Patent number: 11935985Abstract: A micro light-emitting diode (LED) display panel including a substrate, a first micro LED, a first light-shielding wall, a second micro LED, and a second light-shielding wall is provided. The substrate includes a plurality of pixel regions arranged in an array. The first micro LED is disposed on one of the pixel regions of the substrate. The first light-shielding wall is disposed on the substrate and located beside the first micro LED. The second micro LED is disposed on the one of the pixel regions of the substrate and located beside the first micro LED. The second light-shielding wall is disposed on the substrate and located beside the second micro LED. A light wavelength of the first micro LED is different from a light wavelength of the second micro LED. A height of the first light-shielding wall is smaller than a height of the second light-shielding wall.Type: GrantFiled: August 23, 2021Date of Patent: March 19, 2024Assignee: PlayNitride Display Co., Ltd.Inventors: Sheng-Yuan Sun, Loganathan Murugan, Po-Wei Chiu

Patent number: 11923399Abstract: A micro light-emitting diode display panel includes a substrate, at least one light-emitting element, a reflective layer and a light-absorbing layer. The at least one light-emitting element is disposed on the substrate to define at least one pixel, and each light-emitting element includes micro light-emitting diodes. The reflective layer is disposed on the substrate and located between the micro light-emitting diodes. The reflective layer has cavities surrounding the micro light-emitting diodes, such that a thickness of a portion of the reflective layer close to any one of the micro light-emitting diodes is greater than a thickness of a portion of the reflective layer away from the corresponding micro light-emitting diode. The light-absorbing layer is at least disposed in the cavities of the reflective layer.Type: GrantFiled: March 31, 2021Date of Patent: March 5, 2024Assignee: PlayNitride Display Co., Ltd.Inventors: Sheng-Yuan Sun, Loganathan Murugan, Po-Wei Chiu, Yun-Li Li

Patent number: 11916170Abstract: A micro-light-emitting diode chip includes an epitaxial structure, an electrode, a transparent structure, and a reflection layer. The epitaxial structure has a light exit surface, a back surface opposite to the light exit surface, and a sidewall surface. The sidewall surface is connected to the light exit surface and the back surface. The electrode is electrically coupled to the epitaxial structure. The transparent structure has an inner surface and an outer surface opposite to the inner surface. The inner surface is connected to the sidewall surface. A distance between the outer surface and the inner surface on a plane where the back surface is located is less than a distance between the outer surface and the inner surface on a plane where the light exit surface is located. The reflection layer is in direct contact with the outer surface. A micro-light-emitting diode display is also provided.Type: GrantFiled: September 13, 2021Date of Patent: February 27, 2024Assignee: PlayNitride Display Co., Ltd.Inventors: Sheng-Yuan Sun, Loganathan Murugan, Po-Wei Chiu

Patent number: 11754771Abstract: An optical virtual push button touch panel includes a substrate (10), a light emitting member (11), a light guide plate (12), a light permeable plate (13), and a touch control sensing member (14). The substrate is provided with a mounting slot (100). The light emitting member is mounted in the substrate. The light guide plate defines multiple light guide structures (120). The light permeable plate is mounted on the substrate. The touch control sensing member is located between the light permeable plate and the light guide plate and defines multiple contact zones (140) aligning with the light guide structures respectively. One of the contact zones produces a coupling capacitance through the light permeable plate and drives the light emitting member to generate the light source, and one of the light guide structures converges the light source toward one of the contact zones.Type: GrantFiled: December 16, 2022Date of Patent: September 12, 2023Assignee: AXIOMTEK CO., LTD.Inventors: Tien-Hon Hu, Po-Yuan Chiu, Yi-Kai Kao
