摘要： An overhead projector for use with a flat panel display assembly. The specialized overhead projector provides cooling for the LCD flat panel when used in an overhead projection configuration. The projector contains a rail on which the flat panel display is positioned for alignment and to provide air passage there through for cooling. A clamping mechanism is also described for securing the flat panel display to the projector. The flat panel display is a back-lit flat panel display subsystem for direct viewing as a monitor and also has overhead projection capability. The display subsystem contains a removable door assembly which provides for back-lighting for direct viewing. When the door assembly is removed, the active matrix LCD is semi-transparent and can be placed over the imaging screen of the overhead projector such that the LCD color image can be thus projected. The lamps that provide the back-lighting remain within the display subsystem when the door is removed and a unique optical coupling is provided between the lamps and a light pipe within the door. The display subsystem contains a sensor detecting door presence and simultaneously shuts off the lamps and reverses the display image upon door removal for overhead projection capability.

摘要： A light distributing removable door assembly (and elements thereof) for a back-lit flat panel display subsystem wherein the subsystem is for direct viewing as a monitor and having overhead projection capability. The removable door assembly provides for back-lighting via a light pipe for direct viewing when installed in the subassembly. When the door assembly is removed, the active matrix LCD is semi-transparent and can be placed over the imaging screen (viewing side down) of an overhead projector such that the LCD color image can be thus projected. The lamps that provide the back-lighting remain within the display subsystem when the door is removed and a unique optical coupling is provided between the lamps and a light pipe within the door. A specialized bi-directional light extraction pattern is used on a light pipe of the removable door to provide effective and uniform light distribution over the LCD image. A clamping mechanism is also described within the removable door for securing the layers used in the door assembly. The clamping mechanism allows a reduction in a size of a junction formed between the lighting units of the subsystem and the removable door assembly.

摘要： A back-lit flat panel display subsystem for direct viewing as a monitor and having overhead projection capability. The display subsystem contains a removable door assembly which provides for back-lighting when configured for direct viewing. When the door assembly is removed, the active matrix LCD is semi-transparent and can be placed over (viewing surface down) the imaging screen of an overhead projector such that the LCD color image can be thus projected. The lamps that provide the back-lighting remain within the display subsystem when the door is removed so as to not disturb the power supply lines to the lamps and a unique optical junction is provided between the lamps and a light pipe within the door. The display subsystem contains a sensor detecting door presence and simultaneously shuts off the lamps and reverses the display image (to right to left) upon door removal and turns on the lamps upon door insertion and displays the image from left to right. Within the display, a conductive (grounded) anti-reflective coating is used on the flat panel display to reduce electronic emissions. The system is also portable and can operate as a stand alone peripheral or integrated within a computer system board.

摘要： A flat panel display screen apparatus with optical junction and removable backlighting assembly. An optical junction is formed between a permanently housed light source within a display assembly and a removable light pipe when inserted into the display assembly. The optical junction is formed from a reflective film attached along the long axis of the light source and extends past a side of the light source to cover a gap between the light source and the light pipe. Another reflective strip is placed along and extends past an edge of the light pipe to bridge the gap. The reflective material is used to reflect stray light into the light pipe. The present invention also includes a display subsystem with a light pipe in a removable door, the removable door assembly adapted for insertion into and removal from the display assembly and comprising a light pipe for optically coupling with the light source for illuminating the flat panel display matrix with the back-light and wherein the light source remains secured within the display assembly upon removal of the removable door assembly so that a power supply line to the light source is not disturbed upon removal of the removable door assembly and further comprising a control circuit responsive to the sensor for turning the light source on when the control signal is at a first state and for turning the light source off when the control signal is at a second state.

摘要： The invention provides a liquid crystal, TFT display with driver lines folded around a light pipe and a digitizer. The digitizer has grid routing lines folded around a shield where the shield is connected to a shield of the computer system electronics. The display drivers and grid controller are mounted inward of an edge of the display. The glass layers surrounding the beads can have different thicknesses and composition while the liquid crystal surrounding the beads can be at a pressure less than atmospheric pressure. A surface of the display provides pen/pencil on paper feel as a digitizer pen is moved across the surface via hardness coatings and surface topography.

摘要： Brightness in the LCD is enhanced by polarization recycling using a pre-polarizing film to pre-polarize light, and a special reflector for recycling light reflected by the pre-polarizing film. In one embodiment, the pre-polarizing film comprises a layer of DBEF brightness enhancement film, and the rear reflector is made of a PTFF material. In another embodiment, the rear reflector is covered with a film comprising barium sulfate. The multiple light sources are selected such that, at any color temperature within a predetermined range, the brightness of the LCD is not reduced below a given threshold minimum (e.g., 70 percent of the maximum brightness). Another constraint for selecting the light sources is that within the predetermined color temperature range, the color temperature is held close to the black body curve of the CIE chromaticity diagram. The light sources are also selected so that their maximum brightness point is set to be near the middle of the predetermined color temperature range.

摘要： A cover assembly for use with a disk-shaped optical recording medium, having two substantially identical halves, each having an inner surface adapted to provide upon assembly with the medium an air gap adjacent an optical recordable coating on the medium. Each cover half is transparent and has substantially no birefringent characteristics on the region overlying the air gap, thus allowing light to pass unimpeded therethrough. The cover assembly is adapted to be coupled to the central hub of the optical recording medium and to have a raised annulus adjacent thereto to support the assembly and minimize contact with the transparent portion.

摘要： A method, computer-usable medium, and system for processing graphical data for display on a multi-component display is disclosed. Embodiments improve the display quality of multi-component displays by modifying graphical data to preemptively compensate for distortion caused by interstitial layers and/or display screens of the multi-component display, thereby enabling display of graphical objects from multi-component displays with improved optical characteristics. For example, where components of a multi-component display blur displayed images, graphical data used to display graphical objects may be modified to sharpen the graphical objects before display. The pre-sharpening amplifies the high frequency components of the displayed graphical objects to compensate for the dampening caused by passing the graphical objects through the components of the multi-component display.
