Abstract: 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. The touch panel includes a plurality of first electrodes being parallel to each other, a plate shaped second electrodes facing the first electrodes, and a plurality of spacers disposed between the first electrodes and the second electrode.

Abstract: 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.

Abstract: A touch detecting circuit of the present invention is provided between a substrate and a bistable display film of a display. The touch detecting circuit includes a plurality of first electrodes along a first direction, a plurality of second electrodes along a second direction, and an insulating layer between the first electrodes and the second electrodes. The insulating layer has through holes, on opposite ends of which the first electrodes and the second electrodes are provided. Each of the second electrodes has a contact terminal not masking the entire through hole. The first electrodes will contact the second electrodes under an external force exertion and a resistance effect will occur to let the system terminal of the display detecting the location of the external force.

Abstract: A liquid crystal display having a touch detecting structure includes an upper substrate, a lower substrate and a liquid crystal layer therebetween. A plurality of first electrodes, a plurality of second electrodes, and an insulating layer, which insulates the first and second electrodes, are provided between the liquid crystal layer and the lower substrate. The insulating layer is provided with a plurality of through holes associated with the first and second electrodes. An auxiliary pressing unit is between the upper substrate and the second electrodes, which includes a plurality of insulating protrusions above the through holes. When the liquid crystal display is pressed, the protrusion under the pressure will push the second electrode to have the second contact area contacting the first contact area that may increase the accuracy of touching.

Abstract: 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.

Abstract: A printed circuit board with ground grid includes a first insulating plate, a plurality of first metal lines formed on the first insulating plate, a sub-circuit board above the plurality of first metal lines, a second insulating plate above the sub-circuit board, a plurality of second metal lines formed on the second insulating plate, and, a plurality of conductive components formed in and through the second insulating plate and the sub-circuit board to electrically connect the plurality of first metal lines and the plurality of second metal lines. As additional electronic elements and circuits can be located on the first insulating plate and/or on the second insulating plate without limitation, difficulties for printed circuit board layout can be dramatically reduced.
