摘要： PROBLEM TO BE SOLVED: To provide an LCD which reduces power consumption when frame rate conversion is used in order to improve frame picture quality and solve a motion blur of the LCD, thereby reducing heat to be generated by the LCD.SOLUTION: In an LCD, whether to perform polarity conversion to each of a plurality of frames is determined. When the frames are displayed, the conversion frequency of the polarity of the frame is smaller than an update frequency of the frame in a unit time. For example, when 120 pieces of frames are displayed per second, the polarity of a liquid crystal cell is converted to original frames 410 and 420, and not converted to an interpolated frame 410A. When 240 pieces of frames are displayed per second, the polarity of the crystal cell is converted to the original frames 410 and 420, and not converted to interpolated frames 410B, 410C, and 410D.

摘要： PROBLEM TO BE SOLVED: To provide an output buffer selectively adjusting an operation power loss. SOLUTION: The output buffer for providing an output voltage signal includes an operational amplifier, a controller and a power circuit. The operational amplifier provides the output voltage signal according to an input voltage signal. The controller determines whether a reference signal corresponding to the input voltage signal satisfies an energy-saving condition, and triggers an energy-saving operation event if yes, or triggers a normal operation event if not. The power circuit provides an energy-saving power signal to drive the operational amplifier in response to the energy-saving operation event and provides a normal power signal to drive the operational amplifier in response to the normal operation event, such that the operational amplifier provides the output voltage signal according to the input voltage signal. A voltage level of the normal power signal is higher than a voltage level of the energy-saving power signal. COPYRIGHT: (C)2010,JPO&INPIT

摘要： A light-emitting diode driving system (100) including a load (110), a power supply circuit (120) and a light-emitting diode driving device (130) is provided. The power supply circuit (120) outputs an output voltage (Vout) to drive the load (110) according to a feedback signal (FB). The light-emitting diode driving device (130) includes a current source (138), a comparator (132) and a control logic circuit (136). The current source (138) outputs a current (I1) to drive the load (110). The comparator (132) compares a first voltage (VL[1]) from the current source (138) to a reference voltage (VC) and outputs a second voltage (VX[1]) according to a comparison result. The control logic circuit (136) receives the second voltage (VX[1]) through a control node (N1) and converts the second voltage (VX[1]) to a control signal (S1) to adjust a resistance value of a variable resistor circuit (134).
