Below in conjunction with the accompanying drawings and specific embodiment is described in detail to the present embodiment touch-control display module.

Fig. 1 is refer to, the present embodiment touch-control display module includes display module 10 and touch-control sensing layer 11.

The display module 10 can be Organic Light Emitting Diode (Organic Light-Emitting Diode, OLED) Display module, or thin film transistor (TFT) (Thin Film Transistor, TFT) display module, or can also be liquid crystal Show module (Liquid Crystal Display, LCD).

Fig. 2 is refer to, the touch-control sensing layer 11 includes：Basement membrane 110；Transparent conductive patterns 111, are formed at the basement membrane On 110；First insulating barrier 112, across the second electrode pattern 1111 between two first electrode patterns 1110；Metal Bridge 113, is formed on first insulating barrier 112, and described two first electrode patterns 1110 are electrically connected；Second insulation Layer 114, covers electrode pattern and the metal bridge 113.Wherein, transparent conductive patterns 111 include first electrode pattern 1110 With second electrode pattern 1111.

The first electrode pattern 1110 can be emitter stage pattern, and second electrode pattern 1111 is receiving pole pattern；Or Person's first electrode pattern 1110 is receiving pole pattern, and second electrode pattern 1111 is emitter stage pattern.

The touch-control sensing layer 11 uses metal bridging structure, it is possible to achieve the multiple point touching effect of high accurancy and precision, makes institute State the touching display screen that touch-control display module can be applied to high end performance.

The preparation method of the present embodiment touch-control sensing layer 11 specifically includes following steps：

S1：By exposure, development, etching and demoulding, transparent conductive patterns 111 are formed on basement membrane 110.What is formed is transparent Conductive pattern 111 is specially tin indium oxide (abbreviation ITO) pattern, and the basal lamina material can use polyethylene terephthalate Ester (Polyethylene terephthalate, PET) or COP optical materials, are flexible material, thinner thickness.

S2：The first insulating barrier 112 is made in transparent conductive patterns.First insulating barrier 112 is across positioned at two first electricity Second electrode pattern 1111 between pole figure case 1110, by the first insulating barrier 112 by adjacent first electrode pattern 1110 with Second electrode pattern 1111 is dielectrically separated from, and is that next step making metal bridge does insulation preparation.First insulating barrier 112 can be used Optical cement.

S3：Make metal bridge.Metal bridge 113 is formed on the first insulating barrier 112, by two electricity of first electrode pattern 1110 Connection.The metal bridge 113 can be using metal materials such as tin indium oxide, silver, MO.In addition, according to production technology ability, can control The width of metal bridge, can control metal bridge width in below 10um, make have concealment effect after being fabricated to finished product, not influence outward appearance Effect.

S4：The second insulating barrier is made, the second insulating barrier 114 covering electrode pattern and the metal bridge are used to protect away Line and metal bridge, it is to avoid oxidation, extend the service life of touch-control sensing layer, improve its reliability.Second insulating barrier 114 can Using optical cement.

Large stretch of touch-control sensing layer first can be produced using large stretch of basement membrane in actual production, be cut by laser after completing Segmentation method cuts to form simple grain touch-control sensing layer.Printed wiring board is connected on simple grain touch-control sensing layer, then by simple grain touch-control Sensing layer is fitted on display module surface；Or, also first simple grain touch-control sensing layer can be fitted in display module, then touching Printed wiring board is connected on control sensing layer.
