摘要： A control circuit includes a power supply, a control IC, a liquid crystal panel, a driving integrated chip arranged between the control IC and the liquid crystal panel, and a number of voltage adjusting sub-circuits. The driving integrated chip includes a plurality of output ports for outputting a plurality of driving voltages respectively. Each voltage adjusting sub-circuit is arranged between the corresponding output port of the driving integrated chip and the liquid crystal panel for adjusting an initial value the voltage outputted from the corresponding output port before the driving voltage is transferred to the liquid crystal panel. With the voltage adjusting sub-circuits, the driving voltages received by the liquid crystal panel have the same value to avoid the color deviation of the images displayed in the liquid crystal panel. This improves the display effect of the liquid crystal panel under without increasing the layout area.

摘要： A light emitting diode (LED) dimming drive device, an LED dimming drive method and a liquid crystal display (LCD) are disclosed. The LED dimming drive device comprises a plurality of dimming control circuits each comprising one dimmer switch and a delay setting circuit for setting a different delay time for each dimming control circuits. Each of the dimming control circuits further comprises a clock delay circuit for receiving a pulse width modulation (PWM) signal, timing according to the delay time, and outputting the PWM signal to the dimmer switch when the delay time expires. Different delay times can be used to control the output of PWM signals and further control the on or off of the dimmer switches.

摘要： A liquid crystal display (LCD) overdriving method, an LCD overdriving device and an LCD are disclosed. The LCD overdriving method improves displaying quality and a response speed of the LCD comprising the following steps of: receiving by a scaling controller, a previous frame image grayscale value stored into a frame buffer of the scaling controller; receiving a next frame image grayscale value by the scaling controller and sending the previous frame image grayscale value and the next frame image grayscale value to a time schedule controller so that the time schedule controller looks up a lookup table and outputs an overdriving grayscale value. The present disclosure can effectively save the cost by eliminating the need of providing an additional frame buffer in the time schedule controller. Furthermore, as image grayscale values of only two pixels need to be stored in the time schedule controller, it can save more memory spaces.
