20200026105 | PHOTONIC TRANSMITTER - A photonic transmitter is provided, including a laser source including a first waveguide made of silicon and a second waveguide made of III-V gain material, the waveguides being separated from each other by a first segment of a dielectric layer; and a phase modulator including a first electrode made of single-crystal silicon and a second electrode made of III-V crystalline material, separated from each other by a second segment of the dielectric layer, where a thickness of the dielectric layer is between 40 nm and 1 μm, where a thickness of a dielectric material in an interior of the first segment is equal to the thickness of the dielectric layer, and where a thickness of the dielectric material in an interior of the second segment is between 5 nm and 35 nm, a rest being formed by a thickness of semiconductor material. | 2020-01-23 |
20200026106 | EWRITER WITH ENHANCED LINE ACUITY - A liquid crystal writing device with enhanced line acuity includes the following features. Included is a front writing surface. A liquid crystal layer includes a dispersion of cholesteric liquid crystal and polymer, wherein a reflectance of the cholesteric liquid crystal changes in response to pressure applied to the front writing surface so as to form an image on the liquid crystal layer. The liquid crystal layer is disposed between electrically conductive layers. A second of the electrically conductive layers is more distal from the front writing surface than a first of the electrically conductive layers is from the front writing surface. A backing supports the pressure applied to the front writing surface. An adhesive layer is disposed between the second of the electrically conductive layers and the backing. A line acuity of the image has a value of not more than 3.0 determined according to the Line Acuity Measurement Method of this disclosure. | 2020-01-23 |
20200026107 | DISPLAY PANEL AND DISPLAY DEVICE - A display panel and a display device are described herein. The display panel includes a first substrate, a second substrate disposed opposite to the first substrate, and a sealant frame formed between the first substrate and the second substrate. The sealant frame is made of an adhesive substance hardened through a self volatile hardening process or a thermosetting process. | 2020-01-23 |
