  • Patent number: 8334549
    Abstract: A light emitting diode and a fabricating method thereof are provided. A first-type semiconductor layer, a light emitting layer and a second-type semiconductor layer with a first surface are sequentially formed a substrate. Next, the first surface is treated during a surface treatment process to form a current-blocking region which extends from the first surface to the light emitting layer to a depth of 1000 angstroms. Afterward, a first electrode is formed above the current-blocking region of the second-type semiconductor layer, and a second electrode is formed to electrically contact to the first-type semiconductor layer. Since the current-blocking region is formed with a determined depth within the second-type semiconductor layer, the light extraction efficiency of the light emitting diode may be increased.

  • Publication number: 20120081853
    Abstract: A medical antibacterial full-flat touch screen comprises an antibacterial housing, an antibacterial rubber strip and an antibacterial full-flat panel, wherein a recessed edge is configured around the periphery at the bottom of the antibacterial rubber strip which recessed edge encompassing the periphery of the antibacterial full-flat panel, and a plurality of upright buckle holes are configured on the inner side of the periphery of the antibacterial full-flat panel. In addition, a groove is configured around the periphery at the top of the antibacterial rubber strip such that the antibacterial housing can be directly inserted into the groove, and a plurality of bumps configured on the inner side of the antibacterial housing can be positioned into the upright buckle holes thereby allowing the antibacterial housing and the antibacterial full-flat panel to combine together.

  • Publication number: 20120084728
    Abstract: A button control system for medical touch screen and method thereof comprises a central control module, a touch signal input module, a lock time control module, a button lock module, a button unlock module and a cleanse display module, wherein the central control module determines the signal inputted by the touch signal input module, and selects to control the button lock module or the button unlock module thereby locking or unlocking a touch button; furthermore, the lock time control module is configured to set up the lock time for the touch button so as to preset the lock time of the touch button as cleansing the touch screen by the user, and after pressing down the cleanse touch button on the touch screen, it allows to control to lock or unlock other touch buttons and also to effectively prevent the occurrence of the situation where the screen button is erroneously touched as performing the cleanse process.
