Embodiment Construction

[0056] In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. Throughout the specification, the same reference numerals denote the same elements. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected to" another element, it can be directly on or connected to the other element, or Intermediate elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements present. As used herein, "connected" may refer to physical and / or electrical connection. Furthermore, "electrically connected" or "coupled" may mean that other elements exist between two elements.

[0057] As used herein, "about," "approximately," or "substantially" includes stated values ​​and averages within acceptable deviations from a particular value as determined by one of ordinary skill ...

Abstract

The present invention relates to a display device and a forming method thereof. The display device includes a substrate, a first shielding layer, a first insulating layer, a micro light emitting element, a second insulating layer and a micro control chip. The substrate has an outer surface and an opposite inner surface. The outer surface serves as a viewing surface. The first shielding layer is disposed on the substrate and has an opening. The first insulating layer is disposed on the first shielding layer. The micro light emitting element is located on the first insulating layer, and the opening corresponds to the micro light emitting element. The micro light emitting element includes a first contact, a light emitting layer, and a second contact. The second insulating layer is disposed over the micro light emitting element and the first insulating layer and covers the micro light emitting element. The micro control chip is disposed on the second insulating layer. The micro control chip has a first pad corresponding to one of the first contact and the second contact of the micro light emitting element to be electrically connected to the corresponding micro light emitting element.

Description

technical field [0001] The present disclosure relates to a display device, and in particular to a display device with micro light-emitting elements. Background technique [0002] In recent years, people's demand for display devices has increased, and research on display devices has also been progressing. Although there have been many developments in the field of display devices, there are still many different problems in various display devices to be further overcome. Contents of the invention [0003] The present disclosure relates to a display device including at least one micro control chip and a plurality of micro light emitting elements, which can provide more accurate alignment and better connection effect between the micro control chip and the micro light emitting elements. The yield rate can be better, and the maintenance of the micro control chip can be more convenient. [0004] According to an aspect of the present disclosure, a display device is provided. The...
