Abstract
A touch panel includes a first substrate, a liquid crystal layer, a second substrate, a first optical detection layer, and a black matrix. The first optical detection layer is over a light-emitting surface of the liquid crystal layer and includes a plurality of first optical detection components, whose orthographic projections on the first substrate are within an orthographic projection of the black matrix. A touch control can be determined based on a change of a first electric signal converted by each first optical detection component based on an intensity of a light transmitting through the liquid crystal layer. The light can be an infrared light. A plurality of second optical detection components can be further disposed over a light-incident surface of the liquid crystal layer to pairingly correspond to, and utilized to determine a touch control along with, the plurality of first optical detection components.
