20090289818 | CAPACITIVE KEYBOARD DEVICE WITH A KEYSTROKE TRIGGERING THRESHOLD ADAPTIVELY ADJUSTABLE CAPABILITY - A capacitive keyboard device with a keystroke triggering threshold adaptively adjustable capability is proposed, which is designed for integration to an electronic unit, such as PDA (Personal Digital Assistant) computers, mobile phone unit, and calculator, for use as a data input device for the electronic unit. The proposed capacitive keyboard device is characterized by the operation of a triggering threshold adaptive adjustment function that can adaptively adjust the keystroke triggering threshold of the capacitive keyboard device in response to the user's habitual key-pressing action during each use, which also takes account of all internal factors (such as decay of the capacitor structure) and external factors (such as physical characteristics of the user's fingers). This feature allows the capacitive keyboard device to be reliable in operation for long period of use. | 11-26-2009 |

20100007626 | Touch signal transmission circuit for touch LCD - A touch signal transmission circuit for a touch control LCD is mounted to an inner side of an upper substrate of the LCD, having a first patterned electrode layer and a second patterned electrode layer, which are electrically insulated from each other and partially overlap each other in intervals to define a touch control section. Each of the first and second patterned electrode layers includes a plurality of electrodes in the shape of footsteps. The electrodes are interlaced with one another, having some parts overlapping and right corresponding to each other to define a plurality of touch-sensitive points. In this way, only fewer footstep-shaped electrodes are needed to cover the whole touch control section to decrease the number of bonding pads and pins of a touch control IC. Besides, a lot of touch sensitive points are closely disposed in the touch control section to keep quick detection and decoding. | 01-14-2010 |
20100007627 | Touch signal transmission circuit and liquid crystal display using the same - A touch signal transmission circuit and an LCD using the same include an upper substrate and a plurality of first and second electrodes mounted at an inner side of the upper substrate. The first and second electrodes are arranged along a first direction and a second direction respectively, being electrically insulated with each other. Where the first and second electrodes are interlaced with each other defines touch0sensitive sections. When the user's finger touches the surface of the upper substrate, the touch-sensitive sections are touched for control or activation of the LCD. In light of this structure, the whole LCD is thinned and lightened. | 01-14-2010 |
20100033436 | Touch-Controlled Liquid Crystal Display and Touch Panel thereof - A touch-controlled LCD includes a liquid crystal display panel and a touch panel. The liquid crystal display panel includes a first substrate, a second substrate and a liquid crystal layer disposed between the first substrate and the second substrate. The touch panel is disposed on a side of the second substrate facing away from the liquid crystal layer.
