[0002] With the rapid development of display technology, display panels are being used more and more widely in various fields. During this development, consumers' demands for user experience and integrated functionality in display panels are also increasing, prompting product development towards low power consumption, high refresh rates, and high image quality. Simultaneously, the functions integrated into display panels are becoming increasingly diverse. However, in current display panel operation, there is a problem of relatively low screen refresh rates in scenarios requiring high refresh rates, such as gaming mode or movie playback. Summary of the Invention

[0003] This application provides a display device and a driving method for the display device, which can quickly and effectively realize the mode switching of the display panel and help improve the refresh rate of the display panel in high refresh rate demand scenarios.

[0004] In a first aspect, embodiments of this application provide a display device, wherein the display panel in the display device is a display panel with in-plane touch functionality, and the display device includes:

[0005] The data storage chip stores a preset first firmware resource and a second firmware resource. The first firmware resource includes a first timing parameter of the display panel in a first mode, and the second firmware resource includes a second timing parameter of the display panel in a second mode.

[0006] A timing controller is used to download a first firmware resource from a data storage chip and output a first timing parameter according to the first firmware resource when the display panel is configured in a first mode.

[0007] When the display panel is configured in the second mode, the second firmware resource is downloaded from the data storage chip, and the second timing parameters are output according to the second firmware resource;

[0008] Within one display cycle of the display panel, the first timing parameter includes display timing parameters and touch timing parameters, and the second timing parameter includes display timing parameters. The frequency of the display timing parameters in the second timing parameter is higher than the frequency of the display timing parameters in the first timing parameter.

[0009] Based on the same inventive concept, in a second aspect, embodiments of this application provide a driving method for a display device, applied to a display device as described in the foregoing embodiments of this application; the display panel in the display device is a display panel with in-plane touch functionality, and the display device includes:

[0010] The data storage chip stores a 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.

[0011] A timing controller is used to download first firmware resources from a data storage chip and output first timing parameters according to the first firmware resources when the display panel is configured in a first mode, so that the display panel displays in the first mode.

[0012] When the display panel is configured in the second mode, the second firmware resource is downloaded from the data storage chip, and the second timing parameters are output according to the second firmware resource so that the display panel displays in the second mode;

[0013] Within one display cycle of the display panel, the first timing parameter includes segmented display timing parameters and touch timing parameters, while the second timing parameter only includes display timing parameters. The frequency of the display timing parameters in the second timing parameter is higher than the frequency of the display timing parameters in the first timing parameter.

[0014] Compared to related technologies, the display device and its driving method in this application embodiment load firmware resources corresponding to different modes from the data storage chip through a timing controller to quickly and efficiently switch timing parameters between normal display scenarios and high refresh rate display scenarios, thereby effectively realizing mode switching between the first mode and the second mode of the display panel. Furthermore, in terms of timing parameter settings, this application embodiment ensures that the display panel with in-plane touch functionality can perform display and normal touch sensing in the normal first mode by setting the first timing parameters to include display timing parameters and touch timing parameters. By setting the second timing parameters to include display timing parameters, and ensuring that 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, the refresh rate of the display panel in high refresh rate demand scenarios can be effectively improved, which helps to improve product quality and market competitiveness.

[0027] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the 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 this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

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

[0029] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0030] It should be noted that the transistors in the embodiments of this application can be either N-type or P-type transistors. For N-type transistors, the on-state level is high and the off-state level is low. That is, when the gate of an N-type transistor is high, its first and second terminals are connected; when the gate of an N-type transistor is low, its first and second terminals are off. For P-type transistors, the on-state level is low and the off-state level is high. That is, when the control terminal of a P-type transistor is low, its first and second terminals are connected; when the control terminal of a P-type transistor is high, its first and second terminals are off. In specific implementations, the gate of each transistor is used as its control terminal. Furthermore, depending on the signal and type of the gate of each transistor, its first terminal can be used as the source and its second terminal as the drain, or vice versa. No distinction is made here. Additionally, the on-state and off-state levels in the embodiments of this invention are general terms. The on-state level refers to any level that enables the transistor to conduct, and the off-state level refers to any level that enables the transistor to turn off / become off.

[0031] In the embodiments of this application, the term "electrical connection" can refer to a direct electrical connection between two components, or it can refer to an electrical connection between two components via one or more other components.

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

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

[0034] Before describing the technical solutions provided in the embodiments of this application, in order to facilitate understanding of the embodiments of this application, this application first specifically explains the problems existing in the related technologies:

[0035] As mentioned earlier, with the continuous development of display technology, the functions integrated into display panels are becoming increasingly diverse. Taking Incell Touch Display (ITD) technology as an example, this technology integrates touch sensor functionality into the liquid crystal display (LCD). Specifically, this technology reuses a common electrode as a touch electrode. During the display phase, a common voltage signal is input to the common electrode, forming an electric field between the common electrode and the pixel electrode, thereby controlling the deflection of the liquid crystal and achieving image display. During the touch phase: the common electrode is reused as a touch electrode. When a user touches the screen, it changes the electric field distribution on the touch electrode, causing a voltage change. By detecting these voltage changes through a touch chip, the touch location can be identified. This integration tightly combines touch and display functions, making the entire display thinner and lighter, reducing screen thickness and weight. Based on these advantages, Incell Touch Display technology is widely used in modern electronic devices, including smartphones, tablets, and laptops.

[0036] However, the inventors of this application have discovered that, at present, for in-cell touch display panels employing the aforementioned Incell TouchDisplay technology, the refresh rate of such panels is difficult to effectively improve in high-refresh-rate scenarios such as game mode or movie playback, resulting in a low screen refresh rate. This leads to a poor gaming experience for users, such as in game mode, reduces the quality of the display panel product, and makes it difficult to meet market demands for high refresh rate performance.

[0037] In view of the above, the present application provides a display device and a driving method for the display device, which can solve the technical problem in the related art that the refresh rate of a display panel with in-plane touch function is difficult to effectively improve.

[0038] The display device 100 provided in the embodiments of this application will be described below. Please refer to [link to relevant documentation] first. Figure 1 , Figure 1 This is a schematic diagram of the structure of a display device 100 provided in an embodiment of this application. It is understood that the display device 100 provided in this embodiment of the application can be other display devices 100 with display functions, such as wearable products, computers, televisions, vehicle display devices 100, etc., and this application does not impose specific limitations on them.

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

[0040] The data storage chip 10 stores a preset first firmware resource and a second firmware resource. The first firmware resource includes a first timing parameter of the display panel 30 in a first mode, and the second firmware resource includes a second timing parameter of the display panel 30 in a second mode.

[0041] Timing controller 20 is used to download first firmware resources from data storage chip 10 and output 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, the second firmware resource is downloaded from the data storage chip 10, and the second timing parameters are output according to the second firmware resource;

[0043] Within one display cycle of the display panel 30, the first timing parameter includes display timing parameters and touch timing parameters, and the second timing parameter includes display timing parameters. The frequency of the display timing parameters in the second timing parameter is higher than the frequency of the display timing parameters in the first timing parameter.

[0044] In this application, the display device 100 includes, for example, smartphones, tablets, and laptops. The display panel 30 in the display device 100 that has in-plane touch functionality can be understood as a display panel 30 using In-cell Touch Display technology. The display panel 30 is, for example, an LCD panel, but is not strictly limited to this.

[0045] The first mode described above specifically corresponds to low refresh rate display scenarios, such as when the display panel 30 needs to display static images or text information. In this scenario, the display panel 30 displays according to the first mode, which helps to reduce power consumption through a low refresh rate.

[0046] The aforementioned second mode specifically corresponds to high refresh rate display scenarios, such as display scenarios where the display panel 30 needs to display dynamic content, such as e-sports games, live streaming, 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 screen tearing and blurring, thereby providing a smoother visual experience and fully meeting user experience needs.

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

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

[0049] The timing controller 20 (TCON) is responsible for managing the timing control of pixel data, ensuring that the displayed content is presented correctly. Before the timing controller 20 operates, the data storage chip 10 needs to provide the corresponding firmware resources to the timing controller 20 so that the timing controller 20 can output the corresponding control signals and data signals to the screen driver according to the correct required timing. When users have different display requirements, such as adjusting the resolution, refresh rate, or color mode, the timing controller 20 will adjust its output signals and control logic accordingly to make the display effect meet expectations.

[0050] The data storage chip 10 and the timing controller 20 can communicate with each other, enabling the timing controller 20 to read and download firmware resources from 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 via the I2C (Inter-Integrated Circuit) bus. The firmware resources contain the program resources required for the initialization of the timing controller 20, such as timing parameters and calibration data.

[0051] In this application, 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 aforementioned first and second timing parameters can be used to configure the internal registers and operating mode of the timing controller 20, ensuring that the timing controller 20 can correctly generate control signals and data signals.

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

[0054] Furthermore, in this embodiment, within one display cycle of the display panel 30, the first timing parameters corresponding to the first mode include display timing parameters and touch timing parameters. This ensures that the display panel 30 with in-plane touch functionality can display and respond to touch 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 the frequency of the display timing parameters in the first timing parameters. This ensures high refresh rate display of the display panel 30, thereby fully meeting the high refresh rate display needs of users in scenarios such as games, and thus enhancing the product competitiveness of the display device.

[0055] Please see below. Figure 2 , Figure 2 This is a schematic diagram of another display device 100 provided in an embodiment of this application. Optionally, according to some embodiments of this application, such as... Figure 2 As shown, the display device 100 also includes a system control module 40;

[0056] The system control module 40 is used to receive the user's mode selection request and generate a corresponding mode selection signal according to the mode selection request. The mode selection signal is used to indicate whether the display panel 30 is configured as the first mode or the second mode.

[0057] The timing controller 20 is used to download either 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 system control module 40 can be understood as the core of the interaction between the user and the display device 100. Within the display device 100, the system control module 40 is responsible for processing user-input commands and performing corresponding operations and controls on the display device 100 based on these commands.

[0059] For example, when a user taps, swipes, or long-presses on the touchscreen, or when a user inputs a mode selection request via voice commands 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 instruction parsing and processing, generates a corresponding mode selection signal, and distributes it to the corresponding timing controller 20 for processing. Thus, the timing controller 20 selects to download either the first firmware resource or the second firmware resource from the data storage chip 10 according to the operating mode to be configured on the display panel 30 indicated in the mode selection signal.

[0061] Please see below. Figure 3 , Figure 3 This is a schematic diagram of the structure of another display device 100 provided in an embodiment of this application. Optionally, according to some embodiments of this application, such as... Figure 3 As shown, the display device 100 also includes a selector 50, which is electrically connected to the system control module 40 and the timing controller 20 respectively.

[0062] Selector 50 is used to receive the mode selection signal transmitted by system control module 40, and send a first selection signal or a second selection signal to 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 a first firmware resource from the data storage chip 10 when a first selection signal is received, and to download a second firmware resource from the data storage chip 10 when a second selection signal is received.

[0064] In this embodiment, a selector 50 is provided between the system control module 40 and the timing controller 20. After generating the corresponding mode selection signal, the system control module 40 distributes it to the selector 50. The selector 50 selects one of a preset first selection signal and a second selection signal for output based on 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, the display panel 30 is configured to either a first mode or a second mode according to the mode selection signal. The mode selection signal can be 0 or 1, with 0 corresponding to the first mode and 1 corresponding 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 can be analog signals such as voltage levels, or they can also be digital signals, etc., without strict limitation.

[0066] After receiving the first selection signal or the second selection signal output by the selector 50, the timing controller 20 performs corresponding logical judgments to select the first firmware resource or the second firmware resource to download from the data storage chip 10.

[0067] More specifically, the timing controller 20 pre-stores the storage addresses corresponding to the first firmware resource and the second firmware resource in the data storage chip 10. The timing controller 20 can perform logical judgments based on the first selection signal or the second selection signal sent by the selector 50, and then use different storage addresses to download the firmware resource according to the logical judgment results, thereby accurately obtaining the firmware resource corresponding to the mode required by the user.

[0068] Please see below. Figure 4 , Figure 4 This is a schematic diagram of the structure of another display device 100 provided in an embodiment of this application. Optionally, according to some embodiments of this application, such as... Figure 4 As 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 also includes a switch module 60;

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

[0070] The switch module 60 is configured to receive a mode selection signal sent by the system control module 40. When the mode selection signal is a first level voltage signal, the first terminal of the switch module 60 is connected to the third terminal 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 terminal of the switch module 60 is connected to the third terminal 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 a specific implementation, within 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 flash memory chip 11 stores first firmware resources, and the second flash memory chip 12 stores second firmware resources. The first flash memory chip 11 and the second flash memory chip 12 can be of various types, such as NOR Flash chips, NAND Flash, or eMMC (Embedded Multi Media Card), and are not strictly limited here.

[0073] A switch module 60 is provided between the timing controller 20 and the first flash memory chip 11 and the second flash memory chip 12. Specifically, 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 terminal of the switch module 60 is electrically connected to the system control module 40. Depending on the different level voltage signals corresponding to the mode selection signals output by the system control module 40, corresponding connections can be made between different terminals in the switch module 60.

[0075] The voltage level signal corresponding to the mode selection signal can be either a first voltage level signal or a second voltage level signal. For example, the first voltage level signal is high, and the second voltage level signal is low. Alternatively, the first voltage level signal can be low, and the second voltage level signal can be high. In this embodiment, the setting of the high and low voltage levels corresponding to the mode selection signal can be determined according to the internal switching structure of the actual switching module 60, and is not strictly limited here.

[0076] In this embodiment, when the control terminal of the switch module 60 receives the first level voltage signal, the first terminal and the third terminal of the switch module 60 are electrically connected, thereby connecting the timing controller 20 with the first flash memory chip 11. The timing controller 20 can directly download the first firmware resource from the first flash memory chip 11, thereby enabling the display panel 30 to work according to the first mode.

[0077] When the switch module 60 receives the second level voltage signal, the second terminal and the third terminal of the switch module 60 are electrically connected, thereby connecting the timing controller 20 to the second flash memory chip 12. The timing controller 20 can directly download the second firmware resources from the second flash memory chip 12, thereby enabling the display panel 30 to work in the second mode.

[0078] In this embodiment, by setting the switch module 60, it is possible to directly determine from the hardware connection whether 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 achieve fast and simple download of the corresponding firmware resources in the mode switching scenario.

[0079] Please see below. Figure 5 , Figure 5 This is a schematic diagram of the structure of another display device 100 provided in an embodiment of this application. Optionally, according to some embodiments of this application, such as... Figure 5 As shown, the switch module 60 includes a first switch unit 61 and a second switch unit 62;

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

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

[0082] When the mode selection signal is a first level voltage signal, the first switching unit 61 is turned on and the second switching unit 62 is turned off.

[0083] When the mode selection signal is the 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 realize the selective 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 configured to include a first switch unit 61 and a second switch unit 62.

[0085] The control terminal of the first switching 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 to turn on or off in response to the mode selection signal.

[0086] When the first switch unit 61 is turned on, its first and second terminals are connected, thereby connecting the timing controller 20 to the first flash memory chip 11. The timing controller 20 can then directly download the required first firmware resources from the connected first flash memory chip 11. When the first switch unit 61 is turned off, the connection between the timing controller 20 and the first flash memory chip 11 is broken, and the timing controller 20 cannot download the corresponding firmware resources from the first flash memory chip 11 through the first switch unit 61.

[0087] The control terminal of the second switching unit 62 is electrically connected to the system control module 40. The first and second terminals 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 resources 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 broken, and the timing controller 20 cannot download the corresponding firmware resources from the second flash memory chip 12 through the second switching unit 62.

[0088] In this embodiment, a first switch unit 61 and a second switch unit 62 are specifically configured to reasonably realize the flash memory chip selection function of the aforementioned switch module 60. By flexibly turning on or off the second switch unit 62, it is possible to support the hardware connection or disconnection between the timing controller 20 and the first flash memory chip 11 and the second flash memory chip 12, thereby facilitating the improvement of firmware resource download efficiency of the timing controller and reducing the complexity of logic processing.

[0089] Please see below. Figure 6 , Figure 6 This is a schematic diagram of the structure of another display device 100 provided in an embodiment of this application. Optionally, according to some embodiments of this application, such as... Figure 6 As 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, the transistor channel types of the first transistor T1 and the second transistor T2 are set 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 As 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 selection or switch is performed, the system control module 40 only needs to provide a mode selection signal to enable selective conduction of the first transistor T1 and the second transistor T2, thereby effectively realizing the selection and configuration of the first mode or the second mode.

[0093] Please see below. Figure 7 , Figure 7 This is a timing diagram illustrating a screen display cycle provided in an embodiment of this application. Optionally, according to some embodiments of this application, such as... Figure 7 As shown, the display panel 30 has a first display cycle in the first mode and at least one display cycle in the second mode that is a second display cycle.

[0094] Taking the period from the rising edge to the falling edge as the corresponding working stage as an example, the first screen display cycle 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 timing parameters in the first timing parameters.

[0095] The second screen display cycle includes the second display phase but does not include the touch sensing phase. The second display phase corresponds to the display timing parameters in the second timing parameters.

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

[0097] The first and second display stages mentioned above can be understood as the time periods during which the screen refreshes and displays image content. During this stage, the display driver chip sends image data to the pixel array of the screen, thereby completing the display of the image.

[0098] The aforementioned touch sensing stage can be understood as the touch stage 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 recognize and respond to touch operations.

[0099] It should be added that, in some embodiments, the touch sensing stage also includes a rescan stage, 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 by a timing controller to switch the timing parameters corresponding to the first mode and the second mode, so that the display panel works according to different timing parameters.

[0101] In practical operation, the first screen display cycle in the first mode is set to include a first display stage and a touch sensing stage, and a second screen display cycle is set in the second mode, which includes a second display stage but does not include a touch sensing stage.

[0102] Thus, by removing touch-related timing parameters from the second screen display cycle in the second mode corresponding to high refresh rate requirements, the touch sensing stage is not included in the second screen display cycle. This 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 stage in the high refresh rate scenario in the second mode, the display timing time can be effectively increased, thereby significantly 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 is 60Hz per unit time (1 second), and the first frame display cycle is 1 / 60s, which 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 can be increased to, for example, 90Hz per unit time, and the second frame display cycle is 1 / 90s, thus enabling more screen refreshes in the second mode.

[0105] It should be understood that the first screen display cycle in this embodiment may include a fingerprint recognition phase or other time periods in addition to the first display phase and touch sensing phase described above, and is not strictly limited here. The second screen display cycle 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 can be a display device equipped with a keyboard, voice or gamepad, such as a laptop computer, so as to ensure that the panel screen can be displayed at a high refresh rate in game mode while fully meeting the user's interaction needs with the display interface.

[0107] Optionally, according to some embodiments of this application, the second timing parameters do not include touch timing parameters;

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

[0109] In this embodiment, when the display panel 30 needs to operate in the second mode, the timing controller 20 outputs the second timing parameters according to the second firmware resources. In order to ensure that the second screen display cycle in the second mode does not include the touch sensing stage, the touch sensing stage can be directly removed by setting the second timing parameters to exclude the touch timing parameters.

[0110] Alternatively, a touch timing parameter can be set in the second timing parameters to instruct the display device 100 to skip the touch sensing phase in the corresponding screen display cycle. Thus, by instructing the skipping of the touch sensing phase in the screen display cycle, the purpose of removing the touch sensing phase in the second mode can also be achieved.

[0111] Please see below. Figure 8 , Figure 8 This is a schematic diagram of the structure of another display device 100 provided in an embodiment of this application. Optionally, according to some embodiments of this application, such as... Figure 8 As shown, the display device 100 also includes a touch chip 70; the display panel 30 has a first display cycle in the first mode and at least one display cycle in the second mode that is a second display cycle.

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

[0113] The touch chip 70 is used to respond to a first touch control signal, output a touch signal during the touch sensing phase within a first screen display cycle, and stop outputting the touch signal during a second screen display cycle in response to a second touch control signal.

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

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

[0116] In specific implementation, when the display panel 30 needs to operate in the first mode, the timing controller 20 sends a first touch control signal to the touch chip 70 according to the first timing parameters 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 phase of the first screen display cycle in the first mode, thereby detecting touch contact occurring on the sensing screen.

[0117] When the display panel 30 needs to operate in the second mode, the timing controller 20 sends a second touch control signal to the touch chip 70 according to the second timing parameters. In response to the second touch control signal sent by the timing controller 20, the touch chip 70 stops outputting touch signals during the second screen display cycle in the second mode, thereby removing the touch sensing phase. This increases the time period available for display per unit time in the second mode, resulting in an improved refresh rate.

[0118] Please see below. Figure 9 , Figure 9 This is a schematic diagram of the structure of another display device 100 provided in an embodiment of this application. Optionally, according to some embodiments of this application, such as... Figure 9 As shown, the display device 100 also includes a display driver chip 80; the display panel 30 has a first display cycle in the first mode and at least one display cycle in the second mode that is a second display cycle.

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

[0120] The display driver chip 80 is configured to generate a first driving timing sequence in response to a first display control signal during a first display phase within a first screen display cycle; and to generate a second driving timing sequence in response to a second display control signal during a second display phase within a second screen display cycle.

[0121] The proportion of the first display phase within the first screen display cycle is different from the proportion of the second display phase within the second screen display cycle.

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

[0123] In 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 driver chip 80 according to the first timing parameters. In response to the first display control signal sent by the timing controller 20, the display driver chip 80 outputs the first driving timing within the first display phase of the first screen display cycle 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 driver chip 80 according to the second timing parameters. In response to the second display control signal sent by the timing controller 20, the display driver chip 80 generates a second driving timing sequence in the second display phase within the second screen display cycle in the second mode.

[0125] It should be noted that, as Figure 10 As shown, because the original touch-sensing phase is removed in the second display cycle, the proportion of the first display phase in the first display cycle differs from the proportion of the second display phase in the second display cycle. This difference in the proportion of the display phases within the display cycle allows the frequency of the display timing parameters in the second timing parameters to be higher than the frequency of the display timing parameters in the first timing parameters.

[0126] According to some embodiments of this application, optionally, please continue to refer to Figure 10 The display panel 30 has a screen display cycle of the first screen display cycle in the first mode and at least one screen display cycle of the second screen display cycle in the second mode.

[0127] The first screen display cycle includes a first display phase, and the second screen display cycle includes a second display phase;

[0128] The proportion of the first display phase within the first screen display cycle is lower than the proportion of the second display phase within the second screen display cycle.

[0129] In practice, by removing the touch-sensing phase during the second screen display cycle, the proportion of the first display phase during the first screen display cycle is lower than the proportion of the second display phase during the second screen display cycle.

[0130] As an example, Figure 10 In the first screen display cycle, the first display phase accounts for 80% of the cycle, the touch sensing phase accounts for, for example, 15% of the cycle, and the remaining time can be used for screen preparation or other tasks.

[0131] Within the second display cycle, the second display phase accounts for, for example, 95% of the cycle. Due to the influence of the touch sensing phase, the first display phase accounts for 80% of the first display cycle, which is lower than the second display phase accounting for 95% of the second display cycle.

[0132] Thus, when the display panel 30 operates in the first mode and the second mode respectively, the second display phase within the second screen display cycle in the second mode accounts for a higher proportion, enabling a higher refresh rate while still satisfying pixel charging requirements. Within the same time frame, for example, within one second, the display panel 30 has a longer display period, and this longer display period facilitates higher refresh rates, thereby significantly improving the user experience.

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

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

[0135] According to some embodiments of this application, optionally, please refer to [the following]. Figure 11 The display panel 30 has a screen display cycle of the first screen display cycle in the first mode and at least one screen display cycle of the second screen display cycle in the second mode.

[0136] The duration of the first screen display cycle, D1, is greater than the duration of the second screen display cycle, D2.

[0137] In this embodiment, since the touch sensing phase in the normal touch mode is removed, for example, if the time periods of the first display phase and the second display phase are the same and both can satisfy the basic pixel charging display, the time length D2 of the second screen display cycle will be shorter than the time length D1 of the first screen display cycle.

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

[0139] According to some embodiments of this application, optionally, the timing controller 20 is used to: reset the display panel 30 when the power supply to the display panel 30 is de-energized, and download a first firmware resource from the data storage chip 10, or download a second firmware resource from the data storage chip 10 after the reset is completed.

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

[0141] Upon completion of the reset, the timing controller 20 downloads the corresponding firmware resources from the data storage chip 10, thereby enabling the display panel 30 to operate according to the switching mode. By resetting the timing controller 20 and then downloading the firmware and switching modes, the stability of the firmware download is ensured, and the switching of the display panel 30's operating mode is more accurately realized, thus fully guaranteeing the stable operation and correct display of the display device 100.

[0142] It should be understood that the specific structures of the devices provided in the accompanying drawings of the embodiments of this application are merely examples and are not intended to limit this application. Furthermore, the above embodiments provided in this application can be combined with each other unless there is contradiction.

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

[0144] The data storage chip stores a 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 first firmware resources from a data storage chip and output first timing parameters according to the first firmware resources 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 the second mode, the second firmware resource is downloaded from the data storage chip, and the second timing parameters are output according to the second firmware resource so that the display panel displays in the second mode;

[0147] Within one display cycle of the display panel, the first timing parameter includes segmented display timing parameters and touch timing parameters, while the second timing parameter only includes display timing parameters. The frequency of the display timing parameters in the second timing parameter is higher than the frequency of the display timing parameters in the first timing parameter.

[0148] The driving method for the display device provided in this application has the beneficial effects of the display device provided in this application. For details, please refer to the specific description of the display device in the above embodiments. This embodiment will not repeat the description here.

[0149] According to some embodiments of this application, optionally, the display panel has a first display cycle in the first mode and at least one display cycle in the second mode is the second display cycle;

[0150] The first screen display cycle 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 timing parameters in the first timing parameters.

[0151] The second screen display cycle includes the second display phase but does not include the touch sensing phase. The second display phase corresponds to the display timing parameters in the second timing parameters.

[0152] 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 mode. In this embodiment, different firmware resources are loaded by a timing controller to switch the timing parameters corresponding to the first mode and the second mode, so that the display panel operates according to different timing parameters.

[0153] In practical operation, the first screen display cycle in the first mode is set to include a first display stage and a touch sensing stage, and a second screen display cycle is set in the second mode, which includes a second display stage but does not include a touch sensing stage.

[0154] Thus, by removing touch-related timing parameters from the second screen display cycle in the second mode corresponding to high refresh rate requirements, the touch sensing stage is not included in the second screen display cycle. This 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.

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

[0156] Optionally, according to some embodiments of this application, the second timing parameters do not include touch timing parameters;

[0157] Alternatively, the second timing parameter may include a touch timing parameter, which is used to instruct the display device to skip the touch sensing phase in the corresponding screen display cycle.

[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 ensure that the second screen display cycle in the second mode does not include the touch sensing phase, the touch sensing phase can be directly removed by setting the second timing parameters to exclude the touch timing parameters.

[0159] Alternatively, a touch timing parameter can be set in the second timing parameters to instruct the display device to skip the touch sensing phase during the corresponding screen display cycle. In this way, by instructing the skipping of the touch sensing phase during the screen display cycle, the purpose of removing the touch sensing phase in the second mode can also be achieved.

[0160] According to some embodiments of this application, optionally, the display panel has a first display cycle in the first mode and at least one display cycle in the second mode is the second display cycle;

[0161] The first screen display cycle includes a first display phase, and the second screen display cycle includes a second display phase;

[0162] The proportion of the first display phase within the first screen display cycle is lower than the proportion of the second display phase within the second screen display cycle.

[0163] In practice, by removing the touch-sensing phase during the second screen display cycle, the proportion of the first display phase during the first screen display cycle is lower than the proportion of the second display phase during the second screen display cycle.

[0164] Thus, when the display panel operates in the first mode and the second mode respectively, since the second display phase accounts for a higher proportion in the second screen display cycle in the second mode, the display panel has a longer display time in the same amount of time, such as 1 second. The longer display time is conducive to achieving higher refresh rates, thereby helping to fully improve the user experience.

[0165] According to some embodiments of this application, optionally, the display panel has a first display cycle in the first mode and at least one display cycle in the second mode is the second display cycle;

[0166] The duration of the first screen display cycle is longer than the duration of the second screen display cycle.

[0167] In this embodiment, since the touch sensing phase in normal touch mode is removed, the duration of the second screen display cycle will be shorter than that of the second screen display cycle, for example, when the time periods of the first display phase and the second display phase are the same.

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