Figure 1A is the diagrammatic cross-section of a kind of touch control display apparatus of the utility model the first embodiment.Please refer to Figure 1A, touch-control display panel 1 comprises a demonstration module 11, a polaroid 12, one first patterned electrode layer 13 and one first transparent bonding layer 14.Touch control display apparatus 1 can be such as but not limited to being applied in a touch-control system, an interactive advertisement system, a preferential order system in sales field, a gate identification system, an information inquiry system, a drawing system or a portable mobile device etc.
In the present embodiment, show that module 11 is for liquid crystal display module (Liquid Crystal Display Module, LCM), it can comprise a substrate 111, a liquid crystal layer 112 and a membrane transistor (Thin Film Transistor, TFT) substrate 113.In this, substrate is preferably colorized optical filtering (Color Filter, CF) substrate.Substrate 111 is oppositely arranged with membrane transistor substrate 113, and liquid crystal layer 112 is arranged between substrate 111 and membrane transistor substrate 113.But, at other, implement in aspect, show that module 11 also can for example show module for light-emittingdiode shows module or organic light emitting diode (OLED), its inner structure can comprise respectively light-emittingdiode layer or organic light emitting diode layer with composition, with displacement liquid crystal layer 112.
Polaroid 12 is oppositely arranged with demonstration module 11.Furthermore, polaroid 12 is to be arranged at substrate 111 tops that show module 11, namely with respect to the opposite side of liquid crystal layer 112.In addition, polaroid 12 can comprise polyester film (PET film) or cellulose triacetate film (TAC film), and this is not restricted.In the present embodiment, polaroid 12 can be the cover sheet (Cover Glass) of touch control display apparatus 1, and its side away from substrate 111 can provide user directly to touch operation.In addition, also some functional layers, functional layers such as anti-dazzle, anti-fingerprint, antireflection can be set on polaroid 12.
The first patterned electrode layer 13 is arranged at polaroid 12 and shows between module 11.In the present embodiment, the first patterned electrode layer 13 is to be arranged on polaroid 12.Furthermore, the first patterned electrode layer 13 is to be arranged on polaroid 12 towards a side that shows module 11, the namely below of polaroid 12.Because the first patterned electrode layer 13 is to be formed on polaroid 12, polaroid 12 depends on or load-carrying unit as the first patterned electrode layer 13, can save the glass substrate that in prior art, patterned electrode layer depends on by this, to reduce the integral thickness of touch control display apparatus 1.On the implementation, the first patterned electrode layer 13 can form by manufacture crafts such as deposition, exposure, development or etchings.In addition, the first patterned electrode layer 13 can comprise single shaft to touch-control electrode (being for example comb electrode) or biax touch-control electrode (being for example two axial arrangements interlaced with each other), the present embodiment is to take two axial electrode as example, but not as limit.
