Embodiment Construction

[0024] Reference will now be made in detail to the embodiments herein, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. However, this document may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

[0025] Ranges can be expressed herein from "about" one particular value, and / or to "about" another particular value. When such a range is expressed, another embodiment includes from the one particular value and / or to the other particular value. Similarly, when values ​​are expressed as approximations, by use of the antecedent "about," it will be understood that the particular value forms another embodiment. It will be further understood that the endpoints of each range are both significant relative to, and independent of, the other endpoint.

Abstract

A sub-display for a tiled display includes a central region and first peripheral region. The central region includes an array of pixels where each pixel includes a first area and at least one first light source. The first peripheral region includes an array of first sub-pixels where each first sub-pixel includes a second area and at least one second light source. Each second area is smaller than each first area and each second light source emits less optical flux than each first light source.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application No. 62 / 564,578, filed September 28, 2017, which is the basis of this application and is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates generally to tiled displays. More particularly, the present disclosure relates to tiled micro LED (microLED) displays that include multiple sub-displays arranged adjacent to each other to form a larger display. Background technique [0004] Large area displays may not be practical to fabricate on a single large area substrate. For example, the size of a display may be larger than existing processing equipment can handle and / or the yield of a large display size may be much lower than that of a smaller display size. In these cases, it is advantageous to manufacture the display by stitching together multiple smaller sub-displays. The tiling of smaller sub-displays ...
