Abstract: An electronic device includes a display and an input region separate from the display. The device detects a first portion of a first input on the input region. In response to detecting the first portion of the first input: if the first portion of the first input meets first criteria that do not require a characteristic intensity of the first input to increase above a first intensity threshold in order to be met, the device displays a precursor object of a user interface object that includes one or more selectable options. While displaying the precursor object, a second portion of the first input is detected on the input region, wherein an intensity of the first input increases above the first intensity threshold. In response to detecting the increase in intensity, the device reveals the user interface object by an amount that varies with a current intensity of the first input.

Abstract: In an ultraviolet LED chip, an epitaxial structure can be isolated into two insulated structures, i.e. a first and a second epitaxial structures by growing the epitaxial structure on a surface of a substrate, and arranging an insulating layer and a groove contacting layer in the middle of the epitaxial structure. The N-type AlGaN layer is stretched out through the groove contacting layer.
