The transparent electrode pattern 121 is disposed along a first direction among the surface directions of the transparent cover 11, and a plurality of first spaced apart from each other with a portion in which the surface-mounted LED unit 122, which will be described later, is positioned. A plurality of first electrode portions 121a including electrodes 121a1 may be included.

In addition, the transparent electrode pattern 121 extends along a second direction crossing the first direction among the surface directions of the transparent cover 11, and extends across a portion where the surface-mounted LED unit 122 to be described later is located. It may include a second electrode portion 121b forming a common electrode. For example, the first direction may be a longitudinal direction, and the second direction may be a transverse direction.

The transparent electrode pattern 121 may include a vertical-horizontal electrode design in which continuous-discontinuity is repeated so that contact with the LED unit 122 is possible.

This signboard module deposits a specific transparent electrode pattern 121 in a continuous-discontinuous format designed as described above on the rear surface of the transparent cover 11, which is the front part of the signboard module, to control the operation of the LED unit 122. Anode & cathode line can be formed. For reference, one of the first electrode part and the second electrode part may be an anode, and the other may be a cathode.

In addition, the transparent electrode pattern 121 may be composed of transparent electrode materials such as Indium Tin Oxide (ITO), Indium Zinc Oxide (IZO), liquid polymer, etc. to maintain the transparency (light transmittance) of the panel unit 1. . In addition, the transparent electrode pattern 121 may be formed by a low-cost patterning method using a laser, which has been difficult to apply in the conventional outdoor signboard LED-solar cell module manufacturing method.

In addition, referring to FIGS. 6 and 7, the LED structure 12 is a surface-mounted LED unit provided on the rear surface of the transparent cover 11 so as to be electrically connected to the transparent electrode pattern 121 (for reference, the present application is A'surface mount type LED unit' and a'LED unit' are mixed, and the'surface mount type LED unit' and the'LED unit' may mean the same configuration) 122 may be included. The surface-mounted LED unit 122 may electrically connect a plurality of first electrodes 121a1. In other words, the surface-mounted LED unit 122 may electrically connect the first electrode 121a1 and the neighboring first electrode 121a1 spaced apart from each other with a portion at which the LED unit 122 is positioned therebetween. In addition, the surface LED unit 122 may be electrically connected to the second electrode part 121b. At this time, the first electrode 121a1 may be electrically connected to the neighboring first electrode 121a1 by a bridge role of the surface-mounted LED unit 122, and the surface-mounted LED unit 122 forms a common electrode. It may be connected to the second electrode part 121b.

Specifically, referring to FIGS. 6 and 7 together, the surface-mounted LED unit 122 is formed at one end in the first direction and connected to the first electrode 121a1, the first terminal 1221, the first rudder A second terminal 1222 formed at an end portion and connected to the first electrode 121a1 adjacent to the first electrode 121a1, and a third terminal formed at one end portion in the second direction and connected to the second electrode portion 121b.

Production is possible.

In the case of conventional LED signboards, a series of anode line pattern electrodes formation, insulation layer formation and patterning for insulation of two lines, cathode line pattern electrode formation, in order, because the contact between anode and cathode and LED is required for LED signal control. As a result, in the case of a conventional LED signboard, the anode line pattern electrode and the cathode line pattern electrode are formed as separate layers from each other, and an insulating layer must be formed between the two layers. There was a big side.

However, according to the signboard module, the LED unit 122 is packaged in a surface mount type, and the first electrode part and the second electrode part forming the anode and the cathode are divided into a specific pattern (the first electrode part is divided into a plurality of first electrodes). Thus, the LED unit 122 is disposed to be spaced apart from each other, and the first electrode of the first electrode is formed as a spaced apart part (a part where the LED unit 122 is disposed), and the LED unit 122 By connecting the transparent cover 11 with the transparent electrode pattern 121 designed in a specific pattern on the rear surface of the glass to form the panel part 1, insulation of the first electrode part and the second electrode part is made even without an insulating layer.

For example, when the first electrode part 121a is an anode line and the second electrode part 121b is a cathode line, each of the plurality of first electrode parts 121a is a Red Anode, Green Anode, and Blue Anode, respectively. I can. In this case, the second electrode part 121b may be a common cathode. In addition, when the first electrode part 121a is a cathode line and the second electrode part 121b is an anode line, each of the plurality of first electrode parts 121a may be a Red Cathode, Green Cathode, and Blue Cathode, respectively. have. In this case, the second electrode part 121b may be a common anode. As such, there may be three first electrode portions 121a. As such, the LED unit 122 sets the first electrode part 121a (terminal electrode line) and the second electrode part 121b (cross electrode line) to one of the cathode and anode according to the transparent electrode pattern 121 that is in contact. Optional configuration is possible. For reference, in the drawings of the present application, each LED unit 122 consisting of 8 electrodes (terminals) is connected to the patterned wiring on the substrate with 6 contacts of the anode line of R, G, and B and 2 contacts of the common cathode line.

In this case, the first to fourth terminals 1221, 1222, 1223, and 1224 may have a suitable position on a surface from which light is emitted from the LED unit 122. For example, the packaging method of the LED unit 122 may be arbitrarily configured according to the side on which the LED emits light. For example, the configuration of the packaging of the LED unit 122 may vary depending on whether the light emitting side is the front or rear side. have. For reference, in the drawings of the present application, an LED unit 122 having a rear light emitting surface is shown.

In addition, the first to fourth terminals 1221, 1222, 1223, and 1224 are directly (directly) connected to the transparent electrode pattern 121 patterned on the transparent cover 11, and according to the above description, the first to fourth terminals 1221, 1222, 1223, and 1224 The distance between the terminals 1221, 1222, 1223, and 1224 or the positions of the first to fourth terminals 1221, 1222, 1223, and 1224 may be interdependent with the transparent electrode pattern 121.

In addition, the LED structure 12 may include a plurality of LED units 122. In addition, the LED units 122 may be disposed at intervals from each other. In addition, the LED units may be disposed adjacent to each other along each of the first and second directions. For example, it can be arranged in a checkerboard shape. Accordingly, the transparent electrode pattern 121 may be formed such that each of the plurality of first electrode units 121 and the second electrode unit 122 contacts each of the plurality of LED units 122.
