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.

Abstract: Embodiments of this application provide a flexible display and a preparation method thereof, and an electronic device. The electronic device may include a mobile terminal or an immobile terminal with a flexible display, such as a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a walkie-talkie, a netbook, a POS terminal, a personal digital assistant (PDA), a wearable device, a virtual reality device, a wireless USB flash drive, a Bluetooth sounder/headset, or a car display. A first adjustment layer and a second adjustment layer are disposed between a touch film layer and a display panel, to reduce a stress on the touch film layer in a bending process, so that the touch film layer is not prone to an open circuit risk, thereby resolving a problem that a function of the display fails because the flexible display is prone to crack in the bending process.
