Display Device And Display Module

Abstract

A display device and a display module. The display module includes: a blue LED chip, a yellow phosphor layer and a colour filter. A peak wavelength of a blue light emitted from the blue LED chip is in a range of 460±5 nm. The blue LED chip excites the yellow phosphor layer to emit a white light. The colour filter is disposed outside the yellow phosphor layer, and the white light emitted irradiates on colour filter. Through right shifting the peak wavelength of the blue band emitted from the blue LED chip to about 460 nm to realize the low blue energy and decrease the radiation. The transmittance of blue light of the colour filter is less than 7%, the transmission peak wavelength of blue light is in a range of 440-450 nm. The display module can decrease the energy of the blue band and ensure the display effect.
