Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary only for the purpose of explaining the embodiments of the present application, and are not to be construed as limiting the embodiments of the present application.
Referring to fig. 1, the present application provides a driving method of a dimming panel, including:
01: providing a first voltage to the dimming panel to increase transparency of the dimming panel when the dimming panel is in a dark state;
02, controlling the first voltage to be continuously preset for time so that the transparency of the dimming panel is greater than the preset transparency;
and 03, after the first voltage lasts for the preset time, providing a second voltage to the liquid crystal driving panel to keep the transparency of the dimming panel larger than the preset transparency, wherein the first voltage is larger than the second voltage.
Accordingly, referring to fig. 2, the present application also provides a driving apparatus 100 for a dimming panel, and the driving method of the present application can be implemented by the driving apparatus 100.
The driving apparatus 100 includes a first providing module 110, a control module 120, and a second providing module 130. Step 01 may be implemented by the first providing module 110, step 02 may be implemented by the control module 120, and step 03 may be implemented by the second providing module 130.
In other words, the first providing module 110 is configured to provide the first voltage to the dimming panel when the dimming panel is in a dark state, so as to increase the transparency of the dimming panel. The control module 120 is configured to control the first voltage to last for a preset time, so that the transparency of the dimming panel is greater than a preset transparency. The second providing module 130 is configured to provide a second voltage to the liquid crystal driving panel after the first voltage lasts for a preset time, so as to keep the transparency of the dimming panel greater than the preset transparency, and the first voltage is greater than the second voltage.
The embodiment of the application also provides the electronic equipment. The electronic device includes a memory and a processor. The memory has stored therein a computer program. The computer program, when executed by a processor, causes the processor to implement the above-described driving method. That is, the processor is configured to provide a first voltage to the dimming panel to increase the transparency of the dimming panel when the dimming panel is in a dark state, control the first voltage for a preset time to make the transparency of the dimming panel greater than the preset transparency, and provide a second voltage to the liquid crystal driving panel after the first voltage lasts for the preset time to keep the transparency of the dimming panel greater than the preset transparency, where the first voltage is greater than the second voltage.
According to the driving method, the driving device and the electronic equipment of the dimming panel, under the condition that the dimming panel is in the dark state, the voltage of the dimming panel is adjusted to the first voltage and lasts for the preset time, so that the brightness of the dimming panel is quickly adjusted to be larger than the preset transparency, the voltage is adjusted to the second voltage again until the brightness of the dimming panel is increased to the white state, and therefore the dimming response time is prolonged and the picture display effect is guaranteed.
Please refer to fig. 3 and 4, it should be noted that the dark state means that the transparency of the dimming panel is at a predetermined value, and the bright state means that the transparency of the dimming panel is greater than or equal to the predetermined value, for example, when the transparency of the dimming panel is zero, the dimming panel is determined to be in the dark state, and when the transparency of the dimming panel is greater than ninety percent, the dimming panel is set to be in the bright state. Therefore, whether the dimming panel is in a dark state or a bright state can be judged according to the transparency of the dimming panel.
It should be further noted that the preset time may be a preset time period for supplying the first voltage to the dimming panel, the preset transparency refers to a preset value, the preset transparency is smaller than the maximum transparency of the dimming panel, and the actual value of the preset transparency is not limited, for example, in the present application, the preset transparency may be ninety percent of the maximum transparency of the dimming panel.
In particular, the electronic device may be, but is not limited to, a cell phone, a computer, a tablet, a smart wearable device, a vehicle, and the like. In some examples, the electronic device may include a dimming panel, i.e., the dimming panel is part of the electronic device, e.g., the electronic device is a vehicle, and the dimming panel may be a side window or a sunroof of the vehicle. Of course, in other examples, the electronic device may not include a dimming panel as a separate part.
The dimming panel may be a liquid crystal dimming panel, for example, in this application, the dimming panel may be a dyed liquid crystal panel, and the dyed liquid crystal panel refers to a liquid crystal panel into which a liquid crystal dye is added, so that the liquid crystal panel has a dimming function. The dimming panel can be applied to the fields of vehicles, airplanes, shipborne portholes, automobile skylights, side windows and the like.
The dimming panel can adjust the transparency through voltage adjustment. In addition, in a preset range, the response time of the dimming panel from a bright state to a dark state or from the dark state to the bright state is inversely proportional to the voltage, that is, in the preset range, the larger the voltage value is, the shorter the response time from the dark state to the bright state or from the bright state to the dark state is.
The second voltage may be a voltage required to maintain a bright state of the dimming panel. For example, when the voltage of the dimming panel is 15V, the dimming panel can maintain a bright state. The first voltage and the second voltage are forward voltages, that is, the first voltage and the second voltage are greater than zero, and the first voltage is greater than the second voltage, and the first voltage may be 20V to 40V. The second voltage may be 10 to 20V. The specific values of the first voltage and the second voltage are not limited, and the first voltage can be determined according to the actual brightness of the dimming panel to ensure that no abnormality occurs in the picture, for example, in the present embodiment, the first voltage may be 30V, and the second voltage may be 18V. As can be appreciated, since the first voltage, which is greater than the voltage required to maintain the bright state, is provided to the dimming panel for the preset time in the process of the dimming panel from the dark state to the bright state, the quick reaching of the transparency of the dimming panel to the preset transparency can be accelerated, and the time for the dimming panel to rise from the dark state transparency to the preset transparency is reduced. After the first voltage lasts for the preset time, that is, when the transparency of the dimming panel is greater than the preset transparency, the second voltage for maintaining the bright state is provided to the liquid crystal panel, so that the transparency of the liquid crystal panel is increased from the preset transparency to the transparency of the bright state and the transparency of the bright state is maintained. Therefore, the response time of the dimming panel from a dark state to a bright state is prolonged, and the picture display effect can be ensured.
In some embodiments, the preset time is greater than or equal to a first time period for supplying the first voltage to the dimming panel to adjust the dimming panel from a dark state to a transparency at which the dimming panel maintains according to the second voltage.
In some embodiments, the preset time is a second time period for providing the first voltage to the dimming panel to adjust the dimming panel from the dark state to the maximum transparency, and the second time period is longer than the first time period.
For example, when the dimming panel is in a dark state, the first voltage is provided, the transparency of the dimming panel reaches the preset transparency after 0.1 second, reaches the transparency which can be maintained by the second voltage after 0.2 second, and reaches the transparency which can be maintained by the first voltage after 0.3 second, and the first duration is 0.2 second. The second time period is 0.3 seconds.
Referring to fig. 5, in some embodiments, the driving method further includes:
04, providing a first voltage to the dimming panel in a case that the dimming panel is in a dark state;
05, controlling the first voltage to be switched to a second voltage after different durations so as to obtain a transparency change curve of the corresponding dimming panel;
and 06, determining the preset time according to the transparency change curve.
Referring further to fig. 6, in some embodiments, the driving apparatus 100 further includes a determination module 140, wherein step 04 may be implemented by the first providing module 110, step 05 may be implemented by the control module 120, and step 06 may be implemented by the determination module 140. Or, the first providing module 110 is further configured to provide a first voltage to the dimming panel when the dimming panel is in a dark state, the control module 120 is further configured to control the first voltage to be switched to a second voltage after different durations, so as to obtain a transparency change curve of the corresponding dimming panel, and the second providing module is further configured to determine the preset time according to the transparency change curve.
In some embodiments, the processor is configured to provide a first voltage to the dimming panel when the dimming panel is in a dark state, control the first voltage to switch to a second voltage after different durations to obtain a transparency change curve of the corresponding dimming panel, and determine the preset time according to the transparency change curve.
It can be understood that, since the first voltage is greater than the second voltage, the response time of the dimming panel from the dark state to the bright state according to the first voltage is less than the response time of the dimming panel from the dark state to the bright state according to the second voltage, and the transparency of the dimming panel in the bright state maintained according to the first voltage is greater than the transparency of the dimming panel in the bright state maintained according to the second voltage, while the transparency of the dimming panel is gradually increased during the adjustment from the dark state to the bright state, and the transparency of the dimming panel is increased from the transparency value of the dark state to the preset transparency during the adjustment from the dark state to the bright state according to the first voltage, then increased to the transparency value of the bright state maintained by the second voltage, and finally increased to the transparency of the bright state maintained by the first voltage. If the ambient temperature is lower than the normal temperature, such as 0 ℃, the dimming panel is switched from the first voltage to the second voltage, which is likely to cause the transparency of the dimming panel to change rapidly, resulting in poor image display. Therefore, in order to reduce the image quality defect caused by the rapid decrease of the transparency change (the transparency change is too large, the image becomes dark visually), it is necessary to determine the transparency change curve of the corresponding dimming panel after the first voltage is switched to the second voltage for different durations, and to select the duration with the best effect of the transparency change curve of the dimming panel as the preset time.
For example, in some examples, the ambient temperature is lower than the normal temperature, the first voltage is 30V, the second voltage is 18V, and after the dimming panel is switched to 18V after the voltage is 30V and the duration time is 0.3 s, the transparency changes sharply, so that the image display is poor, while the inversion point is just within 90% transparency, and when the maximum transparency is compared with the maximum transparency at different voltages, the maximum transparency is not reached, i.e., 18V is reduced when 30V lasts for 0.3 s, so that the transparency changes sharply. To reduce this difference in transparency, the duration can be extended slightly based on this, ensuring that the dimming panel decreases to 18V after the transparency of 30V has reached a maximum.
Referring to fig. 7 to 9, in some embodiments, the driving method further includes:
07, providing a third voltage to the dimming panel to increase transparency of the dimming panel when the dimming panel is in a dark state, the third voltage and the first voltage having opposite polarities;
08, controlling the third voltage to be continuously kept for a preset time so that the transparency of the dimming panel is greater than the preset transparency;
09, after the third voltage lasts for the preset time, a fourth voltage is provided to the liquid crystal driving panel to keep the transparency of the dimming panel larger than the preset transparency, and the polarity of the fourth voltage is opposite to that of the second voltage.
Referring to fig. 2, in some embodiments, step 07 may be implemented by the first providing module 110, step 08 may be implemented by the control module 120, and step 09 may be implemented by the second providing module 130. Or, the first providing module 110 is configured to provide a third voltage to the dimming panel to increase the transparency of the dimming panel when the dimming panel is in a dark state, where the polarity of the third voltage is opposite to that of the first voltage, the control module 120 is configured to control the third voltage for a preset time, so that the transparency of the dimming panel is greater than the preset transparency, and the second providing module 130 provides a fourth voltage to the liquid crystal driving panel after the third voltage for the preset time, so as to keep the transparency of the dimming panel greater than the preset transparency, and the polarity of the fourth voltage is opposite to that of the second voltage.
In some embodiments, the processor is configured to provide a third voltage to the dimming panel to increase the transparency of the dimming panel when the dimming panel is in a dark state, the third voltage and the first voltage have opposite polarities, control the third voltage for a preset time to make the transparency of the dimming panel greater than the preset transparency, and provide a fourth voltage to the liquid crystal driving panel after the third voltage for the preset time to keep the transparency of the dimming panel greater than the preset transparency, and the fourth voltage and the second voltage have opposite polarities.
The transparency of the dimming panel is related to the absolute value of the voltage, and is independent of the polarity of the voltage, i.e., the transparency of the dimming panel can be changed equally by supplying a forward voltage or a reverse voltage to the dimming panel. The first voltage and the third voltage have the same absolute value and opposite polarity, and the second voltage and the fourth voltage have the same absolute value and opposite polarity, for example, if the first voltage is 30V, the second voltage is 18V, the third voltage is-30V, and the fourth voltage is-18V.
Referring to fig. 10, in some embodiments, step 02 includes:
021: obtaining the ambient temperature;
022: and determining the preset time according to the ambient temperature.
In some embodiments, the substeps 021 and 022 can be implemented by the control module 120, or the control module 120 can be further configured to obtain an ambient temperature and determine the preset time according to the ambient temperature.
In some embodiments, the processor is configured to obtain an ambient temperature and determine the preset time based on the ambient temperature.
It should be noted that the preset time is also negatively related to the ambient temperature, that is, the lower the temperature is, the longer the response time of the dimming panel from the dark state to the bright state is, and therefore, the preset time can be determined according to the ambient temperature, for example, when the ambient temperature is 25 degrees celsius, the preset time can be 0.3 seconds, when the ambient temperature is 10 degrees celsius, the preset time can be set to 0.4 seconds, when the ambient temperature is 0 degrees celsius, the preset time can be set to 0.65 seconds, and when the ambient temperature is-10 degrees celsius, the preset time can be set to 1.35 seconds. Of course, it is understood that the above examples are merely illustrative, and the relationship between the duration of the preset time and the ambient temperature can be obtained through time product testing. Therefore, the influence of the ambient temperature on the response time of the dimming panel from the dark state to the bright state can be reduced to the maximum extent.
Referring to fig. 11, in some embodiments, the driving method further includes:
10: and supplying a fifth voltage to the dimming panel to restore the dimming panel to a dark state.
Referring to fig. 6, in some embodiments, the driving apparatus 100 further includes a third providing module 150, and step 10 can be implemented by the third providing module 150. Alternatively, the third providing module 150 may be configured to provide a fifth voltage to the dimming panel to restore the dimming panel to the dark state.
In some embodiments, the processor is configured to provide a fifth voltage to the dimming panel to restore the dimming panel to a dark state.
Referring to fig. 8, the fifth voltage may be 0V, that is, when the voltage applied to the dimming panel is zero or no voltage is applied to the dimming panel, the dimming panel is restored to the dark state. Thus, the switching of the dimming panel from a bright state to a dark state is realized.
