    摘要: The present disclosure relates to the field of touch display technology, and in particular, provides a touch display apparatus and a driving method therefor. Specifically, the touch display apparatus includes a first substrate and a second substrate opposite to each other, a light source on a side of the second substrate facing the first substrate, a plurality of touch sensors in an array on a side of the first substrate facing the second substrate, and one or more interference color filters on a side of each touch sensor facing the second substrate. Specifically, the light source is configured to emit light towards each interference color filter. Further, each interference color filter comprises a first sub-interference color filter, a second sub-interference color filter and a third sub-interference color filter configured to output different colors of light respectively.

    摘要: 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.
