In addition, "or" in the present application means at least one of the connected objects. For example, "A or B" covers three schemes, namely, scheme one: including A and not including B; scheme two: including B and not including A; scheme three: including A and including B. The character " / " generally represents that the objects before and after are in an "or" relationship.

[0044] In the technical solutions of the present disclosure, the terms such as "connection", "coupling" or "connection" are not limited to physical or mechanical connection, but can include electrical connection.

[0045] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as there is no conflict.

[0046] The embodiment of the application provides a hardware super-resolution switching method, which is applied to a timing controller of a display module. Figure 1 As shown in the figure, Figure 1 It is one of the flowcharts of the hardware super-resolution switching method of the embodiment of the application, which comprises the following steps:

[0047] Step S101: In the case that the timing controller is connected with a source device, information of a target resolution sent by the source device is received.

[0048] Step S102: In response to the information of the target resolution, the display module is controlled to output a display picture according to a target timing; wherein the target timing is a timing corresponding to the target resolution.

[0049] In the embodiment of the application, the timing controller (TCON) is an electronic component for display technologies such as liquid crystal display (LCD) and organic light-emitting diode (OLED). The TCON is used to control the timing and signal of the display module to ensure the correct display of the image.

[0050] In the embodiment of the application, the source device is a device for inputting video content to the display module. For example, a computer, a game console, a Blu-ray / DVD player, a streaming media device, a smart phone and a tablet computer, a video camera and a digital camera, a network camera, a media player.

[0051] In some embodiments of the application, the source device can be a graphics card (also known as a graphics processor).

[0052] In the embodiment of the application, the mapping relationship data of the timing-resolution is pre-stored in the timing controller. In step S102, after the target resolution is received, the target timing corresponding to the target resolution can be determined according to the mapping relationship data of the timing-resolution.

[0053] In the embodiment of the present application, by connecting the timing controller with the source device, the information of the target resolution sent by the source device is received; in response to the information of the target resolution, the display module is controlled to output the display picture according to the target timing; wherein the target timing is the timing corresponding to the target resolution, the embodiment of the present application does not need to set a special hardware HSR control signal when switching the resolution, and does not need to restart the machine, and can realize efficient switching of the display resolution.

[0054] It should be noted that the existing switching method needs to set a hardware HSR control signal, specifically, when the operating system is used for HSR switching, the hardware HSR control signal needs to be connected from the system end to the liquid crystal display module, and the signal is jointly controlled by the system end and the liquid crystal display module. Because the system end and the liquid crystal display module both refer to the voltage of the signal, the voltage level needs to be accurate, so the liquid crystal display module with HSR function can only match the system end with HSR hardware control signal design, the display module and the system end are strongly bound, and the existing switching method has poor universality.

[0055] Based on this, in some embodiments of the present application, the information of the target resolution is contained in the main stream attribute information generated by the source device.

[0056] The information of the target resolution sent by the source device is received, including:

[0057] Step a: receiving the main stream attribute information sent by the source device;

[0058] Step b: obtaining the information of the target resolution from the main stream attribute information.

[0059] In the embodiment of the present application, the main stream attribute (Main Stream Attribute, English abbreviation MSA) information refers to the characteristics and parameters used to describe the main stream (or main video stream) in video transmission and display, especially in DisplayPort or other video interface standards. These characteristics and parameters define the basic settings and functions of the video stream to ensure that the video signal can be correctly transmitted and displayed.

[0060] The following is described in combination with a specific example, referring to Figure 2 As shown, Figure 2 It is a flowchart for realizing display under the VESA standard, wherein the receiving device can be equivalent to the display module in the embodiment of the present application, after the source device and the receiving device are hot plugged (step 1), the source device and the receiving device interact information (steps 2 to 9), the source device sends the MSA information to the receiving device (step 10) and sends the video data (step 11), and the receiving device displays.

[0061] In actual application, in the process that the source device is combined with the display module and realizes display, according to the VESA (Video Electronics Standards Association, Chinese means: Video Electronics Standards Association) standard, the source device sends the main stream attribute information to the display module. Based on this, the embodiment of the application includes the information of the target resolution in the main stream attribute information generated by the source device, and sends the information of the target resolution to the timing controller of the display module by using the existing standard instruction of VESA, without the design of the hardware HSR control signal corresponding to the system, and the embodiment of the application has high universality.

[0062] In some embodiments of the application, optionally, the display module is controlled to output the display picture according to the target timing, comprising:

[0063] Step c: updating the current drive setting in the register of the timing controller to the target drive setting corresponding to the target resolution, and executing the target drive setting to make the display module output the display picture according to the target timing.

[0064] It should be noted that the register of the timing controller pre-stores the drive setting corresponding to the plurality of resolutions one by one, and the drive setting corresponds to different timing respectively. That is, the timing controller executes the drive setting, that is, the timing controller outputs the control signal to the display module according to the drive setting, and the display module outputs the display picture according to the timing corresponding to the drive setting under the control of the control signal.

[0065] Specifically, in the embodiment of the application, updating the current drive setting in the register of the timing controller to the target drive setting corresponding to the target resolution can include: determining the drive setting corresponding to the target resolution stored in the register as the target drive setting according to the target resolution; updating the current drive setting with the target drive setting, so that the timing control calls the target drive setting when outputting the control signal to the display module.

[0066] In the embodiment of the application, the display module is controlled to output the display picture according to the target timing, comprising:

[0067] Step c: updating the current drive setting in the register of the timing controller to the target drive setting corresponding to the target resolution, and executing the target drive setting to make the display module output the display picture according to the target timing, which can improve the switching efficiency.

[0068] In some embodiments of the application, optionally, the display module is controlled to output the display picture according to the target timing, comprising:

[0069] Step d: entering the built-in self-test mode of the timing controller according to the current timing;

[0070] updating the current drive setting in the register of the timing controller to a target drive setting corresponding to the target resolution, and then comprising:

[0071] Step e: exiting the built-in self-test mode, executing the target drive setting, and causing the display module to output a display picture according to the target timing.

[0072] The built-in self-test (BIST) mode is a technology for self-diagnosis and testing of hardware devices. It is usually applied to electronic devices, integrated circuits and systems to automatically detect and verify the functions and performance of the devices without external testing devices.

[0073] In the embodiment of the present application, when entering the built-in self-test mode of the timing controller, the display module outputs a preset BIST black picture according to the existing timing. After exiting the built-in self-test mode, the display outputs the BIST black picture according to the new timing (i.e. the target timing). The Windows system and the graphics card are originally in a black screen state when switching the refresh rate, and there is no difference in this process. Therefore, the user is easy to adapt, and the smoothness of the switching transition between different resolutions is improved, and the user experience is improved. Thereafter, the video data sent by the source device is received, and the video data is displayed according to the target timing.

[0074] The embodiment of the present application provides a switching method of hardware super resolution, which is applied to a source device, as shown in Figure 3 The flowchart of the switching method of hardware super resolution of the embodiment of the present application is shown in Figure 3 The flowchart of the switching method of hardware super resolution of the embodiment of the present application is shown in

[0075] Step S201: receiving information of a target resolution sent by a user through an interactive terminal;

[0076] Step S202: in the case that the source device is connected with the timing controller of the display module, sending the information of the target resolution to the timing controller, so that the timing controller controls the display module to output a display picture according to a target timing, wherein the target timing is a timing corresponding to the target resolution.

[0077] In the embodiment of the present application, step S201 can be, as shown in Figure 4 The user selects a required resolution through a resolution adjustment page of the display module through the interactive terminal, or as shown in Figure 5As shown, the user selects the required resolution through the output resolution adjustment page of the graphic card control menu. Further, in the case that the source device is connected to the timing controller of the display module, the source device sends the information of the target resolution to the timing controller through step S202. The timing controller controls the display module to output the display picture according to the target timing in response to the information of the target resolution; wherein the target timing is the timing corresponding to the target resolution.

[0078] In the embodiment of the present application, the information of the target resolution sent by the user through the interactive terminal is received through step S201; and in the case that the source device is connected to the timing controller of the display module, the information of the target resolution is sent to the timing controller through step S202, so that the timing controller controls the display module to output the display picture according to the target timing, wherein the target timing is the timing corresponding to the target resolution. The embodiment of the present application can conveniently switch the display resolution with high efficiency.

[0079] The following will be described in combination with specific embodiments:

[0080] Referring to Figure 6 As shown, Figure 6 The figure is a schematic diagram of the hardware super resolution switching process, wherein the timings ① and ② are explained as follows:

[0081] Timing ①: HSR off: 2560*1600 240Hz;

[0082] Timing ②: HSR on: 1280*800 480Hz. The EDID&DPCD transmitted to the graphic card includes the HSR on and HSR off settings. The switching from HSR off to HSR on is illustrated, and vice versa.

[0083] Referring to Figure 6 As shown, the switching steps include:

[0084] A. User switches the resolution: referring to Figure 4 and Figure 5 As shown, the user selects different resolutions in the real setting or the graphic card control panel interface;

[0085] B. Graphic card link training: the graphic card has obtained the EDID&DPCD information of the display module when it is restarted (corresponding to steps 1-6 in Figure 2 ). The graphic card will re-perform the link training with the module when switching the resolution, until the MSA information is sent (corresponding to steps 7-10 in Figure 2 );

[0086] C. During the training process with the graphics card, the timing controller outputs a BIST black screen at timing ① (TX, the emitter electrode of the display module).

[0087] D. Identify resolution and determine HSR status: The timing controller interprets the resolution information through MSA information to determine the on / off status of HSR requirements;

[0088] E. Timing control switching: After the graphics card sends the MSA information, it enters the video data transmission. At this time, the timing controller updates the timing accordingly. However, before the update is completed, Rx (the sensing electrode of the display module) continues to receive the video data sent by the graphics card, but Tx still maintains the original timing to output a BIST black screen.

[0089] F. Timing control switching: After the timing controller completes the timing update, Tx switches to the new timing output to display a black BIST screen;

[0090] G. Timing control switching: The timing controller exits the built-in self-test mode, and Tx outputs the graphics card screen with the new timing;

[0091] H, HSR switching complete: HSR switch switching complete.
