LCD Introduction
• LCD (Liquid Crystal Display) A type of display used in digital watches and many portable
computers. LCD displays utilize two sheets of polarizing material with a
liquid crystal solution between them. An electric current passed through the
liquid causes the crystals to align so that light cannot pass through
them. Each crystal, therefore, is like a shutter, either allowing light to pass
through or blocking the light.

LCD Panel Type
• Mono (Monochrome): actually using two colors, one for the display image (the foreground) and one for the background.
• STN (Super Twisted Nematic): using the Voltage to change the liquid crystal twisted angle to see the display; maximum 90 point of view.
• DSTN (Double Super Twisted Nematic): a passive-matrix LCD technology that uses two display layers to counteract the color shifting that occurs with conventional super twist displays.
• TFT (Thin Film Transistor): in which each pixel is controlled by from one to four transistors. The TFT technology provides the best resolution of all the flat-panel techniques, but it is also the most expensive. TFT screens are sometimes called active-matrix LCDs.

1. How to know the maximum support of
resolution and color?
Memory size> (resolution x BIT pixel) / 8 For example: 2MBytes > (1024x768x16) /8 = 1.57MBytes 2MBytes > (1280x1024x8) /8 = 1.31MBytes
p.s. : 8 BIT pixel = 2x2x2x2x2x2x2x2 = 256 color

2. Why the display does not show full screen in DOS mode when the BIOS LCD type set over than 640x480 in GX1 board?
The default display resolution is 640x480 in DOS mode and GX1 does not support full screen function. If your LCD specification is higher than 640x480, the display will show narrower than your LCD screen.
