Description

LED display unit that is easy to adjust the angle.}

The present invention relates to an LED display unit that is easy to adjust the angle, and more specifically, to an LED that constitutes an electronic signboard and allows the angle to be adjusted during installation, so that the angle can be easily changed depending on the installation location. It's about the display unit.

In general, electronic signboards such as digital signage combine multiple LED display units up, down, left, and right, and are unitized so that the screen size can be adjusted and installed according to the user's needs. Each unit is combined up, down, left, and right to create one screen. It is configured to be implemented as a display.

In a conventional LED display unit, as in Korean Patent No. 10-2010709, multiple LED modules are combined in front of the cabinet frame, and in the process of combining the LED modules to the cabinet frame, multiple cables such as power cables and data cables are connected. Since it is configured to be combined with each LED module, it takes a lot of time for wiring work when workers install the LED display unit, and it is difficult for general consumers, not professional workers, to install or repair it.

In addition, the conventional LED display unit is installed vertically on the ground, so when viewed from a position other than horizontal to the LED display in an auditorium or crowded space, the screen displayed on the LED display is affected by the angle of light reflection, etc. There was a problem that made it difficult to recognize.

The present invention was created to solve the above problems. The purpose of the present invention is to provide an LED display unit that is easy to adjust the angle of the LED display so that the screen displayed on the display can be easily recognized from various positions. It is provided.
