Problems solved by technology

[0004] However, in the above method, two buffer modules need to be used at the same time, which is easily limited by hardware resources. When there is only one buffer module in the system, two different data cannot be saved at the same time.
If the data stored in the same buffer module is sent to two displays with different resolutions, there will be a mismatch between the display data and the display device, and the display data cannot be displayed normally, which will reduce the user experience

Embodiment 1

[0024] figure 1 A structural block diagram of a system for synchronously displaying display devices with different resolutions provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where display devices with different resolutions are used for synchronous display, and the system can implement display devices with different resolutions. The method to synchronize the display. see figure 1 , the system specifically includes: an X-sever module 110, a DDX module 120, a libdrm module 130, a DRM module 140, an image processing module 150, a first type display device 160 and a second type display device 170, wherein,

[0025] The image processing module 150 is connected with the DRM module 140, and is used for processing the data to be displayed according to the display device information sent by the received DRM module 140 and sending the processed data to the DRM module; the first type display device 160, and the DRM module 140 The connec...

Embodiment 2

[0035] In this embodiment, based on the foregoing embodiments, the DRM module 140 and the image processing module 150 are further optimized. Wherein, the DRM module 140 is specifically used for:

[0036] If the DRM module 140 determines according to the resolution parameters in the display device information that the horizontal resolution of the first type display device 160 is equal to the vertical resolution of the second type display device 170 and the vertical resolution of the first type display device 160 is equal to the The horizontal resolution of the display device 170 is equal, and the DRM module 140 sends the data processing instruction in the display device information to the image processing module 150; wherein, the data processing instruction is to rotate 90 degrees;

[0037] Correspondingly, the image processing module 150 is specifically used for:

[0038] The image processing module 150 rotates the data to be displayed by 90 degrees according to the received ...

Embodiment 3

[0042] In this embodiment, based on the foregoing embodiments, the DRM module 140 and the image processing module 150 are further optimized. Wherein, the DRM module 140 is specifically used for:

[0043] If the DRM module 140 determines according to the resolution parameters in the display device information that the horizontal resolution of the first type display device 160 is not equal to the vertical resolution of the second type display device 170 or the vertical resolution of the first type display device 160 is different from the second If the horizontal resolutions of the type display devices 170 are not equal, the DRM module 140 will send the ratio of the horizontal resolution and the ratio of the vertical resolution between the first type display device 160 and the second type display device 170 in the display device information to the image processing module 150 ;

[0044] Correspondingly, the image processing module 150 is specifically used for:

[0045] The image...

Abstract

The invention discloses a system and a method for synchronous display on display devices with different resolutions. The system comprises an X-sever module, a DDX module, a libdrm module, a DRM module, an image processing module, a first type display device and a second type display device, wherein the image processing module is connected with the DRM module and used for processing to-be-displayed data according to received display device information sent by the DRM module and sending the processed data to the DRM module; the first type display device is connected with the DRM module and used for displaying to-be-displayed data according to control of the DRM module; the second type display device is connected with the DRM module and used for displaying the processed data according to control of the DRM module. The to-be-displayed data are processed by the image processing module, so that the processed data are matched with resolutions of the second type display device, images or videos are synchronously displayed on different types of display devices without limitation by hardware resources, and the user experience is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular to a system and method for synchronously displaying display devices with different resolutions. Background technique [0002] With the continuous development of science and technology, more and more users have higher and higher demands on using multiple display devices for synchronous display of images or videos. [0003] In the prior art, when using display devices with different resolutions to display images or videos synchronously, first obtain the horizontal resolution and vertical resolution of the first type of display, save the display data to the first buffer module, and save it in the The data of the first buffer module is sent to the first type of display, and the first type of display displays, and then obtains the horizontal resolution and vertical resolution of the second type of display, and saves the data stored in the first buffer modul...
