Description
Technical field
The utility model relates to a kind of LCDs, particularly relates to a kind of LCDs that can improve contrast.
Background technology
Along with development of science and technology, people are more and more higher to the requirement of LCD (LCD), and contrast becomes a leading indicator of LCDs performance improvement.
See also Fig. 1, it is the cut-open view of prior liquid crystal display, and described LCDs has a top glass substrate 10 ', one lower glass substrate 20 ', is equipped with silicon dioxide SiO on the lower surface of this top glass substrate 10 ' and the upper surface of lower glass substrate 20 '
2Layer 70 ' and polyimide PI guide layer 80 '.On the polyimide PI of lower glass substrate 20 ' guide layer 80 ', be covered with black film 90 '.This black film 90 ' is a kind of resin, places in the LCD box, covers black film 90 ' and promote the universal method of the contrast of LCD significantly for using additional materials at present on polyimide PI guide layer 80 '.
But there is following defective in the contrast of using black film to promote LCD: black film is made needs at first on the one hand increases special-purpose photoresist spinner, and such machine just needs the Renminbi hundreds of thousands, the production cost height; The material of black film own is very expensive on the other hand, and this material mainly is Japanese and Taiwan produces, and obtaining comparatively of material bothers; Secondly, black film is bigger to the electrical property influence of LCD, when polyimide PI guide layer 80 ' is carried out hot setting, makes the black film charing easily and short circuit when follow-up, thereby makes the electric current of the circuit in the LCD become big undesiredly; Once more, because black film places in the LCD box, the thickness of resin black film reaches about 1 micron usually, so can produce a very large impact LCD box thickness evenness, is not suitable for more for the thick demanding product of box especially.
The utility model content
It is low, anti-interference and can improve the LCDs of contrast that the technical matters that the utility model mainly solves provides a kind of production cost.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of LCDs is provided, comprise a top glass substrate and a lower glass substrate, edge between described top glass substrate and the lower glass substrate is provided with supporter, and be sealed with liquid crystal between the described upper and lower glass substrate, the inboard of described upper and lower glass substrate all is covered with silicon dioxide SiO
2Layer, polyimide PI guide layer, the outside of described upper and lower glass substrate has last polaroid respectively and reaches polaroid down, described LCDs comprises a plurality of pixels, evenly be provided with the shading metal film that one deck replaces the resin black film at least one described glass substrate, be formed with the light hole of the described pixel of a plurality of correspondences on this metal film.
Wherein, described metal film is arranged on the outside of top glass substrate, and is arranged on top glass substrate and described going up between the polaroid.
Wherein, described metal film is arranged on the inboard of top glass substrate, and is arranged on top glass substrate and described silicon dioxide SiO
2Between the layer.
Wherein, describedly state the inboard that metal film is arranged on lower glass substrate, and be arranged on lower glass substrate and described silicon dioxide SiO
2Between the layer.
Wherein, described metal film is arranged on the outside of top glass substrate, and is arranged on top glass substrate and described down between the polaroid.
Wherein, described polyimide PI guide layer places the outermost layer of the inboard of described upper and lower glass substrate.
Wherein, the thickness range of described metal film is between 0.1 micron to 0.3 micron, is preferably 0.2 micron.
Wherein, described metal film is chromium Cr.
The beneficial effects of the utility model are: be different from LCDs in the prior art need use the plated resin black film to improve dot matrix and contrast and cause the production cost height, big and influence the thick inhomogeneity situation of box to the electrical property influence of LCD.The utility model LCDs is provided with dot matrix and the contrast that metal film improves LCDs, and production cost is low; Metal film is arranged at least one glass substrate of LCDs, and silicon dioxide SiO is arranged
2The protection of layer can be avoided making the black film charing easily when follow-up polyimide PI guide layer hot setting and short circuit makes the electric current of the circuit in the LCD become big situation undesiredly.
The utility model LCDs is used and is covered metal film, and owing to metal membrane material is easy to obtain, so the each side cost is lower; And the thickness of metal film is little, generally only has an appointment 0.2 micron, so little to the influence of LCD box uniform thickness.

Embodiment
By describing technology contents of the present utility model, structural attitude in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
See also Fig. 2, be the cut-open view of first kind of embodiment of the utility model LCDs, comprise top glass substrate 10, lower glass substrate 20 and be sealed in top glass substrate 10 and lower glass substrate 20 between liquid crystal 30.
The edge of described top glass substrate 10 and lower glass substrate 20 is provided with supporter 40, by being bonded together with an end on described upper glass surface 10, an end on lower-glass surface 20 respectively in conjunction with the two ends of glue with described supporter 40.Described supporter 40 supports top glass substrate 10 and lower glass substrate 20 at interval and the formation gap.Described liquid crystal 30 is sealed in the described gap between top glass substrate 10 and the lower glass substrate 20.
