Mobile terminal, combined terminal device and method for splicing control

A splicable mobile terminal, a plurality of the mobile terminals being capable of being spliced to be combined into a single combined terminal device, wherein each of the mobile terminals can selectively operate as a master in a master operating state and operate as a slave in a slave operating state, each of the mobile terminals comprises a display screen and a splicing management module, which splicing management module comprises:

• a state determination unit configured to cause the mobile terminal to selectively enter the master operating state or the slave operating state according to a state determination instruction;
• a display partitioning unit configured to, when the mobile terminal operates as the master, partition the display content of the master according to the display screen resource of individual said mobile terminals in the combined terminal device, to obtain a plurality of pieces of partitioned display data corresponding to the plurality of the mobile terminals in the combined terminal device, and send corresponding said partitioned display data to the slaves;
• and
• a display switching unit configured to, in a case in which the mobile terminal acts as the slave, upon reception of the partitioned display data from the master, hide the current work task of the mobile terminal in the background for running, and display the received partitioned display data.
