摘要： A method of compensating uniformity of an EL device, having a plurality of light-emitting elements, including providing the EL display; and measuring the performance of one or more light-emitting elements at three or more different code values. At least two different groups of code values are formed from the three or more code values, while calculating a linear transformation for converting an input signal to a compensated signal from the performance measurements for each of the groups. Subsequently, the difference between the measured performance and compensated signal is calculated over the range of code values for each of the groups; while the linear transformation, having a preferred difference, is selected. Additionally an input signal is received and employed with the selected linear transformation to calculate a compensated signal to drive the EL display.

摘要： An apparatus for detecting variations in light output of an electroluminescent (EL) device is described. The EL device includes a transparent substrate having a first edge extending in a first direction and a plurality of EL emitters disposed over the face of the substrate in the first direction, and some of the light emitted by each EL emitter travels through the substrate and out of the first edge. A light sensor physically separated from the first edge senses the light travelling out of the first edge. A controller stored first sensed light at a first time and second sensed light at a later second time and computes a variation in light output of one or more of the EL emitters in the EL device using the stored first sensed light and second sensed light.
