The electrodes of a light emitting diode (LED) is coupled to the terminals of a package with solderless pressure contacts. Each package is housed in a module with a bed on which the bottom electrode of the LED rests, and a pressure plate which is coupled to the top electrode of the LED. The pressure plate slides along four vertical posts to exert pressure to an LED package against a bed to form solderless pressure contacts. A plurality of LED packages can be lined up in a row to form a light strip, with the top pressure plate extended to form the bed of an adjacent module. A plurality of LED packages can also be arranged a matrix array display panel, where a plurality of lower terminals rests on one row of common bed of a number of parallel horizontal common beds, and where a plurality of upper terminals are pressed under a column of parallel vertical common pressure plates, so that any individual LED at the cross-point of a common bed and a common pressure can be randomly accessed.
