    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: When a touch position of an active pen on a screen of an electronic terminal is detected, and once a first touch position of the active pen on the screen of the electronic terminal is detected based on downlink signals collected by sensors under the screen of the electronic terminal, sensors outside a first preset region including the first touch position are disabled, where sensors in the first preset region are still in a working mode. In addition, a quantity of sensors in the first preset region is less than a quantity of sensors under the screen of the electronic terminal. In this way, when a second touch position of the active pen on the screen of the electronic terminal is subsequently determined, downlink signals sent by the active pen are collected only by using the sensors in the first preset region, instead of always by using all sensors under the screen of the electronic terminal, so that detection flexibility is improved.

    Abstract: This application provides a touch display panel for reducing capacitive load. A package substrate includes a first metal layer and a second metal layer. The second metal layer includes conductive patterns that are arranged in a matrix form. The conductive patterns each output a first sensing signal when sensing a touch operation. Each conductive pattern includes a first area and a second area. The first area includes first metal sub-conducting wires extending in the first direction. A plurality of second metal conducting wires extending in the second direction, any second metal conducting wire is connected to one conductive pattern and is configured to transmit the first sensing signal to a touch controller.

    Abstract: A terminal includes a cover, a display module, and a metal middle frame. The display module is located between the cover and the metal middle frame, and the metal middle frame is grounded. The terminal further includes a conducting layer, where the conducting layer is attached to a lower surface of the display module, and at least one gap exists between the conducting layer and the metal middle frame. The conducting layer, the metal middle frame, and the at least one gap form at least one capacitor, where a capacitance change of the at least one capacitor reflects a magnitude of at least one pressure acted on the cover.

    Abstract: An electronic device control method is provided. The method may be applied to an electronic device having a touchscreen. A display drive circuit and a touch sensor that match the touchscreen are configured in the electronic device. The method includes: The display drive circuit performs pixel scan. The touch sensor collects a touch signal once after the display drive circuit scans S rows of pixels each time, where S≥1. Touch signals collected N consecutive times are used as one group. An uplink synchronization signal is transmitted to the outside in a slot for collecting a touch signal for the Kth time in each group, where 1≤K≤N. The uplink synchronization signal is used to perform time alignment with an external device.
