Description
Technical field
The utility model relates to large area without medium projection display technique field, and in particular to a kind of using laser projection
Without medium display device.
Background technique
Existing projection display technique is there are many projection pattern, and curtain/wall projections show, water curtain Projection Display, fog
Projection Display, fine gauze projection etc., these projection display techniques have the characteristics that one common needs to project medium.
Summary of the invention
The utility model provides a kind of display device, and the present apparatus is sent and closed using control visible light lasers, showing
The content shown, according to the image or text for wanting projection display contents, controls laser hair by way of visible laser pixel carrier wave
It penetrates in tower some or all of in visible laser, carries out in a certain order and time interval emits laser, pass through essence
Quasi-, quick, circulation control laser emits and closes laser, realizes and needs to show out in the aerial Projection Display of incorporeity medium
The image or text shown, the utility model are not necessarily to entity display medium, without any small media particle is sprayed in the sky, i.e.,
Projection Display can be realized in the sky.
For the utility model purpose of design more than realization, it is implemented with the following technical solutions:
1. the utility model provides a kind of display device, which includes:
One Laser emission tower and a laser absorption tower；
The Laser emission tower side by side, is fitly mounted with row's visible laser, laser injection side along tower body side
To unified in parallel towards Laser emission tower side exit wound of bullet；
The side of the laser absorption tower includes light absorbent, and laser absorption tower is placed in parallel with Laser emission tower, laser
Absorption tower includes the side of light absorbent in the Laser emission outlet side for facing Laser emission tower.
Further, described device further includes,
When whole visible lasers in the Laser emission tower work at the same time, the laser that Laser emission tower issues is formed
The visible laser light curtain of one planar；
The visible laser that the Laser emission tower is launched is irradiated to the light absorbent side of laser absorption tower, it is seen that light swashs
Light is absorbed and come out without extra laser reflection by light absorbent；
The visible laser light curtain forms a rectangle visible laser projection between Laser emission tower and laser absorption tower
Display area does not need laser absorption tower then when Laser emission tower carries out Projection Display against sky.
3. further, described device further include:
The visible laser, be it is a kind of transmitting laser wavelength range 400 ~ 700nm semiconductor laser.
Further, described device further include:
The visible laser can be a kind of monochromatic visible light laser, and it is sharp to be also possible to a kind of double-colored visible light
Light device can also be a kind of tri- color visible laser of RGB.
Further, utility model works principle is as follows:
Projection display contents (image or text) as needed carry out longitudinal Pixel-level segmentation to the display content, raw
At a kind of for controlling the binary message data of laser transmitting, in the binary message data of generation, in requisition for aobvious
Show that content is effective pixel points, setting binary message is 1, and no display content is inactive pixels point, and setting binary system is believed
Breath is 0；
Using the binary message data of the generation, laser is opened when according to effective pixel points being 1 and emits laser, nothing
Imitating pixel is 0, closes laser, synchronizes control to all visible lasers in Laser emission tower, is formed by column
A series of Pixel-level laser points issued, control laser accurate by picosecond (ps), quick, circulation emit and close sharp
Light is realized and goes out to need image or text to be shown in the aerial Projection Display of incorporeity display medium.
It, can also be according to effective picture when using the binary message data control laser transmitting of the generation and closing laser
Laser is closed when vegetarian refreshments is 1 and emits laser, and inactive pixels point is 0, and the mode for opening laser is controlled.
According to actual place demand, the placement distance between laser absorption tower and Laser emission tower is determined；
According to actual place demand, it is determined whether use the laser absorption tower.
The utility model has the beneficial effects that entity display medium is not necessarily to, without spraying any small medium in the sky
Grain, realizing that Projection Display goes out in the sky needs image or text to be shown.
Detailed description of the invention
Fig. 1 is specific embodiment of the present utility model schematic diagram；
Fig. 2 is the hardware system structure block diagram of specific embodiment of the present utility model；
Fig. 3 is the process flow of specific embodiment of the present utility model.
Specific embodiment
To be more clear the technical purpose, used technical solution and implementation result of the utility model, below with reference to
The utility model is described in further detail for attached drawing:
First, in accordance with, according to actual place demand, being determined between laser absorption tower S01 and Laser emission tower S02 shown in Fig. 1
Placement distance, laser absorption tower is placed in parallel with Laser emission tower, and laser absorption tower includes the side of light absorbent in face
The Laser emission outlet side of Laser emission tower；
Secondly, FPGA receives the image data for wanting Projection Display, binary format is carried out to image data, image data
It is converted into for while controlling the array data flow of laser works in S01 Laser emission tower；
Thirdly, FPGA is in the way of longitudinal parallel, each corresponding visible laser of pixel data, two into
The pattern matrix formula data flow of inhibition and generation is sent to the drive control device of visible laser, controls laser according to effective pixel points
Laser is opened when being 1 and emits laser, and inactive pixels point is 0, closes laser and does not emit laser.
