The touch polarization layer comprises a polarizer and a touch layer formed on the surface of the polarizer, and the touch polarization layer and the display module body are completely fit or a gap is formed between the touch polarization layer and the display module body. According to the touch display module, the touch layer is formed on the polarizer in a screen printing or plating and carving mode to form the touch polarization layer, the processing difficulty of light and thin touch display modules is reduced, the yield of the touch display modules is increased, and the production cost of the touch display modules is lowered.
Description
Technical field
The present invention relates to human-computer interaction device's touch-control display technique, be specifically related to touch-control and show module and use this touch-control to show the touch screen of module.
Background technology
Along with the development of touch-control display technique, touch screen (touch-control or touch display screen) is widely used in various electronic equipments, as smart mobile phone, panel computer, notebook computer, TV, the commercial unit etc. that comprises touching display screen.
Particularly, along with Mobile Communication Service industry and multimedia fast development, as portable terminals such as dull and stereotyped smart mobile phone, panel computers, waited until rapidly and popularized, lightening, cost degradation more and more becomes the target of each large mobile phone or the pursuit of the raw manufacturer of panel computer.
In order to reach lightening and cost degradation; all big enterprises have proposed OGS on the basis of traditional touch-control demonstration module G/G (two glass), G/F (glass adds ito thin film), and (touch control layer is engraved on cover glass cover plate and is reached integrated by plating; as Figure 1A), On-Cell (touch control layer is engraved on liquid crystal display by plating, as Figure 1B) and In-Cell (be arranged at liquid crystal display inside by touch-control circuit.As Fig. 1 C).In order to realize, show object in actual use, also can fit below the liquid crystal display of above-mentioned schematic diagram lower polaroid and/or the parts such as backlight.
But no matter be OGS, On-Cell, or In-Cell, under current process conditions, production yields is all lower.For OGS and On-Cell, be all to carve touch-control circuit in plating on glass, can cause strength of glass to weaken frangible; For On-Cell, more seriously can cause the destruction of liquid crystal display layer.These have all caused the increase of production cost, fail to realize the original intention of cost degradation.
Summary of the invention
Order of the present invention is to provide the structure that a kind of novel touch-control shows module, effectively reduces production costs reaching in lightening.
The object of the invention is to realize by following technological means:
Touch-control shows a module, comprises touch-control polarizing layer, shows module; Described touch-control polarizing layer comprises polaroid and is formed at the touch control layer on described polaroid surface, forms full laminating or gap between described touch-control polarizing layer and described demonstration module.
Sensor circuit in described touch control layer and driving circuit are arranged on the same surface of described polaroid.
The mode that described touch control layer is carved by silk-screen or plating is formed at the surface of described polaroid.
In described gap, be filled with gas, or be evacuated.
The thickness in described gap is less than or equal to 1mm.
Order of the present invention is to provide a kind of touch screen that uses above-mentioned novel touch-control to show module.
A touch screen, comprises that cover glass cover plate, the touch-control of arranging successively show module from top to bottom; Between the upper surface of described cover glass cover plate and described touch-control demonstration module, form gap.
In described gap, be filled with gas, or be evacuated.
The present invention is due to described touch control layer is formed at and has been formed touch-control polarizing layer on described polaroid by silk-screen or the plating mode such as quarter, reduced the difficulty of processing that lightening touch-control shows module, improve the yields of touch-control demonstration module, reduced the production cost of touch-control demonstration module.
In addition, touch screen provided by the invention, owing to forming the gap that is filled with air between described cover glass cover plate and the upper surface of described touch-control demonstration module; Do not need in process of production described cover plate and touch-control demonstration module to fit by optical cement, do not form a combination between the two; Production process and time cost have been reduced; In addition, in production and use procedure, once occur that cover plate just only need to be changed described cover plate by the situation of being fallen row or breaking, and has reduced maintenance cost.
