DLP Vs LCD? Which one is better?
If you are looking for a projector to facilitate you in watching movies or enjoying party sessions with family and friends in the home, you might be in trouble in deciding the type of projector you buy. There are several DLP and LCD projectors in the market. Although there are several brands in the market, some basic things are common in every DLD projector and every LCD projector. You need to know the differences between these two technologies and figure out the one which may suit you based on your preferences and budget.
In this discussion, you will find some basics of these two technologies, features, and advantages and disadvantages . We have tried to identify the subject matters for differentiating these two based on their operations, light source, technology, image quality, connectivity, portability and other important issues.
Before going to the deep discussion on the issue, we have to know the basics of the two projectors and their features.
An LCD projector is a device that uses the technology of Liquid Crystal Display and contains three separate glass panels which are red, green, and blue. This type of projector was invented in 1968. It uses the transmissivity technology and light source is a very standard lamp. There are two types of LCD projectors, namely single-chip LCD projector and three-chip multiple projectors. LCD projectors have the following features:
DLP projector, invented in 1987, uses the reflective technology to project the content in the screen. It stands for Digital Light Processing which beams light through a color wheel, reflection mirrors and lens. The light source of the DLP projector is LED or standard lamp. Its operation is mainly based on the Digital Micro-Mirror Device (DMD) which are millions in number in a projector. DLP projectors possess the following features:
Pros of DLP Projector & LCD Projector:
DLP projectors have a better contrast ratio than that of LCD. Besides, these projectors are small in size so that it is easy to carry if the projector is of one chip rather than multiple chips. You can view from a normal viewing distance due to its muted pixel structure. These projectors have fewer parts and connectivity to a smartphone, tablets, laptops, PCs, and other devices. It possesses easy setup and minimized installation and repair cost. Besides these, DLP projectors possess some advantages like smooth video session, the creation of blacker blacks, the projection of HD resolution.
On the other hand, LCD projectors also have advantages that make these popular around the world. LCD projector offers superior image quality thanks to its color accuracy and sharp image quality. It does not have color wheel so that color saturation remains accurate throughout the session. Besides, LCD projectors are lighter efficient than that of DLP projectors. LCD projectors possess rich color dynamics in ambient light, consume a smaller amount of power, create a reduced amount of heat and noise etc.
Cons of DLP Projector & LCD Projector:
DLP projectors have several drawbacks with regard to the rainbow effect and light leakage. The rainbow effect may hamper the health condition of some viewers. Grey band outside of the image can cause abandoned light reflecting off the edges of the mirrors on DLP chip. However, this light leakage can be avoided by mounting additional black borders around the projector screen.
LCD projectors also have some limitations. One of the limitations is the contrast ratio since LCD contrast cannot yield completely black images in some models. Also, some parts of LCD projectors are large and thus turn into less portable than DLP projectors. There is pixel interference with the image quality and the experience since one or more pixels turn off or on eternally. Another limitation is the image quality degradation.
Differences between these two are described under the following heads:
DLP projector’s operation basically based on a chip, namely Digital Micro-Mirror Device (DMD). Each DMD consists of miniature mirrors that are two million in numbers, each of which can move to source or move away from the light source for facilitating pixels that are bright or black. With a three-chip architecture, this projector is able to deliver trillions of colors at a time. It is used in home theater and large venue projectors. The image projected to the screen is shaped by light shining, combined, and directed though the lens.
On the other hand, an LCD light is projected into mirrors that split into three colors namely red, green, and blue. These colors then pass through the three separate prisms. LCD projectors incorporates LCD technology system to make pictures in the projector. The picture is made by following a multiple step process. The source of the light delivers a ray of bright light which passes to three mirror which are specially shaped. These glasses reproduce the above-mentioned colors. LCD panel receives an electronic signal which inculcates to arrange the pixel to generate the pictures. The images form in the prism which facilitates one final picture. This image then passes from side to side of the lens for projecting the contents in the screen.
An LCD projector has LCD panel which allows light to pass through the liquid. There are three LCD panels in LCD projectors which are not reflective like DLP projectors.
On the other hand, DLP technology means Digital Light Processing that uses tiny mirrors in order to reflect light towards or away from the screen. It is reflective. In DLP projectors, light is reproduced using the micro mirror device. There can be a single-chip DLP projector or multiple chip projector. In the case of first projector, light that is generated from the lamp moves through a wheel and crosses the original lens. Then the light reproduces in a mirror which is appeared in the front. In this mirror, the light spreads onto the main DMD.
3. Light source:
The light source of the DLP technology is quite skeptical which can use different types of light source. However, the light source is disposable and can be replaced. DLP projectors which are extremely small. This projector also uses LED light or lasers.
On the other hand, metal-halide lamps are used in LCD projectors in order to provide ideal color temperature and a broad spectrum of color. The LCD projectors small and portable because of its small lamp.
4. Image quality:
DLP projectors offer great image quality but it is less great compared to the LCD projectors. On the other hand, LCD projectors offer sharp images and quality pictures than that of DLP projectors offer. You will find the screen door effect in earlier generation LCD projectors. However, the situation is improved and updated in the new generation LCD projectors. On the other hand, DLP projectors are thought to project a smoother image quality as well as video images.
One of the most significant issues while looking for the great picture quality is the contrast ratio of the device. It measures how much realistic a picture looks like. LCD projector comes with the higher contrast ratio and excellent image quality while projecting the content in the screen, whereas DLP projectors possess a lower contrast ratio than that of LCD projectors.
6. Rainbow effect:
DLP projectors have a rainbow effect. On the other hand, LCD projectors do not possess rainbow effect. DLP projectors, with its rainbow effect, can create an image using sequential color. There is just one color in any given fraction of second and it is done so fast that the human brain can combine it into a full-color image easily.
7. Motion blur:
It means softening of a moving image. DLP projectors will facilitate you with sharper images during fast motion although it has poor contrast ratio compared to LCD projectors. On the other hand, motion blur is still a problematic issue which may not suffer the user due to the high contrast ratio and excellent image quality.
DLP projector is the type of projector that uses the technology like digital micro mirror device. These projectors are smaller in size, lighter in weight, and thus possess the feature of portability. On the other hand, LCD projectors are the type of projectors which are bulkier in size and thus do not possess the portability feature like DLPs.
DLP projectors have the feature of low maintenance cost over the LCD projectors. The reasons are that these projectors have filter free and sealer chipset design.
LCD projectors produce a smoother image with a great level of brightness. On the other hand, DLP projectors also offer brightness but as much as LCD technology.
Hopefully, you have already come to know the differences between the DLP vs LCD projectors by. Now, you can choose one as per your preferences. Good luck!
