Detailed ways

In the technical solution provided by the present disclosure, the correspondence between the preset adjustment amount and the brightness level is positively correlated. Thus, when the current brightness is high, the brightness of the display panel will change more after receiving the adjustment command, and the user can thus perceive that the brightness of the display panel has changed. When the current brightness is low, the brightness of the display panel will change less after receiving the adjustment command, and the user perceives that the brightness of the display panel has not changed excessively. Therefore, the brightness adjustment method and apparatus provided by the present disclosure can effectively improve the effect and flexibility of brightness adjustment of the display panel.

The embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

The embodiment of the present disclosure provides a brightness adjustment method which can be performed by a brightness adjustment device described later herein. Referring to FIG. 1, the brightness adjustment method may include:

Step 101: After receiving the adjustment instruction, determining a brightness adjustment trend according to the adjustment instruction;

Step 102: Acquire a current brightness of the display panel when the adjustment instruction is received;

Step 104: Determine a target brightness according to a current brightness, a target adjustment amount, and a brightness adjustment trend;

Step 105: Adjust the brightness of the display panel to the target brightness.

In summary, in a brightness adjustment method provided by an embodiment of the present disclosure, the adjustment amount is positively correlated with the brightness level in the correspondence between the adjustment amount and the brightness level. Thus, when the current brightness is high, the brightness of the display panel will change more after receiving the adjustment command, and the user can thus perceive that the brightness of the display panel has changed. When the current brightness is low, the brightness of the display panel will change less after receiving the adjustment command, and the user thus perceives that the brightness of the display panel has not changed excessively. Therefore, the brightness adjustment method according to the present disclosure effectively improves the effect and flexibility of the brightness adjustment of the display panel.

Embodiments of the present disclosure provide another brightness adjustment method that can be performed by a brightness adjustment device. In one embodiment, the brightness adjustment device may be a brightness control register, which may be located in a driver integrated circuit (English: Driver Integrated Circuit; Driver IC). Referring to FIG. 2, the brightness adjustment method may include:

Step 201: Receive an adjustment instruction.

As shown in FIG. 3, a brightness adjustment bar 01 and a slider 02 can be displayed on the display panel, and the slider 02 is located in the brightness adjustment bar 01, and the slider 02 can slide in the brightness adjustment bar 01. For example, the display panel may be: a liquid crystal display (English: Liquid Crystal Display; abbreviated as: LCD) and an active-matrix organic light emitting diode (AMOLED). The embodiment of the present disclosure does not limit this.

When the slider 02 is located at one end (such as the left end) of the brightness adjustment bar 01, the brightness of the display panel is the minimum brightness. When the slider 02 is located at the other end (such as the right end) of the brightness adjustment bar 01, the brightness of the display panel is the maximum brightness.

When the user needs to adjust the brightness of the display panel, the user can control the slider to slide in the brightness adjustment bar by operating on the display device, thereby triggering the brightness adjustment device to receive the adjustment command. In one embodiment, if the display panel is a touch display panel, the user can operate on the display device in such a manner that the user touches the display panel with a finger and slides the slider. If the display panel is a non-touch display panel, such as a non-touch display panel of the computer, the user can operate on the display device by the user controlling the mouse to slide the slider.

The slider adjusts a step in the brightness adjustment bar (one step is the minimum sliding distance of the slider in the brightness adjustment bar), and the brightness adjustment device can receive an adjustment command. The adjustment command may include: a direction in which the slider slides in the brightness adjustment bar, the adjustment instruction is used to instruct the brightness adjustment device to adjust the brightness of the display panel.

Step 202: Determine a brightness adjustment trend according to the adjustment instruction.

In one embodiment, the adjustment trend in the embodiments of the present disclosure may be elevated or decreased. For example, referring to FIG. 3, the slider is located at the rightmost side of the brightness adjustment bar, and the brightness of the display panel is the highest. The slider is located at the leftmost side of the brightness adjustment bar, and the brightness of the display panel is the lowest, and the slider slides from left to right. The characterization brightness changes from low to high. According to the received adjustment command, the direction in which the slider slides is left or right to determine whether the adjustment trend of the brightness is raised or lowered.

Step 203: Acquire a current brightness of the display panel when the adjustment instruction is received.

When the adjustment command is received in step 201, the brightness adjustment device can acquire the current brightness of the display panel at this time.

Step 204: Determine a brightness level of the current brightness according to a preset relationship between the brightness and the brightness level.

When determining the brightness level of the current brightness, the brightness adjusting device may first determine the brightness level corresponding to the current brightness according to the corresponding relationship between the preset brightness and the brightness level, and then determine the brightness level corresponding to the current brightness as the brightness level of the current brightness. .

For example, the brightness adjustment device may be pre-set with a correspondence between brightness and brightness level, and in the correspondence between the brightness and the brightness level, each brightness level may correspond to brightness within one brightness range, and any two brightness levels. The brightness corresponding to the higher brightness level is greater than the brightness corresponding to the lower brightness level. It should be noted that the corresponding relationship between the brightness and the brightness level may be set by the user, or may be set by the factory staff before the display device is shipped from the factory.

For example, the preset brightness and brightness level correspondence may include three brightness levels, which are respectively referred to as a first brightness level, a second brightness level, and a third brightness level, and in the first brightness level The brightness is higher than the brightness in the second brightness level, and the brightness in the second brightness level is higher than the brightness in the third brightness level.

It is assumed that in the correspondence between the brightness and the brightness level: the brightness in the brightness range of (240 nits, 350 nits) corresponds to the first brightness level, and the brightness in the brightness range of (36 nits, 240 nits) corresponds to the first The brightness level in the brightness range of [0 nits, 36 nits] corresponds to the third brightness level. That is, the brightness corresponding to the first brightness level is greater than 240 nits and less than or equal to 350 nits; The brightness corresponding to the two brightness levels is greater than 36 nits and less than or equal to 240 nits; the brightness corresponding to the third brightness level is greater than or equal to 0 nits and less than or equal to 36 nits.

If the current brightness is 180 nits, according to the preset relationship between the brightness and the brightness level, it can be determined that the brightness level corresponding to the current brightness (180 nits) is the second brightness level. At this time, the second brightness level can be determined as the brightness level of the current brightness (180 nits).

Further, referring to FIG. 3, the brightness adjustment bar may also be divided into three regions according to the three brightness levels. The three regions may be: a highlight region L1, a normal region L2, and a low-light region L3, wherein the highlight region L1 corresponds to the first brightness level, the normal region L2 corresponds to the second brightness level, and the low-light region L3 corresponds to the third brightness level. Brightness level. When the slider 02 is located in the highlight area L1, the brightness of the display panel is in the range of 240 to 350 nits; when the slider 02 is located in the normal area L2, the brightness of the display panel is in the range of 36 to 240 nits. Brightness; when the slider 02 is located in the low-light area L3, the brightness of the display panel is in the range of 0 to 36 nits.

It should be noted that, in the embodiment of the present disclosure, only the brightness that can be displayed by the display panel is divided into three brightness levels. In actual applications, the brightness that can be displayed by the display panel can be divided into other quantity of brightness levels (such as two The brightness level, the four brightness levels, and the like are not limited in this embodiment of the present disclosure. In addition, in the embodiment of the present disclosure, the brightness ranges corresponding to only three brightness levels are: (240 nits, 350 nits), (36 nits, 240 nits), and [0 nits, 36 nits] In practical applications, the brightness range corresponding to the three brightness levels can also be: (200 nits, 350 nits), (50 nits, 200 nits) nits and [0 nits, 50 nits The embodiment of the present disclosure does not limit this.

Step 205: Determine, according to a correspondence between the preset adjustment amount and the brightness level, a target adjustment amount corresponding to the brightness level of the current brightness.

The brightness adjustment device may be pre-set with a correspondence relationship between the adjustment amount and the brightness level, and in the correspondence relationship between the adjustment amount and the brightness level, the adjustment amount is positively correlated with the brightness level. That is, in the correspondence relationship between the adjustment amount and the brightness level, as the brightness level is increased, the adjustment amount is also increased. For example, the adjustment amount may be: a brightness change amount of the display panel when the slider shown in FIG. 3 slides one step in the brightness adjustment bar.

In one embodiment, the correspondence between the adjustment amount and the brightness level may include three brightness levels, that is, a first brightness level, a second brightness level, and a third brightness level. Correspondingly, the corresponding relationship between the adjustment amount and the brightness level may include three adjustment amounts: a first adjustment amount corresponding to the first brightness level, a second adjustment amount corresponding to the second brightness level, and a third adjustment corresponding to the third brightness level. the amount. In one embodiment, the first brightness level is higher than the second brightness level, the second brightness level is higher than the third brightness level, the first adjustment amount is greater than the second adjustment amount, and the second adjustment amount is greater than The third adjustment amount.

In one embodiment, the first adjustment amount may be 4 times the third adjustment amount, and the second adjustment amount may be 2 times the third adjustment amount. For example, the first adjustment amount may be 5.6 nits, the second adjustment amount may be 2.8 nits, and the third adjustment amount may be 1.4 nits. It is assumed that the brightness level of the current brightness is the second brightness level. In this case, when the slider is determined to slide one step in the brightness adjustment bar according to the brightness adjustment tendency, the brightness adjustment level of the current brightness corresponds to a target adjustment amount of 2.8 nits.

Step 206: Determine a target brightness according to a current brightness, a target adjustment amount, and a brightness adjustment trend.

For example, when the brightness adjustment trend is the brightness increase trend, the target brightness is equal to the sum of the current brightness and the target adjustment amount; when the brightness adjustment trend is the brightness reduction trend, the target brightness is equal to the difference between the current brightness and the target adjustment amount.

For example, suppose the current brightness is 30 nits and the target adjustment amount is 1.4 nits. If the brightness adjustment trend is the brightness reduction trend, it can be determined that the target brightness is 30 nits - 1.4 nits = 28.6 nits; if the brightness adjustment trend is the brightness increase trend, the target brightness can be determined to be 30 nits + 1.4 Nite = 31.4 nits.

Step 207: Adjust the brightness of the display panel to the target brightness.

After determining the target brightness, the brightness adjustment device can adjust the brightness of the display panel to the target brightness.

For example, referring to Fig. 4, in the coordinate system in which the slider position and the brightness are two coordinate axes, the broken line Q1 can characterize the correspondence relationship between the brightness change amount and the brightness level in the embodiment of the present disclosure. According to the fold line Q1, when the slider is located in the highlight area L1, the brightness level of the current brightness is the first brightness level, and the first brightness level corresponds to the first adjustment amount, and the brightness change amount T1 of the display panel and the first The adjustment amount is the same; when the slider is located in the normal area L2, the brightness level of the current brightness is the second brightness level, and the second brightness level corresponds to the second adjustment amount, and the brightness change amount T2 of the display panel is the same as the second adjustment amount; When the slider is located in the low-light area L3, the brightness level of the current brightness is the third brightness level, and the third brightness level corresponds to the third adjustment amount, and the brightness change amount T3 of the display panel is the same as the third adjustment amount. As described above, the first adjustment amount is 4 times the third adjustment amount, and the second adjustment amount is 2 times the third adjustment amount. Thus, as shown in FIG. 4, the luminance change amount T1 is four times the luminance change amount T3, and the luminance change amount T2 is twice the luminance change amount T3. That is, when the brightness level of the current brightness of the display panel is the first brightness level, each time the slider slides, the brightness adjusting means determines the unit adjustment amount at which the brightness of the display panel needs to be changed by 4 times. When the brightness level of the current brightness of the display panel is the second brightness level, each time the slider slides, the brightness adjusting device determines the unit adjustment amount at which the brightness of the display panel needs to be changed twice. When the brightness level of the current brightness of the display panel is the third brightness level, each time the slider slides, the brightness adjustment device determines the unit adjustment amount at which the brightness of the display panel needs to be changed by one time.

Referring to FIG. 4, in the coordinate system in which the slider position and the brightness are two coordinate axes, the broken line Q2 can characterize the correspondence relationship between the brightness change amount and the brightness level in the related art. According to the fold line Q2, it can be concluded that the adjustment amount corresponding to the brightness level of the current brightness is the fourth adjustment amount T4 regardless of the area in which the slider is located (in FIG. 4, T4 is equal to 2 times the unit adjustment amount).

It should be noted that the relationship between the first adjustment amount, the second adjustment amount, the third adjustment amount, and the fourth adjustment amount is merely an example, and they may be other relationships, for example, the first adjustment amount is 3 of the second adjustment amount. The second adjustment amount is 1.5 times the third adjustment amount and the like. This disclosure does not limit this.

When the current brightness is high, the brightness level of the current brightness is higher, and the brightness level corresponding to the current brightness is larger. After receiving the adjustment command, the brightness adjustment device can change the current brightness more, so that the brightness of the display panel becomes a target brightness that is largely different from the current brightness. Although the human eye is less sensitive to the perception of the brightness change of the display panel when the brightness of the display panel is high, the brightness adjustment device performs more brightness on the display panel after the slider slides one step in the embodiment of the present disclosure. Adjustment, therefore, the user can perceive that the brightness of the display panel has changed.

When the current brightness is low, the brightness level of the current brightness is lower, and the brightness level of the current brightness corresponds to a smaller amount of target adjustment. After receiving the adjustment command, the brightness adjustment device may change the current brightness less, thereby causing the brightness of the display panel to become a target brightness that is less different from the current brightness. Although the human eye is sensitive to the perception of the brightness change of the display panel when the brightness of the display panel is low, the brightness adjustment device adjusts the brightness of the display panel after the slider slides one step in the embodiment of the present disclosure. Therefore, the user does not perceive an excessive change in the brightness of the display panel.

In summary, in a brightness adjustment method provided by an embodiment of the present disclosure, the adjustment amount is positively correlated with the brightness level in the correspondence between the adjustment amount and the brightness level. When the current brightness is high, the brightness of the display panel will change more after receiving the adjustment command, and the user can thus perceive that the brightness of the display panel has changed. When the current brightness is low, the brightness of the display panel will change less after receiving the adjustment command, and the user thus perceives that the brightness of the display panel has not changed excessively. Therefore, the brightness adjustment method according to the present disclosure effectively improves the effect and flexibility of the brightness adjustment of the display panel.

Embodiments of the present disclosure provide a brightness adjustment device. Referring to FIG. 5, the brightness adjustment device 50 can include:

The first determining module 501 is configured to determine a brightness adjustment trend according to the adjustment instruction after receiving the adjustment instruction.

The brightness adjustment device 50 can include an acquisition module 502 for acquiring a current brightness of the display panel when the adjustment instruction is received.

The brightness adjustment device 50 may include a second determining module 503, configured to determine a target adjustment amount corresponding to the brightness level of the current brightness according to a correspondence between the preset adjustment amount and the brightness level. In the correspondence between the adjustment amount and the brightness level, the adjustment amount is positively correlated with the brightness level.

The brightness adjusting device 50 may include a third determining module 504, configured to determine a target brightness according to a current brightness, a target adjustment amount, and a brightness adjustment trend.

The brightness adjustment device 50 can include an adjustment module 505 for adjusting the brightness of the display panel to the target brightness.

In summary, in a brightness adjustment device provided by an embodiment of the present disclosure, the adjustment amount is positively correlated with the brightness level in the correspondence relationship between the adjustment amount and the brightness level. Thus, when the current brightness is high, the brightness of the display panel will change more after receiving the adjustment command, and the user can thus perceive that the brightness of the display panel has changed. When the current brightness is low, the brightness of the display panel will change less after receiving the adjustment command, and the user perceives that the brightness of the display panel has not changed excessively. Therefore, the brightness adjusting device according to an embodiment of the present disclosure effectively improves the effect and flexibility of the brightness adjustment of the display panel.

In one embodiment, the correspondence between the adjustment amount and the brightness level may include three brightness levels, that is, a first brightness level, a second brightness level, and a third brightness level. Correspondingly, the corresponding relationship between the adjustment amount and the brightness level may include three adjustment amounts: a first adjustment amount corresponding to the first brightness level, a second adjustment amount corresponding to the second brightness level, and a third adjustment corresponding to the third brightness level. the amount. The first brightness level is higher than the second brightness level, and the second brightness level is higher than the third brightness level. In one embodiment, the first adjustment amount may be 4 times the third adjustment amount, and the second adjustment amount may be 2 times the third adjustment amount.

FIG. 6 is another brightness adjustment device according to an embodiment of the present disclosure. As shown in FIG. 6, in addition to the module included in FIG. 5, the brightness adjustment device 50 may further include:

The fourth determining module 506 is configured to determine, according to a preset correspondence between the brightness and the brightness level, a brightness level corresponding to the current brightness.

In the correspondence between the brightness and the brightness level, each brightness level corresponds to brightness within one brightness range, and among any two brightness levels, the brightness corresponding to the higher brightness level is greater than the brightness corresponding to the lower brightness level.

The brightness adjusting device 50 may further include: a fifth determining module 507, configured to determine a brightness level corresponding to the current brightness as a brightness level of the current brightness.

In one embodiment, the brightness corresponding to the first brightness level is greater than 240 nits and less than or equal to 350 nits; the brightness corresponding to the second brightness level is greater than 36 nits and less than or equal to 240 nits; the third brightness level The corresponding brightness is greater than or equal to 0 nits and less than or equal to 36 nits.

In one embodiment, the brightness adjustment trend is a trend of brightness increase or brightness decrease. When the brightness adjustment trend is the brightness increase trend, the target brightness is equal to the sum of the current brightness and the target adjustment amount; when the brightness adjustment trend is the brightness reduction trend, the target brightness is equal to the difference between the current brightness and the target adjustment amount.

In summary, in a brightness adjustment device provided by an embodiment of the present disclosure, the adjustment amount is positively correlated with the brightness level in the correspondence relationship between the adjustment amount and the brightness level. Thus, when the current brightness is high, the brightness of the display panel will change more after receiving the adjustment command, and the user can thus perceive that the brightness of the display panel has changed. When the current brightness is low, the brightness of the display panel will change less after receiving the adjustment command, and the user thus perceives that the brightness of the display panel has not changed excessively. Therefore, the brightness adjusting device according to an embodiment of the present disclosure effectively improves the effect and flexibility of the brightness adjustment of the display panel.

It should be noted that the foregoing embodiments according to the present disclosure are all described by taking an example of triggering an adjustment instruction every time the slider moves. That is, if the slider is moved by two steps at a time in actual operation, the adjustment command will be triggered twice and the brightness adjustment method according to the above embodiment of the present disclosure is performed twice. However, those skilled in the art can easily conceive that the above-described multiple trigger adjustment command is combined to trigger only one adjustment command, and accordingly, multiple operations caused by multiple trigger adjustment commands are combined into one operation. The brightness adjustment method according to the present disclosure will be described below with a total of two steps of the slider being moved in actual operation. Continuing the foregoing example, referring to FIG. 4, if it is determined according to the brightness adjustment trend that the two steps of the slider sliding in the brightness adjustment bar are both in the same brightness level (for example, both in the second brightness level) and are increasing trends, then It can be determined that the target adjustment amount corresponding to the brightness level of the current brightness is 2.8x2=5.6 nit, and the target brightness is equal to the sum of the current brightness and the target adjustment amount. If it is determined according to the brightness adjustment trend that the two steps of the slider sliding in the brightness adjustment bar are not in the same brightness level (for example, one step is in the second brightness level and the other step is in the first brightness level) and is an increasing trend, Then, it can be determined that the target adjustment amount corresponding to the brightness level of the current brightness is 2.8+5.6=8.4 nit, and the target brightness is equal to the sum of the current brightness and the target adjustment amount.

In one embodiment, a brightness adjustment method in accordance with an embodiment of the present disclosure may be implemented as a computer executable instruction stored in a computer readable medium. When the computer executable instructions are run on a processing component, the processing component is caused to perform a brightness adjustment method in accordance with an embodiment of the present disclosure.
