[0068] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0069] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0070] Figure 1 It is a structural schematic diagram of a display device involved in an embodiment of the present application. The display device 10 may include a control component 11, a display panel controller 12 and a display panel 13. Multiple lines S are connected between the control component 11 and the display panel controller 12, and the display panel controller 12 is electrically connected to the display panel 13.

[0071] Among them, the multiple lines can be lines of the interface between the control component 11 and the display panel controller 12. Exemplarily, the interface between the control component 11 and the display panel controller 12 may include a general-purpose input / output (GPIO), and the multiple lines S may include multiple functional lines and multiple redundant lines, wherein the functional lines are lines that have been set with corresponding functions and are used to transmit various data, such as data for realizing image display functions. The redundant lines are lines that are not set with specific functions.

[0072] The control component 11 can control the display panel controller 12 through the line between the control component 11 and the display panel controller 12 to realize the image display function. The control component 11 may include one or more processors in the display device.

[0073] The display panel controller 12 can control the display panel 13 under the control of the control component 11 so that the display panel displays images. The display panel controller 12 may include a logic board (TCON), which is also called a screen driving board or a central control board, and can be used to control the display panel.

[0074] In addition, the display device further includes a backlight assembly 14, the display panel 13 includes a display surface m1, and a back surface m2 opposite to the display surface m1, and the backlight assembly 14 is located on the back surface m2 of the display panel 13. The backlight assembly 14 can be used to provide light to the display panel 13. Exemplarily, the backlight assembly 14 can provide light of different intensities to different areas to achieve a high dynamic range image (High-Dynamic Range, HDR) function. Compared with before startup, after the HDR function is started, more dynamic range and image details can be provided, and the user experience is better.

[0075] The maximum brightness of HDR 1000 (an HDR standard) and HDR1400 (an HDR standard) will reach 1000 nits and 1400 nits respectively, which will cause great harm to human eyes if used for a long time. The local dimming function is a function used to implement HDR, but in current display devices, there is usually no separate control function for the local dimming function and the brightness display function.

[0076] Figure 2 is a method flow chart of a control method of a display device provided in an embodiment of the present application, for Figure 1 The control component in the display device shown, the control method of the display device includes:

[0077] Step 201: Acquire control information, where the control information is used to control at least one of a backlight zone dimming function and a brightness limiting function.

[0078] Step 202: Process the control information into control information in a target format.

[0079] Step 203: Send control information in a target format to the display panel controller through at least one preset line among the multiple lines.

[0080] Among them, the control information can control the turning on and off of the backlight zone dimming function. After the brightness limiting function is turned on, it can limit the maximum brightness of the display device to avoid excessive brightness that hurts the human eye.

[0081] In summary, the control method of the display device provided in the embodiment of the present application processes the received control information for controlling at least one of the backlight zone dimming function and the brightness limiting function through the control component, and sends the processed control information to the display panel controller through at least one preset line among multiple lines between the display panel controller, so that the display panel controller controls the display panel to realize the control of at least one of the backlight zone dimming function and the brightness limiting function, so that the control component can have more functions, which solves the problem of the relatively single function of the control component in the related art and achieves the effect of enriching the function of the control component.

[0082] In addition, the control method can turn off the backlight zone dimming function and the brightness limiting function to limit the maximum brightness of the display device, avoid excessive brightness damaging the human eye, improve the protection effect on users, and provide a better user experience.

[0083] Figure 3 is a method flow chart of another method for controlling a display device provided in an embodiment of the present application, for Figure 1 The control component in the display device shown, the control method of the display device includes:

[0084] Step 301: Acquire control information, where the control information is used to control at least one of a backlight zone dimming function and a brightness limiting function.

[0085] The control component can obtain the control information from the outside world. For example, the control information can be sent to the control component by an external controller. The controller can be a control device corresponding to the display device, or it can be a terminal (such as a smart device such as a smartphone) installed with an application corresponding to the display device.

[0086] In addition, the control component can also obtain the control information through other structures in the display device. For example, the display device also includes a control button (which can be a physical button or a virtual button). When the control button is triggered, the control information can be sent to the control component.

[0087] In the embodiment of the present application, the control information is used to control the backlight zone dimming function and the brightness limiting function as an example for explanation, but this is not limited to this.

[0088] Step 302: Process the control information into control information in a target format.

[0089] Based on different transmission methods, the target form may also be different. In the embodiment of the present application, the control information in the target form may be control information of different levels.

[0090] In an exemplary embodiment, step 302 may include:

[0091] 1) Processing control information as a signal of a first level or a signal of a second level as first information.

[0092] The first level is higher than the second level, one of the first level signal and the second level signal is used to indicate the opening of a function, and the other signal is used to indicate the closing of a function. The first level is a high level signal relative to the second level, and the second level is a low level signal relative to the first level.

[0093] In an exemplary embodiment, a high-level signal can be used to indicate the activation of a function, and a low-level signal can be used to indicate the deactivation of a function. The first information is information for controlling the backlight zone dimming function. If the control information indicates the activation of the backlight zone dimming function, the control component can process the control information into a signal of the first level; if the control information indicates the deactivation of the backlight zone dimming function, the control component can process the control information into a signal of the second level.

[0094] 2) Processing the control information into a first level signal or a second level signal as the second information

[0095] The first level is higher than the second level, and one of the first level signal and the second level signal is used to indicate the opening of a function, and the other signal is used to indicate the closing of a function. The first level is a high level signal relative to the second level, and the second level is a low level signal relative to the first level.

[0096] In an exemplary embodiment, a high-level signal can be used to indicate the activation of a function, and a low-level signal can be used to indicate the deactivation of a function. The second information is information for controlling the brightness limiting function. If the control information indicates the activation of the brightness limiting function, the control component can process the control information into a signal of a first level; if the control information indicates the deactivation of the brightness limiting function, the control component can process the control information into a signal of a second level.

[0097] The multiple lines connected between the control component and the display panel controller include multiple functional lines and at least two redundant lines, and the at least two redundant lines include a first line and a second line. That is, the control component can send control signals for the brightness limiting function and the zone dimming control respectively through the two redundant lines. This will not affect the realization of other functions, and there is no need to adjust the existing structure and control process, which is convenient and quick.

[0098] In an exemplary embodiment, please refer to Figure 1 The first line may be line 23, the second line may be line 25, line 23 may be a line connected to the STV2 interface, and line 25 may be a line connected to the CPV interface. Both lines are redundant lines and are connected to redundant interfaces.

[0099] Step 303: Send first information to the display panel controller through the first line.

[0100] The control component can send the first information to the display panel controller through the first line as a redundant line, and there is no need to adjust the functions of other lines, so the control of the backlight zone dimming function can be realized conveniently and quickly.

[0101] Step 304: Send second information to the display panel controller through a second line.

[0102] The control component can send the second information to the display panel controller through the second line serving as a redundant line, without adjusting the functions of other lines, and can conveniently and quickly implement the control of the brightness limiting function.

[0103] It should be noted that the embodiment of the present application does not limit the execution order of step 303 and step 304. For example, step 304 can be executed first, and then step 303, or step 303 and step 304 can be executed at the same time. The embodiment of the present application does not limit this.

[0104] Step 305: After a predetermined period of time, control the backlight assembly to restart.

[0105] After the control component sends the first information and the second information to the display panel controller, the display panel controller will change the control mode for the display panel and the backlight component, and the corresponding control algorithm will also change. In order to adapt to the changed control mode and control algorithm, the control component can restart the backlight module, and it can avoid that the brightness of the display device changes too much. The predetermined time length can be used as a buffer time for the display panel controller to switch the control mode and algorithm. Exemplarily, the predetermined time length is greater than or equal to 100 milliseconds.

[0106] It should be noted that the control component can control the backlight component to restart after a predetermined time period after both the first information and the second information are sent.

[0107] Please refer to Figure 4 , Figure 4 It is a timing diagram in an embodiment of the present application, which includes the potential timing L1 of the backlight module and the timing L2 of the control component sending the signal. It can be seen that after the timing L2 of sending the signal is pulled up for the preset time length d1, the potential timing L1 of the backlight module is pulled down to turn off the backlight module. At time t1, the backlight module starts and completes the restart. Then at time t2, the control component sends the first information and the second information to the display panel controller, wherein the second information can be used to indicate the activation of the brightness limiting function, and then at time t3 after the preset time length d1 after time t2, the potential timing L1 of the backlight module is pulled down again to turn off the backlight module.

[0108] Step 305 may be performed in two ways:

[0109] The first method is: the control component sends a control signal to the display panel controller so that the display panel controller controls the backlight component to restart based on the control signal; in this control method, the display panel controller can forward the control signal to restart the backlight component.

[0110] The second method: the control component sends a control signal to the backlight component to control the backlight component to restart. In this method, the control component can directly send a control signal to the backlight component to control the backlight component to restart.

[0111] In summary, the control method of the display device provided in the embodiment of the present application processes the received control information for controlling at least one of the backlight zone dimming function and the brightness limiting function through the control component, and sends the processed control information to the display panel controller through at least one preset line among multiple lines between the display panel controller, so that the display panel controller controls the display panel to realize the control of at least one of the backlight zone dimming function and the brightness limiting function, so that the control component can have more functions, which solves the problem of the relatively single function of the control component in the related art and achieves the effect of enriching the function of the control component.

[0112] In addition, the control method can turn off the backlight zone dimming function and the brightness limiting function to limit the maximum brightness of the display device, avoid excessive brightness damaging the human eye, improve the protection effect on users, and provide a better user experience.

[0113] Figure 5 is a method flow chart of another method for controlling a display device provided in an embodiment of the present application, for Figure 1 The control component in the display device shown, the control method of the display device includes:

[0114] Step 401: Acquire control information, where the control information is used to control at least one of a backlight zone dimming function and a brightness limiting function.

[0115] The control component can obtain the control information from the outside world. For example, the control information can be sent to the control component by an external controller. The controller can be a control device corresponding to the display device, or it can be a terminal (such as a smart device such as a smartphone) installed with an application corresponding to the display device.

[0116] In addition, the control component can also obtain the control information through other structures in the display device. For example, the display device also includes a control button (which can be a physical button or a virtual button). When the control button is triggered, the control information can be sent to the control component.

[0117] In the embodiment of the present application, the control information is used to control the backlight zone dimming function and the brightness limiting function as an example for explanation, but this is not limited to this.

[0118] Step 402: Process the control information into control information in a target format.

[0119] Based on the different sending modes, the target form will also be different. In the embodiment of the present application, the control information of the target form can be sent to the display panel controller through the target line. The target line can include two lines, such as Figure 1 As shown, the target line may include lines corresponding to interface 1 (Pin1) and interface 34 (Pin34) in the I2C interface (the I2C interface requires a rate of 100 kHz and a pull-up voltage of 1.8 volts) (interface 1 may be an I2C_CLK interface, and interface 34 may be an I2C_DATA interface). The control information in the target form may include at least two binary bits. Based on the requirements of the I2C protocol, other information may be sent to the display panel controller along with the control information, and the other information may also include two binary bits.

[0120] Exemplarily, the information represented by the multi-dimensional binary data in the target-format control information may be as shown in Table 1:

[0121] Table 1

[0122]

[0123]

[0124] Among them, the first information and other information can occupy different binary bits respectively. For example, the information transmitted by the lines corresponding to the two interfaces Pin1 and Pin24 can be 0xXXXX, where the first and second bits from the right are binary bits that can be occupied by the first information, and the third and fourth bits are binary bits occupied by other information.

[0125] In addition, the control component can also transmit control information in a target form through other lines. For example, the register address can be specified through DPCD, and the control information in a target form can be transmitted through the AUX channel to achieve control of the backlight zone dimming function and the brightness limiting function.

[0126] Step 403: Send control information in a target format to the display panel controller via a target line among the multiple lines.

[0127] After acquiring the control information in the target form, the control component can send the control information in the target form to the display panel controller through the target line. For example, the control information in the target form can be sent to the display panel controller through the lines corresponding to the two interfaces Pin1 and Pin24 in the I2C interface.

[0128] Step 404: After a predetermined period of time, control the backlight assembly to restart.

[0129] After the control component sends the control information in the target form to the display panel controller, the display panel controller will change the control mode for the display panel and the backlight component, and the corresponding control algorithm will also change. In order to adapt to the changed control mode and control algorithm, the control component can restart the backlight module. The predetermined time length can be used as a buffer time for the display panel controller to convert the control mode and algorithm. Exemplarily, the predetermined time length ranges from 80 milliseconds to 120 milliseconds. In an exemplary embodiment, the predetermined time length is 100 milliseconds.

[0130] Step 405 may be performed in two ways:

[0131] The first method is: the control component sends a control signal to the display panel controller so that the display panel controller controls the backlight component to restart based on the control signal; in this control method, the display panel controller can forward the control signal to restart the backlight component.

[0132] The second method: the control component sends a control signal to the backlight component to control the backlight component to restart. In this method, the control component can directly send a control signal to the backlight component to control the backlight component to restart.

[0133] In summary, the control method of the display device provided in the embodiment of the present application processes the received control information for controlling at least one of the backlight zone dimming function and the brightness limiting function through the control component, and sends the processed control information to the display panel controller through at least one preset line among multiple lines between the display panel controller, so that the display panel controller controls the display panel to realize the control of at least one of the backlight zone dimming function and the brightness limiting function, so that the control component can have more functions, which solves the problem of the relatively single function of the control component in the related art and achieves the effect of enriching the function of the control component.

[0134] In addition, the control method can turn off the backlight zone dimming function and the brightness limiting function to limit the maximum brightness of the display device, avoid excessive brightness damaging the human eye, improve the protection effect on users, and provide a better user experience.
