Description
Technical field
The present invention relates to technical field of touch-control display, more particularly to a kind of touch control display apparatus and preparation method thereof.
Background technology
The touch technology of existing touch control display apparatus mainly has external hanging type, single glass touch (One Glass
Solution, OGS), the technologies such as embedded (In cell) and externally embedded type (On cell).The touch control display apparatus of external hanging type due to
Touch screen is to be arranged independently of each other with display panel, and product thickness is larger, cannot meet some hand-held devices and portable device
Ultra-thin requirement, gradually eliminated.The touch control display apparatus of OGS is to combine pixel control layer and protective glass
Again on a display panel by optical cement fitting, have many advantages, such as that touch-control sensitivity is high, be current one of mainstream touch technology,
Primary disadvantage is that intensity is bad frangible.The touch control display apparatus of In Cell is that pixel control layer is integrated into display panel
On the inside of colored optical filtering substrates, but the touch control display apparatus of In Cell leads to its production yield because structure, processing procedure are more complicated
It is relatively low.The touch control display apparatus of On Cell be pixel control layer is arranged on the outside of the colored optical filtering substrates of display panel, and
One of current mainstream touch technology.

It includes array substrate 11 to control display device 10, colored optical filtering substrates 12 and be folded in array substrate 11 and colored optical filtering substrates 12 it
Between liquid crystal layer 14.Pixel control layer 13 is arranged on surface of the colored optical filtering substrates 12 far from 11 side of array substrate, including the
The one touch control electrode layer 13a and second touch control electrode layer 13b on the first touch control electrode layer 13a.Make the first touch control electrode
It is required to coating operation when layer 13a and second touch control electrode layer 13b, plated film material therefor is usually tin indium oxide at present
Transparent conductive materials such as (Indium Tin Oxides, ITO) need etch cleaning to form first and touch after having plated the first tunic
Electrode layer 13a is controlled, plates the second tunic in the first membrane surface again after the completion of cleaning, and cleaning is etched with shape to the second tunic
At second touch control electrode layer 13b, and need at least 4 illumination, cost higher in the process；If it is multilayer touch-control sensing
Layer 13 then needs to carry out multiple plated film.And above-mentioned touch control display apparatus needs to be etched cleaning to superimposed two membranes,
The risk of 13 rupture of line of pixel control layer can so be increased, therefore yield is very low.If one layer of 13 cabling of pixel control layer is disconnected
It splits, it is bad that it will cause whole display devices.In addition if etch cleaning totally can also not influence touch-control sensing function, same meeting
Keep product bad, to cause cost to increase.
