All the above optional technical solutions may be combined arbitrarily to form the optional embodiments of the present disclosure, and are not described herein again.
Fig. 2 is a flowchart illustrating a screen display method according to an exemplary embodiment, and as shown in fig. 2, the screen display method is used in a foldable device, and includes the following steps.
In step S201, the foldable device acquires display attribute information of the flexible display screen.
The foldable device is provided with a foldable shell and a flexible display screen, and can be folded or unfolded according to the requirements of users. When the foldable device is in the unfolded state, a larger display screen can be provided to meet the watching requirements of users; when the foldable state is in the folded state, the occupied space can be reduced to meet the portability requirement of the user. Common foldable devices include foldable smart phones, tablet computers, notebook computers, and the like, although the above is not exhaustive, and in fact, the foldable devices are not limited to the above listed devices.
The display attribute information of the flexible display screen comprises at least one of folding times, lighting time and the like. The lighting time includes lighting time of the region, lighting time of the pixel unit, and the like. The obtaining mode of the attribute information of the flexible display screen includes but is not limited to: when the state of the flexible display screen is changed, for example, from a folded state to an unfolded state, or from the unfolded state to the folded state, the foldable device records the folding times of the flexible display screen through a Central Processing Unit (CPU); when the flexible display screen is in a lighting state, the foldable device records the lighting time period of each area or pixel unit and the like through the CPU.
In step S202, the foldable device determines a region type of each region on the flexible display screen according to the display attribute information of the flexible display screen.
The region types may include a common display region, an unused display region, and a transition region. The common display area is a display area which is frequently used by a user in a folded state; the non-use display area is a display area which is not used frequently by a user in a folded state relative to the common display area; the transition area is an area between the normal display area and the non-normal display area.
In a first case, different areas on the flexible display screen of the foldable device may be predetermined, for example, when the foldable device is applied to display, the flexible display screen of the foldable device is divided into three areas, which are a first display area, a folding area and a second display area according to functions of the different areas, one of the first display area and the second display area is a common display area, and the other is an unused display area, where the folding area is a transition area. In this case, when the foldable device determines the region type of each region on the flexible display screen according to the display attribute information of the flexible display screen, the following two ways may be adopted:
in the first mode, the foldable device acquires the folding times of the flexible display screen, determines the use frequency of each area on the flexible display screen according to the folding times of the flexible display screen, and further determines the area type of each area on the flexible display screen according to the use frequency of each area on the flexible display screen.
In a possible mode, when the use frequency of any display area on the flexible display screen is higher than a preset threshold value, the foldable device determines that the area is a common display area; when the use frequency of any display area on the flexible display screen is lower than a preset threshold value, the foldable device determines the area as an emergency display area. The preset threshold value can be set according to past use experience.
In another possible manner, the foldable device obtains the frequency of use of the first display area and obtains the frequency of use of the second display area, and then determines the display area with relatively higher frequency of use in the first display area and the second display area as a common display area, and then determines the other display area as an uncommon display area.
In the second mode, the foldable device acquires the lighting time of each area on the flexible display screen, and further determines the area type of each area on the flexible display screen according to the lighting time of each area on the flexible display screen.
In one possible mode, when the lighting duration of any display area on the flexible display screen is higher than a preset duration, the foldable device determines that the area is a common display area; when the lighting time of any display area on the flexible display screen is lower than the preset time, the foldable device determines the area as an emergency display area. The preset duration can be set according to past use experience.
In another possible manner, the foldable device obtains the lighting time length of the first display area, obtains the lighting time length of the second display area, determines the display area with the relatively longer lighting time length in the first display area and the second display area as a common display area, and then determines the other display area as an uncommon display area.
In the second case, the different areas on the flexible display of the foldable device are not predetermined, but determined according to the subsequent use. For the situation, the foldable device can obtain the lighting time length of each pixel unit on the flexible display screen, and the pixel units which are adjacent to each other and have the lighting time length within the same threshold value range are divided into the same area according to the lighting time length of each pixel unit, and after all the pixel units are processed by adopting the mode, the flexible display screen can be finally divided into different areas.
After the flexible display screen is divided into different regions, the foldable device may determine a region type of each region according to a lighting time period of each divided region. Specifically, when the lighting time length of any one area on the flexible display screen is longer than a preset time length, the foldable device determines that the area is a common display area; when the lighting time of any area on the flexible display screen is lower than the preset time, the foldable device determines that the area is an emergency display area. The foldable device then determines the area between the common display area and the non-common display area as a transition area. The preset duration can be set according to past use experience.
In step S203, the foldable device performs brightness adjustment in different ways for each region according to the region type of each region.
The foldable device may be brightness adjusted in different ways for regions belonging to different region types, taking into account that the extent of attenuation of the luminescent material during use is different for regions of different region types. The method specifically comprises the following conditions:
the first case, for the common display area.
In an embodiment of the disclosure, when the region type of any region is a common display region, because the lighting time of the common display region is longer than that of the non-common display region, and the loss of the luminescent material is relatively large, the luminance value of each pixel unit in the common display region is smaller than that of each pixel point in the non-common display region, so that the foldable device can adjust the luminance of the common display region by increasing the luminance value of each pixel unit in the common display region, so as to achieve the purpose of improving the display effect.
Specifically, the foldable device can perform light compensation on each pixel unit in the common display area to increase the brightness value of each pixel unit in the common display area; the foldable equipment can also increase the gray value of each pixel unit in the common display area so as to increase the brightness value of each pixel point in the common display area; the foldable device may also increase the drive current of the common display area to increase the brightness value of each pixel cell within the common display area.
Of course, the foldable device may also adopt other ways to increase the brightness value of each pixel unit in the common display area, which is not described herein again.
The second case, for the unused display area.
In another embodiment of the disclosure, when the area type of any one area is the non-use display area, because the bright point duration of the non-use display area is shorter than the lighting duration of the common display area, and the loss of the luminescent material is relatively small, the luminance value of each pixel unit in the non-use display area is larger than the luminance value of each pixel point in the common display area, so that the foldable device can adjust the luminance of the non-use display area by reducing the luminance value of each pixel point in the non-use display area, so as to achieve the purpose of improving the display effect.
Specifically, the foldable device can reduce the gray value of each pixel unit in the unused display area so as to reduce the brightness value of each pixel point in the unused display area; the foldable device may also reduce the drive current of the inactive display area to reduce the brightness value of each pixel cell within the inactive display area.
Of course, the foldable device may also reduce the brightness value of each pixel unit in the unused display area in other ways, which will not be described herein.
The third case, for the transition region.
In another embodiment of the present disclosure, when the region type of any one region is a transition region between the common display region and the non-common display region, the foldable device may adjust the brightness values of the respective pixel units in the region such that the brightness contrast between the common display region and the non-common display region is no longer significant.
Specifically, for each pixel cell within the transition region, the foldable device may gradually decrease the luminance value of the pixel cell as the distance between each pixel cell and the boundary of the non-common display region increases, such that the luminance value smoothly transitions within the transition region. When a user watches the flexible display screen, the brightness value of the flexible display screen can be considered to be uniform in the aspect of viewing and feeling, and the purpose of improving the display effect can be achieved.
Taking the above example of brightness adjustment only for regions belonging to the same region type at a time, in practice, in order to better solve the problem of uneven brightness in different regions, the foldable device may also perform brightness adjustment for regions belonging to different region types at the same time according to the above method. For example, the foldable device may increase the brightness value of each pixel cell in the common display area while decreasing the brightness value of each pixel cell in the non-common display area; the foldable device can also reduce the brightness value of each pixel unit in the non-common display area, and simultaneously carry out transition processing on the brightness value of each pixel unit in the transition area; the foldable device can also increase the brightness value of each pixel unit in the common display area and simultaneously perform transition processing on the brightness value of each pixel unit in the transition area; the foldable device may also increase the luminance value of each pixel unit in the common display region and decrease the luminance value of each pixel unit in the non-common display region, while performing a transition process on the luminance values of each pixel unit in the transition region.
It should be noted that, the above description is given by taking the region type including the common display region, the non-use display region and the transition region as an example, and of course, the region type may also include only the common display region and the non-use display region, but not the transition region, at this time, after the common display region and the non-use display region are determined according to the display attribute of the flexible display screen, the foldable device may process at least one type of region in the common display region and the non-use display region according to the above processing method, so as to improve the screen display effect.
In step S204, the foldable device performs screen display based on the adjusted brightness value of each region.
After the brightness of the regions on the flexible display screen is adjusted through the steps, the foldable device performs screen display based on the adjusted brightness value of each region. Because the brightness contrast of each adjusted area is smaller than that before adjustment, the brightness in different display areas is more uniform, and the screen display effect is better.
According to the method provided by the embodiment of the disclosure, the display attribute information of the flexible display screen is obtained, the area type of each area on the flexible display screen is determined according to the display attribute information, and then the screen for adjusting the brightness of different area types is displayed. By adjusting the brightness of different areas, the brightness of different display areas can be uniform, and the display effect of the screen is greatly improved.
