Description

Technical Field

[0001] This application belongs to the field of display technology, and in particular relates to a field sequence display control method, device and display control system. Background Technology

[0002] In-vehicle display systems are widely used in dashboards, central control screens, and head-up displays. Field-sequential display technology, due to its lightweight structure and high display efficiency, has been applied to some in-vehicle display solutions. Current field-sequential displays typically output color subfields according to a preset subfield sequence to form the corresponding color image.

[0003] However, in real-world vehicle environments, external lighting conditions change frequently. For example, direct sunlight during the day, low light at night, and situations such as vehicles entering or exiting tunnels or being shaded by trees can all affect the display viewing experience. Furthermore, the driving state, illumination state, and timing state of the display device may change under different operating conditions, making the overall operation more complex. Current technologies still need improvement in terms of display stability, viewing comfort, and overall operational consistency in complex vehicle environments. Summary of the Invention

[0004] In view of this, embodiments of this application provide a field sequence display control method, apparatus and display control system to achieve adaptive adjustment of display devices under extreme lighting changes, and optimize display quality and power efficiency.

[0005] A first aspect of this application provides a field sequence display control method, the method comprising: Acquire the ambient light intensity of the vehicle's external environment; Based on the ambient light intensity, determine the target field sequence driving timing of the current frame of the display device; Based on the target field sequence driving timing, determine the target touch control parameters that match the current frame field sequence display; According to the target field sequence driving timing, the corresponding sub-field driving signal is output. The sub-field driving signal is used to control the display device to perform field sequence display according to the arrangement order and timing relationship of multiple sub-fields. Touch control is performed according to the target touch control parameters so that the touch control matches the current frame field sequence display.

[0006] In this embodiment, by acquiring the ambient light intensity of the vehicle's external environment, the field sequence display control is established based on the perception of changes in the ambient light of the current scene, thereby obtaining control inputs that reflect the state of the vehicle's external environment. Furthermore, the target field sequence driving timing of the current frame of the display device is determined based on the ambient light intensity, enabling the field sequence display mode of the current frame to adjust accordingly to changes in external ambient light conditions, thus improving the adaptability of the field sequence display control to environmental changes. Based on this, target touch control parameters matching the field sequence display of the current frame are further determined based on the target field sequence driving timing, ensuring that the configuration of the touch control parameters remains consistent with the field sequence display state of the current frame, thus providing a unified basis for the coordinated execution of subsequent display control and touch control. Subsequently, corresponding sub-field driving signals are output according to the target field sequence driving timing to control the display device to perform field sequence display according to the arrangement and timing relationship of multiple sub-fields, thereby achieving orderly output of the current frame display image. Simultaneously, touch control is performed according to the target touch control parameters to match the touch control with the current frame field sequence display, thereby reducing the impact of changes in the current frame field sequence display on the touch process. Therefore, this application, through ambient light intensity perception, current frame target field sequence driving timing determination, target touch control parameter matching, and step-by-step coordination of display and touch collaborative execution, helps to improve the overall stability and consistency of field sequence display and touch control in complex vehicle environments.

[0007] In one possible implementation, determining the target field sequence driving timing of the current frame of the display device based on the ambient light intensity includes: When the ambient light intensity is greater than or equal to the first brightness threshold, the target field sequence driving timing is determined to be a brightness enhancement driving timing; the brightness enhancement driving timing refers to arranging the red subfield, green subfield, blue subfield and at least one white photonic subfield in a preset order within one field cycle; When the ambient light intensity is less than or equal to the second brightness threshold, the target field sequence driving timing is determined to be a high contrast driving timing. The high contrast driving timing refers to inserting a black field time period between adjacent color subfields in multiple color subfields within one field cycle. The multiple color subfields include: red subfield, green subfield, and blue subfield, wherein the colors corresponding to two adjacent color subfields are different. The first brightness threshold is greater than the second brightness threshold.

[0008] In this embodiment, by selecting between the brightness enhancement driving timing and the high contrast driving timing based on the ambient light intensity, it is beneficial to adapt the current frame field sequence display mode to the external ambient light conditions.

[0009] In one possible implementation, the method further includes: Based on the number of white photonic fields inserted, the insertion ratio of the at least one white photonic field in the brightness enhancement driving timing is determined; According to the insertion ratio, the grayscale gain values ​​corresponding to the red subfield, the green subfield, and the blue subfield are adjusted respectively, and the grayscale gain values ​​are used to adjust the color balance of the display device.

[0010] In this embodiment, by adjusting the grayscale gain values ​​corresponding to the red, green, and blue subfields according to the insertion ratio of the white photonic subfield, it is beneficial to maintain the color balance of the display device while improving the display brightness.

[0011] In one possible implementation, when the target field sequence driving timing is the high-contrast driving timing, the method further includes: During the insertion of the black screen time period, the backlight refresh rate of the current frame of the display device is increased to a first preset frequency; Output the backlight drive clock signal according to the first preset frequency to adjust the backlight refresh rate.

[0012] In this embodiment, by increasing the backlight refresh rate of the current frame of the display device under high contrast driving timing and outputting the backlight driving clock signal at a first preset frequency, it is beneficial to improve the display stability when inserting black screen time periods.

[0013] In one possible implementation, determining the target field sequence driving timing of the current frame of the display device based on the ambient light intensity includes: When the ambient light intensity is between the first brightness threshold and the second brightness threshold, the field sequence driving timing of the current frame of the display device is determined as the target field sequence driving timing, or the field sequence driving timing of the current frame is subjected to transition control. The transition control includes maintaining the field sequence driving timing of the current frame, or adjusting the field sequence driving timing of the current frame according to a preset transition strategy to obtain the target field sequence driving timing.

[0014] In this embodiment, by maintaining or transitionally controlling the field sequence driving timing of the current frame when the ambient light intensity is between the first luminance threshold and the second luminance threshold, it is beneficial to reduce the frequent switching of the field sequence driving timing under critical ambient light conditions.

[0015] In one possible implementation, the target touch control parameters include at least touch scanning parameters, touch reference parameters, and touch transition parameters.

[0016] In this embodiment, by configuring the target touch control parameters as at least touch scanning parameters, touch reference parameters, and touch transition parameters, it is beneficial to achieve touch control that matches the current frame field sequence display from different dimensions.

[0017] In one possible implementation, the target touch scanning parameters are touch scanning pulse output timing sequences; based on the target field sequence driving timing sequence, determining target touch control parameters that match the current frame field sequence display includes: Based on the target field sequence driving timing, determine the touch scanning timing register group corresponding to the target field sequence driving timing; The timing sequence of touch scanning pulse output is determined based on the touch scanning timing register group.

[0018] In this embodiment, by determining the corresponding touch scanning timing register group according to the target field sequence driving timing, and further determining the touch scanning pulse output timing, it is beneficial to improve the matching degree between touch scanning control and the current frame field sequence display.

[0019] In one possible implementation, determining the touch scanning timing register group corresponding to the target field sequence driving timing based on the target field sequence driving timing includes: If the target field sequence driving timing includes at least one white photonic subfield, the corresponding touch scanning timing register group is determined to be the white field configuration table; If the target field sequence driving timing includes a black field time period, determine the corresponding touch scan timing register group as the black field configuration table; If the target field sequence driving timing includes red subfield, green subfield and blue subfield, but does not include white light subfield and black field time periods, determine the corresponding touch scan timing register group as the basic configuration table.

[0020] In this embodiment, different touch scanning timing register groups are selected based on whether the target field sequence driving timing includes a white subfield, a black field time period, or only a red subfield, a green subfield, and a blue subfield, thereby facilitating the rapid switching of touch scanning parameters under different field sequence driving timings.

[0021] In one possible implementation, determining the corresponding touch scan pulse output timing based on the touch scan timing register group includes: If the corresponding touch scan timing register group is a white field configuration table, then the touch scan pulse is shifted to the vertical blanking region after the white photon field ends; If the corresponding touch scan timing register group is a black field configuration table, then increase the sampling frequency corresponding to the touch scan pulse to the preset sampling frequency; If the corresponding touch scan timing register group is the basic configuration table, then the touch scan pulses will be distributed in the vertical blanking area after each color subfield.

[0022] In this embodiment, by setting touch scanning pulse shift, sampling frequency adjustment or pulse distribution mode for different touch scanning timing register groups, it is beneficial to improve the coordination between touch scanning timing and the current frame field sequence display state.

[0023] In one possible implementation, the target touch control parameters are touch reference parameters; determining the target touch control parameters that match the current frame field sequence display based on the target field sequence driving timing includes: The static capacitor reference data corresponding to the basic drive timing, brightness enhancement drive timing and high contrast drive timing are stored in the reference value storage array respectively. Based on the target field sequence driving timing, determine the static capacitance reference data corresponding to the target field sequence driving timing; When the field sequence drive timing is switched, the multiplexer is controlled to select the static capacitor reference data corresponding to the switched field sequence drive timing according to the mode synchronization signal. The static capacitance reference data is input to the reference terminal of the differential amplifier to determine the touch reference parameters of the touch sensing signal.

[0024] In this embodiment, by pre-storing static capacitance reference data corresponding to different driving timings in the reference value storage array, and switching the corresponding reference data when switching the field sequence driving timing, it is beneficial to improve the adaptability of the touch reference parameters to the current frame field sequence display state.

[0025] In one possible implementation, based on the target field sequence driving timing, determining touch transition parameters that match the current frame field sequence display includes: When the field-driven timing changes, determine the target delay and the total number of transition frames during the timing transition period; The number of frames that pass during the timing transition is recorded using a frame counter; The phase interpolator calculates the number of phase delay ticks corresponding to the current transition frame based on the frame number, the total number of transition frames, and the target delay amount. The programmable delay line is controlled according to the phase delay beat number to adjust the delay of the original touch synchronization signal, so as to determine the amount of touch synchronization signal delay corresponding to the current transition frame.

[0026] In this embodiment, by determining the target delay, the total number of transition frames, and the touch synchronization signal delay corresponding to the current transition frame during field-sequence driving timing switching, it is beneficial to improve the smoothness and accuracy of the touch synchronization signal adjustment process.

[0027] In one possible implementation, the step of performing touch control based on the target touch control parameters to match the touch control with the current frame field sequence display includes: The timing of the touch scanning pulse output is controlled according to the touch scanning parameters; Based on the touch reference parameters, control the gating and input of touch reference reference data; The delay of the touch synchronization signal is adjusted according to the touch transition parameters.

[0028] In this embodiment, by implementing touch control based on touch scanning parameters, touch reference parameters, and touch transition parameters respectively, it is beneficial to improve the overall coordination and stability between touch control and the current frame field sequence display.

[0029] A second aspect of this application provides a field sequence display control device, the device comprising: An ambient light acquisition module is used to acquire the ambient light intensity of the vehicle's external environment. The timing determination module is used to determine the target field sequence driving timing of the current frame of the display device based on the ambient light intensity. The parameter determination module is used to determine the target touch control parameters that match the current frame field sequence display based on the target field sequence driving timing. The display control module is used to output corresponding sub-field driving signals according to the target field sequence driving timing. The sub-field driving signals are used to control the display device to perform field sequence display according to the arrangement order and timing relationship of multiple sub-fields. The touch control module is used to perform touch control according to the target touch control parameters so that the touch control matches the current frame field sequence display.

[0030] A third aspect of this application provides a display control system, including: a host computer, a timing controller, and a touch pulse generator; The host computer is used to acquire the ambient light intensity of the external environment of the vehicle, and determine the target field sequence driving timing of the current frame of the display device based on the ambient light intensity. The timing controller is used to output a corresponding sub-field driving signal according to the target field sequence driving timing to control the display device to perform field sequence display according to the target field sequence driving timing, and to select the touch scan timing register group that matches the current frame field sequence display according to the target field sequence driving timing; The touch pulse generator is used to output corresponding touch scanning pulses according to the touch scanning timing register group, and the output terminal of the touch pulse generator is connected to the touch electrode of the in-cell panel in the display device.

[0043] In-vehicle display systems are widely used in dashboards, central control screens, and head-up displays. Field-sequential display technology, due to its lightweight structure and high display efficiency, has been applied to some in-vehicle display solutions. Current field-sequential displays typically output color subfields according to a preset subfield sequence to form the corresponding color image.

[0044] However, in real-world vehicle environments, external lighting conditions change frequently. For example, direct sunlight during the day, low light at night, and situations such as vehicles entering or exiting tunnels or being shaded by trees can all affect the display viewing experience. Furthermore, the driving state, illumination state, and timing state of the display device may change under different operating conditions, making the overall operation more complex. Current technologies still need improvement in terms of display stability, viewing comfort, and overall operational consistency in complex vehicle environments.

[0045] To address the aforementioned issues, this application provides a field sequence display control method, apparatus, and display control system. By acquiring the ambient light intensity of the vehicle's external environment, the field sequence display control is established based on the perception of changes in ambient light in the current scene, thereby obtaining control inputs reflecting the vehicle's external environmental state. Furthermore, the target field sequence driving timing of the current frame of the display device is determined based on the ambient light intensity, enabling the field sequence display mode of the current frame to adjust accordingly to changes in external ambient light conditions, thus improving the adaptability of the field sequence display control to environmental changes. Based on this, the target field sequence driving timing is further determined... The target touch control parameters are determined to match the current frame's field sequence display, ensuring that the configuration of the touch control parameters remains consistent with the current frame's field sequence display state. This provides a unified basis for the coordinated execution of subsequent display control and touch control. Subsequently, based on the target field sequence driving timing, corresponding sub-field driving signals are output to control the display device to perform field sequence display according to the arrangement and timing relationship of multiple sub-fields, thereby achieving orderly output of the current frame's display image. Simultaneously, touch control is performed based on the target touch control parameters to match the current frame's field sequence display, thereby reducing the impact of changes in the current frame's field sequence display on the touch process. Therefore, this application, through ambient light intensity sensing, determination of the current frame's target field sequence driving timing, matching of target touch control parameters, and step-by-step coordination of display and touch collaborative execution, helps improve the overall stability and consistency of field sequence display and touch control in complex in-vehicle environments.

[0046] The following detailed description, with reference to the figures, describes the field sequence display control method, apparatus, system, electronic device, computer-readable storage medium, and computer program product proposed in this application.

[0047] First, it should be noted that the electronic device in this application can be an in-vehicle display device, or an in-vehicle central control device, in-vehicle instrument device, head-up display device, rear-seat entertainment display device, or other in-vehicle electronic device with display control and touch control functions; the system can be deployed on a single hardware platform or distributed among multiple interconnected hardware units. It should also be noted that the "display device" in this application can be a display device that displays images using a field-sequence display method; the "target touch control parameters" can include at least one of touch scanning parameters, touch reference parameters, and touch transition parameters.

[0048] It should also be noted that the descriptions of methods, apparatus, systems, electronic devices, computer-readable storage media, and computer program products in the following embodiments correspond to each other. The technical features disclosed in one embodiment can be applied to other embodiments without conflict. For the steps recorded in the method embodiments, the executing entity can be one or more of a processor, controller, timing controller, display driver unit, and touch control unit in the electronic device. For the modules recorded in the apparatus embodiments, they can be implemented by software, hardware, or a combination of software and hardware.

[0049] See Figure 1 This diagram illustrates the hardware architecture of the display control system provided in an embodiment of this application. The display control system mainly includes an environment perception layer, a logic control layer, a display driver execution layer, and a touch control layer. The environment perception layer collects ambient light information about the vehicle's external environment. The logic control layer determines the target field sequence driving timing of the current frame based on the ambient light information and generates target touch control parameters that match the target field sequence driving timing. The display driver execution layer drives the display device to perform field sequence display according to the target field sequence driving timing. The touch control layer executes touch control that matches the current field sequence display based on the target touch control parameters.

[0050] Specifically, the environment perception layer may include an ambient light sensor (ASL) and a GPIO bus interface. The ASL is used to collect ambient light intensity signals from the vehicle's external environment in real time. Data transmission between the ASL and the subsequent processing unit can be achieved via an I2C or SPI interface to meet the requirement of low-latency ambient light data transmission. In some embodiments, the environment perception layer may also use an onboard camera as the ambient light acquisition terminal, obtaining ambient light intensity information through image brightness analysis; this application does not limit this approach.

[0051] The logic control layer may include a SoC / FPGA logic control module, a mode determination unit, a register (_Reg), an activation register, a raw video signal input terminal, a subfield decomposition engine, a buffer, and a timing controller (TCON). The raw video signal input terminal receives the video data to be displayed; the subfield decomposition engine performs subfield decomposition processing on the raw video signal to obtain subfield data suitable for field-sequence display; the SoC / FPGA logic control module determines the target field-sequence driver timing display device corresponding to the current frame based on the ambient light intensity signal output by the environment perception layer, and performs corresponding subfield data scheduling, color compensation calculations, and touch control parameter generation.

[0052] In some implementations, to facilitate rapid selection and switching of different types of target field sequence driving timings, the logic control layer can also generate a mode selection result corresponding to the target field sequence driving timing of the current frame. The mode selection result can serve as an internal system control identifier, characterizing the field sequence driving timing category adopted by the current frame. For example, when the target field sequence driving timing of the current frame includes red subfields, green subfields, blue subfields, and at least one white light subfield, its corresponding mode selection result can be used as a brightness enhancement type timing identifier; when the target field sequence driving timing of the current frame includes a black field period, its corresponding mode selection result can be used as a high contrast type timing identifier; when the target field sequence driving timing of the current frame only includes red subfields, green subfields, and blue subfields, its corresponding mode selection result can be used as a basic type timing identifier. It should be noted that the mode selection result is mainly used for internal system timing configuration and parameter selection, and does not constitute a limitation on the scope of protection of this application.

[0053] The mode determination unit outputs the mode selection result corresponding to the target field sequence driving timing of the current frame based on the ambient light intensity information; the register _Reg stores the current frame field sequence driving timing and its associated control parameters; the activation register switches the latched control parameters to the active state when preset timing conditions are met. In other words, the timing switching instruction in this application does not directly act on the display driving link or touch control link at any time, but is first written to the register, and then the activation register uniformly takes effect at an appropriate time. This avoids display tearing, flickering, touch timing mismatch, or inconsistency in intra-frame control caused by directly rewriting the timing configuration during frame transmission.

[0054] Furthermore, the timing controller TCON is connected to the SoC / FPGA logic control module to receive timing control parameters and sub-field timing configurations output by the logic control layer, and to generate corresponding field timing drive control signals. In this embodiment, the timing controller TCON supports dynamic timing reconstruction, which can change the arrangement order, triggering order, and duty cycle of multiple sub-fields constituting a frame image according to the target field timing drive timing of the current frame. For example, when the target field timing drive timing of the current frame is a brightness enhancement type field timing drive timing, the timing controller TCON can output a field timing drive timing including red sub-field, green sub-field, blue sub-field, and white light sub-field; when the target field timing drive timing of the current frame is a high contrast type field timing drive timing, the timing controller TCON can output a field timing drive timing that inserts black field time periods between adjacent color sub-fields.

[0055] A buffer is positioned between the logic control layer and the timing controller (TCON) to cache timing streams corresponding to different field sequence drivers. In some implementations, the buffer may include a dual-path buffer structure, used to preprocess timing streams corresponding to different categories of target field sequence driver timings. This way, when changes in ambient light cause changes in the target field sequence driver timing of the current frame, the system can directly call the pre-prepared corresponding timing stream, shortening the response time for mode switching and improving the stability of mode switching.

[0056] To prevent inter-frame inconsistencies in the field sequence driving timing during mode switching, this application also incorporates a hardware synchronization mechanism. Specifically, all timing switching instructions, after being written to the register, are activated only during the field blanking period; physical-level timing changes are also triggered only during the field blanking period. Since the field blanking period is located between adjacent display frames, switching the field sequence driving timing and touch control parameters during this period ensures that the current frame's data output is complete before switching to the timing state corresponding to the next frame, thereby guaranteeing consistency between the display link and the touch link during mode switching.

[0057] The display driver execution layer may include a power management module (PMIC), a Micro LED driver chip (Driver_IC), and a display device. The PMIC provides controlled voltage and / or current regulation to the display driver execution layer; the Driver_IC is connected to a timing controller (TCON) and generates a corresponding drive current based on the PWM / Data signal output by the TCON; the display device outputs a field-sequence display image corresponding to the target display mode under the influence of the drive current.

[0058] In some implementations, the power management module (PMIC) can adjust the power supply state of the display driver execution layer according to the target field sequence driving timing of the current frame. Specifically, when the target field sequence driving timing of the current frame includes a white photonic field, the PMIC can increase the driving voltage V_LED, enabling the white photonic field to output higher pulse brightness under a higher driving voltage; when the target field sequence driving timing of the current frame includes a black field period, the PMIC can reduce the reference current and increase the duty cycle of the black field period to reduce dark-state light leakage and improve display contrast.

[0059] In addition, since the number and arrangement order of subfields constituting a frame image may be different under different current frame target field sequence driving timing, the logic control layer or timing controller TCON in this application can also adjust the pixel clock frequency in real time according to the current subfield configuration so that the duration of each subfield matches the corresponding timing, thereby ensuring that the emission time of each subfield is precisely aligned.

[0060] The touch control layer is used to perform touch control according to target touch control parameters. In some embodiments, the touch control layer may include a touch scanning control unit, a touch reference control unit, and a touch transition control unit. Specifically, the touch scanning control unit is used to determine touch scanning parameters matching the current field sequence display based on the target field sequence driving timing of the current frame; the touch reference control unit is used to determine touch reference parameters matching the current frame field sequence display based on the target field sequence driving timing of the current frame; and the touch transition control unit is used to determine touch transition parameters matching the current field sequence display when the field sequence driving timing switches.

[0061] Furthermore, in some implementations, the timing controller TCON can internally set multiple touch scanning timing register groups, such as a basic configuration table, a white field configuration table, and a black field configuration table. After determining the target field sequence driving timing of the current frame, the logic control layer can synchronously determine the corresponding touch scanning parameters, and the timing controller TCON can select the corresponding touch scanning timing register group to output a touch scanning pulse timing that matches the field sequence display of the current frame. For example, when the target field sequence driving timing of the current frame includes a white light subfield, the touch scanning pulse can be shifted to the vertical blanking area after the white light subfield ends; when the target field sequence driving timing of the current frame includes a black field period, the sampling frequency corresponding to the touch scanning pulse can be increased; when the target field sequence driving timing of the current frame only includes red, green, and blue subfields, the touch scanning pulse can be distributed in the vertical blanking area after each color subfield.

[0062] In some implementations, the touch reference control unit may include a reference value storage array, a multiplexer, and a differential amplifier. The reference value storage array may store static capacitance reference data corresponding to the basic driving timing, brightness enhancement driving timing, and high contrast driving timing, respectively. When the field sequence driving timing is switched, the multiplexer is controlled according to the mode synchronization signal to select the static capacitance reference data that matches the switched field sequence driving timing, and the static capacitance reference data is input to the reference terminal of the differential amplifier so that the current touch sensing signal adopts a reference that matches the current frame field sequence display state.

[0063] In some implementations, the touch transition control unit may include a frame counter, a phase interpolator, and a programmable delay line. When the field-sequence driving timing changes, the touch transition control unit can determine the target delay amount and the total number of transition frames during the timing transition. The frame counter records the number of frames that have passed during the timing transition. The phase interpolator calculates the phase delay tick number corresponding to the current transition frame based on the number of frames, the total number of transition frames, and the target delay amount. Based on the phase delay tick number, the programmable delay line is controlled to adjust the delay of the original touch synchronization signal, so that the touch synchronization signal is smoothly adjusted within multiple transition frames.

[0064] In the above system embodiment, the ambient light intensity signal output by the ambient light sensor is connected to the SoC / FPGA logic control module via an I2C or SPI interface. Based on the ambient light data, the SoC / FPGA logic control module retrieves the timing configuration file corresponding to the current frame's field sequence driving timing from flash memory through address mapping, and loads the timing configuration file into the control register of the timing controller TCON to generate the corresponding target field sequence driving timing. Simultaneously, the SoC / FPGA logic control module also generates corresponding target touch control parameters based on the current frame's field sequence driving timing and synchronously sends these target touch control parameters to the touch control layer. The timing controller TCON outputs corresponding sub-field driving control signals according to the timing configuration file. The Micro LED driver chip Driver_IC drives the display device to perform field sequence display according to the sub-field driving control signals, while the touch control layer executes touch control matching the current frame's field sequence display based on the target touch control parameters. This enables coordinated scheduling of display control and touch control.

[0066] See Figure 2 The diagram shows a schematic flowchart of the field sequence display control method provided in an embodiment of this application; specifically, see [link to relevant documentation]. Figure 2 The method may include the following steps: Step 201: Obtain the ambient light intensity of the vehicle's external environment.

[0067] Here, "vehicle external environment" refers to the lighting environment of the external space where the vehicle is located, used to characterize the current brightness state outside the vehicle. In the embodiments of this application, the vehicle external environment may include different lighting scenarios such as direct sunlight during the day, low light at night, entering and exiting tunnels, and tree shade, and the subsequent determination of the display mode is based on the lighting information corresponding to the external environment.

[0068] "Ambient light intensity" refers to a signal quantity used to reflect the intensity of ambient light outside the vehicle. In this embodiment, ambient light intensity is used to characterize the brightness level of the current external environment. It can be output in real time or periodically by the ambient light acquisition terminal and used as an input signal to subsequently determine the target display mode of the display device.

[0069] In this embodiment, step 201 can be executed as follows: After the display control system is powered on, it continuously collects light intensity data from the vehicle's external environment to obtain the corresponding ambient light intensity signal in real time. Specifically, the ambient light acquisition terminal can periodically detect the vehicle's external environment and output the detected ambient light intensity as the input signal used for subsequent control. The ambient light acquisition terminal can be a photosensitive sensor or an onboard camera; the photosensitive sensor is used to directly collect the light intensity signal from the vehicle's external environment, while the onboard camera is used to acquire images of the external environment and obtain the corresponding ambient light intensity information accordingly. Through the above method, continuous perception of changes in the vehicle's external ambient light can be achieved.

[0070] For example, in one specific instance, the system periodically collects the light intensity signal L of the external environment of the vehicle through an integrated photosensor or an onboard camera. This light intensity signal L is the ambient light intensity described in this application. This ambient light intensity can serve as the input basis for subsequent pattern determination, allowing the system to perform corresponding display control based on the current external environmental conditions.

[0071] Step 202: Determine the target field sequence driving timing display device for the current frame of the display device based on the ambient light intensity; Here, "display device" refers to a display carrier used for field-sequence display. In the embodiments of this application, the display device is used to output the display screen according to the corresponding subfield arrangement order and timing relationship after receiving the corresponding subfield driving signal. That is, step 202 can determine whether to switch the target field-sequence driving timing of the current frame of the display device based on the ambient light intensity, that is, switch from the current field-sequence driving timing to the target field-sequence driving timing. The current field-sequence driving timing is different from the target field-sequence driving timing. For example, the current field-sequence driving timing can refer to the arrangement timing of the pure RGB subfield sequence, or it can be the driving timing that includes white field or black field time periods as described below.

[0072] In this embodiment, the specific execution process of step 202 can be as follows: After obtaining the ambient light intensity of the vehicle's external environment in step 201, the control system determines the display operating state that the current display device should adopt based on the ambient light intensity, and obtains the target field sequence driving timing corresponding to the current external lighting conditions. After the target field sequence driving timing is determined, it can be used as the input basis for subsequently generating target touch control parameters. That is to say, in this step, the system does not directly output specific sub-field driving signals, but first determines the display operating state based on the ambient light intensity, so that subsequent display control and touch control can be carried out around the target field sequence driving timing.

[0073] In one possible implementation, determining the target field sequence driving timing of the display device based on the ambient light intensity includes: Based on the relationship between ambient light intensity and a preset brightness threshold, the target display mode of the display device is determined, and the target field sequence driving timing of the current frame is determined according to the target display mode.

[0074] Among them, the brightness threshold is the threshold corresponding to the ambient light intensity, and their units are the same.

[0075] As an example, the preset brightness threshold in the embodiments of this application may include one or more brightness thresholds. The following comparison takes the preset brightness threshold including a first brightness threshold and / or a second brightness threshold as an example.

[0076] The first brightness threshold can be a threshold used to measure whether to enter daytime mode, i.e., a high brightness threshold, and the second brightness threshold can be a threshold used to measure whether to enter nighttime mode, i.e., a low brightness threshold.

[0077] In this embodiment, only one brightness threshold may be set, such as a first brightness threshold. If the ambient light intensity is greater than or equal to the first brightness threshold, the current scene is determined to be in daytime mode, and the target display mode of the display device is determined to be brightness enhancement mode. Conversely, if the ambient light intensity is less than the first brightness threshold, the current scene is determined to be in nighttime mode or a transition area between daytime and nighttime modes. This embodiment does not limit this.

[0078] In this embodiment, the target display mode can serve as an intermediate determination result for the field-sequence driving timing category under the current ambient light conditions, and be used to further determine the target field-sequence driving timing to be adopted for the current frame. For example, the target display mode may include any one of a brightness enhancement mode, a high contrast mode, and a basic display mode, with different target display modes corresponding to different categories of target field-sequence driving timing.

[0079] The following comparison uses preset brightness thresholds, including a first brightness threshold and / or a second brightness threshold, as an example.

[0080] For example, determining the target field sequence driving timing of the current frame of the display device based on the relationship between ambient light intensity and a preset brightness threshold includes: When the ambient light intensity is greater than or equal to the first brightness threshold, the target field sequence driving timing is determined to be the brightness enhancement driving timing; the brightness enhancement driving timing refers to arranging the red subfield, green subfield, blue subfield and at least one white photon subfield in a preset order within one field cycle. When the ambient light intensity is less than or equal to the second brightness threshold, the target field sequence driving timing is determined to be a high contrast driving timing. The high contrast driving timing refers to inserting a black field time period between adjacent color subfields in multiple color subfields within a field cycle. The multiple color subfields include: red subfield, green subfield, and blue subfield, where the colors corresponding to two adjacent color subfields are different.

[0081] In this embodiment, after acquiring the current ambient light intensity, the system compares the ambient light intensity with a preset brightness threshold and determines the target field sequence driving timing for the current frame of the display device accordingly. Specifically, when the ambient light intensity is greater than or equal to a first brightness threshold, the system determines the target field sequence driving timing for the current frame to be a brightness enhancement driving timing; when the ambient light intensity is less than or equal to a second brightness threshold, the system determines the target field sequence driving timing for the current frame to be a high contrast driving timing. In other words, this embodiment does not first fix the field sequence display mode of the current frame and then correct it based on the ambient light, but directly selects the corresponding target field sequence driving timing for the current frame based on the relationship between the ambient light intensity and the preset brightness threshold.

[0082] Furthermore, in this embodiment, when the target field sequence driving timing of the current frame is determined to be a luminance enhancement driving timing, the field sequence configuration adopted by the current frame includes a red sub-field, a green sub-field, a blue sub-field, and at least one white light sub-field; when the target field sequence driving timing of the current frame is determined to be a high contrast driving timing, the field sequence configuration adopted by the current frame includes a red sub-field, a green sub-field, a blue sub-field, and a black field time period inserted between adjacent color sub-fields. Thus, different sub-field arrangement orders and timing relationships can be adopted for the current frame under different ambient light conditions.

[0083] For example, in one specific instance, when the vehicle is in a bright daylight environment, and the current ambient light intensity is greater than or equal to a first brightness threshold, the system determines the target field sequence driving timing of the current frame of the display device as a brightness enhancement driving timing, so that the current frame is displayed in an arrangement of red subfield, green subfield, blue subfield, and at least one white light subfield within one field cycle. When the vehicle is in a low-light environment such as driving at night or entering a tunnel, and the current ambient light intensity is less than or equal to a second brightness threshold, the system determines the target field sequence driving timing of the current frame of the display device as a high contrast driving timing, so that the current frame is displayed by inserting black field periods between the red, green, and blue subfields within one field cycle. In this way, the field sequence driving timing of the current frame of the display device can be determined accordingly based on the ambient light conditions.

[0084] Figure 3 In the diagram, the horizontal axis represents the ambient light intensity L, and the vertical axis represents the display state. State0 represents the driving state corresponding to night mode, and State1 represents the driving state corresponding to day mode. A second brightness threshold T is set on the horizontal axis. Low and the first brightness threshold T High And the first brightness threshold T High Greater than the second brightness threshold T Low This creates a state-maintaining interval between the two.

[0085] In this embodiment, when the ambient light intensity L is less than or equal to the second brightness threshold T Low At that time, the target field sequence driving timing of the current frame can correspond to the high contrast driving timing in night mode; when the ambient light intensity L is greater than or equal to the first brightness threshold T High At that time, the target field sequence driving timing of the current frame can correspond to the brightness enhancement driving timing in daytime mode; when the ambient light intensity L is at the second brightness threshold T Low and the first brightness threshold T High During this time, the system enters Figure 3 The state holding interval shown allows for either maintaining the current frame's field sequence driving timing unchanged or performing transitional control on the current frame's field sequence driving timing without immediately switching to another driving timing.

[0086] Furthermore, Figure 3 The state-maintaining interval is used to characterize the interval during which the system stabilizes the current frame field sequence driving timing when the ambient light intensity is between two thresholds. By setting this interval, the frequent switching between brightness enhancement driving timing and high contrast driving timing in the current frame can be avoided when the ambient light intensity fluctuates around the two thresholds. In other words, in this embodiment, the first brightness threshold T is used to stabilize the current frame field sequence driving timing. High Second brightness threshold T Low By setting them separately, the switching of the current frame field sequence-driven timing has a certain hysteresis range, thereby improving the stability of the timing switching process.

[0087] For example, in a specific scenario, when a vehicle is driving through a shady area or at the entrance of a tunnel, where light levels are at a critical point of change, the ambient light intensity L may fluctuate within a short period. At this time, if the ambient light intensity L is still within the second brightness threshold T... Low and the first brightness threshold T High In between, the system can maintain the current frame's field sequence driving timing unchanged, or adjust the current frame's field sequence driving timing according to a preset transition strategy. The preset transition strategy can be to use a smooth duty cycle adjustment method to gradually change the pulse width corresponding to the white photon field and / or black field time periods, enabling a stepless transition in display brightness and avoiding obvious brightness jumps between adjacent display frames. This avoids directly switching between the high contrast driving timing corresponding to night mode and the brightness enhancement driving timing corresponding to day mode. Therefore, the target field sequence driving timing of the current frame can remain relatively stable under critical changes in ambient light.

[0088] For example, when the ambient light intensity L gradually increases from a low level and approaches a first brightness threshold T High At the same time, the system can gradually increase the pulse width of the white photon field within one field cycle and / or gradually decrease the pulse width of the black field period, thereby gradually transitioning the current frame field sequence driving timing from a state biased towards high contrast driving timing to a state biased towards brightness enhancement driving timing; correspondingly, when the ambient light intensity L gradually decreases from a high level and approaches the second brightness threshold T Low At the same time, the system can gradually reduce the pulse width of the white photonic field and / or gradually increase the pulse width of the black field time period, so that the current frame field sequence driving timing gradually transitions from a state biased towards brightness enhancement driving timing to a state biased towards high contrast driving timing.

[0089] In one possible implementation, the field sequence display control method further includes: Based on the number of white photonic fields inserted, determine the insertion ratio of at least one white photonic field in the brightness enhancement driving timing. Adjust the grayscale gain values ​​corresponding to the red, green, and blue subfields according to the insertion ratio. The grayscale gain values ​​are used to adjust the color balance of the display device.

[0090] Here, the white light subfield refers to the subfield inserted in a frame of image displayed in the field sequence for outputting white light. In this embodiment, the white light subfield, as one of the multiple subfields constituting a frame of image, together with the red subfield, green subfield, and blue subfield, constitutes the brightness enhancement driving timing sequence.

[0091] Here, "insertion position" refers to the arrangement position of the white photon field relative to the red, green, and blue photon fields within one field cycle; "insertion quantity" refers to the number of white photon fields set within one field cycle. In this embodiment, by determining the insertion position and insertion quantity of the white photon fields, the brightness enhancement driving timing can be obtained.

[0092] See Figure 4 , Figure 4 This illustration shows a field-sequence driving timing diagram corresponding to different target display modes provided in this application embodiment. In this embodiment, when the target display mode is a brightness enhancement mode, the display control system determines the insertion position and number of white light subfields within a field cycle based on the current target display mode, and generates a brightness enhancement driving timing sequence including a red (R) subfield, a green (G) subfield, a blue (B) subfield, and at least one white light (W) subfield. Specifically, the display control system has a color subfield sequence composed of a standard red subfield, a green subfield, and a blue subfield. The display control system can periodically insert white light subfields into the color subfield sequence to add a white light output period to the generated target field-sequence driving timing sequence based on the original color subfields. For example, at least one white light subfield is located after the color subfield sequence.

[0093] The display control system determines the insertion position and number of white photons within a field cycle based on the timing configuration corresponding to the current target display mode. That is, each target display mode corresponds to a timing configuration file (for example, a white field configuration table stores a set of preset timing configuration data for the field sequence driving parameters corresponding to the brightness enhancement mode, i.e., the insertion position and number of white photons). Subsequently, the display device can perform field sequence display according to this target field sequence driving timing.

[0094] For example, in a specific instance, when the ambient light intensity L is determined to be higher than a preset high-brightness threshold T... high At this time, the controller enters brightness enhancement mode and changes the field sequence drive timing, periodically inserting white photonic fields into the standard red, green, and blue sub-field sequence, such as... Figure 4As shown in the upper part, the driving timing can be adjusted from R→G→B to R→G→B→W. Here, W corresponds to the white photon field. By increasing the white photon field within a field cycle, the display device can achieve higher brightness output in brightness enhancement mode. That is, this method utilizes the full-spectrum emission characteristics of Micro LEDs to improve the peak brightness of the overall image, thus meeting the display requirements in bright daylight environments.

[0095] For example, in another specific example, when the ambient light intensity L is determined to be lower than a preset low brightness threshold T... low At this time, the controller enters high contrast mode and executes a dynamic black insertion strategy, such as... Figure 4 As shown in the lower part, black time periods are inserted between adjacent color subfields, adjusting the timing sequence from the original color subfield sequence to R→Black→G→Black→B→Black. Here, Black corresponds to the black time periods. In low-light environments such as nighttime driving or vehicles entering tunnels, the system can use the target field sequence corresponding to this high-contrast mode to drive the timing, so that the display device displays according to the field sequence configuration including the black time periods.

[0096] It is worth noting that the method provided in this application embodiment can achieve: controlling the display device to maintain the field sequence driving timing of the current frame, or switching from the field sequence driving timing of the current frame to the target field sequence driving timing, based on the ambient light intensity.

[0097] For example, if the current field sequence driving timing is a color subfield sequence, i.e., displaying the R subfield, G subfield, and B subfield sequentially, then when the ambient light intensity is greater than or equal to a first brightness threshold, the color subfield sequence switches to a brightness enhancement driving timing that arranges the red subfield, green subfield, blue subfield, and at least one white light subfield in a preset order. When the ambient light intensity is less than or equal to a second brightness threshold, the color subfield sequence switches to a high-contrast driving timing that inserts black time periods between adjacent color subfields, forming the R→Black→G→Black→B→Black sequence. When the ambient light intensity is between the second and first brightness thresholds, the color subfield sequence can be maintained.

[0098] In this embodiment, after the insertion position and number of at least one white photonic field within a field cycle have been determined in the brightness enhancement mode, the display control system can further determine the insertion ratio of the white photonic field in the target field sequence driving timing based on the number of white photonic fields inserted. Specifically, the insertion ratio can be obtained from the number of white photonic fields in the current field cycle, reflecting the degree of introduction of white photonic fields in the current field cycle. After obtaining the insertion ratio, the display control system further adjusts the grayscale gain values ​​corresponding to the red, green, and blue photonic fields according to the insertion ratio, so that the display screen in the brightness enhancement mode maintains the corresponding color balance after the introduction of white photonic fields.

[0099] Furthermore, in this embodiment, adjusting the grayscale gain values ​​corresponding to the red, green, and blue subfields can be understood as follows: after the white subfield is inserted into the original color subfield sequence, the output parameters of the original red, green, and blue subfields are no longer simply kept unchanged. Instead, the grayscale gain values ​​corresponding to each color subfield are adaptively adjusted according to the insertion ratio of the white subfield. In this way, the brightness enhancement field sequence driving includes not only the introduction of the white subfield but also the color matching adjustments made around the introduction of the white subfield.

[0100] For example, in one specific instance, when the timing controller periodically inserts a white light subfield into the standard red, green, and blue color subfield sequence, the display control system can simultaneously execute a color compensation algorithm to appropriately adjust the grayscale gain values ​​corresponding to the red, green, and blue subfields, respectively, to maintain the color fidelity of the image, since the insertion of white light dilutes color saturation. In other words, in daytime brightness enhancement mode, the display control system not only increases the overall brightness by inserting white light subfields, but also adjusts each color subfield accordingly based on the insertion ratio of the white light subfields, thereby ensuring that the display image driven by the brightness enhancement sequence maintains a relatively stable color balance while increasing brightness.

[0101] Specifically, as the white photonic subfield insertion ratio increases, the grayscale gain values ​​corresponding to the red, green, and blue subfields decrease; conversely, as the white photonic subfield insertion ratio decreases, the grayscale gain values ​​corresponding to the red, green, and blue subfields increase or return to the grayscale gain values ​​in the basic display mode. Therefore, the output ratio of the color subfields can be compensated and adjusted while the white photonic subfield participates in the brightness output.

[0102] In this embodiment, the method further includes: During the insertion of the black screen time period, the backlight refresh rate of the current frame of the display device is increased to the first preset frequency; Output the backlight drive clock signal according to the first preset frequency to adjust the backlight refresh rate.

[0103] In this embodiment, the first preset frequency is used as the output frequency of the backlight driving clock signal so that the display device refreshes the backlight at the corresponding frequency under the high contrast driving timing.

[0104] In this embodiment, after the field sequence driving timing of the current frame is determined to be a high-contrast driving timing, the control system, based on generating the corresponding target field sequence driving timing, can further determine a first preset frequency corresponding to the high-contrast driving timing, and output a backlight driving clock signal according to the first preset frequency to adjust the backlight refresh frequency. That is, under the high-contrast driving timing, the system not only forms the corresponding field sequence driving timing by inserting black time periods between adjacent color subfields, but can also further output a matching backlight driving clock signal around the field sequence driving timing, thereby making the backlight refresh process correspond to the current high-contrast driving timing.

[0105] For example, in a specific instance, when the ambient light intensity L is determined to be lower than a preset low brightness threshold T... low After the timing controller enters the high-contrast drive timing sequence, the display control system simultaneously increases the overall field refresh rate, for example, to 240Hz or higher, while executing the dynamic black insertion strategy. Correspondingly, the display control system can determine a first preset frequency corresponding to this high-contrast drive timing sequence and output a backlight drive clock signal according to this first preset frequency to adjust the backlight refresh rate. This ensures that while the display device uses a target field sequence drive timing sequence that includes black screen time periods for display, the backlight drive process also matches the current high-contrast drive timing sequence.

[0106] In one possible implementation, determining the target field sequence driving timing of the current frame of the display device based on the ambient light intensity includes: When the ambient light intensity is between the first brightness threshold and the second brightness threshold, the field sequence driving timing of the current frame of the display device will be determined as the target field sequence driving timing, or the field sequence driving timing of the current frame will be transitionally controlled. The transition control includes maintaining the field sequence driving timing of the current frame or adjusting the field sequence driving timing of the current frame according to a preset transition strategy to obtain the target field sequence driving timing.

[0107] In this embodiment, by maintaining or transitionally controlling the field sequence driving timing of the current frame when the ambient light intensity is between the first luminance threshold and the second luminance threshold, it is beneficial to reduce the frequent switching of the field sequence driving timing under critical ambient light conditions.

[0108] Step 203: Determine the target touch control parameters that match the current frame field sequence display based on the target field sequence driving timing.

[0109] The target touch control parameters refer to the set of parameters used to control the touch process of the current frame. In this embodiment, the target touch control parameters are used to characterize the touch control method that matches the current frame field sequence display state, serving as the basis for subsequent touch control execution.

[0110] In this context, "current frame field sequence display" refers to the field sequence display process performed by the display device according to the target field sequence driving timing corresponding to the current frame. In this embodiment, the current frame field sequence display corresponds to the arrangement order and timing relationship of each sub-field of the current frame, and serves as the basis for determining the target touch control parameters.

[0111] In this embodiment, step 203 can be specifically executed as follows: After the target field sequence driving timing of the current frame is determined, the display control system further generates target touch control parameters that match the field sequence display of the current frame based on the target field sequence driving timing. In other words, this step does not determine the touch control method independently of the display control, but rather configures the touch control parameters corresponding to the current frame based on the actual field sequence driving timing used in the current frame (details of the configuration parameters are described below), so that the touch control process can adapt to the field sequence display state of the current frame. Therefore, subsequent touch control can be executed synchronously around the field sequence display process of the current frame.

[0112] Furthermore, in this embodiment, the target touch control parameters can be parameter configuration results that match the current frame field sequence display. That is, different target field sequence driving timings can correspond to different target touch control parameters; when the target field sequence driving timing of the current frame changes, the corresponding target touch control parameters can also change accordingly. In this way, the touch control of the current frame can be kept consistent with the field sequence display state of the current frame.

[0113] For example, in one specific instance, after the control system determines the target field sequence driving timing for the current frame based on the ambient light intensity, it can further determine target touch control parameters that match the field sequence display of the current frame, for use in subsequent touch control execution. In other words, whatever field sequence driving timing the current frame uses, the subsequent touch control will correspondingly use parameter configurations that match that field sequence driving timing. This ensures that the touch control process of the current frame is coordinated with the field sequence display process of the current frame.

[0114] In another possible implementation, the target touch control parameters include at least touch scanning parameters, touch reference parameters, and touch transition parameters.

[0115] Among them, touch scanning parameters refer to parameters used to limit the timing of touch scanning pulse output; touch reference parameters refer to parameters used to limit the selection and input method of touch reference data; and touch transition parameters refer to parameters used to limit the adjustment method of touch synchronization signal during display timing switching. In this embodiment, the above three types of parameters together constitute the target touch control parameters, which are used to match the touch control with the current field sequence display state.

[0116] See Figure 5 This diagram illustrates the matching relationship between display timing and touch scanning timing for different target display modes provided in the embodiments of this application. Figure 5 The diagram from top to bottom illustrates the timing relationships between display data, backlight enable, and touch scanning in basic display mode, brightness enhancement mode, and high contrast mode. In basic display mode, display data is output in the order of red, green, and blue subfields. The backlight enable coordinates with the corresponding color subfield, and the touch scanning pulses are mainly distributed in the vertical blanking areas after each color subfield. In brightness enhancement mode, a white light subfield is added after the red, green, and blue subfields. The backlight enable outputs white light during the corresponding time period of the white light subfield, and the touch scanning timing is shifted backward relative to the basic display mode to avoid the high-current period corresponding to the white light subfield and shorten the scanning time. In high contrast mode, black field time periods are set between or after adjacent color subfields. The backlight enable is turned off during the black field period, and the touch scanning timing uses a higher sampling frequency to scan during the black field or the corresponding blanking area. Therefore, Figure 5 This reflects that the touch scanning timing can be adjusted according to the display timing and backlight enable status under different target display modes.

[0117] In the above embodiments, the target touch scanning parameters are the touch scanning pulse output timing; based on the target field sequence driving timing, the target touch control parameters that match the current frame field sequence display are determined, including: Based on the target field sequence driving timing, determine the touch scanning timing register group corresponding to the target field sequence driving timing; The timing sequence of touch scanning pulse output is determined based on the touch scanning timing register group.

[0118] The target field sequence driving timing can be determined based on the target display mode.

[0119] In one example, to facilitate rapid identification and register group gating of different categories of target field sequence driving timings within the system, the display control system can also generate a mode selection result corresponding to the target field sequence driving timing. It should be understood that the mode selection result is used to characterize the timing category to which the target field sequence driving timing of the current frame belongs, and serves only as an internal system control identifier, and does not constitute a limitation on the scope of protection of this application.

[0120] Here, "touch scanning parameters" refers to parameters used to define the output mode of touch scanning pulses. In this embodiment, the touch scanning parameters are specifically the touch scanning pulse output timing, used to characterize the output period and output mode of touch scanning pulses in the current field sequence display state.

[0121] The "touch scan timing register set" refers to a pre-configured set of registers used to store touch scan timing parameters under different field sequence driving timings. In this embodiment, the touch scan timing register set corresponds to the target field sequence driving timing and is used to provide the touch pulse generator with the corresponding touch scan timing configuration after the current target field sequence driving timing is determined.

[0122] The "touch scan pulse output timing" refers to the timing arrangement of the touch scan pulse output within one display cycle. In this embodiment, the touch scan pulse output timing is used to define the output position of the field synchronization signal and / or the line synchronization signal under the field sequence driving timing of the current frame, so as to match the touch scan process with the current field sequence display process.

[0123] See Figure 6 , Figure 6 This illustration shows a schematic diagram of touch scanning parameter determination and touch pulse output control provided in an embodiment of this application. In this embodiment, the host computer or ambient light sensor inputs a mode selection signal to the display mode state machine. The mode selection signal is used to characterize the timing category corresponding to the target field sequence driving timing of the current frame. The display mode state machine outputs the current frame mode signal according to the mode selection signal and sends the current frame mode signal to the timing controller. It should be understood that the display mode state machine is a functional module of the host computer, and its function is to generate a control signal for register group selection according to the timing category to which the target field sequence driving timing of the current frame belongs. The timing controller internally has multiple independent touch scanning timing register groups, each corresponding to a different category of target field sequence driving timing. The timing controller selects the touch scanning timing register group corresponding to the target field sequence driving timing of the current frame according to the received current frame mode signal, and determines the corresponding touch scanning pulse output timing according to the selected touch scanning timing register group. Subsequently, the touch pulse generator outputs the corresponding touch scanning pulse according to the touch scanning pulse output timing, and outputs the corresponding field synchronization signal and / or line synchronization signal to the in-cell panel or touch front end for sampling.

[0124] In one possible implementation, determining the touch scanning timing register group corresponding to the target field sequence driving timing based on the target field sequence driving timing includes: If the target field sequence driving timing includes at least one white photonic subfield, determine the corresponding touch scanning timing register group as the white field configuration table; If the target field timing driver includes a black field time period, determine the corresponding touch scan timing register group as the black field configuration table; If the target field timing includes red, green, and blue subfields, but excludes white light subfields and black field time periods, determine the corresponding touch scanning timing register group as the basic configuration table.

[0125] In a specific example, such as Figure 6 As shown, the host computer or ambient light sensor outputs a mode selection signal, Mode_SEL, to characterize the target field sequence driving timing category of the current frame. The display mode state machine generates the current frame mode signal based on the mode selection signal and sends it to the timing controller. The timing controller internally has multiple touch scan timing register groups, such as the touch scan timing register group corresponding to the basic configuration table, the touch scan timing register group corresponding to the white field configuration table, and the touch scan timing register group corresponding to the black field configuration table. The timing controller selects the corresponding touch scan timing register group according to the current frame mode signal and outputs the selected timing configuration to the touch pulse generator. When the target field sequence driving timing of the current frame includes at least one white photonic subfield, the timing controller can control the touch pulse generator to shift the touch scan pulse to the latter two-thirds of the vertical blanking region. Thus, the system can determine the corresponding touch scan timing register group based on the target field sequence driving timing of the current frame and further determine the corresponding touch scan pulse output timing.

[0126] Specifically, in this embodiment, determining the corresponding touch scan pulse output timing based on the touch scan timing register group includes: If the corresponding touch scan timing register group is a white field configuration table, then the touch scan pulse is shifted to the vertical blanking region after the white photon field ends; If the corresponding touch scan timing register group is a black field configuration table, then increase the sampling frequency corresponding to the touch scan pulse to the preset sampling frequency; If the corresponding touch scan timing register group is the basic configuration table, then the touch scan pulses will be distributed in the vertical blanking area after each color subfield.

[0127] In this embodiment, by setting touch scanning pulse shift, sampling frequency adjustment or pulse distribution mode for different touch scanning timing register groups, it is beneficial to improve the coordination between touch scanning timing and the current frame field sequence display state.

[0128] In one possible implementation of this embodiment, the target touch control parameters are touch reference parameters; determining the target touch control parameters that match the current frame field sequence display based on the target field sequence driving timing includes: The static capacitor reference data corresponding to the basic drive timing, brightness enhancement drive timing and high contrast drive timing are stored in the reference value storage array respectively. Based on the target field sequence driving timing, determine the static capacitance reference data corresponding to the target field sequence driving timing; When the field sequence drive timing is switched, the multiplexer is controlled to select the static capacitor reference data corresponding to the switched field sequence drive timing according to the mode synchronization signal. The static capacitance reference data is input to the reference terminal of the differential amplifier to determine the touch reference parameters of the touch sensing signal.

[0129] The reference value storage array refers to a storage structure used to store reference data corresponding to different target field driving timings. In this embodiment, the reference value storage array stores static capacitance reference data corresponding to the basic driving timing, brightness enhancement driving timing, and high contrast driving timing, respectively, so as to call the corresponding touch reference reference under different target field driving timings.

[0130] The static capacitance reference data refers to the reference data that matches the corresponding target field driving timing, and is used as a reference input during touch sensing signal processing. In this embodiment, different target field driving timings correspond to different static capacitance reference data.

[0131] The mode synchronization signal is a control signal used to synchronously trigger the reference data gating operation when the drive timing changes. In this embodiment, the mode synchronization signal is used to control the multiplexer to select the static capacitor reference data corresponding to the switched field sequence drive timing when the field sequence drive timing changes.

[0132] In this context, a multiplexer is a circuit unit used to select and output the current target data from multiple sets of static capacitance reference data. In this embodiment, the multiplexer selects a set of data corresponding to the current target field sequence driving timing from multiple sets of static capacitance reference data output from the reference value storage array, based on the mode synchronization signal.

[0133] In this context, the reference terminal of the differential amplifier refers to the input terminal used by the differential amplifier to receive reference input data. In this embodiment, the selected static capacitance reference data is input to the reference terminal of the differential amplifier as a reference input for the current touch sensing signal processing.

[0134] See Figure 7 This illustration shows a schematic diagram of touch reference parameter determination and reference switching provided in an embodiment of this application. In this embodiment, the reference value storage array can be composed of multiple SRAM cells, which respectively store static capacitance reference data corresponding to the basic driving timing, brightness enhancement driving timing, and high contrast driving timing, for example... Figure 7The Base_RGB, Base_White, and Base_Black values ​​are specified in the data structure. The Mode_Sync signal is input to the control terminal of the multiplexer. Multiple sets of static capacitor reference data from the reference value storage array are input to the multiplexer via the data bus. Once the target field sequence driving timing for the current frame is determined, the multiplexer, under the action of the Mode_Sync signal, selects the static capacitor reference data corresponding to that target field sequence driving timing and outputs it as the current mode Baseline to the reference terminal of the differential amplifier. Simultaneously, the raw touch sensing signal Rx Sensing Data output from the in-cell receiving electrode is input to another input terminal of the differential amplifier. The differential amplifier performs differential processing on the raw touch sensing signal and the current mode Baseline, outputting a clean touch signal, which is then converted by an ADC and used for coordinate calculation.

[0135] Furthermore, in this embodiment, the touch reference parameters are not fixed, but are determined according to the target field sequence driving timing of the current frame. That is, different target field sequence driving timings can correspond to different static capacitance reference data; when the driving timing is switched, the system synchronously triggers the multiplexer through the mode synchronization signal to complete the reference data switching, so that the current reference input is consistent with the switched field sequence driving timing.

[0136] In another possible implementation of this method, based on the target field sequence driving timing, touch transition parameters that match the current frame field sequence display are determined, including: When the field-driven timing changes, determine the target delay and the total number of transition frames during the timing transition period; The number of frames that pass during the timing transition is recorded using a frame counter; The phase interpolator calculates the number of phase delay ticks corresponding to the current transition frame based on the frame number, the total number of transition frames, and the target delay. The programmable delay line is controlled by the phase delay beat number to adjust the delay of the original touch synchronization signal in order to determine the amount of touch synchronization signal delay corresponding to the current transition frame.

[0137] The touch transition parameter refers to the parameter used to characterize the adjustment mode of the touch synchronization signal when the target field sequence driving timing changes. In this embodiment, the touch transition parameter is used to describe how the touch synchronization signal gradually adjusts from the current state to the state after the change during the target field sequence driving timing switching process.

[0138] The target delay refers to the target delay value that the original touch synchronization signal needs to be adjusted to during the target field-driven timing switch. In this embodiment, the target delay is used to characterize the delay change magnitude corresponding to the transition of the touch synchronization signal from the current timing state to the target timing state.

[0139] The total number of transition frames refers to the total number of frames used to complete the touch synchronization signal delay adjustment during the target field sequence driving timing switch. In this embodiment, the total number of transition frames is used to limit how many frames the touch synchronization signal delay adjustment spans.

[0140] The frame counter is a circuit unit used to record the number of frames that have passed during the target field sequence driving timing transition. In this embodiment, the frame counter is used to output the frame number of the current transition frame throughout the entire transition process.

[0141] Here, the phase delay tick number refers to the delay adjustment amount corresponding to the current transition frame. In this embodiment, the phase delay tick number is calculated by the phase interpolator based on the current frame number, the total number of transition frames, and the target delay amount, and is used to control the delay adjustment of the programmable delay line.

[0142] In this context, a programmable delay line refers to a circuit unit that applies an adjustable delay to the input signal. In this embodiment, the programmable delay line is connected in series in the transmission path of the original touch synchronization signal, and is used to adjust the delay of the original touch synchronization signal according to the phase delay beat number corresponding to the current transition frame.

[0143] The touch synchronization signal delay refers to the delay value of the original touch synchronization signal after delay adjustment in the current transition frame. In this embodiment, the touch synchronization signal delay is used to characterize the specific delay state of the touch synchronization signal in the current transition frame.

[0144] See Figure 8 , Figure 8 This illustration shows a schematic diagram of touch transition parameter determination and synchronization signal smoothing adjustment provided in an embodiment of this application. In this embodiment, when the target field sequence driving timing changes, a timing change trigger signal is input to a frame counter to initiate the transition frame counting process. The frame counter records the number of frames elapsed during the timing transition and outputs the current frame number to a phase interpolator. The phase interpolator calculates the phase delay beat number corresponding to the current transition frame based on a preset total number of transition frames and a target delay amount, combined with the current frame number. Subsequently, the programmable delay line adjusts the original touch synchronization signal according to the phase delay beat number, thereby obtaining the touch synchronization signal delay amount corresponding to the current transition frame. After the above processing, a field synchronization signal and / or a line synchronization signal corresponding to the current transition state can be output.

[0145] For example, in a specific example, such as Figure 8As shown, the timing switch trigger signal (Trigger) is input to the frame counter, which records the number of frames n = 1, 2, 3…N during the transition. The phase interpolator calculates the delay amount Delay(n) of the current frame based on the frame number n, the total number of transition frames N, and the target delay amount. Subsequently, the programmable delay line adjusts the original touch synchronization signal according to the delay amount corresponding to the current frame and outputs a smooth transition field synchronization signal and / or line synchronization signal. When the system switches from the basic display driving timing to the brightness enhancement driving timing or the high contrast driving timing, the programmable delay line can increase or decrease the delay time of the touch pulse frame by frame according to the number of beats calculated in real time by the phase interpolator, so that the touch scanning window is gradually adjusted to the target position within multiple transition frames.

[0146] Step 204: Output the corresponding sub-field driving signal according to the target field sequence driving timing to control the display device to perform field sequence display according to the arrangement order and timing relationship of multiple sub-fields; In this embodiment, the display control system can load a timing configuration corresponding to the target field sequence driving timing of the current frame into the timing controller, which then outputs a corresponding sub-field driving control signal based on the timing configuration. Subsequently, the driver chip generates a corresponding driving signal based on the sub-field driving control signal, controlling the display device to complete the corresponding light emission display within the time period corresponding to different sub-fields. In this way, the display device can perform field sequence display according to the target field sequence driving timing determined in step 202.

[0147] Step 205: Perform touch control according to the target touch control parameters so that the touch control matches the current frame field sequence display.

[0148] In this embodiment, step 205 can be specifically executed as follows: After determining the target touch control parameters in step 203, the control system executes touch control that matches the current display sequence according to the target touch control parameters. Specifically, the target touch control parameters may include touch scanning parameters, touch reference parameters, and touch transition parameters; wherein, the system can control the output timing of the touch scanning pulse according to the touch scanning parameters, control the gating and input of the touch reference data according to the touch reference parameters, and control the delay adjustment of the touch synchronization signal according to the touch transition parameters, so that the touch control process is consistent with the current display sequence state.

[0149] Specifically, based on the target touch control parameters described in step 203, step 205 may include: The timing of the touch scanning pulse output is controlled according to the touch scanning parameters; Based on the touch reference parameters, control the gating and input of touch reference reference data; The delay of the touch synchronization signal is adjusted according to the touch transition parameters.

[0150] In this embodiment, touch control is not executed independently of display control, but is synchronously adjusted around the field sequence display state corresponding to the current target display mode. That is, when the display device performs field sequence display according to the target field sequence driving timing, the scanning timing, reference base, and synchronization signal delay in the touch link can also be adjusted accordingly based on the determined target touch control parameters so that the touch control matches the current field sequence display.

[0151] In the above method embodiments, the target field sequence driving timing of the display device is determined by obtaining the ambient light intensity of the vehicle's external environment, and the target touch control parameters are further determined, so that the display control and touch control can be configured collaboratively around the same target field sequence driving timing, thereby improving the stability and consistency of field sequence display in complex vehicle environments.
