The advantages are, high luminance, high resolution ratio, large suitable environment range, simple structure and low cost.
Description
The present invention relates to a kind of laser visual development system, can be applicable on the displays such as TV, film, projecting apparatus.
Present visual development system (television set) comprise input circuit, high-frequency tuner, in put passage, sound channel, luminance channel, look treatment circuit, decoder matrix circuit, final stage video amplifier circuit, chromoscope, separated in synchronization, line-field sweep circuit and power circuit etc.External signal enters by input circuit, by high-frequency tuner, in put that passage amplifies, frequency-conversion processing is composite video signal, flow to sound channel, luminance channel, look treatment circuit, separated in synchronization and scanning circuit respectively.The sound channel output audio signal pronounces to loud speaker through power amplification again.Luminance channel and look treatment circuit export luminance signal respectively and the three primary colors signal of telecommunication is handled in decoder matrix circuit, and output red, green, blue three color difference signals are to final stage video amplifier circuit, and loading picture tube negative electrode.Separated in synchronization and line-field sweep circuit carry out calculation process with composite video signal and are loaded into respectively on row, the field deflection coil.There is the manufacturing process complexity in present visual development system, resolution is lower, brightness is low, colorimetric purity and problem such as poor for applicability.
The purpose of this invention is to provide that a kind of high-resolution, high brightness, high color purity and applicability are wide, the simple laser visual development system of technology.
The object of the present invention is achieved like this:
Laser visual development system comprise input circuit 1, high-frequency tuner 2, in put passage 3, sound channel 4, luminance channel 5, look treatment circuit 6, decoder matrix circuit 7, it is characterized in that: also comprise laser drive circuit 8, geometric drive circuit 9, color laser head 10, how much imaging systems 11, apart from control device 12 etc.; The input circuit input signal through high-frequency tuner 2, in put passage 3, look treatment circuit 6, decoder matrix circuit 7 and handle after, export four road signals of telecommunication, be respectively red, green, blue color difference signal and row field identification signal; Wherein decoder matrix circuit 7 is exported three color difference signals of first three road red, green, blue, flow to laser drive circuit 8, drive circuit is coupled the red, green, blue color difference signal and is loaded on the color laser head 10, color laser head 10 penetrates three kinds of different wavelength of laser of red, green, blue respectively, through penetrating a branch of nano level color laser after collimation, pressure beam, the neutralization; Inject imaging system 11 how much, there are horizontal deflection mirror, field deflection mirror in how much imaging systems 11, horizontal deflection penetrates laser head at next color laser level vibration deflection, be mapped to again on the field deflection mirror, color laser further in vertical oscillation deflection, is formed a width of cloth primary image, penetrate angle by adjusting laser apart from control device 12, change the image size, primary image is adjusted into the image of various sizes; The four road row field identification signal divides two-way again, and one the tunnel delivers to geometric drive circuit 9, control, the level of regulating horizontal deflection mirror, field deflection mirror shake sheet, vertical sheet, level and the VE sheet that shakes that shakes, and another road control is apart from control device 12, and control is moved apart from the lens of control device.
Benefit of the present invention is:
Brightness height, resolution height, the suitable environment scope is wide;
Construct small and exquisitely, structure is simple relatively, can make any form video product, as laser television machine, laser projection etc.;
Manufacturing process is simpler than present visual development system, so its cost is also relatively low;
Characteristic of laser is splendid, for holographic three-dimensional video picture is in the future laid a good foundation.
The present invention is described in more detail below in conjunction with drawings and Examples:
