The secondary object of the present invention is to provide a light-emitting diode display module which is convenient to set up and easy to collect. Since the pitch adjustment mechanism is adjusted and folded, the volume can be greatly reduced and the collection is convenient. When the display module is erected, the spacing adjustment mechanism can adjust the position on the spot according to different requirements such as brightness, space size, lamp point spacing, and line-of-sight penetration effect, so that the display module is presented in a relative size. Come out, especially suitable for the effects of short-term performance activities.

To achieve the above object, the present invention mainly comprises a plurality of light-emitting units, at least one set of pitch adjustment mechanisms, and the pitch adjustment mechanism is a telescopic fence structure or a grid-like telescopic fence structure. The light emitting unit is a light source having light emitting diodes of red light, green light and blue light, and the plurality of light emitting units are distributed at different positions on the members of the pitch adjusting mechanism. When the distance adjustment mechanism is adjusted, at least the spacing of some adjacent light-emitting units can be changed, and the position of at least some of the light-emitting units is also changed after the adjustment, so that the display module can exhibit another length and width. Size mode.

In order to make the reviewer clearly understand the detailed process and technical content of the present invention, the inventors will cooperate with the following drawings and detailed explanations, so that the reviewing committee can clearly understand the spirit of the present invention:

As shown in the first and second figures, a plan view of the unfolded and collapsed state of the present invention is shown. The LED display module 100 of the present invention mainly includes a plurality of light-emitting units 1 and at least one set of pitch adjustment mechanisms 2. The plurality of light emitting units 1 are distributed at the members of the pitch adjusting mechanism 2. When the pitch adjustment mechanism 2 is in a different unfolded state or in a folded state, it is a rectangular-shaped fence shape that exhibits different sizes. When the adjustment mechanism 2 adjusts, at least the spacing of the adjacent adjacent light-emitting units 1 can be changed, and the position of the partial light-emitting units 1 is also shifted while the pitch is changed, so that the length of the display module 100 is long. The distance in at least one of the wide sizes may be adjusted to change. The light emitting unit 1 is a light source having light emitting diodes of red light, green light, and blue light. Therefore, the pitch adjustment mechanism 2 forms rectangles of different sizes according to the degree of expansion. At this time, the distribution positions of the plurality of light-emitting units 1 are also different, so that the display module 100 can be adjusted to an appropriate position according to the installation location. The spatial form is matched to produce a relative light image.

In the present invention, the pitch adjustment mechanism 2 can be realized by a plurality of different structures, so that the length and width dimensions of the display module 100 can be changed differently, for example, only in one direction, uniaxial (x-axis or y). The position of the axis is adjusted, or the position of the two axes (x-axis and y-axis) is changed at the same time. The following is illustrated in several different embodiments.

As shown in the second figure. The lamp fixing strips 21 are in the shape of a strip. The plurality of light-emitting units 1 are disposed on the same side of the lamp fixing strip 21, and the spacing between the adjacent two light-emitting units 1 on the lamp fixing strip 21 is the same. The lighting unit 1 is a basic pixel unit of a display screen.

In the above embodiment, the link group 22 is constituted by a plurality of links connected in a staggered manner (like an X shape), and it is ensured that the plurality of lamp fixing bars 21 can be moved in parallel with each other. In this embodiment, the distance between the light-emitting unit 1 and the lamp fixing bar 21 is a fixed value. However, the spacing of the adjacent lamp fixing strips 2 can be adjusted and changed, and the spacing can be determined by the angle between the two links in which the link group 22 is staggered. In other words, the display module 100 of this embodiment can be adjusted only by a single axis. In addition, the electric wires connected between the light-emitting units 1 are hidden inside the lamp fixing bar 21, and are matched with the display module 100 by at least one power supply, a control device, etc. (not shown). The connection is made, so that when the position of the plurality of the light-emitting units 1 is changed, that is, the distance between the light points is changed, the display module 100 can still operate smoothly. The large-area display screen can be composed of a set or complex array display module 100.

Thereby, the display screen of the present invention can be erected by a set or multi-array display module 100 according to the display requirements of the use place and different pitches, and supplemented by horizontal or vertical dimension adjustment and matching appropriate lamp points.
