Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

Embodiment one:

Shown in figure 3 ~ 8, the utility model discloses a kind of wedge angle transition module, it comprises module drain pan 1, LED pcb board 2, arc face shield 3, wherein:

Module drain pan 1, it is configured as xsect is class eccentric circular ring, and side is open end, and side is the housing of blind end; LED mounting points 11 is provided with in module drain pan 1.

Owing to considering the needs of the two flat-faced screen slitless connections intersected, LED point pel spacing should be consistent or be similar to consistent.That is, the spacing of the LED point pixel on LED pcb board 2 and side display screen consecutive point pixel, and LED pcb board 2 also should be identical with side display screen dot spacing or approximate identical from LED point pel spacing with it.

And how ensureing display screen slitless connection, module drain pan 1 is key component, its planform, and namely the angle of its sector structure must ensure that the display screen module of LED modular arrangements and both sides is consistent.

Shown in figure 9, by adjacent display screen appearance forrns, when two plane screens intersect, its crossing angle at 90 ° ~ 180 °, then:

A＝180-B (1)
