Embodiment
Existing conjunction with figs. illustrates preferred embodiment of the present invention.
See also Figure 1A and Figure 1B, it is respectively according to the solid of the display device of one embodiment of the invention combination synoptic diagram and according to the perspective exploded view of the display device of one embodiment of the invention.The display device of the embodiment of the invention (or the electronic installation with display device) 100 mainly includes a housing 110, a bracing frame 120, a light guide plate 130, a reflector plate 140, a light source 150, a display panel 160 and a leaded light component 170.
Shown in Figure 1B, Fig. 2 A and Fig. 2 B, wherein Fig. 2 A and Fig. 2 B are respectively according to the display device of one embodiment of the invention in the schematic top plan view under a kind of mode of operation and according to the schematic top plan view of display device under another kind of mode of operation of one embodiment of the invention.The housing 110 of the embodiment of the invention has an opening 111, the two relative first detent 112a and the two second relative detent 112b.At this, one first detent 112a and one second detent 112b form on the side of opening 111, and another first detent 112a and another second detent 112b form on another relative side of opening 111.
Shown in Figure 1B, bracing frame 120 is to be arranged among the housing 110.
As Figure 1B, Fig. 2 A, Fig. 2 B, Fig. 3 A, Fig. 3 B and shown in Figure 4, wherein Fig. 3 A, Fig. 3 B and Fig. 4 are respectively the diagrammatic cross-section of display device under a kind of mode of operation according to one embodiment of the invention, according to the display device of one embodiment of the invention under another kind of mode of operation diagrammatic cross-section and according to the three-dimensional diagrammatic cross-section of the leaded light component of the display device of one embodiment of the invention.The leaded light component 170 of the embodiment of the invention is to be arranged among the opening 111 of housing 110 in the mode that moves, and leaded light component 170 has one first transmittance section 171,172, two non-transmittance sections 173, one second transmittance section and two relative locating convex blocks 174.As Fig. 3 A, Fig. 3 B and shown in Figure 4, first transmittance section 171 is with respect to second transmittance section 172, and non-transmittance section 173 is between first transmittance section 171 and second transmittance section 172.Shown in Fig. 2 A and Fig. 2 B, locating convex block 174 is optionally to be sticked among the first detent 112a or the second detent 112b of housing 110.In addition, among present embodiment, the non-transmittance section 173 of leaded light component 170 is made by reflective material.More detailed, non-transmittance section 173 electrodepositables made by reflective material form on the outside surface of leaded light component 170.Therefore, the light that enters in the leaded light component 170 can be reflected by non-transmittance section 173, and can't penetrate to leaded light component 170 via non-transmittance section 173, thereby can promote the utilization factor of light.In addition, the inside of leaded light component 170 can be made by transparent materials such as glass or acryl.
Next the mode of operation of display device 100 is described.
At first, when display device 100 was in the bright environment (for example, outdoor location), leaded light component 170 can be moved into a primary importance, so that its second transmittance section 172 is connected in light guide plate 130, shown in Fig. 2 A and Fig. 3 A.At this moment, the locating convex block 174 of leaded light component 170 can be sticked among the first detent 112a of housing 110, to reach the purpose that leaded light component 170 is positioned primary importance.Then, the outer bright light of housing 110 can be in regular turn inputs among the light guide plate 130 via first transmittance section 171 of leaded light component 170 and second transmittance section 172.At this moment, the outer bright light of housing 110 can be accompanied by the light that light source 150 sent and penetrate to display device 100 via display panel 160 together.Therefore, display device 100 can allow a user see image shown on the display panel 160 clearly under the prerequisite of the luminosity that does not increase light source 150.
On the other hand, when display device 100 was in the darker environment, leaded light component 170 can be moved into a second place, so that its non-transmittance section 173 is connected in light guide plate 130, shown in Fig. 2 B and Fig. 3 B.At this moment, the locating convex block 174 of leaded light component 170 can be sticked among the second detent 112b of housing 110, to reach the purpose that leaded light component 170 is positioned the second place.As mentioned above, the outer light of housing 110 can can't input among the light guide plate 130 via leaded light component 170 because of stopping of non-transmittance section 173.Simultaneously, since non-transmittance section 173 stop that the light that light source 150 is sent also can not leak to outside the housing 110 via leaded light component 170.
In sum, because display device disclosed in this invention (or the electronic installation with display device) can be apt to add the effect of utilizing environment light source to reach to know show image,, and then can meet the demand of environmental protection and energy saving so it can save power consumption.Perhaps, with regard to another angle, because display device disclosed in this invention (or the electronic installation with display device) can make full use of environment light source and reach the effect of knowing show image, so it can reduce number of configured light sources, thereby can effectively reduce manufacturing cost and promote economic benefit.Wherein, above-mentioned electronic installation with display device can be one to have computing machine, PDA(Personal Digital Assistant) or the mobile phone of LCD or plasma display.
Though the present invention is disclosed in preferred embodiment; yet it is not in order to limit the present invention; any those skilled in the art; without departing from the spirit and scope of the present invention; should do a little change and retouching, so protection scope of the present invention is when looking being as the criterion that the appending claims scope defined.
