摘要:
A differential signal generating device includes a control circuit and a differential signal driver receiving a single-ended signal. The control circuit receives a source signal and generates a control signal corresponding to a first mode when the source signal conforms with a first pre-defined state, and corresponding to a second mode when the source signal conforms with a second pre-defined state. Variations of the source signal are related to signal content of the single-ended signal. The differential signal driver is coupled to the control unit for receiving the control signal therefrom. The differential signal driver outputs a differential signal output according to the single-ended signal when the control signal corresponds to the first mode. The differential signal driver outputs a non-differential signal output when the control signal corresponds to the second mode.

A control device for three dimensional display has an image processor and a timing signal generator. The image processor is used for receiving a first and a second input image signals to generate a first, a second, and a third output image signals. The first output image signal comprises part of the first input image signal. The second output image signal comprises part of the first input image signal and part of the second input image signal. The third output image signal comprises part of the second input image signal. The timing signal generator is used for generating a first lens control signal for configuring a first lens to be non-opaque when the second output image signal is displayed on a display device, and generating a second lens control signal for configuring a second lens to be non-opaque when the third output image signal is displayed on the display device.

A level shifter, with body-biased circuits, is provided for applying in a thin film transistor liquid crystal display (TFT-LCD). The body-biased circuits are configured to bias the bodies of the input terminal transistors of the level shifter so that the threshold voltages of the input terminal transistors are adjustable. This level shifter is capable of operating at a high frequency with low power consumption while a low-level signal is inputting.
