Abstract
A rotary display screen with LED bars is disclosed. The LED bars are sequentally arranged to surround a rotary axle linked with a control motor. After the motor is turned on, the axle rotates at required speed. The LED bars receive the image or text picture from the controller of display screen. Its advantages are less LEDs decreased by 90%, stable and clear display effect and low cost.
Description
From existing display screen control technology, the basic image of constant current, constant voltage drive circuit control display screen that adopts shows, with regard to the display screen body itself, majority is to be in a kind of " static " display mode, and the light-emitting diode of promptly forming the display screen body is not with the have living space change of position of institute's playing image, Word message.As want large tracts of land to show, and then space required and display area are equal to a large amount of light-emitting diodes formation, the especially full-colour display screens of size, and it involves great expense.The aspect, visual angle, the general visual angle of traditional display screen is less than 140 degree, and visual range is subjected to certain limitation.
For enlarging effective angular field of view, save the use amount of light-emitting diode, patent utilization human eye vision of the present invention persists this physilogical characteristics, with arrange in certain sequence, equally distributed LED bars links to each other with electric rotating machine by pivoted arm, rotating shaft, to the enabling signal of the electric rotating machine that preestablishes rotating speed with to the video playback signal of light-emitting diode, realize 360 a degree ring demonstration of no sight equation by displaying screen controller output.Can effectively reduce the use amount of light-emitting diode like this, save cost and enlarged angular field of view.
Patent of the present invention comprises screen body, electric rotating machine two parts.Now in conjunction with the accompanying drawings structural principle, the operation principle of each part described in detail one by one.
The display screen body is made up of some LED bars, the LED bars structure as shown in Figure 2, LED bars 1 is made of some independent displaying bodies 2, it is that display screen carries out the elementary cell that video shows, it is formed and performance has determined display screen display color effect, and its figure and literal show the influence that is not subjected to other independent displaying body.Can carry out local luminance, colourity adjusting to independent displaying body 2, can make the YC in each very little zone obtain independent adjustment, final brightness and the color of putting in order screen realized is consistent in error range; Each independent displaying body is again the minimum unit of maintenance of display screen simultaneously, when a certain regional LED bars occurs showing fault, can safeguard at this part.Independent displaying body 2 is classification with the color by light-emitting diodes red 3, green 4, blue 5 (or red, green dichromatisms), separately by row (along the independent displaying body vertically) be encapsulated on the bar template 6 of independent displaying body.
Electric rotating machine adopts servomotor, the compatible worker's electricity of the driving power of motor, civil power.Servomotor is owing to rotating speed, torque are subjected to the signal voltage control, so by the voltage sampling mode the very sensitive control signal of also following exactly of rotating speed of motor, torque is changed.The servomotor control principle as shown in Figure 3, input signal 1 is the voltage-type control signal, the amplification through signal amplifier 2 pairs of control signals outputs to AC servo motor 3, the control motor speed; Simultaneously, the voltage signal that AC servo motor 3 is exported is sampled, compare with the magnitude of voltage of input signal 1 through negative-feedback circuit 4, make the rotating speed of AC servo motor 3 accurately follow the variation of control signal by AC amplifier 2 adjustment in time to the control parameter value of AC servo motor 3.For the picture that LED bars rotation is play does not produce flickering, the rotating speed of electric rotating machine must reach human eye vision persist frequency 24 auspicious/second more than, the video image output of guaranteeing rotary screen continuously, stable.
Below in conjunction with Fig. 4 the display screen operation principle is discussed, carry out screen signal data acquisition and processing by control computer 1, vision signal is through displaying screen controller 2, handle by Control Software, produce digital screen signal, output to LED bars 3, displaying screen controller 2 produces the electric motor starting signal and is transferred to electric rotating machine 4, drive LED bars 3 to be higher than the speed rotation of 24 auspicious/seconds of human eye vision frequency by electric rotating machine 4, after determining the video refreshing frequency of being play, adjust the voltage-type control signal of motor, the rotating speed of constant electric rotating machine.LED bars 3 rotation the locus of process, pass through software by displaying screen controller, light successively and the corresponding redness of vision signal, green, blue light-emitting diode, utilize this physiological property of the persistence of vision of human eye, export parallax free image and show.
Patent of the present invention adopts " soft start " mode to display screen body power-supply system, and the electric current of large-size screen monitors is slowly promoted step by step, avoids the heavy current impact electric power system of bursting, and prolongs display screen useful life.
Claims (4)
1. the display screen body portion is made up of some LED bars, it is characterized in that LED bars evenly distributes on 360 scale faces of supporting wheel, consider working control to the electric rotating machine rotating speed, at least use 3 LED bars, on supporting wheel,, divide equally the card of 360 degree with the interval angle of 120 degree;
2. each LED bars is made of some independent displaying bodies, it is characterized in that each independent displaying body is made of some light-emitting diodes, light-emitting diode is a classification with red, green, blueness, separately by row (along the independent displaying body vertically) be encapsulated on the bar template of independent displaying body, the independent displaying body is the elementary cell that video shows, its image and literal show the influence that is not subjected to other independent displaying body;
3. there is relevance between demonstration of the video image of display screen and the control rotating speed of motor, it is characterized by, the enabling signal of motor is produced by displaying screen controller, that its rotating speed is higher than the human eye vision frequency is 24 auspicious/second, after determining the video refreshing frequency of being play, adjust the voltage-type control signal of motor, the rotating speed of constant electric rotating machine.The rotation of control driven by motor LED bars the locus of process, pass through software by displaying screen controller, light successively and the corresponding redness of vision signal, green, blue light-emitting diode, utilize the eye storage characteristic of human eye, export continuous, parallax free image demonstration;
4. display screen body power-supply system adopts " soft start " mode, it is characterized by the electric current that makes large-size screen monitors under software control and slowly promotes step by step, avoids the heavy current impact electric power system of bursting, and prolongs display screen useful life; Make the drive current of electric rotating machine promote step by step simultaneously, avoid of the impact of big electric current, prolong the useful life of electric rotating machine the electric rotating machine current circuit.
