Patent number: 10935694Abstract: Light scattering particles made of TiO2, BaSO4, SiO2, or Al2O3 have been used in a QD layer of a QD-LED for enhancing luminous intensity. However, the light scatters are found to decline the light conversion efficiency of the QD layer. In view of that, the present invention particularly discloses a light conversion material with high conversion efficiency for use in the QD-LED. The light conversion material mainly comprises a polymer matrix, a plurality of 3D photonic crystals dispersed in the polymer matrix, and a plurality of quantum dots dispersed in the polymer matrix, wherein each of the plurality of 3D photonic crystals is formed by applying a self-assembly process to a plurality of polymer beads. Moreover, a variety of experimental data have proved that, this light conversion material indeed exhibits outstanding photoluminescence intensity and light conversion efficiency both superior than that of the conventionally-used QD layer.Type: GrantFiled: June 23, 2018Date of Patent: March 2, 2021Inventors: Hsueh-Shih Chen, Shih-Jung Ho

Patent number: 9061564Abstract: An active vehicle with variable inclination mechanism is provided. The active vehicle with variable inclination mechanism comprises a linear slide mechanism, two sets of longitudinal interlocking mechanism, a steering control mechanism, and a control unit. The linear slide mechanism comprises a reciprocating action member. A lateral displacement of the reciprocating action member drives the longitudinal interlocking mechanism to produce a displacement along a longitudinal direction while a torque is applied at the steering control mechanism. The wheels are driven to move along an opposite longitudinal direction and to form an inclination. Using the active vehicle with variable inclination mechanism can provide a real-time inclination force while rounding a corner as well as increase the safety. Besides, the driver can easily get on/off the vehicle when the vehicle is stationary and the reciprocating action member is locked at the stationary position of the vehicle.Type: GrantFiled: December 18, 2013Date of Patent: June 23, 2015Assignee: Automotive Research & Testing CenterInventors: Chao-Chih Yu, Chih-Jung Yeh, Jin-Yan Hsu, Jiun-Jie Chen, Shih-Jung Ho
