る。As shown in FIG. 5, the relationship between the input signal of the conventional panel 9 and the light emission luminance of the discharge cell of each color is proportional to the input signal and the light emission luminance is the maximum value of Sm. In this case, a maximum luminance of 256 gradations is obtained. FIG. 6 is a chromaticity diagram of the XYZ color system.
(Xb, Yb), G (Xg, Yg), R (Xr, Yr)
Are blue, green, and red phosphors 8 in the conventional panel 9.
The chromaticity coordinates of the light emission of groups b, 8g, and 8r are shown. FIG.
Indicates that by controlling the light emission luminances of the blue, green, and red discharge cells 7b, 7g, and 7r, respectively, light emission in a range surrounded by the triangle BGR can be obtained. Also, when the blue, green, and red input signals are the maximum input signal Sm, the emission luminance of the discharge cells 7b, 7g, 7r group becomes the maximum luminance of 256 gradations, and the maximum white light emission luminance of 256 gradations is obtained. The chromaticity coordinates of this white display emission are W 1
Indicates that In this case, when the coordinates W 1 of the chromaticity of the white display light emission or offset from white, the color temperature is not the chromaticity such as low desire adjusts blue, green, the level of the red input signal panel Can be set to appropriate coordinates. For example, as shown in FIG. 6, the move the chromaticity of the white display light emission from the coordinates W 1 to the coordinate W 2 in the direction of the blue chromaticity, and the level of the blue input signal as it is, This is made possible by reducing the levels of the green and red input signals to appropriate values.

までの発光輝度しか得られなくなってしまう。However, when the relation between the input signal of the conventional panel 9 and the light emission luminance of the discharge cell shown in FIG.
Since the luminance of the panel is determined by a combination of a plurality of subfields having a luminance weight based on the binary method during the field period, the light emission luminance of the panel is not a continuous and infinite relation to the input signal. FIG. 7 shows the case where the gradation control of the light emission luminance of the display is performed by the combination of the luminances of the eight subfields having the luminance weight based on the binary method during the period of one field as described above. Thus, the relationship is discontinuous and finite in 256 steps. Therefore, as described above, the chromaticity of the white display light emission shown in FIG.
To move from one coordinate to the coordinate W 2 in the direction of the blue chromaticity case where the level of the blue input signal as it is, reduced green, the level of the red input signal, FIG. 8 (A ), (B) and (C), the level of the blue input signal is set to the maximum value Sm, and the levels of the green and red input signals are set to, for example, 0.8 × Sm and 0.6 × Sm, respectively.
m. However, in this case,
The blue discharge cells 4b group can display and emit light up to the maximum luminance of 256 gradations, but the display light emissions of the green discharge cells 4g and the red discharge cells 4r move in the direction of the broken arrows in FIG. Therefore, 256 × 0.8 = 205 respectively
Only the emission luminance up to the gradation and the emission luminance up to 256 × 0.6 = 154 gradation can be obtained.

品質が著しく損なわれるという問題があった。As described above, in the conventional panel 9, light emission luminance of up to 256 gradations can be obtained in white display. However, in the case of displaying other than white display, for example, a single color of green or red, 205 light emission is required. Emission luminance of gradation, 154
There is a problem that a display exceeding the emission luminance of the gradation cannot be performed, and the gradation display quality is significantly impaired.
