Abstract
The present invention discloses a touch screen liquid crystal display (LCD) panel. The touch screen LCD panel comprises a touch screen, an optical adhesive, a liquid crystal panel and a wire. The liquid crystal panel comprises a light emitting surface. The touch screen is adhered to the light emitting surface via the optical adhesive. The optical adhesive has transparent conductive particles disposed therein and is grounded via the wire. The present invention also discloses a touch screen mobile phone. The touch screen LCD panel provided by the present invention allows an external electric field to be shielded by grounding the optical adhesive with electrical conductivity, so that a manufacturing process of disposing a shielding layer in the liquid crystal panel is omitted, thereby reducing manufacturing costs.
Description
Technical field
The present invention relates to touch-screen field, particularly relate to a kind of touch-screen display panels and touch-screen mobile phone.
Background technology
In recent years, rapidly, especially touch-screen (TouchPanel) liquid crystal indicator has become the main flow of flat-panel monitor gradually in flat panel display development.Along with the optical characteristics required by liquid crystal indicator, the improving constantly of electrology characteristic, and consumer is to the demand of thinning display, design there is high-performance, low cost, ultra-thin touch-screen display panels become the main target of all big enterprises gradually.
The touch-screen of touch-screen display panels is positioned at directly over display panels, when staff goes to touch touch-screen, electrostatic can be produced or form external electrical field, thus the deflection of liquid crystal can be had influence on, to such an extent as to affect display effect, so need the CF surface in display panels to do one deck screen layer (as transparent conductive film layer, tin indium oxide) and it is connected with the GND of TFT substrate, so just, the effect of shielding external electric field can be played, but make this one deck screen layer and need increase by one making technology, add production cost.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of touch-screen display panels and touch-screen mobile phone, by the optical cement ground connection with electric conductivity being realized the shielding of external electric field, save and this making technology of screen layer is set in liquid crystal panel, reduce production cost.
To achieve these goals, embodiment of the present invention adopts following technical scheme:
On the one hand, a kind of touch-screen display panels is provided, comprise touch-screen, optical cement, liquid crystal panel and wire, described liquid crystal panel comprises an exiting surface, described touch-screen fits in described exiting surface by described optical cement, be provided with conductive, transparent particle in described optical cement, described optical cement is by described wired earth.
Preferably, described conductive, transparent particle is antimony tin oxide.
Preferably, described liquid crystal panel is provided with reference to earth point, and described optical cement is connected to described with reference to earth point.
Preferably, described liquid crystal panel also comprises the surface be oppositely arranged with described exiting surface, described liquid crystal panel has been cascading from described exiting surface to the surface that described exiting surface is oppositely arranged upper polaroid, CF substrate, liquid crystal layer, TFT substrate and lower polaroid, is describedly arranged in described TFT substrate with reference to earth point.
Preferably, described wire is silver slurry material.
On the other hand, also provide a kind of touch-screen mobile phone, comprise the touch-screen display panels described in above-mentioned any one.
Compared to prior art, the present invention has following beneficial effect:
Optical cement is made to have electric conductivity by arranging conductive, transparent particle in optical cement, optical cement is connected to the reference earth point of touch-screen display panels, optical cement current potential is made to be position at zero point, realize the effect of shielding external electric field, the screen layer be arranged in liquid crystal panel can be saved in prior art on the basis of display quality ensureing touch liquid crystal display device, thus eliminate one making technology, greatly reduce production cost.
Simultaneously due to without the need to additionally adding screen layer in liquid crystal panel structure, carry out assembling with touch-screen again after liquid crystal panel can be machined separately and form touch-screen display panels, decrease technology difficulty, improve the universal of liquid crystal panel, simplify the fabrication processing of touch-screen display panels.
Accompanying drawing explanation
In order to be illustrated more clearly in technical scheme of the present invention, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained as these accompanying drawings.
Fig. 1 is the section structure schematic diagram that the invention provides a kind of touch-screen display panels.
Wherein: 1 touch-screen; 2 optical cements; 3 liquid crystal panels; 4 wires; Polaroid on 31; 32CF substrate; 33 liquid crystal layers; 34TFT substrate and 35 times polaroids.
Embodiment
Below in conjunction with the accompanying drawing in embodiment of the present invention, the technical scheme in embodiment of the present invention is clearly and completely described.
Embodiments of the invention one provide a kind of touch-screen display panels, as shown in Figure 1, comprise touch-screen 1, optical cement 2, liquid crystal panel 3 and wire 4, liquid crystal panel 3 comprises an exiting surface, touch-screen 1 fits in the exiting surface of liquid crystal panel 3 by optical cement 2, being provided with conductive, transparent particle 21 in optical cement 2 makes optical cement 2 have electric conductivity, optical cement 2 is by wire 4 ground connection, optical cement 2 current potential is made to be position at zero point, realize the effect of shielding external electric field, the screen layer be arranged in liquid crystal panel 3 can be saved in prior art on the basis of display quality ensureing touch liquid crystal display device, thus eliminate one making technology, greatly reduce production cost.
Further, conductive, transparent particle 21 can be, but not limited to adopt ATO (AntimonyTinOxide, antimony tin oxide) nanometer ultramicron powder, there is good electric conductivity and transmitance, can combine with optical cement 2 in good condition, make optical cement have electric conductivity on the basis with stickiness simultaneously.
Further, liquid crystal panel 3 also comprises the surface be oppositely arranged with exiting surface, liquid crystal panel 3 stacks gradually the upper polaroid 31 of design from exiting surface to the surface be oppositely arranged with exiting surface, CF substrate 32, liquid crystal layer 33, TFT substrate 34 and lower polaroid 35, upper polaroid 31 and lower polaroid 35 are for polarisation of light, CF substrate 32 is that colored filter is for selecting the wave band glistening light of waves among a small circle for passing through and reflecting other wave bands not wishing to pass through, liquid crystal layer 33 is for applying liquid crystal deflection direction in electric field controls liquid crystal layer 33 thus changing polarisation of light direction, TFT substrate 34 is for array base palte is for applying pixel voltage thus changing display GTG.Understandable, because the liquid crystal panel 3 in the present embodiment without the need to additionally adding screen layer in panel construction, carry out assembling with touch-screen 1 again after liquid crystal panel 3 can be machined separately and form touch-screen display panels, decrease technology difficulty, improve the universal of liquid crystal panel 3, simplify the technological process of touch-screen display panels.
