2464 can be inline.Certain third sub-light source 2462 and the 4th sub-light source 2464 can not also be located along the same line.
The second gap is provided between third sub-light source 2462 and the 4th sub-light source 2464.It should be noted that adjacent two
The size in the second gap between a third sub-light source 2462 and the 4th sub-light source 2464 can be equal, can also be unequal.It can
With understanding, the second gap between third sub-light source 2462 and the 4th sub-light source 2464 it is equal sized when, it is two neighboring
Second light source equidistant arrangement.First light source 244 can spatially form the first projection such as first and project 224', the first projection
224' may include the first Projection Division 224'a and the second Projection Division 224'b, the first Projection Division 224'a and the second Projection Division 224'b
The distance between first light source 244 can be indicated in the size of 242 width direction of frame.First Projection Division 224'a and third
The distance between light source 2462 is equal to the second Projection Division 224'b and the 4th sub-light source 2464.It is understood that the first Projection Division
The distance between 224'a and third sub-light source 2462 are equal to the second Projection Division 224'b and the 4th sub-light source 2464, the first projection
The center of 224' is Chong Die with the center in the first gap, i.e., in the center of first light source 244 and the first gap
Heart position is located along the same line.
Since the center of first light source is most bright, the center in the second gap is most dark, the embodiment of the present application pass through by
The center of first light source and the center in the second gap are correspondingly arranged, and can be further reduced the firefly of second light source
Phenomenon.
