DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a display device whose video quality is enhanced while eliminating unstable elements at the time of transmitting a video signal. SOLUTION: The full-color video signal 3 outputted from an AV equipment 2 is converted into a digital serial signal 5 by a digital signal converter→4 in a transmitting part 1 and this signal 5 is made to have a transmission configuration to be transmitted till the LED control part 7 being in an LED video display device 6. There is an LED controller 8 in the control part 7 and the controller 8 has a digital interface receiving the signal 5 and it converts the signal 5 into an LED driving signal 9 driving respective LED display modules 11 and outputs the LED driving signal. Then, the LED display modules 11 obtain chrominance information from the signal 9 which is outputted from the controller 8 to perform a full-color reproduction by controlling LEDs with pulses.
