Currently, HDMI (high definition multimedia interface, high-definition multimedia interface) has been widely used for display devices such as televisions. HDMI is a digital video/audio interface technology that can transmit both audio and video signals.

The HDMI device may input a high-brush signal of different frequencies, such as a high-brush signal of 120HZ (heretz, HZ), or a high-brush signal of 144HZ, or a high-brush signal of 240HZ, to a display device such as a television.

The display screen parameters of the display device can be the display screen parameters corresponding to the high-brushing signals with different frequencies, so that the definition and smoothness of the pictures displayed by the display device are ensured. For example, when the display screen parameter of the display device is the display screen parameter corresponding to the 120HZ high-brush signal, the display device may receive and display the 120HZ high-brush signal input by the HDMI device, when the display screen parameter of the display device is the display screen parameter corresponding to 144HZ, the display device may receive and display the 144HZ high-brush signal input by the HDMI device, and when the display screen parameter of the display device is the display screen parameter corresponding to 240HZ, the display device may receive and display the 240HZ high-brush signal input by the HDMI device.

However, the display parameters of the current display device cannot be converted with each other, which results in that the display device cannot support high-brush signals of multiple frequencies (such as 120HZ, 144HZ and 240 HZ) at the same time.

In order to fully adapt to the high-end requirements of users on electronic contest games, sports events and high-speed blue-ray films, thereby bringing clear, smooth and comfortable perfect visual feast, the HDMI device can input timing signals with different frequencies, namely high-brush signals, such as high-brush signals of 120 hertz (heretz, HZ), or high-brush signals of 144HZ, or high-brush signals of 240HZ, to display devices such as televisions and the like through HDMI channels.

The display screen parameters (also called as screen parameters) of the display device can be display screen parameters corresponding to high-brushing signals with different frequencies, so that the definition and smoothness of pictures displayed by the display device are ensured. For example, when the display screen parameter of the display device is the display screen parameter corresponding to the 120HZ high-brush signal, the display device may receive and display the 120HZ high-brush signal input by the HDMI device, when the display screen parameter of the display device is the display screen parameter corresponding to 144HZ, the display device may receive and display the 144HZ high-brush signal input by the HDMI device, and when the display screen parameter of the display device is the display screen parameter corresponding to 240HZ, the display device may receive and display the 240HZ high-brush signal input by the HDMI device.

However, the display parameters of the current display device cannot be converted with each other, which results in that the display device cannot support high-brush signals of multiple frequencies (such as 120HZ, 144HZ and 240 HZ) at the same time. That is, the current display device does not concentrate the high-brush signals with multiple frequencies (such as 120HZ, 144HZ and 240 HZ) on one display device, but the high-brush signals with multiple frequencies (such as 120HZ, 144HZ and 240 HZ) are concentrated on one display device, so that three scenes in which the timing signals are switched back and forth exist.

Currently, some display devices can switch from a high-brush signal of 120HZ to a high-brush signal of 240HZ, or switch from a high-brush signal of 144HZ to a high-brush signal of 240HZ, that is, the display device can convert a display screen parameter corresponding to the high-brush signal of 120HZ into a corresponding display screen parameter of 240HZ, or the display device can convert a display screen parameter corresponding to the high-brush signal of 120HZ into a corresponding display screen parameter of 240 HZ. However, the display device cannot mutually convert the display screen parameter corresponding to the high brush signal of 120HZ, the corresponding display screen parameter of 240HZ, and the corresponding display screen parameter of 240 HZ.

This is because the high brush signal of 120HZ or the high brush signal corresponding to 144HZ is a hard high brush, that is, the display screen itself of the display device has the display screen parameter corresponding to the high brush signal of 120HZ or the display screen itself of the display device has the display screen parameter corresponding to the high brush signal of 120 HZ. While the high brush signal of 240HZ is a soft high brush, i.e., the display device may adjust the display screen parameters of the display device to the corresponding display screen parameters of 240HZ by some software technique (e.g., DLG, HSR techniques), such as adjusting the refresh rate of the display screen of the display device to 240HZ.

When the two-row grid line (DLG) technology is adopted, the vertical pixel rendering precision is reduced, only odd rows (or even rows) such as 1, 3, 5, 7 and 9 are rendered, and then the data of the technical rows are copied to the even rows of 2, 4, 6, 8 and 10 for displaying. At this time, the number of the refreshing time is reduced by half, so that the refreshing time is reduced by half compared with the original refreshing time, and the refreshing rate of the display screen can be improved. That is, the principle of the DLG technology is similar to that of interlacing, and the DLG technology adopts a mode of scanning two repeated lines at a time to display, so that not only can the bandwidth be saved, but also the rough feeling of pictures caused by interlacing can be avoided. However, it is needless to say that the interval line that is repeatedly scanned should be information of other colors, and the improvement of the refresh rate by the display device through the DLG technology is that a part of the picture content is substantially lost, so that the actual appearance of the displayed picture is greatly reduced.

The hardware super-resolution (hardware super resolution, HSR) technology is similar to the basic principle of DLG, and is also to compress vertical pixels, only render odd lines (or even lines), and the even lines fuse the information of two adjacent lines for display. Therefore, compared with the DLG technology, after the picture adopting the HSR technology is fused with even-numbered pixels, the color and the line transition of the whole picture are more natural, and the definition is correspondingly improved.

When the HSR technology is used for switching the display screen parameters, two steps are mainly needed, namely, a System On Chip (SOC) of the display device is switched to display screen parameters corresponding to 240HZ, half of pixel information is removed in an interlaced mode, and the whole screen is stretched through a rear-end logic board (timing controller, TCON).

The logic board is also called a screen driving board, a central control board and a TCON board. The TCON board is used for processing LVDS or TTL image data signals sent by the digital board, the clock signal stops processing the image data signals stored in the shift storage device, and the clock signal is converted into a control signal row-column signal RSDS which can be recognized by the screen to control the MOSFET in the screen to work so as to control the torsion degree of the liquid crystal molecules.

That is, for the HSR technology and the DLG technology, which are called "soft high brushing", the display screen of the present display device has only a display capability corresponding to 120HZ at the highest, but wants to display content corresponding to 240 HZ. However, the display screen of the display device has insufficient performance (such as insufficient liquid crystal performance and insufficient driving voltage), manufacturers want a method to directly scan two lines at a time, the contents of the two lines are the same, the scanned information is directly halved, and the pulling feeling of interlaced scanning is not easy to be seen, but the information quantity is directly halved, and half of definition is lost, so that the picture smoothness is changed.

When the display device is connected with the high-brush signal of 120HZ, the display device can also open the HSR function, so that frequency multiplication is carried out to 240HZ output, namely, the display device can switch the display screen parameter corresponding to the high-brush signal of 120HZ to the display screen parameter corresponding to the high-brush signal of 240HZ through the HSR function, so that the display device can display the content corresponding to the high-brush signal of 240 HZ. When the display device is connected with the high-brush signal of 144HZ, the display device cannot multiply frequency to 240HZ output, the display device must close the HSR function and set a gray switch, namely, the display device can switch the display screen parameter corresponding to the high-brush signal of 144HZ to the display screen parameter corresponding to the high-brush signal of 240HZ by closing the HSR function, so that the display device can display the content corresponding to the high-brush signal of 240 HZ.

That is, the display parameters corresponding to the high brush signal of 240HZ are controlled by the switch of the HSR function, and when the HSR function is turned on, the display device outputs 240HZ (i.e., the display parameters of the display device are adjusted to the display parameters corresponding to the high brush signal of 240 HZ). That is, if the high-brush signal input to the display device by the HDMI device is 240HZ, the display device will forcibly turn on the HSR function, so that the display screen parameter triggering the display device will be adjusted to the display screen parameter corresponding to the high-brush signal of 240 HZ.

For switching between the high-brush signal of 240HZ and the high-brush signal of 120HZ, namely when the display screen parameter corresponding to the high-brush signal of 240HZ is the display screen parameter, the HSR function is opened, the database is not written, and the display screen parameter can be switched to the display screen parameter corresponding to the high-brush signal of 240 HZ. When the HSR function in the database is turned off and the display screen parameter is the display screen parameter corresponding to the high-brush signal with the display screen parameter of 120HZ, the display screen parameter can be switched to the display screen parameter corresponding to the high-brush signal with the display screen parameter of 120HZ, and the control of the display screen parameter is controlled by the middleware in the display equipment. When the HSR function in the database is on, the display screen parameters corresponding to the high-brushing signal of 240HZ are kept unchanged, and the display screen parameters are not switched.

When the display device is connected with the 144HZ high-brush signal, the display screen parameter corresponding to the 144HZ high-brush signal is identified by the bottom layer of the display device to be automatically switched, so that when the 240HZ high-brush signal is connected with the 144HZ high-brush signal, the HDMI device is required to pull down the hot plug detection (hot olug detection, HPD) again, and the HDMI input high-brush signal is identified again. And for switching the high-brush signal of 144HZ to the high-brush signal of 240HZ, the middleware of the display device sends the display screen parameters corresponding to the high-brush signal of 240 HZ. It should be noted that, the display screen parameters corresponding to the high-brush signal at 144HZ and the display screen parameters corresponding to the high-brush signal at 240HZ are not directly switched, and the display screen parameters corresponding to the high-brush signal at 120HZ are switched in the middle.

The middleware of the display device is a type of software between the application system and the system software, uses basic services (functions) provided by the system software, and is connected with various parts of the application system or different applications on the network, so that the purposes of resource sharing and function sharing can be achieved. That is, the switching of the display screen parameters of the display device may be controlled by the middleware of the display device.

The display device does not support the variable refresh rate function when the display device is connected to the high brush signal of 240HZ, since the variable refresh rate function requires that the refresh rate of the display screen is variable, whereas the refresh rate of the display screen is fixed when the display device is connected to the high brush signal of 240HZ, i.e. the variable refresh rate function of the display device is mutually exclusive with the HSR function. vrr/fresync and HSR functions are mutually exclusive. The variable refresh rate function may be a variable refresh rate (variable refresh rate, vrr) or a display variable frequency technique (freesync).

In summary, in the prior art, the display screen parameters of the display device can be adjusted from the display screen parameters corresponding to the high-brush signal of 120HZ to the display screen parameters corresponding to the high-brush signal of 240HZ and from the display screen parameters corresponding to the high-brush signal of 144HZ to the display screen parameters corresponding to the high-brush signal of 240HZ, but in the prior art, the display screen parameters of the display device cannot be converted between the display screen parameters corresponding to the high-brush signal of 120HZ, the display screen parameters corresponding to the high-brush signal of 144HZ and the display screen parameters corresponding to the high-brush signal of 240HZ, so that the 120HZ, 144HZ and 240HZ high-brush signals cannot be concentrated on one display device in the prior art, and switching between three timing signals cannot be realized. That is, the display screen parameters (i.e., screen parameters) of the display device in the prior art are fixed and cannot be converted with each other, so that the display device in the prior art cannot concentrate the high-brushing signals of 120HZ, 144HZ and 240HZ onto one display device, and cannot switch back and forth between the three timing signals.

In view of the foregoing, an embodiment of the present application provides a display method, which should be applied to a display device, where the display device may receive a 120HZ high-brush signal, a 144HZ high-brush signal, or a 240HZ high-brush signal, and adjust a display screen parameter of the display device to a display screen parameter corresponding to the 120HZ high-brush signal, a display screen parameter corresponding to the 144HZ high-brush signal, or a display screen parameter corresponding to the 240HZ high-brush signal, so that the display screen may display content corresponding to the 120HZ high-brush signal, the 144HZ high-brush signal, or the 240HZ high-brush signal.

That is, the scheme provided by the application can enable the display screen parameters of the display device to be mutually converted, so that the display device can simultaneously support high-brushing signals with multiple frequencies (such as 120HZ, 144HZ and 240 HZ). That is, the display device can concentrate high-brush signals with various frequencies (such as 120HZ, 144HZ and 240 HZ) on one display device, and can realize switching back and forth among three timing signals.

The methods in the following embodiments may be implemented in a display device having the above-described hardware structure or software structure.

According to the scheme, the display device can receive the 120HZ high-brush signal, the 144HZ high-brush signal or the 240HZ high-brush signal, and the display screen parameters of the display device are adjusted to display screen parameters corresponding to the 120HZ high-brush signal, display screen parameters corresponding to the 144HZ high-brush signal or display screen parameters corresponding to the 240HZ high-brush signal, so that the display screen can display contents corresponding to the 120HZ high-brush signal, the 144HZ high-brush signal or the 240HZ high-brush signal. The display screen parameters of the display device are adjusted to display screen parameters corresponding to the high-brush signal of 120HZ, display screen parameters corresponding to the high-brush signal of 144HZ or display screen parameters corresponding to the high-brush signal of 240HZ respectively by combining with the accompanying drawings.

The following describes in detail the display method provided in the embodiment of the present application with reference to fig. 5. As shown in fig. 5, taking an example of adjusting a display screen parameter corresponding to a high-brush signal of 120HZ to a display screen parameter corresponding to a high-brush signal of 240HZ as an illustration, the display method provided in the embodiment of the present application may include the following S501-S509.

S501, turning off the regional dimming function.

The current high-brushing signal received by the display device is a high-brushing signal of 120HZ, and the display screen parameter of the display device is the display screen parameter corresponding to the high-brushing signal of 120 HZ. When the high-brush signal received by the display device is changed into a high-brush signal of 240HZ, the display device needs to adjust the display screen parameter corresponding to the high-brush signal of 120HZ to the display screen parameter corresponding to the high-brush signal of 240 HZ.

The display screen parameter may be simply referred to as a screen parameter in the embodiment of the present application. The display screen parameters may include a refresh rate of the display screen. For example, when the currently received high-brush signal of the display device is a high-brush signal of 120HZ, the refresh rate of the display device may be 120HZ, so that the content corresponding to the high-brush signal of 120HZ can be better displayed. The display screen parameters may also include basic content such as pixel pitch, resolution, scanning frequency, refresh rate, power consumption, electromagnetic radiation, etc. The large screen display adopts a single chip computer technology to control the digital mode, and can realize the control of parameters such as image shape, gray scale, brightness, color and the like in a button mode.

When the high-brush signal received by the display device is changed into a high-brush signal of 240HZ, the display device needs to adjust the display screen parameter corresponding to the high-brush signal of 120HZ to the display screen parameter corresponding to the high-brush signal of 240 HZ. When the display screen parameter corresponding to the high-brush signal of 120HZ is adjusted to the display screen parameter corresponding to the high-brush signal of 240HZ, the HSR function of the display device needs to be turned on, and when the HSR function is turned on, the output signal of the display device is changed from 4K2K120HZ to 4K1K240HZ, and the change of the regional dimming can be affected in the changing process, so that the display device can turn off the regional dimming function before the display device adjusts the display screen parameter corresponding to the high-brush signal of 120HZ to the display screen parameter corresponding to the high-brush signal of 240 HZ. For example, the display device may turn off the local dimming function through middleware of the display device.

Local dimming, meaning Local backlight adjustment, is that a backlight composed of hundreds of LEDs is used to replace a CCFL backlight, backlight LEDs can be adjusted according to brightness of an image, brightness of a highlighted portion in a display screen image can be maximized, and meanwhile, a darkened portion can be reduced in brightness and even turned off, so that optimal contrast is achieved. Thus, the reduction of the brightness of the dark area reduces the power consumption of the backlight.

S502, turning off the variable refresh rate function.

When the high-brush signal received by the display device is changed into a high-brush signal of 240HZ, the display device needs to adjust the display screen parameter corresponding to the high-brush signal of 120HZ to the display screen parameter corresponding to the high-brush signal of 240 HZ.

Since the HSR function of the display device needs to be turned on when the display screen parameter corresponding to the high brush signal of 120HZ is adjusted to the display screen parameter corresponding to the high brush signal of 240HZ, and the display device does not support the variable refresh rate function when the HSR function is turned on, that is, the display device does not support Vrr and freesync when the HSR function is turned on, the display device may turn off the variable refresh rate function (that is, vrr and freesync) region dimming function before the display device adjusts the display screen parameter corresponding to the high brush signal of 120HZ to the display screen parameter corresponding to the high brush signal of 240 HZ. For example, the display device may turn off the variable refresh rate function (i.e., vrr and freesync) local dimming function through the middleware of the display device.

S503, turning on a black shielding function.

Because the HSR function of the display device needs to be turned on when the display screen parameter corresponding to the high-brush signal of 120HZ is adjusted to the display screen parameter corresponding to the high-brush signal of 240HZ, and garbage garge exists in the process of turning on the HSR function, before the display device adjusts the display screen parameter corresponding to the high-brush signal of 120HZ to the display screen parameter corresponding to the high-brush signal of 240HZ, the display device can turn on the black-out function, so that the display device can ensure that the garge cannot be displayed in the process of adjusting the display screen parameter corresponding to the high-brush signal of 120HZ to the display screen parameter corresponding to the high-brush signal of 240 HZ. For example, the display device may turn off the on blackout function through middleware of the display device.

In some examples, the display device turns on the blackout function, which may be self-blackout when TCON turns on the HSR function. And when TCON does not support blackout, the display device may be blacked out by turning off the backlight.

S504, sending an instruction for opening the HSR function to the TCON.

After the display device turns on the blackout function, the middleware of the display device may send an instruction to the TCON to turn on the HSR function. The instruction for opening the HSR function may be used to instruct the TCON to open the HSR function of the display device.

After the TCON receives the instruction for opening the HSR function sent by the middleware of the display device, the TCON may open the HSR function of the display device.

S505, sending a VGH voltage rewriting instruction to the back-end PMU chip.

After the middleware of the display device sends an instruction of turning on the HSR function to the TCON, the TCON turns on the HSR function of the display device, the middleware of the display device may send an instruction of rewriting the VGH voltage to a back-end power management unit (power management unit, PMU) of the display device, so that the back-end PMU chip may optimize the VGH voltage. The VGH voltage command can be used for indicating to optimize VGH voltage, so that the problems of dark lines and the like of display screen parameters corresponding to high-brush signals with the display screen parameters adjusted to 240HZ by the display equipment can be avoided.

S506, sending a switching notification to the SOC, wherein the switching notification indicates to switch to the screen parameter corresponding to 240 HZ.

After the middleware of the display device sends an instruction to rewrite the VGH voltage to the back-end PMU chip, the back-end PMU chip optimizes the VGH voltage, the middleware of the display device may send a switching notification to the SOC of the display device. The switch notification may be used to instruct switching of the display screen parameters (i.e., screen parameters) to the screen parameters corresponding to 240 HZ.

After the SOC of the display device receives the switching notification sent by the middleware of the display device, the SOC may switch the display screen parameter to the screen parameter corresponding to the high-brush signal of 240 HZ.

S507, sending an adjustment notice to the application window, and adjusting the size of the window.

After the SOC of the display device switches the display screen parameter to the screen parameter corresponding to the high-brush signal of 240HZ, the middleware of the display device may send an adjustment notification to the display device application window (i.e., applywindow), and the adjustment notification may be used to indicate the size of the adjustment window.

S508, turning off the black shading function.

After the middleware of the display device may send an adjustment notification to the display device application window, the middleware of the display device may turn off the blackout function after the window is resized.

S509, setting a gear corresponding to the regional dimming function.

After the middleware of the display device closes the black shielding function, the middleware of the display device can set a gear corresponding to the local dimming function, namely resetting a localdiming gear of a user.

When the signal received by the display device is switched from the high-brush signal of 144HZ to the high-brush signal of 240HZ, the display device may adjust the display screen parameter corresponding to the high-brush signal of 144HZ to the display screen parameter corresponding to the high-brush signal of 240HZ, so that the display screen may display the content corresponding to the high-brush signal of 240 HZ. The display device adjusts the display screen parameter corresponding to the high-brush signal with the frequency of 144HZ to the display screen parameter corresponding to the high-brush signal with the frequency of 240HZ, and the display device adjusts the display screen parameter corresponding to the high-brush signal with the frequency of 120HZ to the display screen parameter corresponding to the high-brush signal with the frequency of 240 HZ. That is, when the signal received by the display device is switched from the high-brush signal of 144HZ to the high-brush signal of 240HZ, the display device adjusts the display screen parameter from the display screen parameter corresponding to the high-brush signal of 144HZ to the display screen parameter corresponding to the high-brush signal of 240HZ, which may refer to S501-S509 described above.

The following describes in detail the display method provided in the embodiment of the present application with reference to fig. 6. As shown in fig. 6, taking an example of adjusting a display screen parameter corresponding to a high-brush signal of 240HZ to a display screen parameter corresponding to a high-brush signal of 120HZ as an illustration, the display method provided in the embodiment of the present application may include the following S601-S611.

Because the HSR function of the display device needs to be turned off when the display screen parameter corresponding to the 240HZ high-brush signal is adjusted to the display screen parameter corresponding to the 120HZ high-brush signal, and the change of the regional dimming can be affected in the process from on to off of the HSR function, the display device can turn off the regional dimming function before the display device adjusts the display screen parameter corresponding to the 240HZ high-brush signal to the display screen parameter corresponding to the 120HZ high-brush signal.

For example, the display device may turn off the on blackout function through middleware of the display device.

S606, sending an instruction for closing the HSR function to the TCON.

After the display device turns on the blackout function, the middleware of the display device may send an instruction to turn off the HSR function to the TCON. The instruction to close the HSR function may be used to instruct the TCON to close the HSR function of the display device.

After the TCON receives the instruction of closing the HSR function sent by the middleware of the display device, the TCON may close the HSR function of the display device.

After the middleware of the display device sends an instruction for rewriting the VGH voltage to the back-end PMU chip, the back-end PMU chip optimizes the VGH voltage, the middleware of the display device can pull the HPD again to re-recognize the high-brush signal input by the HDMI, i.e. re-recognize the high-brush signal of 144HZ sent by the HDMI device.

After the middleware of the display device can newly pull down the HPD and newly recognize the high-brush signal input by the HDMI, the middleware of the display device can send a switching notification to the SOC of the display device. The switch notification may be used to instruct switching of the display screen parameters (i.e., the screen parameters) to the screen parameters corresponding to 144 HZ.

After the SOC of the display device receives the switching notification sent by the middleware of the display device, the SOC may switch the display screen parameter to the screen parameter corresponding to the high-brush signal of 144 HZ.

S706, sending an adjustment notice to the application window, and adjusting the size of the window.

S707, closing the black shading function.

S708, setting a gear corresponding to the regional dimming function.

According to the display method provided by the embodiment of the application, when the signal received by the display equipment is switched from the high-brush signal of 240HZ to the high-brush signal of 144HZ, the display equipment can adjust the display screen parameter corresponding to the high-brush signal of 240HZ to the display screen parameter corresponding to the high-brush signal of 144HZ, so that the display screen can display the content corresponding to the high-brush signal of 144 HZ.

For ease of understanding, in the display method provided in the embodiment of the present application, a process in which the display screen parameter is adjusted from the display screen parameter corresponding to the high brush signal of 120HZ to the display screen parameter corresponding to the high brush signal of 240HZ, the display screen parameter is adjusted from the display screen parameter corresponding to the high brush signal of 144HZ to the display screen parameter corresponding to the high brush signal of 240HZ, the display screen parameter corresponding to the high brush signal of 240HZ is adjusted to the display screen parameter corresponding to the high brush signal of 120HZ, and the display screen parameter corresponding to the high brush signal of 144HZ is described below with reference to fig. 8.

Because the display screen parameter is adjusted from the display screen parameter corresponding to the high-brush signal of 120HZ to the display screen parameter corresponding to the high-brush signal of 240HZ, and the display screen parameter is adjusted from the display screen parameter corresponding to the high-brush signal of 144HZ to the display screen parameter corresponding to the high-brush signal of 240HZ, the display equipment needs to turn on the HSR function. Therefore, as shown in fig. 8, the process of adjusting the display screen parameter from the display screen parameter corresponding to the high brush signal of 120HZ to the display screen parameter corresponding to the high brush signal of 240HZ and the process of adjusting the display screen parameter from the display screen parameter corresponding to the high brush signal of 144HZ to the display screen parameter corresponding to the high brush signal of 240HZ are the same, and both the steps include: closing the regional dimming function, closing the variable refresh rate function, opening the black shielding function, sending an instruction for opening the HSR function to the TCON, sending an instruction for rewriting VGH voltage to the back-end PMU chip, sending a switching notification to the SOC, switching the switching notification to a screen parameter corresponding to 240HZ, sending an adjustment notification to an application window, adjusting the size of the window, closing the black shielding function, and setting a gear corresponding to the regional dimming function.

When the display screen parameter is adjusted from the display screen parameter corresponding to the high-brush signal of 240HZ to the display screen parameter corresponding to the high-brush signal of 120HZ or the display screen parameter corresponding to the high-brush signal of 144HZ, as shown in fig. 8, the display device determines whether to be tangential 120HZ or 144HZ. At tangential 120HZ, the display device needs to read the status of the HSR function in the database. It is then determined whether the state of the HSR function is an on state. When the state of the HSR function is an on state, the display device may keep the HSR function in the on state, so as to adjust the display screen parameter from the display screen parameter corresponding to the high brush signal of 240HZ to the display screen parameter corresponding to the high brush signal of 120 HZ. When the state of the HSR function is in a closed state, the display device can close the regional dimming function, open the black shielding function, send an instruction for closing the HSR function to the TCON, send an instruction for rewriting VGH voltage to the back-end PMU chip, send a switching notification to the SOC, switch the switching notification to a screen parameter corresponding to 120HZ, send an adjustment notification to the application window, adjust the size of the window, close the black shielding function and set a gear corresponding to the regional dimming function.
