An Analog LCD?

June 1996 / Reviews / Big Picture, Little Box / An Analog LCD?

To work with PC graphics cards, the NEC LCD300 takes a standard analog signal (0 to 0.7 V). The continuous nature of this signal means the LCD300 can read an infinite number of colors. While it's unusual for an LCD panel to use an analog signal, the technologically hard part is designing a panel responsive enough to handle CRT refresh rates. The LCD300 must refresh all it s pixels (1280 by 1024) 60 to 72 times per second; this means the LSI drivers that control the panel must handle a signal frequency of between 96 and 126 MHz, unusually high for an LCD.
