Title:
OLEDディスプレイにおける不均一性と明るさの測定
Document Type and Number:
Japanese Patent JP2008502108
Kind Code:
A
Abstract:
A detection system for the detection of brightness and uniformity variations in an OLED display, comprising: a two-dimensional OLED display having a pre-defined group of light-emitting elements distributed across the display; a two-dimensional imager; optical elements arranged so that the imager is exposed to all of the light-emitting elements in the predefined group of light-emitting elements of the OLED display simultaneously and at a magnification such that each light-sensitive sensor element records the light output from no more than one light-emitting element; and a controller to control the OLED display and cause each of the light-emitting elements of the predefined group of light-emitting elements to illuminate and the imager to acquire images of the illuminated light-emitting elements in the OLED display. The invention is further directed towards a method for the measurement of brightness and uniformity variations in light-emitting elements of an OLED display.
