Abstract

The invention discloses a light emitting element which comprises a printed circuit board and a light emitting diode. The printed circuit board comprises a photosensitive solder resist layer. The materials of the photosensitive solder resist layer comprise at least one of conductive nanoparticles and a photoluminescent material and a reflective material. The light emitting diode is arranged on thephotosensitive solder resist layer of the printed circuit board and electrically connected with the printed circuit board. According to the light emitting element provided by the invention, at least one of conductive nanoparticles and the photoluminescent material is added to reduce the problem of light degradation caused by the photosensitive solder resist layer and improve the reflectivity of the photosensitive solder resist layer.

Description

technical field [0001] The present invention relates to a light-emitting element, more specifically, to a light-emitting element that uses at least one of conductive nanoparticles, photoluminescent materials, and reflective materials as the material of the photosensitive solder resist layer. Background technique [0002] Light emitting diodes (LEDs) have advantages such as long life, small size, high shock resistance, low heat generation, and low power consumption, so they have been widely used as indicators or light sources in households and various devices. In recent years, light-emitting diodes have developed towards multi-color and high brightness, so their application fields have been extended to large outdoor billboards, traffic lights and related fields. In the future, light-emitting diodes may even become the main lighting source with both power saving and environmental protection functions. [0003] Generally, a display device with light-emitting diode grains is co...
