FLAT PANEL DISPLAY WITH CHARACTERISTIC OF LOW POWER CONSUMPTION

摘要

PURPOSE: A flat panel display with a characteristic of low power consumption is provided to prevent an increase of power consumption and EMI(Electro Magnetic Interference) due to extreme changes of digital image data patterns. CONSTITUTION: An input conversion circuit(110) is formed with input logic circuits(112A,112B,112C) and input logic circuits(114C,114A,114B). The input conversion circuit(110) is used for converting the first digital image data pattern to the second digital image pattern. An input selection circuit(120) is formed with 2x1 multiplexers(122). Selection terminals(S) of the 2x1 multiplexers(122) are connected commonly with switch selection signals of a timing control portion. A signal processing circuit(130) is used for processing R, G, and B image data received from the input conversion circuit(110) and the input selection circuit(120). An output conversion circuit(140) is used for converting the second digital image data pattern to the first digital image data pattern. An output selection circuit(150) is formed with 2x1 multiplexers(152,154,156).
