Embodiment
Below in conjunction with embodiment the present invention is elaborated.Please refer to Fig. 1, Fig. 1 is the structural representation of first embodiment of touch control LCD (Liquid Crystal Display) panel of the present invention.As shown in the figure, liquid crystal panel 100 has comprised first substrate 201, second substrate 301, a plurality of first sept 203 and a plurality of second sept 204.Wherein, second substrate 301 comprises the thin film transistor (TFT) array (not shown), and a plurality of thin film transistor (TFT)s 302 are positioned at the element region (not shown) of this thin film transistor (TFT) array; Chromatic filter layer, be positioned at the pixel region (not shown) of this thin film transistor (TFT) array, and cover part thin film transistor (TFT) 302, chromatic filter layer 303,304 shown in the figure is the chromatic filter layer of adjacent two kinds of different colours, for example 303 is green filter layer, 304 is blue color filter layer, but not as limit; Flatness layer 305 covers on the chromatic filter layer, plays protection and makes the effect that has an even surface; And pixel electrode layer 306, by nesa coating such as indium oxide (Indium Tin Oxides; ITO) form.In the present embodiment, 306 of this pixel electrode layers are distributed in pixel region.
According to present embodiment, be made in chromatic filter layer on the thin film transistor (TFT) array after, strengthened the aperture opening ratio of liquid crystal panel, simultaneously, as long as on another substrate, form two kinds of not septs of same-action, just can realize the touch controlled type display panels, saved the making flow process greatly.
What Fig. 2 showed is another embodiment of the invention.As shown in Figure 2, liquid crystal panel 110 forms one deck black-matrix layer 313 on the TFT of element region, in order to reduce the light leakage phenomena of pixel edge.Simultaneously, this black-matrix layer 313 is poor with the section of chromatic filter layer 314 formation that is positioned at pixel region, makes chromatic filter layer 314 be higher than black-matrix layer 313.And on first substrate, only need to form onesize first sept, 214, the second septs 213, and make first sept prop up higher chromatic filter layer 314, what then second sept was just natural forms spacing with second substrate, thereby realizes the effect of touch-control.It should be noted that, compare with enforcement 1, the making flow process of 2 pairs first substrates of this embodiment is easier, but on second substrate, need etch away the pixel electrode 316 that partly is positioned at pixel region, expose the flatness layer 315 that is positioned at this part, contact with the insulation of second substrate to satisfy first sept, second sept can be when pushing and the requirement of second substrate electric connection.
Fig. 3 is the third embodiment of the present invention.As shown in the figure, in touch control liquid crystal panel 120, with one independently insulation spacer 400 replace first sept among last two embodiment, only need to make flow process according to common liquid crystal, this sept 400 is spread between two substrates, and a common electrode layer 222 that needs to make second sept 224 and cover this second sept 224 gets final product on first substrate.It should be noted that this sept 400 necessary high and these second septs 224, to guarantee forming spacing between this second sept 224 and second substrate.
Fig. 4 is the 4th a kind of embodiment of the present invention.As shown in the figure, in liquid crystal panel 130, a plurality of first septs 337 are positioned on second substrate, and its other end props up first substrate, and a plurality of second sept 234 is positioned on first substrate, and are provided with reference to embodiment 1.Owing to two kinds of septs are made on the different substrates, therefore when making, have saved the technology difficulty of on same substrate, bringing because of two kinds of septs different in size.
Fig. 5 is the 5th a kind of embodiment of the present invention.As shown in the figure, in liquid crystal panel 140, a plurality of first septs 347 and a plurality of second sept 348 are positioned on second substrate simultaneously.First sept 347 is higher, and the one end props up on the public electrode 242 of first substrate, and with first substrate do the insulation contact; The skin of second sept 348 is covered by pixel electrode layer 346, itself and first substrate keep a spacing, when external force effect first substrate, second sept electrically contacts with the common electrode layer 242 of first substrate together with pixel electrode layer 346, to produce an activation signal, realize the function of touch-control.
Fig. 6 is another embodiment of the present invention.As shown in the figure, in liquid crystal panel 150,, more on the common electrode layer 252 of first substrate, made the figure 2522 of control circuit except with embodiment 4 has identical structure, this control circuit is in order to handling activation signal, and the control liquid crystal panel carries out video picture.After control circuit was produced on first substrate, second substrate only need design by common non-touch controlled type liquid crystal panel, has saved technological process and cost of manufacture greatly.Design though it should be noted that the structure of this embodiment reference example 4 herein, various embodiments provided by the invention can be realized present embodiment 6 described technique effects, not as limit.
By the above detailed description of preferred embodiments, hope can be known description feature of the present invention and spirit more, and is not to come claim scope of the present invention is limited with above-mentioned disclosed preferred embodiment.On the contrary, its objective is that hope can contain in the scope of claim of being arranged in of various changes and tool equality institute of the present invention desire application.
