A bidirectional switch includes a pair of transistors, with each transistor including a source connected via a degeneration resistance to a common source control node, a gate connected to a common gate control node, a drain connected to a respective channel or gate line and to a charge storage node, respectively, and a clamp diode connected between the source and the gate. This forms a single charge transfer path between gate lines sequentially activated by a scan driver of an lcd panel, and implements a charge sharing technique for reducing power dissipation..

Method and driving a display device with charge sharing


A driving device for a display device is disclosed. The driving device includes a first output buffer, for generating a first source driving signal at a first output end; a second output buffer, for generating a second source driving signal at a second output end; and an electric charge storage unit, including a voltage sensing end coupled to the first output buffer and the second output buffer, for receiving and storing electric charges released by the first output buffer via the voltage sensing end when a level of the first source driving signal decreases, and for outputting the electric charges to the second output buffer via the voltage sensing end when a level of the second source driving signal increases..

Conversion gain modulation using charge sharing pixel


An image sensor including an array of pixel elements is operated according to two operation modes to modulate the conversion gain of the pixel to operate the image sensor based on the impinging light conditions. More specifically, an image sensor pixel element is operated in a high conversion gain mode for low light conditions and in a low conversion gain mode for bright light conditions.
