Abstract

The embodiment of the invention discloses a multi-screen display method and device. The method comprises: generating multiple screen pictures by an AP chip, and if the difference value of the resolution height or the resolution width of any two screen pictures in the multiple screen pictures is larger than a preset difference value, adjusting the resolution width of the plurality of screen pictures to a first resolution width and / or adjusting the resolution height of the plurality of screen pictures to a first resolution height to obtain a plurality of intermediate pictures; and splicing the plurality of intermediate pictures to obtain a target picture. By adjusting the resolution widths and / or resolution heights of the plurality of screen pictures to the same value, the problem of screen flash caused by non-uniform refreshing due to excessive continuous blanking of a certain display screen due to different resolution widths of the plurality of screens can be effectively solved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a multi-screen display method and device. Background technique [0002] With the vigorous development of display technology, the demand for dual-screen different display functions in consumer, financial payment, and commercial display markets is increasing. At present, the screen output of most application chips (Application Processor, AP) is usually a single mobile industry processor interface (Mobile Industry Processor Interface, MIPI) display serial interface (DisplaySerial Interface, DSI) interface, which can only be connected to a single MIPI display Screen. Because the MIPI DSI output bandwidth of the single-channel MIPI DSI AP chip is designed according to the bandwidth requirements of connecting a single display screen. Therefore, when the resolution widths and / or resolution heights of the multiple connected display screens are different, the proble...
