Overview
- Digital Projectors have been an indispensable part of every educational institute, auditorium, seminar hall, conference room, and office for decades. Existing in a variety of forms, digital projectors are used for multiple purposes ranging from conducting classroom lessons, conferences, meetings, seminars and even for infotainment at times.
- So Today we will mainly talk about the differences between DLP Projector and LCD Projector. For your reference!
An LCD projector is a type of projector based on liquid crystal displays which can display images, data or video. An LCD
projector works on transmissive technology. LCD projectors are more popular than many alternatives due to the fact that
they are cheaper to produce and have excellent color reproduction. They are commonly used in business meetings,
presentations and seminars.
How it LCD Projetor Works?
The light source for an LCD projector is a standard lamp. An LCD projector allows the source light to pass through the
three colored liquid crystal display light panels. The panels in turn allow some colors to pass through and block some
colors to form the images on the screen.
DLP stands for Digital Light Processing Projector which makes use of tiny mirrors that reflect light towards the screen.
The setup includes a physical colour wheel that spins to generate sequential colours. DLP projectors can be single-chip
or three-chip with red, green and blue DLP chips.
How it DLP Projector Works?
LCD Projectors use three liquid crystal displays, in which an image is created through multiple steps. A light source emits
a beam of white light which is passed to three mirrors which are specially shaped to reflect only particular wavelengths of
light. Each coloured light beam is sent to an LCD panel, which receives an electrical signal. The signal commands the panel
on how to arrange the pixels in the display to create the image. The same image is produced on the three LCD panels,
but in different colours due to the source light falling on them. These different coloured images are then combined in a prism
resulting in a single coloured image. Finally, the image goes through a lens before reflecting on the projection screen.
| LCD Projector (Liquid Crystal Display) | DLP (Digital Light Processing) | |
| Advantagaes | *Richer color dynamics in ambient light *Less power *Throw less heat *No "rainbow effect" *Quieter, sharper image on data | *Smoother video *Smaller box *Pixels less visible *“Filmlike” on HDTV *Generate "blacker" blacks *Higher contrast *Portable |
| Disadvantages | *More visible pixels *Some screen door effect on certain video images *Larger - even for same lumen # *Poorer contrast *Black is lighter gray than in DLP | *Some "rainbow effect" *More moving parts *Produce audible whine *Poorer reds, yellows at full power *Color saturation *More lumens than LCD with ambient light |
| Image | Sharper image; better picture quality than DLP projectors | Good picture quality, but poorer than LCD projectors |
| Portability | Not very convenient for portability | Smaller, Lighter, Easily portable |
| Light Source | Standard Lamp | LED or Standard Lamp |
| Year Invented | 1968 | 1987 |
| Price | $200 - $1000+ | $300 - $1000+ |
