Abstract: An LED arc display includes at least one LED matrix array module. Each LED matrix array module is composed of a plurality of LED matrix units arranged regularly. Each LED matrix unit includes a display surface, and the display surface has an outer contour. The outer contour is a non-quadrilateral. Therefore, a non-smooth visual experience caused by assembly tolerances of the plurality of LED matrix units can be improved by using non-quadrilateral outer contours of each LED matrix unit.

Abstract: The present invention relates to a light-emitting module and a light-emitting display panel. The light-emitting module comprises a substrate, one ore more light-emitting unit, and a driving unit. The substrate comprises a power input, a ground, a data input, a data output, a clock input, and a clock output. The one or more light-emitting unit is disposed on the substrate. The driving unit is connected electrically to the data input, the clock input, and the power input, respectively, and controls the color-scale changes of the light-emitting unit. A plurality of light-emitting modules are disposed on the circuit board. The control signal controlling the plurality of light-emitting modules is transmitted in series. It isn't required to connect the plurality of light-emitting module to additional connecting wires for signal control. Accordingly, shading of the light passing through the display panel and inferior transmittance due to excess electrical connecting wires may be prevented.
