Embodiment

Please with reference to Fig. 4; Display module 2 of the present invention is added 26 of elements and is formed by a display floater 20, one first housing 21, a framework 24, one second housing 22 and; Wherein, This framework 24 be located on display floater 20 around, in order to strengthening the structure of display module 2, but should be as limit; Preferred person, display floater 20 is a display panels, and the fluid,matching LCD panel is required, and display module 2 also comprises a light source module 25, between the display floater 20 and second housing 22, uses for showing in order to provide a light to pass display floater 20.

Then, first housing 21 and second housing 22 are bonded with each other, preferred person; First housing 21 and second housing 22 are chimeric each other with two frames; Make fixed display panel 20 and framework 24 among first housing 21 and second housing 22, wherein first housing 21 comprises a hollow area 210, and correspondence is arranged on the viewing area 200 of display floater 20; See through hollow area 210, the user can see the displaying contents (not shown) of the viewing area 200 of display floater 20; Needs (this display floater 20 can be penetration or double-sided display type display floater) according to the display floater that is cooperated 20; Second housing 22 also can comprise a hollow area (not shown); Correspondence is arranged at another viewing area (not shown) of display floater 20, makes the user can see the displaying contents (not shown) of this viewing area (not shown) of display floater 20.

Wherein, Display module 2 of the present invention also comprises one first attachment features 23, and it simultaneously is attached at the inboard of first housing 21, another side be attached at display floater 20 around; First attachment features 23 also comprises a ventilating structure 230; With so that the pressure in the hollow area 210 is able to average out, its pressure can be used with ambient pressure and regulate each other, avoids hollow area 210 because its pressure and ambient pressure generation pressure differential make and add element 26 and cave in; For further specifying the execution mode of ventilating structure 230, the present invention provides several embodiment to be described below.

Please be simultaneously with reference to Fig. 5 and Fig. 6, the overlooking and generalized section of those graphic ventilating structures for first embodiment of the invention; Ventilating structure 230 described in the present embodiment is a kerf 231; As shown in Figure 5; This otch 231 is till an inner side edge of first attachment features 23 extends to the 20a of edge above display floater 20, and this otch 231 makes first attachment features, 23 generation cracks, when first attachment features 23 is attached between first housing 21 and the display floater 20; This otch 231 still can make extraneous air communicate with hollow area 210, and the direction that its air is breathed freely is then shown in the curve arrow of Fig. 6.

The second embodiment of the present invention is please with reference to Fig. 7, and this is graphic to be the schematic top plan view of the ventilating structure of second embodiment of the invention; Ventilating structure 230 described in the present embodiment is an adhesive-free area 233; As shown in Figure 7; This adhesive-free area 233 is positioned on first attachment features 23 one side with respect to display floater 20; In the present embodiment, adhesive-free area 233 extends to the edge above display floater 20 from an inner side edge of first attachment features 23, does not exist owing to have colloid on the adhesive-free area 233; This adhesive-free area 233 make first attachment features 23 that a ventilation space is provided when being attached at display floater 20, so can make extraneous air communicate with hollow area 210.

Adhesive-free area 233 in the foregoing description can also be crossed over first attachment features 23 and be provided with, and is as shown in Figure 8, the air of hollow area 210 also can be used with ambient pressure regulate each other; Perhaps, this adhesive-free area 233 is arranged on first attachment features 23 the one side (not shown) with respect to first housing 21.

The third embodiment of the present invention is please with reference to Fig. 9, and this is graphic to be the schematic top plan view of the ventilating structure of third embodiment of the invention; Ventilating structure 230 described in the present embodiment is that an air-vent 232 runs through first attachment features 23 and an adhesive-free area 234; As shown in Figure 9; This air-vent 232 is positioned at the edge of display floater 20; Preferred person, this air-vent 232 is arranged between display floater 20 and the framework 24, because air-vent 232 makes first attachment features 23 produce pore; When first attachment features 23 was attached between first housing 21 and the display floater 20, outside air still can communicate with hollow area 210 with adhesive-free area 234 through air-vent 232.

The fourth embodiment of the present invention please be simultaneously with reference to Figure 10 and Figure 11; The element of present embodiment is not given unnecessary details at this with above-mentioned, and difference is that ventilating structure is present in one second attachment features 27; And second attachment features 27 be attached at first housing 21 with add element 26 around; Wherein ventilating structure is an adhesive-free area 233, and is shown in figure 10, and this adhesive-free area 233 is crossed over second attachment features 27; The direction that its air is breathed freely then shown in the arrow of Figure 11, can use equally with outside air and circulate by hollow area 210.

Please with reference to Figure 12; Display module 501 in the foregoing description can be applicable in the electronic installation 500; Its electronic installation 500 for example is a portable apparatus; For example be PDA, mobile computer (notebook computer), flat computer (tablet computer), portable computer (laptopcomputer), mobile phone, display screen device, LCD or non-portable desktop PC etc.; Wherein electronic installation 500 also comprises a controller 503, is electrically connected to display module 501, appears with the image of controlling display module 501.

In sum; In the embodiments of the invention, utilize attachment features to provide ventilating structure that the display floater place is used and form antivacuum state, to solve display floater and to add existing pressure differential between interelement hollow area pressure and the ambient pressure; To avoid adding the problem of element depression; And according to experimental result, the adhesive-free area among above-mentioned each embodiment can produce the effect of air communication, but because of bondline thickness very thin; Influence the problem of display floater so can avoid simultaneously in vacuum breaker or the pressure balance process foreign matter (like dust) to get into hollow area, thereby can reach basic dustproof effect.By this, technology of the present invention is not only for being applied to surely in the LCD panel module, and (for example organic LED display panel OLED) also can be used enforcement to the display floater of other type.

Though the present invention discloses as above with preferred embodiment; Yet it is not in order to limit the present invention; Those skilled in the art is not breaking away from the spirit and scope of the present invention, can do a little change and retouching, thus protection scope of the present invention should with accompanying Claim the person of being defined be as the criterion.
