Abstract
The invention belongs to the light-emitting diode (LED) technical field, in particular to a novel chip which can is suitable for being used as display pixels. Due to the fact that a geometric structure with an oval sectional area is adopted by a packaging lens, the LED light source disclosed by the invention is characterized in that in display screen applications, the horizontal raster is wide and the requirements of display screen applications are met. Due to the fact that an 'all-in-one' chip structure is adopted by the LED full-color display screen, the LED display screen disclosed by the invention is enabled to have the advantages that the pixel display is accurate, the video colors are realistic.
Description
Technical field
The invention belongs to the LED technical field, more specifically, relate to a kind of LED point-source of light and the manufacture method thereof that can improve the LED display display effect.
Background technology
In many application of LED, require led light source to have broad light territory in a certain dimension, such as in display screen technology, the spectators on the different directions need in the horizontal direction broad light territory so that can see continuous with consistent image, simultaneously, it then is not very high the light territory on the vertical direction being required.
On the other hand, because LED is angled, LED display has angle direction equally.Namely when different angles was watched, its brightness meeting is increasing or decreasing gradually.The angle consistency of three kinds of primary-color LEDs of RGB will directly affect the fidelity of vedio color.
Existing led light source for display screen, what generally take is circular or oval-shaped package lens.The brightness of this wafer housing on all directions is identical with light intensity, but can not satisfy display screen to the requirement of light territory and fidelity.
The present invention improves in the face of prior art from optical design and the material selecting party of package lens.
Summary of the invention
The present invention discloses the led light source that a kind of display screen is used, and this light source comprises one or more monomer chips, and several monomer chips are encapsulated in the same package lens jointly, and the cross sectional shape of package lens is oval.
Preferably, the one or more monomer chips in the led light source package lens are drawn package lens on the major semiaxis that encapsulates lens bottom surface ellipse.
Alternatively, the primary colours of the one or more monomer chips in the led light source package lens are identical or part is identical.
Alternatively, the primary colours of the one or more monomer chips in the led light source package lens are different.
Preferably, one or more monomer chip common anode or common cathode in the led light source package lens, the structure of formation N core N+1 pin.
Alternatively, the one or more monomer chips in the led light source package lens be in package lens that yi word pattern is arranged in order, complete overlapping arrangement or the arrangement that overlaps.
The present invention discloses the panchromatic display screen of a kind of LED in addition, and the pixel of this display screen is made of LED point-source of light disclosed by the invention, and wherein, the monomer chip that consists of the LED point-source of light is each one piece of the chip of three kinds of primary colours of red, green, blue.
The invention has the beneficial effects as follows:
Because it is oval-shaped geometry that package lens has adopted area of section, led light source disclosed by the invention has the characteristics that wide, the compound display applications of lateral light field width requires in the application of display screen.Because the LED full color display has adopted the chip structure of " Trinity ", so that LED display disclosed by the invention has advantages of that pixel shows more precisely, vedio color is more true to nature.

Fig. 1: the LED point-source of light in the preferred embodiment;
Fig. 2: Figure 1A-A view.
Specific embodiment
As shown in Figure 1, in a specific embodiment, the package lens of LED point-source of light 6 is interior have been inherited primary colours and has been respectively red 1, green 2, blue 3 and the monochromatic chip of white 4 four LEDs, the overlapping and shared anode pin 5 of the monochromatic chip dislocation of four LEDs.Pin 1-1, pin 2-1, pin 3-1 and pin 4-1 are respectively the negative electrode of redness 1, green 2, blueness 3 and 4 four monochromatic chips of white.Five pins are drawn package lens 6 on the major semiaxis that encapsulates lens bottom surface ellipse, form " four-core five pins " structure.
As shown in Figure 2, the cross sectional shape of package lens 6 is oval, and five pins are evenly distributed on the major semiaxis.
