  • Patent number: 7612772
    Abstract: A display monitor for a common display data channel uses a DDC access switch to separate the common display data channel, so that regardless of whether the display monitor is powered on or off, a personal computer can access the Extended Display Identification Data (EDID) in the EEPROM, and the low-level voltage of an MCU in the display monitor won't interfere in the access between the personal computer and the EEPROM. When the power of the display monitor is turned on, the DDC access switch closes so that the MCU can access the EDID in the EEPROM.

  • Patent number: 7508355
    Abstract: The present invention relates to a method applied on displays for recognizing video signal timing of analog input. The present invention employs the horizontal-synchronized-signal interrupt value to distinguish among its inputted video signal timing, allowing to recognize its pixel and correctly display its corresponding video signal timing even when the inputted signal timings share the same horizontal frequency, vertical frequency, and polarity. In case when the display is displaying incorrect video signal timing, the present invention also allows inputting a switch signal to adjust its display mode accordingly, enabling the display to show the correct resolution of the video signal timing under normal operation.

  • Patent number: 7420553
    Abstract: The invention discloses a control circuit and method thereof, which enable a display device to have low power consumption. The display device is able to switch between a normal mode and a standby mode, and reduce the power consumption of the display device under the standby mode. A synchro signal detection circuit, an infrared receiver, and a power switch are used to determine when to output a triggering signal. If an MCU inputs a triggering signal, a switch circuit will provide electricity for a peripheral circuit, then the display device switches to the normal mode; otherwise, the switch circuit will stop providing electricity for the peripheral circuit, and the display device switches to the standby mode.
