  • Publication number: 20190180660
    Abstract: A passively and nonintrusively monitoring liquid crystal display (LCD) system includes a graphics controller configured to generate alternating sets of drive instructions and forward the drive instructions for execution by drive electronics to activate display elements of a display surface. An initial set of drive instructions corresponding to a first frame causes the drive electronics to draw an initial pattern such as a solid red fill to selected regions of the display surface. An alternating set of drive instructions causes the drive electronics to draw a contrasting pattern such as a solid cyan fill to the selected regions. Given a sufficiently high refresh rate between the initial and alternating sets, a human operator perceives only the integration of the two patterns unless the display system is in a stuck or frozen state, when the frozen initial and contrasting patterns clearly and quickly indicate the stuck/frozen failure condition.

  • Patent number: 9846509
    Abstract: Alternating touchscreen conductors in each layer of a touchscreen display are connected to separate touchscreen controllers. Each controller completely and separately resolves a location anywhere on the display so that a failure of either controller, or the failure of conductors connected to either controller, do not degrade touchscreen usability. Conductors in separate layers, connected to separate controllers may be isolated via insulators to prevent undesirable shorts. Conductors are shaped to minimize the area covered by insulators and maximize the area of useful conductor overlap.

  • Patent number: 8089579
    Abstract: The present invention is a display assembly including: a display, a backlight module and a plurality of grills. The backlight module generates light rays for illuminating the display. The generated light rays exit the backlight module and are directed to a set of grills (ex.—Black Matrix substrates), which are configured between the backlight module and the display. The grills are configured for allowing a first portion of the light rays (ex.—light rays directed toward an eye position of a viewer of the display) to pass through the grills to the display, but are also configured for blocking a second portion of the light rays (ex.—light rays directed away from the viewer), thus preventing the second portion of light rays from reaching the display. The first portion of light rays are then received by and emitted from the display towards the eye position of the viewer.

  • Patent number: 7499011
    Abstract: A method of improving response time of a display element in a display is disclosed. According to the method, a command input is provided that represents a desired response of the display element. The command input is modified, using a compensation function, to produce a command output to be sent to the display element. The compensation function uses the command input and a modeled luminance of the display element in a present state and at least one previous state to compute the command output. The command output is transmitted to the display element.

  • Patent number: 7002546
    Abstract: A variably controlled LCD backlight is disclosed. The backlight includes a first light source that emits light within a first spectral power distribution and has a first radiant power output. A second light source emits light within a second spectral power distribution and has a second radiant power output. A detector detects the first and second radiant power outputs. A processor is connected to the detector and calculates chromaticity and luminance values of the emitted light based on the first and second radiant power outputs. The processor compares the calculated chromaticity and luminance values with desired chromaticity and luminance values, respectively. A controller is operationally connected to the processor and adjusts one or more of the first radiant power output and the second radiant power output in response to a difference between the calculated chromaticity and luminance values and the desired chromaticity and luminance values.

  • Patent number: 6970151
    Abstract: A display system is provided that reduces electromagnetic emissions of at least one frequency component of a signal in the display system. A signal that drives a display is modulated so that one or more frequency components of the driving signal are attenuated due to the modulation of the signal. In one embodiment, an LCD controller is adapted to provide a modulated row driving signal to an active matrix LCD. The input data source may be adapted to accommodate the modulated display driving signal. Alternatively, a FIFO buffer is used to buffer input data to accommodate the modulated display driving signal. In a further embodiment, a clock modulating circuit is provided to modulate the display driving signal without modifying the display controller.

  • Patent number: 6353425
    Abstract: The column driver for a liquid crystal display (LCD) provides separate analog signals to each color element associated with the pixel. For example, a separate analog signal is provided to a red element, a blue element, and a green element. The driver circuit receives a digital signal representative of the gray scale voltage and provides the analog signal through a switch matrix to each color element. The driver circuit reduces undesirable color shifts as gray scale values are varied.

  • Patent number: 5959604
    Abstract: A method and apparatus for monitoring the performance of a liquid-crystal display driver is described. The monitoring apparatus includes an analog feedback stage comprising an array of analog switches including a single switch for each output of the display driver wherein the output of each switch is connected to a single feedback line. A control circuit selectably actuates any of the switches such that the corresponding display driver output line is connected to the feedback line. The signal at any selected display driver output line may be monitored to ensure proper functioning thereof. The performance of the display drivers and supporting circuitry may be thereby monitored.
