Data Sheet

8.0 Dark Uniformity, Ud

Figure 3 exemplifies the definitions of the terminology, which are used to explain the video signal characteristics. Dark uniformity is

defined as Ud = Vdmax - Vdmin; where Vdmax and Vdmin are the maximum and minimum voltage of Vd, the average dark level of total

pixels in the scan line when the LED light is turned off. Vd is measured from the reset level and the amplitude between the dark level

and this reset level is called pedestal. The pedestal level is caused by the resetting operation of the pixel. Although the pedestal

remains constant for a constant clock frequency, the reset level will vary from ground because the dark level, Vd, is factory adjusted to

ground (0V).
