Latest Patents

One of his latest patents is focused on a high-definition cathode-ray tube and its manufacturing method. This innovation addresses the issue of light/dark line patterns that can occur during the operation of color cathode-ray tubes. The method involves exposing light that has passed through a correction lens, which consists of both continuous and discontinuous lenses. This light is then irradiated onto a photosensitive film located on the inner surface of the face panel of the tube via a shadow mask. The exposed photosensitive film is used as a mask to form fluorescent dot patterns on the face panel's surface. The design of the correction lens includes multiple light incident planes arranged in a matrix form, allowing for precise light refraction and projection.
