Abstract
The utility model discloses an LED (Light Emitting Diode) 3D (Three-Dimensional) display and a method. By adopting an LED display screen and a control system thereof, after one or more frames (pictures) of images are displayed, the control system quickly switches an LED lamp on the display screen, wherein the LED lamp refers to a medium capable of showing the image to human eyes on the LED display screen in general, so that the LED lamp sends a synchronous pulse signal (also called light signal) of a pair of glasses; during a process of opening 3D, the synchronous pulse signal is sent after one frame (picture) of image is displayed and the corresponding circulation is made on this, so that the related issues caused by additionally adding an emitter in a snapshot 3D synchronization method can be solved.
Description
Technical field
The invention belongs to LED 3D Display Technique field, particularly relate to the method for synchronization of display screen and glasses in 3 d mode.
Background technology
In recent years, along with market is to the hot broadcast of 3D image, thus create multiple 3D display mode, have shutter 3D display mode (being commonly called as active 3D), polarization type 3D display mode (being commonly called as passive type 3D), color 3D display mode etc.In shutter 3D display mode, LED display has multiple synchronization mode with between glasses, such as there are infrared synchronous mode, the 2.4G method of synchronization, Bluetooth Synchronous mode etc., these methods of synchronization have a common feature, be exactly that the extra reflector that increases of LED display needs is to follow glasses synchronous thus the effect of generation 3D, so some problems can be caused, the increase of such as cost, the putting of emitter position (if the position of reflector put bad just cannot be synchronous with glasses) etc.
Summary of the invention
The object of the invention is to solve in the method for synchronization of shutter 3D the relevant issues needing additionally to increase reflector and cause.
In order to solve in the method for synchronization of shutter 3D the extra relevant issues increasing reflector and cause, DST Link technology of the present invention utilizes the features such as the luminous far firing range of LED display, brightness are high, fast response time to solve this problem.
DST Link technology of the present invention comprises step and main points below:
LED display shown a frame (width) or multiframe (width) picture after control system can the LED (" LED " model refers to LED display can allow picture showing in the medium of human eye) on high-speed switch display screen make it to launch and the synchronization pulse of glasses (or claiming light signal).
The lock-out pulse launched has two kinds of modes: a kind of synchronization pulse being symmetric mode and launching, another kind is the synchronization pulse that asymmetric manner is launched.
The synchronization pulse that symmetric mode is launched has various modes: after often having shown a frame (width) picture, launch synchronization pulse and circulate with this, also can launch synchronization pulse after often having shown 2 frames (width) picture and circulate with this or launch synchronization pulse after often having shown 3 frames (width) picture and circulate with this, arrives by that analogy to launch synchronization pulse after often having shown n frame (width) picture and with this circulate (n is any numeral).
The synchronization pulse that asymmetric manner is launched has various modes: launch after having shown a frame (width) picture and launch lock-out pulse again after synchronous arteries and veins then shows complete 2 frames (width) picture and circulate with this, also can be launched after having shown a frame (width) picture launch lock-out pulse again after synchronous arteries and veins then shows complete 3 frames (width) picture and circulate with this, or launch after having shown 2 frames (width) picture and launch lock-out pulse again after synchronous arteries and veins then shows complete 3 frames (width) picture and circulate with this, arrive by that analogy to launch after having shown x frame (width) picture and launch lock-out pulse again after synchronous arteries and veins then shows complete y frame (width) picture and with this (x that circulates, y is any numeral).
No matter be that symmetric mode launches lock-out pulse or asymmetrical mode launches lock-out pulse, their necessity point & common ground must show rear transmitting synchronization pulse at certain frame (width) picture and do corresponding circulation with this in the process of opening 3D.
The synchronization pulse having shown rear transmitting at certain frame (width) picture can be the pulse only having a high level, such as: shown rear transmitting 1 lock-out pulse spike at certain frame (width) picture and circulated with this, or at certain frame (width) picture lock-out pulse that rear transmitting 1 high level is n microsecond has been shown and with this circulate (n is for Any Digit).
The lock-out pulse having shown rear transmitting at certain frame (width) picture can be the pulse period, if what launch is the pulse period, the high level width of the clock cycle of so launching, low level width, the number of pulse period can become, such as: shown 3 clock cycles of rear transmitting at certain frame (width) picture, the high level of first clock cycle is 20 microsecond low levels is 30 microseconds, the high level of second clock cycle is 10 microsecond low levels is 30 microseconds, the high level of the 3rd clock cycle is 15 microsecond low levels is 20 microseconds.By that analogy, n the clock cycle of rear transmitting has been shown at certain frame (width) picture, the high level of first clock cycle is a microsecond low level is b microsecond, the high level of second clock cycle is c microsecond low level is d microsecond, and the high level of the n-th clock cycle is x microsecond low level is y microsecond (n, a, b, c, d, x, y are any numeral).
In order to allow the switch of glasses left and right eyeglass with in the display left and right picture correspondence of LED screen, the synchronization pulse inserted between frame (width) and frame (width) can be asymmetric, such as: certain frame (width) picture has shown 3 clock cycles of rear transmitting, the high level of first clock cycle is 20 microsecond low levels is 30 microseconds, the high level of second clock cycle is 20 microsecond low levels is 30 microseconds, the high level of the 3rd clock cycle is 20 microsecond low levels is 30 microseconds, an other frame (width) picture has shown 3 clock cycles of rear transmitting, the high level of first clock cycle is 5 microsecond low levels is 10 microseconds, the high level of second clock cycle is 5 microsecond low levels is 10 microseconds, the high level of the 3rd clock cycle is 5 microsecond low levels is 10 microseconds, and circulate with this.Thus arrive by that analogy, n clock cycle is launched after having shown h frame (width) picture, the high level of first clock cycle is a microsecond low level is b microsecond, the high level of second clock cycle is c microsecond low level is d microsecond, the high level of the n-th clock cycle is e microsecond low level is f microsecond, m clock cycle is launched after having shown u frame (width) picture, the high level of first clock cycle is i microsecond low level is j microsecond, the high level of second clock cycle is k microsecond low level is g microsecond, the high level of m clock cycle is x microsecond low level is y microsecond, and with this (n that circulates, a, b, c, d, e, f, m, i, j, k, g, x, y, h, u is any numeral, and h is not equal to u).
