Description
Technical field
The present invention relates to the simultaneous display technical field of LED display.
Background technology
Now, LED display is seen everywhere in daily life, and the application of large LED display screen is also got over
Come more.The display control of LED display has two kinds of systems, i.e. synchronization system and asynchronous system.Wherein, in asynchronous system, led
The asynchronous change of the display content of display screen and computer, after the content to be shown is editted on computers, is sent to control
In fabrication, control card is shown again, it is adaptable to the occasion not high to requirement of real-time；In synchronization system, led display screen phases
Shown when in the content Complete Synchronization on a big display, led display screens and computer display, it is adaptable to real-time
It is required that higher occasion, such as video display screen etc..Using synchronization system, LED display can be with simultaneous display computer
The image such as the video of designated area, animation in display, is more exposed to the welcome of people.Currently, the commonplace method of synchronization
Using the video card for supporting that double-screen synchronous is shown, to specify the image on interval real with one-to-one relation computer display
When on LED display show.
But, this conventional simultaneous display mode can by computer display yoke, particularly work as LED display
Effective display area（Dot matrix resolution ratio）When being mismatched with the resolution ratio of computer display, for example LED display is in transverse direction
When the dot matrix resolution ratio in direction is more than the resolution ratio of computer display, LED display is shown beyond partially due to not showing
Signal, will not show any content.At present, the resolution ratio of computer display is 2560*1600 to the maximum, if used commonly
The method of synchronization, the effective display area of LED display will be limited in the resolution ratio, and giant-screen is needed to use at some
In scene（Market, airport etc.）, it will it is restricted.As can be seen here, the limitation of the resolution ratio of computer display how is broken through,
LED display is set to obtain effectively showing to greatest extent, it is to avoid the situation that certain part of display screen is not shown occur, be current
It is badly in need of the technical problem solved in LED display simultaneous display technology.
The content of the invention
In view of there is above-mentioned technical problem in the prior art, LED is increased using computer program the invention provides one kind
The interval method of display screen simultaneous display, can be avoided the occurrence of because the dot matrix resolution ratio of LED display is more than computer display
The situation that the LED display that resolution ratio is caused can not be shown completely.
The method in the increase LED display simultaneous display interval that the present invention is provided, it is adaptable to effective display of LED display
Area is less than the situation of the resolution ratio of computer.
The method in the increase LED display simultaneous display interval that the present invention is provided, it is adaptable to the horizontal resolution of LED display
Rate is more than the lateral resolution of computer display, and longitudinal frame is less than or equal to 1/2nd feelings of computer longitudinal direction
Shape.Methods described is comprised the following steps that：
（1）Display screen body is segmented, its requirement is：LED display is divided into the first and second two parts, and LED shows
The Part I of display screen is located at the right side of LED display, and the Part II of LED display is located at the left side of LED display, often
The lateral resolution of the dot matrix of individual part is all not more than the lateral resolution of computer；
（2）Computer display is segmented, its requirement is, computer display separate upper and lower two it is non-overlapping
Region, the dot matrix resolution ratio phase of the resolution ratio in upper and lower two regions respectively with LED display Part I and Part II
Together；
（3）Respective coordinates are determined, according to step（2）The Part I and Part II and meter of the LED display of middle determination
The corresponding relation in upper and lower two regions of calculation machine display, determines that LED display Part I and Part II show with computer
Show the upper left corner in upper and lower two regions of device and the respective coordinates in the lower right corner；
（4）According to step（3）The respective coordinates of middle determination carry out wiring, described using a system control card during wiring
Be connected with second system control card on the signal branch plate of system control card, the scope that two system control card bands are carried respectively with
LED display Part I is consistent with the scope of Part II；
（5）The corresponding position relationship of two system control cards is converted into by lateral connection by computer program, shows LED
Display screen Part I and the image in upper and lower two regions of Part II simultaneous display computer display, its detailed process include：
For LED display to be divided into the step of two parts of Part I and Part II are respectively controlled,
For setting the Part I of the corresponding LED display of two system control cards and the resolution ratio of Part II and right
The step of answering coordinate,
For by the connection between the Part I and Part II of corresponding LED display 1 in two system control cards
The step of relation is converted to lateral connection,
For the image synchronization in upper and lower two regions of computer display to be included into the Part I in LED display
And the step of Part II.
Wherein, the Part I of LED display is located at the right side of LED display, and the Part II of LED display is located at
The left side of LED display.
From the foregoing, it will be observed that it is display that this method, which can be used for LED display to exceed in length in monitor resolution, height,
Situation within resolution ratio half.By computer program, make LED display simultaneous display beyond display part to calculating
Machine display is not used for the image in the region of display, so as to formally add the region of simultaneous display, has reached expansion
The interval length of LED simultaneous displays.It can be seen that, it can be avoided using this method because screen resolution is less than LED display resolution ratio
The LED display of appearance shows incomplete phenomenon.It is better especially in the application of some large LED display screens, it is more real
With.
