TOUCH SENSING LIQUID CRYSTAL DISPLAY COMPATIBLE WITH LINEARLY POLARIZED SUNGLASSES

摘要

A touch sensing liquid crystal display is made with a stack of layers that has controlled or low birefringence. The final layers of the output of the touch sensing liquid crystal display circularly polarize the output light. The combination of low birefringence and circularly polarized output light provides a touch sensing LCD that can be viewed from many angles with low visible artifacts, even through linear polarizing objects, such as sunglasses.
