Always room for improvement!!BenQ acted as leader in AMA Technology introduced on 17”

and 19” LCD monitor to improved GTG (Gray to Gray) response time to be 5ms~8ms GTG.

Image ghosting and lagging becomes history!!

BenQ led in 16ms market, (FP767)forced everyone in the playground follows new standard in 2003.

BenQ ahead in 12ms market, (FP71G, FP71E)Visual effect of LCD MNT close to CRT level in 2004.

BenQ speed up in 8ms market, (FP71G+,71E+)Astonishing performance attract gamers

What is Gray to Gray response time?

On/off response time: The response time currently claimed in the market is on/off response time which only improves the image in black and white.Below example shows the improvement between on/off 12ms panel and 8ms panel

What is Gray level?

0 32 64 96 128 160 192 224 255

There are 256 gray levels in a 8 bit panel. 28=256 There are gray levels in all colors.

Gray Level

Examples:

BenQ Confidential (yyyy/mm/dd) 2005, BenQ Corporation

We mark the response time of 0 to 16, 0 to 32, …, 0 to 255 and so on in the following page.

What is Gray-to-Gray response time?

We measure the response time between each level. From 0 level to 16, from 0 level to 32 and so on. The number could be filled in the table below. The traditional on/off response time shows only the 0 to 255 level. For example, when vendor claims that the panel is on/off 12ms, he measures only the 0 level to 255 level, 8ms (tr), and 255 level to 0 level, 4ms (tf).

How to read the chart?The Y-axis shows the response time.The other two axis show the gray level.The color bar shows the response time from one gray level to another.What the chart tells us?The on/off response time is 12ms (10+2). That is the 0 to 255 level response time plus 255 to 0 level response timeRS of the rest of the gray levels are much larger than on/off.

We make a chart of gray-to-gray response time. The chart

would be like the example showing below. The response time is

high in gray levels.

The difference between CRT and LCD

CRTCRT

LCDLCD

For CRT, the electric beam turns on and off is just like lamp light to turn on and off without time lag. The image is clear.

For LCD, it takes a little time to turn cell from current angle to another angle in order to show different gray level. The image is therefore, not clear enough.
