Embodiment Construction
[0054] The main purpose of the present invention is to inject a light source group composed of red (R), green (G) and blue (B) monochromatic light sources from a collimating lens, and guide the light beam into a liquid crystal display through a microlens array. In the color filter, there are dense and regular color points that receive red (R), green (G), and blue (B) light on the color filter, and the color points are aligned with each pixel of the liquid crystal display (Pixel ) represents the three liquid crystal display units of R, G, and B image outputs; and the microlens array has the same number of dense lens units as the total number of pixels (Pixel) on the liquid crystal display and is aligned so that the three colors can respectively penetrate the color The color points of red (R), green (G) and blue (B) on the filter are not absorbed obviously, resulting in a significant increase in transmittance; and it makes the color saturation of the liquid crystal display better...
