Embodiment
Below with reference to accompanying drawing projection display equipment of the present invention and projecting method thereof are described in further detail.
Extremely shown in Figure 4 as Fig. 2, projection display equipment of the present invention comprises a transmitter 10 and a reverberator 14, wherein this transmitter 10 is made up of the light source 11 of integrated three lampets of red, green, blue and the convex lens 12, the concave mirror 13 that lay respectively at these light source 11 front and back, light source 11 is positioned at the focus place of convex lens 12, and rearmounted concave mirror 13 can guarantee that the beam energy major part of three-color light source 11 all launches.By the switch and the brightness of three lampets in the miniature control module control light source 11, under the coordination of miniature control module, transmitter 10 is capable of being combined launches various abundant colors according to the three primary colors principle.As shown in Figure 3, the beam reflection that the reverberator 14 of indication sends transmitter 10 among the present invention is to display screen 15, it is shaped as the regular hexagon prism, this reverberator 14 is not limited to the regular hexagon prism, also comprise equilateral triangle prism, square prismatic, Equal round polygons such as regular pentagon is prismatic, octagon prism, this shape is to select according to the information rate that will reflect.
As shown in Figure 4, projection display equipment of the present invention also comprises a decoding unit 17 and a miniature control module 18, between transmitter 10 and the reflector element (two reverberators 14 in three dimensions vertical mutually and forming a reflector element on the antarafacial) focuser 16 is set, the Electromechanical Control unit of miniature control module 18 can carry out closed-loop control to reverberator 14 (or reflector element), has the corresponding interface (as I2C, ISP etc.) and other external units or unit to carry out communication in the miniature control module 18; Transmitter 10 and focuser 16 are an assembled unit, and its effect is angle, a distance of adjusting the incidence reflection unit of light beam, also can finely tune the sharpness of Projection Display simultaneously.
The concrete implementing procedure of projecting method of the present invention is as follows:
(1) the external image video information inputs to decoding unit, this decoding unit carries out decoding processing to image or the video of being supported, convert relevant informations such as projection desired position, reflector element rotating speed, transmitter colour brightness to, it comprises the rotating speed separately of two orthogonal reverberators in the switch of three lamps in the desired transmitter and monochrome information, the reflector element;
(2) the microcontroller basis can be learnt the initial position of reflector element by interface, and makes its initialization, reverts to the default angle with transmitter unit;
(3) projection information of microcontroller self-demarking code in the future unit converts control action information to, by the interface with transmitter, reflector element both is synchronoused working;
When needs improved display area on the display screen curtain, miniature control module was by the frequency of operation of detecting transmitter and reflector element, and the control decoding unit increases more projected position information by its internal algorithm, to guarantee showing that profile is mellow and full; The user can manually finely tune the rotating speed of two reverberators in the reflector element by microcontroller according to the image that is projected on the display screen curtain, guarantees display effect; The user also can carry out adjustings such as brightness, color saturation by microcontroller to transmitter unit.
As shown in Figure 5, be in reflector element of the vertical composition of 90 degree with two reverberators among the present invention, purpose is: when two reverberators are rotated with certain rotating speed around its axle center respectively, by suitable configuration, the light that this combination can be penetrated a certain angle in space converts certain speed to and angle is carried out projection scanning to the display screen curtain.Is that example is introduced its principle of work and projecting method at this with two regular hexagon reverberators, this regular hexagon reverberator is a regular hexagon prism, wherein have one deck highly reflective energy element on the one side, this highly reflective can be mercury overlay film or mirror etc. by element.Scanning theory is as shown in Figure 6 in one direction for single reverberator: when reverberator 14 during with certain rotating speed rotation, in the swing circle of sixth, if reverberator 14 has turned over a degree (angle that state one and two liang of regular hexagons of state stagger among Fig. 4), can draw the function that b is a, S, N by geometric optical theory:
b＝F(a，S，N)
In the following formula: S---the space length of transmitter and reverberator; The space length of N---transmitter unit and display screen curtain.
Control in the transmitter unit in the tri coloured lantern information such as the switch of three red, green, blue lamps and brightness being combined into the color of required certain intensity of the moment by miniature control module, the signal reflex that the reflector element that two orthogonal reflector combination form transmitted transmitter in the different moment is to the diverse location in display screen zone.Because the human vision property effect, will see continuous pictures, the sharpness of Projection Display can by two reverberators in focuser and the control reflector element rotating speed separately adjust, the projected picture size can be adjusted by the position S that adjusts transmitter and reverberator.When needs improve image sharpness, miniature control module can be controlled decoding unit and provide more projected position and content information according to internal algorithm, guarantee promptly that when large screen display improves the frequency of operation of transmitter unit and reflector element effects such as sharpness that enough information guarantees to show, color saturation, brightness are arranged.
That more than introduces only is based on preferred embodiment of the present invention, can not limit scope of the present invention with this.Any the present invention is done replacement, the combination, discrete of step well know in the art, and the invention process step is done well know in the art being equal to change or replace and all do not exceed exposure of the present invention and protection domain.
