Abstract
Official abstract text for this publication.
This disclosure is related to compensation of micro devices based on cartridge information.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method to calculate a compensation value for variation in micro-devices transferred from different cartridges into system substrate comprising: using a micro device position to fetch cartridge parameters; using the cartridge parameters along with a micro device value to calculate the compensation value; and performing compensation for a plurality of the cartridge parameters using blocks in series or parallel. 2 . The method of claim 1 , wherein the micro device value is converted into a brightness value and the cartridge parameters are passed to a compensation block where it converts the brightness value into compensation value. 3 . The method of claim 1 , wherein the blocks include a block to store the cartridge parameters. 4 . The method of claim 3 , wherein the blocks include a block to extract the cartridge parameters associated with the cartridge from which the micro device is extracted. 5 . The method of claim 4 , wherein the blocks include a value calculator block to generate a comp value. 6 . The method of claim 5 , wherein the value calculator block includes a lookup table. 7 . The method of claim 5 , wherein the value calculator block includes a computation block. 8 . A compensation method for a micro device in a system substrate comprising: providing different micro devices where at least the output of a micro device different than the micro device is adjusted to compensate for a parameter in said micro device; calculating a brightness value of the micro device; calculating a compensation value from different micro devices based on a cartridge parameter and micro device position, wherein the compensation values are added to the brightness value; and the modified brightness is used to calculate a programming value. 9 . The compensation method of claim 8 , wherein the programming value is extracted from gamma curve, pixel uniformity, and temperature value. 10 . The compensation method of claim 8 , wherein the brightness value is extracted from a gamma curve.
