TOUCH SENSING OPTICAL SYSTEM AND DISPLAY DEVICE INCLUDING THE SAME

摘要

An optical system includes: a first panel including a plurality of first electrodes extending in a first direction; a second panel facing the first panel and including a plurality of second electrodes extending in a second direction crossing the first direction; an optical conversion layer between the first panel and the second panel; and a first insulating layer between the first electrodes and the second electrodes, the first insulating layer including an organic material, wherein, in a touch mode, one or more of the first electrodes and one or more of the second electrodes crossing each other form a touch sensing capacitor, and wherein, in a multi-view mode, the first electrodes and the second electrodes apply an electric field to the optical conversion layer, the electric field depending on a voltage difference between the first electrode and the second electrode, to generate different phase differences.
