Embodiment
See also Fig. 2 and Fig. 3, Figure 2 shows that decomposing schematic representation, Figure 3 shows that diagrammatic cross-section according to the touch control display device of first embodiment of the present invention according to the touch control display device of first embodiment of the present invention.In the present embodiment, touch control display device 10 of the present invention comprises liquid crystal display module 11, contact panel 12 and first framework 13.Liquid crystal display module 11 has first surface 111 and the second surface 112 that is oppositely arranged.Liquid crystal display module 11 comprises display panels and module backlight, and generally speaking display panels and module backlight fixedly form the liquid crystal display module by frame combination.Display panels closes on the first surface 111 of liquid crystal display module 11, and module backlight closes on the second surface 112 of liquid crystal display module 11.It should be noted that because display panels can't come display frame in luminous voluntarily mode, so adopt module backlight to provide display panels required light source.In addition, backlight module in fact also comprises assembly (not shown)s such as optical diaphragm group, light guide plate, light sources and reflector plate.Contact panel 12 is arranged at the first surface 111 of liquid crystal display module 11, uses contact panel 12 as input media, and the user can carry out every function of touch control display device by the display frame of directly touching touch control display device.First framework 13 comprises first flat board 131, at least one pair of sidewall and the block 136 that is extended to form along relative direction by the end of this at least one pair of sidewall.Be that to have two pairs of sidewalls that are oppositely arranged 132,133,134,135 with first framework 13 be example in the present embodiment, wherein sidewall 132 is oppositely arranged with sidewall 133, and sidewall 134 is oppositely arranged with sidewall 135.And sidewall 132,133,134,135, block 136 and first flat board 131 are formed in one.First flat board 131 covers the surface of contact panel 12 away from liquid crystal display module 11, and be oppositely arranged with block 136, block 136 is against on the second surface 112 of liquid crystal display module 11, makes liquid crystal display module 11 and contact panel 12 be coated in first framework 13.Thereby make first framework 13 both can prevent that contact panel 12 from directly exposing the purposes that reach protection contact panel 12, can play the fixedly purpose of liquid crystal display module 11 and contact panel 12 again, avoided the use of adhesive tape.Because in actual applications, the material of first framework 13, size and thickness all may exert an influence to the susceptibility of contact panel 12, so in general the choice criteria of the material of first framework 13 should be: 1. high strength; 2. scratch resistance; 3. high printing opacity; 4. high environmental suitability; 5. never degenerate and 6. low inductance, wherein the 6th the direct shadow of meeting is to arriving the panel performance.First framework 13 for example can be selected glass, polymethylmethacrylate (PMMA) or carbonic ester (PC) material for use, and the effect of glass is best, and PMMA takes second place, and PC is the poorest.For example with 3.2 cun contact panels, first framework 13 of glass material can be accepted the thickness of 0.5-0.8mm, and the PMMA material then can only be accepted the thickness of 0.5mm, and the PC material then should not surpass 0.3mm, otherwise can influence the susceptibility of contact panel.In the present embodiment, be that glass material is an example with first framework 13.
See also Fig. 4 and Fig. 5, Figure 4 shows that decomposing schematic representation, Figure 5 shows that diagrammatic cross-section according to the touch control display device of second embodiment of the present invention according to the touch control display device of second embodiment of the present invention.The present invention also provides another kind of touch control display device, and in the present embodiment, touch control display device 20 comprises liquid crystal display module 11, contact panel 12, second framework 14 and the 3rd framework 15.Liquid crystal display module 11 has first surface 111 and the second surface 112 that is oppositely arranged.Liquid crystal display module 11 comprises display panels, generally speaking display panels and module backlight fixedly form the liquid crystal display module by frame combination, display panels closes on the first surface 111 of liquid crystal display module 11, and module backlight closes on the second surface 112 of liquid crystal display module 11.Same, backlight module in fact also comprises assembly (not shown)s such as optical diaphragm group, light guide plate, light sources and reflector plate.Contact panel 12 is arranged at the first surface 111 of liquid crystal display module.Second framework 14 is used for ccontaining liquid crystal display module 11 and contact panel 12, the second frameworks 14 and comprises second dull and stereotyped 141 and the first side wall 142, and the outside of the first side wall 142 has at least one first fixture 143.And second flat board 141 cover the surface of contact panel 12 away from liquid crystal display module 11.The material of first framework 13 in the material of second framework 14 and first embodiment is identical, for example selects glass, polymethylmethacrylate (PMMA) or carbonic ester (PC) material for use, and the effect of same glass is best, and PMMA takes second place, and PC is the poorest.Be that glass material is an example with second framework 14 in the present embodiment.The first side wall 142 and second flat board 142 are formed in one.The 3rd framework 15 combines with second framework 14; the inboard of second sidewall 151 of the 3rd framework 15 has at least one second fixture 152; at least one second fixture 152 is corresponding also in conjunction with fixing second framework 14 and the 3rd framework 15 with at least one first fixture 143; make liquid crystal display module 11 and contact panel 12 combined second framework 14 and the 3rd frameworks 15 be coated on wherein; thereby make second framework 14 and the 3rd framework 15 directly expose the purpose that reaches protection contact panel 12 in conjunction with the fixing contact panel 12 that both can prevent; can play the fixedly purpose of liquid crystal display module 11 and contact panel 12 again, avoid the use of adhesive tape.Wherein, the 3rd framework 15 is a chase, claims backboard again.
In the present embodiment, at least one first fixture 143 of second framework 14 for example can be the engaging projection, and at least one second fixture 152 of the 3rd framework 15 for example is the engaging groove.But in contrast, at least one first fixture 143 of second framework 14 for example also can be the engaging groove, and at least one second fixture 152 of the 3rd framework 15 for example is the engaging projection.Perhaps, first fixture 143 and second fixture 152 are fixed orifice, wait by affixed means such as fixed screw or solids to lock, and fix second framework 14 and the 3rd framework 15 and form accommodation space and hold contact panel 12 and liquid crystal display module 11.
These two kinds of designs are owing to utilize first framework or second framework to fix touch control type LCD device with combining of chase (backboard), not only removed high transmission rate optics adhesive tape (or blooming), reduce production costs greatly, during as the need heavy industry, also only need simple steps just touch control type LCD device can be decomposed.
By the detailed description of above embodiment, be to wish to know more to describe feature of the present invention and spirit, and be not to come claim scope of the present invention is limited with above-mentioned disclosed embodiment.On the contrary, its objective is that hope can contain in being arranged in of various changes and the tool equality claim scope of the present invention.Therefore, claim scope of the present invention should be done the broadest explanation according to above-mentioned explanation, contains the arrangement of all possible change and tool equality to cause it.
