Abstract(in English) We describe as follows, the newest techniques used to produce a high quality picture of a large display, full-color LED screen planned and made for an event-hall. (1)Improving the color uniformity of the picture by individually correcting the variation of brightness on the display element. (2)Improving the definition by sampling a picture at the position of the display element. (3)Creating a Super-wide viewing angle in all directions by arranging the chip LED elements on a plane. (4)Decreasing the dark luminance with a black package of LED elements. (5)Improving the contrast ratio with high bright LED elements. (6)Stopping the flicker caused by the absence of luminous lag of an LED element by encreasing the luminous frequency several times. (7)Improving the definition by arranging luminous elements more densely.
