Liquid crystal display having touch detecting structure
First Claim
1. A liquid crystal display having a touch detecting structure, comprising:
- an upper substrate;
a lower substrate;
a liquid crystal layer between said upper substrate and said lower substrate;
a plurality of first electrodes between said lower substrate and said liquid crystal layer and substantially extended along a first direction, wherein some of said first electrodes have at least a first contact area respectively;
an insulating layer, which is provided between said first electrodes and said liquid crystal layer, having a plurality of through holes associated with said first contact areas of said first electrodes respectively; and
a plurality of second electrodes, which is provided between said insulating layer and said liquid crystal layer and along a second direction crossing said first direction, wherein each of said second electrodes has contact terminals associated with said through holes, and each of said contact terminals, which does not mask said entire through hole, has a second contact area keeping a predetermined distance from said corresponding first contact area of said first electrode.

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.
