Liquid crystal display module comprising a polarizer having a plurality of conductive layers and having a touch sensing capability

摘要

A liquid crystal display module includes a liquid crystal module and a polarizer on the liquid crystal module. The liquid crystal module includes an upper substrate, an upper electrode layer, a first alignment, a liquid crystal layer, a second alignment layer, a thin film transistor panel, and a lower polarizing layer. The polarizer includes a first transparent conductive layer, an upper polarizing layer, and a second transparent conductive layer on the second surface of the upper polarizing layer. A number of first electrodes are electrically connected with the first transparent conducive layer, a number of second electrodes are electrically connected with the second transparent conducive layer. The first transparent conductive layer includes a number of carbon nanotubes substantially aligned along a second direction, and the second transparent conductive layer includes a number of carbon nanotubes substantially aligned along a first direction.
