Abstract
Apparatus and methods for repairing display devices of a type that include a first substrate having a plurality of signal lines formed thereon and/or a second substrate having a plurality of color filters formed thereon include a laser that radiates laser light having a wavelength in a range of from about 750 to about 850 nm, or alternatively, of from about 1000 to about 1100 nm, and a pulse width of femtoseconds (10seconds) to picoseconds (10seconds) and arranged such that the laser light can be focused on selected ones of the signal lines and/or color filters. The apparatus enables repairs to be effected on the display device during any one of several manufacturing test processes using only a single laser apparatus, without the need for additional or different repair devices for each test process.
