Description

technical field [0001] The invention relates to the technical field of directional sound generation, in particular to a conductive device with a superconducting narrow frame and a directional ultrasonic transparent screen. Background technique [0002] With the continuous development of the display market, consumers have increasingly stringent requirements on the visual effect of the display screen, not only have diversified requirements on the appearance design of the display screen, but also have higher and higher requirements on the screen ratio. The resulting trend of full-screen technology is to pursue a screen-to-body ratio greater than or equal to 90% through ultra-narrow bezel or even bezel-less designs. [0003] For directional ultrasonic transparent screens, in order to meet customer experience, the demand for ultra-narrow bezels has gradually become a rigid demand, and the lower the square resistance of the sound-emitting layer and substrate layer of directional u...
