The high-definition full-color LED display screen used in the conference system according to claim 4, wherein: the lower terminal surface of circuit board (18) is provided with conductive contact a (17), the up end of sliding support (20) is provided with conductive contact b (19) that corresponds from top to bottom with conductive contact a (17), conductive contact b (19) pass through the wire with drying blower (24) and are connected, conductive contact a (17) pass through circuit board (18) and external power electric connection.
8. A method for using a high-definition full-color LED display screen used in a conference system, the high-definition full-color LED display screen used in the conference system according to any one of claims 1 to 7, characterized in that: the method comprises the following steps:
s1: the high-definition display screen (1) is lifted, a motor (6) is started through external control equipment, a first driving bevel gear (7) on a driving rotating rod (8) and a first driven bevel gear (5) at the lower end of a first driven rotating rod (3) are engaged, so that the first driven rotating rod (3) starts to rotate, and a containing box (12) is lifted vertically upwards due to the threaded relation between the first driven rotating rod (3) and a threaded sleeve (2), so that the normal playing requirement is met;
S2: liquid is fed into the cleaning friction roller (15), the cleaning liquid stored in the cleaning friction roller is conveyed to the atomizing spray head through the liquid conveying pipe by pressing the pressing rod on the manual liquid feeding pump, and is atomized by the atomizing spray head and then uniformly sprayed to the cleaning friction roller (15), so that the cleaning friction roller (15) is kept in a wet state;
s3: the high-definition display screen (1) is recovered and cleaned, a motor (6) is started through an external control device, a driving rotating rod (8) starts to rotate through the reverse rotation of the motor (6), so that the high-definition display screen (1) starts to move downwards, meanwhile, due to the meshing action of a second driving bevel gear (9) on the driving rotating rod (8) and a second driven bevel gear a (10) at the lower end of a second driven rotating rod (4), the second driven rotating rod (4) synchronously rotates, and due to the meshing action of a second driven bevel gear b (13) at the upper end of the second driven rotating rod (4) and a third driven bevel gear (14) on a cleaning friction roller (15), a wet cleaning friction roller (15) starts to rotate to perform friction cleaning treatment on the high-definition display screen (1);
s4: drying process after high definition display screen (1) is clean, in the in-process that continuously descends when high definition display screen (1), sliding bracket (20) receive the extrusion of high definition display screen (1) and shrink, make the electrically conductive contact b (19) of sliding bracket (20) up end and electrically conductive contact a (17) contact on circuit board (18) lower terminal surface and make the circuit circulate, thereby make drying blower (24) begin to work, dry processing to high definition display screen (1) after the moist wiping, receive and release back in containing box (12) completely when high definition display screen (1), sliding bracket (20) break away from high definition display screen (1) thereby do not receive the extrusion, make the interconnecting link disconnection of drying blower (24) and stop drying work.
