Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative labor.

[0043] As mentioned above, in traditional solutions, when using a MIPI screen to display the image corresponding to the input signal emitted by the signal source, abnormal phenomena such as screen distortion and screen flickering often occur, seriously affecting the display quality of the image on the MIPI screen.

[0044] Research has found that the poor display quality of MIPI screens in traditional solutions is mainly due to two major factors: first, MIPI screens are only compatible with specific fixed resolutions. Once the signal resolution output by the signal source is different from it, the screen is prone to display problems such as distorted screen and flickering screen; second, the interface bandwidth adapted to the MIPI screen is difficult to carry high-speed MIPI communication. When the input signal bandwidth is too high, signal transmission is prone to large-scale packet loss, which will also cause problems such as distorted screen and flickering screen.

[0045] Based on the above reasons, the present application discloses a data processing method applied to a target system, comprising: obtaining display feature data of an input signal emitted by a signal source through a target bridge chip; determining whether the display feature data matches reference feature data through the target bridge chip; if the display feature data does not match the reference feature data, processing the display feature data through the target bridge chip to obtain target feature data that matches the reference feature data. The display feature data of the input signal emitted by the signal source is processed through the bridge chip so that the processed display feature data matches the reference feature data of the MIPI screen, thereby optimizing the display effect of the input signal on the MIPI screen and ensuring high-quality image presentation.

[0046] In order to help those skilled in the art better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0047] Figure 1 A schematic diagram of the structure of a target system provided in an embodiment of the present application. Figure 1 As shown, the target system 100 disclosed in this application includes a signal source 101 , a target bridge chip 102 and a MIPI screen 103 .

[0048] It should be noted that the signal source mentioned in the subsequent embodiments of this application corresponds to the signal source 101 , the target bridge chip corresponds to the target bridge chip 102 , and the MIPI screen corresponds to the MIPI screen 103 .

[0049] The signal source establishes a connection with the target bridge chip through the high-speed signal receiving end, and the MIPI screen establishes a connection with the target bridge chip through a connecting line.

[0050] Figure 1 The data flow process of the target system is as follows: the input signal sent by the signal source is transmitted to the target bridge chip through the high-speed signal receiving end; the target bridge chip processes the input signal and transmits the processed input signal to the MIPI screen through the connecting line; after receiving the processed input signal, the MIPI screen displays the processed input signal.

[0051] Figure 2 A flowchart of a data processing method provided in an embodiment of the present application. Figure 2 As shown, the data processing method disclosed in this application includes:

[0052] S201: Acquire display characteristic data of the input signal sent by the signal source through the target bridge chip.

[0053] The display characteristic data is data that affects the display quality of the picture corresponding to the input signal. The display characteristic data in this application includes at least the bandwidth occupied by the input signal and may also include the resolution of the input signal.

[0054] S202: Determine, by the target bridge chip, whether the display feature data matches reference feature data.

[0055] The reference feature data is data that affects the quality of the image displayed on the MIPI screen. The reference feature data in this application includes at least the screen interface bandwidth of the MIPI screen and may also include the resolution supported by the MIPI screen.

[0056] Among them, the screen interface bandwidth of the MIPI screen refers to the bandwidth corresponding to the connection line between the target bridge chip and the MIPI screen.

[0057] The meaning of this step is to determine whether the display characteristic data matches the reference characteristic data through the bridge chip.

[0058] It is understood that if the display characteristic data is the bandwidth occupied by the input signal, the reference characteristic data is the screen interface bandwidth of the MIPI screen; if the display characteristic data is the resolution of the input signal, the interface characteristic data is the resolution supported by the MIPI screen. In other words, the premise for determining whether the display characteristic data matches the reference characteristic data is that the data type of the display characteristic data corresponds to the data type of the reference characteristic data.

[0059] S203 : If the display feature data does not match the reference feature data, the display feature data is processed by the target bridge chip to obtain target feature data that matches the reference feature data.

[0060] In an optional implementation, the display characteristic data is the bandwidth occupancy of the input signal, and the reference characteristic data is the screen interface bandwidth of the MIPI screen.

[0061] In this case, after obtaining the display characteristic data of the input signal and the reference characteristic data of the MIPI screen through the target bridge chip, if the target bridge chip determines that the bandwidth occupancy of the input signal is greater than the screen interface bandwidth of the MIPI screen (that is, the bandwidth occupancy of the input signal does not match the screen interface bandwidth), the target bridge chip compresses the bandwidth occupancy of the input signal to the target bandwidth occupancy; wherein the target bandwidth occupancy is less than or equal to the MIPI screen interface bandwidth.

[0062] It can be understood that when the bandwidth occupancy of the input signal is compressed to less than or equal to the MIPI screen interface bandwidth, the phenomenon of data packet loss during signal transmission will be greatly reduced, and the display effect of the picture corresponding to the input signal on the MIPI screen can be optimized, so that the picture corresponding to the input signal can be displayed on the MIPI screen with high quality.

[0063] For example, after the signal source sends an input signal, the bandwidth occupancy of the input signal can be recorded by PCR (Pixel Clock Recover) in the target bridge chip, and the input signal can be error detected by the target bridge chip to ensure that there is no abnormality in the input signal.

[0064] For example, after the target bridge chip determines that the bandwidth occupied by the input signal is greater than the screen interface bandwidth of the MIPI screen, the target bridge chip can perform DSC compression (Display Stream Compression) to compress the bandwidth occupied by the input signal to the target bandwidth occupancy.

[0065] Exemplarily, the target bandwidth occupancy may be one third of the bandwidth occupancy of the input signal, that is, the bandwidth occupancy of the input signal is compressed to one third of the original bandwidth occupancy through the target bridge chip.

[0066] In an optional implementation, the display characteristic data includes the bandwidth occupancy of the input signal and the resolution of the input signal; the reference characteristic data includes the screen interface bandwidth of the MIPI screen and the resolution supported by the MIPI screen.

[0067] In this case, after obtaining the display feature data of the input signal and the reference feature data of the MIPI screen through the target bridge chip, the target bridge chip determines whether the bandwidth occupied by the input signal is greater than the screen interface bandwidth of the MIPI screen, and determines whether the resolution of the input signal is equal to the resolution supported by the MIPI screen.

[0068] If it is determined that the bandwidth occupancy of the input signal is greater than the screen interface bandwidth, and the resolution of the input signal is different from the resolution supported by the MIPI screen, the bandwidth occupancy of the input signal is compressed to the target bandwidth occupancy through the target bridge chip, and the resolution of the input signal is scaled to the target resolution through the target bridge chip.

[0069] If it is determined that the bandwidth occupied by the input signal is greater than the screen interface bandwidth, and the resolution of the input signal is the same as the resolution supported by the MIPI screen, the bandwidth occupied by the input signal is compressed to the target bandwidth occupancy through the target bridge chip.

[0070] If it is determined that the bandwidth occupied by the input signal is not greater than the screen interface bandwidth, and the resolution of the input signal is different from the resolution supported by the MIPI screen, the resolution of the input signal is scaled to the target resolution through the target bridge chip.

[0071] It should be noted that the specific operations of determining the resolution of the input signal, determining the bandwidth occupancy of the input signal, compressing the bandwidth occupancy of the input signal, and scaling the resolution of the input signal are described in the aforementioned embodiments and will not be repeated here.

[0072] In summary, when the signal source changes the resolution of the input signal, the method disclosed in this application can perceive the resolution change in real time, and dynamically scale the picture through the image scaler or image scaling chip to ensure the continuity and consistency of the output signal; when the bandwidth occupancy of the input signal sent by the signal source exceeds the bandwidth of the MIPI screen interface, the method disclosed in this application can automatically adjust the bandwidth occupancy of the input signal to ensure the normal display of the output signal, greatly improving the screen's adaptability to signals of different bandwidths. Furthermore, the method disclosed in this application adopts a switching mechanism based on dynamic detection of the input signal state, which significantly shortens the response time, can achieve millisecond-level signal switching, effectively avoid the black screen phenomenon, and significantly improve the user experience.
