[0020] See also Figure 1 The embodiment of the utility model provides a cuttable LED display screen 100, comprising a control interface 10, a plurality of bus drivers 20 and a plurality of integrated lamp driver IC circuits 30. The integrated lamp driver IC circuit 30 is connected to the bus driver 20, and the bus driver 20 is connected to the control interface 10. Specifically, the bus driver 20 is connected to the control interface 10 via a bidirectional two-wire synchronous serial bus, and the integrated lamp driver IC circuit 30 is connected to the bus driver 20 via a bidirectional two-wire synchronous serial bus.
[0021] The control interface 10 receives external video data and then sends it to the integrated lamp driver IC circuit 30 through the bus driver 20.

When the control interface has more bidirectional two-wire synchronous serial buses, more controllable integrated lamp driver IC circuit groups will be available. As long as the electrical connection of the bidirectional two-wire synchronous serial bus is not damaged, the lamp beads will not be affected by cutting.
[0023] The cuttable LED display screen provided by the embodiment of the utility model can cut any area around the LED display screen. For example, cutting the lamp-driven integrated driver IC circuit (IC0 area) will not affect the display of other lamp bead areas. Therefore, the LED display screen can be cut into various shapes such as circle, hexagon, etc. according to needs.
