Abstract: Provided is a display panel. The display panel includes a base substrate, a plurality of first pixels, and a plurality of second pixels. The base substrate is provided with a special-shaped display region, and the special-shaped display region includes a special-shaped edge region and a main display region which are sequentially arranged along the direction distal from the special-shaped edge. The first pixels are disposed in the main display region. The second pixels are disposed in the special-shaped edge region. In the case that the display panel displays a picture of a target gray level, the potentials of the drive signals transmitted to the light-emitting elements by the pixel circuits in the second pixels with different distances from the special-shaped edge are different and are smaller than the potentials of the drive signals transmitted to the light-emitting elements by the pixel circuits in the first pixels.

Abstract: An atomizing liquid gel with reversible phase transition characteristics includes: a sugar-based gelling agent, 0.1-3.0 wt %; an atomizing liquid, 97.0-99.9 wt %; a molecule of the sugar-based gelling agent is a sugar molecule introduced with an amide group and/or an aryl group, and the sugar molecule optionally further includes at least one hydrophobic structural part selected from —CxHy, —O—CxHy and and x>2 and y>2. The atomizing liquid gel has characteristics of thermal reversible phase transition and/or shear reversible phase transition, a temperature of gel-sol phase transition is 100° C.-248° C., and a critical shear stress of the gel-sol phase transition is 40-800 Pa. Under heating and/or oscillation, the atomizing liquid gel converts from the gel state to a sol state, and the atomizing agent fixed in the gel releases to form an inhalable aerosol.

Abstract: An electromagnetically-driven liquid atomization device includes an atomizing core and an electromagnetic drive unit, where the atomizing core includes a liquid storage tank and an electrical heating element; the electrical heating element is provided above a droplet releasing hole, such that a surface of the electrical heating element and the droplet releasing hole are opposite and spaced apart by a certain distance; the electromagnetic drive unit is provided at the bottom of the atomizing core. The electromagnetically-driven liquid atomization device of the present disclosure features small size, quantitative liquid supply, small-volume liquid atomization, controllable droplet formation and liquid surface shape, and no liquid leakage.

Under heating and/or oscillation, the atomizing liquid gel converts from the gel state to a sol state, when the heating and/or oscillation are stopped, the atomizing liquid gel is quickly recovered from the sol state to the gel state.

Abstract: A variable-frequency surface acoustic wave electronic cigarette includes an atomizer. An atomization cavity is disposed in the atomizer, and a variable-frequency surface acoustic wave atomization chip is disposed at a lower portion of the atomization cavity. An inverted trapezoidal interdigital transducer is disposed on the variable-frequency surface acoustic wave atomization chip. An e-liquid storage cavity is disposed in the atomization cavity. A porous ceramic sheet is disposed between the e-liquid storage cavity and the atomization chip. The new variable-frequency surface acoustic wave electronic cigarette can realize any adjustment of the working frequency within a set range, thereby realizing the autonomous regulation and control of a smoke particle size after atomization of the e-liquid.
