Abstract: A method of compensating a physical variation of an optical modulator and a display device to which the method is applied are provided to compensate a driving signal for the same input to obtain uniform luminance and output images with uniform texture all the time. A compensation driving pattern is output to an optical modulator within a first blank time between image frames(S1010). A first sampling luminance of a modulated light output from the optical modulator is measured according to the compensation driving pattern(S1020). A feedback driving pattern is output within a second blank time between image frames(S1030). A second sampling luminance of the modulated light output from the optical modulator is measured according to the feedback driving pattern(S1040). A feedback sampling luminance is calculated from the first sampling luminance and the second sampling luminance(S1050). The relationship between a driving signal and luminance in the optical modulator is produced from the feedback driving pattern and the feedback sampling luminance to update a reference table which represents the relationship between the driving signal and the luminance(S1060).

Abstract: A color display apparatus using two panels is provided to simplify an optical system and a circuit by using a smaller number of panels than a color display apparatus of a three-panel type and increase durability of a scanner by adopting a bidirectional scanning method. A buffer memory stores RGB(Red, Green and Blue) color information corresponding to one frame. An image processing unit fetches the RGB color information from the buffer memory and extracts fixed-color image information corresponding to a beam of a fixed color and varied-color image information corresponding to a beam of a varied color. A fixed-color panel(730) modulates the beam of the fixed color according to the fixed-color image information and generates a modulated beam of the fixed color. A varied-color panel(740) modulates beams of the varied color according to a plurality of the varied-color image information and sequentially generates modulated beams of the varied color. A color synthesis system(750) synthesizes the modulated beams of the fixed color and the varied color, and creates a synthesis signal. A projective optical system scans the synthesis signal onto a screen in two directions.
