METHOD AND APPARTUS FOR UNIFORMITY AND BRIGHTNESS CORRECTION IN A DISPLAY |
摘要 |
A method for the correction of average brightness or brightness uniformity variations in electroluminescent (EL) displays comprising: a) providing an EL display having one or more light-emitting elements responsive to a multi-valued input signal for causing the light-emitting elements to emit light at a plurality of brightness levels; b) measuring the brightness of each light-emitting element at two or more, but fewer than all possible, different input signal values; c) employing the measured brightness values to estimate a maximum input signal value at which the light-emitting element will not emit more than a predefined minimum brightness and the rate at which the brightness of the light-emitting element increases above the predefined minimum brightness in response to increases in the value of the input signal; and d) using the estimated maximum input signal value at which the light-emitting element will not emit light more than the predefined minimum brightness and the rate at which the brightness of the light-emitting element increases above the predefined minimum brightness in response to increases in the value of the input signal to modify the input signal to a corrected input signal to correct the light output of the light-emitting elements.
