Which is Better: DLP or LCD?

DLP and LCD televisions are very different. Where one takes up relatively little space (LCD), the other can be quite a bit larger due to needing a big enough space to separate a single bulb from the screen itself. DLP televisions aren’t currently as prevalent as LCD, though the technology is widely used in digital projectors. So, which is better: DLP or LCD?

Digital Light Processing (DLP)

Which is Better: DLP or LCD?Developed by Texas Instruments, digital light processing is a technology that uses a single light source that passes light through a series of mirrors linked to a microprocessing chip. As the light passes through, the mirrors are directed at various colors to create the image. This image is then projected to a screen. In the cases of televisions, this screen is a part of the television itself.

One of the clear advantages to DLP technology in televisions is the longevity of the device. The image is created through use of a single bulb which can be replaced relatively easily. This means that once the bulb has expired, a replacement will restore the set to the same clear working order that it had the first day it arrived in the home.

DLP televisions don’t have as wide of a viewing angle as their LCD counterparts. Typically, you have to position your furniture directly in front of the television in order for everyone present to see a crisp, clear image.

A DLP projector (or television) will also maintain crisper colors and saturation levels long into its life cycle.

Liquid Crystal Display (LCD)

A liquid crystal display is thinner and lighter than its DLP counterparts. The screen itself can produce crisp, vibrant colors and uses less energy than DLP to do so. At its current state, LCD (and LED-LCD) technologies are currently seen as the predominantly used system for high-definition televisions.

One of the big advantages for LCD technology is the overall brightness and wider viewing angle of the screen. This allows LCD displays to be positioned in various different ways around the room without ruining the viewing experience. They can also be easily mounted on the walls due to their lighter weight and thinner overall frame.

An LCD projector or television also doesn’t have the rainbow effect, which creates the illusion of different colors of light shooting across the screen as viewers turn their heads to the side and back. This effect is caused by the spinning color wheel needed to add color to the light moving through the mirrors.

Over all, both technologies hold their own in the world of projectors. DLP allows for longer use with minimal loss of color or contrast over years while LCD gives a wider viewing angle and a smaller footprint. Which of these technologies is right for you?

  • Your explaining technique is impressive Kelly, I liked it. Thanks for the info.

  • I guess the changes are because they are trying things out. I gather that, because it is a beta, meaning not yet a final product. Glad to see your points, but juding by the changes that came every two weeks in Lion testing, and the fact that we are likely 8 weeks or so from it launching, I am sure some of these issues, if not all, will be addressed.

  • Agreed. I really don’t see the point in commenting on beta software.

  • There’d better be a way to turn off having it show the details in the lock screen or else the privacy issues are rather severe (!)

  • iOS 5 is a beta, and it’s under NDA. The correct place to voice these concerns is directly to Apple, not in public. It is not a finished product. You are misleading people to report on iOS 5 in its current state as anything could change before release.

    If you want to be helpful, report your concerns at http://bugreport.apple.com and don’t violate your NDA (or don’t aid and abet others in violating their NDA).

    • Wait. Apple has put software that violates patents under a NDA?

      Well I suppose that is actually logical… Since you know… Google should sue the life out of Apple for these. God knows Apple would, and their patents are almost never valid.

      Maybe Apple thinks that if they mess up the notifications enough Google won’t care?

  • While I mostly agree with the points made here, it feels a bit premature? I think commentary like this is important, and belongs in the hands of the Apple devs making changes to the beta every version. But to call notifications in iOS 5 a total mess, when it’s not officially done?

  • Is this something that would get fixed through updates to the apps themselves?

    It seems like on Android, app developers anticipate the notification bar and program it in, compared to developers of iOS who, til now have not had to worry about it.

  • I personally think this article serves a useful function. It is interesting to see the development of iOS and who know’s, maybe someone up there is paying attention.

    • They pay more attention to bug reports, and anyone with beta access can make them. Apple has done a very good job at addressing bugs and feature requests. I just recently started developing on iOS and I’ve been very impressed with their developer support.

  • This is why you jailbreak and use tons of available tools.

  • I love my iPhone 4 yet I miss many of the UX and UI features of WebOS on my Pre. The notifications were useful and easy to interact with in most cases.

  • Please stop, I’m tired of seeing articles treating current iterations of the beta as final. This is all subject to change and they’ve been tweaking it a great deal, as pointed out with the change in lockscreen notifications from b1 to b2. We still have a long way to go until the fall release. If you do have access to the beta and see something that could be improved, then I urge you to report it to bugreport.apple.com. Also, some notification behavior can’t be helped until Apple starts accepting 5.0 app submissions as some notification behavior is decided on how they are programmed into a specific app. I know you’re just trying to provide some good content, but now is not the time to be overly-critical of iOS 5 as it’s still a work in progress.

  • iOS 5 is not finished yet. That’s why it’s called a BETA. It is for specific people – developers – not for bloggers and for devices you actually use right now. If you’re not satisfied, talk to Apple, but don’t influence people.

    As a side note, there are icons next to the notifications.

  • I bought a DLP a few years ago and had nothing but problems. About a month after getting it the lamp went out and it took 2 weeks for a repairman to replace it. It never worked properly and I was told to bad so sad. It quit working again about a year in and was told it couldn’t be fixed. I had insurance on it and received a check for the full price. I could not recommend this product ever.
