Realizing the technical scheme of above-mentioned purpose is:A kind of colored filter, including CF substrates, flatness layer and filter layer, The filter layer is located between the CF substrates and flatness layer;Wherein, the filter layer includes transparent area and shading region, the screening It is provided with light area and metal grill shape, for shading is patterned by conductive metal film, the metal grill includes multiple The touch control electrode layer block insulated each other, each touch control electrode layer block is connected to touch-control control chip by wire.

In a preferred embodiment of the present invention, the junction between the touch control electrode layer block is the light leak area of insulation.

In a preferred embodiment of the present invention, black shading material is filled with the light leak area.

In a preferred embodiment of the present invention, the black shading material is polystyrene material.

In a preferred embodiment of the present invention, the light leak area is into matrix arrangement.

Second object of the present invention is:A kind of display device is provided.

Realizing the technical scheme of above-mentioned purpose is:A kind of display device, including colored filter, in being the first technical scheme Described colored filter;TFT substrate;It is located at the liquid crystal layer between the TFT substrate and the colored filter;It is sequentially arranged at The upper polaroid and cover plate of the CF upper surface of base plate;And be sequentially arranged at the TFT substrate lower surface down polaroid and Backlight.

In a preferred embodiment of the present invention, described display device includes viewing area and non-display area, the metal grill Located at the viewing area.

In a preferred embodiment of the present invention, the lower surface of the flatness layer is distributed with for supporting the CF substrates and described The support column of TFT substrate.

In a preferred embodiment of the present invention, the support column material therefor is polystyrene material.

It is an advantage of the invention that:The filter layer of the present invention and colored filter and display device with the filter layer, Original black matrix" is substituted with metal grill, material cost has been saved.Touch controllable function is integrated in display device, taken simultaneously Disappeared screen layer, saves material cost and holistic cost, reduces processing procedure difficulty, reduces the thickness of display device.Using Metal grill does touch control electrode, while touch-control performance is improved, thoroughly prevents undulatory interference fringe (i.e. Moire fringe) Generation.

Embodiment

The explanation of following examples is the particular implementation implemented to illustrate the present invention can be used to reference to additional schema Example.The direction term that the present invention is previously mentioned, such as " on ", " under ", "front", "rear", "left", "right", " top ", " bottom ", be only With reference to the direction of annexed drawings.Therefore, the direction term used is to illustrate and understand the present invention, and is not used to limit this hair It is bright.

Embodiment 1, as shown in figure 1, a kind of filter layer, including transparent area and shading region, shading region is provided with by metallic conduction Thin-film patterning formation, metal grill for shading, the metal grill instead of what is formed after black matrix", patterning Metal grill 11 includes touch control electrode layer block 111 and multiple gaps 112 (the light leak area) of multiple mutually insulateds, the touch control electrode The junction of layer block 111 is insulated by the gap 112, and the touch control electrode layer block 111 is connected to touch-control by wire and controls core Piece.

In the present embodiment, the metal grill 11 set using matrix form replaces the black matrix" that original matrix form is set, Because the purpose of black matrix" is shading, opaque metal grill 11 can also reach the purpose of shading.

In the specific implementation, in the present embodiment, wire netting that metal grill conductive film patterning shapes, for shading Lattice 11 can have gap 112, and the purpose in the gap 112 is that the metal grill 11 in whole face is divided into several touch control electrode layer blocks 111., can be using the black lightproof material used in original black matrix" to prevent the light leak of gap 112 due to the gap 112 meeting light leak Matter or black polystyrene material are filled to gap 112.

Embodiment 2, as shown in Fig. 2 a kind of colored filter, including CF substrates 2, flatness layer 3, in addition to embodiment Filter layer 1 described in 1, wherein, the filter layer 1 is located between the CF substrates 2, flatness layer 3.When needing colorized optical filtering , it is necessary to touch control electrode be drawn by wire when piece is assembled on the devices such as display screen, and be connected to drawing for touch-control control chip On pin.

Embodiment 3, as shown in Figure 3.A kind of display device, including colored filter, liquid crystal layer 4, TFT substrate 5, lower polarisation Piece 6, backlight 7, upper polaroid 8 and cover plate 9.

Specifically, the colored filter in the present embodiment is the described colored filter in embodiment 2.4 groups of liquid crystal layer Lower surface loaded on the flatness layer 3;Wherein, support column 31 is provided between the flatness layer and the liquid crystal layer.Support column 31 For supporting the CF substrates and the TFT substrate.The support column 31 is polystyrene material.

TFT substrate 5 is assembled in the lower surface of the liquid crystal layer 4;Down polaroid 6 is assembled in the following table of the TFT substrate 5 Face;Backlight 7 is assembled in the lower surface of the down polaroid 6;Upper polaroid 8 is assembled in the upper surface of the CF substrates 2;Cover plate 9 are assembled in the upper surface of the upper polaroid 8.

In this example it is shown that device includes viewing area 12 and non-display area 13, metal grill 11 is located at the display In area 12.

Compared with prior art, the display device of the present embodiment, eliminates screen layer, replaces original with metal grill 11 Black matrix".Because the purpose for setting black matrix" is shading, opaque metal grill 11 can also reach the purpose of shading.Together When metal grill 11 can also play a part of shielding external interference, therefore former screen layer can be cancelled, and Such a design reduces aobvious The thickness of showing device.

These are only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and Any modifications, equivalent substitutions and improvements made within principle etc., should be included in the scope of the protection.
