[0002] Currently, HDMI (high definition multimedia interface) has been widely used in display devices such as televisions. HDMI is a digital video / audio interface technology that can transmit audio and video signals simultaneously.

[0003] HDMI devices can input high refresh signals of different frequencies to display devices such as televisions, such as a 120 Hz (hertz, HZ) high refresh signal, a 144 Hz high refresh signal, or a 240 Hz high refresh signal.

[0004] The display screen parameters of the display device can be display screen parameters corresponding to high refresh signals of different frequencies, so as to ensure the clarity and smoothness of the picture displayed by the display device. For example, when the display screen parameters of the display device are display screen parameters corresponding to a high refresh signal of 120HZ, the display device can receive and display the 120HZ high refresh signal input by the HDMI device, when the display screen parameters of the display device are display screen parameters corresponding to 144HZ, the display device can receive and display the 144HZ high refresh signal input by the HDMI device, and when the display screen parameters of the display device are display screen parameters corresponding to 240HZ, the display device can receive and display the 240HZ high refresh signal input by the HDMI device.

In addition, the character " / " in this disclosure generally indicates that the associated objects before and after are in an "or" relationship.

[0051] Currently, HDMI (high definition multimedia interface) has been widely used in display devices such as televisions. HDMI is a digital video / audio interface technology that can transmit audio and video signals simultaneously.

[0052] In order to fully adapt to users' high-end demands for e-sports games, sports events and high-speed Blu-ray movies, thereby bringing a clear, smooth and comfortable perfect visual feast, HDMI devices can input timing signals of different frequencies to display devices such as TVs through the HDMI channel, that is, high refresh signals, such as 120 Hz (hertz, HZ) high refresh signals, or 144HZ high refresh signals, or 240HZ high refresh signals.

[0053] The display screen parameters (also referred to as screen parameters) of the display device can be display screen parameters corresponding to high refresh signals of different frequencies, so as to ensure the clarity and smoothness of the picture displayed by the display device. For example, when the display screen parameters of the display device are display screen parameters corresponding to a high refresh signal of 120HZ, the display device can receive and display a high refresh signal of 120HZ input by an HDMI device, when the display screen parameters of the display device are display screen parameters corresponding to 144HZ, the display device can receive and display a high refresh signal of 144HZ input by an HDMI device, and when the display screen parameters of the display device are display screen parameters corresponding to 240HZ, the display device can receive and display a high refresh signal of 240HZ input by an HDMI device.

[0054] However, the display parameters of current display devices cannot be converted to each other, which results in the display devices being unable to support high refresh signals of multiple frequencies (such as 120HZ, 144HZ and 240HZ) at the same time. In other words, current display devices have not yet concentrated high refresh signals of multiple frequencies (such as 120HZ, 144HZ and 240HZ) on one display device, and if high refresh signals of multiple frequencies (such as 120HZ, 144HZ and 240HZ) are concentrated on one display device, there will be a scenario where three timming signals are switched back and forth.

[0055] At present, some display devices can switch from a 120HZ high refresh signal to a 240HZ high refresh signal, or from a 144HZ high refresh signal to a 240HZ high refresh signal, that is, the display device can convert the display screen parameters corresponding to the 120HZ high refresh signal to the corresponding display screen parameters of 240HZ, or the display device can convert the display screen parameters corresponding to the 120HZ high refresh signal to the corresponding display screen parameters of 240HZ. However, the display device cannot convert the display screen parameters corresponding to the 120HZ high refresh signal, the display screen parameters corresponding to 240HZ, and the display screen parameters corresponding to 240HZ.

[0056] This is because the 120HZ high refresh signal or the high refresh signal corresponding to 144HZ is a hard high refresh, that is, the display screen of the display device itself has the display screen parameters corresponding to the 120HZ high refresh signal or the display screen of the display device itself has the display screen parameters corresponding to the 120HZ high refresh signal. The 240HZ high refresh signal is a soft high refresh, that is, the display device can use some software technology (such as DLG, HSR technology) to adjust the display screen parameters of the display device to the display screen parameters corresponding to 240HZ, such as adjusting the refresh rate of the display screen of the display device to 240HZ.

[0057] The dual line gate (DLG) technology reduces the vertical pixel rendering accuracy and only renders odd lines (or even lines) such as 1, 3, 5, 7, and 9, and then copies the data of the technical line to the even lines of 2, 4, 6, 8, and 10 for display. At this time, the number of vertical refreshes required is reduced by half, so the refresh time is reduced by half compared to the original, so the refresh rate of the display can be improved. That is, the principle of DLG technology is similar to interlaced scanning. It uses a method of scanning two repeated lines at a time for display, which can not only save bandwidth, but also avoid the roughness of the picture caused by interlaced scanning. But there is no doubt that the repeatedly scanned interlaced lines should be other colors and other information. The improvement of the refresh rate through the display device through the DLG technology is essentially the loss of this part of the picture content, which greatly reduces the actual look and feel of the displayed picture.

[0058] Hardware super resolution (HSR) technology is similar to DLG in that it compresses vertical pixels and only renders odd (or even) rows, while even rows are displayed by fusing the information of two adjacent rows. Therefore, compared with DLG technology, the HSR technology will make the color and line transition of the entire picture more natural and the clarity will be improved accordingly after fusing the even rows of pixels.

[0059] There are two main steps to switch the display parameters using HSR technology. The first is to switch the display parameters to the display parameters corresponding to 240HZ by the system-on chip (SOC) of the display device, and remove half of the pixel information every other line. The second is to stretch the display through the back-end logic board (timing controller, TCON) to fill the full screen.

[0060] The logic board is also called the screen driver board, central control board, or TCON board. The TCON board is used to process the LVDS or TTL image data signal and clock signal sent by the digital board, and the shift register stores the image data signal and clock signal, and converts them into control signals that can be recognized by the screen, such as row and column signals RSDS, which control the operation of the MOSFET tube in the screen and control the distortion of the liquid crystal molecules.

[0061] That is to say, for the so-called "soft high refresh" of HSR and DLG technologies, the current display screen of the display device has a maximum display capacity of only 120HZ, but it wants to display the content corresponding to 240HZ. However, the performance of the display screen of the display device is insufficient (such as insufficient liquid crystal performance and driving voltage), so the manufacturer has come up with a solution to directly scan two lines at a time. The content of the two lines is the same, which directly leads to the reduction of the scanned information by half. It is not easy to see the pulling feeling of interlaced scanning, but the amount of information is directly halved, which will lose half of the clarity, in exchange for the smoothness of the picture.

[0062] When the display device is connected to a 120HZ high refresh signal, the display device can also turn on the HSR function to multiply the frequency to 240HZ output, that is, the display device can switch the display screen parameters corresponding to the 120HZ high refresh signal to the display screen parameters corresponding to the 240HZ high refresh signal through the HSR function, so that the display device can display the content corresponding to the 240HZ high refresh signal. When the display device is connected to a 144HZ high refresh signal, the display device cannot multiply the frequency to 240HZ output. The display device must turn off the HSR function and gray out the switch, that is, the display device can switch the display screen parameters corresponding to the 144HZ high refresh signal to the display screen parameters corresponding to the 240HZ high refresh signal by turning off the HSR function, so that the display device can display the content corresponding to the 240HZ high refresh signal.

[0063] In other words, the display screen parameters corresponding to the 240HZ high refresh signal are controlled by the switch of the HSR function. When the HSR function is turned on, the display device will output 240HZ (that is, the display screen parameters of the display device will be adjusted to the display screen parameters corresponding to the 240HZ high refresh signal). That is, if the high refresh signal input to the display device by the HDMI device is 240HZ, the display device will force the HSR function to be turned on, thereby triggering the display screen parameters of the display device to be adjusted to the display screen parameters corresponding to the 240HZ high refresh signal.

[0064] For the switching between the high refresh signal of 240HZ and the high refresh signal of 120HZ, that is, when the display parameters are the display parameters corresponding to the high refresh signal of 240HZ, the HSR function is turned on, and the database is not written, and the display parameters can be switched to the display parameters corresponding to the high refresh signal of 240HZ. When the display parameters are the display parameters corresponding to the high refresh signal of 120HZ, when the HSR function in the database is turned off, the display parameters can be switched to the display parameters corresponding to the high refresh signal of 120HZ, and the control of the display parameters is controlled by the middleware in the display device. When the HSR function is turned on in the database, the display parameters corresponding to the high refresh signal of 240HZ remain unchanged, and the display parameters are not switched.

[0065] When the display device is connected to a 144HZ high refresh signal, the display screen parameters corresponding to the 144HZ high refresh signal are automatically switched by the bottom layer of the display device after recognizing the signal. Therefore, when the 240HZ high refresh signal is switched to the 144HZ high refresh signal, the HDMI device needs to re-pull the hot plug detection (HPD) to re-identify the HDMI input high refresh signal. For the switch from the 144HZ high refresh signal to the 240HZ high refresh signal, the display screen parameters corresponding to the 240HZ high refresh signal are sent by the middleware of the display device. It should be noted that the display screen parameters corresponding to the 144HZ high refresh signal and the display screen parameters corresponding to the 240HZ high refresh signal are not switched directly to each other. In the middle, they must first switch to the display screen parameters corresponding to the 120HZ high refresh signal.

[0066] The middleware of display devices is a type of software between the application system and the system software. It uses the basic services (functions) provided by the system software to connect various parts of the application system or different applications on the network, and can achieve the purpose of resource sharing and function sharing. In other words, the switching of the display screen parameters of the display device can be controlled by the middleware of the display device.

[0067] When the display device is connected to a 240HZ high refresh signal, the display device does not support the variable refresh rate function. Since the variable refresh rate function requires the refresh rate of the display to be variable, and when the display device is connected to a 240HZ high refresh signal, the refresh rate of the display is fixed, that is, the variable refresh rate function of the display device is mutually exclusive with the HSR function. vrr / freesync and HSR functions are mutually exclusive. The variable refresh rate function can be a variable refresh rate (variable refresh rate, Vrr) or a display frequency conversion technology (freesync).

[0068] In summary, although the display screen parameters of the display device can be adjusted from the display screen parameters corresponding to the high refresh signal of 120HZ to the display screen parameters corresponding to the high refresh signal of 240HZ, and from the display screen parameters corresponding to the high refresh signal of 144HZ to the display screen parameters corresponding to the high refresh signal of 240HZ in the prior art, the display screen parameters of the display device cannot be mutually converted between the display screen parameters corresponding to the high refresh signal of 120HZ, the display screen parameters corresponding to the high refresh signal of 144HZ, and the display screen parameters corresponding to the high refresh signal of 240HZ in the prior art. Therefore, the high refresh signals of 120HZ, 144HZ and 240HZ cannot be concentrated on one display device in the prior art, and the switching back and forth between the three timming signals cannot be realized. In other words, the display screen parameters (i.e., screen parameters) of the display device in the prior art are fixed and cannot be mutually converted. Therefore, the display device in the prior art cannot concentrate the high refresh signals of 120HZ, 144HZ and 240HZ on one display device, and the switching back and forth between the three timming signals cannot be realized.

[0069] In response to the above problems, an embodiment of the present application provides a display method, which should be used on a display device, which can receive a high refresh signal of 120HZ, a high refresh signal of 144HZ, or a high refresh signal of 240HZ, and adjust the display screen parameters of the display device to the display screen parameters corresponding to the high refresh signal of 120HZ, the display screen parameters corresponding to the high refresh signal of 144HZ, or the display screen parameters corresponding to the high refresh signal of 240HZ, so that the display screen can display the content corresponding to the high refresh signal of 120HZ, the high refresh signal of 144HZ, or the high refresh signal of 240HZ.

[0070] That is to say, the solution provided by the present application can convert the display screen parameters of the display device to each other, so that the display device can simultaneously support high refresh signals of multiple frequencies (such as 120HZ, 144HZ and 240HZ). That is, the display device can concentrate high refresh signals of multiple frequencies (such as 120HZ, 144HZ and 240HZ) on one display device, and can realize switching back and forth between the three timing signals.

The user may control the display device 200 by inputting user commands through buttons on the remote controller, voice input, control panel input, etc.

[0075] In some embodiments, a smart device 300 (such as a mobile terminal, a tablet computer, a computer, a laptop computer, etc.) may also be used to control the display device 200. For example, the display device 200 is controlled using an application running on the smart device.

[0077] In some embodiments, the display device 200 can also be controlled in a manner other than the control device 100 and the smart device 300. For example, the user's voice command control can be directly received through a module for obtaining voice commands configured inside the display device 200, or the user's voice command control can be received through a voice control device set outside the display device 200.

[0078] In some embodiments, the display device 200 also communicates data with the server 400. The display device 200 may be allowed to communicate via a local area network (LAN), a wireless local area network (WLAN), and other networks. The server 400 may provide various content and interactions to the display device 200. The server 400 may be one cluster or multiple clusters, and may include one or more types of servers.

[0079] Figure 2 Schematically shows a block diagram of a configuration of the control device 100 according to an exemplary embodiment. Figure 2 As shown, the control device 100 includes a controller 110, a communication interface 130, a user input / output interface 140, a memory, and a power supply. The control device 100 can receive input operation instructions from the user, and convert the operation instructions into instructions that the display device 200 can recognize and respond to, playing the role of an interactive intermediary between the user and the display device 200.

[0080] For example, taking the display device as a television, Figure 3 A schematic structural diagram of a display device provided in an embodiment of the present application is shown.

[0081] like Figure 3 The display device 200 includes at least one of a tuner and demodulator 210, a communicator 220, a detector 230, an external device interface 240, a controller 250, a display 260, an audio output interface 270, a memory, a power supply, and a user interface.

[0082] In some embodiments, the controller includes a processor, a video processor, an audio processor, a graphics processor, a RAM, a ROM, and a first interface to an nth interface for input / output.

[0083] The display 260 includes a display screen component for presenting images, and a driving component for driving image display, a component for receiving image signals output from a controller, and a component for displaying video content, image content, and a menu control interface, as well as a user control user interface (Use Interface, UI).

[0084] The display 260 may be a liquid crystal display, an OLED display, or a projection display, and may also be a projection device and a projection screen.

[0085] The communicator 220 is a component for communicating with an external device or server according to various communication protocol types. For example, the communicator may include at least one of a Wifi module, a Bluetooth module, a wired Ethernet module, and other network communication protocol chips or near field communication protocol chips, and an infrared receiver. The display device 200 can establish transmission and reception of control signals and data signals with the external control device 100 or the server 400 through the communicator 220.

[0086] The user interface can be used to receive control signals from the control device 100 (such as an infrared remote controller, etc.).

[0087] The detector 230 is used to collect signals from the external environment or the external interaction. For example, the detector 230 includes a light receiver, a sensor for collecting the intensity of ambient light; or, the detector 230 includes an image collector, such as a camera, which can be used to collect external environment scenes, user attributes or user interaction gestures; or, the detector 230 includes a sound collector, such as a microphone, etc., for receiving external sounds.

[0088] The external device interface 240 may include, but is not limited to, any one or more of the following: a high-definition multimedia interface (HDMI), an analog or digital high-definition component input interface (component), a composite video input interface (CVBS), a USB input interface (USB), an RGB port, etc. It may also be a composite input / output interface formed by the above multiple interfaces.

[0089] The tuner-demodulator 210 receives broadcast television signals via wired or wireless reception, and demodulates audio and video signals, such as EPG data signals, from a plurality of wireless or wired broadcast television signals.

[0090] In some embodiments, the controller 250 and the tuner-demodulator 210 may be located in different separate devices, that is, the tuner-demodulator 210 may also be located in an external device of the main device where the controller 250 is located, such as an external set-top box.

[0091] The controller 250 controls the operation of the display device and responds to user operations through various software control programs stored in the memory. The controller 250 controls the overall operation of the display device 200. For example, in response to receiving a user command for selecting a UI object to be displayed on the display 260, the controller 250 can perform operations related to the object selected by the user command.

[0092] In some embodiments, the controller includes a central processing unit (CPU), a video processor, an audio processor, a graphics processing unit (GPU), RAM Random Access Memory (RAM), ROM (Read-Only Memory, ROM), a first interface to an nth interface for input / output, a communication bus (Bus), etc.

[0093] The user may input a user command through a graphical user interface (GUI) displayed on the display 260, and the user input interface receives the user input command through the graphical user interface (GUI). Alternatively, the user may input a user command through a specific sound or gesture, and the user input interface recognizes the sound or gesture through a sensor to receive the user input command.

[0094] "User interface" is the medium interface for interaction and information exchange between applications or operating systems and users. It realizes the conversion between the internal form of information and the form acceptable to users. The commonly used form of user interface is the Graphical User Interface (GUI), which refers to the user interface related to computer operation displayed in a graphical way. It can be an icon, window, control or other interface element displayed on the display screen of a display device, where the control can include icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets and other visual interface elements.

[0095] It is understandable that, generally speaking, the realization of the display device functions requires not only the support of the above-mentioned hardware but also the cooperation of software.

[0096] Figure 4 It is a software structure block diagram of the display device provided in the embodiment of the present application.

[0097] In some embodiments, Figure 4 As shown, the system of the display device is divided into four layers, from top to bottom, namely the application layer (Applications) layer (referred to as the "application layer"), the application framework layer (Application Framework) layer (referred to as the "framework layer"), the Android runtime (Android runtime) and system library layer (referred to as the "system runtime library layer"), and the kernel layer.

[0098] In some embodiments, at least one application is running in the application layer, and these applications can be window programs, system settings programs, clock programs, etc. provided by the operating system, or applications developed by third-party developers. In specific implementations, the application packages in the application layer are not limited to the above examples.

[0099] The framework layer provides application programming interfaces (APIs) and programming frameworks for applications. The application framework layer includes some predefined functions. The application framework layer is equivalent to a processing center that determines the actions that applications in the application layer take. Through the API interface, applications can access resources in the system and obtain system services during execution. In some examples, the dialog system included in the display device can be located in the framework layer of the system of the display device.

[0100] like Figure 4As shown, in the embodiment of the present application, the application framework layer includes managers, content providers, etc., wherein the manager includes at least one of the following modules: an activity manager (ActivityManager) is used to interact with all activities running in the system; a location manager (Location Manager) is used to provide system services or applications with access to system location services; a package manager (Package Manager) is used to retrieve various information related to the application package currently installed on the device; a notification manager (NotificationManager) is used to control the display and clearing of notification messages; a window manager (Window Manager) is used to manage icons, windows, toolbars, wallpapers, and desktop components on the user interface.

[0101] In some embodiments, the activity manager is used to manage the life cycle of each application and the common navigation back function, such as controlling the exit, opening, and back of the application. The window manager is used to manage all window programs, such as obtaining the display screen size, determining whether there is a status bar, locking the screen, capturing the screen, and controlling the display window changes (for example, reducing the display window, shaking the display, distorting the display, etc.).

[0102] In some embodiments, the system runtime layer provides support for the upper layer, namely the framework layer. When the framework layer is used, the Android operating system will run the C / C++ library contained in the system runtime layer to implement the functions to be implemented by the framework layer.

[0103] In some embodiments, the kernel layer is a layer between hardware and software. Figure 4 As shown, the kernel layer includes at least one of the following drivers: audio driver, display driver, Bluetooth driver, camera driver, WIFI driver, USB driver, HDMI driver, sensor driver (such as fingerprint sensor, temperature sensor, pressure sensor, etc.), and power driver, etc.

[0104] The methods in the following embodiments can all be implemented in a display device having the above hardware structure or software structure.

[0105] In the solution of the present application, the display device can receive a high refresh signal of 120HZ, a high refresh signal of 144HZ, or a high refresh signal of 240HZ, and adjust the display screen parameters of the display device to the display screen parameters corresponding to the high refresh signal of 120HZ, the display screen parameters corresponding to the high refresh signal of 144HZ, or the display screen parameters corresponding to the high refresh signal of 240HZ, so that the display screen can display the content corresponding to the high refresh signal of 120HZ, the high refresh signal of 144HZ, or the high refresh signal of 240HZ. The following is a description of adjusting the display screen parameters of the display device to the display screen parameters corresponding to the high refresh signal of 120HZ, the display screen parameters corresponding to the high refresh signal of 144HZ, or the display screen parameters corresponding to the high refresh signal of 240HZ, respectively, in conjunction with the accompanying drawings.

[0106] The following is combined with Figure 5 The display method provided in the embodiment of the present application is described in detail. Figure 5 As shown, taking the adjustment of display screen parameters from display screen parameters corresponding to a high refresh signal of 120HZ to display screen parameters corresponding to a high refresh signal of 240HZ as an example for schematic illustration, the display method provided in the embodiment of the present application may include the following S501-S509.

[0107] S501, turn off the regional dimming function.

[0108] The high refresh signal currently received by the display device is a 120HZ high refresh signal, and the display screen parameters of the display device are the display screen parameters corresponding to the 120HZ high refresh signal. When the high refresh signal received by the display device changes to a 240HZ high refresh signal, the display device needs to adjust the display screen parameters corresponding to the 120HZ high refresh signal to the display screen parameters corresponding to the 240HZ high refresh signal.

[0109] Display screen parameters may be referred to as screen parameters in the embodiments of the present application. Display screen parameters may include the refresh rate of the display screen. For example, when the high refresh signal currently received by the display device is a 120HZ high refresh signal, the refresh rate of the display device may be 120HZ, so that the content corresponding to the 120HZ high refresh signal can be better displayed. Display screen parameters may also include basic contents such as pixel pitch, resolution, scanning frequency, refresh speed, power consumption, and electromagnetic radiation. Large-screen displays all use single-chip computer technology for digital mode control, which can realize the control of image shape, grayscale, brightness, color and other parameters in the form of buttons.

[0110] When the high refresh signal received by the display device changes to a high refresh signal of 240HZ, the display device needs to adjust the display parameters corresponding to the 120HZ high refresh signal to the display parameters corresponding to the 240HZ high refresh signal. When adjusting the display parameters corresponding to the 120HZ high refresh signal to the display parameters corresponding to the 240HZ high refresh signal, 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 changes from 4K2K120HZ to 4K1K240HZ, which will affect the change of regional dimming during the change. Therefore, before the display device adjusts the display parameters corresponding to the 120HZ high refresh signal to the display parameters corresponding to the 240HZ high refresh signal, the display device can turn off the regional dimming function. For example, the display device can turn off the regional dimming function through the middleware of the display device.

[0111] Local dimming means local backlight adjustment. It uses hundreds of LEDs to replace CCFL backlights. The backlight LEDs can be adjusted according to the brightness of the image. The brightness of the highlighted part of the display image can reach the maximum, while the dark part can be reduced or even turned off to achieve the best contrast. In this way, the reduction in the brightness of the dark area reduces the power consumption of the backlight.

[0112] S502, turn off the variable refresh rate function.

[0113] When the high refresh signal received by the display device becomes a high refresh signal of 240HZ, the display device needs to adjust the display screen parameters corresponding to the high refresh signal of 120HZ to the display screen parameters corresponding to the high refresh signal of 240HZ.

[0114] When adjusting the display parameters corresponding to the 120HZ high refresh signal to the display parameters corresponding to the 240HZ high refresh signal, the HSR function of the display device needs to be turned on, and when the HSR function is turned on, the display device does not support the variable refresh rate function, that is, when the HSR function is turned on, the display device does not support Vrr and freesync. Therefore, before the display device adjusts the display parameters corresponding to the 120HZ high refresh signal to the display parameters corresponding to the 240HZ high refresh signal, the display device can turn off the variable refresh rate function (that is, Vrr and freesync) regional dimming function. For example, the display device can turn off the variable refresh rate function (that is, Vrr and freesync) regional dimming function through the middleware of the display device.

[0115] S503, turning on the blackout function.

[0116] When adjusting the display parameters corresponding to the 120HZ high refresh signal to the display parameters corresponding to the 240HZ high refresh signal, the HSR function of the display device needs to be turned on, and there will be garbage in the process of turning on the HSR function. Therefore, before the display device adjusts the display parameters corresponding to the 120HZ high refresh signal to the display parameters corresponding to the 240HZ high refresh signal, the display device can turn on the black mask function, thereby ensuring that garbage will not be displayed in the process of adjusting the display parameters corresponding to the 120HZ high refresh signal to the display parameters corresponding to the 240HZ high refresh signal. For example, the display device can turn on and off the black mask function through the middleware of the display device.

[0117] In some examples, the display device turns on the blackout function, which can be blackout by itself when the TCON turns on the HSR function. When the TCON does not support blackout, the display device can turn off the backlight to blackout.

[0118] S504: Send an HSR function enable instruction to TCON.

[0119] After the display device turns on the blackout function, the middleware of the display device can send an HSR function turn-on instruction to the TCON. The HSR function turn-on instruction can be used to instruct the TCON to turn on the HSR function of the display device.

[0120] After TCON receives the HSR function enable instruction sent by the middleware of the display device, TCON may enable the HSR function of the display device.

[0121] S505 , sending a VGH voltage rewrite instruction to the back-end PMU chip.

[0122] After the display device's middleware sends an instruction to turn on the HSR function to TCON, and TCON turns on the HSR function of the display device, the display device's middleware can send an instruction to rewrite the VGH voltage to the display device's back-end power management unit (PMU), so that the back-end PMU chip can optimize the VGH voltage. The VGH voltage instruction can be used to indicate the optimization of the VGH voltage, thereby avoiding problems such as dark lines when the display device adjusts the display screen parameters to the display screen parameters corresponding to the high refresh signal of 240HZ.

[0123] S506. Send a switching notification to the SOC, where the switching notification indicates switching to the screen parameters corresponding to 240HZ.

[0124] After the middleware of the display device sends a VGH voltage rewrite instruction to the back-end PMU chip and the back-end PMU chip optimizes the VGH voltage, the middleware of the display device can send a switching notification to the SOC of the display device. The switching notification can be used to instruct the display screen parameters (i.e., screen parameters) to be switched to the screen parameters corresponding to 240HZ.

[0125] After the SOC of the display device receives the switching notification sent by the middleware of the display device, the SOC can switch the display screen parameters to the screen parameters corresponding to the high refresh signal of 240HZ.

[0126] S507: Send an adjustment notification to the application window to adjust the size of the window.

[0127] After the SOC of the display device switches the display screen parameters to the screen parameters corresponding to the high refresh signal of 240HZ, the middleware of the display device can send an adjustment notification to the application window of the display device (ie, Applywindow), and the adjustment notification can be used to indicate the size of the adjustment window.

[0128] S508: Turn off the blackout function.

[0129] The middleware of the display device may send an adjustment notification to the application window of the display device. After the size of the window is adjusted, the middleware of the display device may turn off the blackout function.

[0130] S509: Set the gear corresponding to the regional dimming function.

[0131] After the middleware of the display device turns off the blackout function, the middleware of the display device can set the gear corresponding to the regional dimming function, that is, reset the user's local dimming gear.

[0132] Through the display method provided in the embodiment of the present application, when the signal received by the display device switches from a high refresh signal of 120HZ to a high refresh signal of 240HZ, the display device can adjust the display screen parameters from the display screen parameters corresponding to the high refresh signal of 120HZ to the display screen parameters corresponding to the high refresh signal of 240HZ, so that the display screen can display the content corresponding to the high refresh signal of 240HZ.

[0133] It should be noted that when the signal received by the display device switches from a high refresh signal of 144HZ to a high refresh signal of 240HZ, the display device can adjust the display screen parameters from the display screen parameters corresponding to the high refresh signal of 144HZ to the display screen parameters corresponding to the high refresh signal of 240HZ, so that the display screen can display the content corresponding to the high refresh signal of 240HZ. The process of the display device adjusting the display screen parameters from the display screen parameters corresponding to the high refresh signal of 144HZ to the display screen parameters corresponding to the high refresh signal of 240HZ is the same as the process of the above-mentioned display device adjusting the display screen parameters from the display screen parameters corresponding to the high refresh signal of 120HZ to the display screen parameters corresponding to the high refresh signal of 240HZ. That is, when the signal received by the display device switches from a high refresh signal of 144HZ to a high refresh signal of 240HZ, the display device adjusts the display screen parameters from the display screen parameters corresponding to the high refresh signal of 144HZ to the display screen parameters corresponding to the high refresh signal of 240HZ, and reference can be made to the above-mentioned S501-S509.

[0134] The following is combined with Figure 6 The display method provided in the embodiment of the present application is described in detail. Figure 6 As shown, taking the adjustment of display screen parameters from display screen parameters corresponding to a high refresh signal of 240HZ to display screen parameters corresponding to a high refresh signal of 120HZ as an example for schematic illustration, the display method provided in the embodiment of the present application may include the following S601-S611.

[0135] S601. Read the status of the HSR function in the database.

[0136] The high refresh signal currently received by the display device is a 240HZ high refresh signal, and the display screen parameters of the display device are the display screen parameters corresponding to the 240HZ high refresh signal. When the high refresh signal received by the display device changes to a 120HZ high refresh signal, the display device needs to adjust the display screen parameters corresponding to the 240HZ high refresh signal to the display screen parameters corresponding to the 120HZ high refresh signal.

[0137] When the high refresh signal received by the display device becomes a high refresh signal of 120HZ, the display device needs to adjust the display parameters corresponding to the 240HZ high refresh signal to the display parameters corresponding to the 120HZ high refresh signal. The middleware of the display device can first read the status of the HSR function in the database to determine whether the HSR function is on or off.

[0138] S602: Determine whether the HSR function is in an on state.

[0139] When it is determined that the state of the HSR function is on, the following S603 may be continued to be executed. When it is determined that the state of the HSR function is off, the following S604 may be continued to be executed.

[0140] S603: Keep the HSR function turned on.

[0141] When it is determined that the state of the HSR function is turned off, the HSR function may be kept turned on.

[0142] S604: Turn off the regional dimming function.

[0143] When the high refresh signal received by the display device becomes a high refresh signal of 120HZ, the display device needs to adjust the display screen parameters corresponding to the 240HZ high refresh signal to the display screen parameters corresponding to the 120HZ high refresh signal. When adjusting the display screen parameters corresponding to the 240HZ high refresh signal to the display screen parameters corresponding to the 120HZ high refresh signal, the HSR function of the display device needs to be turned off, and the process of turning the HSR function on and off will affect the change of regional dimming. Therefore, before the display device adjusts the display screen parameters corresponding to the 240HZ high refresh signal to the display screen parameters corresponding to the 120HZ high refresh signal, the display device can turn off the regional dimming function. For example, the display device can turn off the regional dimming function through the middleware of the display device.

[0144] S605, turn on the blackout function.

[0145] Before the display device adjusts the display parameters corresponding to the 240HZ high refresh signal to the display parameters corresponding to the 120HZ high refresh signal, the display device can enable the black mask function, thereby ensuring that no garbage is displayed during the process of adjusting the display parameters corresponding to the 240HZ high refresh signal to the display parameters corresponding to the 120HZ high refresh signal. For example, the display device can turn off the black mask function through the middleware of the display device.

[0146] S606: Send a HSR function disable instruction to TCON.

[0147] After the display device turns on the blackout function, the middleware of the display device can send a HSR function turn-off instruction to the TCON. The HSR function turn-off instruction can be used to instruct the TCON to turn off the HSR function of the display device.

[0148] After TCON receives the HSR function shut down instruction sent by the middleware of the display device, TCON may shut down the HSR function of the display device.

[0149] S607 , sending a VGH voltage rewrite instruction to the back-end PMU chip.

[0150] After the middleware of the display device sends a command to turn off the HSR function to TCON, and TCON turns off the HSR function of the display device, the middleware of the display device can send a command to rewrite the VGH voltage to the back-end power management unit (PMU) of the display device, so that the back-end PMU chip can optimize the VGH voltage. The VGH voltage command can be used to indicate the optimization of the VGH voltage.

[0151] S608. Send a switching notification to the SOC, where the switching notification indicates switching to the screen parameters corresponding to 120HZ.

[0152] After the display device's middleware sends a VGH voltage rewrite instruction to the back-end PMU chip and the back-end PMU chip optimizes the VGH voltage, the display device's middleware can send a switching notification to the display device's SOC. The switching notification can be used to instruct the display screen parameters (i.e., screen parameters) to be switched to the screen parameters corresponding to 120HZ.

[0153] After the SOC of the display device receives the switching notification sent by the middleware of the display device, the SOC can switch the display screen parameters to the screen parameters corresponding to the high refresh signal of 120HZ.

[0154] S609: Send an adjustment notification to the application window to adjust the size of the window.

[0155] After the SOC of the display device switches the display screen parameters to the screen parameters corresponding to the high refresh signal of 120HZ, the middleware of the display device can send an adjustment notification to the application window of the display device (ie, Applywindow), and the adjustment notification can be used to indicate the size of the adjustment window.

[0156] S610, turn off the blackout function.

[0157] The middleware of the display device may send an adjustment notification to the application window of the display device. After the size of the window is adjusted, the middleware of the display device may turn off the blackout function.

[0158] S611. Set the gear corresponding to the regional dimming function.

[0159] After the middleware of the display device turns off the blackout function, the middleware of the display device can set the gear corresponding to the regional dimming function, that is, reset the user's local dimming gear.

[0160] Through the display method provided in the embodiment of the present application, when the signal received by the display device switches from a high refresh signal of 240HZ to a high refresh signal of 120HZ, the display device can adjust the display screen parameters from the display screen parameters corresponding to the high refresh signal of 240HZ to the display screen parameters corresponding to the high refresh signal of 120HZ, so that the display screen can display the content corresponding to the high refresh signal of 120HZ.

[0161] The following is combined with Figure 7 The display method provided in the embodiment of the present application is described in detail. Figure 7 As shown, taking the adjustment of display screen parameters from display screen parameters corresponding to a high refresh signal of 240HZ to display screen parameters corresponding to a high refresh signal of 144HZ as an example for schematic illustration, the display method provided in the embodiment of the present application may include the following S701-S708.

[0162] S701, turn off the regional dimming function.

Before the display device adjusts the display parameters corresponding to the 240HZ high refresh signal to the display parameters corresponding to the 144HZ high refresh signal, the display device can turn off the regional dimming function. For example, the display device can turn off the regional dimming function through the middleware of the display device.

[0164] S702, turn on the blackout function.

[0165] Before the display device adjusts the display parameters corresponding to the 240HZ high refresh signal to the display parameters corresponding to the 144HZ high refresh signal, the display device can enable the black mask function, thereby ensuring that no garbage is displayed during the process of adjusting the display parameters corresponding to the 240HZ high refresh signal to the display parameters corresponding to the 144HZ high refresh signal. For example, the display device can turn off the black mask function through the middleware of the display device.

[0166] S703: Send a command to TCON to disable the HSR function.

[0167] After the display device turns on the blackout function, the middleware of the display device can send a HSR function turn-off instruction to the TCON. The HSR function turn-off instruction can be used to instruct the TCON to turn off the HSR function of the display device.

[0168] After TCON receives the HSR function shut down instruction sent by the middleware of the display device, TCON may shut down the HSR function of the display device.

[0169] S704 , sending a VGH voltage rewrite instruction to the back-end PMU chip.

[0170] After the middleware of the display device sends a command to turn off the HSR function to TCON, and TCON turns off the HSR function of the display device, the middleware of the display device can send a command to rewrite the VGH voltage to the back-end power management unit (PMU) of the display device, so that the back-end PMU chip can optimize the VGH voltage. The VGH voltage command can be used to indicate the optimization of the VGH voltage.

[0171] S705. Pull the HPD again and send a switching notification to the SOC. The switching notification indicates switching to the screen parameters corresponding to 144HZ.

[0172] After the middleware of the display device sends a VGH voltage rewrite instruction to the back-end PMU chip and the back-end PMU chip optimizes the VGH voltage, the middleware of the display device can pull the HPD again and re-identify the high refresh signal of the HDMI input, that is, re-identify the 144HZ high refresh signal sent by the HDMI device.

[0173] After the middleware of the display device can re-pull the HPD and re-identify the high refresh signal of the HDMI input, the middleware of the display device can send a switching notification to the SOC of the display device. The switching notification can be used to indicate that the display screen parameters (i.e., screen parameters) should be switched to the screen parameters corresponding to 144HZ.

[0180] After the middleware of the display device turns off the blackout function, the middleware of the display device can set the gear corresponding to the regional dimming function, that is, reset the user's local dimming gear.

[0181] Through the display method provided in the embodiment of the present application, when the signal received by the display device switches from a high refresh signal of 240HZ to a high refresh signal of 144HZ, the display device can adjust the display screen parameters from the display screen parameters corresponding to the high refresh signal of 240HZ to the display screen parameters corresponding to the high refresh signal of 144HZ, so that the display screen can display the content corresponding to the high refresh signal of 144HZ.

[0182] For ease of understanding, the following Figure 8 The process of adjusting the display parameters from the display parameters corresponding to the high refresh signal of 120HZ to the display parameters corresponding to the high refresh signal of 240HZ, adjusting the display parameters from the display parameters corresponding to the high refresh signal of 144HZ to the display parameters corresponding to the high refresh signal of 240HZ, adjusting the display parameters from the display parameters corresponding to the high refresh signal of 240HZ to the display parameters corresponding to the high refresh signal of 120HZ, and adjusting the display parameters from the display parameters corresponding to the high refresh signal of 240HZ to the display parameters corresponding to the high refresh signal of 144HZ in the display method provided in the embodiments of the present application is described.

[0183] When the display parameters are adjusted from the display parameters corresponding to the 120HZ high refresh signal to the display parameters corresponding to the 240HZ high refresh signal and the display parameters are adjusted from the display parameters corresponding to the 144HZ high refresh signal to the display parameters corresponding to the 240HZ high refresh signal, the display device needs to turn on the HSR function. Figure 8 As shown, the process of adjusting the display parameters from the display parameters corresponding to the high refresh signal of 120HZ to the display parameters corresponding to the high refresh signal of 240HZ and the process of adjusting the display parameters from the display parameters corresponding to the high refresh signal of 144HZ to the display parameters corresponding to the high refresh signal of 240HZ are the same, both including: turning off the regional dimming function, turning off the variable refresh rate function, turning on the blackout function, sending an HSR function turn-on instruction to TCON, sending a VGH voltage rewrite instruction to the back-end PMU chip, sending a switching notification to the SOC, the switching notification indicates switching to the screen parameters corresponding to 240HZ, sending an adjustment notification to the application window, adjusting the size of the window, turning off the blackout function, and setting the gear corresponding to the regional dimming function.

[0184] When the display screen parameters are adjusted from the display screen parameters corresponding to the high refresh signal of 240HZ to the display screen parameters corresponding to the high refresh signal of 120HZ or the display screen parameters corresponding to the high refresh signal of 144HZ, such as Figure 8As shown, the display device first determines whether to cut in 120HZ or 144HZ. When cutting in 120HZ, the display device needs to read the status of the HSR function in the database. Then determine whether the status of the HSR function is on. When the status of the HSR function is on, the display device can keep the HSR function on, thereby adjusting the display parameters from the display parameters corresponding to the high refresh signal of 240HZ to the display parameters corresponding to the high refresh signal of 120HZ. When the status of the HSR function is off, the display device can turn off the regional dimming function, turn on the blackout function, send an instruction to turn off the HSR function to TCON, send an instruction to rewrite the VGH voltage to the back-end PMU chip, send a switching notification to the SOC, the switching notification indicates switching to the screen parameters corresponding to 120HZ, send an adjustment notification to the application window, adjust the size of the window, turn off the blackout function, and set the gear corresponding to the regional dimming function.

[0185] When switching to 144HZ, the display device can turn off the regional dimming function, turn on the blackout function, send an HSR function turn-off instruction to TCON, send a VGH voltage rewrite instruction to the back-end PMU chip, pull the HPD again, send a switching notification to the SOC, the switching notification indicates switching to the screen parameters corresponding to 144HZ, send an adjustment notification to the application window, adjust the window size, turn off the blackout function, and set the gear corresponding to the regional dimming function, thereby adjusting the display parameters from the display parameters corresponding to the high refresh signal of 240HZ to the display parameters corresponding to the high refresh signal of 144HZ.

[0186] For ease of understanding, the following Figure 9-14 The timing of switching between display screen parameters corresponding to a high refresh signal of 120HZ, display screen parameters corresponding to a high refresh signal of 144HZ, and display screen parameters corresponding to a high refresh signal of 240HZ in the display method provided in an embodiment of the present application is schematically illustrated.
