Abstract
The utility model relates to a concentrating type light emitting diode (LED) dot matrix display which is composed of a circuit base board, a plastic shell without reflection chamber hole, an LED chip and an epoxy resin seal. The utility model realizes electric connection among diodes by the circuit board, and is packed by an epoxy resin plane or a convex lens; a light emitting angle in a light emitting spot is adjusted by the curvature and the convex height of the convex lens. The display overcomes the disadvantage of strengthening a dot separated sense of a colour video image because the reflection chamber isolates diffraction of light among light emitting pixels in the existing dot matrix displays. The image effect of the display is softer, the distance of optimum visual effects is shortened, and the utility model can increase image effects of a colour LED display screen.
Description
Technical field
The utility model belongs to indicating device or the circuit engineering field that shows variable information with quiescent processes, is specifically related to a kind of electronic color display of making light source of diode.
Background technology
LED array display in 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 by formed in mould epoxy sealing.But because the past does not have blue color chip, can't show the full color dynamic image, the therefore design of initial LED matrix display mainly is the demonstration of considering to be used for contents such as dynamic character pattern.Therefore adopt the plastic cement reflection cavity to isolate luminous point, diffraction of light and cause the fuzzy of picture and text between the picture element in the time of so both can avoiding showing picture and text also can be launched the light of non-normal direction simultaneously and reflex to normal direction by reflection cavity.And in recent years because the birth of blue color chip makes the LED matrix display progressively be used for the full color field of video displaying.And in the display application of color video image, the light isolation effect of reflection cavity has increased the weight of visual point-like and has separated sense, could realize the best visual effect on larger distance.
Summary of the invention
The utility model is at the prior art above shortcomings, purpose is to provide the LED array display in a kind of no reflection events chamber, between each light-emitting pixels because the effect of diffraction, therefore when the display color video image, visual effect is softer and lowered visual point-like greatly and separate sense, makes the distance of the best visual effect shorten greatly.
The technical solution of the utility model is as follows:
The LED array display in a kind of no reflection events chamber, it has a circuit base plate, dot matrix arranging light emitting diode chip on the circuit base plate, and draw outer lead, be characterized in that circuit base plate is provided with the shell of not being with the reflection lumen pore, go up by epoxy resin convex lens or flat seal, the curvature of convex lens and protrusion height are regulated the light emission angle of light-emitting diode chip for backlight unit.Planar package then can be by the diffracting effect between the light-emitting pixels how much controlled that adds diffusant, thereby regulates the soften of its image quality.
Adopt the following advantage that the utlity model has of said structure:
1, the LED matrix display in no reflection events chamber, because the effect of diffraction, therefore when the display color video image, visual effect is softer and lowered visual point-like greatly and separate sense, makes the distance of the best visual effect shorten greatly between each pixel.
2, the cancellation reflection cavity makes that the lighting angle of light-emitting pixels is bigger, more helps the manufacturing of color LED display screen with great visual angle.

Fig. 3 is the sectional view (plane form) of this no reflection events chamber type LED array display;
Fig. 4 is the planimetric map of this no reflection events chamber type LED array display.
Embodiment:
Be described further below in conjunction with drawings and Examples:
As depicted in figs. 1 and 2, its bottom line base board 5, dot matrix arranging light emitting diode chip 4 on it, and draw outer lead 3.Circuit base plate 5 covers one plastic casing 2, by epoxy sealing, the epoxy encapsulation position relative with each light emitting pixel forms convex lens 1, forms a complete display thus.The light intensity of light emitting pixel and angle can epoxy resin convex lens 1 height of projection be controlled when sealing.
As not adopting convex lens 1, can adopt plane 6 encapsulation, before sealing and curing, in epoxy resin, add diffusant then as required, referring to Fig. 3.
Can encapsulate the light-emitting diode chip for backlight unit of a plurality of different colours in each luminous point of the present utility model as required, referring to Fig. 4.
Claims (4)
1, the LED array display in a kind of no reflection events chamber, it has a circuit base plate, dot matrix arranging light emitting diode chip on the circuit base plate, form light emitting pixel, and draw outer lead, it is characterized in that establishing on the described circuit base plate shell of a no reflection events lumen pore, the direct encapsulating epoxy resin of the light-emitting diode chip for backlight unit of each light-emitting pixels on the circuit base plate.
2, the LED array display in no reflection events according to claim 1 chamber is characterized in that the epoxy encapsulation position relative with each light emitting pixel forms convex lens.
3, the LED array display in no reflection events according to claim 2 chamber is characterized in that the light emission angle of regulating luminous point by the curvature and the protrusion height of convex lens.
