The structure of the LED light bar of composition and the structure of display screen.
Background technique
The light emitting end surface of chip is (i.e. using LED wafer largest light intensity direction as the flat of normal in LED element used at present
Face) with the welding plane of its pin or (can regard angle as is 0 °) parallel to each other or orthogonal (i.e. angle is 90 °).
Fig. 1 is common LED element structural schematic diagram, referring to Fig. 1, the light emitting end surface 18 of LED wafer 14 and the welding plane of pin 13
17 is parallel to each other.Chinese patent document CN201576681U is disclosed " a kind of LED packaging structure with lateral surface emitting light ", and Fig. 2 is that it shows
Be intended to, referring to fig. 2, claim is expressed, and omits in LED wafer 14(original image) light emitting end surface 18 and pin 13 welding it is flat
Face 17 is orthogonal (i.e. angle is 90 °).Fig. 3 is a kind of light distribution curve (the i.e. curve of light distribution of typical LED element
Figure), referring to Fig. 3, it is known that relative light intensity is maximum on 0 ° of direction (i.e. the normal direction of light emitting end surface) of distribution curve flux, be
100%.Above-mentioned two classes LED element is welded respectively when display screen, and the normal direction of light emitting end surface is generally all in horizontal direction.
