TOUCH SCREEN LIQUID CRYSTAL DISPLAY
First Claim
1. A touch screen comprising a liquid crystal display with integral touch sensing, the touch screen comprising:
- a first substrate having display control circuitry formed thereon, the first substrate being disposed between the first polarizer and the second polarizer;
a second substrate disposed between the first polarizer and the second polarizer and adjacent the first substrate;
at least one touch sensing element disposed between the first and second substrates, wherein all touch sensing elements are disposed between the first and second substrates.

Abstract
Disclosed herein are liquid-crystal display (LCD) touch screens that integrate the touch sensing elements with the display circuitry. The integration may take a variety of forms. Touch sensing elements can be completely implemented within the LCD stackup but outside the not between the color filter plate and the array plate. Alternatively, some touch sensing elements can be between the color filter and array plates with other touch sensing elements not between the plates. In another alternative, all touch sensing elements can be between the color filter and array plates. The latter alternative can include both conventional and in-plane-switching (IPS) LCDs. In some forms, one or more display structures can also have a touch sensing function. Techniques for manufacturing and operating such displays, as well as various devices embodying such displays are also disclosed.
