Please refer to Fig. 1, a kind of touching display screen 100, comprise be oppositely arranged the first substrate 110, second substrate 120, be placed in liquid crystal layer 130 between the first substrate 110 and the second substrate 120, be arranged at the first substrate 110 away from the first polaroid 140 of the second substrate 120 side and be arranged at second polaroid 160 of the second substrate 120 away from the first substrate 110 side.
First substrate 110 and the second substrate 120 are transparency carrier, as glass.The surface that second substrate 120 is relative with the first substrate 110 is provided with TFT electrode 122 and public electrode 124, for the Liquid Crystal Molecules Alignment state in co-controlling liquid crystal layer 130, thus to send light source and the light passing liquid crystal layer is modulated and shows image.Because TFT electrode 122 and public electrode 124 are all arranged on the upper surface of the second substrate 120, therefore the utility model touching display screen 100 is IPS (In-Plane Switching, plane conversion) touching display screen.First polaroid 140 and the second polaroid 160 all adopt machine flexible parent metal, are applicable to volume to volume technique, are applicable to produce in enormous quantities.Be appreciated that when using backlight as polarized light source, as OLED polarized light source, then without the need to the second polaroid 160.Second substrate 120 and the TFT electrode on it 122 form usually alleged tft array substrate with public electrode 124.
Please refer to Fig. 1, the side that the first substrate 110 is relative with the second substrate 120 is provided with filter layer 150 and transparency conducting layer 170, first substrate 110 forms usually alleged color membrane substrates with filter layer 150.Owing to being provided with the transparency conducting layer 170 providing touch controllable function, the color membrane substrates of the utility model touching display screen 100 is made to have touch controllable function concurrently.
In one embodiment, first form transparency conducting layer 170 at the first substrate 110 lower surface, then filter layer 150 is attached to the lower surface of transparency conducting layer 170.Be appreciated that and also first can form filter layer 150 at the first substrate 110 lower surface, then form transparency conducting layer 170 at the lower surface of filter layer 150.
Filter layer 150 comprises shading matrix and is scattered in the colored light-filtering units in shading matrix.Shading matrix is formed by black light-proofness material usually.Colored light-filtering units is formed by red, green or blue light resistance material, and the filter unit of three kinds of colors is uniformly distributed in shading matrix.The 26S Proteasome Structure and Function of filter layer can be identical with existing product, do not repeat them here.
Transparency conducting layer 170 is patterned and forms the first touch control electrode, for generation of the touching signals of first direction.Described public electrode 124 is double does the second touch control electrode, for generation of the touching signals of the second direction vertical with first direction.Therefore, the touching display screen 100 of this enforcement adopts double-deck touch-control sensing structure.
In one embodiment, the first touch control electrode formed by transparency conducting layer 170 patterning is extend along the Y direction of a rectangular coordinate system, and along the spaced strip electrode of X-direction.Public electrode 124 is somely to extend along X-direction, and along the spaced strip electrode of Y direction, one or more in public electrode 124 double as the second touch control electrode, form touch-control sensing structure with the first touch control electrode.Public electrode 124 can by the patterned acquisition of ito film layer.
When touching display screen 100 uses, the top of the first polaroid 140 also will be provided with protection panel.When finger touch protection panel; first, second touch control electrode will form touching signals due to capacitance variations; the touching signals formed by the first touch control electrode determines the coordinate figure of touch point in X-direction coordinate axis, determines the coordinate figure in the Y-direction coordinate axis of this touch point by the touching signals of the second touch control electrode.Like this, the position of touch point is just determined.
In touching display screen 100, original public electrode 124 is utilized to serve as the touch control electrode in a direction, the touch control electrode in another direction is set simultaneously on the first substrate 110, make touching display screen 100 realize touch controllable function but do not need to assemble a touch-screen in addition, reduce the thickness of touching display screen, be beneficial to and realize lightening, also greatly save material and assembly cost simultaneously.
