Abstract: A direct view light emitting diode (DV LED) display (296), includes (i) one or more DV LED modules (200) each containing at least one circuit board (300) having an array of surface mount device LEDs (100) defining a display surface (304), and (ii) a protective transparent polymeric film (302, 390) covering at least a portion of the display surface. The transparent polymeric film includes a polymer material layer (400), and an adhesive layer (402) laminated to the polymer material layer and directly attached to the display surface of the DV LED module. The transparent polymeric film may facilitate the use of touch screen technology with a DV LED display, and may be removable to allow repair or disassembly/reassembly of the DV LED display.

Abstract: In one embodiment, an electronic display apparatus for installation on a display case merchandiser having a door with a transparent front panel is disclosed. The apparatus comprises a bezel, a transparent electronic image display panel, and a light source. The bezel is configured to attach to the door of the merchandiser so a portion of the transparent front panel of the door is viewable through an opening of the bezel. The display overlays at least a portion of the bezel opening and a portion of the transparent front panel of the door when the apparatus is installed. The light source fits in a gap formed between the bezel and the door when the apparatus is installed.

Abstract: An image sensor array includes image sensors having photo TFTs to generate photocurrent in response to received images. The photo TFTs each have their respective gate electrodes and source electrodes independently biased to reduce the effects of dark current. Storage capacitors are coupled to each photo TFT and discharged upon generation of a photocurrent. Each storage capacitor is coupled to a readout TFT that passes a current from the storage capacitor to a data line. The photo TFT may be disposed above the storage capacitor to increase the exposed surface area of the photo TFT.

Abstract: An electronic display panel is ruggedized by optically bonding optically transparent plates to the front and back of the display panel. Electronic devices associated with the display panel, such as drivers, may be encased in a resin or other material to provide environmental and mechanical protection for the electronic devices. An outdoor display device includes a two part housing with a weatherized electronic display panel mounted in one part and a back light mounted in the second part. The housing is easily opened at the display device location to provide access to the back light components and the back of the weatherized electronic display panel for maintenance or other purposes. Fans and air passages may be provided to circulate air through the housing to help cool the display device.
