摘要: A liquid crystal display (LCD) device's microcontroller is used drive an LCD lamp ballast such that the scrolling effect from its light leakage may be reduced to a visually imperceptible level. A check may be performed of lamp's control status in order to verify the microcontroller's ability to properly and accurately control the lamp ballast. The microcontroller may then determine a frequency and duty cycle to use for the microcontroller's PWM control signal. Thereafter, the microcontroller may generate the PWM control signal in accordance with the determined frequency and duty cycle, and drive the lamp ballast using the control signal.

摘要: To facilitate programming a TV channel list, only digital channels are presented on an edit list so that the user need not parse through analog channels but only the digital channels to edit the channels (e.g., by putting the channels on a favorite list, or a skip list, or by labelling the channels, etc.).
摘要翻译: 为了方便对电视频道列表的编程,在编辑列表上仅显示数字频道,使得用户不需要通过模拟频道解析,而只需要数字频道来编辑频道(例如,将频道放在收藏列表中,或 跳过列表,或通过标记通道等)。
