Abstract
An exemplary LED module includes a base, an anisotropic conductive film on the base, multiple LED dies on the anisotropic conductive film, multiple first electrodes between the base and the anisotropic conductive film, and multiple second electrodes on the LED dies. The LED dies are arranged in multiple rows by multiple columns. The first electrodes each are elongated and parallel to each other. The second electrodes each are elongated and parallel to each other. The LED dies of each column are connected to one of the first electrodes electrically. Each second electrode is electrically coupled to the LED dies of one row.
