Edge be not always uniformly distributed, in order to make up the vacancy on area, often add pixel in some rows, this again cause
This line compared with other rows more crypto set some, cause segmentation portion image edge detailss deform.
Another scheme is that pentagon adds the football formula spherical screen that hexagon is put together, and a general spheroid is by 12
Pentagon and 26 hexagon splicing compositions.And each pentagon and hexagon be spliced by smaller triangle and
Into as described in patent CN201510060005, each pentagon or hexagon are by the different angle isosceles triangles of two kinds of specifications
It is put together.The spherical screen of this football formula also has the difficulty on realizing, because each small triangle can be regarded as one piece
Separate display screens, individually controlled by the driving of oneself, and rank scanning shows image, for the polygon of structural belt hypotenuse, two
Individual triangle can be spliced and combined, and their driving scanning is exactly reverse, be shown jointly to combine more triangle screens
Show that the image opened greatly has to decompose image information, polylith triangle screen coordinates rank scanning to control the image of various pieces to believe
Breath, this is in drive control, and software algorithm, which is realized, has great difficulty, and technical threshold is too high.
In fact, many plane special-shaped screens, are all by equilateral triangle, base angle as described in patent CN201210082470
Be 45 ° or base angle is that 67.5 ° of isosceles triangle is formed with various connecting methods, these abnormity screens when image information is presented,
Adjacent triangle is different because of scanning direction, picture is showed jointly, data transfer and type of drive are still a problem.
