A hole extends through the lead frame between the first side and the second side.

Disclosed are various embodiments of methods, systems, devices and components for reducing power consumption in an LCD display that is backlit by LEDs. The various embodiments typically require the use of an array of backlighting LEDs disposed beneath and configured to emit light in the direction of an overlying LCD or LCD panel. In such an array, some LEDs are operated or driven at a first brightness, while other LEDs are operated or driven at a second brightness that is different from the first brightness, or at no brightness at all (i.e., such LEDs are turned off). LED brightnesses and therefore backlighting brightnesses over different portions of display or screen are varied and determined in accordance with the portion of display or screen that a user or processor has selected for viewing (“the area of interest”).
In an embodiment, the invention provides a multi-color illuminating back light structure comprising a light guide, a reflector, at least one LED and a wavelength converter material. Micro-structures are formed on a first surface of the light guide. The reflector is attached to the first surface of the light guide. A wavelength converter material is deposited on a second surface of the light guide. At least one LED is optically coupled to at least one side of the light guide. A portion of light reflected from the micro-structures and the reflector is converted into light having at least one wavelength different from the wavelength of the reflected light. The light leaving the wavelength converter material comprises light with at least first and second wavelengths.
An exemplary embodiment of an optical device may include a lead frame with a plurality of leads and a reflector housing formed around the lead frame. The reflector housing includes a first end face and a second end face and a peripheral sidewall extending between the first end face and the second end face. The reflector housing includes a first pocket with a pocket opening in the first end face and a second pocket with a pocket opening in the second end face. At least one LED die is mounted in the first pocket of the reflector housing, and a light transmitting encapsulant is disposed in the first pocket and encapsulating the at least one LED die.

A verifiable/copy-protected document features a combination of nearly identical line-screen patterns for embedding latent images within visually integrated settings. The latent images can be detected for purposes of verification with a matching viewer but are indistinguishable from their visually integrated settings under ordinary viewing conditions. The line-screen patterns, which can be incorporated into document artwork, are printed at certain combinations of line frequencies and print densities so that the line-screen patterns digitally reproduce as a largely undifferentiated solid tint.
A document and a related viewer for the document are constructed as image files capable of transmission to a printing site. The document file contains information for printing a document having hidden security indicia, and the viewer file contains information for printing a document viewer having a decrypting portion for revealing the hidden security indicia in the document.

Laminate documents (600, 700) include line-screen patterns (606, 608, 706, 708) for authenticating the documents. The line-screen patterns (606, 608, 706, 708) can hide information in the documents that can be revealed by a viewer (20). Print densities of the line-screen patterns (606, 608, 706, 708) can be adjusted to compensate for effects associated with lamination. A built-in viewer (612) can be spaced from the line-screen patterns to shift image intensity or color through rapid cycles of moiré interference with changes in viewing angle.

Copy protections are incorporated into print media by embedding a plurality of latent images formed by different line-screen patterns within a visually integrated setting formed by another different line-screen pattern. The different line-screen patterns of the latent images have line frequencies empirically selected so that upon reproduction at least one of the latent images is rendered more readily discernable to the unaided eye. A masking design formed by another line-screen pattern overlies both the latent images and the visually integrated setting.
A latent image (16) is incorporated into an apparent solid-color background (28) for representing a desired solid-color background having a target color. An underlying solid-color background (20) is printed on a print medium (18) using a first color composition that differs from the target color. Line-screen patterns (24) embedding a latent image (16) in a visually- integrated setting (26) are printed over the solid-color background (20) using a second color composition that differs from both the first color composition and the target color. The visual characteristics of the line-screen patterns (24) forming the latent image (16) and the visually integrated setting (26) are matched for rendering the latent image (16) practically indistinguishable from the visually integrated setting (26) without a visual aid (30). The print densities of the line-screen patterns and the first and second color compositions are interrelated so that the line-screen patterns (24) in combination with the underlying solid-color background (20) produce the apparent solid-color background (28) in the target color.
A compound security feature is formed by printing latent images together with visually integrated settings using an invisible ink. Even if illuminated by a wavelength capable of rendering the inks visible, the latent images remain visually indistinguishable from their visually integrated settings. However, the latent images and visually integrated settings differ in one or more less obvious ways so that the latent images can be distinguished by using a visual aid.
In one embodiment, apparatus for integrating a quantity of light is provided with a photosensor, an integration capacitor, and a transfer amplifier. The transfer amplifier has i) an input coupled to receive a voltage determined by the integration capacitor, and ii) an output.

Other embodiments are also disclosed.

Method and apparatus for mixing light emitted by a plurality of solid-state light emitters
In one embodiment, light emitted by a plurality of solid-state light emitters is mixed by mounting the plurality of solid-state light emitters on a transparent to translucent substrate so that they primarily emit light away from the substrate. The light emitters are then covered with a transparent to translucent encapsulant; and the encapsulant is coated with a reflective material that reflects light emitted by the light emitters toward the substrate. Related apparatus is also disclosed.
A light emitting device having a die that includes a light source that generates light of a first wavelength and a layer of phosphor particles covering the die is disclosed. The phosphor particles convert a portion of the light of the first wavelength to light of a second wavelength. The light source can be fabricated by attaching the light source to a substrate, and converting the light source by applying a light converting layer that includes a volatile carrier material and particles of a phosphor that convert light of the first wavelength to light of the second wavelength over the light source. The volatile carrier material is then caused to evaporate leaving a layer of the phosphor particles over the light source. A binder material can be incorporated in the volatile carrier for binding the phosphor particles to one another after the volatile carrier material is evaporated.
A technique for controlling a Light Emitting Diode (LED) based light system involves driving individual light sources that make up the LED-based light system at non-overlapping intervals so that light source-specific feedback signals can be generated in response to the emitted light. The light source-specific feedback signals are then used to individually adjust the light sources to achieve desired luminance and chrominance characteristics of the emitted light.
