  • Publication number: 20250196258
    Abstract: A laser processing equipment includes a laser unit and a carrier. The laser unit includes a pulsed laser light source, a vibration mirror, a mask, and a focusing module. The pulsed laser light source provides a pulsed laser beam. The vibration mirror turns the pulsed laser beam. The mask receives the pulsed laser beam. The mask has multiple openings distributed along a first direction. The openings are used to allow the pulsed laser beam to pass through. The focusing module respectively focuses the pulsed laser beam passing through the openings into multiple laser spots distributed along the first direction. The carrier carries multiple processing elements. The processing elements are disposed corresponding to distribution positions of the laser spots along the first direction. A laser processing method is also provided.

  • Publication number: 20250073809
    Abstract: A laser processing apparatus provides a laser unit, a vibration mirror module, a focusing module, and a processing platform. The laser unit emits a laser pulse beam. The vibration mirror module, positioned on the path of the laser pulse beam, reflects the laser pulse beam and has a first mode and a second mode configured to reflect the laser pulse beam into a first beam while the module is in the first mode or alternatively, into a second beam while the module is in the second mode. The first beam and the second beam travel in different directions. The focusing module receives the second beam reflected by the vibration mirror module in the second mode and focuses the second beam onto a focus. The processing platform is positioned at the focus to bear a to-be-processed device, upon which the second beam is cast.

  • Publication number: 20250041967
    Abstract: A laser processing apparatus including a laser light source, a polarizing beam splitter, a first reflective mirror, a second reflective mirror, and a polarizing beam combiner is disclosed. The laser light source is configured to generate a laser light. The polarizing beam splitter is configured to divide the laser light into a first beam and a second beam. The first reflective mirror is configured to reflect the first beam. The second reflective mirror is configured to reflect the second beam. The polarizing beam combiner is disposed on a path of the first beam reflected by the first reflective mirror and on a path of the second beam reflected by the second reflective mirror. An optical axis of the polarizing beam combiner is not parallel to the first beam. The polarizing beam combiner is configured to guide the first beam and the second beam.

  • Patent number: 10025133
    Abstract: A liquid crystal display device comprises an array substrate, a liquid crystal layer, and a color filter substrate. The liquid crystal layer is disposed between the array substrate and the color filter substrate. The color filter substrate includes a base material, an overcoat, a color filter layer and first transparent electrode patterns. The overcoat is disposed between the base material and the liquid crystal layer. The color filter layer is disposed between the base material and the overcoat, and includes color filter elements separated from each other and black matrixes. The first transparent electrode patterns are disposed between the overcoat and the liquid crystal layer, and are separated from each other and opposed to the black matrixes. A width of each of the black matrixes is equal to or greater than a width of each of the first transparent electrode patterns.
