For example, "A or B" covers three schemes, namely, Scheme 1: including A but not including B; Scheme 2: including B but not including A; Scheme 3: including both A and B. The character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0044] In the technical solution of the present disclosure, words such as “connect”, “couple” or “connected” are not limited to physical or mechanical connections, but may include electrical connections.

[0045] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0046] The embodiment of the present invention provides a hardware super-resolution switching method, which is applied to a timing controller of a display module, see Figure 1 As shown, Figure 1 This is a flow chart of a method for switching hardware super-resolution according to an embodiment of the present invention, comprising:

[0047] Step S101: When the timing controller is connected to a source device, receiving information of a target resolution sent by the source device;

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

[0049] In the embodiment of the present invention, the timing controller (TCON) is an electronic component used in display technologies such as liquid crystal display (LCD) and organic light emitting diode (OLED). 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 present invention, the source device is a device that inputs video content to the display module, for example, a computer, a game console, a Blu-ray / DVD player, a streaming device, a smart phone and a tablet computer, a video camera and a digital camera, a webcam, and a media player.

[0051] In some embodiments of the present invention, the source device may be a graphics card (Graphics Card, also known as a graphics processor).

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

[0053] In an embodiment of the present invention, when a timing controller is connected to a source device, information on a target resolution sent by a source device is received; in response to the information on the target resolution, a display module is controlled to output a display image according to a target timing; wherein the target timing is a timing corresponding to the target resolution. When switching resolutions, the embodiment of the present invention does not require setting a special hardware HSR control signal or restarting the machine, thereby enabling efficient switching of display resolutions.

[0054] It should be noted that the existing switching method requires the setting of a hardware HSR control signal. Specifically, when the operating system is used for HSR switching, a hardware HSR control signal needs to be connected from the system end to the LCD display module, and the signal will be controlled by the system end and the LCD display module. Because both the system end and the LCD display module refer to the voltage of the signal, the voltage level needs to be precise, so the LCD display module with HSR function can only match the system end with HSR hardware control signal design, and the display module and the system end are strongly bound, and the versatility of the existing switching method is poor.

[0055] Based on this, in some embodiments of the present invention, optionally, information of the target resolution is included in the mainstream attribute information generated by the source device;

[0056] Receive the target resolution information sent by the source device, including:

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

[0058] Step b: Obtain target resolution information from mainstream attribute information.

[0059] In the embodiment of the present invention, the main stream attribute (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 an explanation with specific examples, see Figure 2 As shown, Figure 2 The figure is a flow chart for realizing display under the VESA standard, wherein the receiving device is equivalent to the display module in the embodiment of the present invention. After the source device and the receiving device are hot-plugged (step 1), the source device and the receiving device perform information exchange (steps 2 to 9), the source device sends MSA information (step 10) and video data (step 11) to the receiving device, and the receiving device performs display.

[0061] In actual applications, when the source device is combined with the display module and displays are realized, the source device sends mainstream attribute information to the display module according to the VESA (Video Electronics Standards Association) standard. Based on this, the embodiment of the present invention includes the target resolution information in the mainstream attribute information generated by the source device, and uses the existing VESA standard instructions to send the target resolution information to the timing controller of the display module. There is no need to configure the hardware HSR control signal design for the system, and the embodiment of the present invention has high versatility.

[0062] In some embodiments of the present invention, optionally, controlling the display module to output a display image according to a target timing sequence includes:

[0063] Step c: updating the current driving setting in the register of the timing controller to the target driving setting corresponding to the target resolution, and executing the target driving setting so that the display module outputs the display image according to the target timing.

[0064] It should be noted that the register of the timing controller pre-stores drive settings corresponding to multiple resolutions, and each drive setting corresponds to a different timing. In other words, the timing controller executes the drive setting, that is, the timing controller outputs a control signal to the display module according to the drive setting, and under the control of the control signal, the display module outputs a display screen according to the timing corresponding to the drive setting.

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

[0066] In an embodiment of the present invention, controlling the display module to output a display image according to a target timing sequence includes:

[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 so that the display module outputs the display image according to the target timing. The embodiment of the present invention can improve the switching efficiency.

[0068] In some embodiments of the present invention, optionally, controlling the display module to output a display image according to a target timing sequence includes:

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

[0070] The current drive setting in the register of the timing controller is updated to the target drive setting corresponding to the target resolution, and then includes:

[0071] Step e: Exit the built-in self-test mode, execute the target drive setting, and make the display module output the display image according to the target timing.

[0072] Built-In Self-Test (BIST) mode is a technology used 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 device without external test equipment.

[0073] Specifically in the embodiment of the present invention, when entering the built-in self-test mode of the timing controller, the display module outputs a preset BIST black screen with the existing timing. After exiting the built-in self-test mode, the display outputs the BIST black screen with 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. There is no difference in this process phenomenon, and the user is easy to adapt, that is, the smoothness of the switching transition between different resolutions is improved, and the user experience is improved. After that, the video data sent by the source device is received, and the video data is then displayed with the target timing.

[0074] The embodiment of the present invention provides a hardware super-resolution switching method, which is applied to a source device, see Figure 3 As shown, Figure 3 The second flowchart of the method for switching hardware super-resolution according to an embodiment of the present invention includes:

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

[0076] Step S202: When the source device is connected to the timing controller of the display module, information of the target resolution is sent to the timing controller so that the timing controller controls the display module to output a display image according to the target timing, wherein the target timing is a timing corresponding to the target resolution.

[0077] In the embodiment of the present invention, step S201 may specifically be: Figure 4 As shown, the user selects the desired resolution on the display module resolution adjustment page through the interactive terminal, or, see Figure 5As shown, the user selects the desired resolution on the output resolution adjustment page of the graphics card control menu through the interactive terminal. Further, through step S202, when the source device is connected to the timing controller of the display module, the source device sends the target resolution information to the timing controller. In response to the target resolution information, the timing controller controls the display module to output the display screen according to the target timing; wherein the target timing is the timing corresponding to the target resolution.

[0078] In the embodiment of the present invention, step S201: receiving information of the target resolution sent by the user through the interactive terminal; step S202: when the source device is connected to the timing controller of the display module, sending information of the target resolution to the timing controller, so that the timing controller controls the display module to output the display screen according to the target timing, wherein the target timing is the timing corresponding to the target resolution. The embodiment of the present invention can conveniently switch the display resolution with high switching efficiency.

[0079] The following is described in conjunction with specific embodiments:

[0080] See also Figure 6 As shown, Figure 6 This is a schematic diagram of the hardware super-resolution switching process, where the timings ① and ② involved are described as follows:

[0081] Timing①: HSR off: 2560*1600 240Hz;

[0082] Timing ②: HSR on: 1280*800 480Hz, timing ① and ② are different except for the Tx driver timing, the EDID & DPCD transmitted to the graphics card includes both HSR on and HSR off settings. It indicates that HSR off is switched to HSR on, and vice versa.

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

[0084] A. User switching resolution: see Figure 4 and Figure 5 As shown, the user selects different resolutions in the actual settings or graphics card control panel interface;

[0085] B. Graphics card link training: When the graphics card is restarted, it has already obtained the EDID & DPCD information of the display module (corresponding to Figure 2 When the graphics card switches the resolution, it will re-link the module until the MSA information is sent (corresponding to Figure 2 Steps 7-10);

[0086] C. During the training process between the timing controller and the graphics card, TX (the transmitting electrode of the display module) outputs the BIST black screen at the timing ①;

[0087] D. Identify resolution and determine HSR status: The timing controller interprets the resolution information through the MSA information to determine the switch status of the HSR requirement;

[0088] E. Timing control switching: After sending the MSA information, the graphics card enters the video data transmission. At this time, the timing controller updates the corresponding timing. 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 the BIST black screen.

[0089] F. Timing control switching: After the timing controller completes the timing update, Tx switches to the new timing to output the BIST black 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 completed: HSR switch switching is completed.
