The outer surface includes at least one outer notch between the inward extending contacting features. The edge holders and outer notch(es) are for each acting as hinge points opening or pinching depending on a direction of force on the optical mount for responding with flexure when there is a dimensional change in the crystal, mount material, or the housing. | 2019-09-05 |

20190271865 | Method for Manufacturing LCD Panel - The present disclosure provides a method for manufacturing a liquid crystal display (LCD) panel, including cleaning the first substrate by a hydrophobic surface cleaning material and cleaning the second substrate by a hydrophilic surface cleaning material; heating the first substrate and the second substrate at a high temperature; bonding the first substrate with the second substrate to from a liquid crystal cell; and irradiating the liquid crystal cell with UV light to form a first thin film on the surface of the first substrate and to form a second thin film on the surface of the second substrate. | 2019-09-05 |
20190271866 | ANTI-PEEPING DEVICE, ANTI-PEEPING DISPLAY AND CONTROL METHOD - An anti-peeping device, an anti-peeping display, and a control method. The anti-peeping device comprises an external light source, a grating mirror structure, and a first controller coupled to the grating mirror structure. The external light source is configured to emit light towards the grating mirror structure, and the first controller is configured to control the grating mirror structure to rotate such that light emitted from the external light source towards the grating mirror structure is reflected to a first direction by the grating mirror structure, the first direction deviating from a normal perpendicular to the horizontal plane of the grating mirror structure. | 2019-09-05 |
