Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Below in conjunction with specific embodiment, specific implementation of the present utility model is described in detail:
The utility model embodiment relates generally to the improvement of the structure to the touch control display apparatus based on Oncell technology, provides a kind of new button design scheme.With reference to figure 2, this touch control display apparatus mainly comprises the tft array substrate 1 and colored filter 2 that are superimposed, is provided with liquid crystal layer 3 between tft array substrate 1 and colored filter 2, and the surface of colored filter 2 tft array substrate 1 is dorsad provided with touch-control sensing layer 4.Identical with conventional touch device, drive liquid crystal layer 3 by tft array 11, to incident light carry out selectivity through and regulate transmitance, through light obtain Red Green Blue through colored filter 2, often organize the corresponding pixel of primaries.With the same side outstanding part of conventional touch device unlike, the relative tft array substrate 1 in one end of colored filter 2, namely extend the first protuberance 21, the upper surface of this first protuberance 21 or lower surface are provided with physical button pattern 5.Touch-control sensing layer 4 ends in physical button pattern 5 whereabouts, does not contact with it.
The present embodiment makes the same side of the relative tft array substrate 1 in one end of colored filter 2 protrude, this projection does not belong to viewing area, as Fig. 3, physical button pattern 5 is set at this first protuberance 21 and can not takies viewing area area, relative to traditional virtual key, improve utilance and the visual effect of display screen, relative to traditional physical button, more flexible to the design of complete machine structure, and be conducive to aesthetic appeal.
Further, this physical button pattern is preferably disposed on the upper surface of colored filter, is positioned at same aspect with touch-control sensing layer, and makes in the lump in same processing procedure with touch-control sensing layer.Concrete, touch-control sensing layer and physical button pattern can be made up through photoetching or Radium art of same electrode layer.
In the present embodiment, tft array substrate 1 extends the second protuberance 12 away from the same side of the relative colored filter 2 in one end of the first protuberance 21 of colored filter 2, it is superimposed that whole colored filter 2 and tft array substrate 1 seem dislocation, the upper surface of the second protuberance 12 of tft array substrate 1 is provided with TFT line bonding portion 13, for binding the conducting wire of tft array 11.Same, the upper surface of colored filter 2 near one end of the second protuberance 12 is provided with touch-control sensing circuit binding portion 41, for binding the conducting wire of touch-control sensing layer 4.
As another kind of execution mode, touch-control sensing circuit binding portion 41 can be set at the upper surface of the second protuberance 12 of tft array substrate 1, described touch-control sensing circuit binding portion 41 and TFT line bonding portion 13 is made to be positioned at same layer, and mutually insulated, colored filter 2 is provided with contact conductor near the side of the second protuberance 12, its one end connects touch-control sensing layer 4, contact conductor is along the side of touch-control sensing layer 4, stride across the side of colored filter 2 near the second protuberance 12, be connected to the touch-control sensing circuit binding portion 41 of the second protuberance 12 upper surface, this set-up mode contributes to reducing border width, improve screen accounting, again because described touch-control sensing circuit binding portion 41 and TFT line bonding portion 13 are all positioned at the same side of described tft array substrate 1, only can bind a flexible circuit board, to realize the signal transfer function of touch-control and display simultaneously, number and the area of flexible circuit board FPC therefore can be reduced.
With further reference to Fig. 2, this capacitive touch device also comprises the upper polaroid 6 be arranged on colored filter 2 and the lower polaroid 7 be arranged under tft array substrate 1, upper polaroid 6 and lower polaroid 7 are selected the polarization direction of the light of incident liquid crystal layer 3 and the transmitted light of liquid crystal layer 3 respectively, be appreciated that, liquid crystal layer 3 has two-layer alignment film and is clipped in the liquid crystal molecule in the middle of two alignment films, on this, the transmission direction of polaroid 6 is consistent with the orientation of the incident side alignment film of liquid crystal layer 3, the transmission direction of lower polaroid 7 is then consistent with the orientation of liquid crystal layer 3 transparent side alignment film.Upper polaroid 6, lower polaroid 7, tft array substrate 1 and touch-control sensing layer 4 are near one end of the first protuberance 21 alignment, and the region of upper polaroid 6 and lower polaroid 7 correspondence is viewing area.
With further reference to Fig. 2, be also provided with backlight module 8 in the incident side (namely in the incident side of lower polaroid 7) of tft array substrate 1.This backlight module 8 can be side entering type or down straight aphototropism mode set.The light source of side entrance back module is positioned at light guide plate side, and integral thickness is thinner, and optical uniformity is limited, the light source of down straight aphototropism mode set is positioned at immediately below optical element, integral thickness is slightly thicker than side entering type, but optical uniformity is better, can select the backlight module of suitable type according to actual needs.In addition, this backlight module 8 projection on colored filter 2 at least will cover colored filter 2, can provide backlight for physical button pattern 5 like this, such as user is presented in the void region of light therethrough physical button pattern 5, is particularly convenient to recognize key position at night.
With further reference to Fig. 2 and Fig. 3, can also arrange cover plate 9 on upper polaroid 6, all for below elements cover by cover plate 9, as the outer layer protection plate of contactor control device, usually adopt high transparency and have the glass plate of certain flexibility.The physical button pattern 5 being arranged at the first protuberance 21 of colored filter 2 can pass through cover plate 9 and presents, and button operation can be carried out in the relevant position that user touches cover plate 9.
The structure of the utility model to colored filter is improved, make it to extend a protuberance relative to tft array substrate, at protuberance, physical button pattern is set, viewing area area can not be taken, improve display screen accounting, and more flexible relative to the design of physical button, and complete machine structure more easily designs, outward appearance is create an aesthetic feeling more, is relatively applicable to the contactor control device based on Oncell technology.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
