Abstract
The utility model provides a portable information terminal, comprising a body, a first cover body, a second cover body, alight source and a light source base. The first cover body comprises an optical amplifying element; the second cover body comprises a display device which comprises an LCD (Liquid Crystal Display, LCD) panel, a light guiding board and a reflect board. The light source is fixedly arranged on the light source base which can be inserted in the body. When working, the second cover body is positioned between the first cover body and the light source. The portable information terminal of the utility model utilizes self LCD panel fitted with the optical amplifying element and the light source to realize the projection function; the manufacturing cost of the portable information terminal with the projection function can be degraded, and the volume of the device can also be reduced.
Description
[technical field]
The utility model is about a kind of portable data assistance, refers in particular to a kind of portable data assistance with projecting function.
[background technology]
Because the development that ICT (information and communication technology) is advanced by leaps and bounds, the various deployments of broadband network are constantly quickened.People stride forward towards ubiquitous a networked society, realize a kind of time, site limitation of not being subjected to, and anyone can obtain the information communication environment of necessary information and knowledge whenever and wherever possible.At this moment, the information terminal as the interface of the direct exchange message of people is absolutely necessary.Mobile phone, PDA portable data assistances such as (Personal Digital Assistant, personal digital assistants) are subjected to extensive attention, and function also constantly strengthens.PDA, mobile phone etc. can be stored the data of relatively large amount, and have the function that surfs the web and consult Email.People are when portable data assistances such as use mobile phone, PDA, sometimes wish that more than one people can see the content that display screen is shown, at this moment just need portable data assistance to have information projection to big surface, so that the function that many people can easy-to-read.
Chinese patent has disclosed a kind of optical projection system No. 01125793.8, other device that this optical projection system is used for mobile phone, personal communicator, mobile computer, wearable computers, PDA(Personal Digital Assistant), desk phone and comprises the display screen of one.Projecting apparatus and this device itself become one or are integral with the charger or the support of this device, perhaps are inserted in this device by card slot.Many people watch for convenience, and this projecting apparatus has been expanded display capabilities with image projection by allowing the user on the surface of large-size, and this image also can similarly be presented on the display screen that is connected with this device.But the direct and above-mentioned information terminal device simple combination of projecting apparatus this device volume is increased, and be not easy to carry, and manufacturing cost is higher relatively.
[utility model content]
The utility model is to carry inconvenience and the too high deficiency of manufacturing cost in order to overcome existing information terminal with projecting function, a kind of portable data assistance with projecting function is provided, it utilizes the LCD display of self installing to realize projecting function, can reduce manufacturing cost and reduce volume.
The technical solution of the utility model is: portable data assistance of the present utility model comprises body, first lid, second lid, light source and light source base, first lid comprises the optics amplifier element, second lid comprises display unit, display unit comprises LCD (LiquidCrystal Display, LCDs) panel, light guide plate and reflecting plate, this light source is fixedly arranged on the described light source base, this light source base can be inserted body, during work, second lid is between first lid and this light source.
The beneficial effects of the utility model are: portable data assistance of the present utility model utilizes the LCD panel of self, cooperate light source and optics amplifier element can realize the function of projection, the manufacturing cost that can reduce the portable data assistance with projecting function also can reduce the volume of this device.

[embodiment]
Please in conjunction with consulting Fig. 1 and Fig. 2, portable data assistance of the present utility model comprises body 1, first lid 2, second lid 3, light source 4 and light source base 4a.Body 1 is rotationally connected by articulated structure 12 and articulated structure 13 and first lid 2 and second lid 3 respectively, and wherein articulated structure 12 and articulated structure 13 are can arbitrarily angled rotation and the articulated structure of location.
Body 1 comprises button (not indicating) and housing 1a, housing 1a bottom is provided with a chute 14, light source base 4a can slide in chute 14, when this portable data assistance is closed or when being used for general LCD and showing, light source base 4a can slide in chute 14 and insert among the housing 1a, when this portable data assistance was used for projection imaging, light source base 4a can skid off housing 1a in chute 14, and the light source 4 that is fixedly arranged on the light source base 4a provides light source for projection imaging.
Please in conjunction with consulting Fig. 1 and Fig. 3, when the utility model portable data assistance was used for direct viewing LCD, first lid 2 opened to maximum angle, be on the same straight line with body 1, second lid 3 opens to proper angle, watches LCD for the user, and light source 4 is concealed in second lid below.At this moment, the light guide plate 3b that has the side-light type light source can show LCD panel 3a for LCD panel 3a provides back light.
See also Fig. 1 and Fig. 4, when the utility model portable data assistance is used for projection, first lid 2 and second lid 3 open to suitable location, module backlight is turned over for 31 times, soon light guide plate 3b and reflecting plate 3c rotate around the axis simultaneously and open, pull out light source 4, second lid 3 is between first lid 2 bodies and light source 4, the position that cooperates optics amplifier element 2a and LCD panel 3a, adjust the position of light source 4, make it to realize the function of projection with LCD panel 3a combination, perhaps adjust first lid 2 simultaneously, the position of second lid 3 and light source 4 makes light source 4, LCD panel and optics amplifier element 2a can make up the realization projecting function, with the information projection on the LCD display to wall or on other larger sized surfaces, so that many people can watch simultaneously, expanded the display capabilities of this portable data assistance greatly.
Be appreciated that when the utility model portable data assistance is used for projecting function that because light guide plate 3a has translucidus, can only will turn under the reflecting plate 3c, light source 4 cooperates LCD panel 3a, light guide plate 3b and optics amplifier element 2a can realize the function of projection equally.
