For example, the first display interface may be a Digital Video Output (DVO) interface, the first image signal is a DVO signal matching the DVO interface, and the bridge chip 10 sends the DVO signal to the conversion module 20 through the DVO interface. The display interface of the display screen 30 is a second display interface, the conversion module 20 is further provided with a second display interface, the conversion module 20 and the display screen 30 are connected through the second display interface, and the second display interface is used for transmitting a second image signal matched with the second display interface. For example, the second Display interface may be an Embedded Display interface (EDP) or a Low-voltage differential Signaling (LVDS) interface, the second image signal is an EDP signal matched with the EDP interface or the second image signal is an LVDS signal matched with the LVDS interface, and the conversion module 20 sends the second image signal to the Display screen 30 through the second Display interface.

For example, the image data indicated by the image processing instruction is the picture data stored in the preset video memory location, and the bridge piece 10 may read the picture data from the preset video memory location, and generate the first image signal according to the picture data through the GPU. After the bridge piece 10 generates the first image signal, the first image signal may be sent to the conversion module 20 by using the first display interface. In combination with the above example, if the first display interface is a DVO interface, the bridge chip 10 may generate a DVO signal (a first image signal) according to the picture data through the GPU, and send the DVO signal to the conversion module 20 through the DVO interface. The process of obtaining the image data by the bridge chip 10 and generating the first image signal by the GPU and the process of sending the first image signal to the conversion module 20 refer to the related art, which is not limited in this embodiment.

Referring to fig. 2, another display device according to a first embodiment of the present invention is shown.
In this embodiment, the bridge piece 10 is further configured to receive the display parameters sent by the conversion module 20, generate configuration parameters according to the display parameters, and send the configuration parameters to the conversion module 20.
The conversion module 20 is further configured to obtain the display parameters from the display screen 30, and adjust the output configuration of the conversion module 20 according to the configuration parameters.
The display parameter may be, for example, identification information corresponding to parameters such as resolution and screen refresh frequency of the display screen 30, and the identification information is used to identify an image signal displayable by the display screen 30. The GPU integrated in the bridge piece 10 may generate configuration parameters that may be received by the interface of the conversion module 20 according to the display parameters, and the conversion module 20 may adjust the output configuration according to the configuration parameters. In the process of displaying images, the bridge chip 10 may generate and output a first image signal corresponding to the display parameter according to the image data, and the conversion module 20 may convert the first image signal into a second image signal corresponding to the display parameter according to the adjusted output configuration, so that the display screen 30 may output images according to the receivable second image signal.
For example, the display parameter may optionally include Extended Display Identification Data (EDID). Referring to fig. 3, which shows another display device according to the first embodiment of the present invention, the bridge piece 10 may be a bridge piece 7a1000, and the display screen 30 may be an LCD (Liquid crystal display). After the display device is powered on, the conversion module may read the EDID data from the display screen 30 through the EDP interface (second display interface), use the EDID data as a display parameter, and store the EDID data. The bridge chip 7a1000 may send a read instruction to the conversion module, and the conversion module, after receiving the read instruction, sends the prestored EDID data to the bridge chip 7a 1000. Taking the first identification information corresponding to the image resolution supported by the display screen 30 and included in the EDID data as an example, after the bridge chip 7a1000 acquires the EDID data, it may analyze the EDID data, and if the first identification information corresponding to the image resolution supported by the display screen 30 and included in the EDID data is "AF", the first identification information "AF" identifies that the display screen 30 may support an image signal with a resolution of 1920 × 1080. The GPU integrated in the bridge chip 7a1000 may generate second identification information (configuration parameter) corresponding to a resolution of 1920 × 1080, the second identification information being "0H", for example. The bridge chip 10 may perform a write operation on the conversion module 20, and send the second identification information "0H" to the conversion module 20, and the conversion module 20 may receive and store the second identification information "0H" in the register corresponding to the resolution, so as to implement adjustment of the output configuration. The second identification information "0H" in the register is used to control the conversion module 20 to convert the first image signal into an image signal with a resolution of 1920 × 1080 corresponding to the second identification information "0H". After the conversion module 20 adjusts the output configuration, the bridge chip 7a1000 may acquire the image data, generate a first image signal with a resolution of 1920 × 1080 from the image data, and transmit the first image signal to the conversion module 20, and the conversion module 20 may convert the first image signal into a second image signal with a resolution of 1920 × 1080, and transmit the second image signal to the display 30. The display 30 can display an image according to the second image signal having a resolution of 1920 × 1080. The process of the conversion module acquiring the display parameters from the display screen, the process of the bridge piece acquiring the display parameters from the conversion module, and the process of the conversion module adjusting the output configuration according to the configuration parameters refer to the prior art, which is not limited in this embodiment.
It should be noted that, in practical application, the display parameters may further include first identification information corresponding to parameters such as a screen refresh frequency, a pixel clock signal frequency, a line synchronization pulse frequency, and a field synchronization pulse frequency of the display screen. Correspondingly, the bridge chip can combine parameters such as resolution of the display screen, screen refreshing frequency, pixel clock signal frequency, line synchronization pulse frequency and field synchronization pulse frequency to generate corresponding configuration parameters. For example, in combination with the above example, the bridge slice may generate the second identification information corresponding to the resolution 1920 × 1080, generate the second identification information corresponding to the screen refresh frequency 60Hz according to the screen refresh frequency (for example, 60Hz) corresponding to the resolution 1920 × 1080 included in the display parameters, send the second identification information corresponding to the resolution 1920 × 1080 and the screen refresh frequency 60Hz respectively to the conversion module, adjust the output configuration of the conversion module according to the second identification information corresponding to the resolution 1920 × 1080 and the second identification information corresponding to the screen refresh frequency 60Hz, and enable the conversion module to output the second image signal with the resolution 1920 × 1080 and the screen refresh frequency 60 Hz.
Meanwhile, the bridge chip can set configuration parameters according to the hardware characteristics of the conversion module. In combination with the above example, the bridge slice may set the configuration parameters such that the resolution corresponding to the configuration parameters is not greater than twice 1920 × 1080 and not less than half 1920 × 1080. The process of setting configuration parameters by the bridge chip according to the hardware characteristics of the conversion module refers to the related art, which is not limited in this embodiment.
In this embodiment, before the image is output, the bridge chip may obtain the display parameters of the display screen through the conversion module, and generate the configuration parameters corresponding to the display parameters according to the display parameters, and the conversion module may adjust the output configuration according to the configuration parameters. In the image output process, the bridge chip can output a first image signal corresponding to the display parameter, the conversion module can convert the first image signal into a second image signal corresponding to the display parameter according to the adjusted output configuration, so that the second image signal matched with the display screen can be obtained, the output second image signal can be matched with the display screen, and the type of the display screen in the display device can be flexibly selected.
