Abstract

The invention provides a light-emitting element, including a first light-emitting chip for emitting light of a first color, a second light-emitting chip for emitting light of a second color, a third light-emitting chip for emitting light of a third color, and an encapsulant. The first light emitting chip, the second light emitting chip and the third light emitting chip are arranged in sequence along the arrangement direction. The packaging colloid covers the first light-emitting chip, the second light-emitting chip and the third light-emitting chip and has a light-emitting surface, wherein the packaging colloid has an arc-shaped body and a connecting portion. A curved body has a uniaxial curvature change.

Description

technical field [0001] The present invention relates to an optical element and an optical device, and in particular to a light emitting element and a display device. Background technique [0002] Light-emitting diode chips have the advantages of long life, small size, and low power consumption, so they have been widely used in various light-emitting elements. In recent years, light-emitting elements have developed towards multi-color and high-brightness, so the application fields of light-emitting elements have been extended to display devices, such as: large outdoor billboards, traffic lights, etc. [0003] Known light-emitting elements include red light-emitting diode chips, green light-emitting diode chips, blue light-emitting diode chips, and encapsulants. The red light emitting diode chip and the blue light emitting diode chip are respectively arranged on two opposite sides of the green light emitting diode chip. The packaging colloid covers the red light emitting dio...
