example 1
[0088] image 3 The spectrum of the light source device of Example 1 and the color filter characteristics of the LCD panel are shown. The meaning of the horizontal and vertical axes is the same as Figure 8 in the same.
[0089] In this example, a combination of a CCFL tube 3 and an LED 4 to which B phosphorescence and G phosphorescence were applied was used as a light source device, and mercury was used as an excitation gas. The B phosphorescence quality and G phosphorescence quality of CCFL tube 3 are the same as those in Comparative Example 2, and LED 4 is an AlInGaP base red light-emitting diode (reference figure 2 ). exist image 3 , W3 indicates the emission spectrum of the combination of CCFL tube and LED. The meanings of CFB, CFG, and CFR are the same as those in Comparative Example 1 (refer to Figure 8 ).
[0090] In the emission spectrum W3, the peak PB at 450 nm is the peak of the B phosphorescence of the CCFL tube 3 . Around 510 to 520nm (at image 3 The...
example 2
[0094] Figure 4 The spectrum of the light source device of Example 2 and the color filter characteristics of the LCD panel are shown. The meaning of the horizontal and vertical axes is the same as Figure 8 in the same.
[0095] In this example, a combination of a CCFL tube 3 and an LED 4 to which B phosphorescence and G phosphorescence are applied is used as a light source device, and an inert gas xenon (Xe) is used as an excitation gas (refer to figure 2 ). Other structures are the same as in Example 1. exist Figure 4 , W4 indicates the emission spectrum of the combination of CCFL tube and LED. The meanings of CFB, CFG, and CFR are the same as those in Comparative Example 1 (refer to Figure 8 ).
[0096] In this example, since xenon, an inert gas, is used as the excitation gas instead of mercury, the emission line spectrum around 404nm, 436nm, 546nm, and 578nm unique to mercury disappears. The color gamut of the case where the light source is used as a backlight ...
example 3
[0098] Figure 5 The spectrum of the light source device of Example 3 and the color filter characteristics of the LCD panel are shown. The meaning of the horizontal and vertical axes is the same as Figure 8 in the same.
[0099] In this example, as in the case of Example 2, a combination of a CCFL tube 3 and an LED 4 to which B phosphorescence and G phosphorescence were applied was used as a light source device, and xenon, an inert gas, was used as an excitation gas (refer to figure 2 ). However, unlike Example 2, the G phosphor Zn used in PDP (Plasma Display Panel) is used 2 SiO 4 : Mn (P1G of Kasei Optonix, Ltd.) as the G phosphorescent substance. Such as Figure 7 As shown, the emission spectrum from the G phosphor has a single spectrum with a peak wavelength of 520 to 530 nm and a half width of 45 nm or less. Other structures are the same as in Example 2. In addition, in Figure 5 In , W5 indicates the emission spectrum of the combination of CCFL tube 3 and LED ...
