness adjustment bar as the brightness adjustment control, and for example, the brightness adjustment bar is slid to present the same screen with different brightness.
When the brightness of the display screen is adjusted, the brightness variation of the display screen should be uniform to adapt to human eye. Nonetheless, the brightness variation of the display screen is not uniform in the related technology.
Embodiments of the present application provide a method, apparatus, device, and storage medium for driving a display screen to display, which can solve the problem that the brightness variation of the display screen is not uniform in the related technology.

In a second aspect, the embodiments of the present application provide an apparatus for driving a display screen to display, including: a first data obtaining module configured to obtain a current level of brightness adjustment of the display screen; a second data obtaining module configured to obtain, under a condition that the current level satisfies a first preset condition, an initial data voltage value and a compensation data voltage value corresponding to the current level, in which the first preset condition includes that a power voltage value corresponding to the current level is different from a power voltage value corresponding to a previous level or a next level directly adjacent to the current level, the current level is a level other than a designated level, a power voltage value corresponding to the level other than the designated level is determined according to a power voltage value corresponding to the designated level, and power voltage values corresponding to different designated levels are different; and a display driving module configured to drive the display screen to display based on the initial data voltage value and the compensation data voltage value.
In a third aspect, the embodiments of the present application provide a terminal device, including: a processor and a memory storing computer program instructions, in which the processor implements, when executing the computer program instructions, the method for driving a display screen to display of any one of the embodiments of the first aspect.
In a fourth aspect, the embodiments of the present application provide a computer-readable storage medium storing a computer program thereon, in which the computer program implements, when executed by a processor, the method for driving a display screen to display of any one of the embodiments of the first aspect.
In the method, apparatus, device, and storage medium for driving a display screen to display according to the embodiments of the present application, under a condition that the power voltage value corresponding to the current level is different from the power voltage value corresponding to the level directly adjacent to the current level, and the current level is a level other than the designated level, that is, under a condition that the current level is a level corresponding to an abrupt change of the power voltage value, the display screen is no longer driven to display based on only the initial data voltage value corresponding to the current level, the compensation data voltage value corresponding to the current level is also obtained, and the display screen is driven to display based on the initial data voltage value and the compensation data voltage value corresponding to the current level. Since the current level with the abrupt change of the power voltage value is compensated by the compensation data voltage value, it can be avoided that a brightness ratio of the display screen at the current level is suddenly negative, which cause brightness distortion in the display screen, and thus the non-uniform brightness variation of the display screen due to the abrupt change of the power voltage value can be avoided.

It should be noted that the implementations according to the embodiments of the present application can be combined with each other without contradiction.
Before the technical solutions according to the embodiments of the present application are described, the problems in the related technology are first specified to facilitate the understanding of the embodiments of the present application.
The display screen may be provided with a brightness adjustment control, which can adjust the brightness of the display screen by adjusting the level of brightness adjustment. Under the same gray scale, the target display brightness corresponding to different levels are different, and for example, the target display brightness corresponding to a high level is greater than the target display brightness corresponding to a low level. In addition, since the brightness requirements for the different levels are different, in order to reduce the power consumption of the display screen, at least a portion of the different levels may correspond to different power voltage values. The power voltage values include a low level power voltage (ELVSS) value, and the low level power voltage terminal may be electrically connected to the cathode of the light-emitting element of the display screen, so that the low level power voltage (ELVSS) value can be provided to the cathode of the light-emitting element.
In order to more adapt to human eye, the brightness variation of the display screen should be uniform. For example, if the brightness ratio (DL/L) is greater than 0 and less than a preset value, it may be considered that the brightness variation is uniform; and the preset value may be pre-determined, e.g., in accordance with the manufacturer's characteristic requirements. Herein, the brightness ratio
where Li and Li-1 represent the display brightness of the display screen at two adjacent levels, respectively, Li is the display brightness of the display screen at the previous one of the adjacent levels, and Li-1 is the display brightness of the display screen at the next one of the adjacent levels.
Nonetheless, the inventor has found that since a portion of the different levels may correspond to different power voltage values, that is, the power voltage value corresponding to some level is subject to an abrupt change relative to the power voltage value corresponding to a level which is adjacent to this level, and the power voltage value also affects the brightness of the display screen, therefore the display brightness corresponding to the level with the abrupt change of the power voltage value is also subject to an abrupt change, and in turn the brightness ratio DL/L corresponding to the level with the abrupt change is less than 0. That is, the brightness ratio corresponding to this level is negative, which is embodied as brightness reversal of the display screen at this level, resulting in that the brightness variation of the display screen is not uniform, and the user experience is affected.
In view of the above finding of the inventor, the embodiments of the present application provide a method, apparatus, device, and storage medium for driving a display screen to display, which can solve the problem that the brightness variation of the display screen is not uniform.
A method for driving a display screen to display according to the embodiments of the present application will be first described below.
As shown in
S130: driving the display screen to display based on the initial data voltage value and the compensation data voltage value.
Exemplarily, in order to ensure good display quality for the display screen, a gamma tuning may be performed for the display screen. Nonetheless, the brightness adjustment of the display screen may include a plurality of levels, and if the gamma tuning is performed at each level, the time for the gamma tuning will be long. In order to avoid that the time for the gamma tuning is too long, some of the plurality of levels may selected as the designated levels and the gamma tuning is performed only at the designated levels, so as to determine the corresponding data voltage values of the display screen at the designated levels. The initial data voltage value corresponding to a level other than the designated level may be determined according to the data voltage value corresponding to the designated level, so that the gamma tuning needs not to be performed for the display screen at the level other than the designated level, therefore the data for the gamma tuning is compressed, the time for the gamma tuning is reduced, and the manufacturing efficiency is improved.
In the present application, in order to distinguish between the designated level and a level other than the designated level, the data voltage value corresponding to the level other than the designated level is referred to as the initial data voltage value.
For example, as shown in
Exemplarily, the power voltage value corresponding to each designated level may be pre-set. For example, the power voltage values corresponding to the designated level A to the designated level I may be a to i, respectively, and the power voltage value corresponding to the level other than the designated level may be determined according to the power voltage value corresponding to the designated level. The power voltage values corresponding to different designated levels may be different.
For example, the power voltage value corresponding to the designated level B is −2.0 V, the power voltage value corresponding to the designated level C is −2.3 V, a level b1 and a level c1 are between the designated level B and the designated level C, and the power voltage values corresponding to the level b1 and the level c1 may be between −2.0 V and −2.3 V. For example, the power voltage value corresponding to the level b1 may be −2.1 V, and the power voltage value corresponding to the level c1 may be −2.2 V. Exemplarily, the initial data voltage values corresponding to the level b1 and the level c1 may be determined according to the data voltage values corresponding to the designated level B and the designated level C.
For example, the power voltage value corresponding to the level b1 and the level c1 is different from the power voltage value corresponding to the level directly adjacent to the level b1 and the level c1, under a condition that the brightness of the display screen is adjusted to the level b1 or the level c1, if the display screen is driven to display based on only the initial data voltage value corresponding to the level b1 and the level c1, since the level b1 and the level c1 are subject to an abrupt change of the power voltage value relative to the level directly adjacent to the level b1 and the level c1, as shown in
of the display screen at the level b1 and the level c1 is negative, resulting in that the brightness variation of the display screen is not uniform. In
Specifically, the horizontal axis may denote a register value corresponding to the level.
Exemplarily, the previous level or the next level directly adjacent to the current level may be the designated level or a level other than the designated level. In the method for driving a display screen to display according to the embodiments of the present application, under a condition that the power voltage value corresponding to the current level is different from the power voltage value corresponding to the level directly adjacent to the current level, and the current level is a level other than the designated level, that is, under a condition that the current level is a level corresponding to an abrupt change of the power voltage value, the display screen is no longer driven to display based on only the initial data voltage value corresponding to the current level, the compensation data voltage value corresponding to the current level is also obtained, and the display screen is driven to display based on the initial data voltage value and the compensation data voltage value corresponding to the current level. Since the current level with the abrupt change of the power voltage value is compensated by the compensation data voltage value, it can be avoided that the brightness ratio
of the display screen at the current level is negative, and thus the non-uniform brightness variation of the display screen due to the abrupt change of the power voltage value can be avoided.
In some optional embodiments, the method for driving a display screen to display according to the embodiments of the present application may further include: driving, under a condition that the current level does not satisfy the first preset condition, the display screen to display based on the initial data voltage value corresponding to the current level.
For example, if the current level is the designated level or if the current level is a level other than the designated level, but the power voltage value corresponding to the current level is the same as the power voltage value corresponding to the level directly adjacent to the current level, it may be considered that the power voltage value corresponding to the current level is not subject to an abrupt change, and the brightness corresponding to the current level will not be reversed, and in such a case, the initial data voltage value corresponding to the current level needs not to be compensated.
In some optional embodiments, it may be first determined whether the current level satisfies the first preset condition. As shown in
As described above, the power voltage value corresponding to each designated level may be pre-set, and the power voltage value corresponding to the level other than the designated level may be determined according to the power voltage value corresponding to the designated level.
For example, the power voltage value corresponding to the level other than the designated level may be determined by interpolation according to the power voltage value corresponding to the designated level. Specifically, the interpolation may include linear interpolation. Still taking the designated level B and the designated level C in
For another example, still taking
For example, the power voltage value corresponding to the level other than the designated level may be determined according to the power voltage value corresponding to the designated level, but not by interpolation. Specifically, still taking
According to embodiments of the present application, the manner for determining the power voltage value corresponding to the level other than the designated level is first determined, and then it is determined whether the current level satisfies the first preset condition by using different conditions for different manners, the accuracy of the determination can be ensured. Exemplarily, the brightness of the display screen may be adjusted in advance, for example, by successively changing the levels of the display screen from bright to dark, and the levels of which the brightness ratio
In some optional embodiments, at the current level, the compensation data voltage values corresponding to different gray scale values may be the same. For example, the bit number of the gray scale is 8 bits, and at the current level, the compensation data voltage values corresponding to the gray scales from 0 to 255 may be the same. Since different gray scale values share the same compensation data voltage value at the current level, the amount of data to be stored and the cost can be reduced; moreover, the determination of the compensation data voltage value shared by different gray scale values may be based on only a certain gray scale value, for example, the test screen may be a screen at a certain gray scale value, and thus the display screen needs not to display screens corresponding to different gray scale values, the tuning time required for determining the compensation data voltage value can be shortened.
As an optional embodiment, the compensation data voltage value corresponding to any one of the gray scale values at the current level is the same as the compensation data voltage value corresponding to a maximum gray scale value of the display screen at the current level. The gray scale value is positively correlated with the brightness, the greater the gray scale value, the greater the brightness, and thus the more obvious the corresponding negative brightness ratio. If the compensation data voltage value corresponding to the maximum gray scale value at the current level can solve the negative brightness ratio corresponding to the maximum gray scale value, theoretically, this compensation data voltage value can also solve the negative brightness ratio corresponding to other gray scale values.
Exemplarily, the maximum gray scale value may include gray scale 255.
Exemplarily, the compensation data voltage value corresponding to the current level may be determined based on only the maximum gray scale value of the display screen.
It may be understood that the memory corresponding to the display screen may only store the compensation data voltage value corresponding to the maximum gray scale value at the current level.
In some optional embodiments, in order to improve the compensation accuracy, the gray scale range of the display screen may be divided into a plurality of gray scale intervals, and at the current level, the compensation data voltage values corresponding to different gray scale values within a same gray scale interval are the same, and the compensation data voltage values corresponding to different gray scale intervals may be different. It may be understood that the memory corresponding to the display screen may store the compensation data voltage values corresponding to the various gray scale intervals at the current level.
Similarly, if the compensation data voltage value corresponding to the maximum gray scale value at the current level can solve the negative brightness ratio corresponding to the maximum gray scale value, the compensation data voltage value corresponding to any one of the gray scale intervals at the current level may be the same as the compensation data voltage value corresponding to a maximum gray scale value within this gray scale interval at the current level. Exemplarily, the compensation data voltage value corresponding to the current level may be determined based on only the maximum gray scale value within this gray scale interval. It may be understood that the memory corresponding to the display screen may only store the compensation data voltage value corresponding to the maximum gray scale value within each gray scale interval at the current level.
As described above, the gamma tuning may be performed for the display screen only at the designated level, the data voltage value corresponding to the display screen at the designated level is determined, and the initial data voltage value corresponding to the level other than the designated level may be determined according to the data voltage value corresponding to the designated level, thereby reducing the time for the gamma tuning.
In some optional embodiments, the initial data voltage value may be determined by linear interpolation according to the data voltage values corresponding to at least two designated levels. In this manner, since the data voltage value corresponding to the designated level is obtained according to the actual gamma tuning, even if no gamma tuning is performed for the display screen at the level other than the designated level, it can still be ensured that the initial data voltage value corresponding to the other level is accurate; moreover, only the data voltage value corresponding to the designated level is stored, the amount of data to be stored can be greatly reduced, and the capacity of the memory corresponding to the display screen can be reduced. The capacity of the memory is generally positively correlated with the area, that is, the area of the memory can be reduced, and the cost is reduced.
Exemplarily, under a condition that the current level satisfies the first preset condition, the designated levels may include a first designated level and a second designated level, the current level is between the first designated level and the second designated level, the data voltage values corresponding to the current level, the first designated level and the second designated level may be considered to conform to a linear relationship, and thus the initial data voltage value corresponding to the current level may be determined by linear interpolation according to the data voltage values respectively corresponding to the first designated level and the second designated level.
Since the display situations of adjacent levels are relatively close, the data voltage values corresponding to the adjacent levels may be considered to conform to a linear relationship. Exemplarily, the initial data voltage value corresponding to the other level may be determined by linear interpolation according to the data voltage values corresponding to two designated levels directly adjacent to the other level.
Exemplarily, under a condition that the current level satisfies the first preset condition, the current level is between the first designated level and the second designated level, the first designated level and the second designated level may be directly adjacent, and the initial data voltage value according to the current level may be determined according to the following equation (1):
For example, as shown in
Exemplarily, a 51 register may be used to indicate the level of brightness adjustment. The register value corresponding to the level may be stored in the form of hexadecimal, which may be converted to decimal when the initial data voltage value corresponding to the current level is calculated.
Exemplarily, the display screen may display a certain range of gray scales, and at the same level, the data voltage values corresponding to different gray scale values are different. In the above equation (1), V1, V2, and V0 denote the data voltage values under the same gray scale value. For example, taking gray scale 255 as an example, V1 is the data voltage value corresponding to gray scale 255 at the first designated level, V2 is the data voltage value corresponding to gray scale 255 at the second designated level, and V0 is the initial data voltage value according to gray scale 255 at the current level.
For example, if the current level is the level b1 and the compensation data voltage value corresponding to the current level is offset, then in S130, the display screen may be driven to display based on the sum of the initial data voltage value V0 corresponding to the current level and the compensation data voltage value offset.
Exemplarily, when the gamma tuning is performed for the display screen at any designated level, some gray scale binding points may be selected from a range of gray scales, and the gamma tuning is performed for the display screen only at the gray scale binding points to obtain the data voltage values corresponding to the various gray scale binding points. The data voltage value corresponding to a gray scale value other than the gray scale binding points may be calculated by linear interpolation according to the data voltage values corresponding to the gray scale binding points.
Exemplarily, the gray scale binding points corresponding to different designated levels may be the same.
In some optional embodiments, under a condition that the current level satisfies the first preset condition, as shown in
The second preset condition includes
In S510, taking gray scale 255 as an example, as shown in
In S520, the initial compensation value may be set empirically.
In S530, the display screen may be lighted up based on the sum of the data voltage value corresponding to the gray scale value at the current level and the initial compensation value, so as to display the test screen under the gray scale value.
Exemplarily, the display screen may include sub-pixels of a plurality of colors, and step S520 may specifically include: setting the initial compensation values respectively corresponding to the sub-pixels of each color under the gray scale value. Accordingly, the test screen under the gray scale value may include a white screen under the gray scale value. Compared with a tuning using a monochrome screen under the gray scale value, the number for lighting up the display screen can be reduced.
It may be understood that according to the preset condition, the display brightness value corresponding to the gray scale value at the previous level directly adjacent to the current level needs to be obtained. For example, if the current level is the level b1 and the designated level B is the previous level directly adjacent to the level b1, the display brightness value corresponding to the gray scale value at the designated level B is obtained.
In the manner for determining the compensation data voltage value according to the embodiments of the present application, since the display screen is actually tuned, the accuracy of the resulting compensation data voltage value can be ensured.
The display screen in the embodiments of the present application may be an Organic Light Emitting Diode (OLED) display screen.
The embodiments of the present application further provide an apparatus for driving a display screen to display. As shown in
The first data obtaining module 601 is configured to obtain a current level of brightness adjustment of the display screen.
The second data obtaining module 602 is configured to obtain, under a condition that the current level satisfies a first preset condition, an initial data voltage value and a compensation data voltage value corresponding to the current level, in which the first preset condition includes that a power voltage value corresponding to the current level is different from a power voltage value corresponding to a previous level or a next level directly adjacent to the current level, the current level is a level other than a designated level, a power voltage value corresponding to the level other than the designated level is determined according to a power voltage value corresponding to the designated level, and power voltage values corresponding to different designated levels are different.
The display driving module 603 is configured to drive the display screen to display based on the initial data voltage value and the compensation data voltage value.
In the apparatus for driving a display screen to display according to the embodiments of the present application, under a condition that the power voltage value corresponding to the current level is different from the power voltage value corresponding to the level directly adjacent to the current level, and the current level is a level other than the designated level, that is, under a condition that the current level is a level corresponding to an abrupt change of the power voltage value, the display screen is no longer driven to display based on only the initial data voltage value corresponding to the current level, the compensation data voltage value corresponding to the current level is also obtained, and the display screen is driven to display based on the initial data voltage value and the compensation data voltage value corresponding to the current level. Since the current level with the abrupt change of the power voltage value is compensated by the compensation data voltage value, it can be avoided that the brightness ratio DL/L of the display screen at the current level is negative, and thus the non-uniform brightness variation of the display screen due to the abrupt change of the power voltage value can be avoided.
In some optional embodiments, at the current level, the compensation data voltage values corresponding to different gray scale values are the same.
Optionally, the compensation data voltage value corresponding to any gray scale value at the current level is the same as the compensation data voltage value corresponding to a maximum gray scale value of the display screen at the current level.

Optionally, the compensation data voltage value corresponding to any one of the gray scale intervals at the current level is the same as the compensation data voltage value corresponding to a maximum gray scale value within the gray scale interval at the current level.

Optionally, the initial data voltage value is determined according to the following equation:
In some optional embodiments, the compensation data voltage value corresponding to at least one gray scale value at the current level is determined by: obtaining an initial data voltage value corresponding to the gray scale value at the current level; setting an initial compensation value corresponding to the gray scale value; driving, based on a data voltage value corresponding to the gray scale value at the current level and the initial compensation value, the display screen to display a test screen under the gray scale value and collecting a display brightness value of the display screen; if the collected display brightness value satisfies a second preset condition, directly determining the initial compensation value as the compensation data voltage value corresponding to the gray scale value at the current level; and if the collected display brightness value does not satisfy the second preset condition, adjusting the initial compensation value, until the display brightness value of the display screen satisfies the second preset condition based on the data voltage value corresponding to the gray scale value at the current level and the adjusted initial compensation value, and determining the adjusted initial compensation value as the compensation data voltage value corresponding to the gray scale value at the current level.
