Latest Patents

Two of Hiroya's notable patents include advancements in liquid-crystal display devices and methods for laminating optical sheets.

The first patent describes a liquid-crystal display device designed to attach an optical element to a liquid-crystal display panel with high positional accuracy. This patent specifically focuses on minimizing the enlargement of the non-display region caused by the formation of markers on the panel while controlling fabrication costs. The design features a main substrate, an opposite substrate, and liquid crystal captured between them, with a polarizer plate applied to the opposite substrate. Markers that assist in the attachment of optical elements are strategically placed to overlap with the polarizer in a non-display area, coupled with regulators that align liquid crystal molecules for optimal light passage.

The second patent outlines an optical sheet laminating method that achieves high accuracy and quality during the optical sheet and display panel laminating step. This innovation involves reading the contact areas between the optical sheet and the holding head, ensuring precision as the optical element face of the optical sheet makes contact. By irradiating light to the contact areas from a no-optical-element face, Hiroya's method accurately gathers positional information based on the distribution of reflected light.
