Embodiment Construction
[0033] The present invention provides a signal source switching method and device based on a dual-channel display device. In order to make the purpose, technical solution and advantages of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0034] see figure 1 , figure 1 It is a flowchart of a preferred embodiment of a method for switching sources based on a dual-channel display device provided by the present invention. As shown in the figure, the method includes the following steps:
[0035] Step S100, receiving a signal source switching instruction from a user;
[0036] Step S200, copy the current information source on the first channel to the second channel to form a copy of the source, set the display screen...

The invention discloses a dual-channel display equipment-based signal source switching method and a dual-channel display equipment-based signal source switching device. The method comprises the following steps of receiving a signal source switching instruction from a user; copying a current signal source on a first channel to a second channel to form a signal source copy, displaying a display picture corresponding to the signal source copy on the second channel in front, and disabling the display of the first channel; switching the current signal source on the first channel to a target signal source; displaying a display picture corresponding to the target signal source on the first channel, and gradually improving the transparency of the display picture of the signal source copy on the second channel until the display picture of the signal source copy on the second channel is completely transparent. Therefore, the signal sources are seamlessly switched, the phenomena of blue screen (black screen) and screen unsmoothness in a signal source switching process are prevented, the display pictures are smooth, and great convenience is brought to a user.
Description
technical field [0001] The present invention relates to the field of displays, in particular to a method and device for switching sources based on a dual-channel display device. Background technique [0002] With the increasingly high requirements for commercial display equipment, the seamless switching of signal sources plays an increasingly important role. There are two main types of traditional source switching: the first one is to directly switch the current source to the target source, which will cause a blue screen or black screen during source switching. This will cause a strong screen switching effect, which will cause a strong contrast impact on the human eye, which is not conducive to protecting the human eye. The second method is to lock the screen display during source switching, disable the screen, and then switch sources. However, there will be unsmooth display situations such as picture freezes and stops, so the existing source switching methods cannot be se...
