Abstract: Technologies are described herein for photobleaching a display. A display may be photobleached by exposing the display to light emitted by an external lamp and/or may be photobleached using one or more display lights of the electronic device during a burn-in period. In some examples, the light emitted by the lamp is filtered to remove wavelengths below a certain wavelength. The light that is received by the display from the lamp may include wavelengths between about 310 nm and 700 nm. These wavelengths correspond to visible light and near-visible light. The display may be exposed to the light for some duration or until some dose of light is received by the display. In other configurations, a burn-in period is performed for about eighteen hours.
