摘要： A method for driving a dark ring of a liquid-crystal-on-silicon (LCOS) display is provided to prevent the fringe effect (bright lines) due to the constant voltage difference between the dark ring and the adjoining pixels within the LCOS display. A dark ring is divided into a plurality of portions. The polarity of each portion is controlled in accordance with the polarity of the adjoining pixels within the LCOS display and the scan direction of gate drivers such that the polarity inversion for each portion will coincide with that for the adjoining pixels within the LCOS display so as to avoid the fringe effect (bright lines).

摘要： The continuing need for faster and denser SRAM memories places a constant increased demand on the power consumption of the memory devices. Much of the power consumption occurs during the pre-charge phase where it is common practice to bring up all pre-charge circuits at once and hold them active until the memory operations are complete. This invention describes a design where each pre-charge circuit connected to a group of memory cells through bit lines is activated at a separate time from the other pre-charge circuits. Thus each pre-charge circuit is active only during the time that useful work is being done with that portion of the memory. This reduces power consumption by not powering on circuits and precharging bit lines before they are actually needed.
摘要翻译：对于更快和更密集的SRAM存储器的持续需求对存储器件的功耗的需求不断增加。大部分功耗发生在预充电阶段，通常的做法是一次启动所有预充电电路并保持其活动直到存储器操作完成。本发明描述了一种设计，其中通过位线连接到一组存储器单元的每个预充电电路在与其它预充电电路分开的时间被激活。因此，每个预充电电路仅在与存储器的该部分进行有用的工作的时间有效。这在实际需要之前不通过电路供电和预充电位线来降低功耗。

摘要： Embodiments of the present invention set forth methods and systems for driving display devices. In one embodiment, a first set of image data to be displayed on a display panel is stored. During a first time period, a reset signal is asserted to set the display panel associated with a common panel voltage to a predictable state. Subsequent to the first time period, a control signal is asserted to load the first set of image data for a first subframe within a frame on the display panel, wherein this first set of image data is further adjusted by a first adjustable reference voltage. A designated light for the display panel is turned on to display the first set of image data in parallel with the storing of a second set of image data for a subframe within the frame to be displayed.

摘要： The invention relates to an LED current driving system. The LED current driving system comprises an LED driver. The LED driver comprises at least one LED driving unit for outputting a driving current to an LED. Each LED driving unit comprises a plurality of current sources and a plurality of switches. The switches are connected to the corresponding current source. Each switch controls the ON/OFF state of the corresponding current source in accordance with the duty cycle control signal and a current control signal.
