System for adaptive non-linear light dimming of electro-optical devices comprises main transistor, resistance element coupled to drain of main transistor, light-emitting bank including at least one light-emitting device, and luminance adjustment circuitry coupled to source of main transistor. Luminance adjustment circuitry causes input voltage to the system to have a non-linear relationship with current through light-emitting bank. Luminance adjustment circuitry includes slope-point components coupled in parallel. When a first predetermined voltage level is supplied to the system, the first slope-point component allows a first predetermined amount of current to flow to the light-emitting bank, and when a second predetermined voltage level is supplied to the system, the first slope component allows the first predetermined amount of current to flow to the light-emitting bank and the second slope-point component allows a second predetermined amount of current flow to the light-emitting bank. |
