The bidder selected constant current source LED display driver IC, the display light-emitting element LED (light emitting diode) for direct drive to ensure that every light-emitting diode display consistency. The display shows the effect of the screen image brightness uniformity, the transition smooth, delicate texture, real and moving. If the circuit is not a constant current source drive technology, as each light-emitting diode display is inconsistent, and some partial light, some dim image on the screen there will be a few scattered highlights and dark points, image display rough, abrupt transition.
