摘要： Provided are a light source module and a backlight display module. The light source module includes a flexible printed circuit board and a plurality of side-emitting LEDs. The flexible printed circuit board extends along a central axis. The plurality of side-emitting LEDs are sequentially arranged along the central axis and bonded to the flexible printed circuit board, and a light-emitting surface of one side-emitting LED of the plurality of side-emitting LEDs is perpendicular to a bonding surface of the flexible printed circuit board.

摘要： The disclosure provides an LED white light device, including a blue light chip and phosphors. The blue light chip has a band of (455-470) nm. The phosphors include a dual-band yellow phosphor and a red phosphor having an excited light peak wavelength range of (610-660) nm. The yellow phosphor and the red phosphor are mixed according to a proportion of 1:(0.03-0.2) and cover the blue light chip, such that blue light emitted by the packaged LED white light device has a peak wavelength range of (450-465) nm. The disclosure also provides a preparation method of an LED white light device and an LED backlight module adopting the above LED white light device. The disclosure achieves the effects of blue light prevention, high color gamut and pure white simultaneously, Color uniformity and consistency are good, and a blue-green-red three-color continuous spectrum is provided, which is closer to a solar spectrum.
