Abstract

The invention discloses a light source device which comprises at least one light-emitting diode packaging structure. The light-emitting diode packaging structure comprises a packaging substrate, a first light-emitting diode grain, a second light-emitting diode grain and a packaging layer. The first light-emitting diode grain is used for emitting a first light beam, and the full width at half maximum of a frequency band of the first light beam is 30-40 nm; the second light-emitting diode grain is used for emitting a second light beam, and the full width at half maximum of a frequency band of the second light beam is 30-40 nm; and the packaging layer comprises a wavelength conversion material, the wavelength conversion material is used for generating a third light beam after being excited bythe first light beam and the second light beam, and the full width at half maximum of a frequency band of the third light beam is 10-50 nm. The light source device provided by the invention is high in color contrast, and the use experience of consumers can be improved. The invention further provides a display comprising the light source device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light source device and a display. Background technique [0002] With the development of science and technology, displays have been widely used. A display generally includes a light source, a light guide plate, a diffuser plate, and a filter, among which the quality of the light source will directly affect the display quality of the display. At present, the color contrast of the light source is low, which cannot meet the requirements of consumers. At the same time, it also seriously affects the color contrast of the display, giving consumers a lower user experience. Contents of the invention [0003] In view of this, the present invention provides a light source device with high color contrast. [0004] In addition, there is also a need for a display with the light source device. [0005] The present invention provides a light source device, including at least one light e...
