In the related art, the Mini LED is limited by the manufacturing process, and basically can only be driven in PM (Passive Mode), i.e., the PM-Mini LED. When the switching frame rate is too low, human eyes can observe flickering or black stripes of the brightness change, and the display effect is greatly influenced. The PM-Mini LED is generally used for outdoor large screens, extremely high display brightness is needed, and the constant current needed to be driven by the PM-Mini LED is determined to be set to be higher. Therefore, the display luminance in the shortest light-emitting period cannot reach a lower gray scale, and the gray scale cannot be made finer at a low gray scale. It is often desirable to achieve a finer gray scale display at the expense of refresh rate. This results in black stripes at low gray levels that are easily visible to the human eye due to the reduced refresh rate.
Based on this, the present application provides a solution to the above technical problem, the details of which will be set forth in the following embodiments.

In one example, the transmission device 106 may be a Radio Frequency (RF) module, which is used for communicating with the internet in a wireless manner.
In this embodiment, a display control method is provided, and fig. 2 is a flowchart of a display control method according to an embodiment of the present invention, as shown in fig. 2, the flowchart includes the following steps:
step S202, determining a target gray scale to be displayed in the display area.
Optionally, the number of display areas is plural. For example, a mini LED display screen may include at least one display area. Such as 2 display areas. Or an even number of display areas such as 4, 6, 8, etc.
Optionally, the number of pixel points in each display region may be equal. For example, each display region includes at least 2 pixels, one pixel including a set of RGB LEDs.
Of course, in actual use, the number of the pixel points in each display region may also be unequal, and is not specifically limited herein.
Step S204, acquiring a first gray scale and a second gray scale corresponding to the target gray scale, wherein the target gray scale is between the first gray scale and the second gray scale;
step S208, controlling a first sub-display area in the display area to display the first gray scale, and controlling a second sub-display area in the display area to display the second gray scale, so that the display area displays the target gray scale, wherein the first sub-display area is an area where a first group of RGB light-emitting diodes with a first quantity are located, the first group of RGB light-emitting diodes are distributed in at least two pixel points, the second sub-display area is an area where a second group of RGB light-emitting diodes with a second quantity are located, and the second group of RGB light-emitting diodes are distributed in at least two pixel points.
In the above embodiment, the first sub-display region and the second sub-display region may each include a plurality of pixel points, and each pixel point includes a group of RGB light emitting diodes. After the target gray scale to be displayed in the display area is determined, the first gray scale and the second gray scale corresponding to the target gray scale can be determined according to the target gray scale, the first sub-display area is controlled to display the first gray scale, the second sub-display area is controlled to display the second gray scale, and when the first sub-display area displays the first gray scale and the second sub-display area displays the second gray scale, the target gray scale is displayed in the display area.
In the above embodiments, the target gray scale may be between the first gray scale and the second gray scale, for example, the target gray scale is 3, the first gray scale may be 2, and the second gray scale may be 4.
Of course, the first gray level can be higher than the second gray level, such as the first gray level is 4 and the second gray level is 2. The ratio of the number of gray scales to be displayed in the target gray scale display mode to the number of gray scales to be displayed in the current gray scale display mode may be 2:1 or 3:1 (the ratio is merely an exemplary illustration, and the ratio of the two is not limited in the present invention).
For example, if the ratio of the two gray scales is 2:1, for example, if the number of gray scales to be displayed in the current gray scale display mode is 0 to 20 gray scales, the number of gray scales required in the target gray scale is 0 to 40 gray scales, i.e., the display of 0 to 20 gray scales is expanded to 0 to 40 gray scales, i.e., 1 gray scale to be processed can be inserted into every two gray scales. The schematic diagram of the correspondence relationship between the expanded gray levels can be seen in FIG. 3. As shown in FIG. 3, the expanded L0/L2/L4/L6 … … L38/L40 directly corresponds to the data display before expansion. Wherein, the expanded L1/L3/L5 … … L37/L39 gray scale needs to be processed. It should be noted that, expanding the display of the gray scales from 0 to 20 to the gray scales from 0 to 40 is only an exemplary illustration, and may also convert 20 gray data into finer 60 or 80 gray data (the specific numerical value may be determined according to the display requirement), and only needs to mix and display the pixel modules with the appropriate number at the appropriate different gray scales, which is not limited specifically herein.
In the above embodiment, the LEDs emitting light may be distributed in the same pixel, and in addition, in order to make the gray scale distribution more uniform, the LEDs may also be distributed in a plurality of different pixel, that is, the red LEDs, the green LEDs, and the blue LEDs included in each group of RGB in the first sub-display region. The RGB LEDs in the first sub-display region may be formed by LEDs distributed in a plurality of pixel points, for example, a group of RGB LEDs in the first sub-display region may be distributed in two pixel points, specifically, for example: the red LED (R LED) is positioned in one pixel point, the green LED (G LED) and the blue LED (B LED) are positioned in the other pixel point, or the red LED and the green LED are positioned in one pixel point, the blue LED is positioned in the other pixel point, or the red LED and the blue LED are positioned in one pixel point, and the green LED is positioned in the other pixel point.
In addition, a set of RGB can also be distributed in three pixel points respectively, that is, the red LED is located in one pixel point, the green LED is located in one pixel point and the blue LED is located in one pixel point, and the three pixel points are different from each other. Likewise, the RGB groups in the second sub-display region may be distributed in the distribution manner described above.
Alternatively, referring to fig. 4, as shown in fig. 4, the display area may be divided into A, B, C, D, E, F six areas, i.e. 6 display areas, each of which includes a first sub-display area and a second sub-display area. For example, in the a display region, the a display region includes two pixels, and the two pixels are RGB LEDs arranged in rows, respectively. At this time, the first sub-display region is a region formed by the black LED in fig. 4, wherein the black LED is used for displaying the first gray scale; the second sub-display area is an area formed by the white LEDs in fig. 4, and the white LEDs are used for displaying a second gray scale.
Of course, it is also possible that the LED showing black in FIG. 4 is used for displaying the first gray scale and the LED showing white in FIG. 4 is used for displaying the second gray scale. Here, the number of the carbon atoms is not particularly limited.
It should be noted that, a plurality of pixels may also be divided into a region, for example, 4 pixels are divided into a region, 9 pixels are divided into a region, and the like, where a group of RGB displaying the same gray scale may be distributed among the plurality of pixels in the region. Here, the number of the carbon atoms is not particularly limited.
For example, the main body of the above steps may be a sending card or a receiving card or other processors or modules with related processing capabilities.
In the method, after the target gray scale to be displayed in the display area is determined, the first gray scale and the second gray scale corresponding to the target gray scale are obtained, the first sub-display area in the display area is controlled to display the first gray scale, and the second sub-display area in the display area is controlled to display the second gray scale, so that the target gray scale is displayed in the display area.
In one exemplary embodiment, controlling a first sub-display region of the display regions to display the first gray scale and controlling a second sub-display region of the display regions to display the second gray scale includes: determining a first current for displaying the first gray scale and a second current for displaying the second gray scale; outputting the first current to the first group of RGB light-emitting diodes included in the first sub-display region so that the first group of RGB light-emitting diodes display the first gray scale; and outputting the second current to the second group of RGB light-emitting diodes included in the second sub-display area so that the second group of RGB light-emitting diodes display the second gray scale.
Continuing with the example of FIG. 4, A, B, C, D, E, F the six display regions include a first sub-display region and a second sub-display region, respectively. At this time, for the display after the expansion, when the L1 gray scale needs to be displayed, 1 group of RGB light emitting diodes in the first sub-display region are lit with the current of the L0 gray scale (wherein, the RGB light emitting diodes may not be the LEDs of the same pixel), and 1 group of RGB light emitting diodes in the second sub-display region are lit with the current of the L2 gray scale. When the gray scale of L3 needs to be displayed, the current of the gray scale of L2 lights up 1 group of RGB light-emitting diodes in the first sub-display region, the current of the gray scale of L4 lights up 1 group of RGB light-emitting diodes in the second sub-display region, and so on, thereby converting the image data signal of L1/L3/L5 … … L37/L39 input at the front end into a new data signal. Therefore, the mode that the refresh rate needs to be reduced when gray scale expansion is carried out is avoided, the black stripe phenomenon which occurs when the PM-Mini LED display frame rate is reduced is solved, and the display quality is improved.
In an exemplary embodiment, the obtaining the first gray scale and the second gray scale corresponding to the target gray scale includes: acquiring configuration information, wherein the configuration information comprises a gray scale corresponding relation in the display area; and analyzing the configuration information to determine the first gray scale and the second gray scale corresponding to the target gray scale from the configuration information. In this embodiment, the corresponding relationship between the target gray scale and the first gray scale and the second gray scale can be confirmed by analyzing the acquired configuration information. The current gray scale display method of the display area can also be determined by the configured performance parameters. The gray scale corresponding relationship in the display area included in the configuration information may be preset.
In one exemplary embodiment, the gray-scale correspondence includes: the number of orders corresponding to the target gray scale is equal to the average value of the sum of the number of orders of the first gray scale and the number of orders of the second gray scale. In this embodiment, the order corresponding to the target gray scale may be an average value of a sum of the order corresponding to the first gray scale and the order corresponding to the second gray scale, for example, when the target gray scale is 3, the order corresponding to the first gray scale may be 2, the order corresponding to the second gray scale may be 4, and an average value of the sum of the two is the order 3 corresponding to the target gray scale.
In one exemplary embodiment, the light emitting diode comprises a passive micro diode. In this embodiment, the PM-Mini LED direct display and backlight product can be used to improve the display effect of the PM-Mini LED at the low frame rate.
In an exemplary embodiment, the first number of the first group of RGB light emitting diodes and the second number of the second group of RGB light emitting diodes are light emitting diodes within a common cathode or common anode scan drive architecture.
In the present embodiment, the RGB LEDs are suitable for the current-driven architecture of the PM-Mini LEDs sharing a common cathode or a common anode.
In an exemplary embodiment, the at least two pixels comprise a first pixel and a second pixel; the first pixel point comprises a first red light-emitting diode, a first green light-emitting diode and a first blue light-emitting diode; the second pixel point comprises a second red light-emitting diode, a second green light-emitting diode and a second blue light-emitting diode.
In this embodiment, the first pixel point and the second pixel point may respectively include a part of the light emitting diodes in the group of RGB light emitting diodes, that is, the first pixel point may respectively include a part of the light emitting diodes in a red light emitting diode, a green light emitting diode, and a blue light emitting diode included in the group of RGB light emitting diodes, and the second pixel point includes another part of the light emitting diodes.
That is, the RGB light emitting diode refers to a three-color LED including a red light emitting diode (i.e., R LED), a green light emitting diode (G LED), and a blue light emitting diode (B LED).
In one exemplary embodiment, the first set of RGB light emitting diodes includes the first red LED and the second green LED and the second blue LED. In this embodiment, the red LEDs, the green LEDs and the blue LEDs included in one group of RGB LEDs may be respectively located in different pixel points. For example, a red LED may be located in the first pixel, a green LED may be located in the second pixel, and a blue LED may be located in the second pixel. Of course, the red LED may also be located in the second pixel, the green LED may also be located in the first pixel, the blue LED may also be located in the first pixel, or the red LED and the green LED may be located in the first pixel, the blue LED is located in the second pixel, and so on. That is, a group of RGB leds included in each sub-display region emits light, and the group of RGB leds may be located in different pixel points of the sub-display region.
In the embodiment, the black stripe phenomenon generated when the display frame rate of the PM-Mini LED is reduced is solved, and the display quality is improved. More gray level display of the PM-Mini LED is realized, the display is excessively fine and smooth, and the display quality is improved.
