[0061] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0062] First, an application scenario of the present disclosure is introduced. The present disclosure is applied in a scenario of transmitting display data between multiple displays in a vehicle cabin.

[0063] The display screens of vehicle cockpit displays are getting bigger and bigger, and can display more colorful content. Since multiple displays can be installed in the cockpit, in related technologies, multi-screen interaction can also be performed to synchronize entertainment and information between different displays in the cockpit, making the content displayed on the display screen more diverse, while also improving the user experience during riding or driving.

[0064] In the prior art, the data to be transmitted can be sent to the display that needs interactive display through the CAN bus, for example, the road information such as turns and cameras of the multimedia display can be transmitted to the instrument display. The data transmitted in this way is generally simple, with less content, slow update speed and low transmission efficiency.

[0065] In addition, the display data to be transmitted can also be sent to the display that needs interactive display through LVDS (Low-Voltage Differential Signaling). The data content transmitted in this way is richer and more diverse, and the user experience is higher, but this transmission method can only transmit data in one direction. Once the transmission direction is determined, it cannot be changed, resulting in low transmission efficiency.

[0066] In order to solve the above problems, the present disclosure provides a method, system and vehicle for display control; the system includes: an instrument display, a multimedia display and a half-duplex low voltage differential signal (LVDS) transmission channel; the instrument display is connected to the multimedia display through the half-duplex LVDS transmission channel; the instrument display is used to respond to a first touch operation of the user on the instrument display, and send first display data of the instrument display to the multimedia display through the half-duplex LVDS transmission channel; the multimedia display is used to respond to a second touch operation of the user on the multimedia display, and send second display data of the multimedia display to the instrument display through the half-duplex LVDS transmission channel; bidirectional transmission of display data of the two displays is achieved through the half-duplex LVDS transmission channel, thereby optimizing the device structure, reducing the device cost, improving the efficiency of data transmission, and enhancing the interactive effect in the cockpit during riding or driving.

[0067] Figure 1 FIG. 1 is a structural block diagram of a display control system according to an exemplary embodiment. Figure 1 As shown, the system is applied to a vehicle, and the system 100 includes an instrument display 110, a multimedia display 120, and a half-duplex LVDS transmission channel 130; the instrument display 110 is connected to the multimedia display 120 via the half-duplex LVDS transmission channel 130;

[0068] The instrument display 110 is used to send first display data of the instrument display to the multimedia display 120 through the half-duplex LVDS transmission channel 130 in response to a first touch operation of the user on the instrument display;

[0069] The multimedia display 120 is used to send the second display data of the multimedia display to the instrument display 110 through the half-duplex LVDS transmission channel 130 in response to the second touch operation of the user on the multimedia display.

[0070] For example, the first display data may be the current display content of the instrument display, such as road information or navigation information. The second display data may be the current display content of the multimedia display, such as image information, navigation information or video information. The display screens of the instrument display and the multimedia display may be touch display screens or optical sensing display screens. The first touch operation and the second touch operation may be touch operations or gesture operations, which are not limited here. For example, the touch operation may be a click operation or a slide operation on the display screen. In this way, bidirectional transmission of display data of the instrument display and the multimedia display may be achieved through a half-duplex LVDS transmission channel, thereby improving the efficiency of data transmission and improving user experience.

[0071] In some embodiments, the multimedia display may include multiple displays; the controller is also used to divide the first display data into multiple target display data according to the number of the multimedia displays; determine the target display data corresponding to each multimedia display based on the position information of each multimedia display in the vehicle; and send the target display data to the corresponding multimedia display.

[0072] For example, the multimedia display may include a central control multimedia display, a windshield display, a sunroof display, or a rear seat multimedia display, etc., which are not limited here. By displaying different parts of the content of the same screen on different displays, these contents can form the same screen, thereby creating a dynamic atmosphere, improving the comfort in the cabin, and giving the user an immersive feeling.

[0073] According to the above scheme, bidirectional transmission of display data of two displays is realized through the half-duplex LVDS transmission channel, which optimizes the equipment structure, reduces the equipment cost, improves the efficiency of data transmission, and enhances the interactive effect in the cockpit during riding or driving.

[0074] In some embodiments, Figure 2As shown, the half-duplex LVDS transmission channel 130 includes a first LVDS driver 131, a first LVDS receiver 132, a second LVDS driver 133 and a second LVDS receiver 134; the first LVDS driver and the second LVDS receiver are respectively connected to the instrument display; the second LVDS driver and the first LVDS receiver are respectively connected to the multimedia display; the first LVDS driver is connected to the first LVDS receiver; the second LVDS driver is connected to the second LVDS receiver; data is transmitted between the first LVDS driver and the first LVDS receiver, and between the second LVDS driver and the second LVDS receiver through the same transmission channel; the half-duplex LVDS transmission channel is used to send the first display data to the first LVDS receiver through the first LVDS driver in response to the first touch operation; or, to send the second display data to the second LVDS receiver through the second LVDS driver in response to the second touch operation.

[0075] For example, the half-duplex LVDS transmission channel may be a half-duplex LVDS transmission structure, such as Figure 3 As shown, the half-duplex LVDS transmission structure can be composed of a first LVDS driver D1, a first LVDS receiver R1, a second LVDS driver D2 and a second LVDS receiver R2, and two load resistors R T The first driver D1 and the first receiver R1, as well as the second driver D2 and the second receiver R2, are combined to transmit data through the same transmission channel. In this way, bidirectional data transmission can be achieved through a single channel, which reduces equipment costs and improves transmission efficiency; and bidirectional data transmission can also be performed in time periods. When the first LVDS driver sends data to the first LVDS receiver, the second LVDS driver and the second LVDS receiver are equivalent to being disconnected and unable to transmit data, and vice versa.

[0076] In other embodiments, when there are multiple multimedia displays, the first display data can be transmitted to each multimedia display through a multi-point half-duplex LVDS transmission structure. For example, the number of the multimedia displays can be in the range of 1-10, for example, 1, 2, 3, 5 or 10, etc., which is not limited here. For example, when the number of the multimedia displays is 3, the multi-point half-duplex LVDS transmission structure can be as follows: Figure 4 As shown, the first LVDS driver D1, the first LVDS receiver R1, the second LVDS driver D2, the second LVDS receiver R2, the third LVDS driver D3 and the third LVDS receiver R3, and two load resistors R TThe first LVDS driver D1 and the first LVDS receiver R1, the second LVDS driver D2 and the second LVDS receiver R2, and the third LVDS driver D3 and the third LVDS receiver R3 all transmit data through the same transmission. In this way, data transmission between multiple displays can be achieved through a single channel, reducing the cost of the equipment, and realizing screen interaction between multiple displays, thereby improving the entertainment during riding or driving.

[0077] In some embodiments, Figure 5 As shown, the system may further include a controller 140; the controller 140 is connected to the instrument display 110 and the multimedia display 120 respectively;

[0078] The controller 140 is used to generate a first control instruction according to the first touch operation; the first control instruction is used to trigger the half-duplex LVDS transmission channel to send the first display data to the multimedia display; or to generate a second control instruction according to the second touch operation; the second control instruction is used to trigger the half-duplex LVDS transmission channel to send the second display data to the instrument display. In this way, the transmission channel can be controlled by the controller to perform data transmission in time periods, thereby realizing bidirectional transmission of display data.

[0079] In some embodiments, the first touch operation may include a touch sliding operation; the controller is used to determine a sliding direction of the touch sliding operation in response to the touch sliding operation of the user; according to the sliding direction, determine a display corresponding to the sliding direction from a preset trajectory correspondence relationship, and use the display corresponding to the sliding direction as the multimedia display; the preset trajectory correspondence relationship includes a correspondence between the sliding direction and the display.

[0080] For example, there is a one-to-one correspondence between the sliding direction and the display. When the sliding direction is determined according to the touch sliding operation, and when it is determined that the display corresponding to the sliding direction is a multimedia display, the first display data is sent to the multimedia display through a half-duplex LVDS transmission channel. In this way, the display to which the display data is to be transmitted can be determined according to the preset track correspondence, which facilitates the user to quickly send the display data to the corresponding display, thereby improving the transmission efficiency.

[0081] In other embodiments, the second touch operation may also include a touch sliding operation, and the controller is used to determine a sliding direction of the touch sliding operation in response to the touch sliding operation of the user; according to the sliding direction, determine a display corresponding to the sliding direction from a preset trajectory correspondence relationship, and use the display corresponding to the sliding direction as the instrument display.

[0082] For example, when the sliding direction is determined according to the touch sliding operation, and the display corresponding to the sliding direction is determined to be an instrument display, the second display data is sent to the corresponding instrument display through a half-duplex LVDS transmission channel. In this way, data can be quickly transmitted through the touch operation, thereby improving the transmission efficiency of the display data.

[0083] It is understandable that, when the multimedia display includes multiple displays, the first display data of the instrument display can be sent to the corresponding display through the transmission channel in response to the user's touch operation on the instrument display; the display data of the first display can also be sent to the corresponding second display through the transmission channel in response to the user's touch operation on the first display. Data can be transmitted between the above multiple displays through the transmission channel, and the transmission method is the same as the transmission process of the above display data, which will not be repeated here. In this way, the mutual transmission of display data between multiple displays in the vehicle cabin can be realized, which improves the interactivity and entertainment of the vehicle display system.

[0084] In some embodiments, Figure 6 As shown, the system may further include a target button 150; the target button 150 may be installed on the steering wheel or the central control device of the vehicle; the target button 150 is connected to the controller 140; the first touch operation includes a triggering operation on the target button;

[0085] The controller 140 is further configured to determine the display corresponding to the target button in response to the user's triggering operation on the target button, and use the display corresponding to the target button as the multimedia display; the target button corresponds to the display in a one-to-one manner.

[0086] For example, the target button can be a multi-function button corresponding to the instrument display and the multimedia display. The target button can also be multiple independent buttons corresponding to the instrument display and the multimedia display respectively. In the case where there are multiple multimedia displays, each independent button corresponds to each multimedia display respectively. The trigger operation can be a pressing operation, a rotating operation or a touching operation, etc., which is not limited here. In this way, the data transmission between multiple displays can be controlled by the target button, which is convenient for user operation and improves the efficiency of data transmission.

[0087] In other embodiments, the second touch operation may also include a trigger operation on the target button; the controller is further configured to determine the display corresponding to the target button in response to the user's trigger operation on the target button, and use the display corresponding to the target button as the instrument display. In this way, the controller can trigger the half-duplex LVDS transmission channel to transmit the second display data to the instrument display through the touch operation on the target button.

[0088] In some embodiments, Figure 7 As shown, the system may further include a terminal 160, which is connected to the instrument display 110 and the multimedia display 120 respectively; the terminal 160 is used to send the third display data of the terminal to the instrument display or the multimedia display in response to the user's third touch operation. The instrument display or the multimedia display is also used to display the third display data.

[0089] For example, the terminal may include a mobile phone, a tablet or a laptop, etc., and the third display data may include picture information, navigation information or video information, etc., which are not limited here. The terminal may be connected to the instrument display and the multimedia display respectively by wireless connection or wired connection; for example, the wireless connection method may be Bluetooth, 4G or 5G, etc., and the wired connection method may be connected through a USB interface, etc. In this way, interaction and data transmission between the terminal and the display in the vehicle cockpit can be realized, thereby improving the user experience.

[0090] In other embodiments, the controller may also send the fifth display data to the multimedia display through the half-duplex LVDS transmission channel when the instrument display displays the fourth display data, so that the multimedia display displays the fifth display data.

[0091] For example, when the vehicle is started and the instrument display and the multimedia display enter a display state, the controller may control the instrument display to display the fourth display data, and control the multimedia display to display the fifth display data.

[0092] For example, the display data may be an animation, which may be set by the user according to usage conditions and is not limited here. For example, the fourth display data may be an animation of the rising sun, so that the main interface of the instrument display may be highlighted after the instrument display screen lights up; the fifth display data may be an animation of the vehicle driving on a road, and the background screen displays the changing of seasons, and the road may be a mountain road, a desert road, or a city road, etc. Since it takes a long time for the multimedia display to enter the display state from a black screen during the vehicle startup process, which reduces the user experience, the controller may send the fifth display data to the multimedia display through a half-duplex LVDS transmission channel, so that the multimedia display may simultaneously display the display data while entering the display state from a black screen, thereby improving the user experience.

[0093] Figure 8 A flow chart of a method for controlling a display is shown according to an exemplary embodiment. Figure 8As shown, the method is applied to a display control system, the system comprising an instrument display, a multimedia display and a half-duplex LVDS transmission channel; the method may include:

[0095] S202 . In response to the user's second touch operation on the multimedia display, send second display data of the multimedia display to the instrument display via the half-duplex LVDS transmission channel.
