[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] The terms "first", "second" etc. in the embodiments of the present application are used to distinguish similar objects, and need not be used to describe a specific order or sequential order. In addition, the terms "include" and "have" and any variation thereof are intended to cover non-exclusive inclusions, for example, the process, method, system, product or equipment comprising a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment. In addition, "and / or" is used in the present application to represent at least one of connected objects, such as A and / or B and / or C, representing the inclusion of separate A, separate B, separate C, and A and B all exist, B and C all exist, A and C all exist, and 7 situations that A, B and C all exist.

[0049] An embodiment of the present application provides a display control method, which is applied to a display device.

[0050] like Figure 1 As shown, in one embodiment, the method:

[0051] Step 101: loading first display driving data and second display driving data;

[0052] Step 102: receiving a state switching instruction when the display device is in a first display state based on the first display driving data;

[0053] Step 103: In response to the state switching instruction, the display driving data of the display device is switched from the first display driving data to the second display driving data, so as to switch the display device to a second display state based on the operation of the second display driving data.

[0054] In an exemplary embodiment of the present application, the display device can be set in different display devices such as vehicles, mobile phones, tablet computers, personal computers, smart watches, etc., and the hardware of the display device supports different display states.

[0055] The display device includes at least a first display state and a second display state. In one exemplary embodiment, one of the first display state and the second display state is a shared display mode, and the other is an anti-peeping display mode.

[0056] In some other embodiments, the first display state and the second display state may also be display states with different refresh frequencies.

[0057] like Figure 2 As shown, in one of the exemplary embodiments, the display device is applied to a vehicle for exemplary illustration, and the display device on the vehicle includes a dashboard and HUD for displaying vehicle driving information, a CID arranged on the center console, and a CDD arranged in front of the co-pilot seat.

[0058] During use, the information displayed by the CID and CDD may change. For example, the co-pilot may use the CDD to watch entertainment videos, and prompt information may appear on the CID. These contents may distract the driver and affect driving safety. For this reason, the relevant technology supports switching the display mode of the CID and CDD between a shared display mode and an anti-peeping display mode.

[0059] In some embodiments, the switching of the display state may refer to the switching between the shared display mode and the anti-peeping display mode, wherein when the display modes are different, the refresh frequencies before and after the switching may be the same or may be different.

[0060] The switching of display status may also refer to the switching between different refresh rates in the same display mode. For example, in the shared display mode, the refresh rate of the display device is switched from 90Hz to 120Hz. Obviously, the switching of display status may also refer to the switching between different refresh rates in the anti-peeping display mode.

[0061] In the technical solution of this embodiment, the display driving data corresponding to a certain display state refers to various display driving data required in the display mode, specifically including but not limited to gamma data, compensation data, GOA data, etc.

[0062] Exemplarily, the first display driving data refers to the gamma data, compensation data, GOA data, etc. corresponding to the first display state, and the second display driving data refers to the gamma data, compensation data, GOA data, etc. corresponding to the second display state. . .

[0063] like Figure 3 As shown, in the related art, the display driving data required for each display state is usually stored separately using an independent memory (for example, a flash memory). For example, the display data in the shared mode is stored in the memory 1, and the display data in the anti-peeping mode is stored in the memory 2. When in a certain display mode, the corresponding memory is powered on independently and provides the corresponding display driving data. In this way, the display driving data corresponding to a certain display state will only be called when switching to the display mode.

[0064] Please continue reading Figure 3 For example, a certain display device supports an anti-peeping display mode and a shared display mode. The processing method in the related art is that when the display device is in the anti-peeping display mode, only the storage 2 corresponding to the anti-peeping display mode is controlled to be powered on to provide the required display driving data. During operation, the storage 1 that stores the display driving data required for the shared display mode is powered off and in a non-working state.

[0065] When a switching instruction is received from the application end and the display device is switched to the shared display mode, the application end sends a reset signal to the logic board Tcon, and the display device performs an initialization operation. The memory 1 that stores the display driver data of the shared display mode is powered on through the selection module to load the display driver data required for the shared display mode. This initialization process will cause the display device to have a black screen, flicker, and sudden changes in brightness and color.

[0066] However, the technical solution of this embodiment does not provide multiple memories and selection modules, but stores the display driving data in the same memory. During implementation, the memory storing the display driving data is powered on, and the display driving data therein is loaded at the same time.

[0067] Exemplarily, if the display device supports a shared display mode and an anti-peeping display mode, the display driving data of the shared display mode and the display driving data of the anti-peeping display mode are loaded simultaneously.

[0068] Exemplarily, the display device supports multiple display modes with different refresh rates, for example, a 60 Hz shared display mode, a 90 Hz shared display mode, and a 120 Hz shared display mode, and the display driving data of the 60 Hz shared display mode, the display driving data of the 90 Hz shared display mode, and the display driving data of the 120 Hz shared display mode are loaded simultaneously.

[0069] Exemplarily, the display device supports a 60 Hz shared display mode, a 90 Hz shared display mode, a 120 Hz shared display mode, a 60 Hz anti-peeping display mode, a 90 Hz anti-peeping display mode, and a 120 Hz anti-peeping display mode, and the display driving data required for the above modes are loaded at the same time.

[0070] In this embodiment, the shared display mode refers to a display mode in which the visual angle of the display device is larger. It can be understood that the content displayed by the CDD can also be observed in the main driving position; the anti-peep display mode can also be called the privacy display mode. In this display mode, the visual angle of the display device is relatively small. It can be understood that in this anti-peep display mode, the content displayed by the CDD cannot be observed in the main driving position, thereby avoiding the driver in the main driving seat being distracted by observing the CDD and affecting the driving safety of the vehicle.

[0071] In some embodiments, in response to the state switching instruction, switching the display driving data of the display device from the first display driving data to the second display driving data includes:

[0072] Responding to a state switching instruction from an application end of the display device;

[0073] Second display driving data from the display driving data preloaded in the memory is selected, and the display device is driven to display an image based on the second display driving data.

[0074] The application end (AP) in this embodiment refers to an application program or a system application that issues a control instruction for issuing a mode switching instruction.

[0075] In one embodiment, the state switching instruction for switching the display mode may be actively issued by the user. For example, the user may actively switch the display mode of the display device through a voice instruction, a touch instruction, or a key instruction.

[0076] In another embodiment, the state switching instruction can also be automatically issued by the display device when a specific condition is met. Taking a vehicle as an example, when implemented, it can be set to automatically issue a state switching instruction when the vehicle is in a driving gear or a forward gear, and switch the display state of the CID and CDD to an anti-peeping display mode to avoid distracting the driver; it can also be set to automatically switch to an anti-peeping display mode when the vehicle's driving speed is greater than a certain speed threshold. For example, it can be set to different speed thresholds such as 20KM / h, 30KM / h, etc. as needed.

[0077] After receiving the state switching instruction, in response to the state switching instruction, the display driving data of the display device is switched from the first display driving data to the second display driving data, so as to switch the display device to a second display state based on the operation of the second display driving data.

[0078] In some embodiments, the display device includes a memory, display driver storage data corresponding to different display states are stored in the same memory, and the display driver storage data corresponding to different display states are loaded when the memory is powered on.

[0079] In the technical solution of the present embodiment, the first display driving data and the second display driving data are both in a loading state. For example, the first display driving data and the second display driving data may be loaded when the display device is powered on or the display device is started. Therefore, during the operation of the display device, the corresponding display driving data may be directly called for display control. In this way, during the switching of the display driving data, there is no need to control the initialization of the display device and the power-on and power-off of the corresponding memory, thereby avoiding abnormal conditions such as a black screen and flickering in the display device that affect the display effect.

[0080] In some embodiments, after step 103, the method further includes:

[0081] The first display driving data is controlled to maintain a loading state.

[0082] In the technical solution of this embodiment, after the display state is switched, the corresponding display driver data remains in a loaded state, so that the display device can switch back to the original display mode without abnormal displays such as black screen and flickering, thereby improving the smoothness and convenience of switching between different display states.

[0083] In some embodiments, the step 103 includes:

[0084] When the white balance color coordinates and the gamma curve remain unchanged, the display driving data is switched from the first display driving data to the second display driving data.

[0085] In the technical solution of this embodiment, during the switching of display driving data, it is necessary to match the display driving data of different display modes to keep the white balance color coordinates and the gamma curve unchanged during the state switching process. In this way, when the display state is switched, the color and brightness of the picture can be kept without sudden changes, and seamless switching can be achieved, thereby further improving the display effect and user experience.

[0086] In the technical solution of this embodiment, specific white balance color coordinates and gamma curves may be used, wherein the gamma curve may be a 2.2 gamma curve (2.2Gamma Curve) with 2.2 as the recommended gamma value. Next, gamma matching is performed for different display states. For example, the display driving data corresponding to the specific white balance color coordinates and gamma curves in the privacy mode and the sharing mode may be determined respectively. In this way, it is possible to ensure that the white balance color coordinates and the gamma curve remain unchanged during the state switching process.

[0087] In some of the embodiments, when the display device needs to switch between different display modes, it is necessary to further confirm whether the refresh rates are the same.

[0088] In one embodiment, one of the first display state and the second display state is a shared display mode, and the other is an anti-peeping display mode. In this embodiment, only the first display state is a shared display mode, and the second display state is an anti-peeping display mode for exemplary description.

[0089] After step 102, the method further includes:

[0090] Acquire a second refresh frequency corresponding to the second display state;

[0091] When the second refresh frequency is different from the first refresh frequency corresponding to the first display state, the display device is controlled to switch between the shared display mode and the anti-peeping display mode while the refresh frequency remains unchanged.

[0092] In the technical solution of this embodiment, if the refresh frequencies of the first display state and the second display state are the same, for example, the first display state is a shared display mode of 90 Hz, and the second display state is an anti-peeping display mode of 90 Hz, then the display driving data can be switched directly, that is, the display data is directly switched from the first display driving data to the second display driving data, thereby switching the display state to the second display state.

[0093] When the refresh frequencies of the first display state and the second display state are different, it is necessary to control the display device to switch between the shared display mode and the anti-peeping display mode at the same refresh frequency.

[0094] In one embodiment, the step of controlling the display device to switch between the shared display mode and the anti-peeping display mode while keeping the refresh frequency unchanged includes:

[0095] Switching the display driving data of the display device from the first display driving data to third display driving data corresponding to a third display state;

[0096] The display driving data of the display device is switched from the third display driving data to the second display driving data.

[0097] During implementation, the third display driving data, the first display driving data and the second display driving data are loaded simultaneously, the first display state and the third display state are both shared display modes or both anti-peeping display modes, the second display state and the third display state, one is a shared display mode and the other is an anti-peeping display mode, the first display state and the third display state have different refresh frequencies, and the second display state and the third display state have the same refresh frequencies.

[0098] In this embodiment, the refresh rate is switched first and then the display mode is switched.

[0099] Specifically, exemplarily, the first display state is a 90 Hz shared display mode, the second display state is a 120 Hz anti-peeping display mode, and the third display state is a 120 Hz shared display mode.

[0100] The display modes and refresh frequencies of the first display state and the second display state are different; the display modes of the first display state and the third display state are the same, but the refresh frequencies are different; the refresh frequencies of the third display state and the second display state are the same, but the display modes are different.

[0101] During implementation, the first display driving data, the second display driving data and the third display driving data are loaded simultaneously.

[0102] When it is necessary to switch the display state of the display device from the first display state to the second display state, the display driving data is first switched from the first display driving data to the third display driving data, that is, while keeping the display mode as the shared display mode unchanged, the refresh frequency is switched from 90 Hz to 120 Hz, which is the same as the refresh frequency of the second display state.

[0103] Next, the display driving data is switched from the third display driving data to the second display driving data, that is, while keeping the refresh frequency at 120 Hz unchanged, the display mode is switched from the shared display state to the anti-peeping display mode.

[0104] In another embodiment, the step of controlling the display device to switch between the shared display mode and the anti-peeping display mode while keeping the refresh frequency unchanged includes:

[0105] Switching the display driving data of the display device from the first display driving data to fourth display driving data corresponding to a fourth display state;

[0106] The display driving data of the display device is switched from the fourth display driving data to the second display driving data.

[0107] In this embodiment, the fourth display driving data, the first display driving data and the second display driving data are loaded simultaneously, the second display state and the fourth display state are both shared display modes or both are anti-peeping display modes, the first display state and the fourth display state, one is the shared display mode and the other is the anti-peeping display mode, the refresh frequencies of the first display state and the fourth display state are the same, and the refresh frequencies of the second display state and the fourth display state are different.

[0108] In another embodiment of the present application, different from the above embodiment, the display mode may be switched first and then the refresh frequency may be switched.

[0109] Exemplarily, the first display state is a 90 Hz shared display mode, the second display state is a 120 Hz anti-peeping display mode, and the fourth display state is a 90 Hz anti-peeping display mode.

[0110] That is, the display modes and refresh frequencies of the first display state and the second display state are different; the display modes of the second display state and the fourth display state are the same, but the refresh frequencies are different; the refresh frequencies of the first display state and the fourth display state are the same, but the display modes are different.

[0111] During implementation, the first display driving data, the second display driving data and the fourth display driving data are loaded simultaneously.

[0112] When it is necessary to switch the display state of the display device from the first display state to the second display state, the display driving data is first switched from the first display driving data to the fourth display driving data, that is, while keeping the refresh frequency at 90 Hz unchanged, the display mode is switched from the shared display state to the anti-peeping display mode.

[0113] Next, the display driving data is switched from the fourth display driving data to the second display driving data, that is, the refresh rate is switched from 90 Hz to 120 Hz while keeping the display mode as the anti-peeping display mode.

[0114] In some embodiments, the display driving data includes one or more of image quality compensation data, temperature compensation data, gamma data, and GOA data, and switching the display driving data of the display device from the first display driving data to the second display driving data includes:

[0115] One or more of the image quality compensation data, temperature compensation data, gamma data and GOA data corresponding to the first display state are switched to the image quality compensation data, temperature compensation data, gamma data and GOA data corresponding to the second display state.

[0116] like Figure 4 and Figure 5 As shown, during implementation, the video data input is input from the system-level chip SOC to the driver circuit board TCON (logic board). In this embodiment, the video data is input to TCON through the input interface and then processed by TCON. Among them, TCON includes display driver data for storing different display states. In this embodiment, the display driver data for different display states are encapsulated in the corresponding IP core.

[0117] like Figure 5As shown, in response to a state switching instruction, the display driving data required for the corresponding sharing mode or anti-peeping mode and the display driving data corresponding to different display frequencies are selected according to the state switching instruction, so as to process the input video data and output the processed video data to the display panel to realize display control.

[0118] In some of the embodiments, the display device may further provide different image quality compensation methods, and the display driving data includes image quality compensation data of the different image quality compensation methods.

[0119] In an exemplary embodiment, the image quality compensation methods may include different methods such as standard mode BOIS_DE, vivid mode BOIS_C, bright mode BOIS_L, movie mode BOIS_M, energy saving mode BOIS_O, game mode BOIS_H, photo mode BOIS_P, etc.

[0120] Furthermore, for different image quality compensation methods, compensation data in the shared mode and compensation data in the anti-peeping mode are provided respectively. For example, the image quality compensation data of the standard mode in the shared mode is S_BOIS_DE, and the image quality compensation data of the standard mode in the anti-peeping mode is P_BOIS_DE; the image quality compensation data of the vivid mode in the shared mode is S_BOIS_C, and the image quality compensation data of the vivid mode in the anti-peeping mode is P_BOIS_C, and so on.

[0121] These image quality compensation data are usually packaged into corresponding IP cores. Figure 3 In the figure, the block corresponding to each image quality compensation data can represent a memory unit that encapsulates the corresponding image quality compensation data. For example, it can be a static random access memory (SRAM) or a register REG. During implementation, these image quality compensation data are loaded simultaneously when the memory is powered on.

[0122] During implementation, in response to the state selection instruction and the working mode of the display mode selected by the user, the corresponding image quality compensation data is called.

[0123] Exemplarily, if the user selects the game mode and the current working state of the display device is the sharing mode, S_BOIS_H is called as the image quality compensation data in the display driving data according to the corresponding state switching instruction.

[0124] In some embodiments, the display driving data also includes gamma data. Further, in response to the state switching instruction, the corresponding gamma data is selected in the DGA (Digital Gamma Adjusted) stage. Specifically, if the mode is switched to the sharing mode, the corresponding switching uses the shared gamma data S_Gamma required for the sharing mode, and if the mode is switched to the privacy mode, the corresponding switching uses the privacy gamma data P_Gamma required for the privacy mode.

[0125] In some embodiments, the display driving data also includes temperature compensation data. In this embodiment, in order to further ensure the image quality, the color deviation of the module at different temperatures is further considered and temperature compensation is performed. When the display device is in the sharing mode, the shared Gamma temperature compensation data S_COMP is selected for temperature compensation, and when the display device is in the privacy mode, the privacy Gamma temperature compensation data P_COMP is selected for temperature compensation.

[0126] like Figure 6 As shown, during implementation, multiple sets of image quality compensation data, multiple sets of Gamma data, and multiple sets of Gamma temperature compensation data corresponding to different display states are loaded simultaneously, and in response to the state switching instruction for the selection of display states such as display mode and refresh frequency, the corresponding Gamma data, image quality compensation data, and temperature compensation data are called to realize the switching of the display state.

[0127] The digital gamma correction module is provided to the output interface and the GOA unit through the control module DGEN. At the same time, in response to the state switching instruction, the corresponding shared mode GOA data S_GOA or privacy mode GOA data P_GOA is provided to the GOA unit, so that the video data and GOA signal are finally output to the source driver (SD IC).

[0128] During implementation, multiple sets of corresponding driving timings (GOA Timing) can be provided according to different refresh frequencies supported by the display device and the supported sharing modes and privacy modes, so as to meet the driving requirements of different display states.

[0129] like Figure 7As shown, it can be understood that, in the technical solution of this embodiment, when switching between the same display modes, different refresh frequencies can be switched. For example, the shared display mode can be switched between 60Hz, 90Hz and 120Hz in pairs; when switching between different display modes, it is necessary to switch while keeping the same refresh frequency. For example, if the 60Hz shared display mode is to be switched to the anti-peeping display mode, it can only be directly switched to the 60Hz anti-peeping display mode. That is to say, if the display state is to be switched from the 60Hz shared display state to the 120Hz anti-peeping display mode, the refresh frequency can be switched to 120Hz first, and then the display mode can be switched. Alternatively, the refresh frequency can be kept the same and the anti-peeping display mode can be switched to the 60Hz anti-peeping display mode first, and then the anti-peeping display mode can be switched to the 120Hz anti-peeping display mode.
