DS001AKA
Explanation of Basic Operation
• Apply DC 300V to the lamp driver.
• Light emitted by the lamp is focused by an elliptical reflector on a glass rod integrator, and is rendered
homogeneous at the output end of the integrator.
• Light output from the integrator passes through a relay lens and collimator lens to become a collimated ray,
which is color-separated by a group of dichroic mirrors.
• The color-separated rays are focused on the respective RGB dots by microlenses mounted on the
LCX011AM, and distributed.
• After transmitting the panel, the light is enlarged and projected onto a screen by a projection lens.
For details of the LCD panel operation, please refer to the LCX011AM specifications.
