TIMING CONTROLLER WITH FREQUENCY MODULATION, CONVERTER WITH FREQUENCY MODULATION FOR SCANNING-BASED BACKLIGHT UNIT MODULE, AND CONTROL SYSTEM FOR 3D DISPLAY
First Claim
1. A timing controller with frequency modulation, comprising:
- a frame rate detection unit, in response to a first display signal, outputting a detection signal indicating a first frame rate at which the first display signal is; and
a display frequency modulation unit, coupled to the frame rate detector, the display frequency modulation unit, in response to the first display signal and the detection signal, outputting a second display signal at a second frame rate greater than or substantially equal to the first frame rate selectively,wherein the second display signal indicates digital signals for presentation by a display in a 3D mode in which the second frame rate is greater than the first frame rate and the second display signal indicates digital signals for presentation by a display in a 2D mode in which the second frame rate is substantially equal to the first frame rate.

Abstract
Timing controller with frequency modulation, converter with frequency modulation for scanning-based backlight unit module, and control system for 3D display. A timing controller with frequency modulation performs display frequency modulation of a first frame rate of a first display signal and outputs a second display signal at a second frame rate greater than or substantially equal to the first frame rate for presentation by a 3D display in a 3D mode or a 2D mode, selectively. A converter with frequency modulation performs scanning frequency modulation of a first scanning frequency of a first control signal generated from the converter and outputs a second control signal at a second scanning frequency greater than or substantially equal to the first scanning frequency, selectively, for controlling the scanning-based backlight unit module of the 3D display.
