Referring to fig. 3, in the first embodiment, the screen display control method includes the steps of:
step S10, obtaining the ambient brightness at regular time;
be provided with light sensor in the display screen, light sensor's output connection controller exports light intensity signal to the controller, and the controller is according to the current ambient brightness of received light intensity signal analysis. It is understood that the light sensor may detect the intensity of the ambient light periodically, for example, every three minutes, or may detect a certain time point, for example, two afternoon and six afternoon, and the setting of the time point should be adjusted according to seasonal changes, for example, the detection time point of six is postponed to six and a half in winter, and the detection time point of six is advanced to five and a half in winter. Of course, the set time point detection and the periodic detection may be performed simultaneously in combination.
And step S20, when the environment brightness changes, adjusting the opening degree of the dynamic expansion switch according to the environment brightness to adjust the picture brightness value of the display equipment.
The dynamic expansion switch is used for adjusting the current of the light emitting diode in the display device, the ambient brightness in the embodiment is divided into a plurality of grades, each grade corresponds to a brightness range, and the change of the ambient brightness refers to that the brightness range in which the current ambient brightness falls is changed relative to the brightness range in which the previous ambient brightness falls, for example, the brightness range in which the current ambient brightness falls is a first brightness range, the brightness range in which the previous ambient brightness falls is a second brightness range, and when the first range is inconsistent with the second range, the ambient brightness is determined to have changed. The light emitting diode mentioned in this embodiment may be an organic light emitting diode or a quantum dot light emitting diode.
After the dynamic expansion switch is turned on, a plurality of gears can be adjusted (for example, a strong gear, a medium gear and a weak gear), the current of the light-emitting diode corresponding to each gear is different, and the higher the gear is, the larger the current is. The current level here is different from the overall duty cycle of the current when the screen brightness is adjusted, and refers to the current intensity level entering the light emitting diode. In a specific implementation, the current of each led is controlled by a panel driver, a dynamic expansion switch sends a signal for adjusting a gear to the panel driver, the specific current intensity is distributed by the panel driver, when the current intensity is increased, the brightness value of the image on the display screen is increased, and when the current intensity is decreased, the brightness value of the image on the display screen is decreased, and the change of the brightness value of the image is reflected in the color change of the display image itself. And when the environment brightness is smaller than the preset reference brightness, the environment is a dark environment, and the dynamic expansion switch is closed at the moment.
In another embodiment, the display screen may also support manual adjustment by the user, and if manual adjustment of the expansion switch by the user is received when the ambient brightness value is greater than or equal to the preset reference brightness (i.e., in a bright environment), the dynamic expansion switch prioritizes the preference of the user. And if the environment brightness is changed into a second bright environment after being changed into a dark environment from a first bright environment, the dynamic expansion switch manually adjusted by the user in the first bright environment is still recovered during the second bright environment so as to give priority to the preference of the user.
In a second embodiment, as shown in fig. 4, the step of adjusting the opening degree of the dynamic expansion switch to adjust the brightness value of the picture of the display device includes:
step S21, acquiring a first picture brightness value corresponding to the environment brightness;
step S22, acquiring a second picture brightness value of the current display picture;
step S23, when the difference between the second image brightness value and the first image brightness value is greater than or equal to a first preset threshold, adjusting the dynamic expansion switch to adjust the second image brightness value to the first image brightness value.
In this embodiment, the ambient brightness is divided into a plurality of levels, each level corresponds to a brightness range, and each brightness range has a corresponding image brightness value. In a specific implementation, when there is a change in the ambient brightness, a first image brightness value corresponding to a brightness range in which the ambient brightness is located may also be obtained first, the first image brightness value is compared with a second image brightness value of the currently displayed image, and when a difference between the first image brightness value and the second image brightness value is greater than or equal to a first preset threshold, the dynamic expansion switch is adjusted to the first image brightness value.
If the current environment brightness is 30nit, the corresponding first image brightness value is 20nit, the obtained second image brightness value is 100nit, and the difference between 100nit and 20nit is 80nit, if the first preset threshold value is 10nit at this time, 80nit is greater than the first preset threshold value 10nit, and the dynamic expansion switch needs to be adjusted to enable the brightness value of the displayed image to be 20 nit. The controller can preset the corresponding relation between the brightness level and the display parameter, and the corresponding relation comprises a mapping table or a curve graph and the like, so that the adjustment of the brightness value of the picture is stable and reliable.
Based on the first example, in a third embodiment, as shown in fig. 5, before adjusting the opening degree of the dynamic expansion switch to adjust the brightness value of the picture of the display device when there is a change in the ambient brightness, the picture display control method further includes the steps of:
s31, comparing the ambient brightness with a preset reference brightness;
s32, when the ambient brightness is smaller than the preset reference brightness, closing the dynamic expansion switch;
and S33, when the environment brightness is larger than or equal to the preset reference brightness, determining whether the environment brightness has change.
The change of the ambient brightness can be firstly classified into a change of a bright and dark environment, and the environment is a bright environment when the ambient brightness value is greater than or equal to the preset reference brightness, and the environment is a dark environment when the ambient brightness value is less than the preset reference brightness. In this embodiment, the environment brightness is divided into a plurality of levels for the bright environment, that is, the dynamic expansion switch is not adjusted in the dark environment, the bright environment further determines that the environment brightness changes, and when the environment brightness changes, the image brightness value of the display device is adjusted according to the opening degree of the dynamic expansion switch adjusted by the environment brightness.
When the ambient brightness is smaller than the preset reference brightness, the environment is dark, and the dynamic expansion switch is turned off at the moment, so that the display screen can adapt to various brightness changes.
Of course, the brightness level may be set for the dark environment according to the requirement, specifically according to the environment or the user requirement.
Based on the first embodiment, as shown in fig. 6, the method for controlling screen display according to the present invention further provides a fourth embodiment, in which, when there is a change in the ambient brightness, the step of adjusting the opening degree of the dynamic expansion switch according to the ambient brightness to adjust the screen brightness value of the display device includes:
s24, comparing the ambient brightness with a preset reference brightness when the ambient brightness changes;
in this step, the change of the ambient brightness may be firstly divided into a change of a bright and dark environment, and the environment is a bright environment when the ambient brightness value is greater than or equal to the preset reference brightness, and the environment is a dark environment when the ambient brightness is less than the preset reference brightness.
S25, when the ambient brightness is greater than or equal to the preset reference brightness, adjusting display parameters of the display device, wherein the display parameters comprise at least one of screen brightness, color saturation and color temperature;
the present embodiment can adjust at least one of the screen brightness, the color saturation, and the color temperature, and the frame brightness value of the display device. The controller may be configured to preset a corresponding relationship between the brightness level and the display parameter, and the specific display parameter may be queried from the corresponding relationship, which may be a mapping table or a graph. Because the environment brightness is divided into a plurality of grades, each grade corresponds to a brightness range, in the specific implementation, the brightness grade of the current environment brightness can be further determined to adjust the display parameters of the display equipment, so that the adjustment is more accurate.
And S26, adjusting the opening of the dynamic expansion switch according to the environment brightness to adjust the picture brightness value of the display equipment.
In this embodiment, the opening degree of the dynamic expansion switch may be divided into a plurality of levels, for example, a strong level, a medium level, and a weak level, the current of the light emitting diode corresponding to each gear is different, and the higher the gear is, the larger the current is. When the current intensity is increased, the image brightness value of the display screen is increased, when the current intensity is reduced, the image brightness value of the display screen is reduced, the change of the image brightness value is reflected on the color change of the display image, if the reduction of the ambient brightness is detected at the moment, the image brightness value is reduced, the phenomenon that the image brightness is low and the display is cold after the light brightness is reduced is avoided, when the increase of the ambient brightness is detected at the moment, the image brightness value is improved, the phenomenon that the highlight display is too bright and beautiful after the light brightness is increased is avoided, the display parameters and the image brightness value are combined and adjusted, and the image display effect of the display screen is improved.

s28: when the display device is not a light emitting diode display device, a current display state is maintained.
For the display panel that is not a led, the brightness of the display panel cannot be adjusted by adjusting the current of the leds, for example, the lcd only adjusts the brightness of the display panel by changing the backlight module or the liquid crystal deflection, so that the dynamic expansion switch can be set when the display panel is a led, and the adjustment of the display parameters (including at least one of the screen brightness, the color saturation and the color temperature) of the display device cannot be achieved only by adjusting the leds, such as adjusting the light emission of the backlight module mentioned above. In one embodiment, the current display state is maintained when the display device is not a light emitting diode display device.
Based on the foregoing embodiment, in a further aspect, the step of adjusting the display parameter of the display device includes:
acquiring a first ambient brightness range in which ambient brightness is located;
acquiring a display parameter corresponding to the first environment brightness range according to a mapping relation between a preset environment brightness range and the display parameter;
and controlling the display equipment to operate according to the acquired display parameters.
In this embodiment, the controller is provided with a corresponding relationship between the display parameters and the ambient brightness levels, such as a mapping table or a graph, in the mapping table, the preset ambient brightness ranges of different levels correspond to the display parameters, and the corresponding relationship may be one-to-one, or the same level corresponds to different values and different types of display parameters, for example, a first preset ambient brightness range corresponds to two screen brightness values, and a user may select the two screen brightness values, and one preset ambient brightness range corresponds to one screen brightness when one corresponds to the other.
