(see figure 4) luminance contrast ratio (cr) is defined mathematically note (2) definition of response time (tr, tf):
ATM0700L26(az displays) tft midule v1.0 az displays 11 note (3) definition of viewing angle: viewing angle is the angle at which the contrast ratio is greater than 10. the viewing angles are determined for the horizontal or 3, 9 o ? clock direction and the vertical or 6, 12 o ? clock direction with respect to the optical axis which is normal to the lcd surface. note (4) definition of optical measurement system. the optical characteristics should be measu red in dark room. the optical properties are measured at the center point of the lcd screen,(response time is measured by photo detector topcon bm-7, other items are measured by bm-5a/field of view :1 /height 500mm.)
