Abstract
An LED display screen configuration system for improving the gray scale recognition effect of human eyes used in a direct-view LED display screen sets a first current matched with a selected gamma value to output light to define a first brightness range, then uses a brightness X˜100% in the first brightness range to form a first modulation interval and a brightness Y % as a minimum allowable value, and sets the next current to form the next modulation interval, and so on and so forth. In any two adjacent modulation intervals, the maximum brightness outputted from the latter modulation interval is equal to or slightly greater than the brightness X % of the previous modulation interval, so that the respective current outputs of the 1to the Nmodulation intervals show a power decreasing relationship, so as to set or switch to the most suitable modulation interval for the practical brightness requirements.
