Controller simplifies switch from CRT to LCD

The new GC2000 is a controller interface for enhancing the on-screen performance of LCD displays.

The new GC2000 is a controller interface for enhancing the on-screen performance of LCD displays.

The new GC2000 has been developed by GDS to allow a CRT monitor to be replaced with an LCD panel, without the original functionality of the display being affected.

The controller also extends the capabilities of the LCD panel, by enabling additional input signals such as DVI standard and Pal to be rescaled and played into the panel.

This new controller converts analogue input signals such as VGA, Hercules, CGA and EGA as well as digital signals such as DVI, TMDS and PanelLink.

With the controller, the fixed resolution of the LCD panel does not restrict the type of input signal.

Even if a low resolution is sent to the LCD panel, the GC2000 ensures that the output image is clean, clear and fills the entire screen, every time.

All controller boards come fitted with a graphics chip that features a finite impulse response (FIR) filter which has the capability of upscaling or downscaling the signal to fit the LCD screen.

The result - no more stretched characters, no more missing pixels, just a clear, stable display.

The design of the controller board means that the graphics chip can be replaced by new chips as and when they are developed.

The controller interface supports LCD panels from 6.4 to 20.1in and displays up to 16.8 million colours.

Horizontal and vertical frequency ranges are 15-110Khz and 40-120Hz, respectively.

The board runs from a single 12V DC (+/-300mV) power supply over a 0-55C operating temperature range.

The GC2000 controller also comes with an optional energy saving capability (VESA DPMS) and can be supplied without the software if preferred.
