Resolution in a projected display is traditionally defined by the number of pixels in the projector's spatial light modulator (SLM). In recent years, different techniques that increase the resolution on the screen above the number of SLM pixels have gained popularity. In one such technique, called pixel‐shifting or shifted‐superimposition, the display physically shifts every n^th frame on the projected screen, and the overlapping pixel grids forms a finer subpixel grid with a higher pixel count.

源分辨率对通过移位叠加投影增强分辨率的影响

传统上，投影显示器的分辨率是由投影仪的空间光调制器（SLM）中的像素数定义的。近年来，将屏幕分辨率提高到SLM像素数量以上的各种技术已普及。在一种这样的技术，所谓的像素移或偏移叠加，显示物理移位每Ñ^个投影屏幕上的帧，并且重叠的像素栅格的形式更细的子像素网格具有更高像素数。
