The patterned transparent conductive layer 241 of touch-control sensing assembly 240 is directly to be formed on second substrate 230 through a sedimentation; Sedimentation comprises chemical vapour deposition technique (chemical vapor deposition; CVD) or physical vaporous deposition (physical vapor deposition, PVD).
In a preferred embodiment, be to use physical vaporous deposition (for example sputter (sputter)) that transparency conducting layer direct (directly) is deposited on second substrate 230, again through patterning process, form patterned transparent conductive layer 241.
In addition, please refer again to Fig. 1, in prior art, 40 groups of contact panel 20 and display panels fit together through adhesion layer 30, that is the substrate 41 of display panel 40 has certain thickness, and the combination of two panels needs the auxiliary of extra adhesion layer 30.
It is noted that with respect to prior art, the present invention directly is integrated in touch-control sensing assembly 240 on second substrate 230, not only can reduce the substrate thickness (like the substrate 41 of Fig. 1) of existing contact panel, and not need adhesion layer (like the adhesion layer 30 of Fig. 1).In addition; Because patterned transparent conductive layer of the present invention (for example, feeds alternating current (AC)) during as electrode, have self frequency and produce; This self frequency can not receive the influence of (being made up of first substrate 210, liquid crystal layer 220 and 230 of second substrates) of below display panels; Therefore, patterned transparent conductive layer 241 of the present invention not only can be used as electrode, also can play the part of the role of signal shielding layer (shielding layer) simultaneously.
In one embodiment of the invention; The processing procedure system of touch panel of the present invention can be prior to forming on second substrate 230 like Fig. 3 A or the described touch-control sensing assembly 240 of Fig. 3 B; Again with 230 upsets (flip) of second substrate; Form black matrix" (BM) and colored filter more in regular turn, again second substrate 230 and first substrate 210 are oppositely arranged and assemble afterwards, liquid crystal layer 220 is inserted between first substrate 210 and second substrate 230.In this embodiment, can be after assembling second substrate 230 and first substrate 210, that is do not insert before the liquid crystal layer 220, first substrate 210 is carried out the thinning step, to obtain the first substrate 210a of thinning.Can utilize existing lithographic process (photolithography) in the above-mentioned fabrication steps, this is also known by this area personage, repeats no more at this.In another embodiment of the present invention; After also can second substrate 230 and first substrate 210 being oppositely arranged earlier and assembling; Carry out the thinning step of one-sided substrate or bilateral substrate; After obtaining the first substrate 210a and the second substrate 230a of thinning by this, on the second substrate 230a of thinning, directly form touch-control sensing assembly 240 again.It is noted that, in the processing procedure process of touch panel, can carry out the thinning step to first substrate 210 or second substrate 230, with the first substrate 210a that obtains thinning or the second substrate 230a (seeing also Fig. 2 B-2D) of thinning according to the needs of practical application.
Touch control display panel 200 of the present invention can be proceeded successive process, for example comprises forming a polaroid (polarizer) on the touch-control sensing assembly, and forms a glass (cover glass), on polaroid.Also can be according to the demand of actual processing procedure, form other assembly on touch control display panel 200 or following.
The present invention directly is integrated in touch-control sensing assembly 240 on second substrate 230; This design also can be described as (on-cell) touch panel on the display module; When operation; The user can touch in the outer surface of touch-control sensing assembly 240 through finger or mode such as pointer, patterned transparent conductive layer 241 is responded to and is caused changes in capacitance, to produce sensing signal.The sensing signal that is produced can be sent to signal processing circuit, and then orients the position of touching the place.
It is noted that; The touch control display panel system of prior art separates making with contact panel and display panel, contact panel and display panel is fitted together again, and needs between the two panels to bind through adhesion layer (for example double faced adhesive tape or glue); Yet; When light (like adhesion layer or touch-control and the glass baseplate of plate) when the different medium, can produce partial reflection, and cause the black box reflectivity to rise.
Compared to prior art; Touch-control sensing assembly 240 of the present invention (in patterned transparent conductive layer 241 is arranged) is directly to be formed on second substrate 230, therefore, can reduce the reflectivity of touch control display panel; Improve penetrance, to promote the optics display quality of touch control display panel.
In sum; Touch control display panel of the present invention is not owing to need the extra substrate (for example glass) that contact panel is set; Therefore, the thickness and the weight of whole touch control display panel are minimized, and the thickness of thin film transistor base plate or colored optical filtering substrates is reduced to is less than or equal to 0.3 millimeter (mm); To reach frivolous purpose, also can reduce the process complexity and reduction processing procedure cost of contact panel in addition.
Touch control display panel of the present invention can be applicable to LCD (liquid crystal display; LCD); For example plane switching liquid crystal display (in-plane switching, IPS LCD) or fringe field switch LCD (fringe field switching, FFS LCD).
