Abstract
A driving system for driving light-emitting modules includes driving current generation modules connected respectively to the light-emitting modules, and a brightness modulation module connected to the current generation modules and the light-emitting modules. Each driving current generation module is configured to receive signals from the brightness modulation module to control a driving current that flows through the light-emitting module it is connected to. The brightness modulation module is configured to generate the signals based on voltages provided at terminals of the light-emitting modules that are connected to the driving current generation modules.
