  • Publication number: 20130114032
    Abstract: An array substrate, liquid crystal display for the same and manufacturing method thereof are described. The array substrate includes a substrate, a plurality of scan lines, a plurality of data lines, a plurality of contact pads, a passivation layer and transparent conducting layer. The substrate has a first display region, a second display region and a first non-display region. The contact pads are disposed in the first non-display region. The transparent conducting layer disposed in the passivation layer includes a first pixel electrode, a second pixel electrode and a plurality of comb electrode. The first pixel electrode and second pixel electrode are disposed in the first display region and the second display region wherein the widths of the first pixel electrodes either are equal to or approximate the widths of the second pixel electrodes. The comb electrodes are disposed in the first non-display region and connected to the contact pads.

  • Publication number: 20130087791
    Abstract: A display device and a fabrication method thereof are provided. The display device includes a first metal layer disposed on a display area and a peripheral area. An insulating layer covers the first metal layer. A patterned semiconductor layer is disposed on the insulating layer at the display area. A second metal layer is disposed on the patterned semiconductor layer and the insulating layer at the peripheral area. A transparent conductive layer directly covers the second metal layer. A protective layer completely covers the second metal layer, the patterned semiconductor layer and the transparent conductive layer. The protective layer includes a first portion, a second portion and a through hole, wherein the first portion has a height which is higher than a height of the second portion.

  • Patent number: 8258972
    Abstract: An electronic device and method to prevent falling of the electronic device include setting one or more alarm means, detecting an acceleration and a moving direction of the electronic device using the three-axis accelerometer, and detecting that the electronic device is in a falling state if the acceleration is larger or equal to the acceleration of gravity and the moving direction is in the gravitational direction. The electronic device and method further include activating one or more of the alarm means if the electronic device is in the falling state or if a clip connected with a strap of the electronic device is not in a tightened state.

  • Publication number: 20120219701
    Abstract: A method for fabricating a touch sensor structure is disclosed and has steps of forming a conductive layer on a substrate; forming a patterned bridging photo-resist layer on the conductive layer through a half-tone masking process that the bridging photo-resist layer partially covers the conductive layer and has a first portion and a relatively thinner second portion; removing a portion of the conductive layer which is not covered by the bridging photo-resist layer to pattern the conductive layer; and removing the second portion of the bridging photo-resist layer to form a bridging layer and the patterned conductive layer is partially exposed to be a conductive-wire layer. Hence the present invention reduce one masking process during forming conducting wires and bridge structures and provides better production efficiency.

  • Patent number: 7228408
    Abstract: A multi-mode operation system and method for computer systems is proposed. The system includes a storage device having first and second disk partitions, a mode controller and a master boot program. The master boot program checks the status of the mode controller. If the computer system is running in PC mode, the master boot program hides the second disk partition, boots from the first disk partition, and loads a complete version of an operating system therein, thereby enables the computer system to run in the PC mode. If the computer system is running in a sub-mode being defined as an entry of a multimedia mode class, such as a music playing mode or video playing mode, the master boot program activates the second disk partition, boots therefrom, and loads a refined version of the operating system therein, thereby enables the computer system to run in the selected sub-mode.
