[0048] Furthermore, an embodiment of the present invention provides a method for adjusting the backlight brightness of a display device, referring to Figure 2 , Figure 2The figure is a flow chart of a first embodiment of a method for adjusting backlight brightness of a display device according to the present invention.

[0049] In this embodiment, the method for adjusting the backlight brightness of a display device of the present invention may include:

[0050] Step S10: obtaining an output image including a video playing area and a non-video playing area;

[0051] In this embodiment, when the display device is running, the display device obtains an output image including a video playback area and a non-video playback area through an internally integrated system chip.

[0052] Exemplarily, for example, when the display enters the operation process, the output image containing the video playback area and the non-video playback area is obtained by the register in the local dimming function module in the SOC (System on Chip) chip built into the display.

[0053] Step S20: determining a first backlight partition corresponding to the video playback area according to the output image;

[0054] In this embodiment, the display device determines the backlight partition of the display device covered by the position of the video playback area in the output image through the system chip according to the output image, and marks the backlight partition as the first backlight partition corresponding to the video playback area.

[0055] Exemplarily, for example, the display partitions the above-mentioned output image according to the partition parameters pre-set by the user in the above-mentioned local dimming function module to determine the backlight partition of the display covered by the position of the video playback area in the output image, and marks the backlight partition as the first backlight partition corresponding to the video playback area.

[0056] Furthermore, in a feasible embodiment, the above step S20 may specifically include:

[0057] Step S201: obtaining coordinates of each vertex of the video playback area in the output image;

[0058] In this embodiment, the display device obtains the starting point coordinates of the playback window preset by the user and the size data of the playback window, and processes the starting point coordinates and the size data through a brightness data processing module configured in the display device, thereby obtaining the coordinates of each vertex of the playback window preset by the user on the display device.

[0059] Step S202: determining a first backlight partition corresponding to the video playback area according to the vertex coordinates.

[0060] In this embodiment, the display device encloses the coordinates of each vertex according to the coordinates of each point of the playback window on the display device, thereby obtaining the backlight partition of the display device covered in the playback window area after enclosing, and determines the backlight partition as the first backlight partition corresponding to the above-mentioned video playback area.

[0061] Exemplarily, for example, the display first obtains the starting coordinates of the playback window preset by the user in the application layer as (100, 200) and the size data of the playback window as 480*270. Then, the display processes the starting coordinates and the size data through a small window data processing module configured in the display, thereby obtaining the vertex coordinates of the playback window preset by the user in the application layer as (100, 200), (580, 200), (100, 470), and (580, 470). Finally, the display encloses the previous vertex coordinates, and then obtains 18 partitions 81, 82, 83, 84, 85, 86, 121, 122, 123, 124, 125, 126, 161, 162, 163, 164, 165, and 166 of the display covered in the playback window area after encirclement, and determines them as the first backlight partitions corresponding to the video playback area.

[0062] It should be noted that, in this embodiment, the backlight lamps used in the above display are divided into 40*20 zones (40 columns and 20 rows of lamps).

[0063] Step S30: acquiring first backlight control data of the first backlight partition, and adjusting the first backlight control data according to a preset backlight ratio;

[0064] In this embodiment, the display device obtains various backlight data in the output image through the system chip, and obtains the first backlight control data of the first backlight partition based on the various backlight data. The display device adjusts the first backlight control data according to the backlight ratio preset by the user through the brightness data processing module.

[0065] Exemplarily, for example, the display uses the statistical function preset in the register in the local dimming function module to obtain the RGB value or YUV value in the output image and perform histogram statistics. At the same time, the display obtains the grayscale value data of the output image through the additional thread preset in the SOC chip. Thereafter, the local dimming function module obtains the backlight control data of the output image as a whole by calculating the backlight data and the grayscale value data. The display classifies the backlight control data according to the video playback area and the non-video playback area in the output image through the small window data processing module to obtain the first backlight control data corresponding to the first backlight partition. Finally, the display adjusts the first backlight control data according to the backlight ratio preset by the user through the small window data processing module.

[0066] Furthermore, in a feasible embodiment, the above step S30 may specifically include:

[0067] Step S301: acquiring backlight data of the output image, and converting the backlight data to obtain backlight control data of the output image;

[0068] In this embodiment, the display device obtains each item of backlight data in the output image through the system chip, and converts each item of backlight data into the backlight control data through a statistical function preset in the system chip.

[0069] Step S302: Classify the backlight control data according to the video playback area to obtain first backlight control data of the first backlight partition corresponding to the video playback area.

[0070] In this embodiment, the display device classifies the output image according to the video playback area and non-video playback area according to the backlight control data of the entire output image through the brightness data processing module in the display device to obtain the first backlight control data of the first backlight partition corresponding to the video playback area.

[0071] Exemplarily, for example, the display uses the statistical function preset in the register in the local dimming function module to obtain the RGB value and YUV value in the output image and perform histogram statistics. At the same time, the display obtains the grayscale value data of the output image through the additional thread preset in the SOC chip, and calculates the histogram statistical result and the grayscale value data through the local dimming function to obtain the backlight control data of the output image. After that, the display classifies the video playback area and the non-video playback area in the output image according to the backlight control data through the small window data processing module in the display, so as to obtain the first backlight control data of the first backlight partition corresponding to the video playback area.

[0072] Furthermore, in a feasible embodiment, the above step S301 may specifically include:

[0073] Calling the original thread to obtain backlight data of the fixed screen display area in the output image;

[0074] Call a preset new thread to obtain backlight data of the video playback area in the output image.

[0075] In this embodiment, when the display device obtains the output image of the fixed screen display area, the backlight data of the output image is collected through the normal working thread of the processor in the display. Once the display has a video signal output, the backlight data of the video playback area in the output image is obtained through an additional thread preset by the processor.

[0076] Exemplarily, for example, when the display has no video signal output, the display only collects the overall output image through the local dimming function module. When the local dimming function module detects that the display has video signal output, the backlight data of the video playback area in the output image is obtained through the additional thread preset by the local dimming function module.

[0077] Step S40: adjusting the backlight brightness of the display device according to the adjusted first backlight control data, so that the first backlight brightness of the video playback area is higher than the second backlight brightness of the non-video playback area.

[0078] In this embodiment, the display device adjusts the brightness of the display device according to the adjusted first backlight control data through a backlight control module configured in the display device, so that the first backlight brightness in the video playback area in the output image is adjusted to be higher than the second backlight brightness in the non-video playback area in the output image according to the first backlight control data.

[0079] Exemplarily, for example, the display packages the adjusted first backlight control data and sends it to the backlight control chip configured in the display through the SPI bus, so that the backlight control chip adjusts the backlight brightness of the display according to the received first backlight control data, so that the first backlight brightness of the video playback area is adjusted to be higher than the second backlight brightness according to the first backlight control data.

[0080] Furthermore, in a feasible embodiment, the above step S40 may specifically include:

[0081] Step S401: transmitting the adjusted first backlight control data to the backlight control chip of the display device, so that the backlight control chip adjusts the backlight brightness of the video playback area to a first backlight brightness that is higher than the second backlight brightness of the non-video playback area according to the adjusted first backlight control data.

[0082] Exemplarily, for example, the display packages the adjusted first backlight control data and sends the data to the backlight control chip configured in the display through the SPI bus, so that the backlight control chip adjusts the backlight brightness of the video playback area in the output image according to the first backlight control data after receiving the first backlight control data through the SPI bus, and makes the backlight brightness a first backlight brightness that is higher than the second backlight brightness of the non-video playback area.

[0083] Furthermore, in a feasible embodiment, the method for adjusting the backlight brightness of a display device of the present invention further includes:

[0084] Step S50: determining a second backlight partition corresponding to the non-video playback area according to the output image;

[0085] In this embodiment, the display device determines the backlight partition of the display device covered by the non-video playback area in the output image through the system chip based on the output image, and marks the backlight partition as the second backlight partition corresponding to the non-video playback area.

[0086] Exemplarily, for example, the display partitions the output image according to the partition parameters preset by the user in the local dimming function module to determine the backlight partition of the display covered by the non-video playback area in the output image, and marks the backlight partition as the second backlight partition corresponding to the non-video playback area.

[0087] Step S60: acquiring second backlight control data of the second backlight partition, and adjusting the second backlight control data according to a preset backlight ratio;

[0088] In this embodiment, the display device obtains various backlight data in the output image through the system chip, and obtains the second backlight control data of the second backlight partition based on the various backlight data. The display device adjusts the second backlight control data according to the backlight ratio preset by the user through the brightness data processing module.

[0089] Exemplarily, for example, the display uses the statistical function preset in the register in the local dimming function module to obtain the RGB value or YUV value in the output image and perform histogram statistics. At the same time, the display obtains the grayscale value data of the output image through the additional thread preset in the SOC chip. After that, the local dimming function module obtains the backlight control data of the output image as a whole by calculating the backlight data and the grayscale value data. After that, the display classifies the backlight control data according to the video playback area and the non-video playback area in the output image through the small window data processing module to obtain the second backlight control data corresponding to the second backlight partition. Finally, the display adjusts the second backlight control data according to the backlight ratio preset by the user through the small window data processing module.

[0090] Step S70: adjusting the backlight brightness of the display device according to the adjusted first backlight control data and the adjusted second backlight control data, so that the first backlight brightness of the video playback area is higher than the second backlight brightness of the non-video playback area.

[0091] In this embodiment, the display device adjusts the backlight brightness of the video playback area to the first backlight brightness according to the above-mentioned adjusted first backlight control data and the above-mentioned adjusted second backlight control data through a backlight control module configured in the display device according to the first backlight control data, and adjusts the backlight brightness of the non-video playback area to the second backlight brightness according to the second backlight control data, wherein the first backlight brightness is higher than the second backlight brightness.

[0092] Furthermore, in a feasible embodiment, the above step S70 specifically includes:

[0093] Step S701: passing the adjusted first backlight control data and the adjusted second backlight control data to the backlight control chip of the display device, so that the backlight control chip adjusts the backlight brightness of the video playback area to the first backlight brightness according to the adjusted first backlight control data, and adjusts the backlight brightness of the non-video playback area to the second backlight brightness according to the adjusted second backlight control data, wherein the first backlight brightness is higher than the second backlight brightness

[0094] Exemplarily, for example, the display packages the adjusted first backlight control data and the adjusted second backlight control data, and sends the data to the backlight control chip configured in the display through the SPI bus, so that the backlight control chip adjusts the backlight brightness of the video playback area to the first backlight brightness and adjusts the backlight brightness of the non-video playback area to the second backlight brightness after receiving the first backlight control data and the second backlight control data, and makes the first backlight brightness higher than the second backlight brightness.

[0095] In this embodiment, first, during the operation of the display device, the display device obtains an output image including a video playback area and a non-video playback area through an internally integrated system chip. Then, based on the above output image, the display device determines the backlight partition of the display device covered by the position of the video playback area in the output image through the internally integrated system chip, and marks the backlight partition as a first backlight partition. Then, the display device obtains various backlight data in the above output image through the internally integrated system chip. The display device obtains first backlight control data of the above first backlight partition based on the various backlight data, and the display device adjusts the first backlight control data according to the backlight ratio preset by the user. Finally, the display device adjusts the brightness of the display device according to the adjusted first backlight control data, so that the first backlight brightness in the video playback area in the above output image is higher than the second backlight brightness in the non-video playback area in the output image.

[0096] Compared with the existing display method of uniformly adjusting the backlight brightness of the entire display area of ​​the display that simultaneously outputs video images and fixed images, the present invention adjusts the backlight brightness of the video playback area and the output non-video playback area in the output image of the display separately, thereby highlighting the playback effect of the video playback area and improving the image contrast, making the playback image in the video playback area more prominent.

[0097] For further information, please refer to Figure 4 , a preferred embodiment of the method for adjusting the backlight brightness of a display device of the present invention is proposed. In this embodiment, the display device executes the application process described below according to the backlight brightness adjustment method, and adjusts the backlight brightness of the video playback area and the output non-video playback area in the output screen of the display, respectively, so as to achieve the effect of highlighting the playback effect of the video playback area and improving the picture contrast, so that the playback picture in the video playback area is more prominent.

[0098] In this embodiment, during the operation of the display, the SOC chip in the display obtains an output image including a video playback area and a non-video playback area through a register in a local dimming function module in the chip, and partitions each frame of the output image according to the output image through a partition parameter preset in the local dimming function module, so as to determine that the backlight partition of the display covered by the position of the video playback area in the output image is the first backlight partition, and the backlight partition of the display covered by the position of the non-video playback area in the output image is the second backlight partition, and then the display is configured to be a backlight partition of the display according to the local dimming function module. The registers in the dimming function module are used to obtain the RGB value or YUV value of each frame of the above-mentioned output image and perform histogram statistics to obtain the backlight data of each frame of the output image, and when the display is running in the above-mentioned SOC chip, the grayscale value data of each frame of the above-mentioned output image is obtained through the additional thread preset by the SOC chip. At the same time, the display calculates the first backlight control data corresponding to the first backlight partition and the second backlight control data corresponding to the second backlight partition according to the backlight data of the above-mentioned output image and the grayscale value data of the above-mentioned output image through the above-mentioned localdimming function module. The display obtains the starting point coordinates of the playback window preset by the user in the application layer and the size data of the playback window, and processes the starting point coordinates and the size data through the small window data processing module configured in the display to obtain the coordinates of each vertex of the playback window preset by the user in the application layer and the position of the playback window in the overall display area of ​​the display. The display is processed by the above-mentioned small window data processing module The coordinates of the above-mentioned playback window are enclosed, and the backlight partition in the display covered by the playback window after the enclosed is extracted to determine the first backlight partition corresponding to the above-mentioned video playback area. The display classifies the backlight control data according to the video playback area and the non-video playback area through the above-mentioned small window data processing module to obtain the first backlight control data of the video playback area and the second backlight control data of the non-video playback area, and increases the first backlight control data according to a preset ratio and adds a brightening mark to the first backlight control data, so as to amplify the improvement effect of the first backlight brightness. Finally, the display packages the adjusted first backlight brightness control data and the second backlight control data, and sends them to the backlight control chip configured in the display through the SPI bus, so that the backlight control chip adjusts the first backlight brightness of the above-mentioned first backlight partition according to the first backlight control data, and adjusts the second backlight brightness of the second backlight partition according to the second backlight control data, so that the first backlight brightness is higher than the second backlight brightness.
