A joystick control device is disclosed for use in a cab of a spreader for the snow and ice control industry. The reactor includes utilizes a plurality of beds of methanol synthesis catalyst in series to form methanol product from synthesis gas. The EL material is between at least two of the conductor layers, and at least one of the conductor layers is applied adjacent the EL material in a pattern to form a conductive image. Accordingly, the alpha correction can be performed by a GPU, which is not configured to perform gamma correction, thereby increasing the speed at which text rendering can occur. The color filter glass layer may serve as the outermost glass layer in the display module. Finally, the data subjected to the logical XOR function and the majority determination are driven separately to external elements requesting the present data.
