Description

TRANSPARENT DISPLAY BOARD TO EXPAND THE LIGHT-EMITING AREA "

The present invention relates to a transparent electric display panel capable of expanding a light emitting area, and more particularly, to a transparent electric display panel capable of expanding a light emitting area by integrating one or more light emitting elements at a light emitting point of a transparent electric display board, The present invention relates to an electric sign board.

Generally, outdoor light emitting devices are widely used as neon lights, cold cathode lamps (CCL), and light emitting diodes (LEDs). As a light emitting device used in the room, an external electrode fluorescent lamp (EEFL), a cold cathode fluorescent lamp (CCFL), a light emitting diode electric signboard, and the like are used.

Here, the neon or cold cathode discharge tube uses a high voltage power source, consumes a lot of power, has a risk of electric shock and fire, and has a short life span. In addition, since EEFL and CCFL use high frequency, they are difficult to use outdoors, have a low illuminance and short life span.

Further, in the case of a light-emitting panel using an LED, the back surface of the light-emitting surface is blocked by the cover by the processing of the electric wire on the rear surface or the black film processing, and the light is emitted in only one direction.

On the other hand, in recent years, the light emitting device has been widely used as an advertising signboard rather than merely a function of lighting, and in a design with an aesthetic sense added to the interior.

However, the above-described light emitting devices have limitations in providing aesthetic senses due to restrictions on the size of the lamp, the size of the stand supporting the light emitting device, and the like.

Therefore, conventionally, in order to apply the aesthetic sense as described above, a plurality of light emitting devices are attached to a transparent electrode, and a transparent electric display panel Was released. In such a transparent electric display panel, a plurality of light emitting devices are connected to a transparent electrode, and a light emitting device having three electrodes and four electrodes is usually applied.

However, recent buyers are demanding products that can produce more colors, lights, and images. Therefore, the conventional transparent electric billboard has been expanding the substrate area of the transparent electric billboard, and mounting a larger number of light emitting elements, thereby bringing products that meet the needs of the buyer.

However, such a conventional transparent electric display panel basically increases the area of the substrate in order to increase the number of the light emitting devices, and therefore, it can only be produced in a large-sized product, resulting in high manufacturing and purchasing costs.

Korean Registered Patent No. 10-1584739 (registered on June 06, 2016) Korean Patent Publication No. 10-2009-0030796 (published on Mar. 25, 2009)

The first to third electrodes 211 to 213 and 221 to 223 are light emitting electrodes that emit light in any one of R, G, and B, and the fourth electrodes 214 and 224 correspond to a common electrode.

In this case,

The first wiring pattern 110 extends in the longitudinal direction from the starting end 101 to which the transmitting portion 300 is connected and is bent to the light emitting point A side and extends horizontally. At this time, the first wiring patterns 110 are commonly connected to the first mounting patterns 111 and 112 having the same number as that of the light emitting devices 210 and 220. The regions where the first wiring patterns 110 and the first mounting patterns 111 to 115 are connected are as shown in FIG.

In addition, the first mounting patterns 111 and 112 are formed with a coating region to which a conductive adhesive is applied, and a barrier pattern (not shown) is formed at a boundary between the first and second mounting patterns 111 and 112 so as to prevent the conductive adhesive, 160 < / RTI >

As shown in the drawing, the shielding pattern 160 is divided into at least one horizontal line and / or a vertical line between two first mounting patterns 111 and 112 spaced apart from each other and another adjacent mounting pattern, So that it is prevented from flowing into the mounting pattern.

Referring to FIG. 5, the second wiring pattern 120 extends in the longitudinal and lateral directions at the start end 101 and is connected to all the second mounting patterns 121 and 122 formed at the light emitting points. The second mounting patterns 121 and 122 are divided into the blocking patterns 160 and the width adjusting patterns 150 'and the length adjusting patterns 170. The second mounting patterns 121 and 122 are formed by coating regions 121a and 122a to which a conductive adhesive is applied, Respectively.

The second mounting patterns 121 and 122 may be connected to the second wiring patterns 120 by being spaced apart from each other with the first wiring patterns 110 or the other mounting patterns 111 and 112 interposed therebetween, And two patterns sequentially extend from the pattern 120.

At this time, the third mounting patterns 131 and 132 are spaced apart from each other with the fourth mounting patterns 141 and 142 interposed therebetween, and are sequentially connected to the third wiring patterns 130.

In the two third mounting patterns 131 and 132 shown in the figure, the third electrode 213 of the first light emitting device 210 and the third electrode 223 of the second light emitting device 220 are mounted, So that a region where the conductive adhesive is applied is formed.

Referring to FIG. 6, the fourth wiring pattern 140 includes a first wiring pattern 140 and a second wiring pattern 142 on which the fourth electrodes 214 and 224, which are common electrodes of the first light emitting device 210 and the second light emitting device 220, 4 mounting patterns 141 and 142 and may be set as a remaining region except for the first to third wiring patterns 110 to 130 in the entire transparent plate 100. [ .

The fourth wiring pattern 140 includes two fourth mounting patterns 141 and 142 in which the fourth electrodes 214 and 224 of the first light emitting device 210 and the second light emitting device 220 described above are mounted, ).

The fourth mounting pattern 141 on which the fourth electrode 214 of the first light emitting device 210 is mounted may include a second mounting pattern 122 on which the second light emitting device 220 is mounted, 132 extending between the first and second wiring patterns.

As described above, a wiring batten grouped at one or more ends and connected at a start end 101 is connected for each light emitting point, and each light emitting point is formed by grouping at least one light emitting element. At this time, each of the wiring patterns 110 to 140 extending for each light emitting point A is connected to a mounting pattern in which electrodes for outputting light of different colors are mounted.

That is, any one of the wiring patterns 110 to 140 is commonly connected to two mounting patterns in which electrodes emitting light of the same color are mounted. Therefore, in the present invention, one or more light emitting elements may be disposed at one light emitting point.

The width adjusting patterns 150 and 150 'and the length adjusting patterns 170 and 170' may be formed by increasing or decreasing the width and length of the area connected to the wiring patterns 110 through 140 in the mounting pattern, So that the sheet resistance value is uniform.

For example, it is preferable that the transparent electroluminescent panel keeps the luminance uniformly while enlarging the light emitting area of the light emitting point (A). The luminance of each of the electrodes 211 to 214 and 221 to 224 of the light emitting devices 210 and 220 is determined as a current value changed by the sheet resistance when a voltage of a certain level is supplied through the wiring patterns 110 to 140 . Accordingly, when the sheet resistance is different, the current value supplied to the electrode of each light emitting element is changed, so that the brightness between the electrodes becomes uneven.

Such a sheet resistance value can be calculated by the following equation (1).

[Equation 1]

MΩ = (L / W) × Ω

Where M? Is the sheet resistance, L is the length of the pattern, W is the width of the pattern, and? Is the unit sheet resistance.

The width adjusting pattern 150 is formed in a region extending from the first wiring pattern 110 to the first mounting pattern 121 on which the first electrode 221 of the second light emitting device 220 is mounted The insulating region is divided.

The width adjusting pattern 150 'is formed by dividing a region where the first wiring pattern 110 and the second wiring pattern 120 are insulated from each other to form the width of the first wiring pattern 110 and the second wiring pattern 120 The width was adjusted.

The length adjustment pattern 170 is formed to define sections that are interconnected by at least one of the first to third mounting patterns 111 to 112, 121, 122, 131, and 132, for example.

The length adjustment pattern 170 'is connected to the fourth wiring pattern 140 from the fourth mounting pattern 142 on which the fourth electrode 224 of the second light emitting device 220 is mounted And are longitudinally and longitudinally sectioned to increase the length.

That is, the width adjusting patterns 150 and 150 'are provided for increasing or decreasing the width of the pattern, and the width adjusting patterns 150 and 150' may be formed on the wiring patterns 110 to 130 and the mounting patterns 111, 112, 121, 122, 131, 132, The length adjustment patterns 170 and 170 'are for increasing or decreasing the length between the mounting pattern and the wiring pattern in which the electrodes are mounted. The length adjustment patterns 170 and 170' define one or more sections connected to each other so as to be mutually energized.

Therefore, according to the present invention, the width and length of the pattern connected to the electrodes for outputting light of the same color in the light emitting devices 210 and 220 in the light emitting point A are adjusted to have a uniform sheet resistance, Even if one or more light emitting devices 210 to 220 are mounted on the light emitting point A, light can be output with a uniform luminance. .

In the first embodiment, the two light emitting devices 210 and 220 are arranged on the upper and lower sides. Even if two or more light emitting devices are arranged in the vertical direction, The plurality of first mounting patterns 111 and 112 and the second mounting patterns 121 and 122 (hereinafter referred to as first columns) are aligned in the same direction and the third mounting patterns 131 and 132 and fourth The mounting patterns 141 and 142 (hereinafter referred to as the second row) are aligned in the same direction.

Therefore, in the first embodiment, the fourth wiring pattern 140 connected to the common electrodes (for example, the fourth electrodes 214 and 224) of each light emitting element is connected to the fourth electrode (not shown) of the first light emitting element 210 The first and second rows are spaced apart from each other and the fourth wiring pattern 140 is extended therebetween.

The features of the first embodiment will be described in more detail through the second embodiment. The second embodiment is an embodiment in which a larger number of light emitting elements are mounted in the vertical direction than in the first embodiment. Therefore, in the following, embodiments focusing on the connection structure between the light emitting element array and the wiring pattern in the light emitting element group 200 will be described.

However, the width adjusting patterns 150 and 150 'and the length adjusting patterns 170 and 170' are included in the following embodiments, but the drawings and description are omitted for the sake of simplicity.

Therefore, the first to fifth light emitting devices 210 to 250 are mounted in the direction in which the respective mounting patterns of the light emitting point A are arranged.

The wiring patterns 110, 120, 130, and 140 are grouped into four groups equal to the number of electrodes of the light emitting element, and each wiring pattern group extends to each light emitting point A.
