摘要： Ultrasonic energy has been proven that at suitable frequency range (670-kHz to 2-MHz), ultrasound can be focused to a specific target, and the concentrated energy has sufficient high acoustic pressure so that capable of inducing localized blood-brain barrier (BBB) disruption, which has an important implication on noninvasively delivering drug into brain.

摘要： A contrast ratio promotion method for a display device is provided. The display device contains a back light module having a brightness and has a maximum luminance. The contrast ratio promotion method comprises the steps of continuously receiving a picture signal during each unit time, continuously calculating a ratio of a luminance of a picture corresponding to the picture signal to the maximum luminance, where the ratio is defined as an instant relative luminance, setting a first ratio, a first buffer time and a first adjusting time, and gradually reducing the brightness of the back light module to a minimum brightness during the first adjusting time when a first cumulated time for the respective consecutive plural instant relative luminances being smaller than the first ratio is longer than the first buffer time.
