    • A backlight controller, a display device using the same and a method for controlling a backlight module are provided. The backlight controller includes a temporal weighting module and a dimming controlling module. The temporal weighting module calculates a weight sum of a first backlight luminance provided in a current frame and a target backlight luminance to serve as an adjusted backlight luminance. The target backlight luminance is obtained according to an image content of the current frame. The dimming controlling module increases or decreases the adjusted backlight luminance by a step value according to the target backlight luminance and generates a second backlight luminance provided in a next frame. Therefore, a backlight luminance of the backlight module not only can be smoothly adjusted to the target backlight luminance at high speed for avoiding backlight flicker, but also can be adaptive to image content for saving electric power consumption.
    • 提供了一种背光控制器,使用其的显示装置和用于控制背光模块的方法。 背光控制器包括时间加权模块和调光控制模块。 时间加权模块计算当前帧中提供的第一背光亮度和目标背光亮度的权重和作为调整的背光亮度。 根据当前帧的图像内容获得目标背光亮度。 调光控制模块根据目标背光亮度将调整后的背光亮度增加或减小步长值,并产生下一帧中提供的第二背光亮度。 因此,为了避免背光闪烁,背光源模块的背光亮度不仅可以高速地平滑地调整到目标背光亮度,而且可以适应于用于节省电力消耗的图像内容。

    • A low voltage differential signaling (LVDS) transmitter receives a data signal, a data invert signal and a plurality of logic signals. The LVDS transmitter includes a first-stage differential signaling transmitting circuit and a second-stage differential signaling transmitting circuit. The first-stage differential signaling transmitting circuit receives the data signal and the data invert signal and has a first output terminal and a second output terminal. The second-stage differential signaling transmitting circuit is controlled by the logic signals, and has a third output terminal and a fourth output terminal respectively connected to the first output terminal and the second output terminal, so as to generate a needed pre-emphasis signal. When no pre-emphasis signal needs to be generated, the second-stage differential signaling transmitting circuit is controlled to be in disabled state.
