Abstract

The utility model discloses displaying and projecting equipment, which comprises a central processing unit, an interface circuit, a light emitting source, a liquid crystal displaying screen and a convex lens. The central processing unit is used for processing various functions of a telephone, and also used for processing, and displaying, is connected with the interface circuit and is connected to the liquid crystal displaying screen again. The light emitting source emits light ray which is projected on the screen through the contents of the liquid crystal displaying screen and the convex lens. The utility model has the advantages that the displayed contents of the telephone are magnified, the cost is low, and the visual area and the visual angle are enlarged.

Description

Display projector equipment

The utility model relates to a kind of telephone set projector equipment.

Today that communication is highly developed, phone enters in the common people family already, the particularly growth of how much levels of current traffic capacity and the reduction of telephone set price, telephone set enters in the common people family fast, along with the reduction of telecommunication fee and the release of the same price for urban and rural areas, will bring the spending spree of a new ripple in the rural area, the city is because the continuous release of new business, require to update, the update of telephone set has been quickened in the appearance of for example caller identification business.

And on the other hand, because the emerge in multitude of the new function of telephone set, as the Presentation Function phone of sending a telegram here, two-wire phone, multi-function telephones, except receiving calls, nearly all need Presentation Function now, and all be to adopt LCD (being LCD) to show now, LCD shows that the viewing area is little, and the visual angle is little, just can see shortcomings such as displaying contents near LCD (telephone set), and the cost of LCD becomes the secondary growth of power with the LCD size, also be subjected to the restriction of instrument size such as telephone set, caller identification box.

The purpose of this utility model is exactly to provide a kind of telephone set projector equipment in order to overcome the above problems, and is keeping cheaply increasing visual angle and viewing area under the prerequisite.

The utility model realizes that the scheme of above-mentioned purpose is: a kind of Display projector equipment is characterized in that: comprise CPU (central processing unit), light source, LCDs, convex lens; Described light source links to each other with CPU (central processing unit), by CPU (central processing unit) light source is controlled; Described LCDs is the transmissive liquid crystal display screen that negativity shows, the position that promptly needs to show is fully transparent, the position of not having demonstration then is opaque fully, LCDs is put between one times of focal length to two times focal length of described convex lens, the illumination of light source is mapped on the LCDs, and pattern shown on the LCDs is imaged on convex lens opposite side one plane by convex lens.

Adopt the beneficial effect of above scheme: in said apparatus, the CPU (central processing unit) one side drives the LCDs of the negativity demonstration of full impregnated, also control light source irradiation on the other hand on LCDs, and through content displayed on the LCDs, project on the convex lens, amplify and project on the barrier by convex lens focus, as wall, ceiling etc.Be scalable telephone set content displayed like this.Because projector equipment is not subjected to the restriction of LCD size, LCD can do very for a short time, thereby lower than general amplification mode cost, and has enlarged vision area and visual angle, almost can see content displayed in 180 degree visual angles and the bigger vision area.

Fig. 1 is the utility model synoptic diagram.

Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.

Embodiment one: see Fig. 1, shown in Display projector equipment comprise CPU (central processing unit) 1, light source (as one or more lamps, luminotron etc.) 2, LCDs 3, convex lens 4; Described light source 2 links to each other with CPU (central processing unit) 1, controls by 1 pair of light source 2 of CPU (central processing unit); Described LCDs 3 is transmissive liquid crystal display screens that negativity shows, the position that promptly needs to show is fully transparent, the position of not having demonstration then is opaque fully, LCDs is put between 4 one times of focal length to two times focal lengths of described convex lens, the illumination of light source 2 is mapped on the LCDs 3, and pattern shown on the LCDs 3 is imaged on convex lens 4 opposite sides one plane by convex lens 4.

In above-mentioned Display projector equipment, one the tunnel is that the LCDs that the negativity of full impregnated shows is driven by CPU (central processing unit) (promptly being commonly called as CPU) 1, the lamp 2 of another route CPU (central processing unit) 1 control shines LCDs 3, and through LCDs 3 content displayed, project convex lens 4, focus on by convex lens 4 and amplify and project on the barrier.

Above-mentioned Display projector equipment can extensively be installed on the telephone set, and makes on described CPU (central processing unit) 1 and the telephone set original CPU (central processing unit) shared.Central Processing Unit 1 also can link to each other with telephone key, is solidified with the various control signal in its internal storage, with the light (as the color of light, bright dark time etc.) of control content displayed, triggering mode and demonstration.

When outer signals (as ring, button etc.) triggers CPU (central processing unit) 1, it shows (place that is character display becomes transparent) with regard to driving LCDs 3 display screens, while CPU (central processing unit) 1 driven for emitting lights pipe 2 luminous shining on the LCDs 3, light sees through LCDs 3 transparent parts and projects on the convex lens 4, focus on and project on the barrier by convex lens 4, the distance of adjusting convex lens 4 and LCDs 3 is between one times to two times focal length of convex lens 4, and it is also clear that content displayed is amplified; Because CPU (central processing unit) 1 is just to have originally on the telephone set, can significantly reduce the size of the LCDs 3 on the conventional telephone set again, so can reach low-cost.Even can remove original LCDs, but effect is luxurious, style.

Above-mentioned Display projector equipment is except that can being installed on the telephone set, also can be installed on caller identification device (a kind of telephone set accessory, it can make the telephone set that does not have incoming call display function originally can possess incoming call display function) on, original CPU (central processing unit) is shared on described CPU (central processing unit) 1 and the caller identification device.Its effect that reaches be used for telephone set on be the same.

As seen, the utility model has made full use of the element on existing telephone machine, the caller identification device, on the basis that shows, content displayed is amplified and project on the barrier, on wall, in the almost 180 degree visual angles of barrier (as wall) and bigger vision area, can see content displayed like this.Projector equipment is not subjected to the restriction of LCDs size, and LCDs can be done very for a short time, can reduce cost, as long as the technology of LCDs does not limit; The distant place of the content of Projection Display in very wide scope can be seen, is not subjected to the angle limitations of LCDs, and is not subjected to the restriction of the content size of Projection Display, because the content size of Projection Display can be regulated.
