8. ultrahigh resolution as claimed in claim 1 shows UHDTV composite test methods, it is characterized in that, it is superimposed dynamic random
Moving cell is movement position, speed, the colored bead of direction completely random, and its movement properties can not be predicted, therefore can be most
Measure to limits the motion process ability of display device to be measured；
Moving cell designs the filled circles that 2 radiuses are 40 pixels, and only occurs outside great circle；
Outside initial position left and right two parts respectively in static composite test pattern of 2 motion beads, great circle, randomly generate；It is left
The initial position of right two beads is independent mutually, orthogonal；
After bead setting in motion, the direction of motion of each bead is randomly choosed by program in the range of 0 ° -360 ° respectively, left and right
The direction of motion of two beads is independent mutually, orthogonal；
Bead is moved according to straight line path, with the movement velocity of user input；Bead move during, run into test chart edge,
And the big rounded edge in center, it will change path according to mirror-reflection rule；
According to the initial position and the direction of motion randomly generated, bead of the initial position in left side have into right side move can
Can, bead of the initial position on right side also has the possibility moved into left side.
