Abstract: A display module includes a circuit board, an integrated chip, and a pixel chipset. The integrated chip is electrically connected to the circuit board, and the integrated chip includes a first chiplet and a plurality of display pixel drive circuits integrated into the first chiplet. The pixel chipset includes a plurality of light-emitting chips. In addition, at least one pixel chipset is disposed on a surface of a side that is of an integrated chip and that is away from the circuit board, a light-emitting chip disposed on the integrated chip is electrically connected to a display pixel drive circuit in the integrated chip, and the display pixel drive circuit is configured to drive the light-emitting chip to emit light.

Abstract: A method includes determining a first coordinate representing the geo-fence in a first coordinate system when it is detected that a geo-fence is set, where the first coordinate system is a coordinate system used by the geo-fence, converting the first coordinate into a second coordinate representing the geo-fence in a second coordinate system, where the second coordinate system is a coordinate system set to implement geo-fencing by a positioning technology, and the first coordinate system is different from the second coordinate system, comparing a coordinate of a positioning result determined using the positioning technology with the second coordinate representing the geo-fence, and triggering a preset event when a relationship between the coordinate of the positioning result and the second coordinate representing the geo-fence satisfies a trigger condition.

Abstract: A navigation method and a terminal, so as to reduce power consumption of an electronic device in a navigation process. A specific solution is that a terminal obtains start place information and destination information, and obtains information about a driving route determined according to the start place information and the destination information; the terminal obtains location information of the terminal in a moving process of the terminal; and the terminal turns off a screen of the terminal or adjusts screen brightness of the terminal from first screen brightness to second screen brightness when the location information of the terminal indicates that the terminal is on a first preset road section of the driving route, where the first screen brightness is greater than the second screen brightness. The present disclosure is applied in a navigation process and relates to the communications field.
