    Abstract: A screen includes a screen pixel array, row and column lines, a display driver integrated circuit (DDIC) circuit, a gate driver on array (GOA) circuit, a switch circuit, and an enabling signal circuit. The DDIC circuit is disposed on a side of a screen of the electronic device, and includes output channels. Each output channel is connected to two switches, each switch is connected to one row line, the GOA circuit is connected to a column line, the enabling signal circuit is connected to the switch circuit, and the screen pixel array is connected to the row and column line. The enabling signal circuit generates an enabling signal for the switch circuit. The DDIC circuit sends to-be-displayed data to the switch circuit. The switch circuit controls the two switches to alternately operate. The GOA circuit strobes a column of pixels in the screen pixel array which displays the to-be-displayed data.

    IPC: G06V40/13

    CPC classification number: G06V40/1318

    Abstract: This application provides an optical signal processing circuit and an electronic device, to improve a signal-to-noise ratio of an output signal of a fingerprint sensor, thereby improving a fingerprint recognition rate. The optical signal processing circuit includes a photosensitive device, an amplifier transistor T1, a switch transistor T2, a switch transistor T3, a readout circuit, a control circuit, and a voltage-adjustable power supply. When the optical signal processing circuit is in a compensation reset phase, the voltage of the gate of T1 exactly reaches a level at which the amplifier transistor T1 is turned on. Therefore, when an input voltage and a voltage increment are applied to the gate of T1, a gate-source voltage Vgs of T1 increases, and T1 amplifies an input voltage signal to generate an output signal.

    Abstract: This application provides a fingerprint collection apparatus. According to the fingerprint collection method and the related apparatus that are provided in this application, a sensor array is divided into a plurality of areas in terms of a column based on a quantity of input ports of an analog front end component and a quantity of columns of the sensor array, and sensor units in different areas multiplex input channels of the analog front end component by using switches. In this way, when scanning row scanning lines in the sensor array, a row scanning circuit may control the switches to output, to the analog front end component in a time division manner, original fingerprint data collected by the sensor units in the different areas, so that fewer input channels of the analog front end component can be required, and a size of a fingerprint collection apparatus can be reduced.

    Abstract: A terminal and a method for detecting luminance of ambient light, where the terminal includes a processor, an ambient light sensor, and a screen. The ambient light sensor and the screen are both coupled to the processor. A light-sensitive element of the ambient light sensor faces the screen and is located on a lower surface of the screen. After the screen is lit up, the processor adjusts first luminance of the screen to a value below a first threshold within a visual persistence time of human eyes. The ambient light sensor detects luminance of first ambient light of the terminal within the visual persistence time of human eyes. The terminal may eliminate non-ambient light that enters the ambient light sensor such that the ambient light sensor may detect luminance of relatively real ambient light.

    Abstract: A terminal management method and an apparatus, where the method includes that a terminal obtains a first light intensity at a first moment and a second light intensity at a second moment according to a first interval period. The second moment is later than the first moment. When a difference between the first light intensity and the second light intensity is greater than a first threshold, and the second light intensity is less than a second threshold, the terminal closes a target program. It can be learnt from above that, the terminal can determine, according to a variation in light intensities, whether the terminal is blocked by clothes, and close the target program. This reduces running power consumption of the terminal and increases a standby time of the terminal.
