Abstract: The disclosure provides a synchronous display method of an spliced display screen which comprises at least two spliced display units and at least two timing controllers respectively corresponding to the spliced display units, wherein the method comprises steps of: receiving, by each timing controller, a timing control signal for a current frame of the corresponding spliced display unit, feedback from the spliced display unit corresponding to the timing controller; determining, by each timing controller, a phase difference between the timing control signal for the current frame of the corresponding spliced display unit and a reference timing control signal received by the timing controller; judging, by each timing controller, whether or not the phase difference goes beyond a predetermined threshold range; if it is judged that the phase difference goes beyond the predetermined threshold range, generating a phase adjustment value, by the timing controller, based on the phase difference, wherein the phase adjustm

Abstract: A holographic LCD stereo display system is disclosed. The holographic LCD stereo display system comprises: a holographic projection device (11), a signal synchronous generator (12) and a holographic LCD having multiple layer of LCD panels.
