[0024] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0025] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0026] The main solution of the embodiment of the present application is: obtaining the resolution switching information of the display screen; determining the target refresh rate and target resolution corresponding to the resolution switching information, and transmitting the target resolution to the signal source; receiving the image signal of the target resolution transmitted by the signal source, and displaying the image signal based on the target refresh rate.

[0027] Since the high-performance display screen and driving motherboard used in the prior art are limited by the signal source, it is impossible to achieve high refresh rate display on a high-resolution display.

[0028] The present application provides a solution that can first obtain the resolution switching information of the display screen; determine the target refresh rate and target resolution corresponding to the resolution switching information, and receive the image signal of the target resolution transmitted by the signal source based on the target resolution, thereby solving the technical problem in the prior art that the resolution and refresh rate cannot be switched synchronously, affecting the user experience.

[0029] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device capable of implementing the above functions, a resolution switching device, etc. The following uses a resolution switching device as an example (hereinafter referred to as the device) to illustrate this embodiment and the following embodiments.

[0030] Based on this, the embodiment of the present application provides a resolution switching method, referring to Figure 1 , Figure 1 This is a flowchart of the first embodiment of the resolution switching method of the present application.

[0031] In this embodiment, the resolution switching method includes steps S10 to S30:

[0032] Step S10: Acquire the resolution switching information of the display screen.

[0033] It should be noted that the resolution switching information can be parameter information used to instruct the display screen to switch between different display modes (such as high resolution and low refresh rate / low resolution and high refresh rate). The resolution switching information can include a set number mark bit, a target resolution and a target refresh rate. Among them, the set number mark bit can be used to identify the status bit of the current target mode. For example, two marks of "1" and "0" can be used. When the value of the set number mark bit is "0", it can indicate that the target mode of the corresponding display screen is high resolution and low refresh rate. When the value of the set number mark bit is "1", it can indicate that the target mode of the corresponding display screen is low resolution and high refresh rate.

[0034] It should be understood that the resolution switching information can be generated by manual or automatic triggering. The user can generate a switching instruction through the monitor's physical buttons (such as the "mode switch key"), the on-screen display menu (OSD) or an external device (such as a keyboard shortcut), and input the switching instruction to the device via wireless or wired transmission. The device can read the instruction and call the resolution switching information when receiving the switching instruction. The resolution switching information can also be automatically generated when conditions such as game running or insufficient bandwidth are detected.

[0035] Step S20: determining the target refresh rate and target resolution corresponding to the resolution switching information, and transmitting the target resolution to the signal source.

[0036] It should be noted that the target mode of the display screen can be determined by the set flag bit of the resolution switching information. For example, when the value of the set flag bit is "0", the corresponding target resolution is 3840×2160 and the corresponding target refresh rate is 60Hz; when the value of the set flag bit is "1", the corresponding resolution is 1920×1080 and the corresponding target refresh rate is 120Hz. The processor reads the current set flag bit state through the register and stores a mapping table of the relationship between the set flag bit, the target resolution, and the target refresh rate in the memory. The corresponding row data is extracted from the mapping table according to the set flag bit to obtain the corresponding target refresh rate and target resolution.

[0037] Furthermore, after the display switches to the target mode, the corresponding target resolution and target refresh rate combination must ensure that the total bandwidth remains within the supported range of the hardware interface. For example, in high-resolution, low-refresh-rate mode (3840×2160@60Hz) and low-resolution, high-refresh-rate mode (1920×1080@120Hz), the resolution is reduced to 1 / 4, the refresh rate is increased by 2 times, and the total bandwidth is close. That is, before and after the display switches, the H and V values of its resolution can be divided by 2, and the refresh rate can be multiplied by 2 or higher (based on the maximum refresh rate of the display). For example, 5120×2160@X(Hz) can be switched to 3560×1080@X*2(Hz); 7680×2160@X(Hz) can be achieved at 3840×1080@X*2(Hz), and so on.

[0038] It should be understood that the signal source can be a device that provides image signal input to the display screen, capable of generating, processing and transmitting image data to the display screen so that the display screen can display a specific image. The signal source can read the extended display identification data (EDID) of the display screen through the display data channel (DDC), thereby realizing the function of obtaining the target resolution. The EDID data structure can encode the target resolution and target refresh rate into 128 bytes of data. Specifically, the pixel clock frequency can be calculated based on the target resolution and target refresh rate, and a digital signal can be generated by performing timing synchronization.

[0039] Step S30: receiving an image signal of a target resolution transmitted by a signal source, and displaying the image signal based on a target refresh rate.

[0040] It should be noted that the image signal transmitted by the signal source can be received through the HDMI interface. Since the EDID data structure received by the signal source contains the target resolution, the resolution of the generated image signal is the target resolution. After receiving the switched image signal, its pixel data and synchronization signal can be separated and stored in the cache area. The synchronization signal is processed according to the target refresh rate to generate a driving waveform frequency corresponding to the target refresh rate, and the driving waveform frequency is used to drive the pixel data of the image signal for display, thereby displaying the image signal of the target resolution based on the target refresh rate.

[0041] This embodiment provides a resolution switching method, which discloses obtaining resolution switching information of a display screen; determining a target refresh rate and a target resolution corresponding to the resolution switching information, and transmitting the target resolution to a signal source; receiving an image signal of the target resolution transmitted by the signal source, and displaying the image signal based on the target refresh rate. Since this embodiment can first obtain the resolution switching information of the display screen; determine the target refresh rate and the target resolution corresponding to the resolution switching information, and receive the image signal of the target resolution transmitted by the signal source based on the target resolution, the technical problem in the prior art that the resolution and refresh rate cannot be switched synchronously and affects the user experience is solved.

[0042] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above embodiment 1 can be referred to the above introduction and will not be described in detail later. Figure 2 , Figure 2 This is a first flow chart provided for the second embodiment of the resolution switching method of the present application.

[0043] In this embodiment, step S20 includes steps S201 to S203:

[0044] Step S201: When the set flag of the resolution switching information is a low resolution flag, the target refresh rate is set to the first refresh rate, and the target resolution is set to the first resolution.

[0045] It should be noted that the low-resolution mark can be a status flag in the resolution switching information indicating that the display screen currently needs to switch to the "low-resolution high refresh rate" mode. It can be used as a collaborative switch for hardware and software to trigger the linkage adjustment of resolution, refresh rate, EDID parameters and screen parameter control signals. The first refresh rate and the first resolution are the target refresh rate and target resolution bound to the low-resolution mark, that is, the refresh rate and resolution in the low-resolution high refresh rate mode. For example, 120Hz and 1920×1080. The first refresh rate and the first resolution must meet the bandwidth balance so that the total amount of data transmitted is close.

[0046] Step S202: setting extended display identification data of the display screen according to the first resolution.

[0047] Step S203: Transmitting the extended display identification data to the signal source.

[0048] It should be noted that the first resolution can be encoded in the extended display identification data by converting it into a pixel clock. The EDID can also include relevant information such as a product code and serial number to facilitate device transmission. The device processor can transmit the generated EDID to the signal source via a DDC communication line. This allows the display to switch from a high-resolution, low-refresh-rate display mode to a low-resolution, high-refresh-rate display mode.

[0049] Reference Figure 3 , Figure 3 This is a second flow chart of the second embodiment of the resolution switching method of this application. Step S20 also includes steps S301 to S303:

[0050] Step S301: When the set flag of the resolution switching information is a high-resolution flag, the target refresh rate is set to the second refresh rate, and the target resolution is set to the second resolution.

[0051] It should be noted that the high-resolution flag can be a status flag in the resolution switching information indicating that the display needs to switch to "high-resolution, low-refresh-rate" mode. The second refresh rate and second resolution are the target refresh rate and target resolution associated with the high-resolution flag, i.e., the refresh rate and resolution in high-resolution, low-refresh-rate mode. For example, 60Hz and 3840×2160 are used. The second refresh rate is lower than the first refresh rate, and the second resolution is higher than the first resolution.

[0052] Step S302: setting extended display identification data of the display screen according to the second resolution.

[0053] Step S303: Transmitting the extended display identification data to the signal source.

[0054] It should be noted that the second resolution can be encoded in the extended display identification data by converting it into a pixel clock. The generated EDID is sent to the signal source via the DDC communication line, thereby enabling the display screen to switch from a low-resolution, high-refresh-rate display mode to a high-resolution, low-refresh-rate display mode.

[0055] It should be understood that the FreeSync function and the Sharpness function can also be set in the EDID. The FreeSync function can eliminate display tearing, freezes and input delays by dynamically synchronizing the monitor refresh rate with the graphics card output frame rate, thereby providing a smooth visual experience. The Sharpness function is a picture quality adjustment function in the display or image processing. It can make the picture details sharper and the contours clearer by enhancing the contrast of the image edges. In specific implementation, the FreeSync function and the Sharpness function can be turned off in the high-resolution and low-refresh-rate mode, and turned on in the low-resolution and high-refresh-rate mode.

[0056] Further, you can refer to Figure 4 , Figure 4 This is a third flow chart of the second embodiment of the resolution switching method of this application. Step S30 includes steps S401 to S403:

[0057] Step S401: upon receiving an image signal of a target resolution transmitted by a signal source, stop outputting a power supply signal to the display screen.

[0058] It should be noted that the device may include a power management module, which can be used to generate the power supply signal required by the display and receive processor control instructions to dynamically cut off / restore power. When the processor detects a resolution switching requirement, specifically a change in the resolution of the image signal received from the signal source, it can send a control instruction to the power management module to "stop power supply."

[0059] Step S402: setting the refresh rate of the image signal to the target refresh rate, and generating a power supply signal to drive the display screen to light up.

[0060] Step S403: transmitting the image signal to the display screen, and displaying the image signal based on the target refresh rate.

[0061] It should be noted that the display's resolution, refresh rate and other screen parameters are stored in the non-volatile registers of the logic board, and the data will be cleared after power failure. If the power is not cut off, the old screen parameters (before switching the resolution) will remain in the register, causing the new screen parameters to fail to load correctly, resulting in abnormal display conditions, so it is necessary to adjust the corresponding screen parameters after power failure. The pixel data and synchronization signal can be separated after the image signal, and the synchronization signal is stored in the cache. After the power management module stops supplying power, the target refresh rate is written to the cache, the frequency of the synchronization signal is adjusted, and the refresh rate of the image signal is adjusted to the target refresh rate. After the adjustment is completed, the power management module resumes power supply in sequence, regenerates the power supply signal, and then drives the display screen to light up.

[0062] It should be understood that a screen parameter adjustment signal of a corresponding level can be generated at the mode selection pin (Mede SEL) according to the target resolution of the image signal; when the screen parameter adjustment signal is a high-level signal, the refresh rate of the image signal is set to the first refresh rate, and when the screen parameter adjustment signal is a low-level signal, the refresh rate of the image signal is set to the second refresh rate. In the low-resolution and high-refresh-rate mode, the Mede SEL pin remains at a high level during the screen initialization sequence, and in the high-resolution and low-refresh-rate mode, the Mede SEL pin remains at a low level during the screen initialization sequence. After detecting the high-level screen parameter adjustment signal, the first refresh rate is written to the register in the buffer area.

[0063] In a possible implementation, the image signal may be subjected to frame extraction processing to obtain a frame extraction signal, and the target refresh rate may be subjected to frequency multiplication processing to obtain a doubled refresh rate; and the frame extraction signal may be displayed based on the doubled refresh rate.

[0064] It should be noted that frame extraction refers to selecting some frames from the original image signal sequence according to certain rules as a new image frame extraction sequence. For example, to halve the frame rate, select one frame every other frame. The frame extraction interval is determined according to requirements. The selected frames are combined into a new image sequence, namely the frame extraction signal. Frequency doubling is to multiply the target refresh rate by a multiple to obtain the doubled refresh rate. The frequency doubling multiple is determined according to requirements. For example, to double the refresh rate, the frequency doubling factor is 2; to triple the original rate, the frequency doubling factor is 3. Multiply the target refresh rate by the frequency doubling factor to obtain the doubled refresh rate.

[0065] This embodiment discloses how to determine the target resolution and target refresh rate, set the extended display identification data of the display screen according to the target refresh rate, and transmit the extended display identification data to the signal source. When receiving the image signal of the target resolution transmitted by the signal source, stop outputting the power signal to the display screen; set the refresh rate of the image signal to the target refresh rate, generate a power signal to drive and light up the display screen; transmit the image signal to the display screen, and display the image signal based on the target refresh rate. Through the coordination of software and hardware, precise control of resolution and refresh rate is achieved, ensuring that the resolution and refresh rate of input and output remain consistent. Users can intuitively view the actual refresh rate in the system settings to avoid misjudging the actual working status.

[0066] Based on the first embodiment and / or the second embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those in the above embodiments can be referred to the above introduction and will not be described in detail later. Figure 5 , Figure 5 This is a flowchart of the third embodiment of the resolution switching method of this application.

[0067] In this embodiment, step S10 includes steps S501 to S503:

[0068] Step S501: collecting the triggering duration of the switching trigger signal.

[0069] It should be noted that the switching trigger signal can be a signal that triggers a resolution switching operation and can be generated in a variety of ways, such as a user pressing a specific physical button, a command issued through a software interface, or a specific state change detected by a sensor. In this embodiment, when a user presses the "Mode Switch" button, the electrical signal generated by this button can serve as the switching trigger signal. The trigger duration can be the length of time from the start of the switching trigger signal to the end of the triggering process. If the user presses and holds the button, the time elapsed from the moment the button is pressed to the moment it is released is the trigger duration.

[0070] Step S502: When the trigger duration exceeds the switching threshold time, the set flag bit of the resolution switching information is inverted and adjusted.

[0071] It should be noted that the switching threshold time can be a preset time value for determining whether to perform a resolution switching operation. When the trigger duration exceeds this time value, subsequent resolution switching related operations will be performed. For example, the switching threshold time can be set to 3 seconds. When the trigger duration exceeds 3 seconds, the corresponding resolution switching process will be performed.

[0072] Step S503: obtaining resolution switching information after the set flag is inverted and adjusted.

[0073] It should be noted that the set flag bit in the resolution switching information can contain "0" or "1". When the set flag bit is 0, it indicates switching to a low-resolution, high-refresh-rate mode. When the set flag bit is 1, it indicates switching to a high-resolution, low-refresh-rate mode. Reverse the current value of the set flag bit. If the set flag bit is currently 0, it will become 1 after inversion; if it is currently 1, it will become 0 after inversion. In this way, the resolution mode is switched. When the trigger duration of the switching trigger signal exceeds the switching threshold time, the set flag bit will be inverted, thereby achieving the switching adjustment of the resolution mode.

[0074] In this embodiment, the trigger duration of the acquisition switching trigger signal is disclosed. When the trigger duration exceeds the switching threshold time, the set flag bit of the resolution switching information is inverted and adjusted. The resolution switching information after the set flag bit is inverted and adjusted is obtained. By acquiring the trigger duration of the switching trigger signal and comparing it with the switching threshold to determine whether to invert the set flag bit, the resolution switching adjustment can be flexibly performed. Compared with the traditional method of switching modes through complex menu settings, this method saves time, improves usage efficiency, can meet the usage requirements of different users in different scenarios, and improves the versatility and applicability of the device.

[0075] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the resolution switching method of the present application.
