Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
Fig. 1 is a schematic diagram illustrating a display control method according to an embodiment of the present disclosure. The display control method shown in this embodiment may be applied to a display panel, which may be a liquid crystal display panel or an organic light emitting diode display panel, and the display panel includes a plurality of regions.
As shown in fig. 1, the display control method may include the steps of:
in step S1, detecting at least one target area of the plurality of areas, the target area having a brightness different from a preset brightness according to a preset display signal;
in step S2, obtaining difference information between the brightness displayed by the target area according to the preset display signal and the preset brightness;
in step S3, determining a target gamma curve from a plurality of gamma (gamma) curves associated with the target region according to the difference information;
in step S4, the target area is controlled to display an image according to the target gamma curve.
In one embodiment, a set of gamma curves may be configured separately for each region in the display panel, each region being associated with a set of gamma curves, each set of gamma curves comprising a plurality of gamma curves. The gamma curve is a curve for representing the relation between gray scale and brightness.
In one embodiment, the same display signal, for example, the same electric signal such as current, voltage, etc., may be input to each pixel unit of the display panel, and ideally the brightness displayed by all the regions according to the display signal is equal to a preset, but for some reason, the brightness displayed by the partial regions is different from the preset brightness.
According to the embodiment of the disclosure, the difference information between the brightness displayed by the target area according to the preset display signal and the preset brightness can be obtained, then the target gamma curve is determined in a plurality of gamma curves associated with the target area according to the difference information, and further the image is displayed according to the target gamma curve. The brightness of the display image of the target area is consistent with the ideal condition, so that the display image on the whole of the display panel is uniform in brightness, and a good display effect is realized.
In one embodiment, the difference information may be a difference value or a ratio.
Taking the difference information as an example, for example, the preset luminance is 100 nit, the luminance displayed in the area a is 80 nit, the luminance displayed in the area B is 120 nit, then the difference information between the luminance displayed in the area a and the preset luminance is-20 nit, and the difference information between the luminance displayed in the area B and the preset luminance is 20 nit.
That is, based on the gray level corresponding to the received display signal, such as gray level 127, the A region is based on the currently used gamma curve L 1 The brightness is 20 nits lower than ideal brightness, and the B area is according to the gamma curve D 1 The output brightness is 20 nits higher than the ideal brightness.
Wherein the gamma curve associated with the A region is L 1 To L n N gamma curves are total, and the gamma curve associated with the B region is D 1 To D m A total of m gamma curves.
According to the difference information of the brightness displayed by the A area and the preset brightness-20 nits, the target gamma curve of the A area can be determined in the n gamma curves, so that the brightness output by the A area according to the target gamma curve when the gray level is 127 is 20 nits higher than the brightness output by the A area according to the currently used gamma curve when the gray level is 127, and when the A area receives a display signal corresponding to the gray level of 127, the brightness higher than the original 20 nits can be output. Therefore, the image is displayed according to the target gamma curve, the brightness displayed in the area A can be the same as the ideal condition as much as possible, and the brightness deviation when the image is displayed in the area A is further reduced.
According to the difference information of the brightness displayed in the B area and the preset brightness of 20 nits, the target gamma curve of the B area can be determined in the m gamma curves, so that the brightness output by the B area according to the target gamma curve when the gray level is 127 is 20 nits lower than the brightness output by the B area according to the currently used gamma curve when the gray level is 127, and when the B area receives a display signal corresponding to the gray level of 127 again, the brightness lower than the original brightness by 20 nits can be output. Therefore, the image is displayed according to the target gamma curve, the brightness displayed in the B area can be the same as the ideal condition as much as possible, and the brightness deviation when the image is displayed in the B area is reduced.
It should be noted that, according to the target gamma curve display image determined in this embodiment, when the gray level is a certain value, the brightness deviation may be completely compensated, but in practical situations, the number of gamma curves associated with the target area is limited, and possibly, in the gamma curves associated with the target area, no gamma curve can completely compensate the brightness deviation when the gray level is a certain value, and then it may be determined that the gamma curve with the absolute value of the brightness deviation as small as possible is the target gamma curve.
Fig. 2 is a schematic diagram illustrating a determination of a target gamma curve among a plurality of gamma curves associated with the target region according to the difference information according to an embodiment of the present disclosure. As shown in fig. 2, the transmittance of at least one of the plurality of regions is different from the transmittance of the other regions, and determining a target gamma curve among the plurality of gamma curves associated with the target region according to the difference information includes:
in step S31, an adjustment coefficient is determined according to the transmittance of the target area;
in step S32, the difference information is adjusted according to the adjustment coefficient;
in step S33, a target gamma curve is determined from among the plurality of gamma curves associated with the target region according to the adjusted difference information.
In one embodiment, since the transmittance of at least one region is different from the transmittance of other regions, the different transmittance may affect the visual effect of the user, and each transmittance may have a different effect on the visual effect of the user.
When the target gamma curve is determined according to the difference information, the embodiment of the disclosure can determine the transmittance of the target area, determine the adjustment coefficient according to the transmittance, adjust the difference information according to the adjustment coefficient, and then determine the target gamma curve according to the adjusted difference information. On the basis of fully considering the influence of the transmittance on the visual effect, the difference information is adjusted through the adjustment coefficient corresponding to the transmittance (for example, the difference information is multiplied by the adjustment coefficient), and the target gamma curve is determined based on the adjusted difference information, so that the target area displays the image according to the target gamma curve, the displayed brightness can adapt to the transmittance of the target area, the user can feel uniform brightness on the visual effect of watching, and good user experience is guaranteed.
The effect of the transmittance on the luminance may be positive or negative with respect to the transmittance, and may be specifically determined according to the setting. Taking the positive correlation of the effect of the transmittance on the luminance and the transmittance as an example, the larger the transmittance, the larger the adjustment coefficient, that is, for two areas with larger transmittance and smaller transmittance, the more the luminance is compensated by the objective function determined in the area with larger transmittance when displaying the image, in the case that the difference information is the same.
In one embodiment, the difference information includes at least one of:
difference, ratio.
In an embodiment, the display panel is adapted for a terminal, and the method is implemented by a driver chip in the display panel, or by a digital signal processing chip in the terminal, or by an application processor of the terminal.
The terminal can be electronic equipment such as a mobile phone, a tablet personal computer and wearable equipment.
The method shown in the embodiment of the disclosure may be implemented by a driver chip (Display Driver IC, abbreviated as DDIC) of the display panel, or may be implemented by an application processor (Application Processor, abbreviated as AP) of a terminal where the display panel is located.
The method can also be realized by a digital signal processing (Digital Signal Processing, abbreviated as DSP) chip in the terminal, and the DSP chip can have stronger capability of processing digital signals than a driving chip of the display panel, so that the steps in the method can be realized faster, and the steps in the method can be realized by a DPS chip, so that an application processor in the terminal is not occupied, and the load of the application processor is reduced.
