Claim Text:
1. A dual-chip light splitting and light combining module, comprising a polarizing light splitting prism, a first mirror, a first polarizing total internal reflection (TIR) prism, a first displaying chip, a second mirror, a second polarizing TIR prism, a second displaying chip and a light combining prism, the polarizing light splitting prism being adapted to split an incident non-polarized light into a first polarized light and a second polarized light perpendicular to each other, wherein: the first polarized light is reflected by the first mirror to the first polarizing TIR prism, reflected by the first TIR prism to the first displaying chip, redirected by the first displaying chip to the first polarizing TIR prism, and then transmitted into the light combining prism via the first polarizing TIR prism; the second polarized light is reflected by the second mirror to the second polarizing TIR prism, reflected by the second TIR prism to the second displaying chip, redirected by the second displaying chip to the second polarizing TIR prism, and then transmitted into the light combining prism via the second polarizing TIR prism; and the light combining prism is adapted to combine the incident first polarized light with the incident second polarized light.
