摘要： An image display system comprises red, green and blue laser light source units (22 to 24), a spatial light modulator (25) that modulates the laser lights of different colors in a time sharing manner and a control unit (13) for controlling the operation of the laser light source units and the spatial light modulator. The green and red laser light source units are lighted in that order in each frame. The green color is diminished owing to the response delay of the spatial light modulator, but the green laser light produced by the green laser light source unit (23) has a relatively large color phase shift from the standard green color so that the shortage of green color cancels out with the color phase shift of the generated green color so that the color phase shift of the displayed intermediate color can be minimized.
摘要翻译：图像显示系统包括红，绿和蓝激光光源单元（22至24），以时分方式调制不同颜色的激光的空间光调制器（25）和用于控制激光光源单元和空间光调制器的操作。绿色和红色的激光光源单元在每一帧中依次点亮。由于空间光调制器的响应延迟，绿色减弱，而由绿色激光光源单元（23）产生的绿色激光具有从标准绿色相对较大的颜色相位偏移，使得绿色不足颜色会随着生成的绿色的颜色相移而消除，使得显示的中间色的颜色相移可以最小化。
