AI Technical Summary
Technical Problem
Existing smoked cover plates have high manufacturing costs and low hardness, which affects product competitiveness.
Method used
Semi-transparent inks are produced on glass cover plates using slot coating or spin coating methods. Combined with a protective layer and a viewing window ink, the transmittance is achieved by controlling the ink thickness or creating small holes in the ink. Transparent materials such as silicon dioxide, silicon nitride, niobium oxide, or titanium oxide are used as the protective layer.
Benefits of technology
This reduces the production cost of smoked covers while increasing their hardness, thus enhancing product competitiveness.

Abstract
The invention discloses a manufacturing method of a smoked cover plate and a hidden liquid crystal display screen. The manufacturing method of the smoked cover plate comprises the following steps: step 1, providing a glass cover plate; 2, a layer of semi-permeable printing ink is manufactured on the glass cover plate in a crack coating or spin coating mode, the transmittance of the semi-permeable printing ink is achieved by controlling the thickness of the semi-permeable printing ink or manufacturing small holes in the position of the semi-permeable printing ink, and the diameter of the small holes ranges from 10 micrometers to 100 micrometers; 3, manufacturing a protective layer on the semi-permeable printing ink; and 4, window printing ink is manufactured on the protective layer. Spin coating uniformity is superior to crack coating, but a large amount of spin coating materials are wasted, as the spin coating is whole-surface coating, the crack coating can be selected in a specific area, the edge of the glass cover plate needs to be wiped during spin coating, and the conveying mode of the glass cover plate, such as edge clamping, is required. The smoking cover plate manufactured by the method is low in cost and relatively high in hardness, so that the product competitiveness of the smoking cover plate is improved.
