Making LCD Displays Snappier

newSlashUser points out a very interesting article at ExtremeTech about a new means of more quickly controlling LCD panel response, so the old complaint that LCD panels make poor displays for gaming and high-motion video may be whittled down a bit. As a bonus, the change is all in the controller, so it doesn't require any change in the way the panels are manufactured.

LCDs lifespan limited by OLEDs anyway

[bryan1945]

Organic LEDs are on the way in probably about 5 years or so, and I am willing to wait for them. Cheaper to produce, no backlight, and flexible. Production screens for cell phones and camcorders are being produced, so it's only an engineering step to up-size them. They are also more durable and scaleable than LCDs.

It's nice that LCDs are getting better, but even better stuff is just down the pike.

Two polarizing filters encase the liquid crystals in the LCD. One filter is etched with horizontal lines; the other with vertical. Light enters the liquid-crystal compartment parallel to the first filter's lines and follows the path of the liquid crystals. If the liquid crystals become energized, the crystals and light rays do not twist to become parallel with the second filter. Light rays reach the second filter perpendicular to its lines and cannot pass through to the viewer's screen image. If the crystals are not energized, they twist themselves and the light rays to allow light to pass through and illuminate the LCD.

teh way lcd screens work is (through magic) they seperate the white backlight into vertical bands of red, green, and blue (not necessarily in that order).... so you have three sub pixels per pixel, each one is individually controlled.

(that is what microsoft's cleartype(tm) leverages... since, the order of the subpixels are known, you can render to individual subpixels by using color values... and stuff)

(grc.com has a better explination of cleartype)

What do you mean, fixed resolution? Are you saying that you cannot change resolutions at all on LCD screens (which I seem to be able to)?

You can change resolution, but it looks like crap since the image has to be scaled (and pixels interpolated) to fill in. The worst displays used to be 800x600 panels run at 640x480; the available controllers usually just doubled some rows/columns to produce a chunky, uneven image. Newer displays interpolate the pixels so it doesn't look as nasty, but the image still has a blurred appearance at anything other than its intended resolution (typically 1024x768).
