Abstract: A low blue light backlight module configured to emit a white light is provided. The low blue light backlight module includes a first light-emitting element, a second light-emitting element, a third light-emitting element and a fourth light-emitting element. The first light-emitting element is configured to emit a first light having a peak emission wavelength of about 610-660 nm. The second light-emitting element is configured to emit a second light having a peak emission wavelength of about 520-550 nm. The third light-emitting element is configured to emit a third light having a peak emission wavelength of about 480-580 nm. The fourth light-emitting element is configured to emit a fourth light having a peak emission wavelength of about 445-470 nm. The white light has an emission spectrum, and an area ratio of the spectrum under wavelength of 415-455 nm to the spectrum under wavelength of 400-500 nm is below 50%.

Abstract: A platinum complex represented by general formula (I) or general formula (II) and an organic light-emitting diode using the same are provided. In general formulae (I) and (II), L1 and L2 are nitrogen-containing heterocyclic bidentate ligands; R1 is a substituted or unsubstituted C1-C12 alkyl group, or a substituted or unsubstituted C6-C12 aryl group; R2 is hydrogen, halogen, a substituted or unsubstituted C1-C12 alkyl group, or a substituted or unsubstituted C6-C12 aryl group; R3 is hydrogen, a substituted or unsubstituted C1-C12 alkyl group, or a substituted or unsubstituted C6-C12 aryl group; RF is —CmF2m+1, m is an integer of 1 to 3; X1 to X6 are independently carbon or nitrogen; provided that when X6 is nitrogen and X3, X4, and X5 are carbon, R3 is not hydrogen.
