Embodiment Construction

[0083] Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numerals are used in the drawings and description to refer to the same or like parts.

[0084] 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 a physical and / or electrical connection. Furthermore, "electrically connected" or "coupled" may refer to the existence of other elements between the two elements.

[0085] As used herein, "about," "approximately," or "substantially" includes th...

Abstract

The invention discloses a display device comprising a pixel driving circuit, at least one first circuit electrode, at least one second circuit electrode, at least one first conductive pattern, at least one second conductive pattern and light emitting diode elements. The pixel driving circuit includes a power line, a transistor and a common line, wherein a first end of the transistor is electrically connected to the power line. At least one first circuit electrode is electrically connected to at least one of the second end of the transistor and the common line. At least one second circuit electrode is electrically connected to at least one of the power line and the common line. The material of the at least one first conductive pattern is the same as the material of the at least one second conductive pattern, and the thickness of the at least one first conductive pattern and the thickness of the at least one second conductive pattern have a difference. The light emitting diode element is disposed on the at least one first conductive pattern and is electrically connected to the at least one first conductive pattern. A method of manufacturing the above-mentioned display device has also been proposed.

Description

technical field [0001] The present invention relates to an optoelectronic device and a manufacturing method thereof, and more particularly, to a display device and a manufacturing method thereof. Background technique [0002] The light emitting diode display panel includes a driving backplane and a plurality of light emitting diode elements transposed on the driving backplane. Inheriting the characteristics of light-emitting diodes, light-emitting diode display panels have the advantages of power saving, high efficiency, high brightness and fast response time. In addition, compared with organic light emitting diode display panels, light emitting diode display panels also have the advantages of easy color adjustment, long luminous life, and no image burn-in. Therefore, light-emitting diode display panels are regarded as the next generation of display technology. However, the transposed yield of the light emitting diode elements of the light emitting diode display panel stil...
