Abstract

The invention discloses a light source module and an electronic device. The light source module includes a light guide plate, at least one light-emitting element and a quantum dot element. The light guide plate has a light entrance surface and a light exit surface. At least one light-emitting element is disposed on the light incident surface to provide first color light, and includes yttrium aluminum garnet. The quantum dot element is arranged on the light exit surface of the light guide plate to convert part of the first color light into the first monochromatic light. The first color light and the first monochromatic light are mixed to form white light.

Description

technical field [0001] The present invention relates to a light source module and an electronic device, and in particular to a light source module and an electronic device with a quantum dot (QuantumDot) element. Background technique [0002] Generally speaking, the light-emitting element of the wide-color-gamut display device can use a blue light-emitting diode chip, and use it with a quantum dot (quantum dot) element. Quantum dots are materials with good light-absorbing and luminescent properties. They have narrow Full Width of Half-maximum, high luminous efficiency, and a fairly wide absorption spectrum, as well as high color purity and saturation. Therefore, quantum dot elements have been gradually applied in display panel technology in recent years, so that the image frame of the display device has a wide color gamut and high color saturation. However, bluish areas often appear in the edge area of ​​the display panel, thereby affecting the quality of the display image....
