Abstract
The present invention relates to a touch display apparatus, which is including a display unit and a touch unit installed under the display unit. The display unit includes a first substrate and a second substrate installed in parallel. The touch unit includes a third substrate installed under the second substrate in parallel, and a plurality of first electrodes and a plurality of second electrodes separately installed on the lower surface of the second substrate and on the upper surface of the third substrate and facing each other. When a user touches the display unit of the electronic reading apparatus, the display unit will have a local deformation accordingly, the first electrode and the second electrode touch each other, and thus a touch signal is generated. Therefore, a touch function can be achieved.
