The earphone compatible circuit controls the connection states between the contacts of the earphone interface and the ports of the controller, according to the type of earphone jack inserted into the earphone interface. The earphone compatible circuit connects corresponding contacts of the earphone jack to ports of the controller. | 09-20-2012 |
20120242617 | MIS-TOUCH AVOIDANCE METHOD AND APPARATUS OF MOBILE TERMINAL - A mis-touch avoidance method and apparatus for preventing an unintended touch made by noise generated by the attachment of an accessory or a user's grip from causing a malfunction of a mobile terminal including a touchscreen are provided. The mis-touch avoidance method includes detecting an attachment of an external device and recalibrating a reference value for touch recognition in response to the attachment of the external device. The mis-touch avoidance method also includes detecting a touch on the touchscreen, determining whether the touch is an unintended touch made by user's grip of the mobile terminal, and recalibrating a reference value for touch recognition when the touch is the unintended touch. | 09-27-2012 |
20120268438 | DISPLAY WITH A REFLECTIVE LC PANEL, AND THE DISPLAY METHOD - A display includes a reflective Liquid Crystal (LC) panel having an LC layer, an optical unit having a light source, and a transmission plate unit stacked on the reflective LC panel. The transmission plate unit includes a first transmission plate and a second transmission plate that have respective and different indexes of refraction. Light incident on a first side of the first transmission plate is totally internally-reflected by a boundary between the first transmission plate and the second transmission plate, and travels through the first transmission plate to the reflective LC panel. The LC layer of the reflective LC panel reflects the incident light of spectra corresponding to pixel signals in order to display a video. | 10-25-2012 |
20120286844 | METHOD AND APPARATUS FOR CONTROLLING DEVICE IN ELECTRONIC EQUIPMENT - A method and apparatus for controlling a device in electronic equipment having a plurality of devices are provided. The apparatus includes a power supply for supplying power, a slave device including a driving circuit operated according to the supplied power for transmitting and receiving data to and from another device, a switching circuit for connecting the driving circuit to a ground terminal when the switching circuit is turned-on and for opening the driving circuit from the ground terminal when the switching circuit is turned-off, and a host device for transmitting a control signal for turning-on the switching circuit when driving the slave device and for turning-off the switching circuit when not driving the slave device. When the device is not driven, the switching circuit may open a driving circuit from a ground terminal, thereby cutting-off leakage of an electric current through the device. | 11-15-2012 |
