    Abstract: Printed micro-LEDs have a top metal anode electrode that is relatively tall and narrow and a bottom cathode electrode. After the LED ink is cured, the bottom electrodes are in electrical contact with a conductive layer on a substrate. The locations of the LEDs are random. A thin dielectric layer is then printed between the LEDs, and a thin conductive layer, such as a nano-wire layer, is then printed over the dielectric layer to contact the anode electrodes. The top conductive layer over the tall anode electrodes has bumps corresponding with the locations of the LEDs. An omniphobic liquid is then printed which only resides in the “low” areas of the top conductive layer between the bumps. Any optical material is then uniformly printed over the resulting surface. The printed optical material accumulates only on the bump areas by adhesion and surface tension, so is self-aligned with the individual LEDs.

    Abstract: On a flexible substrate is printed, LEDs, a battery, a flasher, and an actuator. The actuator may be a photo-switch that causes the battery and flasher to periodically energize the LEDs when a sufficient ambient light impinges on the actuator. The substrate may be an insert in a transparent package containing a product, such as a razor. When the package is in the front of a display in a store, the ambient light causes the LEDs to flash, such as every 10-30 seconds to attract consumers to the product. The substrate may also form part of the outer surface of the package. The flasher may simply flash the LEDs or create a dynamic display by energizing different groups of the LEDs at different times.

    Abstract translation: 在柔性基板上印刷，LED，电池，闪光器和致动器。 致动器可以是光电开关，当足够的环境光照射在致动器上时，该光开关使得电池和闪光器周期性地给LED供电。 衬底可以是包含诸如剃刀的产品的透明包装中的插入物。 当包装在商店中的显示器的前面时，环境光使LED闪烁，例如每10-30秒吸引消费者使用该产品。 衬底也可以形成封装的外表面的一部分。 闪光灯可以简单地闪烁LED或通过在不同时间激励不同组的LED来创建动态显示。
