The rate of runaway of the LED display
The pixel runaway rate refers to the proportion of the display's Minimum imaging unit (pixel) operating abnormally (out of control). And the pixel out of control there are two modes: one is blind spot, that is, when the need to light it does not light, called blind Point; two is often bright spot, in need not bright when it has been on the light, called the constant bright spot.
For the sake of simplicity, we are according to the LED display of each base color (that is, red, green, blue), respectively, the statistics and calculation of runaway pixels, take the maximum value as the screen's pixel runaway rate.
The domestic LED display in the factory will be aging (baking machine), the loss of control of the LED lights will be repaired and replaced, "whole screen pixel runaway rate" control within 1/104, "area pixel runaway rate" control within 3/104 is no problem, Even some individual manufacturers of enterprise standards require the factory does not allow out of control pixels, but this will increase the manufacturer's manufacturing and maintenance costs and prolong the shipping time.
