DLP vs LCD Televisions
When choosing a high-definition television consumers are often faced with the choice of a DLP vs LCD set. A newcomer to the television market can easily become overwhelmed by this prospect. There are several factors for you to consider during your decision to choose between a DLP vs LCD television including price, performance and overall display quality.
An LCD TV screen, standing for Liquid Crystal Display, operates by illuminating millions of red, green or blue liquid crystals that change turn off and on to produce the proper color on your screen. Why red, green and blue you ask? These are the primary colors of light that make the visible color spectrum as we know it. LCD televisions tend to be very bright, making them ideal for a well lit room in your home as external light will not likely cause many issues with glare.
Most LCD televisions are between 2 and 4 inches in depth, which is ideal for wall mounting your television. Unfortunately, LCD screens are rarely seen in models greater than 50 inches in diameter due to the difficulty in producing large LCD displays in a cost effective manner. One common criticism regarding LCD televisions is that over time, typically 70,000 – 80,000 viewing hours, the green crystals will begin to fade, causing a red-blue tint to the screen. There is currently no option to fix this issue without replacing the television. Many 720i – 1080i LCD televisions below 40 inches in diameter can be purchased in the $300 – $800 price range, which gives the LCD display an initial cost effective advantage in the DLP vs LCD dilemma.
A DLP TV (Digital Light Processing) operates by reflecting light onto a microchip covered in thousands of small mirrors. These mirrors send the reflected light through a color wheel which then projects the correct color onto the screen, similar in fashion to rear projection televisions of the past. This technology is often put to use in digital projection movie theaters to enhance the picture color and clarity.
Although typically more expensive, DLP televisions do not suffer from the green crystal degradation that is common in cheaper LCD televisions. In addition to this, DLP television bulbs are replaceable for approximately $250, a much more reasonable replacement cost than the upper end LCD televisions. While the DLP televisions can produce a much more vivid picture and boasts an extended life span compared to LCD models, some people report a "rainbow effect" if they are too far off from the center of the television. Another issue to consider in the DLP vs LCD debate is the size of the DLP televisions. DLP sets range between 6 and 16 inches, making them more obtrusive and difficult to wall mount than their LCD competitors.
DLP vs LCD Conclusion
When considering your next television purchase keep these pros and cons in mind as a guideline when deciding whether to get a DLP or LCD television. When in doubt about the DLP vs LCD dilemma you can always view both types of TVs in similar lighting conditions in the room you tend to display it in to help you to make a decision.

Is LCD rear projection the same thing as DLP? What makes Lcd Projection different or better?
Looking to buy a new tv, but want one that won't die or be obsolete in 5 years. I've heard repairs on DLP are cheaper than most.
LCD Rear Projection is not the Same as DLP.
DLPs use technology created by Texas Instruments.
Check out http://www.DLP.com for specifics.
LCD Rear Projection check out Sony's models for a good screen.
http://www.sonystyle.com/webapp/wcs/stores/servlet/CategoryDisplay?catalogId=10551&storeId=10151&langId=-1&categoryId=564
If you're looking at a 1080P set, the DLP's use something called Wobulation that produces the 1080P picture. Basically it flashes have the pixels in 1/60th of second, and the other half the next 60th of a second. Tricking your eyes to thinking that you're watching 1080P. I know some people have problems with this, their eyes / brain catch it and it gives them a headache or something called the Rainbow affect.
With LCD Rear Projection you're actually seeing 1920x1080 pixels at the same time. So its a better picture.
JVC also makes a nice Rear Projection TV. You should check out.
Both of these technologies will probably be obsolete in 5 years as things like OLED and SED come out.

LCD Ultra Narrow LCD will dominate the large-screen mosaic market
Meeting in a large monitor or high-end projects, if you need a large view screen, splicing technology to imperative. Large screen display system here the core of large-screen display device and screen display unit to be a brief overview:
A large-screen display processor
People in the industry know: the program of choice when a large-screen display, but not the line of people think of first is to choose the display, while the first choice of people who know the business splicing processor. Determine how much of a bucket can hold water is the shortest piece of wood. Splicing programs as a core component of the current processor is one of the shortest splice piece of wood! Splicing can also be said that a large-screen display system processor is the heart or soul! It determines the large-screen display system display and stitching!
Over the years, large-screen display technology can be divided into two main schools: a card-based industrial computer programs, also known as "soft stitching"; one is based on the structure of the embedded FPGA array program, also known as "recklessly pick . "
"Soft stitching" to DATAPATH card represented a long time because of their applications, together with the operating system running on the computer, so very rich variety of applications. As the DIY solution to meet the requirements of our customers, so many businesses can be launched in a short time, "his" splicing processors, so sought after by many businesses!
But as customer requirements continue to increase splicing, in addition to roaming outside the window stack, multi-dynamic images, high-definition video have a customer set up the basic indicators of a large mosaic wall.
In this trend, the "soft stitching" the soft underbelly of gradually stand out: the current market "soft stitching" can not display multiple dynamic VGA screen, let alone a multi-channel high-definition images.
Many people think: the current "soft stitching" technology development is difficult, mainly due to the motherboard and CPU processing power acquisition bandwidth bottleneck caused by two, as long as the solution of the two bottlenecks, the technology will be rapid development.
The industrial organization framework of the "soft stitching" is through the PCI-channel signal acquisition, and the standard PCI bus bandwidth is 133M, the bandwidth of the signal in the face of multiple or high-definition signal, appears to do nothing; some companies in order to address this bottleneck, to compress the graphics signal processing and then extract the way, but the graphic quality of the signal compression that seriously affected. Some companies now use the jumper the way, the bandwidth will be expanded to 500M or so collected, more mature and stable industry companies simply put aside the PCI bus architecture, the other channels designed to enhance the bandwidth of graphics board, and some called the bandwidth of up to 2G, 4G or even Hundreds G! Insiders said with a smile: China's audio and video industry might affect the next generation of computer motherboards architecture, the traditional PCI bus will be eliminated!
Regardless of whether these programs mature, but even if the acquisition bandwidth can really be reliable and stable solution, but the industrial sector of the processor performance aircraft, like the performance of a computer like the motherboard is only a threshold constraints on their performance, as well as CPU, GPU and memory, etc., affect the overall performance of IPC. So even if the Board issues can be resolved acquisition bandwidth, the current CPU and GPU processing power but is limited! Overall performance of the components in the computer can greatly enhance the environment, currently on the market "soft stitching" program results are Nanjinrenyi!
In this context, the "soft stitching" suppliers often evasive in front of the customer asked: when customers need high-definition signals, suppliers often speak a lot promise; however, they can only provide the base map definition, or can only provide static Dynamic HD signals or HD signals all the way!
If a large mosaic on the wall can not use multiple high-definition motion picture, is clearly not a forward-looking stitching system! And soft-splicing system crashes, the crash risk is also growing. "Soft stitching" more and more serious flaw of instability, and the operating system is easily the virus can also allow users to take the heart of the problems!
With the "soft stitching" technology has become more apparent weakness of the domestic science and technology in the sun, represented by "recklessly pick" is a meteoric rise, then the characteristics of recklessly make up the "soft stitching" the lack of: stable, fast response, boot can work a few seconds to collect the high channel bandwidth to support multiple dynamic images, there is no operating system, so no worries poisoning. Soon the technology is an advanced modular design concept will be spliced into the processor, so that equipment maintenance is more efficient and convenient, making the industry with admiration.
But: Soft splicing applications recklessly take advantage of feature-rich it is hard to do: For example, aspects of soft-splicing can be to provide high-resolution base map that can support network screenshots, you can achieve centralized or distributed network management, etc., are hard splicing temporarily can not do!
There is competition, there is progress in the splicing program of any company in order to win in this race, we must have recklessly take powerful performance, but also must have a mosaic rich application software and powerful management features. In the end who can stand out in this competition it? I believe the industry are looking forward to.
Second, the screen display technology
At present a large-screen display using the display unit are DLP rear projection, plasma displays, LCD displays three. Display unit in the following table for the key technical indicators to be a simple explanation:
Performance
LCD rear projection, plasma indicators Conclusion / Remarks
Brightness 500 ~ 1500/m2 intermediate ≤ 500cd/m2
Corners ≤ 250 ~ 300cd/m2640 ~ 1000cd/m2 brightness and contrast are inseparable, two key indicators in this, plasma seems better skill, this is due to the plasma all white all black due to measurement method, according to the American National Standards ANSI to measure, plasma and LCD contrast to almost, this calculation method is shown with a black and white images were compared.
Resolution above 1366X768 resolution determines the clarity of 1024X768854X480 in this indicator, the LCD has an unparalleled advantage.
Power 200W/40 "and other large-size LCD units 300W ~ 500W / unit 500W/42" LCD energy consumption is only one-third to one quarter the other, this indicator was a huge advantage LCD.
60,000 hours backlight life of one thousand hours is necessary to change a light bulb 5-8 still high brightness 5000 hours, the dynamic Projection Screen 10,000 hours life can not be compared with LCD and plasma, and LCD compared to plasma, in life also have a huge advantage , by replacing the LCD backlight can extend the life of a substantial color plasma faded images can only be the occasion of renewal, there is no other way.
Color saturation is generally 72%, while the screen is 95% lower DID 90% of capacity on the performance of color, comparable to plasma and LCD.
Burns burns burns the static picture will not burn a serious time when the still images appear in the same location on the plasma screen, it will burn the phenomenon occurs. When the switch, the screen will dim the image goes to play there for a long time, as if the same imprint on the screen.
Large volume thin thin LCD and plasma flat panel display belong to, are very thin.
Display unit composed of three splicing systems have advantages and disadvantages:
DLP rear projection splicing mainly Vtron currently represented, as well as the Delta-CIMIC, in TV News, On ratio, Jiuding and some other company is also a professional supplier of DLP splicing.
DLP compared to the advantages of the other two in its patchwork mosaic of small, operation and maintenance simple. But its shortcomings are obvious: For example, excessive size and weight, the key technical indicators are far less than LCD and plasma, its biggest flaw is the high running costs: long uninterrupted work and DLP rear projection lamp will speed up the aging rate , rear only a few thousand hours of bulb life, and if twenty-four hours to run, a few months will need to replace the projection lamp, the user is not a small operating expenses.
PDP plasma splicing Orion's MPDP currently represented by South Korea, because other normal plasma splicing is rare in the market, so there is not as described.
Orion's MPDP because of its patchwork of small, thin, and access to many customers of all ages. But its shortcomings are intolerable: in addition to a large power consumption and heat, as well as severe burns, and does not fit monitor screen for a long time to display static environment. But also for stitching, the machine temperature rise even higher, leading to equipment easy to burn. The resolution also makes many users criticized: only 854 × 480, even lower than the computer graphics card driver is not installed when the 800 × 600, close watch is almost unbearable.
LCD Samsung LCD splicing the DID currently represented, although the stitching on the market also SHARP, LG, NEC and other brands, domestic innovation and competition Wei Pu, but its excellent value for money DID Lcd Flat-panel stitching technology in the thriving, its thickness thin, light weight, low power consumption, Long Life, no radiation, etc., and its delicate screen, high resolution, the excellent performance of key performance indicators, has made it into the mainstream of development, prospects.
As a mosaic display terminal, LCD Despite these advantages, but as a mosaic display unit, the drawback is fatal: it is the current patchwork of its large, integrated patchwork to 5.5MM, splicing in the three largest display unit, so that Many users had to reluctantly give up.
Basically do not burn
Analysis: When the burns showed the phenomenon still image stays in one place after a long time, it will leave a shadow on the screen. Principle of liquid crystal display projector screen will not determine the burn, but the plasma burn is severe, This is the principle by the plasma gas caused by light.
Thick and thin thin volume
Analysis: plasma and LCD flat panel display belong to a thickness small.
Welds smaller
Analysis: part of the LCD backlight LCD screen side of spliced lead to a certain gap, the use of LED backlighting, the patchwork and rear projection LCD, plasma very.
Although the LCD has such serious flaws splicing, but splicing unit was pinned LCD large-screen display of all persons in the industry expectations, large-screen display system, after all, the trend is already apparent: that is unlimited in the mosaic on the wall show more Way high-definition motion picture! One display unit in order to further the development of high-definition, fine patchwork, low power consumption is the development direction of light; and three display units, only the LCD to take on this task. Samsung has launched the current patchwork to 5.5MM splicing integrated screen, the official listing just around the corner. This major breakthrough has been spliced to MPDP and DLP huge impact, MPDP and DLP in order to survive, does not significantly improve the technical performance of the premise, only a substantial price response.
Perhaps as a response to this technological trend, the recent domestic security industry manufacturers in the acquisition of security giant LCD display technology at the core of the ring after the stone, but it has abandoned its development and growth in the domestic Jiuding division, which is to back investment as the core technology products.
Samsung even said the ambitious: to introduce in the coming year, as small as two millimeters patchwork mosaic within the display unit. If this program really be achieved, stitching industry, separatism will be completely rewritten, PDP and DLP market exit from the stitching, LCD splicing will dominate the world.
