Abstract: Provided are a display panel and a display device. The display panel includes a substrate; sub-pixels on a side of the substrate, where the sub-pixels include light-emitting layers respectively, and each of at least one light-emitting layer includes an internal region and an edge region surrounding the internal region; and a first structure layer, on a light-emitting side of the light-emitting layers, and including lens sets each including microlenses, where the lens sets correspond to the sub-pixels one by one. The lens set includes a first region corresponding to the internal region and a second region corresponding to the edge region, and a density of microlenses in the second region is smaller than a density of mircolenses in the first region. According to the present disclosure, a display effect is improved.

Abstract: A cryogenic laser shock device and method are provided. The device includes a cooling box, a transition chamber, a laser shock chamber, and a master control system. In the method, a sample is cooled by the cooling box, a temperature of the sample is measured in real time by a cryogenic probe, gas in the cooling box is pumped out after the temperature of the sample is stabilized to a set temperature, the cooling box is moved to the laser shock chamber in a vacuum state, and a cryogenic laser shock is implemented through cooperation of a mechanical arm and a three-dimensional motion platform.
