    摘要: The present disclosure relates to the technical field of optics, and discloses a light-emitting module, including: a light-emitting unit layer, including a plurality of light-emitting units, where a light-emitting unit light isolation structure is arranged between two adjacent light-emitting units in part or all of the plurality of light-emitting units. According to the light-emitting module, light emitted by the light-emitting units is prevented from being transmitted in an undesired direction as far as possible by arranging the light-emitting unit light isolation structure between two adjacent light-emitting units in part or all of the plurality of light-emitting units, thereby benefiting improvement of display effect. The present disclosure further discloses a display module, a display screen and a display.

    摘要: A light emitting device is disclosed and includes an emission source configured to emit a primary blue light and a wavelength-converting element configured to convert the primary blue light to a secondary light, where the wavelength-converting element including a red phosphor material having a peak emission wavelength that is less than 620 nm and a green phosphor material having a peak emission wavelength that is greater than 530 nm. The device may have a correlated color temperature (CCT) in the range of 1600K-2500K, may exhibit a melanopic/photopic ratio less than 0.25 and/or may exhibit a radiometric power fraction of light having a wavelength below 530 nm below 0.1.
