The present invention relates to the field of the circuit technology, specifically to a signal automatic transformation device. The signal automatic transformation device comprises a frequency voltage transformation module, a power supply transformation module, a two divided-frequency module and a controlled switch module; the frequency voltage transformation module, the power supply transformation module and the controlled switch module are electrically connected in order; the two divided-frequency module is electrically connected with the frequency voltage transformation module and the controlled switch module; the frequency voltage transformation module is configured to obtain frequency signals and convert the frequency signals to control signals; the power supply transformation module is configure to output voltages with different voltage values to the controlled switch module according to the control signals; the two divided-frequency module is configured to perform frequency division of frequency signals; and the controlled switch module is configured to output driving voltage according to the voltage outputted by the power supply transformation module, the original frequency signals and the frequency signals after frequency division. The signal automatic transformation device is able to output control signals to a liquid crystal light valve only in the state of the stable signals outputted by a signal source so as to reduce unnecessary loss of the signal automatic transformation device.
Description
Technical field [0001] The present invention relates to the field of circuit technology, and in particular to a signal automatic conversion device. Background technique [0002] With the continuous development and maturity of 3D imaging technology and the continuous innovation of 3D projection equipment, the projection of images has entered the 3D era. The liquid crystal light valve is a liquid crystal phase retardation device that realizes the phase retardation of polarized light by controlling the phase alignment of liquid crystal molecules by voltage. Applying different voltages to the liquid crystal light valve will cause the phase sequence of the liquid crystal molecules to change. When a 3D projection device plays a 3D image, it will achieve the 3D effect of the 3D image by changing the driving signal that controls the liquid crystal structure. [0003] At present, the specific implementation of the liquid crystal light valve drive scheme is generally based on a microcontro...
