摘要:
A device for aligning a LCD panel having circuit elements with driver circuit card assemblies, consisting of retractable pins located around a central platform. The retractable pins extend in order to receive the LCD panel and circuit element assembly and hold it in place as the circuit elements are aligned with driver circuit card assemblies. Once aligned, the drivers and LCD panel can be bonded together. Once bonded, the pins are retracted and the LCD panel and driver assembly is released. The present invention also relates to a method of aligning LCD panels and drivers using retractable pin tools.
摘要:
A flat panel display, particularly a liquid crystal display has a front plate with a plate area defined by a plate perimeter, which is in turn defined by a first and second pair of parallel sides, the pairs of sides in perpendicular relationship to each other. An active display area providing a unitary visual display is located within the plate perimeter. In the invention, this active display area is divided into at least first and second display areas, a visual output of said first and second display areas being separately driven. In some embodiments, one or both of the display areas is subdivided into first and second subdisplay areas, with the visual output of the first and second subdisplay areas being separately driven.

摘要:
A touch panel is integrated into a flat panel display device having a visual display surface with a front polarizer layer, particularly a liquid crystal display device. The touch panel comprises a flexible transparent membrane containing the front polarizer layer and having a first transparent conductive layer on a lower surface of the flexible transparent membrane and a rigid base comprising the flat panel display device and having a second transparent conductive layer on an upper surface of the rigid base. At least one spacer separates the flexible transparent membrane from the rigid base, keeping the first and second transparent conductive layers in spaced-apart facing relationship. A bus bar and tail communicate a signal from the touch panel to the flat panel display device.

A flat panel display having a black mask EMI layer isolated from Vcom and tied to zero potential. The flat panel display has an integral metal heater layer and thermal sensor that are in close proximity to the liquid crystals to provide efficient heating and temperature sensing.
摘要:
A method and system for automatically testing visual displays and automatically optimizing the voltage settings for each visual display being tested by harmonizing and tailoring the voltage settings applied to the display and automatically setting into memory the coefficients to achieve the optimized voltage levels for each visual display.
摘要:
A system for detecting errors in a source driver for an electronic display includes an upstream logic device, a comparator, and a source driver. The source driver has a number of driven channels which transmit active signals for generating an image on the electronic display and one or more dummy channels which transmit dummy signals to the comparator. The comparator receives and compares signals from at least some of the driven channels with the dummy channels and generates an alert for transmission to the upstream logic device if a mismatch is detected.
摘要:
A backlight device for a liquid crystal display containing a substantially planar light guide with a light emission surface and a light-collecting portion opposing the light emission surface. A pair of opposing side portions may define the periphery of the light guide. A first plurality of LEDs are placed so as to direct the emitted light into the light-collecting portion. An NVIS filter is preferably placed adjacent to at least one of the side portions. A second plurality of LEDs are placed to direct the emitted light through the NVIS filter and into a side portion of the light guide. Alternative embodiments can contain NVIS filters and LEDs along additional edge portions of the light guide. Some embodiments may use directing elements or slanted surfaces of the light guide to direct the light from the second plurality of LEDs into the edge portions of the light guide.
摘要:
In an exemplary embodiment, each horizontal and vertical conductor of a TFT array may be in electrical contact with a first and second control system. Initially, the entire display is driven by the first control system. When/if a failure occurs in the first control system, it is powered down and the second control system maintains operation of the entire display. Each control system may contain a set of source/gate drivers, display interface board, and power supply. A reversionary button may allow the user to manually switch between control systems. Alternatively, failure may be detected by the display interface boards or a graphics processor.
摘要:
A flat panel liquid crystal display has a front plate and a rear plate with a layer of liquid crystal material maintained in a cavity between them. A thin film transistor array layer is disposed in the cavity, as is an integral heater with a grid of intersecting sets of horizontal and vertical conductors. The heating capacity of the heater is predeterminably set by selectively interrupting continuity of at least some of the intersecting conductors. In some embodiments, the discontinuities occur in only one set of the intersecting conductors.
