  • Publication number: 20110175944
    Abstract: A control system is used for maintaining color of a display device, wherein the color is g formed by brightness of a first, second and a third color elements. The first, second and the third color elements have a first brightness, second brightness and a third brightness respectively and a luminance ratio of the first brightness, second brightness and the third brightness. The control system comprises a light-detecting member, a processing unit and a light source driver. The light-detecting member is used for detecting brightness of the first, second and the third color elements.

  • Publication number: 20110151655
    Abstract: The present disclosure provides various methods of fabricating a semiconductor device. A method of fabricating a semiconductor device includes providing a semiconductor substrate and forming a gate structure over the substrate. The gate structure includes a first spacer and a second spacer formed apart from the first spacer. The gate structure also includes a dummy gate formed between the first and second spacers. The method also includes removing a portion of the dummy gate from the gate structure thereby forming a partial trench. Additionally, the method includes removing a portion of the first spacer and a portion of the second spacer adjacent the partial trench thereby forming a widened portion of the partial trench. In addition, the method includes removing a remaining portion of the dummy gate from the gate structure thereby forming a full trench. A high k film and a metal gate are formed in the full trench.

  • Publication number: 20100262849
    Abstract: A power-saving electronic device for use with a computer motherboard in a “suspend to memory” state is disclosed. The power-saving electronic device enables compulsory interruption of power supply to a south bridge chip and a super input output (SIO) chip of the computer motherboard in the “suspend to memory” state, such as an S3 state of Advanced Configuration and Power Interface (ACPI), so as to save power. After a user presses a power switch, the power-saving electronic device enables the south bridge chip and SIO chip to be powered on by a standby power supplied thereto and enables the computer motherboard to remain capable of awakening and resuming from the S3 state.
