Abstract:
A video display device having a power saving mode, said video display device being selectively operable in an ultra power saving mode, said video display device comprising:voltage output means for generating plural direct current voltages in response to an input alternating current voltage, said plural direct current voltages comprising a 5V output, a .+-.8V output, a .+-.12V output and a 200V output;a microcomputer for controlling said voltage output means by detecting inputs of a horizontal sync signal, a vertical sync signal and a key signal;a soft power key for generating said key signal in response to user activation of said soft power key; andsaid microcomputer causing said video display device to be operable in said ultra power saving mode by controlling said voltage output means to prevent said 5V output, said .+-.8V output, said .+-.12V output and said 200V output when said key signal is first detected, said microcomputer controlling said voltage output means to enable said 5V output, said .+-.8V output, said .+-.12V output and said 200V output when said key signal is detected a second time during said ultra power saving mode.
