The utility model is described in detail with reference to the accompanying drawings and examples, the examples of the embodiments are in attached drawing In show, in which the same or similar labels are throughly indicated same or similar elements or with the same or similar functions Element.The embodiments described below with reference to the accompanying drawings are exemplary, it is intended to for explaining the utility model, and cannot understand For limitations of the present invention.

In the description of the present invention, it should be understood that term " length ", " width ", "upper", "lower", " preceding ", The orientation or positional relationship of the instructions such as " rear ", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" be based on Orientation or positional relationship shown in the drawings, is merely for convenience of describing the present invention and simplifying the description, rather than instruction or dark Show that signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as pair The limitation of the utility model.

In the present invention unless specifically defined or limited otherwise, term " installation ", " connected ", " connection ", " Gu Calmly ", the terms such as " setting " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integral； It can be mechanical connection, be also possible to be electrically connected；It can be directly connected, can also may be used also indirectly connected through an intermediary To be the interaction relationship of connection or two elements inside two elements.For the ordinary skill in the art, The concrete meaning of above-mentioned term in the present invention can be understood as the case may be.

As shown in Figure 1-Figure 3, the utility model embodiment provides a kind of touch controlled type liquid crystal display die set, for mobile phone, The electronic equipments such as IPAD, notebook, the touch controlled type liquid crystal display die set include the touch-control lid of the setting of stacking fitting from top to bottom Plate 100, liquid crystal display 200 and backlight 300 wherein pass through OCA optics between touch cover 100 and liquid crystal display 200 Glue 400 is adhesively fixed.The touch cover 100 is that touch screen is integrated with cover sheet, and one side is played to liquid crystal The protective effect of display screen 200, on the one hand makes display module have touch function, and backlight 300 is used to mention for liquid crystal display 200 For backlight light, liquid crystal display 200 is enable to show required pattern when needing to show.

In the utility model, the liquid crystal display 200 includes the lower sheet glass 210 and upper sheet glass of opposite fitting setting 220.The relatively upper sheet glass 220 in the side of the lower sheet glass 210 extends outward an extension 211, the extension 211 Upper surface binding has driving IC500 and flexible circuit board 600, the bent master extended to display module of flexible circuit board 600 Plate connection, for realizing crystal display.

Since driving IC500 and flexible circuit board 600 only take up the partial region of extension 211, lower sheet glass 210 is prominent Extension 211 it is very fragile in the region of not set driving IC500 and flexible circuit board 600, the especially side of extension 211 Angle Position easily causes the fragmentation of extension 211 when display module is fallen and causes display abnormal, therefore the utility model It proposes that resilient mat layer is arranged in the upper surface of the extension 211, which avoids driving IC500 and soft route Plate 600 be arranged and extend to 400 abutting contact of OCA optical cement, in this way, when display module receives and falls or collide, by In the protective effect of resilient mat layer, so that the corner location of extension 211 is not damaged.

It should be understood that the resilient mat layer can be the upper surface for being separately locally provided at extension 211, such as As shown in Fig. 2, the resilient mat layer is two, it is respectively formed at the two sides of driving IC500, and the outside of resilient mat layer Side at least flushes setting with the outer side edges of extension 211；The resilient mat layer is also possible to be integrally disposed upon extension 211 Upper surface, such as shown in figure 3, avoid driving IC500 position be provided with integrated resilient mat layer, the resilient mat layer The positions of the outer side edges outer side edges that correspond to extension 211 also at least flush setting.The OCA optical cement 400 of the utility model It needs accordingly to extend, the OCA optical cement 400 can be the position phase with resilient mat layer in the position of corresponding extension 211 It is corresponding, and driving IC500 setting should be avoided.

The material of the resilient mat layer can be PET or foam as a further improvement of the utility model,.

In the utility model, the outer side edges of the resilient mat layer at least flush setting with the outer side edges of extension 211, more Excellently, the resilient mat layer can also bend the side or lower surface for extending to extension 211 from outer side edges, further increase anti- Damage effect.More preferably, the thickness of the resilient mat layer of the side and lower surface of the extension 211 is intended to lower than extension The thickness of the resilient mat layer of 211 upper surface, the selection of actual (real) thickness is depending on product real space demand.

The substrate of the touch cover 100 is glass, the OCA optical cement as a further improvement of the utility model, The difference of the refractive index of the substrate of 400 refractive index and touch cover 100 is in the range of 0-0.01.By in touch cover The OCA optical cement 400 of the substrate refractive index close of refractive index and touch cover 100 is set between 100 and liquid crystal display 200, Two reflectings surface are eliminated, to reduce the brightness of reflected light, greatly strengthen the readability of touch controlled type liquid crystal display die set；By In without enhancing backlight, thus avoid the extra power consumption as brought by enhancing backlight.

The liquid crystal display 200 further includes being arranged on upper sheet glass 220 as a further improvement of the utility model, The upper polaroid 230 on surface and the down polaroid 240 that lower 210 lower surface of sheet glass is arranged in, the OCA optical cement 400 connect Touch cover 100 and liquid crystal display 200, actually by the upper polaroid 230 of touch cover 100 and liquid crystal display 200 It is adhesively fixed by OCA optical cement 400.

The upper surface of the touch cover 100 is additionally provided with AR antireflective film as a further improvement of the utility model, the AR The setting of antireflective film substantially increases touch liquid crystal and shows so that entire display module only has 0.4% to the reflectivity of exterior light Readability of the mould group under strong light.

The touch cover 100 is polaroid resistor type touch panel as a further improvement of the utility model,.

The refractive index of the OCA optical cement 400 is 1.49 as a further improvement of the utility model, touch cover 100 The material of substrate be glass, the refractive index of glass is that the refractive index of 1.49, OCA optical cement 400 is identical as the refractive index of glass, The brightness of reflected light is further reduced, the readability of liquid crystal display die set is improved.

In the utility model, the driving IC500 and the separately binding setting of flexible circuit board 600.

Elasticity is arranged by the gap between the extension 211 and touch cover 100 of lower sheet glass 210 in the utility model Laying, resilient mat layer can provide cushion effect to the extension 211 of lower sheet glass 210, the extension 211 effectively prevent to exist Damage when receiving collision or falling.

Finally, it should be noted that above embodiments be only to illustrate the technical solution of the embodiment of the present invention rather than to its into Row limitation, although the embodiment of the present invention is described in detail referring to preferred embodiment, those skilled in the art It should be understood that the technical solution of the embodiment of the present invention can be still modified or replaced equivalently, and these are modified or wait The range of modified technical solution disengaging technical solution of the embodiment of the present invention cannot also be made with replacement.
