In the drawings, like reference numbers can indicate functionally identical or similar elements. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.
Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.
Referring to fig. 1, fig. 1 is a flowchart illustrating a brightness adjustment method according to an embodiment of the disclosure.
The method is applied to a display panel, and as shown in FIG. 1, the method comprises the following steps:
step S11, determining at least one brightness adjustment value according to the current brightness value of the display panel and a preset incidence relation, wherein the preset incidence relation comprises incidence relations between a plurality of brightness value intervals and a plurality of brightness adjustment values, and the brightness adjustment values corresponding to the brightness value intervals are different;
step S12, gradually adjusting the display brightness of the display panel according to the at least one brightness adjustment value until the brightness value of the display panel reaches a target brightness value.
The display brightness adjusting method and the display device can determine at least one brightness adjusting value according to the current brightness value of the display panel and the preset incidence relation, and gradually adjust the display brightness of the display panel according to the at least one brightness adjusting value until the brightness value of the display panel reaches the target brightness value, so that when the environment view changes, the display brightness is adjusted, the screen brightness is prevented from changing violently, the environment adaptability and flexibility are improved, and the user experience is improved.
In one possible embodiment, the adjustment of the screen brightness may include the following manner: after obtaining the difference value between the initial brightness and the target brightness, uniformly dividing the difference value into n parts, wherein n is a positive integer, so as to reach the target brightness after n times of brightness adjustment; and mode B: a default brightness interval k is configured, one k at a time, until the target brightness is reached, k being an integer. However, both the method a and the method B are not flexible enough, and especially when the difference is large, if the method a is adopted, the brightness variation amount of each time is large, and screen flicker is likely to occur; however, if the method B is adopted, too many times of adjustment are required, which consumes too much time. In addition, neither of the above two methods considers the difference in brightness change perception of human eyes at different screen brightness.
Compared with the related art, the mode A, the mode B and the manual adjustment mode, the display brightness adjusting method has the more flexible characteristic, can adapt to various scenes with changed ambient light, such as changing from bright to dark, changing from dark to bright and the like.
In one possible embodiment, the display panel may include at least one of a liquid crystal display panel, an organic light emitting diode display panel, a quantum dot light emitting diode display panel, a mini light emitting diode display panel, a micro light emitting diode display panel, and the like.
Embodiments of the present disclosure may be performed by processing components, including, but not limited to, a single chip, or discrete components, or a combination of chips and discrete components. The processor may be implemented in any suitable manner, for example, a microprocessor, a Central Processing Unit (CPU), a control logic portion in a memory controller, and the like may be employed, and the processing component may execute each step of the method to gradually adjust the display brightness, so as to avoid a drastic change in the display brightness, so that human eyes may have better visual experience in the process of automatically adjusting the brightness of the display screen on the display panel.
In one example, the target brightness value may be a certain brightness value or may be any value in a range.
In a possible embodiment, the preset correlation is determined according to a correspondence between a perceived brightness of human eyes and an actual display brightness.
Referring to fig. 2, fig. 2 is a schematic diagram illustrating a correspondence relationship between the perceived brightness of human eyes and the actual display brightness according to an embodiment of the disclosure.
In one example, as shown in fig. 2, the correspondence relationship between the perceived brightness of the human eye and the actual display brightness may be a gamma (gamma) curve, which may be a standard 1/2.2 gamma curve, with the abscissa being the actual display brightness and the ordinate being the perceived brightness intensity of the human eye.
In one example, as shown in FIG. 2, the human eye is more sensitive to perception of darker gray levels (lower luminance values). For example, the actual display brightness changes by only 5% from 0 to 0.05, but the human eye perceives a brightness change of about 25%.
Therefore, the embodiment of the present disclosure may determine the preset association relationship according to the gamma curve, for example, divide the abscissa of the gamma curve into a plurality of intervals, convert the intervals into a plurality of brightness value intervals (or called gray value intervals), set non-uniform and different brightness adjustment values in each brightness value interval, determine the brightness adjustment value according to the interval where the current brightness value is located, and perform adaptive adjustment on the display brightness of the display panel, so that human eyes can feel uniform brightness change in the process of automatically adjusting the brightness of the picture by the display panel.
In one example, the brightness adjustment value of the low-brightness interval is smaller than that of the high-brightness interval, that is, a smaller brightness adjustment value is set in a lower gray scale (low brightness) interval on the abscissa of the gamma curve, and a larger brightness adjustment value is set in a higher gray scale (high brightness) interval on the abscissa, so that the brightness perceived by human eyes can be uniformly changed in the process of automatically adjusting the brightness of the picture by the display.
In one example, the interval length of the luminance value interval of low luminance is smaller than the interval length of the luminance value interval of high luminance.
For example, as shown in fig. 2, the full scale 1 is equally divided into four parts, such as 0 to 0.25, 0.25 to 0.5, 0.5 to 0.75, and 0.75 to 1, according to the ordinate, i.e. the perceived brightness of human eyes, and then the four parts of the equally divided intervals of the ordinate are mapped on the abscissa to obtain a plurality of abscissa intervals: 0 to 0.05, 0.05 to 0.22, 0.22 to 0.54, 0.54 to 1, and converting 4 abscissa intervals into four brightness value intervals according to a standard color level of 0 to 255: 0 to 13, 13 to 56, 56 to 138, 138 to 255, it can be seen that the interval length of the low-brightness interval is smaller than the interval length of the high-brightness interval.
In a possible embodiment, the step S11 of determining at least one brightness adjustment value according to the current brightness value of the display panel and the preset association relationship may include:
and determining at least one brightness adjusting value according to the brightness value interval to which the current brightness value belongs.
In a possible embodiment, the step S11 of determining at least one brightness adjustment value according to the current brightness value of the display panel and the preset association relationship may include:
and determining a plurality of corresponding brightness adjustment values according to a plurality of brightness value intervals to which the brightness values between the current brightness value and the target brightness value belong.
In one example, the brightness adjustment value may be determined according to the following:
wherein, k1 to kn correspond to n different brightness value intervals from dark to light respectively (brightness value is increased gradually), δ D (D1 to dn) is the absolute value of brightness adjustment value of n different brightness value intervals from k1 to kn respectively, DINMay be the current luminance value of the input.
In one example, the brightness adjustment value may change with the change of the brightness value interval from dark to light, for example, as the brightness value interval changes from dark to light, the brightness adjustment value corresponding to the brightness value interval gradually becomes larger, and the gradually larger manner may be gradually increasing, proportionally larger, and the like.
Let four luminance value intervals k1, k2, k3, k4 be: 0 to 13, 13 to 56, 56 to 138, 138 to 255, and the absolute values of the brightness adjustment values corresponding to the four brightness value ranges k1, k2, k3, and k4 are respectively: if d1 is 2, d2 is 4, d3 is 8, and d4 is 12, then the embodiment of the present disclosure may determine a corresponding luminance adjustment value according to the luminance value interval in which the current luminance value is located, for example, if the current luminance value is in the luminance value interval k1, the absolute value of the luminance adjustment value may be d1 is 2, and the luminance adjustment value may be positive or negative, that is, when adjusting from the current luminance value to the target luminance value, the luminance adjustment value has a different sign based on the difference of the adjustment direction, and if the target luminance value is greater than the current luminance value, the adjustment direction may be determined as upward adjustment (gradually increasing luminance), and the luminance adjustment value is a positive value (e.g., d1 is 2); assuming that the target luminance value is smaller than the current luminance value, it may be determined that the adjustment direction is downward adjustment (gradually decreasing luminance), and the luminance adjustment value is negative (e.g., d1 — 2).
The embodiment of the present disclosure may successively determine the brightness adjustment value, that is, determine at least one brightness adjustment value according to the brightness value interval to which the current brightness value belongs, or directly determine a plurality of required brightness adjustment values, that is, determine a plurality of corresponding brightness adjustment values according to a plurality of brightness value intervals to which the brightness value between the current brightness value and the target brightness value belongs, so as to adjust the display brightness of the display panel.
In a possible implementation, the step S12 of gradually adjusting the display brightness of the display panel according to the at least one brightness adjustment value until the brightness value of the display panel reaches the target brightness value may include:
determining an adjusting direction according to the current brightness value and the target brightness value;
and gradually adjusting the display brightness of the display panel according to the determined adjusting direction and the brightness adjusting value until the brightness value of the display panel reaches a target brightness value.
In one example, by determining the direction of adjustment, the sign of the brightness adjustment value may be determined, thereby determining whether the brightness adjustment is a highlight adjustment or a dim adjustment.
In a possible implementation manner, the adjusting the display brightness of the display panel according to the determined adjustment direction and brightness adjustment value may include:
if the current brightness value is smaller than the target brightness value, the brightness value of the display panel is adjusted by using the sum of the current brightness value and the brightness adjustment value and the smaller of the target brightness value; or
If the current brightness value is larger than the target brightness value, the brightness value of the display panel is adjusted by using the sum of the current brightness value and the brightness adjustment value and the larger of the target brightness value.
In one example, the summation of the current luminance value and the luminance adjustment value may be implemented using an addition circuit (e.g., including an adder).
In one example, if the current brightness value is smaller than the target brightness value, the brightness adjustment direction is brightness enhancement adjustment, on one hand, the brightness adjustment value is a positive value, and the sum of the current brightness value and the brightness adjustment value is larger than the current brightness value, and on the other hand, the brightness value of the display panel is adjusted by using the smaller of the sum of the current brightness value and the brightness adjustment value and the target brightness value (i.e., the sum of the current brightness value and the brightness adjustment value), so that the display brightness tends to the target brightness value.
In one example, if the current brightness value is greater than the target brightness value, the brightness adjustment direction is a dimming adjustment, on one hand, the brightness adjustment value is a negative value, and the sum of the current brightness value and the brightness adjustment value is smaller than the current brightness value, and on the other hand, the brightness value of the display panel is adjusted by using the sum of the current brightness value and the brightness adjustment value and the smaller of the target brightness value (i.e., the sum of the current brightness value and the brightness adjustment value), so that the display brightness tends to the target brightness value.

In one example, the direction is adjusted as shown in FIG. 5The determining unit 210 may determine the initial brightness value D according to the display panelSTART(current brightness value of display panel at the time of ambient light change) and target brightness value DTARGETDetermines the adjustment direction DIR. Assume a target luminance value DTARGETGreater than the current brightness value (i.e. the starting brightness value D)START) Then, it may be determined that the adjustment direction is upward adjustment (gradually increasing the brightness), and the adjustment direction may be a third state (e.g., high level); assume a target luminance value DTARGETLess than the current brightness value, the adjustment direction may be determined to be a downward adjustment (gradually decreasing brightness), and the adjustment direction may be a fourth state (e.g., low level).
