OLED darkens by controlling the flow of electric current through organic materials that emit light when stimulated. When a pixel needs to darken, the electric current is reduced or turned off completely, causing the organic materials to emit less or no light. This allows OLED displays to achieve true black levels and high contrast ratios, as each individual pixel can be controlled independently to produce varying levels of darkness. This ability to selectively darken pixels also contributes to OLED's energy efficiency and superior picture quality. **
