Abstract: An array substrate including a display area having a plurality of subpixels is provided. The plurality of subpixels includes a plurality of first subpixels in a display-bonding sub-area and a plurality of second subpixels in a regular display sub-area. The array substrate includes a plurality of thin film transistors on a first side of the base substrate and respectively in the plurality of subpixels. A respective one of the plurality of first subpixels includes a bonding pad on a second side of a base substrate; a lead line electrically connecting a respective one of a plurality of thin film transistors to the bonding pad; and a via extending through the base substrate. The lead line is unexposed in the array substrate. The lead line extends from the first side to the second side of the base substrate through the via, to connect to the bonding pad.

Abstract: A cavity optomechanical vibratory gyroscope pertains to technical fields of resonant optical gyroscopes and micro-optical-electro-mechanical systems. A novel cavity optomechnical Coriolis vibratory micro gyroscope is realized based on ring micro rings and the Coriolis vibration principle, and driving and detection thereof is completely different from conventional electric or magnetic means. Based on the principle of angular velocity sensitive structures in the conventional Coriolis vibratory gyroscopes, full-optical driving, detecting and sensing of a vibratory gyroscope are achieved using cavity optomechnical technologies, which fundamentally suppresses various noises (including thermal noise, cross interference, connection point noise and quadrature error) introduced by electric or magnetic driving. Besides, displacement (vibration) sensing information is obtained according to a linear relationship between frequency shift and light amplitude in the micro cavity optomechnical effect.
