Abstract: The optical machine module includes a light emitting module and a modulation module. The light emitting module includes a light source configured to emit linearly polarized light. The modulation module includes a modulation component. The modulation component includes a light-combining prism and a liquid crystal on silicon (LCOS) modulator. The light-combining prism includes four rectangular prisms. The light-combining prism has four sides and four intersection planes formed by the four rectangular prisms. The LCOS modulator includes a first LCOS modulator, a second LCOS modulator, and a third LCOS modulator. The first LCOS modulator, the second LCOS modulator, and the third LCOS modulator are respectively disposed on light emitting sides of three different sides. At least two of the four intersection planes are configured to split light. At least two of the four intersection planes are configured to combine light.

Abstract: This application provides a display screen, a display screen protective film, and an electronic device. A transmissive layer of the display screen has a first surface away from a display panel, an orthographic projection of each micro structural unit on the first surface and along a thickness direction is located in a pixel region, and a projection area of the micro structural unit is less than or equal to an area of the pixel region. The micro structural unit may be a curved surface. In this embodiment of this application, the pixel region may include a region in which a sub-pixel is located on the display panel, and a spaced region between the sub-pixel and another sub-pixel that is located around the sub-pixel and adjacent to the sub-pixel. In the foregoing display screen, each micro structural unit mainly bends a display light ray of one sub-pixel. This helps reduce a difference in light refraction degrees between different sub-pixels, and further helps optimize a flash point.
