LED display device

Abstract

A display device according to an embodiment includes: a display substrate; a plurality of light emitting elements arranged on the display substrate; the injection molding layer covers the side surface of the light-emitting element and exposes the upper surface of the light-emitting element, and the light-emitting element comprises a first LED subunit and a second LED subunit; the second LED subunit is arranged on the first LED subunit; and a third LED subunit disposed on the second LED subunit, the third LED subunit being disposed closer to an upper surface of the light emitting element than the first LED subunit.

Description

technical field [0001] The present disclosure relates to a display device, in particular to an LED display device. Background technique [0002] Light-emitting diodes are widely used as inorganic light sources in various fields such as display devices, vehicle lamps, and general lighting. Light-emitting diodes are rapidly replacing existing light sources due to their long life, low power consumption, and fast response. [0003] In addition, existing light emitting diodes are mainly used as backlight sources in display devices. Recently, however, LED displays that directly realize images using light emitting diodes are being developed. [0004] Display devices usually utilize mixed colors of blue, green and red to achieve various colors. A display device includes a plurality of pixels to realize various images. Each pixel has blue, green, and red sub-pixels. The colors of these sub-pixels determine the color of a specific pixel, and a combination of these pixels realizes a...
