Latest Patents

One of Sento's latest patents involves a liquid crystal display device that features a TFT substrate and a counter substrate bonded together by a sealing material, with liquid crystal sandwiched between the substrates. A front window with a black border print is bonded to the liquid crystal display panel using a UV curable resin. The liquid crystal is filled using a drop method, and the thickness of the TFT substrate and counter substrate is reduced to about 0.2 mm through polishing. This design ensures that the inner end of the black border print is positioned inside the sealing material's inner end, preventing deformation of the counter substrate due to stress during the curing process of the UV curable resin. This innovation helps to prevent yellow discoloration around the display area.
