  • Patent number: 10928969
    Abstract: An input device includes a structural frame, a touch pad, a piezoelectric sheet fixed on the touch pad, and a controller electrically connected to the touch pad and the piezoelectric sheet. The touch pad has a first side, a second side opposite to the first side, and a touch-sensitive surface that has a button area located at the second side. The touch pad can be elastically deflected to move the second side relative to the structural frame. The piezoelectric sheet generates a voltage when the touch pad is elastically deflected. When determining that a press is performed on the button area and the voltage is larger than or equal to a corresponding predetermined value, the controller sends out a trigger signal. An electronic apparatus with the input device includes a display screen and a processor. The processor receives the trigger signal to control the display screen to display images.

  • Patent number: 7645624
    Abstract: A method for self bonding epitaxy includes forming a passivation layer on a substrate surface of a semiconductor lighting element; etching to form recesses and protrusive portions with the passivation layer located thereon; starting forming epitaxy on the bottom surface of the recesses; filling the recesses with an Epi layer; then covering the protrusive portions and starting self bonding upwards the epitaxy to finish the Epi layer structure. Such a self bonding epitaxy growing technique can prevent cavity generation caused by parameter errors of the epitaxy and reduce defect density, and improve the quality of the Epi layer and increase internal quantum efficiency.
