Step 4, play in step 3 the picture made on TV in order;
Electric current corresponding to each subregion tested by step 5, use oscilloscope; Testing standard is: only have the corresponding lamp bar of the first color region to have electric current, and electric current is the maximum of television set initial setting, the second color region current value should be 0.
Further technical scheme also comprises determination step, if the inspection of all subregions all meets testing standard, represents that the subregion of backlight is accurate.
Further technical scheme is that backlight subarea scheme comprises: number of partitions and scanning sequency.
Further technical scheme makes in step 2 that to detect the quantity of picture used equal with described backlight subarea quantity.
Further technical scheme is that in step 3, the first color region is white portion, and described the second color region is black region.
Further to be white portion gray scale be technical scheme: red 255 rank, green 255 rank, blue 255 rank; Black region gray scale is: red 0 rank, green 0 rank, blue 0 rank.
Further technical scheme is the area that the first color region area is less than LED television backlight subarea corresponding to the first color region described.
Further technical scheme is LED television backlight subarea is 2*8 subregion.
Compared with prior art, the invention has the beneficial effects as follows: the present invention can confirm that whether LED television backlight subarea is normal fast.Method checking efficiency is high, and cost is low.
