A ballistic and blast protective composite panel includes a first composite layer and a second composite layer. The voltage ramp circuit utilizes a two-stage current divider circuit to generate a very low, stable current signal, and an integrator circuit including a relatively small, integral capacitor to generate the ramp voltage signal in response to the very low current signal. The device can perform rendering processing in which at least one of the pixels that form a first one of the at least two different types of subsets lends a luminance to a second type of subset. The springs engage with the brackets to exert first and second torques between the first and the second brackets.
