During the four scanning displays, for providing multirow driving circuit close to pole pixel particle, make the compatible tradition of driving circuit
Driving.
The invention adopts the above technical scheme compared with prior art, has following technical effect that
1. panorama spherical surface pixel is divided with longitude and latitude and is arranged by the addressing display methods, the Zhou Changxiang of different longitude warps
Together, multiple and different rows are belonging respectively to close to the pixel of pole, frame buffer addressing will repeat pixel and copy to corresponding row address
In, compatible tradition display scanning sequence；
2. this method only operates the pixel arrangement of frame buffer, the row pixel data being misaligned is carried out at uniform alignment
Reason, the memory headroom that every a line is occupied all are aligned with maximum row, and empty pixel space, which is all provided with, is set to black.Although the method is internal
The use for depositing capacity becomes more, but is not required to carry out other operations, such as adjustment display timing, can be directly compatible with traditional
Show timing.
It, can be with 3. the addressing method is compared with traditional determinant addressing, two axis for using longitude and latitude to address as panorama
Panoramic picture is directly displayed on spherical surface display, therefore solves spherical panorama and shows because being sought caused by its curved-surface structure
Location difficult problem enables panorama spherical surface display to be detached from the dependence of processor, is directly decoded and is addressed by hardware circuit, drop
Low cost, improves efficiency, and unified panorama shows standard.

The light emitting source of the panorama spherical surface display；The luminescent material, spherical protective layer and spherical electric pole plate pass sequentially through physics
Depositional mode is attached on spherical circuit substrate.
The display direction of the panorama spherical surface display includes showing outside ball and showing into ball；The luminescent device
It is bonded by the point light source device shown suitable for spherical surface is densely arranged, such as LED patch.Narration in detail with reference to the accompanying drawing
Addressing display methods of the present invention.
Fig. 1 show scanning sequency coordinate schematic diagram.When observing spherical coordinate model, the earth's axis is enabled to be in vertical shape first
State, that is, warp direction is enabled to be in longitudinal, weft direction is in laterally.In scanning process of the present invention, first along warp
The scanning of line direction, that is, using warp direction as the line direction of display scanning sequence；Enter next line after a line end of scan,
At this moment select next line foundation be along weft direction, that is, allow weft direction as show scanning sequence column direction.?
During longitude, the longitudinal scanning across weft, the range of scan angle α is 0 degree and arrives 180 degree；Along longitude, across the transverse direction of line
In scanning process, the range of scan angle β is from 0 degree to 360 degree.
The coordinate system and scanning sequence of spherical scanning are defined, next it needs to be determined that the resolution of panorama spherical surface display
Rate.
Corresponding to different display material particle scales, by taking MiniLED as an example, the pel spacing of LED patch is d, if entirely
The radius of scape spherical surface display is r, then panorama resolution ratio is as follows:
In the case where panorama spherical surface display sizes determine, the resolution ratio of image has thus been determined.
On the other hand, this programme guarantees that image data is still complete two-dimensional matrix, therefore can be compatible with traditional figure
As addressing method.Since display addressing timing is along warp direction, near pole, multiple elements are stored in two-dimensional matrix
Be the same pixel in image value.
Because the pixel number of every a line be it is identical, meet traditional display addressing state, can be addressed from memory.According to
Traditional display addressing method, to resolution ratio xm*ymPicture frame be addressed, it is determined that pixel clock period can be obtained directly
To the frame per second of display.Image frame data needs to copy to a pixel in multirow, as shown in Figure 3.Consider Fig. 2 extreme case,
Only one pixel at leftmost pole, the element in the corresponding image data matrix of the pixel are located at all of matrix
Row, it would be desirable to the value of the pixel in image be copied in every a line of image data matrix, be copied into y from a pixelm
A value storage.It is fewer and fewer toward centre repetition from the two poles of the earth, without repetition at equator.Density sum number amount depends on the resolution of display
The density of light-emitting particles in rate and spherical surface.
The corresponding bottom circuit drives of the method for the invention are as shown in Figure 4.Close to the image pixel of pole, each pixel
The several elements that do not go together in correspondence image data matrix, pixel is all corresponding in every a line in image data matrix at pole
One element.These corresponding relationships can be connected with solid line, can also be not connected to, the pixel that leaves some space on Timing driver week
Phase.
The above is only some embodiments of the invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
