Multicolor LED casing structure for display screen of electronic device, has integrated circuit chip to deliver operating power through power output and control signal through clock output and serial data output

摘要

The structure has a connecting unit for connecting red, green and blue LED cubes (11, 12, 13) to an integrated circuit chip (30). The chip controls the LED cubes, after receiving the operating power from a power input (Vcc) and a control signal from a clock input (CLKI) and a serial data input (SDI). The chip delivers the operating power through a power output (Gnd) and a control signal through a clock output (CLKO) and a serial data output (SDO). The LED cubes are controlled by pulse-width modulation.
