    摘要: A system and method for controlling subsections of an LED backlight for a liquid crystal display (LCD). Exemplary embodiments analyze the histograms for each subsection of the LCD which corresponds with the subsections of the LED backlight in order to produce a proper luminance for the backlight subsection. The proper luminance may be less than the maximum or typical luminance that is produced by common LED backlights. By reducing the luminance the resulting display can have less power consumption, longer lifetime, and higher contrast ratios. The original subpixel voltages for the LCD are re-scaled based on the proper luminance for the backlight subsection. Virtual backlight data may be created to simulate the luminance at each subpixel and the virtual backlight data may be used to re-scale the original subpixel voltages. The virtual backlight data may be used to blend between adjacent subsections of the LED backlight which may be producing different levels of luminance.

    摘要: A system and method for displaying images or video on an electronic display. A unique identifier may be embedded within the frames of images or video and detected by a light sensor. The data from the light sensor is analyzed to determine if the proper image or video was actually shown at the display. Some embodiments analyze the data from the light sensor in real time and may stop displaying the image or video if the data is not in the format of a unique identifier. Using this embodiment, the system can prevent unintended images or video from being shown on the display.

    摘要: A removable video module for a backlit liquid crystal display (LCD) contained within a chassis and having a timing and control board (TCON) with a board edge connector and an access opening in the chassis. The module preferably having a video input connection and means for generating a Low Voltage Differential Signaling (LVDS) video. The video module also preferably has a board edge connector adapted to connect with the board edge connector on the TCON, where the video module is adapted to fit through the access opening to connect with the TCON. Other embodiments may utilize a backplane where the video module and a power module are adapted to connect with the backplane and electrically communicate with the rest of the display. Outputs for either the video signal, power supply, or both may be provided so that a plurality of displays may be daisy-chained together.

    摘要: A system and method for allocating power to a plurality of displays is disclosed. An exemplary system preferably includes an AC current sensor, a power load sharing controller, ambient light sensors for each display, and a brightness controller for each display. A maximum total current draw may be selected. The ambient light contacting each display may be measured and a corresponding desired brightness calculated. Depending on the present amount of current draw, the system determines if the displays can be driven at the desired brightness without exceeding the maximum total current draw. If yes, the displays are driven at their desired brightness. If no, the desired brightness for each display may be slightly reduced to prevent exceeding the maximum total current draw. Thus, as the ambient light varies between the displays, the available power may be shared.
