Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further described in detail.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Fig. 1 shows the system chart of the utility model home projector.Projector of the present utility model comprises multimedia decoding module 1, ray machine driver module 2 and the ray machine module 3 of in turn communication connection, also comprises being arranged in ray machine module projection lens 4, the radiating module 5 that adjacent ray machine module is connected with projection lens and detection and the adjusting module 6 that is connected with the ray machine module with the ray machine driver module afterwards.
Multimedia decoding module 1 is used for USB, the SD card, and AV IN (composite video), VGA IN, the signal of the interfaces such as HDMIIN input is decoded, and output LVDS signal is given to the ray machine driver module; Ray machine driver module 2 is linked up with ray machine module 3 according to the LVDS signal of input, the DMD(Digital Micromirror Device in the control ray machine module 3) 33 actions, the output display picture; Ray machine module 3 is camera lens modules of making according to TI DMD specification, and as shown in Figure 2, ray machine module 3 comprises led light source 31, light path system 32 and the Digital Micromirror Device 33 of arranging in turn.Led light source 31 comprises red-light LED array, green light LED array and blue-ray LED array; Light path system 32 comprises the first collimation lens, the second collimation lens and the 3rd collimation lens that is oppositely arranged respectively with red-light LED array, green light LED array and blue-ray LED array.
Ray machine driver module 2 comprises led light source driver element and Digital Micromirror Device driver element, can be respectively applied to driving LED light source and Digital Micromirror Device.Radiating module 5 comprises many heat pipes, a plurality of radiating fin and a small blast fan; Wherein the thermal source of many heat pipes and light path system, Digital Micromirror Device and projection lens is close to setting, and a plurality of radiating fins are around being arranged on around described many heat pipes, and the air supply direction of small blast fan is over against described a plurality of radiating fins.Detection and adjusting module 6 are used for automatically detecting white balance, color and the colour temperature of whole system when work of described home projector, and automatically adjust the state of the whole system of described home projector.Projection lens 4 is zooms, can be by the focusing ring on the rotating and projection machine so that the image focusing advises using still image to focus.
The utility model adopts the DLP technology, and DLP is the abbreviation of " Digital Light Procession ", is digital light and processes, and that is to say that this technology wants first signal of video signal through digital processing, and then light is projected.It is based on digital micromirror elements---DMD(Digital Micromirror Device) finish the technology that viewable numbers information shows.Saying specificly, is exactly that DLP shadow casting technique has used Digital Micromirror Device (DMD) and is used as main crucial treatment element to realize the digit optical processing procedure.Light source is incident upon on dmd chip by light path system, dmd chip after receiving the control signal of control panel with light emission to projection screen.The dmd chip outward appearance seems a just small pieces mirror, is encapsulated in the confined space of metal and glass composition, and in fact, this face mirror is comprised of hundreds thousand of and even up to a million micro mirrors.Take the dmd chip of XGA resolution as example, at wide 1cm, 1024 * 768=786432 micro mirror unit arranged in the area of long 1.4cm, each micro mirror represents a pixel, and image just is made of these pixels.
The DLP system of home projector of the present utility model can be divided into two classes.One class is monolithic DLP system, and in a single DMD optical projection system, DLP is operated in the sequential color pattern.Input signal is converted into the RGB data, and data write the SRAM of DMD in order, and the light that the red, green, blue led array sends is penetrated on DMD according to priority.When going up to be mapped to DMD when ruddiness, eyeglass tilts to " opening " according to position and the intensity that red information should show, green and blue light and vision signal also are work like this.Human vision system is concentrated red, green, blue information and is seen a full-color image.By projecting lens, the image that forms on the DMD surface can be projected on the giant-screen.Another kind of is three DLP systems, in this system, because led light source has adopted red-light LED array, blue-ray LED array and green light LED array, these three arrays comprise respectively a plurality of ruddiness, blue light and green light LED, this system uses three DMD, and a DMD is corresponding to a kind of primary colors.The main cause of using three DLP optical projection systems is in order to increase brightness.By three DMD, can directly project continuously on its DMD from the light of each primary colors.The more light of result arrives screen, provides a brighter projected image.
Projector of the present utility model has the multiple interfaces such as AV in interface, mini VGA interface, mini HDMI interface, USB interface, SD card interface, earphone interface and power interface, can support the composite video input of the products such as PC, set-top box, DVD, digital camera, iphone, ipad.This projector also comprises loudspeaker and is arranged on the lifting foot that is used for adjusting the projects images height of described projector bottom.In addition, this projector also has the infra-red remote control inductor, can accept the infrared control signal of telepilot, and the operations such as the start/shutdown of projector, skip forward/back, broadcast/time-out, volume are controlled.
Fig. 3 shows the system architecture brief introduction synoptic diagram of home projector of the present utility model.This system architecture at first comprises start logo, comprises that then USB flash disk, SD card, input source and system arrange this several bulks.USB flash disk and SD card include video, photo and text, and wherein video comprises video file List and video player, and photo comprises picture file List and picture playing device, and text comprises text List and text player; Input source comprises AV input, HDMI input and VGA input; System's setting comprises these several of image, sound, time and settings.
What Fig. 4 showed home projector of the present utility model arranges the options menu synoptic diagram.This arranges options menu and comprises these several parts of image, sound, time and setting.Image part divides and comprises that image model, colour temperature, highlighted pattern, keystone, projection pattern, zoom mode and computer arrange the selection of these aspects; Sound partly comprises the selection of acoustic pattern, balance, automatic volume and these several aspects of surround sound; Time portion comprise the time (day. month. year with in time. minute), unused time, unused time and dormancy selection regularly; Setting section comprises that menu language, answer factory arrange, menu is hidden automatically and the selection of software version.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, all any modifications of making within spirit of the present utility model and principle, is equal to and replaces and improvement etc., all should be included in the protection domain of the present utility model.
