Abstract: A pixel unit includes a red LED chip, a green LED chip, and a blue LED chip. Each of these chips has an optical density concentration zone and a reference line passing through the geometric center of the top-view shape of the chip. The optical density concentration zone of each of these chips is deviated to one side of the respective reference line of the chip. The reference lines of the chips are parallel to each other. The optical density concentration zones of the chips are all deviated to the same side of the respective reference line.

Abstract: An emission spectrum of a manganese-doped red fluoride phosphor includes a zero phonon line crest and a crest. The zero phonon line crest has a first peak emission wavelength and a first intensity (I1). The crest has a second peak emission wavelength and a maximum intensity (Imax) except for the zero phonon line crest. The second peak emission wavelength is greater than the first peak emission wavelength. A ratio (I1/Imax) of the first intensity (I1) to the maximum intensity (Imax) is ranged from about 0.2 to about 8 such that a luminous decay time of the manganese-doped red fluoride phosphor is less than 10 ms.
