    • A luminance control device and method are disclosed. A surrounding brightness of a touch panel is measured to obtain a measured surrounding brightness. A luminance of the touch panel is controlled during a first time period starting from when the measured surrounding brightness changes from a first condition to a second condition, during which the measured surrounding brightness decreases by an amount equal to or greater than a threshold value. The luminance of the touch panel is maintained at a first luminance corresponding to the first condition when the measured surrounding brightness changes from the second condition to the first condition. The luminance of the touch panel is controlled to change to a second luminance corresponding to the second condition, when the measured surrounding brightness has not changed from the second condition to the first condition.
    • 公开了一种亮度控制装置和方法。 测量触摸面板的周围亮度以获得测量的周围亮度。 在从测量的周围亮度从第一状态变化到第二状态的第一时间段期间控制触摸面板的亮度,在此期间测量的周围亮度降低等于或大于阈值的量。 当测量的周围亮度从第二状态变为第一状态时,触摸面板的亮度保持在与第一状态相对应的第一亮度。 当所测量的周围亮度从第二状态变为第一状态时,控制触摸面板的亮度变为对应于第二状态的第二亮度。
