Reconfigurable LED display screen and display method

A display method, wherein the display method is applied to a reconfigurable LED display screen, the reconfigurable LED display screen comprises at least one independent LED display unit;

• the LED display unit comprises a control terminal, a main signal line and a plurality of expandable LED light strings, each LED light string comprises a repeater device arranged at a head part and LED light-emitting elements sequentially connected in series with the repeater device, and two adjacent LED light-emitting elements in the LED light string are detachably connected in series, so as to change the LED light-emitting elements connected in series in the LED light string;
• the control terminal and the repeater devices in the plurality of LED light strings are sequentially connected in series to the main signal line, and two adjacent repeater devices on the main signal line are detachably connected in series, so as to change the repeater devices connected in series to the main signal line;
• and the display method comprises:
• transmitting, by the control terminal, a control signal sequence currently configured for an LED display unit where the control terminal is located to a repeater device connected in series with the control terminal, wherein the control signal sequence comprises control signals of LED light-emitting elements in the LED display unit where the control terminal is located, and an arrangement order of the control signals is determined based on an arrangement order of the repeater devices in the LED display unit and an arrangement order of the LED light-emitting elements in the LED light string;
• after the repeater device receives the control signal sequence, retaining first first-LED-count control signals according to first-LED-count configured currently, controlling an LED light string where the repeater device is located by using the retained control signals, and forwarding remaining control signal sequences to a next repeater device, wherein the first-LED-count configured in the repeater device is the number of LED light-emitting elements connected in series in the LED light string where the repeater device is located, wherein the LED display unit further comprises a plurality of branch signal lines, and each repeater device on the main signal line is detachably connected to different branch signal lines;
• repeater devices in some LED light strings in the LED display screen are connected in series to the main signal line, and for remaining LED light strings, a repeater device in at least one of the remaining LED light strings is connected in series to each branch signal line;
• and two adjacent repeater devices on the branch signal line are detachably connected in series, so as to change the repeater devices connected in series to the branch signal line.
