Abstract: A method for quickly entering an application includes detecting a first operation, where the first operation is used to change the electronic device from the folded form to an unfolded form, wherein when the electronic device is in the unfolded form, the included angle between the first region and the second region is greater than a second preset angle, and wherein the second preset angle is greater than the first preset angle, and displaying display interfaces of one or more preset applications in the first region, the second region, and/or the third region in response to the first operation. In the method, when the electronic device changes from the folded form to the unfolded form, a preset application may be quickly entered.

Abstract: A stylus detection method includes detecting, by a terminal, an input signal of a stylus at a first frequency, receiving a first input of the stylus through a touchscreen, detecting, in response to the first input, the input signal of the stylus at a second frequency, detecting the input signal of the stylus at a third frequency when detecting the input signal of the stylus at the second frequency and when a duration in which the terminal does not detect the input signal of the stylus is greater than a first time period. The second frequency is greater than the third frequency and the third frequency is greater than the first frequency.

Abstract: An electronic device photographing method includes, after the electronic device enters a photographing screen, determining a folding angle of the flexible display screen based on a pixel coordinate parameter of a photographed object on the photographing screen; and/or determining target luminance of a display screen; and when detecting that a photographing button is pressed, adjusting luminance of the display screen to the determined target luminance. In this way, when the electronic device is used to take an image, fill-in light can be implemented for the photographed photo by improving target luminance of the display screen based on the pixel coordinate parameter of the photographed object on the photographing screen.

Abstract: A touch system includes a glass cover, a polarizer, packaging glass, a thin film transistor (TFT) backplane, a transmitter (TX) circuit, and a receiver (RX) circuit, where the glass cover, the polarizer, the packaging glass, and the TFT backplane are fitted in sequence from top to bottom, and the TX circuit is located on the TFT backplane, and the RX circuit is located on the packaging glass. The TX circuit and the RX circuit are respectively disposed on the TFT backplane and the packaging glass. Therefore, a quantity of stacked layers of the touch control system is reduced. This reduces a thickness of the touch system, thereby achieving a thinner and lighter active matrix organic light emitting diode (AMOLED) display screen, and reducing a weight of a terminal product.

Abstract: A touchscreen input method and a terminal are provided. The method includes, when a signal for waking up a touchscreen is received, obtaining on the touchscreen an effective touch area that corresponds to the signal for waking up the touchscreen according to a preset correspondence between the signal for waking up the touchscreen and the effective touch area. The method also includes detecting position information of a touch point within the effective touch area and generating an operation instruction according to the position information of the touch point. The embodiments of the present invention also disclose a terminal. The terminal can accurately obtain a touch point in a preset touch area when the terminal is being woken up.
