Questions from a Technology Challenged

Wuts an LCD and an LED?

And wuts ultrabay slim?

thanks.

 

okay lets start with the basics..an LCD stands for liquid crystal display..which can be lets say a monitor on a computer or a LCD tv like you see in stores. an LED is ..wel wait wait wait..instead of me trying to type this all out because its 12:30 pm and i really need to get some sleep just go to a search engine and look or something..

 

lcd is basically the thing that produces an image on your screen. An led is a new way of lighting that image so that it is bright for you to see that is power efficent compared to a bulb.

 

They are two different types of flat panel screens. LED screens are a lot newer than LCD screens. LED screens are thinner, brighter, and consume less power than LCD screens...but are also more expensive. The laptop screen is the most expensive parts of a laptop and LED screens are found on the top of the line 14" or less notebooks.

 

uhm...those led powered screens are lcds. its just that the bulb is usually more power hungry so a more premium feature in more expensive notebooks. They are the same screen without the lighting.

 

LCD = Liquid Crystal Display. The first ones (simple black and white) came out in the 1970s and the technology has evolved since then.

LED = Light Emitting Diode. They are like mini solid-state light bulbs and are getting more and more common. They are also efficient in producing light. Coloured ones have been around for some time but ones which produce acceptably white light are very recent (and more expensive).

Most LCDs in notebooks use a small fluorescent tube as a backlight. Getting the light from the tube to give even illumination of the panel is a technical challenge.

LED backlights for notebook displays are very recent. They are more efficient in creating light so give the opportunity for brighter displays and/or less power consumption. They also take up less space so the displays can be thinner. And, at present, they cost more.

The ultrabay is the Thinkpad's name for the standard multi-bay that's on business-line machines and a few others (others call it the multibay, or smart bay, or whatever).
It basically is where the optical drive sits - but can be removed and replaced with either an empty drawer (to reduce weight for travel), an extra battery, a media/floppy disk drive, or an extra HDD. Typically, the machine comes with the optical drive only, although sometimes they'll add an empty traveler's drawer or even an extra battery for free depending on the retailer.

 

John Ratsey and taelrak got it right. Don't listen to the rest.

 

LOL that kinda means the OP shouldnt listen to you either fabarati cuz you are one of the rest too this then potentially causes a loop in events.....

 

It would, if it wasn't for that fact that i'm always right. Since I'm never wrong, the world is at times.

 

but u said dont listen to the rest, you are one of the rest therefore if only john and taelrak are right, then you got it wrong. that kinda puts u in a bind, you are never wrong yet you have indirectly stated as such, therefore you could also be wrong about them being right or could you be right about being wrong? see the confusion u have caused

 

To be hones when I said the rest I mean the Rest except for me (cause i'm the one giving advice), John Ratsey and taelrak (cause they knew what they were talking about). I almost always include myself.

 

LCD stands of Liquid Crystal Display, and is a type of display, used in literally all notebooks, for about the last 2 decades. A liquid crystal layer is sandwiched between two panes of glass I believe. and light shines through filters in the liquid crystal, producing of pixels of different colours at certain given moments.

An LED is a light emitting diode, a part in an electric circuit that only allows current to flow in one particular direction, and gives out light when a current flows through it. So, current is passed though LEDs which produce the source of light for the LCD image production mechanism.
