The refresh rate of LED dance floor

The refresh rate of LED dance floor (http://www.visslighting.com/en-us/product/23.html) on a different feel of the display may be different. CRT is the use of spot scanning light while the PDP is a surface discharge light. Camera sampling frequency is 50Hz, whether large screen refresh rate is 50Hz or 100Hz, will not produce noticeable interference frequency difference.

This case may also have some time, for frequency-division / line minutes / hours total due to improved the refresh rate of LED dance floor, you must take other appropriate measures to compensate for the total amount of information, or is likely to occupy space data transmission and other ills caused by poor tone.

One of the characteristics of human vision is limited to observe the movement of the resolution, independent screen in a series of discrete visual residual effect looks like a continuous as possible.

This statement is inaccurate, the odd and even field television camera side, although the vertical axis sampling is interleaved (interlaced sampling), but (the sampling frequency on the time axis in the timeline which is equivalent to the sequential samples twice the number of frames), which is a hit with the movie playing twice in the situation on the different properties of LED dance floor display.
