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: A display panel includes a display area and a non-display area. The display area includes a touch electrode array consisting of a plurality of touch electrodes, and a plurality of touch signal wires, and the non-display area includes at least two fan-out routing areas. The at least two fan-out routing areas are arranged along a first boundary between the non-display area and the display area, and each fan-out routing area includes a plurality of touch leading wires. The fan-out routing area includes a fan-shaped area and a straight line area, and the fan-shaped area is located between the first boundary and the straight line area. Each touch leading wire includes a first sub-leading wire located in the fan-shaped area and a second sub-leading wire located in the straight line area.

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 mobile terminal, including a clock generator, a first frequency conversion circuit, a first module, a second frequency conversion circuit, and a second module. The first frequency conversion circuit performs frequency conversion on a clock signal generated by the clock generator, to obtain a first clock signal, and outputs the first clock signal to the first module. The second frequency conversion circuit performs frequency conversion on the clock signal generated by the clock generator, to obtain a second clock signal, and outputs the second clock signal to the second module. The mobile terminal has an improved anti-electromagnetic interference capability.

Abstract: Embodiments of the present invention relate to a display screen, including a glass substrate. The display screen further includes: a first electrode plate on a surface of the glass substrate; a second electrode plate at a lower part of the glass substrate, where the first electrode plate and the second electrode plate constitute a capacitor, and there is a space within a preset width range between the first electrode plate and the second electrode plate, so that when external pressure is applied to the display screen, the first electrode plate is elastically deformed; and a controller, connected to the first electrode plate and configured to: when external pressure is applied to the display screen, calculate a changed capacitance value based on a change of a distance between the first electrode plate and the second electrode plate; and calculate a pressure value based on the changed capacitance value. The first electrode plate is disposed as an electrode material on the substrate, so that a material used for separately disposing a pressure sensor can be saved. The electrode material is coated or printed on the substrate, so that a thickness of the display screen can be reduced.
