摘要： Provided is a display substrate, which includes a base substrate, a circuit structure layer disposed on the base substrate, multiple ultrasonic sensing elements and multiple micro light-emitting elements. The multiple ultrasonic sensing elements are disposed on a side of the circuit structure layer away from the base substrate, and are electrically connected to the circuit structure layer, and the multiple light-emitting elements are disposed on the side of the circuit structure layer away from the base substrate, and are electrically connected to the circuit structure layer. An orthographic projection of the multiple ultrasonic sensing elements on the base substrate does not overlap with an orthographic projection of the multiple micro light-emitting elements on the base substrate.

摘要： Provided are a display panel and a preparation method thereof, and a display apparatus. The display panel includes a first display region, and the first display region includes multiple sub-display regions and a first light transmittance region located between adjacent sub-display regions. Each first sub-display region of the multiple sub-display regions includes a first light-emitting element and a first filter unit disposed in a first light-emergence direction of the first light-emitting element. Each second sub-display region in the multiple sub-display regions includes a first collimating light extraction element disposed in a second light-emergence direction of the first light-emitting element and a second filter unit disposed in a light-emergence direction of the first collimating light extraction element.

摘要： A piezoelectric device includes: a base having at least one hole, a heat conductive portion disposed in the at least one hole and in contact with a wall of the at least one hole, and at least one piezoelectric sensor disposed on the base. A thermal conductivity of the heat conductive portion is greater than a thermal conductivity of the base. Each piezoelectric sensor includes: a first electrode, a piezoelectric pattern made of a piezoelectric material and a second electrode that are sequentially stacked in a thickness direction of the base.
