Problems solved by technology

[0006] However, billboards using LEDs have the following disadvantages: an external voltage is applied to the LEDs, a large number of LEDs are connected to each other, a substrate for wiring (that is, a substrate for printed wiring circuits), and electronic connection between the substrate and the LEDs. And the mounting of mechanical attachment and the formation of metal wiring should be performed by individually controlling the externally applied voltage of each LED, and its shape is limited to the flat panel type

Abstract

Provided are a display device in which a shape is not limited, the mounting and wiring of elements are not required, visibility, luminance, and the representation of a color are excellent, brightness is adjustable, production cost is low, and fabrication is easy, and a fabrication method thereof. Specifically, the display device includes: a substrate; a light emitting layer formed on the top of the substrate in a predetermined pattern and containing quantum-dots that receives external light to emit light; and a light emitting element providing the external light to the light emitting layer.

Description

technical field [0001] The present invention relates to a display device, and more particularly, to a new electric sign having free-form and excellent color display, capable of controlling brightness and having excellent visibility and excellent publicity effect. Background technique [0002] Modern indoor and outdoor billboards can generally be divided into billboards for indirect lighting using fluorescent lamps, incandescent bulbs, tungsten, etc., and billboards for direct lighting using neon lights, light emitting elements, and the like. These advertising boards can only be installed at limited positions due to size, weight, etc., and become a major factor that hinders the beauty of the city and the like. [0003] Indirectly lit billboards can be easily manufactured at very low cost and are therefore most commonly used. Advertising methods by using paint on an organic / inorganic substrate, or forming sentences, etc. on a transparent substrate portion by using etching or ...
