Touch display, liquid crystal display with a built-in touch panel
First Claim
1. A liquid crystal display (LCD) with a built-in touch panel, comprising:
- an LCD unit, comprising;
a lower substrate;
an upper substrate, disposed opposite to the lower substrate;
a liquid crystal layer, disposed between the lower substrate and the upper substrate;
a first polarized plate, disposed on the lower substrate;
a touch panel, disposed opposite to the upper substrate;
a second polarized plate, disposed at a side of the touch panel facing to the LCD unit, and located between the LCD unit and the touch panel; and
an air layer configured between the upper substrate and the second polarized plate and an airtight gasket disposed at a periphery of the air layer surrounding the air layer,wherein the first polarized plate and the second polarized plate are the only polarizing plates in the liquid crystal display (LCD) with a built-in touch panel,the first polarized plate has a first polarized direction, and the second polarized plate has a second polarized direction, and the first polarized direction is matched with the second polarized direction for displaying an image and preventing light reflection.

Abstract
A liquid crystal display (LCD) with a built-in touch panel includes an LCD unit, a touch panel and a second polarized plate. The LCD unit includes a lower substrate, an upper substrate, a liquid crystal layer and a first polarized plate. The upper substrate is disposed opposite to the lower substrate, and the liquid crystal layer is disposed between the lower substrate and the upper substrate. The first polarized plate is disposed on the lower substrate and has a first polarized direction. The touch panel is disposed opposite to the LCD unit. The second polarized plate having a second polarized direction is disposed on the touch panel and located between the LCD unit and the touch panel. An intensity of a reflected light occurred in the LCD with the built-in touch panel is relatively low, so that good contrast and visibility are obtained.
