It is a central point of this gadget. The image engine produces an image or video within the projection limit or projector for the display screen. LCD projector uses liquid crystals arranged as individual pixels to recreate color based on an input electronic signal.
The optics are made of series of reflecting mirrors. In the video, projectors optics perform the task of transferring the image from the internal image engine onto a screen for viewing. Internal series of reflecting mirrors and prism reflect and split the light into its component colors. A highly luminous light bulb shines on the completed image via mirrors, and the light then passes through the projector’s lens. It is a projector focus lens that contains several pieces of curved glass, known as an element. These elements bend the light to magnify the image and to control focus.
In every projector mainboard is present. Its behavior is similar to the motherboard of a computer system and it contains several electronic chips and components. The mainboard is responsible to synchronize all internal functions to drive the image engine and allow the user to control the various settings of the projector.
Every electronic gadget has its power supply either with battery backup or alone. LCD projectors need a power supply to process the current traveling to the motherboard and bulb. Projectors with motor-based lenses also use the power supply to drive electric motors that adjust the lens. The power unit may be contained internally or came with a separate power adapter that allows a smaller, lighter, and portable projector design.
Case And Control Panel:
In most projectors, plastic or metallic cases are being used to protect the delicate internal mechanism. The case provides a place to mount the electronic circuits and house the cooling fans. Cases must contain proper ventilation for cool air intake and hot air venting. A projector also contains a control panel that contains several knobs, switches, and mini displays to configure it manually. Some projectors also include an infrared sensing board for receiving IR signals from a remote control.
