  • Patent number: 7956960
    Abstract: A display panel and a manufacturing method are disclosed. The method is to thin the thickness of a pair of transparent substrates for the display panel by grinding or lapping only, or grinding with simplified polishing, so that at least one of the outer surface of the transparent substrates has Haze substantially less than 90% and a profile arithmetic mean roughness ranged from about 0.02 ?m to about 0.66 ?m.

  • Patent number: 7746440
    Abstract: A flat display panel includes a first substrate, a second substrate opposite to the first substrate, a sealant disposed between the first and second substrates. The sealant, the edge of the inner surface of the first substrate, and the edge of the inner surface of the second substrate form a space, and the flat display panel further includes a protection layer disposed inside the space so as to reinforce the structural strength of the flat display panel.

  • Publication number: 20090258565
    Abstract: The present invention provides a method for manufacturing display panel with substrates having different thickness. The display panel manufacturing method includes assembling a first substrate and a second substrate, positioning the anti-etching layer on the outer surface of the first substrate and etching the substrates at the first etching process. Because the anti-etching layer is disposed on the first substrate, the first substrate is protected by the anti-etching layer from being etched or later etched. Simultaneously, the second substrate is etched to reduce its thickness in order to adjust the thickness difference between the first substrate and the second substrate.

    Abstract: A thinned substrate for a display panel and manufacturing process thereof are provided. The thinned substrate includes an inorganic transparent plate and a supporting layer to form a stacked layer. The supporting layer avails improvement of structure strength of the thinned substrate and reliability of the thinned substrate. A ratio between thickness of the inorganic transparent plate and thickness of the supporting layer is substantially less than or substantially equal to 4. A total thickness of the stacked layer is substantially less than or substantially equal to 20 mm. Bending strength of the stacked layer is substantially greater than or substantially equal to 150 MPa.
