A projector with a wave length wheel and a color wheel in one module is proposed, the projector comprising: a light source configured to generate a first wavelength band light; a dichroic filter configured to reflect the first wavelength band light irradiated from the light source, and to transmit a second wavelength band light and a third wavelength band light; integrated wavelength conversion wheel and color wheel modules configured to integrally form a wave length wheel and a color wheel each wheel in a parallel manner in order to allow transmitting the first wavelength band light reflected from the dichroic filter and to generate the second wavelength band light and the third wavelength band light through wavelength conversion using the first wavelength band light as an excited light and to reflect the generated second wavelength band light and the third wavelength band light to the dichroic filter; and a light tunnel configured to receive the first wavelength band light reflected from the dichroic filter by transmitting the integrally formed wave length wheel and color wheel, and the second wavelength band light and the third wavelength band light transmit through the dichroic filter by being generated by and reflected from the integrally formed wave length wheel and color wheel.
Description
technical field [0001] Teachings according to exemplary embodiments of the present disclosure generally relate to projectors with a wavelength wheel and a color wheel in one module configured to use a single motor by fabricating the wavelength conversion wheel and the color wheel on a single axis in an integral parallel manner to drive the wavelength conversion wheel and the color wheel, where each wheel is separated from the other. Background technique [0002] With the rapid development of the information age, the importance of a display device capable of realizing a large screen has been emphasized. An example capable of realizing a large screen may be a projector having a function of transmitting images in an enlarged manner. [0003] A projector is a projection device configured to display a large-sized image by enlarging a small image realized on a small-sized display formed therein, and to transmit the enlarged image on a large-sized screen using a transmissive lens....
