201007653 IX. Description of the Invention: [Technical Field] The present invention relates to an ultra-thin light-emitting diode display, and the display of the present invention can be applied to a single-segment LED, and can also be applied to a seven-segment display. Diode display bars, dot matrix squares, and other specialized displays for specific patterns and designs. "Previous technology" such a light-emitting diode display, as disclosed in the Chinese Patent ❹ φ pp. 1289947 (Application No. 095109119), "flexible LED surface light source structure, flexible board, and manufacturing method thereof ", as shown in the second picture. The flexible LED surface light source structure comprises: a flexible board having a first metal layer and a second metal layer, the first metal layer having a line layout, and the second metal layer being formed by a circle ϋ ίί On the flexible board, and the second metal layer has a highly reflective germanium layer 'except for a plurality of structural regions therein, the structural regions are electrically--, then - gold; and a plurality of the corresponding metal The mats are combined such that the f can be sourced via the first metal sound of the soft metal on the soft plate. With such a structure, there are several 2/2 layouts to lose =, shouting raw light; two inner _ = current and illuminating, the first metal layer input = mode must be combined with the layout on the soft board , its tree fg; ^^ two paved bare crystal at the point [invention content] J峨 not 4 phenomenon. In view of the above-mentioned conventional light-emitting diode display ultra-thin light-emitting two (four) display, the towel ^: 'This hair is for a τ located on the bottom surface of the transparent conductive film 5 201007653 = block resistance, so that the county diode obtains a certain range The current inside does not need to be fake and the resistance is 'second'. The top of the light-emitting diode is directly connected to the transparent conductive film of the top layer, and the top-shaped transparent surface is the anode thereof, and the bottom of the basin is bottom and bottom. Transparent guide and do the neopolar (eathGde), no need: help the solid crystal line; secondly, the top transparent conductive film is covered on the light-emitting diode - 'protected the light-emitting diode' no need to soften The glue is protected; finally, the reflective layer is provided on the bottom layer, so that the extraction can be finer than single-sided illumination, and the luminous efficiency is increased, so that there is no phenomenon that the light-emitting diodes are indistinct.超 The ultra-thin light-emitting diode display of the invention comprises: a drain, a transparent film, the bottom surface of which is a conductive film of the Weiwei Electric Power Circuit, and the circuit is mainly used as an anode of the light-emitting diode ( The base layer of the towel is a double-sided flexible circuit board for the second=, the substrate can be blackened and has a light-blocking layer, and the plurality of light-emitting diodes are drilled and drilled at the position of the ;; , coffin = the top layer is the same 'only the transparent conductive film is on, the transparent film is under, the transparent film is also engraved with the circuit' but its pattern is different from the electrical conductivity of the top transparent conductive film. 'The circuit will do a cathode of the light-emitting diode (cathQde), and fixing the function of the light-emitting diode; and a plurality of light-emitting diode crystal grains, which are disposed in the receiving hole of the intermediate layer; the ultra-thin light-emitting diode of the present invention When the polar body display j is used for single-sided illumination, an anti-riding can be added under the bottom layer to increase the overall luminous efficiency. The combination of the present invention has a thin light-emitting diode age _ combination: the remaining is transferred to the bottom, through, the grain position of the electric film, and then the intermediate layer is placed on the bottom layer; The dies are placed in the accommodating holes of the intermediate layer, and the illuminating crystal poles are turned up to the cathode; and then the circuit of the top layer of the silver paste is printed on the interfering layer. And above the middle layer of the top layer, the anode of the light-emitting diode die and the transparent conductive film of the top layer of the cathode and the bottom transparent conductive film are joined by silver enamel; to 6 201007653 The attachment between the layers is made of double-sided tape. _ The function of the ultra-thin light-emitting diode display is different after the ultra-thin light-emitting diode display is completed, because the transparent conductive film used by the top layer and the bottom layer is different according to the material and process used by the f The square resistance, so the matching, the working voltage of the light and the pole can be directly regarded as the current limiting resistor, and the heat generated by the light can be dissipated flat; and the circuit produced by the top layer is mainly used as the light emitting body 2 The anode and the formed postage form a bridge channel to the cathode of the inter-radial flexible circuit board at the connection position, thereby causing the current to pass through the illumination diode
