Abstract

The invention discloses an LED device, a fabrication method thereof and a display panel. The LED device comprises a device structure layer, wherein the device structure layer comprises a first semiconductor layer, a light-emitting functional layer and a second semiconductor layer which are sequentially arranged, the LED device also comprises a light-emitting layer, and the light-emitting layer isarranged on a peripheral side surface of the device structure layer. The display panel comprises a transparent first substrate and a plurality of LED devices, wherein the plurality of LED devices arearranged on the first substrate, and light can be emitted simultaneously from a top surface and a bottom surface of each LED device; with the arrangement of the light-emitting layer, the light giving-out brightness of the top surface and the bottom surface of the LED device is further improved, thus, the display panel proposed by the embodiment is a transparent display panel and has relatively high transmittance, and the requirement of a user on the transmittance of the display panel can be met.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an LED device, a manufacturing method thereof, and a display panel. Background technique [0002] With the development of technology, there have been transparent display panels installed on glass windows. This panel can not only be used for display, but also people can see the items behind the window through the display panel. In order to improve the cleanliness of items behind the viewing window, users have higher and higher requirements for the transmittance of transparent display panels. [0003] Existing transparent display panels mainly include transparent liquid crystal display panels and transparent OLED display panels. figure 1 It is a structural schematic diagram of a transparent liquid crystal display panel, figure 1 The shown transparent display panel includes an array substrate 11 and a color filter substrate 12 arranged in opposite positions, and also includes a l...
