So, we’ve got HDTV and LCD’s and plasma and CRT’s and NTSC. All those are going to be old news soon, and OLED’s will take over! What is OLED? OLED stands for Organic Light Emitting Diode and is a new twist on an old technology.
LED’s or light emitting diodes have been around for decades. Originally conceived in the mid 1920’s, it wasn’t until the early 1960’s that much was done to advance the LED technology. However, by the late 1970’s, LED’s were becoming very popular. Texas Instruments used them in calculators and watches, and other manufacturers soon followed suit. However, LED’s had a tendency to eat batteries, so LCD technology with a much less power hungry back light became the standard.
With the advent of large LCD panels in the 1980’s and 1990’s, TV technology was applied and the first thin panel HDTV and widescreen TV’s came out. Granted, the picture quality wasn’t quite as good as a CRT or Cathode Ray Tube TV, but the savings in size was critical in some cases. As production ramped up, the price per panel for LCD TV’s dropped, and in the early 2000’s, Wal-Mart was able to begin selling large screen LCD TV’s for under $1000.
But LCD’s have one large disadvantage. The usual viewing angle is less than 150 degrees, which means that unless you’re sitting directly in front of it, you lose image quality, and if you’re sitting far enough off to the side, you can’t even see the image at all!
OLED’s will change all that! Cheaper to manufacture than LCD panels, and with some unique characteristics, OLED’s will replace both plasma and LCD panels within a few short years. Since each OLED ‘pixel’ or ‘picture element’ is lit, instead of being back lit like an LCD panel, this means that there is no loss of viewing angle, even when you approach 180 degrees.
And OLED screens have another major advantage over its LCD counterpart. It is flexible. LCD panels are crystals embedded in a liquid substrate and have to remain in a rigid frame in order to work properly. OLED’s can be embedded in a plastic polymer sheet with a thin film circuit sheet fused to it. This means that instead of a rigid LCD panel about an inch thick, you have an OLED screen just a few millimeters thick.
This means that an OLED screen can be rolled up, or applied to a wall like wall paper, or formed around curves or corners to create totally unique viewing areas not limited to the capabilities of the LCD panel. Imagine being able to push a button and your OLED screen will unroll out of a hanging unit, providing you with brilliant, HDTV color and brilliance, with a quality that can’t be matched by either plasma or LCD technology, and at the end of the evening, or if company comes by, press another button and the TV shuts off and the screen rolls back up into the unit, completely out of the way.
Yes, LCD and plasma technology has ushered in an era of large screen theater-like experiences. But OLED technology will take that Digital Cable TV experience to a whole new level!
