New LED Backlights For LCD Screens

Posted by timothy on from the you-can-never-have-too-many dept.

Benefits include longer battery life for notebooks, less weight, and a larger color gamut (up to 130% of the NTSC standard). The release can be found here." I wish I could hook up one of their evaluation kits to my machine right now;) The same site has quite a lot of LED-related information throughout.

    That's great. Exactly who is this press release for, anyway?

      The shade of red lipstick you purchased on the Internet and viewed on your LCD monitor will be the exact color red you receive in the mail.

      That would appear to be an actionably false claim. Color calibration can only go so far, especially when dealing with aspects of color that are not captured in current displays such as reflectance, and when mapping between different color gamuts.

      Calibration also gives incorrect results when mapping between different kinds of color. Monitor color is additive, while real-world colors are usually subtractive.

      Finally, color is heavily affected by ambient light conditions, to which monitors and real-world objects respond differently.

      Calibration can reduce differences but it comes nowhere close to removing them.

      The shade of red lipstick you...[noticed] on your LCD monitor...

      It's okay to love your LCD monitor, just don't looooove your LCD monitor...

    Their power-saving plan works by alternating the duty cycle of their red, green, and blue LEDs at 1-65Hz. I can feel a headache coming on already.

      For those who don't feel like building their own flashlight, check out CMG's Infinity Task Light. The LED lasts forever, and it boasts 40+ hours of continuous use on a single AA battery. I use NiMH batteries, which work even longer. The light is bright and rock-steady. I have a blue-green one that is by far the best camping light I've found - whether for reading in a tent or for late-night walks.

  3. Some Canon digicams already use LED backlights by phr1 · · Score: 3, Informative

    The S100/S110 and S300 Digital Elph digicams use white LED backlights. I'm not sure about the bigger models (G1, G2, Pro90IS). I have an S100 and the backlight is great. Good color, and none of the turn-on delay or flickering of fluorescent backlights. The LED's are at the edge of the screen, but the lighting is still pretty even. That may be because it's just a 2" digicam screen. I've been wondering for a while whether it would be a problem for bigger (laptop sized) screens.
