Abstract: Disclosed are a method and an apparatus for controlling an alarm function of a mobile device with an inertial sensor. In one example of the method, after an initial threshold value is established, an alarm occurrence is generated at a predefined hour. If the alarm occurrence is the first, an alarm control unit detects a first movement of the mobile device due to the alarm occurrence through the inertial sensor, and adjusts the initial threshold value according to the first movement. If the alarm occurrence is not the first, the alarm control unit detects a second movement of the mobile device through the inertial sensor, compares the second movement with the adjusted threshold value, and stops the alarm occurrence if the second movement is greater than the adjusted threshold value.

Abstract: A lamp driving device includes first, second, and third voltage converters. The first voltage converter converts a direct current (DC) power voltage to a first pulse voltage. The second voltage converter converts the DC power voltage to a second pulse voltage. The third voltage converter generates a high alternating current (AC) voltage based on the first and second pulse voltages. The lamp driving device generates the high AC voltage without a transformer, so that a manufacturing cost of a display apparatus adopting the lamp driving device may be reduced.
