Abstract
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.
