Patent number: 10895641Abstract: A proximity sensing device which is disposed under the OLED panel and has an emitting module and a receiving module, is provided. The emitting module can emit an invisible light which has a peak wavelength not less than 1000 nm. The receiving module is disposed adjacent to the emitting module and can receive a reflecting light from the reflected invisible light. Therefore, the invisible light passing through the OLED panel will not cause a bright spot on the panel.Type: GrantFiled: March 25, 2019Date of Patent: January 19, 2021Assignee: Everlight Electronics Co., Ltd.Inventors: Shih-Wen Lai, Yi-Ting Huang, Jing-Hong Lai, Chih-Hao Hsu, Chia-Wei Yang, Chih-Min Lin, Chieh-Yu Kang, Kuang-Mao Lu, Jian-Hong Fan

Patent number: 10683454Abstract: The present invention relates to a phosphor, a method for preparing the phosphor, an optoelectronic component, and a method for producing the optoelectronic component. The phosphor has the following general formula: La3(1?x)Ga1?yGe5(1?z)O16: 3xA3+, yCr3+, 5zB4+, where x, y, and z do not equal to 0 simultaneously; A represents at least one of Gd and Yb; B represents at least one of Sn, Nb, and Ta. For the phosphor, its emission spectrum is within a red visible light region and a near-infrared region when excited by blue visible light, purple visible light or ultraviolet light; and it has a wide reflection spectrum and a high radiant flux. Therefore, it can be used in optoelectronic components such as LEDs to meet requirements of current medical testing, food composition analysis, security cameras, iris/facial recognition, virtual reality, gaming notebook and light detection and ranging applications.Type: GrantFiled: October 19, 2018Date of Patent: June 16, 2020Assignee: Everlight Electronics Co., Ltd.Inventors: Veeramani Rajendran, Mu-Huai Fang, Ru-Shi Liu, Ho Chang, Kuang-Mao Lu, Yan-Shen Lin, Chieh-Yu Kang, Gabriel Nicolo A.

Patent number: 10680145Abstract: The present disclosure provides an LED package structure and a method for manufacturing the LED package structure. The LED package structure includes: a chip scale package (CSP) light emitting element and a shading layer, where the CSP light emitting element includes a light emitting chip, and the light emitting chip includes an electrode group located on a bottom surface of the light emitting chip, the shading layer is disposed on a bottom surface and/or a side surface of the CSP light emitting element. An LED package structure according to the present disclosure solves a problem that the blue light leaking from the bottom surface of the LED chip interferes with the emission color of the CSP emitting device, and reduces the luminous efficiency of the emitting device.Type: GrantFiled: August 3, 2018Date of Patent: June 9, 2020Assignee: EVERLIGHT ELECTRONICS CO., LTD.Inventors: Ke-Hao Pan, Sheng-Wei Chou, Yi-Sheng Lan, Chia-Fong Chou, Chung-Chuan Hsieh, Jen-Hao Pan, Hao-Yu Yang, Chieh-Yu Kang, Tzu-Lun Tseng
