Abstract: An LED display apparatus comprises two or more LED arrays for performing as a light source, a housing to house the LED arrays, transparent panels attached to the housing so that the LEDs can shed light through the side of the transparent panels, and dispersion scratches on the transparent panels for refracting, reflecting and diffusing LED light wherein the dispersion scratch is configured to form a sign, and a plurality of panels treated with fluorescent paint attached to each transparent panel for enhancing the intensity of LED light refracted or reflected. The dispersion scratch is configured to be a letter, sign, symbol or design component for being bright as against the rest of dark plain background of the transparent panel. Therefore, the part of the transparent panels having dispersion scratches becomes brighter as against the rest of dark plain background of the transparent panels.
