BenQ Confidential (yyyy/mm/dd)  2005, BenQ Corporation What is Gray-to-Gray response time? Comparing to on/off response time which indicates only the response time between black and white, gray-to-gray response time represents the response time within all colors.

BenQ Confidential (yyyy/mm/dd)  2005, BenQ Corporation On/off 12 ms v.s. On/off 8ms 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

BenQ Confidential (yyyy/mm/dd)  2005, BenQ Corporation What is Gray to Gray response time? On/off response time: The image performance in a on/off 12ms response time monitor is not good. Ghost and lagging still can be seen easily on 12ms LCD

BenQ Confidential (yyyy/mm/dd)  2005, BenQ Corporation What is Gray to Gray response time? With AMA technology, BenQ improve the gray to gray response time to average 8ms (even lower), the image quality is better than ever. On/Off 25ms On/Off 8ms GTG 8ms

BenQ Confidential (yyyy/mm/dd)  2005, BenQ Corporation What is AMA? Advanced Motion Accelerator By giving higher voltage to liquid crystal, BenQ improve the GTG (Gray to Gray) response time and image became more clear and vivid.

BenQ Confidential (yyyy/mm/dd)  2005, BenQ Corporation What is AMA? Backlight Liquid Crystal User can see the image after liquid crystal change it’s direction Given greater voltage, liquid crystal could turn faster and user could see the image earlier  no ghosting and lagging shown in screen User Before the liquid crystal turned, user can not see the image After the liquid crystal turned, user can see the image

BenQ Confidential (yyyy/mm/dd)  2005, BenQ Corporation What is Gray level?  There are 256 gray levels in a 8 bit panel. 2 8 =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).

BenQ Confidential (yyyy/mm/dd)  2005, BenQ Corporation What is Gray-to-Gray response time? Example: TN 12ms panel response time chart ms Start Level Target Level 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 time  RS 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.

BenQ Confidential (yyyy/mm/dd)  2005, BenQ Corporation The difference between CRT and LCD CRT LCD  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. No Blur Blur
