Screen splicing method and spliced screen

Abstract

The invention provides a screen splicing method and a spliced screen. A group of first ultrasonic transmitters and a group of first ultrasonic receivers are arranged on the same side of the screen; asecond ultrasonic transmitter or a second ultrasonic receiver is further arranged on the same side; whether an adjacent object exists near the same side of the screen or not is determined through a first ultrasonic transmitter and a first ultrasonic receiver; if the adjacent object exists, an ultrasonic signal of which the frequency is f0 is transmitted through a second ultrasonic transmitter, andan image receiving mode or an image transmitting mode is started; or the ultrasonic signal with the frequency of f0 is received through the second ultrasonic receiver, and an image receiving mode oran image sending mode is started. According to the method and the spliced screen, screen recognition is achieved through the ultrasonic sensor, then the screen is spliced, even if the alignment positions of the two screens are not strict, the screen can be successfully spliced, and therefore the method and the spliced screen provided by the invention can accept a placement screen with a certain angle.

Description

technical field [0001] The present disclosure relates to screen splicing technology, in particular to a screen splicing method and a splicing screen. Background technique [0002] At present, there is a kind of splicing screen. The splicing screen can be independently used as a display unit, and multiple splicing screens can be spliced ​​together to form a larger display screen. [0003] In the prior art, multiple independent splicing screens are spliced ​​in the way of infrared pairing tubes. Specifically, a pair of infrared pairing tubes can be installed on both sides of the splicing screen. The A side Tx of the whole machine 1 sends the A code value, and the whole machine 2 The B-side Rx of the whole machine 2 receives the A code value, the B-side Tx of the whole machine 2 sends the B code value, and the A side of the whole machine 1 receives the B code value. If the whole machine receives the B code value, then there is a machine connected to the A side of the whole mac...
