Abstract
The invention discloses a projector having functions of a short-focus projection television, and belongs to the technical field of projection. The projector comprises a machine shell, an optical engine, a mainboard system and a power supply, wherein the optical engine, the mainboard system and the power supply are arranged in the machine shell. The projector is characterized in that: the mainboard system comprises a mainboard, a driving panel, a fan/lighting control panel, a key panel, a remote control receiving panel, a tuner circuit and a power amplification panel, wherein the driving panel, the mainboard is connected with the driving panel, the fan/lighting control panel, the key panel, the remote control receiving panel, the tuner circuit and the power amplification panel; the power amplification panel is connected with a built-in loudspeaker; and the tuner circuit processes an input signal of the television, the mainboard receives and processes the video input signals and outputs the signals to the driving panel to control the work of the optical engine, the mainboard is controlled by operating the key panel or remote control receiving panel, and the driving panel controls the imaging of the optical engine, so that the signals are outputted to a projection lens and then projected onto a big screen or wall. The projector can directly access the television signals, and with the projector, the large-size television programs can be viewed at the shortest projection distance.
Description
Technical field
The invention belongs to the shadow casting technique field, be specifically related to a kind of projector with functions of short-focus projection television.
Background technology
Tradition projector comprises that projectiveness shows and reflectivity shows, generally comprise Circuits System, the coloured light synthesis system, optical imaging system and projection screen are after size is big, because resolution is low, the also big image quality that must cause of size is fuzzy, general home projector all is the part as home theater, and it is a cover system, environment, sound equipment, curtain, film source or the like all is the factor that must consider, indispensable, it moves the line of connecting with the mains home unlike TV, connects television signal line, that's all, therefore projector also will be equipped with processing television signals system and sound system separately, sees that TV programme is very inconvenient, and interface is also few.
Summary of the invention
For solve prior art above-mentioned defective, the object of the present invention is to provide a kind of directly incoming television signal, directly projects images is watched the projector with functions of short-focus projection television of large-sized TV programme to giant-screen or on the wall with the shortest projector distance.
For achieving the above object, the technical solution used in the present invention: this has the projector of functions of short-focus projection television, has casing, in casing, be provided with light engine, main board system and power supply, it is characterized in that: described main board system comprises mainboard, drive plate, fan/the control panel of lighting a lamp, keypad, the remote control dash receiver, high frequency tuner circuit, power board, mainboard and drive plate, fan/the control panel of lighting a lamp, keypad, the remote control dash receiver, high frequency tuner circuit, power board connects, power board connects built-in loudspeaker, high frequency tuner circuit is handled tv input signal, mainboard receives and handles each road video input signals, and output signal to drive plate, the work of control light engine, come control main board by operation push-button plate or remote control dash receiver, the imaging of drive plate control photo engine, thereby output signal is to projection lens, projects on the giant-screen or on the wall.
Adopt the beneficial effect of technique scheme: this has the projector of functions of short-focus projection television, has high frequency tuner circuit, high frequency tuner circuit is connected with mainboard, realize projection TV video reception and processing capacity, after carrying out the processing of encoding and decoding behind the high frequency tuner circuit received television signal that described TV signal receives, TV signal is input to the master chip of main board system, master chip carries out after video image finishes dealing with again, signal is input in the photo engine drive plate again, by the optical imagery display part image is shown, last image projection is to giant-screen or on the wall, thereby for the direct TV reception of people, and obtain large-size images with the projection of the shortest projection distance, the TV of watching for more people.The user only need connect the power supply line, after wireless remote control or the button start, connects antenna, selects channel, just can see large scale projection TV program.The projection television projecting machine is also built-in in addition loudspeaker, more convenient, need not external voice box, be the projection television projecting machine of a whole set of holonomic system.
