- a display comprising one first substrate, one second substrate, a bottom polarizer and a liquid crystal layer, wherein said liquid crystal layer is located between said first substrate and said second substrate, said bottom polarizer being located on a first surface of said second substrate;
a top polarizer, said top polarizer being located above said first substrate; and
a resistance pressure sensing mechanism for sensing a resistance of a position of pressure on the touch panel, said resistance pressure sensing mechanism including;
a plurality of parallel strips arranged to form first electrodes, said first electrodes being located on a second surface of said first substrate between said top polarizer and said first substrate;
a plurality of parallel strips arranged to form second electrodes, said second electrodes being located between said top polarizer and said first substrate; and
a plurality of spacers, said spacers being located between said top polarizer and said first substrate or between said top polarizer and said first electrodes;
wherein a projection of said first electrodes on said first substrate intersects a projection of said second electrodes on said first electrodes.
