The GD-100 models were
introduced in September 2010. These basic models were the digital answer
on the GA-100 and GA-110 models. Although the GD-100 models must be
considered the basic models, Casio also promotes this mode as X-Large
models. This specific model, the GD-100-1B is even promoted by clothing
brand XLarge in a poster where their mascot, a big gorilla, recommends
this specific model.
On the left a GA-110 model
(of the Hyper Colors series). You can see that the GD-100 uses the same
case, bezel and straps of the GA-100 and GA-110 models.
The GD-100 has a new sort of
backlight introduced. The backlight is not provided by an
electroluminescent back panel, but by two LEDs that provide enough light
to light up the complete display.
