Problems solved by technology

[0003] The energy distribution of the laser is usually a Gaussian distribution such as figure 1 As shown, this distribution method is very uneven. In order to achieve the purpose of uniform scanning, most methods choose to filter out the areas where the energy density is too large or too sm...

Embodiment Construction

[0043] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples cited are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0044] Such as figure 2 As shown, the embodiment of the present invention provides a laser processing method, including the following implementation steps:

[0045] S1, the control component 5 controls the laser 1 to emit laser light;

[0046] S2, the control component 5 controls the scanning component 2 to perform rectangular scanning on the processed object; during scanning, the scanning uniformity is controlled by controlling the size of the horizontal scanning line spacing L.

[0047] In the above-mentioned embodiment, measures such as interception and shielding are not taken for the laser, so that all the energy of the laser is loaded on the processed object; by setting the scanning line spacing L, the energy distribution of...

Abstract

The invention relates to the field of laser application, and discloses a laser processing method. The laser processing method comprises the following implementation steps that S1, a control componentcontrols a laser device to output laser; and S2, the control component controls a scanning component to perform rectangular scanning on a processed object; and during scanning, the scanning uniformityis controlled by controlling the size of the horizontal scanning line spacing L. By setting the scanning line spacing L, the energy distributions of the scanning lines are crossed, and the transversescanning lines are parallel, so that the energy borne by an intermediate processing part is the average of the scanning energy of the adjacent scanning lines, and the effect of energy uniformizationis achieved on the basis of not wasting energy. The invention further discloses a laser processing system.

Description

Technical field [0001] The invention relates to the field of laser applications, in particular to a laser processing method and system. Background technique [0002] In the field of laser application, especially in the field of laser repair, it is often necessary to use laser to scan the repair area uniformly. For example, in the repair of bright spot defects of liquid crystal panels, it is necessary to use laser scanning to repair the pixels needed to make them darker. Among them, excessive concentration of energy in some areas will damage the bottom layer of the color filter, and the liquid crystal will flow to the color filter layer. As a result, serious failures can be caused. If the energy in some areas is too low, the repair fails and needs to be repaired. Therefore, uniform laser scanning is essential. [0003] The energy distribution of laser is usually Gaussian, such as figure 1 As shown, this distribution method is very uneven. In order to achieve the purpose of uniform ...
