Abstract: A method for detecting an active pen touch position, and an electronic terminal are provided. 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: 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.
