Abstract: A terminal is provided, and the terminal includes a housing, a front screen, a circuit board, and a power supply. The front screen is disposed on the housing, both the circuit board and the power supply are disposed inside the housing, and the power supply is connected to the circuit board. The front screen includes a toughened glass, a color changing layer, and a display screen that are sequentially stacked. The color changing layer is connected to the circuit board, and can change a color when receiving power supply. The color changing layer is disposed in the front screen, and may change a color when receiving the power supply from the circuit board. The color changing layer is configured only to change a color and cannot display a complex image, and power consumption of the color changing layer is far less than that of the display screen.

Abstract: Embodiments of this application provide an optical fiber ferrule, where n rows of optical fiber holes are symmetrically distributed on a mating end face of the ferrule, n>=3, and n is an odd number. Based on the layout design of optical fiber holes on the optical fiber ferrule, this application provides an optical fiber connector that includes a plurality of rows of optical fiber holes and that is compatible with one row and a relatively small number of rows of optical fiber holes, so that an optical fiber connector with a large number of cores can be forward compatible with an optical fiber connector with a small number of cores, thereby improving expandability and compatibility of the optical fiber ferrule.

Abstract: Embodiments of the present disclosure provide a die casting aluminum alloy, including constituents with the following mass percentages: silicon: 4.0% to 10.0%; magnesium: 0.2% to 1.0%; copper: ≤0.1%; manganese: ≤0.1%; zinc: ≤0.1%; ferrum: ≤1.3%; titanium: ≤0.2%; inevitable impurities: ≤0.15%; and the rest: aluminum. The die casting aluminum alloy has a high heat-conducting property, good formability, high corrosion resistance, and a good mechanical property. This can resolve a prior-art problem that forming and heat dissipation requirements of a communications product with a complex structure, high heat flux density, and large power cannot be met at the same time because it is difficult for a die casting aluminum alloy to have both a high heat-conducting property and good formability. The embodiments of the present disclosure further provide a production method of the die casting aluminum alloy and a communications product.
