Description
Technical field
The present invention is relevant with display device, particularly a kind of polycrystalline transparent ceramic display panel.
Background technology
Such equipment can be seen along with liquid crystal display is used on various handheld apparatus widely; and a protective seam all can be set on the surface of liquid crystal display come as protection in order to avoid liquid crystal display is damaged because of collision or scratch; come as protection with strengthening (tempering) glassy layer at present; but along with the change of manufacturing capacity, brought into use now the sapphire display panel (SapphireLaminate) of monocrystalline to come as protective seam.Due to the excellent specific property that hardness is very high and transmittance is high of the sapphire display panel of monocrystalline itself; so use the sapphire display panel of monocrystalline can provide better protected effect than use strengthening (tempering) glass as protective seam, also can some shortcoming but relative.The sapphire display panel of monocrystalline itself is cut by the crystallization post of monocrystalline to be ground again, so to sapphire display board be made cambered surface or the nonplanar state such as curved surface or sphere time just first must cut bulk crystal attrition process in addition again, way Hui Mao so takes a lot of materials and time.Moreover, characteristic due to monocrystalline is that whole crystal all has identical physical properties so can not adjust in the transparency of display panel, therefore will be restricted on the polarization effect and transparency of display board, be difficult to change to some extent on the display panel of single crystal.
Summary of the invention
Because above-mentioned shortcoming, the object of the present invention is to provide a kind of can reduce process time and avoid the polycrystalline transparent ceramic of material consumption to show face show plate.
