Abstract
Official abstract text for this publication.
Systems, methods, and devices are provided in which photodetectors disposed throughout a display are used to control the display brightness. The photodetectors are to be used for ambient light sensing, proximity sensing, or to compensate for aging OLEDs. In some embodiments, photodiodes are fabricated with OLEDs during the TFT fabrication process. In some embodiments, the photodetectors may be disposed throughout the display in zones containing OLEDs. The photodetectors are used to control the display brightness and color for the OLEDs in areas around each photodetector based on ambient light, aging, and/or nearby objects. A controller makes driving strength adjustments to the OLEDs in each zone independent of other zones. Photodetectors disposed throughout the display may improve proximity sensing and provide additional functionality to the device.
First claim
Opening claim text (preview).
What is claimed is: 1. An electronic device, comprising: a housing; a processor disposed within the housing; one or more input structures configured to transmit input signals to the processor; and a display, comprising a display screen and a controller, the display screen being coupled to the housing, the display screen comprising: a plurality of organic light emitting diodes (OLEDs) disposed across the display screen, wherein each OLED of the plurality of OLEDs emits ligh…
