LIGHT EMITTING DIODE DISPLAY WITH AGEING COMPENSATION

摘要

The description relates to improving image quality of light emitting diode (LED) displays. Image degradation due to operational ageing, screen burn-in and different ageing speeds of different colours are addressed. One example includes a display, a processor, storage (224), and a pixel run time counter (228). The display can include a set of multiple pixels. Individual pixels can include multiple colour light emitting diodes (LEDs). The processor can be configured to convert image related data (402) into frame renderings for driving the multiple pixels of the display and the storage (224) can be accessible by the processor. The pixel run time counter (228) can be configured to store pixel information for a subset of individual pixels relative to individual frame renderings on the storage. The pixel run time counter may select pixel information to be stored depending on pixel changes between consecutive frames (404). The stored pixel information from multiple subsets of individual pixels of the frame renderings can collectively reflect time and intensity parameters that the frame renderings have driven the set of pixels.
