Abstract
An optical pressure touch device, a manufacturing method thereof, and a touch display apparatus, so as to reduce the influence on the display effect while realizing the touch function. The optical pressure touch device includes a first substrate, a second substrate opposite to the first substrate, a light source, and a photodetector array and a touch scanning circuit located on a side of the first substrate facing the second substrate, the touch scanning circuit being electrically connected to a photodetector in the photodetector array. A gap exists between the touch scanning circuit and the second substrate, and the light source is used to generate a light field within the gap.
