    Abstract: In one embodiment, a security label comprises a random arrangement of printed LEDs. During fabrication of the label, the LEDs are energized, and the resulting dot pattern is converted into a unique digital first code and stored in a database. The label is then attached to an object to be later authenticated, or the LEDs are printed directly on the object, such as a passport, license, bank note, certificate, etc. For authenticating the object, the LEDs are energized and the dot pattern is converted into a code. The code is compared to the first code stored in the database. If there is a match, the object is authenticated. The label may also have a printed second code associated with the first code, and both codes must match codes stored in the database for authentication. The general shape of the printed pattern may convey the proper orientation of the pattern.

    Abstract translation: 在一个实施例中，安全标签包括印刷的LED的随机排列。 在制造标签期间，LED被激励，并且所得到的点图案被转换成唯一的数字第一代码并存储在数据库中。 然后将标签附着到待认证的对象上，或者将LED直接打印在对象上，例如护照，许可证，纸币，证书等。为了认证对象，LED被激活，点图案 被转换成代码。 将代码与存储在数据库中的第一个代码进行比较。 如果有匹配，则对象进行身份验证。 标签还可以具有与第一代码相关联的打印的第二代码，并且两个代码必须匹配存储在数据库中的代码以用于认证。 印刷图案的一般形状可以传达图案的正确取向。

    Abstract: Ultra-thin flexible LED lamp layers are formed over a release layer on a substrate. The LED lamp layers include a first conductor layer overlying the release layer, an array of vertical light emitting diodes (VLEDs) printed over the first conductor layer, where the VLEDs have a bottom electrode electrically contacting the first conductor layer, and a second conductor layer overlying the VLEDs and contacting a top electrode of the VLEDs. Other layers may be formed, such as protective layers, reflective layers, and phosphor layers. The LED lamp layers are then peeled off the substrate, wherein the release layer provides a weak adherence between the substrate and the LED lamp layers to allow the LED lamp layers to be separated from the substrate without damage. The resulting LED lamp layers are extremely flexible, enabling the LED lamp layers to be adhered to flexible target surfaces including clothing.

    Abstract: A flexible light sheet includes a bottom conductor layer overlying a flexible substrate. An array of vertical light emitting diodes (VLEDs) is printed as an ink over the bottom conductor layer so that bottom electrodes of the VLEDs electrically contact the bottom conductor layer. A top electrode of the VLEDs is formed of a first transparent conductor layer, and a temporary hydrophobic layer is formed over the first transparent conductor layer. A dielectric material is deposited between the VLEDs but is automatically de-wetted off the hydrophobic layer. The hydrophobic layer is then removed, and a second transparent conductor layer is deposited to electrically contact the top electrode of the VLEDs. The VLEDs can be made less than 10 microns in diameter since no top metal bump electrode is used. The VLEDs are illuminated by a voltage differential between the bottom conductor layer and the second transparent conductor layer.

    Abstract: A flexible light sheet (24) includes a thin substrate (26) that allows light to pass through it, a transparent first conductor layer (28) overlying the substrate, an array of vertical light emitting diodes (VLEDs) printed as an ink over the first conductor layer, each of the VLEDs having a bottom electrode electrically contacting the first conductor layer, a dielectric material (36) between the VLEDs overlying the first conductor layer, and a transparent second conductor layer (38) overlying the VLEDs and dielectric layer, each of the VLEDs having a top electrode (12) electrically contacting the transparent second conductor layer. Each individual VLED may emit light bidirectionally. The VLEDs are illuminated by a voltage differential between the first conductor layer and the second conductor layer such that bidirectional light passes through the first conductor layer and the second conductor layer. Phosphor layers may be deposited on both sides to create white light using blue VLEDs. The transparent conductive layers may be contacted by bus bars (32; 34; 42; 40) which may be additionally connected to thin metal lines or a metal mesh in order to distribute the current homogeneously over the transparent conductive layer, in view of the high resistivity of transparent conductive layers.
