Abstract

An LED display apparatus includes an LED display module, an inner frame member, and a supporting unit. The LED display module has an array of light emitting diodes mounted thereon, and a longitudinal axis. The inner frame member is disposed to confine the LED display module therein, and has a size sufficient to permit movement of the LED display module in opposite directions of the longitudinal axis. The supporting unit mounts the LED display module in the inner frame member such that the LED display module is movable back and forth in the inner frame member along the longitudinal axis.
