As shown in fig. 2, a schematic flow chart of an embodiment of a method for improving display non-uniformity of a panel in an embodiment of the present application is shown, where the method for improving display non-uniformity of a panel includes:
21. acquiring the heating temperature of the display panel, and determining the overheating area in the display panel according to the heating temperature.
In the embodiment of the application, the superheat region in the display panel needs to be determined according to the heat generation temperature of the panel after operation, so that the heat generation temperature corresponding to the display panel after operation can be obtained.
In the actual process of acquiring the heat generation temperature, the display panel is generally divided into a plurality of display areas, and the heat generation temperatures corresponding to the plurality of display areas are acquired to obtain a plurality of heat generation temperatures.
In some embodiments, the display panel may be divided into a plurality of display areas, and any display area in the plurality of display areas may be used as a target display area; at this time, the heating temperature corresponding to the target display area may be measured, and it is determined whether the heating temperature is within the preset temperature range. If the heating temperature is within the preset temperature range, the target display area can be determined to be an overheating area with overhigh temperature.
The preset temperature range is a normal temperature range corresponding to the normal working of the display panel, the first temperature range is obtained comprehensively according to the working condition of the panel, the heat dissipation condition of the panel material and the like when the display panel is designed, and the first temperature ranges corresponding to different display panels are different. Thus, in embodiments of the present application, the first temperature range is known and determined.
Since the display panels each include a plurality of pixel units, in some embodiments, one pixel unit may be regarded as one display region, that is, each of the plurality of display regions includes one pixel unit. Acquiring the heat generation temperature of the display panel at this time to determine the overheated area in the display panel according to the heat generation temperature may include:
taking a display area corresponding to any pixel unit in the plurality of pixel units as a target display area, and measuring the heating temperature corresponding to one pixel unit in the target display area; and judging whether the heating temperature corresponding to one pixel unit is within a preset temperature range, and if the heating temperature is not within the preset temperature range, determining that the target display area is the overheating area. At this time, the heat generation temperature corresponding to one pixel unit in the target display area is the overheat heat generation temperature corresponding to the overheat area.
In the above embodiments, there may be a plurality of overheated pixel units in one display panel at the same time, that is, the display panel may include a plurality of overheated areas at the same time.
In the above embodiments, only one pixel unit is included in one display region, but in other embodiments of the present application, one display region may also include a plurality of pixel units at the same time. Specifically, in some embodiments, the display panel also includes a plurality of pixel units arranged in an array, where each of the plurality of display regions includes at least one row or at least one column of pixel units; i.e. each display area comprises two or more pixel units.
At this time, acquiring the heat generation temperature of the display panel to determine the overheated area in the display panel according to the heat generation temperature may include:
taking a display area corresponding to at least one row or at least one column as a target display area; measuring heating temperatures corresponding to pixel units of at least one row or at least one column in the target display area to obtain a plurality of heating temperatures; respectively judging whether each heating temperature in the plurality of heating temperatures is within a preset temperature range; and if the preset number of heating temperatures in the plurality of heating temperatures are not within the preset temperature range, determining that the target display area is the overheating area.
Specifically, at this time, since one display region includes at least one row or at least one column of pixel units, it is necessary to acquire a plurality of heating temperatures corresponding to the at least one row or at least one column of pixel units; and judges whether each of the plurality of heat generation temperatures is overheated, that is, within a normal temperature range, respectively. And if the heating temperature exceeding a certain number is not in the normal temperature range, determining that the display area is overheated at the moment, namely the display area is an overheated area.
In some embodiments, the preset number of heating temperatures may be generally 50% of the heating temperature in the current display area; that is, if the heating temperature exceeding 50% is not within the normal temperature range, it may be determined that the current display area is the overheated area. In other embodiments, the heating temperatures of the preset number may also be adaptively adjusted according to actual requirements, which is not limited in this application.
22. And adjusting the driving signal corresponding to the overheating area according to the heating temperature corresponding to the overheating area to obtain the adjusted driving signal.
23. And driving the overheating area by using the adjusted driving signal, and determining the target brightness corresponding to the overheating area.
After the superheat region in the display panel is determined according to the heating temperature, the driving signal corresponding to the superheat region can be adjusted, so that the superheat region generates a new heating temperature under the driving of the new driving signal until the temperature of the superheat region is normal.
Specifically, the driving signal corresponding to the superheat region may be adjusted according to the heating temperature corresponding to the superheat region, so as to obtain an adjusted driving signal; and redriving the overheated area by using the adjusted driving signal, and determining the target brightness of the overheated area under the drive of the adjusted driving signal.
24. And calculating a brightness difference value between the target brightness and the preset brightness.
25. And judging whether the brightness difference value is within a preset brightness difference value range.
26. And if the brightness difference value is not within the preset brightness difference value range, readjusting the adjusted driving signal corresponding to the overheating area until the brightness difference value between the target brightness and the preset brightness is within the preset brightness difference value range.
After the target brightness of the superheat region under the drive of the adjusted drive signal is determined, whether the superheat region is normal at the moment needs to be judged according to the second brightness, so that a brightness difference value between the target brightness and the preset brightness needs to be calculated; and judging whether the brightness difference value is within a preset brightness difference value range.
The preset brightness is the brightness corresponding to the normal display of the display panel and is similar to the preset temperature range, and the preset brightness is determined already when the display panel is prepared; the preset brightness of different display panels is different.
Therefore, if the difference value between the current corresponding brightness of the overheating area and the normal brightness is not within the preset brightness difference value range, it indicates that the picture displayed in the overheating area is still not normal, and the picture still needs to be adjusted; therefore, the adjusted driving signal corresponding to the overheating area is readjusted until the overheating area is displayed normally.
According to the method for improving uneven display of the panel picture, the heating temperature corresponding to the display panel is obtained firstly, and the overheating area in the display panel is determined according to the heating temperature; adjusting a driving signal corresponding to the overheating area according to the heating temperature corresponding to the overheating area to obtain an adjusted driving signal, and driving the overheating area by using the adjusted driving signal; and after the adjusted driving signal is determined to drive the overheating area, the target brightness corresponding to the overheating area is determined to judge whether the overheating area is still overheated according to the target brightness, and if so, the adjusted driving signal corresponding to the overheating area is continuously adjusted until the overheating area is not overheated any more. The method comprises the steps of firstly determining a superheat region according to the temperature of a display panel, and then continuously adjusting a driving signal corresponding to the superheat region according to the temperature until the superheat region is not overheated any more; the adjusting method can effectively improve the problem of panel overheating and avoid the problem of uneven picture display.
In some embodiments of the present application, adjusting the driving signal corresponding to the superheat region according to the heat generation temperature corresponding to the superheat region may include:
and adjusting a first duty ratio corresponding to the driving signal according to the heating temperature to obtain an adjusted driving signal, wherein the adjusted driving signal corresponds to a second duty ratio.
The larger the duty cycle, the larger the value of the drive signal; the larger the value of the driving signal is, the more heat is generated in the same time, resulting in a higher heating temperature corresponding to the display panel.
