This module is based on the Chi-Mei Innolux (CMI) model G121X1-L01 color LCD integrated with the GemLight(R) high brightness LED backlight. The GL-CMX121B has the same dimensions and mounting as the original CMI module. This module has a full industrial environmental operating range of -30C to +70C (see product specification).
With the GemLight BC12V430-01B backlight controller this module produces a screen brightness of over 1700 nits. If higher screen brightness is required and proper heat dissipation is provided, this module may be operated as high as 2200 nits using the GemLight backlight controller model BC12V600-01B.
