Systems and methods of forming a video display

An information handling system may include an organic light-emitting diode (OLED) display layer of a video display to display an image to a user; an A-cover forming a housing behind the OLED display layer; and a physically bifurcated display daughter board between the OLED display layer and the A-cover, the physically bifurcated display daughter board including: a first portion of the display daughter board including a source driver integrated circuit (IC) operatively coupled to a processor to receive graphics data; and a second portion of the display daughter board comprising a power management integrated circuit (PMIC) operatively coupled to the first portion and a power source; the second portion of the display daughter board being mechanically coupled to an interior surface of the A-cover to dissipate heat away from the OLED display layer.

An ink jet process is used to deposit a material layer to a desired thickness. Layout data is converted to per-cell grayscale values, each representing ink volume to be locally delivered. The grayscale values are used to generate a halftone pattern to deliver variable ink volume (and thickness) to the substrate. The halftoning provides for a relatively continuous layer (e.g., without unintended gaps or holes) while providing for variable volume and, thus, contributes to variable ink/material buildup to achieve desired thickness. The ink is jetted as liquid or aerosol that suspends material used to form the material layer, for example, an organic material used to form an encapsulation layer for a flat panel device. The deposited layer is then cured or otherwise finished to complete the process.
