The full-color surface attaching type LED of a kind of miniaturization
Technical field
The utility model relates to LED manufacturing technology field, relates in particular to a kind of be used to the full-color surface attaching type LED of the miniaturization that high definition, high-contrast display screen are provided.
Background technology
LED (light-emitting diode) application is very extensive, full-color SMD (the surface attaching type provided due to prior art, Surface Mounted Devices), contrast, definition are not high, and the image fidelity degree is not high, can only be applied to the less demanding LED display of definition, LED size for the SMD technology is larger, and general corresponding image definition is lower, for the high definition LED display, pixel request is higher, just needs further to reduce the size of SMD LED.
The utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of miniaturization full-color surface attaching type LED.
To achieve these goals; the technical scheme that the utility model provides is: the full-color surface attaching type LED of a kind of miniaturization; comprise that the crystal-bonding adhesive that black BT resin plate reaches by fixed wafer is fixed on the luminescent wafer on described BT resin plate; between described luminescent wafer and BT resin plate, be connected with gold thread; on described gold thread and luminescent wafer, be packaged with the packing colloid for seal protection; described a plurality of black BT resin plate is combined to form a rectangle BT resin integral slab; described rectangle BT resin integral slab length is 1.0 millimeters, 1.0 millimeters of width.
Described luminescent wafer comprises red wafer, green wafer or blue light wafer, and described red wafer, green wafer or blue light wafer are pressed the yi word pattern order and arranged.
Compared with prior art, the utility model is simple in structure, by realizing the size microminaturization, the high definition of LED can be provided, realize high-contrast after making display screen, three kinds of color wafers adopt yi word pattern die bond mode simultaneously, therefore the coupling consistency height in three kinds of brightness of different angles red, green, blue is consistent, thereby make LED display the brightness matching consistency is fine at any angle, greatly improve the image fidelity degree.
The accompanying drawing explanation
Below utilize accompanying drawing to be further detailed the utility model, but the embodiment in accompanying drawing does not form any restriction of the present utility model.
Fig. 1 is the structural representation of the full-color surface attaching type LED of miniaturization described in the utility model.
Fig. 2 is surface attaching type LED chip encapsulating structure schematic diagram described in the utility model.
Embodiment
In order better to understand the technical solution of the utility model, describe below in conjunction with accompanying drawing the embodiment that the utility model provides in detail.
As depicted in figs. 1 and 2, the utility model embodiment provides a kind of miniaturization full-color surface attaching type LED, comprise the black BT resin plate 104 that conduction and supporting role are provided and be fixed on the luminescent wafer 101 on described BT resin plate 104, described luminescent wafer 101 is fixed on black BT resin plate 104 by the crystal-bonding adhesive of fixed wafer 105, between described luminescent wafer 101 and BT resin plate 104, be connected with the gold thread 102 for the chip surface electrode is connected with support, on described gold thread 102 and luminescent wafer 101, be packaged with the packing colloid 103 for seal protection, described a plurality of black BT resin plate 104 is combined to form a rectangle BT resin integral slab, described rectangle BT resin integral slab length is 1.0 millimeters, 1.0 millimeters of width, very miniaturization.
Described luminescent wafer comprises red wafer, green wafer or blue light wafer, described red wafer, green wafer or blue light wafer are pressed the yi word pattern order and are arranged, therefore the coupling consistency height in three kinds of brightness of different angles red, green, blue is consistent, thereby make LED display the brightness matching consistency is fine at any angle, reach better color vivid effect.
The utility model is simple in structure, by realizing the size microminaturization, can provide the high definition of LED, realize high-contrast after making display screen, greatly improves the image fidelity degree.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
