Projectors provide a vibrant visual effect in any environment you place them. They have evolved significantly since their invention in 1895. From what started as a small peep-show box, today we have projector screens measuring up to 300 inches. Now there are numerous variations in the market.
These types range from LCD, DLP and more. Each projector type has its pros and cons. As such, you choose one based on your needs. DLP, for instance, displays crisp images with no filters because the DLP chip comes sealed.
LCD projectors, on the other hand, employ the oldest technology. They come with three panels that represent the three primary colors. This makes them produce clear, detailed images.

LCD Projector Advantages & Disadvantages
LCD projectors are a great choice for displaying videos and images in a home cinema and darkened theaters. They are an enhancement of the traditional overhead projectors and can project clear life-like images.
But, like any other machine, they have their advantages and drawbacks, as seen below.
- Consume less power: they are more light and energy-efficient. Wattage lamps generate brighter images on LCD than on DLP projectors .
- No rainbow effect: you will not see any annoying spattering colors around bright objects as you watch.
- Minimal noise: does not produce audible whimpers.
- Emits less heat: you are less likely to encounter overheating problems with your LCD projector.
- Crispier graphics on data: LCD projectors generate higher-quality graphics than DLP at an equivalent resolution.
- Slight screen door effect on some graphics: these generators produce distinctive pixels, which may trigger pixelation. This is where images look more like animations.
- Image devaluing: the image quality can reduce significantly in case of minimized contrast and an imbalance in color movements.
- Substandard contrast: this happens with the traditional LCD projectors; they cannot generate entirely black graphics.
- Less portable: they have many elements that make them bulkier, thus less transportable.
- Dysfunctional pixels: a pixel may go on or off at the wrong time, thus damaging the image quality.
DLP Projector Advantages & Disadvantages
DLP employs the oldest technology in image projection. It has numerous nanoscopic mirrors that create light or dark pixels depending on the room’s lighting. Below are its advantages and disadvantages.
- Well-polished videos: the videos and pictures are smooth because of the muffled pixel construction that DLP projectors come with.
- Highly reliable: DLP projectors have fewer components, thus less likely to get damaged. This makes them more dependable than their LCD counterparts.
- Highly portable: they are quite small making it easy to carry them around. Some DLP projectors employ a technology that allows them to connect to mobile gadgets.
- High contrast: DLP projectors produce intense ‘blacks’, making them ideal for use in home theaters.
- Sealed imaging chip to avert dust: the chipset is safe from dust particles that may cause damage. The dust could also affect the image quality.
- A slight rainbow effect: it can be disgusting to see traces of rainbow colors on your screen. This happens when using DLP projectors that have a single chip.
- Generates detectable hums: you may find the whims disturbing, especially when watching your favorite programs.
- Light seepage: this may make light deviate and illuminate off the mirrors’ outlines, affecting the final image’s quality.
- Produces more lumens with natural light: DLP projectors may not produce the best quality images in some environments. Projectors require a dark atmosphere where lumen output is low.
How DLP Projectors Work?
DLP has a reflective glass chip that comprises numerous nanoscopic mirrors, unlike other projector technologies. For projections to happen, the projector’s lantern illuminates the DLP chip’s surface directly. The mirrors then keep adjusting as they reflect light toward the lens.
As the microscopic mirrors adjust, they turn the pixel on or off. All this happens at a remarkably high speed of about 16 million cycles in a second. The cycle repeats until comprehensible images form on the screen. The technology employed here is inclined to a proper comprehension of the human eye.
But, the images produced at this stage are in black and white. To give them color, these projectors have three chips; green, red, and blue. A ray of white light is directed toward a whirling color wheel and then to the chip. The final images projected at this point are now colored.
Usually, what you see as distinct images are rhythmic pulsations of red, blue, and green lights. Yes, you may not believe it but if the speed was to be reduced you would be surprised. All you would see are successive red, blue, and green pictures.
When you turn off your projector, the mirrors respond by redirecting light on the opposite direction of the lens. The light is barred from accessing the screen, and so no images will be displayed.
How Does An Lcd Projector Work?
LCD projectors have been around since their invention in the 1980s. Every LCD projector has three glass boards, one red, another green, and the final one blue. They all come with numerous moving pixels that open and close accordingly.
The old LCD projectors manufactured back in the 60s are still largely in use today. These projectors use contrasted mirrors aimed at obstructing and augmenting some colors. This happens in the ‘Red, Green, and Blue’ (RGB) zone.
The modern LCD projectors are slightly different though. To develop the image that you see on the screen, a ray of white light illuminates through the glass boards. Its pixels then unfold and close, blocking or allowing light through. There is also a prism inside the projector that converges the three images into one.
The entire process enables the formation of the beautiful, clear image projected. These projectors employ a wonderful transmissive technology that you will like. It’s especially favorable for environments like darkened theaters and movie houses.
Which One Right For You?
Both DLP and LCD projectors are efficient and very reliable. If you are considering one of the two, analyze their pros and cons first. This will help you decide whatever suits your needs best. LCD gives you unmatched image quality with no rainbow effect.
DLP, on the other hand, offers sharp images and portability for convenience. The main question here is, ‘what are you looking for?’ You will find it easy to select the right projector when you know what you need and what the projectors in question offer.
There are so many aspects to factor in when buying a projector. You may also want a projector you can use in your cinema room and also for presentations. Consider all these beforehand to avoid regrets. All said and done, they are both an ideal fit when bought for the right purpose.
Projectors have come a long way, and they are the best thing to ever happen. Sometimes you want to watch your favorite programs from a clearer and bigger screen than that on your TV. If your cinema room is large and dark enough, you may consider LCD projectors. You can also get it for use in meetings and conferences.
For a relatively small space, a DLP projector will be the best option. It may cost a little more, but the image clarity and high contrast are features worth paying for. You will also enjoy a good prismatic depth. If you want a projector you can move around with, then DLP it is!
