    LCDs take very little current - microamps.
    LEDs take more current - milliamps.
    LCDs are not bright. They depend on reflected light or back lighting.
    LEDs are bright.

    Is is safe to assume you are referring to the televisions that market themselves as LED or LCD tvs?

    Watch out ... it seems as if some TV manufacturers are marking their TVs as LED when they really mean LCD with LED backlight.

    Important keyword: Look for OLED, which means the display emits light to make the colors, like a plasma display. Organic LED, they are printed on film similar to the way LCD are, but cost much more.

    Right now only phone and some notebooks have OLED displays, you can tell by being able to read them in full sunlight.

    "LED" TVs simply mean the backlight has been changed to LEDs, rather than florescent tubes. The display is still shown via LCD.

    Yep. But not everyone knows that. Some people think that an "LED" TV is different than an "LCD" TV. Its good marketing by the TV manufacturers, but not entirely ethical, in my opinion, to mark them this way knowing that it implies something that will confuse people.

    aye, well practically all 'LED' tvs are just LCD with LED back lighting,

    authentic OLED or the like sets are not common.

    All the cell phones I have seen have a backlighted LCD display that cannot be seen in daylight or sunlight. I would like to see one that can be seen in daylight and sunlight.
    I have seen advertising screens with extremely bright LEDs that can be seen in sunlight and they are dimmed at night and on coludy days.

    Are the OLED screens on new cell phones dimmed when the ambient light is not bright?

    Sir,
    all the cellphones ( Maximum ) LCD's are equipped with the LDR on the LCD panel it self and the function of Light and Dark is controlled with it

    The Motorola Droid Razr, and I think the Samsung S3 use OLED displays. There are some very bright LCD screens around, but they suffer a lot with black levels being grey.

    OLED notebooks are now in production but the price tag is scary, and the size isn't > 17", usually 16".
