What is the difference between a DLP and an LCD and which one is better?

Answer 1

The Technical Differences between LCD and DLP

LCD (liquid crystal display) projectors usually contain three separate LCD glass panels, one each for red, green, and blue components of the image signal being fed into the projector. As light passes through the LCD panels, individual pixels ("picture elements") can be opened to allow light to pass or closed to block the light, as if each little pixel were fitted with a Venetian blind. This activity modulates the light and produces the image that is projected onto the screen.

DLP ("Digital Light Processing") is a proprietary technology developed by Texas Instruments. It works quite differently than LCD. Instead of having glass panels through which light is passed, the DLP chip is a reflective surface made up of thousands of tiny mirrors. Each mirror represents a single pixel.

In a DLP projector, light from the projector's lamp is directed onto the surface of the DLP chip. The mirrors wobble back and forth, directing light either into the lens path to turn the pixel on, or away from the lens path to turn it off.

In very expensive DLP projectors, there are three separate DLP chips, one each for red, green, and blue. However, in DLP projectors under $20,000, there is only one chip. In order to define color, there is a color wheel that consists of red, green, blue, and sometimes white (clear) filters. This wheel spins between the lamp and the DLP chip and alternates the color of the light hitting the chip from red to green to blue. The mirrors turn on and off based upon how much of each color is required for each pixel at any given moment in time. This activity modulates the light and produces the image that is projected onto the screen.

Answer 2

A DLP uses thousands of tiny mirrors; each reflecting a portion of an image. An LCD uses liquid crystals to form an image. A DLP is superior to an LCD, but the best image is optained with PLASMA.

Answer 3

lcd is a liquid crystal display which uses a different power amount for every hue and texture. If you buy a good brand like Sony, Sharp or Sanyo, then that will surpass any DLP you can buy

Answer 4

i can tell you this , i bought a LCD monitor last year, and a few weeks ago , IT STOPED WORKING. i took it in to the repair shop, they educated me , saying its made up of liquid, when the liquid runs lows, or your out. the monitor no longer works it basically garbage.life span on LCD s are 1 to 4 yrs, not worth it in my eyes , since they can be pricey. i wont buy a LCD until they perfect the product to lasting at least 7 to 8 yrs lifespan. as they mentioned prior to me i was told the same thing, if your going to buy a LCD. make sure its Sony or a well known brand name, it will last yrs longer. good luck

Answer 5

A Digital Light Processer uses a bunch of small mirrors on the inside Liquid Cyrsyal Display is just lick the computer screne if you have one instead of a moniter. to me LCD is better.

Answer 6

dlp is digital,lcd is liquid crystal;lcd s better

Answer 7

can I borrow
2 1/2 (1 ounce) squares unsweetened chocolate
1/2 cup butter
2 cups all-purpose flour
1/2 teaspoon baking soda
1 teaspoon baking powder
1/4 teaspoon salt
1 1/4 cups white sugar
2 eggs
1 teaspoon vanilla extract
2/3 cup sour cream
2 cups semisweet chocolate chips

And then will you
Preheat oven to 375 degrees F (190 degrees C). In the microwave or over a double boiler, melt unsweetened chocolate and butter together, stirring occasionally until smooth. Sift together flour, baking soda, baking powder, and salt; set aside. In a medium bowl, beat sugar, eggs, and vanilla until light. Mix in the chocolate mixture until well blended. Stir in the sifted ingredients alternately with sour cream, then mix in chocolate chips. Drop by rounded tablespoonfuls onto ungreased cookie sheets. Bake for 8 to 10 minutes in the preheated oven. Allow cookies to cool on baking sheet for 5 minutes before transferring to a wire rack to cool completely. Store in an airtight container.

for me? Thanks!

Answer 8

Both have their merits. There are many sites offering comparisons with pros and cons.
