[0027] The features and exemplary embodiments of various aspects of the present application will be described in detail below. To make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present application by showing examples of the present application.

[0028] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the said element.

[0029] It should be understood that the term "and / or" used in this text is only a relational term describing the associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " in this text generally indicates that the associated objects before and after are in an "or" relationship.

[0030] It should be noted that the transistors in the embodiments of this application may be N-type transistors or P-type transistors. For an N-type transistor, the conduction level is a high level and the cut-off level is a low level. That is, when the gate of the N-type transistor is at a high level, its first and second poles are conducting, and when the gate of the N-type transistor is at a low level, its first and second poles are turned off. For a P-type transistor, the conduction level is a low level and the cut-off level is a high level. That is, when the control electrode of the P-type transistor is at a low level, its first and second poles are conducting, and when the control terminal of the P-type transistor is at a high level, its first and second poles are turned off. In specific implementation, the gate of each of the above transistors serves as its control electrode, and according to the signal of the gate of each transistor and its type, its first pole can be used as the source electrode and the second pole as the drain electrode, or its first pole can be used as the drain electrode and the second pole as the source electrode, without distinction here. Additionally, the conduction level and cut-off level in the embodiments of the present invention are both general terms. The conduction level refers to any level that can make the transistor conduct, and the cut-off level refers to any level that can make the transistor cut off / turn off.

[0031] In the embodiments of this application, the term "electrically connected" may mean that two components are directly electrically connected, or it may mean that two components are electrically connected via one or more other components.

[0032] In the embodiments of this application, the first node, the second node, and the third node are only defined for the convenience of describing the circuit structure, and the first node, the second node, and the third node are not an actual circuit unit.

[0033] Without departing from the spirit or scope of the present application, various modifications and variations can be made in the present application, which will be obvious to those skilled in the art. Therefore, the present application is intended to cover the modifications and variations of the present application that fall within the scope of the corresponding claims (claimed technical solutions) and their equivalents. It should be noted that the embodiments provided in the present application can be combined with each other without conflict.

[0034] Before elaborating on the technical solutions provided in the embodiments of the present application, for the convenience of understanding the embodiments of the present application, the present application first specifically describes the problems existing in the related technologies:

[0035] As mentioned above, with the continuous development of display technologies, the functions integrated in display panels are becoming increasingly numerous. Taking the Incell Touch Display technology as an example, this technology integrates the touch sensor function into the liquid crystal display (LCD). Specifically, this technology multiplexes the common electrode as the touch electrode. During the display stage, a common voltage signal is input to the common electrode, and an electric field is formed between the common electrode and the pixel electrode, thereby controlling the deflection of the liquid crystal to achieve the display of the picture. During the touch stage: the common electrode is multiplexed as the touch electrode. When the user touches the screen, the electric field distribution on the touch electrode will change, thereby causing a voltage change. By detecting these voltage changes through a touch chip, the touch position can be identified. This integration method enables the touch function and the display function to be closely combined, thereby making the entire display screen thinner and lighter, reducing the thickness and weight of the screen. Based on the above advantages, the Incell Touch Display technology is widely used in modern electronic devices, including smartphones, tablet computers, and laptop computers, etc.

[0036] However, the inventors of the present application have found that at the present stage, for the in-cell touch display panel adopting the above-mentioned Incell Touch Display technology, during the operation of such a display panel, it is difficult to effectively improve the refresh rate in high-refresh-rate demand scenarios such as the game mode or movie playback display. Therefore, there is a problem of a low refresh rate of the display screen. As a result, the user experience in the game mode is poor, the product quality of the display panel is reduced, and it is difficult to meet the market's high-refresh-rate performance requirements for the display panel.

[0037] In view of the above, the embodiments of the present application provide a display device and a driving method of the display device, which can solve the technical problem that it is difficult to effectively improve the refresh rate of the in-cell touch function display panel existing in the related technologies.

[0038] First, the display device 100 provided in the embodiments of the present application will be introduced below. First, please refer toFigure 1 , Figure 1 is a schematic structural diagram of a display device 100 provided by an embodiment of the present application. It can be understood that the display device 100 provided by the embodiment of the present application can be a wearable product, a computer, a television, a vehicle-mounted display device 100, or other display devices 100 with a display function. The present application does not make specific limitations on this.

[0039] As Figure 1 shown, the display panel 30 in the display device 100 is a display panel 30 with an in-plane touch function. The display device 100 includes:

[0040] A data storage chip 10 stores pre-set first firmware resources and second firmware resources. The first firmware resources include first timing parameters of the display panel 30 in a first mode, and the second firmware resources include second timing parameters of the display panel 30 in a second mode;

[0041] A timing controller 20 is configured to download the first firmware resources from the data storage chip 10 and output the first timing parameters according to the first firmware resources when the display panel 30 is configured in the first mode;

[0042] When the display panel 30 is configured in the second mode, download the second firmware resources from the data storage chip 10 and output the second timing parameters according to the second firmware resources;

[0043] Among them, within one frame display cycle of the display panel 30, the first timing parameters include display timing parameters and touch timing parameters, and the second timing parameters include display timing parameters. The frequency of the display timing parameters in the second timing parameters is higher than the frequency of the display timing parameters in the first timing parameters.

[0044] In the present application, the display device 100 is, for example, a smart phone, a tablet computer, and a notebook computer, etc. The display panel 30 with an in-plane touch function in the display device 100 can be understood as a display panel 30 adopting Incell Touch Display technology. The display panel 30 is, for example, an LCD panel, and no strict limitation is made here.

[0045] Specifically, the above-mentioned first mode can correspond to a display scenario with a low refresh rate. For example, a display scenario where the display panel 30 needs to statically display static pictures or text information. In this display scenario, the display panel 30 is displayed according to the first mode, which is beneficial to reducing power consumption through a low refresh rate.

[0046] Specifically, the above-mentioned second mode may correspond to a display scenario with a high refresh rate. For example, it is a display scenario where the display panel 30 needs to display dynamic content, such as scenarios like e-sports games, live broadcasts, and movie playback. In this display scenario, the display panel 30 displays according to the second mode to achieve a high refresh rate. A high-refresh-rate screen can significantly reduce motion blur and blurring phenomena, thereby providing a smoother visual experience and fully meeting the user experience requirements.

[0047] In the display device 100, the above-mentioned data storage chip 10 is mainly responsible for storing display-related data, such as compensation data, image data, etc., to ensure the accuracy and stability of the display effect.

[0048] The data storage chip 10 can be, for example, EEPROM (Electrically Erasable Programmable Read-Only Memory), NOR Flash, NAND Flash, SRAM (Static Random Access Memory), etc., and can be specifically selected according to its characteristics to ensure high-quality and stable display effects.

[0049] The timing controller 20 (TCON, Timing Controller) can be used to manage the timing control of pixel data to ensure that the display content can be correctly presented. Before the timing controller 20 works, the data storage chip 10 needs to provide the corresponding firmware resources to the timing controller 20, and then the timing controller 20 can output the corresponding control signals and data signals to the screen driver according to the correct required timing. When the user has different display requirements, such as when the resolution, refresh rate, and color mode need to be adjusted, the timing controller 20 will correspondingly adjust its output signals and control logic to make the display effect meet the expectations.

[0050] The data storage chip 10 and the timing controller 20 can be communicatively connected to enable the timing controller 20 to read and download the firmware resources in the data storage chip 10. In one example, after the timing controller 20 is powered on and stabilized, the firmware resources in the data storage chip 10 can be read through the I2C (Inter-Integrated Circuit) bus. The firmware resources include the program resources required for the initialization of the timing controller 20, such as timing parameters, calibration data, etc.

[0051] In the present application, specifically in implementation, when the display panel 30 is configured in the first mode, the timing controller 20 downloads the first firmware resource corresponding to the first mode from the data storage chip 10 and outputs the first timing parameters according to the first firmware resource.

[0052] When the display panel 30 is configured in the second mode, the timing controller 20 downloads the second firmware resource from the data storage chip 10 and outputs the second timing parameters according to the second firmware resource. The above first timing parameters and second timing parameters can be used to configure the internal registers and working modes of the timing controller 20 to ensure that the timing controller 20 can correctly generate control signals and data signals.

[0053] In this way, by loading the firmware resources corresponding to different modes from the data storage chip 10 by the timing controller 20, the switching of the timing parameters in the normal display scenario and the high-refresh display scenario can be quickly and efficiently realized, so as to effectively realize the mode switching of the display panel 30 between the first mode and the second mode.

[0054] Moreover, in the embodiments of the present application, within one frame display period of the display panel 30, the first timing parameters corresponding to the first mode include display timing parameters and touch control timing parameters, so as to ensure that the display panel 30 with in-plane touch control function can display and touch sense normally. The second timing parameters include display timing parameters, and the frequency of the display timing parameters in the second timing parameters is higher than that of the display timing parameters in the first timing parameters to ensure the high-refresh display of the display panel 30, so as to fully meet the high-refresh display requirements of users in scenarios such as games, and further improve the product competitiveness of the display device.

[0055] Please refer to the following Figure 2 , Figure 2 which is a schematic structural diagram of another display device 100 provided by the embodiments of the present application. According to some embodiments of the present application, optionally, as Figure 2 shown, the display device 100 further includes a system control module 40;

[0056] The system control module 40 is configured to receive a mode selection request from a user and generate a corresponding mode selection signal according to the mode selection request, and the mode selection signal is used to indicate that the display panel 30 is configured in the first mode or the second mode;

[0057] The timing controller 20 is configured to download the first firmware resource or the second firmware resource from the data storage chip 10 based on the mode selection signal.

[0058] In this embodiment, the above system control module 40 (System Control Module) can be understood as the core of the interaction between the user and the display device 100. In the display device 100, the system control module 40 is responsible for processing the instructions input by the user and performing corresponding operations and controls on the display device 100 according to these instructions.

[0059] For example, the user inputs a mode selection request by clicking, swiping, long - pressing, etc. on the touch screen, or by inputting a voice command through the microphone. The system control module 40 can receive the user's mode selection signal.

[0060] The system control module 40 parses and converts the mode selection request through processes such as instruction parsing and processing, generates a corresponding mode selection signal, and distributes it to the corresponding timing controller 20 for processing. In this way, the timing controller 20 selects and downloads the first firmware resource or the second firmware resource from the data storage chip 10 according to the working mode to be configured for the display panel 30 indicated in the mode selection signal.

[0061] Please refer to Figure 3 , Figure 3 which is a schematic structural diagram of another display device 100 provided by an embodiment of the present application. According to some embodiments of the present application, optionally, as Figure 3 shown, the display device 100 further includes a selector 50. The selector 50 is electrically connected to the system control module 40 and the timing controller 20 respectively;

[0062] The selector 50 is configured to receive the mode selection signal transmitted by the system control module 40, and send a first selection signal or a second selection signal to the timing controller 20 according to the mode selection signal; the first selection signal corresponds to the first mode, and the second selection signal corresponds to the second mode;

[0063] The timing controller 20 is configured to download the first firmware resource from the data storage chip 10 when receiving the first selection signal; and download the second firmware resource from the data storage chip 10 when receiving the second selection signal.

[0064] In this embodiment, a selector 50 is provided between the system control module 40 and the timing controller 20. After the system control module 40 generates the corresponding mode selection signal, it distributes it to the selector 50. The selector 50 selects one of the preset first selection signal and second selection signal for output according to the received mode selection signal. In this way, the timing controller 20 downloads the first firmware resource or the second firmware resource from the data storage chip 10 through the first selection signal or the second selection signal output by the selector 50.

[0065] As an example, according to the mode selection signal indicating that the display panel 30 is configured in the first mode or the second mode, the mode selection signal can be 0 or 1 respectively, where 0 corresponds to the first mode and 1 corresponds to the second mode. The selector 50 is pre-set with a first selection signal corresponding to the first mode and a second selection signal corresponding to the second mode. The selector 50 can output the first selection signal or the second selection signal according to the received mode selection signal. The first selection signal and the second selection signal are, for example, analog signals such as level voltages, or can also be digital signals, etc., and are not strictly limited here.

[0066] After receiving the first selection signal or the second selection signal output by the selector 50, the timing controller 20 selects and downloads the first firmware resource or the second firmware resource from the data storage chip 10 by performing corresponding logical judgments.

[0067] More specifically, the storage addresses corresponding to the first firmware resource and the second firmware resource in the data storage chip 10 are pre-stored in the timing controller 20. The timing controller 20 can perform logical judgments according to the first selection signal or the second selection signal sent by the selector 50, and thus download the firmware resources using different storage addresses according to the logical judgment results, so as to accurately obtain the firmware resources corresponding to the mode required by the user.

[0068] Please refer to Figure 4 , Figure 4 which is a schematic structural diagram of another display device 100 provided by an embodiment of the present application. According to some embodiments of the present application, optionally, as Figure 4 shown, the data storage chip 10 includes a first flash memory chip 11 and a second flash memory chip 12, and the display device 100 further includes a switch module 60;

[0069] The control end of the switch module 60 is electrically connected to the system control module 40, the first end of the switch module 60 is electrically connected to the first flash memory chip 11, the second end of the switch module 60 is electrically connected to the second flash memory chip 12, and the third end of the switch module 60 is electrically connected to the timing controller 20;

[0070] The switch module 60 is configured to receive the mode selection signal sent by the system control module 40. When the mode selection signal is the first level voltage signal, the first end of the switch module 60 is connected to the third end of the switch module 60, so that the timing controller 20 downloads the first firmware resource from the first flash memory chip 11;

[0071] When the mode selection signal is the second level voltage signal, the second end of the switch module 60 is connected to the third end of the switch module 60, so that the timing controller 20 downloads the second firmware resource from the second flash memory chip 12.

[0072] In specific implementation, in the display device 100, the data storage chip 10 can be divided into two independent first flash memory chips 11 and second flash memory chips 12. The first firmware resources are stored in the first flash memory chip 11, and the second firmware resources are stored in the second flash memory chip 12. The first flash memory chip 11 and the second flash memory chip 12 can be of types such as NOR Flash chips, NAND Flash, eMMC (Embedded Multi Media Card), etc., and no strict limitation is made here.

[0073] A switch module 60 is provided between the timing controller 20, the first flash memory chip 11, and the second flash memory chip 12. In specific connection, the first end of the switch module 60 is electrically connected to the first flash memory chip 11, the second end of the switch module 60 is electrically connected to the second flash memory chip 12, and the third end of the switch module 60 is electrically connected to the timing controller 20.

[0074] The control end of the switch module 60 is electrically connected to the system control module 40. According to different level voltage signals corresponding to the mode selection signal output by the system control module 40, corresponding connections can be made between different terminals in the switch module 60.

[0075] Among them, the level voltage signal corresponding to the mode selection signal can be a first level voltage signal or a second level voltage signal. Exemplarily, the first level voltage signal is a high level, and the second level voltage signal is a low level. Or, the first level voltage signal is a low level, for example, and the second level voltage signal is a high level, for example. In this embodiment, the setting of the high and low level voltage signals corresponding to the mode selection signal can be determined according to the internal switch structure of the actual switch module 60, and no strict limitation is made here.

[0076] In this embodiment, when the control end of the switch module 60 receives the first level voltage signal, the first end and the third end of the switch module 60 are electrically connected, so that the timing controller 20 is connected to the first flash memory chip 11, and the timing controller 20 can directly download the first firmware resources from the first flash memory chip 11, so that the display panel 30 works in the first mode.

[0077] When the switch module 60 receives the second level voltage signal, the second end and the third end of the switch module 60 are electrically connected, so that the timing controller 20 is connected to the second flash memory chip 12, and the timing controller 20 can directly download the second firmware resources from the second flash memory chip 12, so that the display panel 30 works in the second mode.

[0078] In this embodiment, by setting the above-mentioned switch module 60, it is possible to directly determine from the hardware connection that the flash memory chip connected to the timing controller 20 is the first flash memory chip 11 or the second flash memory chip 12, thereby reducing the logical judgment steps inside the timing controller 20 and helping to quickly and simply implement the corresponding firmware resource download in the mode switching scenario.

[0079] Please refer to the following Figure 5 , Figure 5 which is a schematic structural diagram of another display device 100 provided by an embodiment of the present application. According to some embodiments of the present application, optionally, as Figure 5 shown, the switch module 60 includes a first switch unit 61 and a second switch unit 62;

[0080] The control end of the first switch unit 61 is electrically connected to the system control module 40, the first end of the first switch unit 61 is electrically connected to the first flash memory chip 11, and the second end of the first switch unit 61 is electrically connected to the timing controller 20;

[0081] The control end of the second switch unit 62 is electrically connected to the system control module 40, the first end of the second switch unit 62 is electrically connected to the second flash memory chip 12, and the second end of the second switch unit 62 is electrically connected to the timing controller 20;

[0082] In the case where the mode selection signal is a first-level voltage signal, the first switch unit 61 is turned on and the second switch unit 62 is turned off;

[0083] In the case where the mode selection signal is a second-level voltage signal, the first switch unit 61 is turned off and the second switch unit 62 is turned on.

[0084] In specific implementation, in order to fully implement the selection and connection control between the timing controller 20 and the first flash memory chip 11, and between the timing controller 20 and the second flash memory chip 12, the switch module 60 is specifically set to include a first switch unit 61 and a second switch unit 62.

[0085] The control end of the first switch unit 61 is electrically connected to the system control module 40, and is used to receive the mode selection signal sent by the system control module 40 and conduct or cut off in response to the mode selection signal.

[0086] When the first switching unit 61 is turned on, the first end and the second end of the first switching unit 61 are connected, thereby connecting the timing controller 20 to the first flash memory chip 11. The timing controller 20 can directly download the required first firmware resource from the connected first flash memory chip 11. When the first switching unit 61 is turned off, the connection between the timing controller 20 and the first flash memory chip 11 is disconnected, and the timing controller 20 cannot download the corresponding firmware resource from the first flash memory chip 11 through the first switching unit 61.

[0087] The control end of the second switching unit 62 is electrically connected to the system control module 40. The first end and the second end of the second switching unit 62 are connected, thereby connecting the timing controller 20 to the second flash memory chip 12. The timing controller 20 can directly download the required second firmware resource from the connected second flash memory chip 12. When the second switching unit 62 is turned off, the connection between the timing controller 20 and the second flash memory chip 12 is disconnected, and the timing controller 20 cannot download the corresponding firmware resource from the second flash memory chip 12 through the second switching unit 62.

[0088] In this embodiment, the first switching unit 61 and the second switching unit 62 are specifically arranged to reasonably implement the flash memory chip selection function of the foregoing switching module 60. Through the flexible conduction or cutoff of the second switching unit 62 and the second switching unit 62, it is possible to support connecting or disconnecting the timing controller 20 from the first flash memory chip 11 and the second flash memory chip 12 on the hardware, thereby facilitating the improvement of the firmware resource download efficiency of the timing controller and reducing the logical processing complexity.

[0089] Please refer to Figure 6 , Figure 6 which is a schematic structural diagram of another display device 100 provided by an embodiment of the present application. According to some embodiments of the present application, optionally, as Figure 6 shown, the first switching unit 61 includes a first transistor T1, and the second switching unit 62 includes a second transistor T2;

[0090] One of the first transistor T1 and the second transistor T2 is a P-channel transistor, and the other is an N-channel transistor.

[0091] In this embodiment, by setting the transistor channel types of the first transistor T1 and the second transistor T2 to be opposite, for example, the first transistor T1 is a P-channel transistor and the second transistor T2 is an N-channel transistor; or, as Figure 6 shown, the first transistor T1 is an N-channel transistor and the second transistor T2 is a P-channel transistor.

[0092] Thus, each time a mode is selected or switched, the system control module 40 only needs to provide a mode selection signal to enable the selective conduction of the first transistor T1 and the second transistor T2, thereby effectively implementing the selection and configuration of the first mode or the second mode.

[0093] Please refer to the following Figure 7 , Figure 7 which is a timing diagram of a screen display period provided by an embodiment of the present application. According to some embodiments of the present application, optionally, as Figure 7 shown, the screen display period of the display panel 30 in the first mode is the first screen display period, and there is at least one screen display period in the second mode that is the second screen display period.

[0094] Taking the period from the rising edge to the falling edge as the corresponding working stage as an example, the first screen display period includes a first display stage and a touch sensing stage. The first display stage corresponds to the display timing parameter in the first timing parameter, and the touch sensing stage corresponds to the touch timing parameter in the first timing parameter.

[0095] The second screen display period includes a second display stage and does not include a touch sensing stage. The second display stage corresponds to the display timing parameter in the second timing parameter.

[0096] In this embodiment, the first mode is, for example, a normal touch mode, and the second mode is, for example, a high refresh rate mode such as a game.

[0097] The above-mentioned first display stage and second display stage can be understood as the time periods for screen refreshing and displaying image content. In this stage, the display driver chip sends image data to the pixel array of the screen, thereby completing the display of the screen.

[0098] The above-mentioned touch sensing stage can be understood as the touch stage (Touch) where the touch chip detects and processes touch signals. In this stage, the touch chip identifies the touch position by detecting relevant voltage changes (such as voltage changes on the touch electrodes), and converts the touch signal into a digital signal to promptly identify and respond to the touch operation.

[0099] It should be added that in some embodiments, the touch sensing stage further includes a rescan stage (Rescan), in which the touch chip re-detects and calibrates the touch signal, thereby optimizing the accuracy and stability of touch operation detection.

[0100] In this embodiment, different firmware resources are loaded through the timing controller to achieve the switching of the timing parameters corresponding to the first mode and the second mode, so that the display panel works according to different timing parameters.

[0101] During specific operations, by setting the first screen display period in the first mode to include a first display phase and a touch sensing phase, and setting a second screen display period in the second mode, the second screen display period includes a second display phase but does not include a touch sensing phase.

[0102] In this way, by removing the touch-related timing parameters in the second screen display period in the second mode corresponding to the high refresh rate requirement, the second screen display period does not include the touch sensing phase, which is equivalent to removing the time period originally used for touch sensing in one frame in the second mode, thereby increasing the time period available for display per unit time.

[0103] In this way, by removing the touch sensing phase in the high refresh rate scenario in the second mode, the time of the display timing can be effectively increased, thereby fully improving the panel refresh rate of the display panel 30 in scenarios such as games.

[0104] For ease of understanding, please refer to the following example: In the first mode, the frame rate of the display panel 30 per unit time (1 s) is 60 Hz, and the first screen display period is 1 / 60 s. The first screen display period includes a first display phase and a touch sensing phase. In the second mode, since the touch sensing phase in one frame is removed, the frame rate of the display panel 30 per unit time in the second mode can be increased to, for example, 90 Hz, and the second screen display period is 1 / 90 s. In this way, more screen refreshes can be achieved in the second mode.

[0105] It should be understood that the first screen display period in this embodiment may also include a fingerprint recognition phase or other time periods in addition to the above-mentioned first display phase and touch sensing phase, and no strict limitation is made here. The second screen display period is similar and may also include a fingerprint recognition phase or other time periods.

[0106] It should also be added that, in combination with the actual application scenario of the second mode, the display device 100 may be a display device configured with, for example, a keyboard, voice, or joystick, such as a laptop computer, so as to ensure high refresh rate display of the panel screen in the game mode while fully meeting the user's interaction requirements with the display interface.

[0107] According to some embodiments of the present application, optionally, the second timing parameters do not include touch timing parameters;

[0108] Alternatively, the second timing parameters include touch timing parameters, and the touch timing parameters in the second timing parameters are used to instruct the display device 100 to skip the touch sensing phase in the corresponding screen display period.

[0109] In this embodiment, when the display panel 30 needs to operate in the second mode, the timing controller 20 outputs second timing parameters according to the second firmware resources. In order to fully ensure that the touch sensing stage is not included in the second frame display period in the second mode, by setting the touch timing parameters not to be included in the second timing parameters, the removal of the touch sensing stage can be directly achieved.

[0110] Alternatively, set the touch timing parameters in the second timing parameters. The touch timing parameters in the second timing parameters indicate that the display device 100 skips the touch sensing stage in the corresponding frame display period. In this way, by instructing to skip the touch sensing stage in the frame display period, the purpose of removing the touch sensing stage in the second mode can also be achieved.

[0111] Please refer to Figure 8 , Figure 8 which is a schematic structural diagram of another display device 100 provided by an embodiment of the present application. According to some embodiments of the present application, optionally, as Figure 8 shown, the display device 100 further includes a touch chip 70; the frame display period of the display panel 30 in the first mode is the first frame display period, and there is at least one frame display period in the second mode that is the second frame display period;

[0112] The timing controller 20 is configured to send a first touch control signal to the touch chip 70 based on first timing parameters when the display panel 30 is in the first mode; and send a second touch control signal to the touch chip 70 based on second timing parameters when the display panel 30 is in the second mode;

[0113] The touch chip 70 is configured to output a touch signal during the touch sensing stage within the first frame display period in response to the first touch control signal; and stop outputting the touch signal during the second frame display period in response to the second touch control signal.

[0114] In this embodiment, the touch operation of the display device 100 in different modes is described. The touch chip 70 (Touch Controller Chip) is electrically connected to the timing controller 20 and the display panel 30 respectively. The timing controller 20 can be responsible for coordinating the working timing of the touch chip 70 and adjusting the output and phase of the touch signal (tp signal).

[0115] The touch chip 70 can output a touch signal under the control of the timing controller 20, so as to sense the touch contact occurring on the screen through capacitance, resistance or other sensing technologies, and convert the touch signal into a corresponding electrical signal to promptly respond to the user's touch operation.

[0116] In specific implementation, when the display panel 30 needs to work in the first mode, the timing controller 20 sends a first touch control signal to the touch chip 70 according to the first timing parameter corresponding to the first mode. In response to the first touch control signal sent by the timing controller 20, the touch chip 70 outputs a touch signal during the touch sensing stage within the first frame display period in the first mode, so as to detect the touch contact occurring on the sensing screen.

[0117] When the display panel 30 needs to work in the second mode, the timing controller 20 sends a second touch control signal to the touch chip 70 according to the second timing parameter. In response to the second touch control signal sent by the timing controller 20, the touch chip 70 stops outputting the touch signal during the second frame display period in the second mode, so as to remove the touch sensing stage, so that the time period available for display per unit time in the second mode increases, and the refresh rate in the second mode is improved.

[0118] Please refer to Figure 9 , Figure 9 which is a schematic structural diagram of another display device 100 provided by an embodiment of the present application. According to some embodiments of the present application, optionally, as Figure 9 shown, the display device 100 further includes a display driving chip 80; the frame display period of the display panel 30 in the first mode is the first frame display period, and there is at least one frame display period in the second mode that is the second frame display period;

[0119] The timing controller 20 is configured to send a first display control signal to the display driving chip 80 based on the first timing parameter when the display panel is in the first mode; and send a second display control signal to the display driving chip 80 based on the second timing parameter when the display panel 30 is in the second mode;

[0120] The display driving chip 80 is configured to generate a first driving timing during the first display stage within the first frame display period in response to the first display control signal; and generate a second driving timing during the second display stage within the second frame display period in response to the second display control signal;

[0121] wherein, the ratio of the first display stage in the first frame display period is different from the ratio of the second display stage in the second frame display period.

[0122] In this embodiment, the display driving operation of the display device 100 in different modes is described. The display driving chip 80 (DDIC, Display Driver Integrated Circuit) is electrically connected to the timing controller 20 and the display panel 30 respectively. The display driving chip 80 can receive image data from the main board, convert it into a format suitable for the display panel, and generate the driving timing signals required by the display panel to complete screen refreshing and image content display.

[0123] During specific operation, when the display panel 30 needs to operate in the first mode, the timing controller 20 sends a first display control signal to the display driving chip 80 according to the first timing parameter. In response to the first display control signal sent by the timing controller 20, the display driving chip 80 outputs a first driving timing during the first display stage within the first frame display period in the first mode.

[0124] When the display panel 30 needs to operate in the second mode, the timing controller 20 sends a second display control signal to the display driving chip 80 according to the second timing parameter. In response to the second display control signal sent by the timing controller 20, the display driving chip 80 generates a second driving timing during the second display stage within the second frame display period in the second mode.

[0125] It should be noted that as Figure 10 shown, since the original touch sensing stage is removed during the second frame display period, the ratio of the first display stage within the first frame display period is different from the ratio of the second display stage within the second frame display period. Different ratios of the display stage within the frame display period can achieve a higher frequency of the display timing parameter in the second timing parameter than that in the first timing parameter.

[0126] According to some embodiments of the present application, optionally, please continue to refer to Figure 10 , the frame display period of the display panel 30 in the first mode is the first frame display period, and there is at least one frame display period in the second mode that is the second frame display period;

[0127] The first frame display period includes a first display stage, and the second frame display period includes a second display stage;

[0128] Among them, the ratio of the first display stage within the first frame display period is lower than the ratio of the second display stage within the second frame display period.

[0129] During specific implementation, by removing the touch sensing stage within the second frame display period, the ratio of the final first display stage within the first frame display period is lower than the ratio of the second display stage within the second frame display period.

[0130] As an example, Figure 10 in the first frame display period, the cycle ratio of the first display stage is 80%, and the cycle ratio of the touch sensing stage is, for example, 15%. The remaining time can be used for frame preparation work or others.

[0131] In the second frame display period, the cycle ratio of the second display stage is, for example, 95%. Due to the influence of the touch sensing stage, the 80% ratio of the first display stage in the first frame display period is lower than the 95% ratio of the second display stage in the second frame display period.

[0132] In this way, when the display panel 30 operates in the first mode and the second mode respectively, since the ratio of the second display stage in the second frame display period in the second mode is higher, a higher refresh rate can be achieved when the pixel charging is satisfied. In the same time, for example, within 1 second, the display panel 30 has a longer display time period, and the longer display time period is beneficial to achieving a higher refresh display, thereby helping to fully improve the user experience.

[0133] In a specific application example, in the first mode, the frame rate of the display panel 30 per unit time is 60Hz, and the first frame display period is 1 / 60s. The first frame display period includes a first display stage and a touch sensing stage.

[0134] In the second mode, the touch sensing stage is removed, and the cycle ratio of the second display stage is higher than that of the first display stage. More display data can be transmitted within the same unit time. Therefore, the frame rate of the display panel 30 per unit time in the second mode can be increased to, for example, 90Hz, and the second frame display period is 1 / 90s. Finally, more frame refreshes can be achieved in the second mode, realizing a higher refresh rate.

[0135] According to some embodiments of the present application, optionally, please refer to Figure 11 , the frame display period of the display panel 30 in the first mode is the first frame display period, and there is at least one frame display period in the second mode that is the second frame display period;

[0136] The time length D1 of the first frame display period is greater than the time length D2 of the second frame display period.

[0137] In this embodiment, since the touch sensing stage in the normal touch mode is removed, for example, when the time lengths of the first display stage and the second display stage are the same and both can satisfy the basic pixel charging display, the time length D2 of the second frame display period is shorter than the time length D1 of the first frame display period.

[0138] In this way, within the same unit time, since the time length D2 of the second screen display period is shorter, the display panel 30 can achieve more screen refreshes in the second mode, realizing a higher-frequency screen refresh display. Therefore, this embodiment can fully improve the high refresh rate of the display panel 30 in high-refresh scenarios such as games and videos, thereby improving the overall performance and market competitiveness of the product.

[0139] According to some embodiments of the present application, optionally, the timing controller 20 is configured to: reset in the case of power failure of the power supply of the display panel 30, and after completing the reset, download the first firmware resource from the data storage chip 10, or download the second firmware resource from the data storage chip 10.

[0140] In this embodiment, when the power supply of the display panel 30 is powered off, the display panel 30 and the timing controller 20 will be reset to the initial state, thereby ensuring that there are no residual abnormal states or error signals between the panel and the timing controller 20 after re-powering, ensuring the stability and reliability of subsequent mode switching operations.

[0141] When the timing controller 20 completes the reset, it downloads the corresponding firmware resource from the data storage chip 10, so that the display panel 30 operates according to the switching mode. By downloading the firmware and switching the mode after the timing controller 20 is reset, the stability of the firmware download can be guaranteed, and the working mode switching of the display panel 30 can be more correctly realized, thereby fully ensuring the stable operation and correct display of the display device 100.

[0142] It should be understood that the specific structure of the device provided in the drawings of the embodiments of the present application is only some examples and does not limit the present application. In addition, the above embodiments provided by the present application can be combined with each other without conflict.

[0143] Based on the display device provided in the foregoing embodiments, for the same inventive concept, the embodiments of the present application also provide a driving method for a display device, which is applied to the display device according to any one of the foregoing embodiments of the present application; the display panel in the display device is a display panel with in-plane touch function, and the display device includes:

[0144] A data storage chip, which stores a preset first firmware resource and a second firmware resource. The first firmware resource is the first timing parameter of the display panel in the first mode, and the second firmware resource is the second timing parameter of the display panel in the second mode;

[0145] A timing controller is used to download a first firmware resource from a data storage chip and output first timing parameters according to the first firmware resource when the display panel is configured in a first mode, so that the display panel displays in the first mode;

[0146] When the display panel is configured in a second mode, download a second firmware resource from the data storage chip and output second timing parameters according to the second firmware resource, so that the display panel displays in the second mode;

[0147] Among them, within one frame display period of the display panel, the first timing parameters include segmented display timing parameters and touch control timing parameters, the second timing parameters only include display timing parameters, and the frequency of the display timing parameters in the second timing parameters is higher than that of the display timing parameters in the first timing parameters.

[0148] The driving method of the display device provided by the embodiments of the present application has the beneficial effects of the display device provided by the embodiments of the present application. Specifically, reference can be made to the specific descriptions of the display device in the above embodiments, and details will not be repeated herein.

[0149] According to some embodiments of the present application, optionally, the frame display period of the display panel in the first mode is a first frame display period, and there is at least one frame display period in the second mode that is a second frame display period;

[0150] The first frame display period includes a first display stage and a touch sensing stage. The first display stage corresponds to the display timing parameters in the first timing parameters, and the touch sensing stage corresponds to the touch control timing parameters in the first timing parameters;

[0151] The second frame display period includes a second display stage and does not include a touch sensing stage. The second display stage corresponds to the display timing parameters in the second timing parameters.

[0152] In this embodiment, the first mode is, for example, a normal touch control mode, and the second mode is, for example, a high refresh rate mode such as a game. In this embodiment, by loading different firmware resources through the timing controller, the switching of the timing parameters corresponding to the first mode and the second mode is realized, so that the display panel works according to different timing parameters.

[0153] During specific operation, by setting the first frame display period in the first mode to include a first display stage and a touch sensing stage, and setting that there is a second frame display period in the second mode, and the second frame display period includes a second display stage but does not include a touch sensing stage.

[0154] In this way, by removing the touch-related timing parameters during the second frame display period in the second mode corresponding to the high refresh rate requirement, the touch sensing stage is not included in the second frame display period, which is equivalent to removing the time period originally used for touch sensing in one frame in the second mode, so that the time period available for display per unit time is increased.

[0155] In this way, by removing the touch sensing stage in the high refresh rate scenario in the second mode, the time of the display timing can be effectively increased, which helps to fully improve the panel refresh rate of the display panel in scenarios such as games.

[0156] According to some embodiments of the present application, optionally, the second timing parameters do not include touch timing parameters;

[0157] Or, the second timing parameters include touch timing parameters, and the touch timing parameters in the second timing parameters are used to instruct the display device to skip the touch sensing stage during the corresponding frame display period.

[0158] In this embodiment, when the display panel needs to operate in the second mode, the timing controller outputs the second timing parameters according to the second firmware resources. In order to fully ensure that the second frame display period in the second mode does not include the touch sensing stage, by setting that the second timing parameters do not include touch timing parameters, the removal of the touch sensing stage can be directly realized.

[0159] Or, set the touch timing parameters in the second timing parameters, and the touch timing parameters in the second timing parameters instruct the display device to skip the touch sensing stage during the corresponding frame display period. In this way, by instructing to skip the touch sensing stage during the frame display period, the purpose of removing the touch sensing stage in the second mode can also be achieved.

[0160] According to some embodiments of the present application, optionally, the frame display period of the display panel in the first mode is the first frame display period, and there is at least one frame display period in the second mode that is the second frame display period;

[0161] The first frame display period includes a first display stage, and the second frame display period includes a second display stage;

[0162] Wherein, the proportion of the first display stage in the first frame display period is lower than the proportion of the second display stage in the second frame display period.

[0163] In specific implementation, by removing the touch sensing stage in the second frame display period, the proportion of the final first display stage in the first frame display period is lower than the proportion of the second display stage in the second frame display period.

[0164] Thus, when the display panel operates in the first mode and the second mode respectively, since the proportion of the second display phase in the second frame display period in the second mode is higher, within the same time, for example, within 1 second, the display panel has a longer display time period, and the longer display time period is beneficial to achieving a higher refresh display, thereby helping to fully improve the user experience.

[0165] According to some embodiments of the present application, optionally, the frame display period of the display panel in the first mode is the first frame display period, and there is at least one frame display period in the second mode that is the second frame display period;

[0166] The time length of the first frame display period is greater than the time length of the second frame display period.

[0167] In this embodiment, since the touch sensing phase in the normal touch mode is removed, for example, when the time lengths of the first display phase and the second display phase are the same, the time length of the second frame display period will be shorter compared to the second frame display period.

[0168] Thus, within the same time, the display panel can achieve a higher frequency of frame refresh display in the second mode. Therefore, this embodiment can fully improve the high refresh rate of the display panel 30 in high refresh scenarios such as games and videos, thereby improving the overall performance and market competitiveness of the product.
