The invention relates to a signal window opening method and system. The method comprises the steps of obtaining signal response durations of display units of a spliced wall, wherein the signal response durations are time lengths between time of sending signal window opening instructions and time of finishing signal window opening by the display units; according to the signal response durations, obtaining target delay durations of the display units, wherein the target delay durations are used for controlling the display units to synchronously finish the signal window opening; and according to the values of the target delay durations, sending the signal window opening instructions to the corresponding display units in sequence. According to the method, the situation that the signal responsedurations of the display units have difference is considered; the target delay durations of the display units are obtained according to the signal response durations; and the signal window opening instructions are sent to the corresponding display units in sequence according to the values of the target delay durations, so that the display units can synchronously finish the signal window opening, and the visual effect of a user is improved.
Description
technical field [0001] The present application relates to the technical field of splicing display, in particular to a signal window opening method and a signal window opening system. Background technique [0002] At present, with the continuous deepening of the application of splicing technology, the scale of digital video wall systems is getting larger and larger, especially for some super large systems, the general scale is more than 100 display units, or even more. [0003] The method of opening the signal window commonly used in the current large splicing wall system is: the control host sends instructions to open the signal window to the display unit one by one, and then forms a whole picture of the splicing wall. At present, the synchronization signal is used to control the synchronization of the signal window on the hardware. Open. However, when some display units on the system are aging, the aging display unit responds slowly after receiving instructions, and the re...
