Control circuit for displaying the same video simultaneously to two or more panels |
摘要 |
A display panel control circuit includes a voltage controlled oscillator (VCO) for outputting a clock signal, a first-panel horizontal system pulse generation section, a second-panel horizontal system pulse generation section, a vertical system pulse generation section which is commonly used among the first and second panels, a phase comparator, and a smoothing element. The first-panel horizontal system pulse generation section and the second-panel horizontal system pulse generation section respectively generate a reference signal of a first-panel horizontal system output group and a reference signal of a second-panel horizontal system output group from signal VCOCLK 1 output from the VCO. Thus, it is possible to simultaneously drive two different panels.
