Title
(EN) LIGHT EMITTING DIODE MODULE
(FR) MODULE DE DIODE ÉLECTROLUMINESCENTE
Abstract
(EN)
A light emitting diode (LED) module includes an integrated substrate, the integrated substrate including a plurality of LEDs; a glass substrate; and a signal wiring layer provided on the glass substrate. The signal wiring layer includes a plurality of signal electrodes configured to supply a data signal to the plurality of LEDs. The LED module further includes a conductive pattern provided on at least one surface of the integrated substrate, and connected to a ground.
(FR)
Un module de diode électroluminescente (DEL) comprend un substrat intégré, le substrat intégré comprenant une pluralité de DEL ; un substrat de verre ; et une couche de câblage de signal disposée sur le substrat de verre. La couche de câblage de signal comprend une pluralité d'électrodes de signal conçues pour fournir un signal de données à la pluralité de DEL. Le module de DEL comprend en outre un motif conducteur disposé sur au moins une surface du substrat intégré, et connecté à une masse.
