Fig. FIGS. 6 to 8 illustrate a method of designing a right angle triangular type LED module in which the LEDs are arranged in a triangular arrangement.

Since the right angle triangle type LED display device according to the present invention is used not only as a unit display device but also as another polygonal or polyhedron assembled with another right triangle type LED display device or the like, It is possible to display an undistorted image if the LED array is kept constant in the entire screen.

For this purpose, the right angle triangular type LED device according to the present invention has a triangular array of LEDs and a square LED module having the same number of LEDs in the horizontal and vertical directions as shown in FIG. 6, Lt; RTI ID = 0.0 > triangle < / RTI > type LED display.

7, the LEDs 25 are arranged at the same pitch on the first row 101 and the second row 102 (see FIG. 7) positioned below the first row 101, Of the LEDs 25 are arranged at the same pitch as the first row 101 and displaced to half the pitch of the LEDs in the horizontal direction. Thus, the LEDs of the second row 102 are positioned between two adjacent LEDs 25 of the first row 101 when viewed in the longitudinal direction. This is the same as [the LED of the first row 101 in the longitudinal direction is located between the two LEDs of the second row 102]. Thus, one of the LEDs 25 of the first row 101 and the two adjacent LEDs 25 of the second row 102 have an arrangement located at each vertex of the triangle. This relationship is also established between the LEDs of the second row 102 and the third row 103, the LEDs of the third row 103 and the fourth row 104, Can generally be described as the triangular arrangement of LEDs.

That is, even-numbered rows are shifted by 1/2 of the LED pitch in the horizontal direction relative to the odd-numbered rows, and the LEDs 25 are arranged in a zigzag arrangement in the vertical direction. And a triangle arrangement in which one LED 25 is located between two LEDs of a row positioned immediately below.

Referring to FIGS. 6 and 8, it can be seen that the LED module is divided into four types of right angle triangle type LED modules A, B, C and D by three design lines. A first design line L1 extending in the longitudinal direction from the center position in the horizontal direction on the basis of the rectangular LED module having the LEDs arranged in the same number as the even number of the LEDs in the triangular arrangement, The LED of the first row 101 closest to the first design line L1 is referred to as a first uppermost LED 101a and the first uppermost LED 101a is adjacent to the first design line L1 A second design line L2 extending between the adjacent LEDs 101b of the row in an inclined manner and an LED of the second row 102 closest to the first design line L1 to the second uppermost LED 102a ) Between the second highest-side LED 102a and an adjacent LED 102b of the second row immediately adjacent to the first design line L1 Standing inclined it is possible to design a third design four types of right-angled triangle-type LED modules that are separated by a line (L3) extending between the LED.

6, a square LED module having 42 LEDs in each of the horizontal direction and the vertical direction and each having an LED triangle arrangement is designed according to the design of the LED module for the design shown in FIG. . The first design line L1 extends longitudinally beyond the center between the 22nd LED of the first row 101 and the 21st LED of the second row 102 and the second design line L2 extends The third design line L3 extends obliquely between the 22nd LED and the 23rd LED of the first row 101 and the 20th LED and the 21st LED of the second row 102 are sloped And four types of right triangle type LED modules can be designed by the design lines.

In the four kinds of right angle triangle type LED modules (A, B, C, D) formed by such a designing method, when the A right triangle type LED module and the B right triangle type LED module are combined with each other, , C right angle triangle type LED module and D right triangle type LED module are connected to each other in height sides to form an inverted triangle shape of an equilateral triangle shape and the A, B, C, and D right triangle type modules are arrayed When combined, it forms a square screen. In the arrangement shown in FIG. 6, it is also possible to form a parallelogram screen when the C right-angled triangle-type LED module is moved to the side of the D right-triangle-type LED module and coupled.

Since the LED module has a predetermined direction, it is necessary to form a screen by combining the LED module in a non-rotated state. According to the present invention, four right-angled triangle type LED modules can be selectively assembled And it is possible to form various polygonal and polyhedral screens because the LED array and the outline of the polyhedron in the implemented screen can maintain a straight line. Also, since the right triangle type LED module formed according to the method of designing an LED module according to an embodiment of the present invention can form an equilateral triangle-shaped screen, it is possible to form a polygonal triangle-shaped polygonal screen.

According to the present invention, the sides of the right angle triangular type LED display device have recessed concave portions 15 between the protruding portion 16 and the protruding portion 16 where the LED 25 is located, It is possible. 5, it can be seen that all the height variations of the four types of right angle triangle type LED modules A, B, C, and D are extended in a zigzag shape.

When forming the four types of right angle triangular modules A, B, C and D by dividing the square type LED module having the triangular arrangement LEDs along the first, second and third design lines L1, L2 and L3, Each right-angled triangle-type LED module to be manufactured has a thickness corresponding to the thickness of the LED module 10. The right angle triangle type LED display device according to the present invention is formed into four types having right triangle LED modules A, B, C, and D, In addition, it is also possible to arrange the right angle triangle type LED display devices in a folded structure with respect to each other in order to realize a polyhedron type screen.

In other words, in the planar layout shown in FIG. 6, two opposing sides of the right triangle-type LED module must have a separation distance necessary for movement, so that it should be designed not to generate interference during rotation. In the case of a right triangle type LED module design, it is satisfied that the LED as a whole is uniformly arranged on the combined whole screen and that the LED modules combined with each other have a movable spacing relative to each other.

However, as shown in FIG. 8, when the LED is adjacent to the design line, as shown in the A right-angled triangle-type LED module and the B right-angled triangle-type LED module, If it is formed as a straight line, it can not have a set spacing space. However, in this case, as shown in the drawing, two opposing sides of the adjacent right-angle triangular LED module each have the protruding portion 16 and the recessed portion 15 and are extended in a zigzag shape, and one protruding portion 16 is provided on the other side It is possible to make a bonding with a spacing space necessary for bending without damaging the uniform arrangement of the LEDs.

FIG. 10 shows an example in which the A right angle triangle type LED module and the B right triangle type LED module shown in FIG. 9 are arranged in a bent manner with respect to each other. As shown in FIG. 8, the protrusion 16 and the concave portion 15, It can be seen that it can be folded without interference when it is extended in a zigzag form.

The zigzag-shaped sides allow the LEDs to be located inward from the sides of the LED module, allowing for the protruding portion to be provided not only in terms of securing spacing for bending, but also at the side of the LED adjacent to the sides. And an advantageous effect in terms of the protection of the LED. Therefore, the sides of the LED module can be designed in a zigzag shape with this intention.

Referring to FIGS. 6 and 8, four types of right angle triangular type LED modules are formed in a zigzag shape extending in height. However, they can be formed in a zigzag shape in which the diagonal sides are extended in zigzag shape according to the LED pitch.

A method of designing a right angle triangle type LED module according to another embodiment of the present invention shown in FIG. 11 is to explain a method of designing a right triangle type LED module in a case where LEDs are arranged in a regular array.

11 and 12, unlike the embodiment of the present invention, LEDs of the first row 201 and the LEDs of the second row 202 do not deviate from each other. That is, the LEDs are arranged on the straight line in the horizontal direction and the vertical direction and arranged at the same pitch. The array of such LEDs is generally referred to as a regular array.
