Abstract
The present invention relates to a dot matrix display for combined lens light focusing type light emitting diodes. Light emitting diode chips are ranged in a dot matrix mode on a circuit substrate, an external conductor is led out, reflection cavity holes are arranged on the circuit substrate, each of reflection cavity holes respectively corresponds to each light emitting pixel point and is sealed by a plurality of epoxy resin convex lenses, each convex lens respectively corresponds to each of the light emitting diode chips in the reflection cavity holes, and the light emission angle of each of the light emitting diode chips is regulated by the curvature and the convexity of each convex lens. The display has the characteristics that each light emitting pixel is composed of a plurality of convex lenses according to the number of the light emitting diode chips, each chip is positioned in the central position of each convex lens, and thereby, the good color mixing effect of each chip can be realized; dot matrices are used for package, the pixel density of the unit area of an outdoor display screen can be improved, the definition of pictures can be strengthened, cost can be lowered, and functions can be improved.
Description
Technical field
The invention belongs to the indicating device or the circuit engineering field that show variable information with quiescent processes, be specifically related to a kind of electronic color display of making light source of diode.
Technical background
Light-focusing type LED array display of the prior art, usually by circuit base plate, the shell of light-emitting diode chip for backlight unit that dot matrix is arranged and band reflection cavity is formed, and each reflection cavity shell is sealed by formed in mould epoxy resin convex lens.It overcomes the deficiency of flat-panel screens, the luminous intensity height, and the optically focused performance is good.If but in a pixel encapsulation a plurality of different colours light-emitting diode chip for backlight unit, because each chip position departs from same convex lens, can not keep the parallel of normal, therefore the vision acceptor is very big at the aberration of different coloured light that angle is experienced, and the colour mixture effect of a plurality of chips is bad in the same pixel.
The present invention is directed to the prior art above shortcomings, purpose is to provide a kind of each light emitting pixel point being made up of a plurality of convex lens according to what of light-emitting diode chip for backlight unit, and make each chip all be in the center of each convex lens, thereby realize the lens combination converged LED array display of the colour mixture effect that each chip is good.
Summary of the invention
A kind of lens combination converged LED array display, it has a circuit base plate, dot matrix arranging light emitting diode chip on the circuit base plate, and draw outer lead, circuit base plate is provided with the shell of band reflection lumen pore, and each reflects respectively corresponding each the light emitting pixel point of lumen pore.Respectively reflecting on the lumen pore by a plurality of epoxy resin convex lens sealings of described shell, convex lens are corresponding one by one with each light-emitting diode chip for backlight unit in the reflection lumen pore, by the curvature of convex lens and the light emission angle of protrusion height adjusting light-emitting diode chip for backlight unit.
Adopt the present invention of said structure to have the following advantages:
1. corresponding convex lens of each chip both can improve the luminosity of each pixel, can solve the inconsistent problem of each chip light emitting colour mixture angle of same pixel again.
2. owing to adopt the form of dot matrix encapsulation, be different from general outdoor display screen light-emitting component: as lightening tube etc., and can significantly reduce the diameter of each light emitting pixel, thereby the light emitting pixel density (picture element density than lightening tube improves 2.5-6.5 doubly, even higher) that improves the outdoor display screen unit area greatly strengthens image sharpness.Also can simplify the manufacture craft of outdoor display screen, reduce cost greatly, improve function.

Fig. 2 is the sectional view of this lens combination converged LED array display;
Fig. 3 is the planimetric map of this lens combination converged LED array display.
Embodiment
As depicted in figs. 1 and 2, the bottom of lens combination converged LED array display is a circuit base plate 5, dot matrix arranging light emitting diode chip 4 on it, and draw outer lead 3.Cover one plastic casing 2 on the circuit base plate 5, plastic casing 2 dot matrix are established 6, four light-emitting diode chip for backlight unit of reflection lumen pore 4 and are constituted a light emitting pixel point, and reflection lumen pore 6 is corresponding one by one with each light emitting pixel point that dot matrix is arranged.Each reflects on the lumen pore 6 by 1 sealing of four epoxy resin convex lens again, and interior each light-emitting diode chip for backlight unit 4 of epoxy resin convex lens 1 and reflection lumen pore 6 is corresponding one by one, forms a complete display thus.The light intensity of light emitting pixel point and angle can be adjusted the curvature and the height of projection of epoxy resin convex lens 1 and control when sealing.
Can encapsulate the light-emitting diode chip for backlight unit of a plurality of different colours in each light emitting pixel point of the present invention as required.
