摘要:
The invention relates to a method for manufacturing a device comprising an organic light-emitting diode including at least one electrode comprising an electrically conductive stack of thin films deposited onto a substrate, wherein the deposition of said stack includes the following steps: depositing, onto said at least one surface of said substrate, a stack of thin films including at least one thin film of silver between at least two thin films; and heat-treating the at least one coated surface by means of at least one laser beam emitting in at least one wavelength of 500 to 2000 nm, such that the sheet resistance of the stack is reduced by at least 5%.

The invention relates to a method for producing a substrate provided with a coating on at least a portion of at least one of the surfaces thereof, including a step of depositing said coating onto said substrate, then a step of heat-treating said coating using pulsed or continuous laser radiation focused on said coating in the form of at least one laser line, the wavelength of which is within a range of 400 to 1500 nm, said heat treatment being configured such that a relative displacement movement is generated between the substrate and the or each laser line, the speed of which is at least 3 meters per minute, the or each laser line having a beam quality factor (BPP) of at most 3 mm mrad, and, measured at the point at which the or each laser line is focused on said coating, a linear power divided by the square root of the duty cycle of at least 200 W/cm, a length of at least 20 mm, and a distribution of widths along the or each line such that the mean width is at least 30 micrometers and the difference between the largest width and the smallest width is at most 15% of the value of the mean width.

The invention relates to a method for obtaining a substrate (1) provided with a coating (2) on at least one of its faces, said method comprising a step of depositing said coating (2), followed by a step of heat-treating said coating by means of a main laser radiation (4). The method is characterised in that at least part (5, 14) of the main laser radiation (4) transmitted through said substrate (1) and/or reflected by said coating (2) is redirected towards said substrate in order to form at least one secondary laser radiation (6, 7, 18).
