| What is CyberDisplay? | LV Architecture | MVA Technology |
The small size of the CyberDisplay LCD means lower power consumption both from the display and backlight. In addition, Kopin's patent pending low-voltage (LV) architecture further reduces the power consumption.
The input video voltage levels of Kopin's LV-series displays are half the typical values for other LCDs. Instead of the usual DC-coupling of the input, Kopin's LV architecture uses input coupling through capacitors to effectively double the voltage written to pixels. It also features the integrated switch circuitry to restore the DC level, which is required for proper LC operation. The reduced interface voltage swing is compatible with CMOS driver ICs, resulting in lower power consumption and lower cost.
In the LV architecture, a single amplifier drives the VID signal having a swing of 1 x Vsw. The Swing of the VIDH and
VIDL signals is still limited to 1 x Vsw, but the combined voltage range presented to the display is 2 x Vsw.
