The present application is described in detail below with reference to the attached drawings and alternative embodiments.
As shown in fig. 1, as a first embodiment of the present application, there is disclosed a driving method for driving a display panel including a display area and a non-display area, the display area including a first display area and a second display area, the second display area being located under the first display area in a gravitational direction, the driving method comprising the steps of:
s1: dividing the second display area into a plurality of sub-display areas;
s2: detecting a preset signal, and if the preset signal is detected, controlling the display panel to enter a display adjustment mode; and
s3: detecting the actual brightness of each sub-display area, comparing the actual brightness of each sub-display area with preset target brightness to calculate brightness difference, and adjusting the actual brightness of each sub-display area to the target brightness based on the brightness difference.
The display panel structure is that two layers of glass (TFT array substrate and CF color film substrate) are clamped by using frame glue to form a middle liquid crystal material; when in use, light emitted by the backlight source sequentially passes through the liquid crystal layer and the CF substrate from the TFT array substrate. Based on this display principle, on a screen where gravity mura has occurred, a significant difference has occurred in the light intensity reaching the CF substrate; according to the method, the area where the uneven display phenomenon (such as the Mura phenomenon) is easy to occur is divided into a plurality of sub-display areas, when a preset signal is received, a display adjustment mode is entered, the actual brightness of each sub-display area is detected, the actual brightness of each sub-display area is compared with the preset target brightness to calculate the brightness difference, the actual brightness of each sub-display area is adjusted to the target brightness based on the brightness difference, the light intensities of different areas are utilized to be different and corresponding information is collected and returned to a data driving chip, the data driving chip can adjust the liquid crystal driving voltage corresponding to the different areas, and finally the adjustment of the brightness of the different areas is realized, so that the uneven brightness problem of a second display area which is easy to generate the Mura phenomenon is solved, the brightness difference of the whole display area of the display panel is reduced, and the quality and the display quality of a display picture are improved.
In step S1, the area of each sub-display area is the same, i.e. the second display area is divided into a plurality of sub-display areas with the same shape and the same area; of course, the area and shape of each sub-display area may be different, the sub-display area may be divided into smaller areas in the place where the gravity mura phenomenon is serious, so as to realize finer adjustment, the severity of the gravity mura is generally that the middle area is larger than the areas on two sides, and the lower area is larger than the upper area, so that the areas of the sub-display areas distributed from two sides of the second display area to the middle are sequentially reduced.
Generally, if the second display area is set in a partitioning manner, the screen partition corresponding to the second display area may be partitioned by using 6×9 and 8×15 areas, and the more sub-display areas obtained by the partitioning, the better the picture improvement effect.
In step S2, the preset signals include a start-up signal, a pure white picture driving signal and a pure black picture driving signal; detecting a starting signal, a pure white picture driving signal and a pure black picture driving signal, and if the starting signal, the pure white picture driving signal and the pure black picture driving signal are detected, controlling the display panel to enter a display adjusting mode; the adjustment mode is started, but not at any time, and normally, when the device is started, pure white or pure black pictures are adjusted, so that the problem of picture delay caused by adjustment when a user watches the device is avoided.
Specifically, when the display panel is started, because a certain cache exists in the display panel, a user cannot immediately watch a picture to be watched, a preset signal is generated in the time period, the display adjustment mode is entered, adjustment is completed before the user watches the picture to be watched, adjustment is avoided when watching, and the user can bring about complaints caused by visual angle difference; of course, it is also possible to generate a preset signal to enter a display adjustment mode to realize mura adjustment when the user switches channels or makes a screen switch. In addition, the preset signal can be generated when the pure-color picture is displayed, and when the pure-white picture and the pure-black picture are displayed, as the data are in two critical values and serve as the maximum adjusting range, the brightness value referenced during mura adjustment can be more representative, the compensation obtained by debugging in the range is more accurate, and the application range is larger.
In addition, a timing module may be disposed in the display panel, where the timing module counts the usage time of the display panel, and when the counted time period exceeds the preset time period, the timing module generates the preset signal, as shown in fig. 2, and as a second embodiment of the present application, unlike the first embodiment, the driving method further includes the steps of:
s12: the using time of the display panel is timed, and when the timed duration exceeds the preset duration, the timing module generates the preset signal;
step S12 is started after a certain use time is required to be met between step S1 and step S2, and the display adjustment mode is normally in a closed state, so that the phenomenon that the display adjustment mode is triggered by recoverable brightness difference caused by other factors to cause power consumption loss is avoided; in addition, after a certain service life, liquid crystal in the display panel is affected by gravity and can be gathered to a second display area of the display panel, uneven display, namely mura phenomenon is generated, after a display adjustment mode is triggered at the moment, the mura phenomenon in the second display area can be improved, customers feel that products are more intelligent, automatic repair and display problems can be realized, accordingly, better watching experience is brought to viewers, and satisfaction of the customers is improved.

Further, the display panel comprises a plurality of photoresistors, each photoresistor is arranged corresponding to one sub-display area, the number of the photoresistors is smaller than or equal to that of the sub-display areas, and each sub-display area corresponds to one photoresistor under the condition that the photoresistors are equal to each other; in the case that the two are different, the photoresistors may be selectively set according to the brightness difference condition of each sub-display area, for example, the photoresistors are set in the sub-display area with very large brightness difference, and the photoresistors are not set in the area with insignificant brightness difference, and generally, the step S3 includes:
s31: the photoresistor generates photosensitive current according to illumination intensity, calculates actual brightness according to the photosensitive current, compares the actual brightness of each sub-display area with preset target brightness to calculate brightness difference, and adjusts data driving voltage based on the brightness difference to enable the brightness of each sub-display area to be restored to the target brightness.
The corresponding photosensitive current is generated through the photosensitive resistor and the illumination intensity, the actual brightness is calculated through the photosensitive current, the actual brightness of each sub-display area is compared with the preset target brightness to calculate the brightness difference, the data driving voltage is adjusted based on the brightness difference so that the brightness of each sub-display area is restored to the target brightness, the accuracy of brightness adjustment is improved, and the brightness of the adjusted display area is more uniform and finer.
It should be noted that, the limitation of each step in the present solution is not to be considered as limiting the sequence of steps on the premise of not affecting the implementation of the specific solution, and the steps written in the previous step may be executed before, may be executed after, or may even be executed simultaneously, so long as the implementation of the present solution is possible, all should be considered as falling within the protection scope of the present application.

In addition, a timing module 170 may be disposed in the display panel, where the timing module 170 counts the usage time of the display panel 100, and when the counted time exceeds a preset time, the timing module generates the preset signal, that is, the display adjustment mode needs to be started after a certain usage time is met, and is normally in a closed state, so that the power consumption loss caused by that the recoverable brightness difference caused by other factors falsely triggers the display adjustment mode is avoided; in addition, after a certain service life, liquid crystal in the display panel is affected by gravity and can be gathered to a second display area of the display panel, mura phenomenon is generated, after a display adjustment mode is triggered at the moment, the mura phenomenon in the second display area can be improved, a customer feels more intelligent, the problem of automatic repair and display can be realized, and accordingly a better watching experience is brought to a viewer, and satisfaction of the customer is improved.
In order to provide a more convenient adjustment mode for a user and create a scene for the user to interact with a display panel, a controller 180 for controlling the display adjustment mode to be started can be further arranged on the display panel to provide a description and introduce, when the user sees that serious brightness unevenness occurs on a picture of the display panel, the controller 180 for starting the display adjustment mode can be pressed down to generate a preset signal, and when the preset signal is detected in the display panel, the display panel is controlled to enter the display adjustment mode to improve brightness unevenness; the brightness difference of the whole display area of the display panel is reduced, and the quality of the display picture and the display quality are improved.
As a fourth embodiment of the present application, referring to fig. 4 and 5, unlike the above embodiments, the display area 200 further includes a third display area 230, and the first display area 210, the second display area 220, and the third display area 230 are sequentially arranged along the gravity direction to form the display area 200, where the area of the first display area 210 is larger than the area of the second display area 220, and the area of the second display area 220 is larger than the area of the third display area 230; the area of the second display area 220 is 0.05-0.09 times the total area of the display area.
The most serious place of the general gravity mura area is mainly distributed in the second area 220, the position of the second area is between the first area and the third area, and the area of the second area is 0.05-0.09 times of the total area of the display area, or the gravity mura is mainly concentrated in the lower quarter to fifth of the panel; by defining a specific mura area, a photoresistor 140 is installed for the mura area at a specific position, a photosensitive current is generated through the photoresistor based on illumination intensity, actual brightness is calculated according to the photosensitive current, the actual brightness of each sub-display area is compared with preset target brightness to calculate brightness difference, and data driving voltage is adjusted based on the brightness difference so that the brightness of each sub-display area is restored to the target brightness.
The implementation mode is as follows: using negative photosensitive materials (the resistance is inversely proportional to the intensity of illumination)
For example, when the gravity mura occurs, in the gravity mura area (not necessarily below the screen, but related to the placement direction of the screen, so the invention can correspond to all the uneven brightness phenomena of the screen or the weak illumination intensity received by the mura) CF substrate, so the resistance value of the photoresistor in the gravity mura area is larger, the current flowing through the photoresistor is obviously smaller than that in other areas, and the data driving chip can raise the brightness of the gravity mura area by raising the liquid crystal driving voltage for the area with smaller photoresistor current (here, the invention is described in a normally black display mode, and the normally white display mode is to lower the liquid crystal driving voltage).
The implementation mode II is as follows: using positive photosensitive materials (resistance magnitude proportional to intensity of illumination)
For example, when gravity mura occurs, the light intensity is weaker in the CF substrate in the gravity mura region, so that the resistance of the photoresistor in the gravity mura region is smaller, the current flowing through the photoresistor is obviously larger than that in other regions, and the data driving chip can raise the brightness of the gravity mura region by increasing the liquid crystal driving voltage for the region with larger photoresistor current (here, the description is in a normally black display mode, and the normally white display mode is to lower the liquid crystal driving voltage).
Further, the display panel 100 includes a color film substrate 120 and an array substrate 110, a photo resistor 140 is disposed on the color film substrate 120 corresponding to the sub-display area 221, the photo resistor 140 is disposed corresponding to the light shielding layer 111 on the array substrate, and the resistivity of the photo resistor 140 corresponding to the sub-display area 221 arranged from two sides of the second display area 220 to the middle is sequentially reduced. In the second display area 220, the middle sub-display area is greatly affected, so that the set resistivity is smaller, the current change is significantly more accurate to adjust the brightness of the middle sub-display area, in addition, the middle can be further subdivided, the influence of the middle sub-display area 221 near the lower part is larger, and the set resistivity is smaller in the area near the lower part of the design middle.
