This abstract first appeared for US patent application 20250109985 titled 'COMPENSATION FOR CROSSTALK BETWEEN ELECTRONIC DISPLAY AND AMBIENT LIGHT SENSOR
Original Abstract Submitted
an electronic display includes an ambient light sensor (als) located beneath an active area to sense ambient light above the active area. the als is synchronized with blanking periods of a display pixel on the active area. an emission-off scale factor is calculated based on an emission profile of the display pixel when the display pixel is turned off. the emission-off scale factor is used with display content to calculate a crosstalk compensation for the als.
