[0057] In the MEMS display of the first embodiment of the present invention, the light source is a three primary color light source, such as an RGB three primary color (red, green, blue) light source or a CMY three primary color (cyan, magenta, yellow) light source. Figure 6 It is a schematic diagram of the MEMS display of the first embodiment, including a pixel array area I and a light source II, and the pixel array area I only shows a 4x3 array of pixel units.
[0058] Such as Figure 6 As shown, the MEMS display of this embodiment only includes one input optical path L. When the light beam enters the pixel array area I from the input optical path L, it first needs to pass through the column optical path switching switch. Wherein, each column of pixel units corresponds to a column of optical path switching switches. After the light beam is routed into a certain column of pixel units, it needs to pass through the row light path switching switch in turn, so as to exit from t...

[0064] In the above embodiments, although the light source of the MEMS display can utilize the visual persistence time of the human eye to input the three primary colors of light in time division, the light path structure of the display is simplified. But the scope of application is limited, and there are limitations in the dynamic display of high-speed images.
[0065] Figure 8 It is a schematic diagram of a MEMS display according to the second embodiment of the present invention, including a pixel array area I and a light source II, and the pixel array area I only shows a 4x3 array of pixel units. The light source adopts RGB or CMY three primary color light sources.
[0066] combine Figure 8 as well as Figure 6 As shown, the difference between this embodiment and the first embodiment is that the pixel array area I has three input light paths, including the first incident light path L1, the second incident light path L2 and the third incident light path L3, which are re...

[0071] The MEMS display of the present invention can also be applied to the display of 3D images.
[0072] Figure 9 It is a schematic diagram of a MEMS display according to the third embodiment of the present invention, including a pixel array area I and a light source II, and the pixel array area I only shows a 4×3 array of pixel units. The light source is 3D polarized light. Specifically, the 3D polarized light includes P polarized light and S polarized light.
[0073] combine Figure 9 as well as Figure 8 As shown, the difference between this embodiment and the second embodiment lies only in the number of input light paths. Specifically, the pixel array area has two input optical paths, including a first polarized incident optical path J1 and a second polarized incident optical path J2, which are respectively used to input the above-mentioned P-polarized light and S-polarized light.
[0074] Correspondingly, the pixel units in the pixel array area are divided into a ...
