Abstract: An example touch display apparatus includes a touch display panel including one or more touch areas. Each touch area can include touch structures, where each touch structure includes first touch electrodes arranged along a first direction and second touch electrodes arranged along a second direction. Each first touch electrode can include first electrode blocks arranged along the second direction. Each second touch electrode can include second electrode blocks arranged along the first direction. The display apparatus can further include at least one touch driver chip, where one touch driver chip is electrically connected to a touch signal line connected to touch structures in one touch area.

Abstract: This application provides an organic light-emitting touch display panel and an organic light-emitting touch display apparatus, including a display layer (10), a touch layer (20), and a packaging layer (30) disposed between the display layer (10) and the touch layer (20), where the three layers are disposed along a thickness direction of the organic light-emitting touch display panel, and the touch layer (20) is disposed on the packaging layer (30). The display layer (10) includes a plurality of display units (11), and the display unit (11) includes a first electrode (111), a second electrode (112), and an organic light-emitting layer (113) disposed between the first electrode (111) and the second electrode (112). The touch layer (20) includes a touch-sensitive layer, a first insulation layer (23), and a touch wiring layer that are disposed in the thickness direction of the organic light-emitting touch display panel, and the first insulation layer (23) is disposed between the touch-sensitive sensitive layer and the touch wiring layer. The touch-sensitive layer includes a plurality of touch- electrodes (21) that are insulated from each other, the touch wiring layer includes a plurality of touch sensor traces (22), and the touch-sensitive electrodes (21) are electrically connected to at least one touch sensor trace (22). The organic light-emitting touch display panel reduces impact of the touch layer on a voltage signal of the display layer, reduces touch blind spots, and improves touch accuracy.
