Abstract:
The examples relate to various implementations of a software configurable lighting device, installed as a panel, that offers the capability to appear like and emulate a variety of different lighting devices. Emulation includes the appearance of the lighting device as installed in the wall or ceiling, possibly, both when lighting and when not lighting, as well as light output distribution, e.g. direction and/or beam shape.
Abstract:
In described examples, an LED backlight controller (300) combines global/hybrid and local brightness/dimming control for an LED backlight illuminator with local regions illuminated by associated LED strings. Global/hybrid brightness/dimming control (302, 304) performs hybrid digital modulation control (310, 326, 328) for a predefined lower range of brightness levels, with string current maintained at a substantially constant level associated with a predefined maximum brightness for the lower range (controlling brightness by adjusting digital modulation, such as PWM duty cycle, up to a maximum), and performs hybrid string current control (314) for a predefined higher range of brightness levels (controlling brightness by adjusting string current). Local dimming control (318) is performed by introducing a local digital modulation signal (320) into a hybrid digital modulation control path (326, 328) for the associated string, so that digital modulation for the associated string is a combination of local digital modulation and global/hybrid digital modulation (326, 328, 324).
Abstract:
A display may receive image data to be displayed for a user of an electronic device. Display driver circuitry in the display may analyze the data to detect static data. The image data may contain static frames of data or static portions of a frame of data. In response to detection of static data, the display driver circuitry can take actions to avoid display damage due to burn-in effects. The display driver circuitry may reduce a peak luminance value associated with a peak luminance control algorithm, may reduce display brightness, may map image data to reduced brightness levels, or may take other actions to ensure that display pixels in the display are not damaged. Temperature information may be used in determining how to classify information as static data and in determining how significantly to reduce display pixel drive currents in response to the detection of static image data.
Abstract:
An apparatus, computing device, and a computer readable medium are described herein. The apparatus includes logic to process pixels using content adaptive LCD backlight control. The apparatus also includes logic to perform analog current level control dimming when processing the pixels, and logic to linearly compensate for the analog current level control dimming when processing the pixels.
Abstract:
A scanning laser projector (100) includes a scanning mirror (162) that moves in a sinusoidal motion on at least one axis. Pixels are displayed by modulating a laser beam that is reflected by the scanning mirror. Pixels are generated using light pulses of different duty cycles based on the position and/or angular velocity of the laser beam.
Abstract:
Described is an interactive control device (1) for at least one service apparatus (2), comprising a control unit (3), a screen (4) operatively connected to the control unit (3) having touch selection means (5) for interacting with the user. The touch selection means (5) are configurable between an active condition wherein they receive the touch information of the user and an inactive condition wherein they do not receive the touch information of the user. More specifically, the interactive control device (1) comprises a presence and distance sensor (7) operatively connected to the control unit (3) and configured for generating a detection signal (8) representing the presence and the distance of a user relative to the sensor (7). The control unit (3) is configured for receiving the detection signal (8), for processing it and for generating a control signal of at least part of the service apparatus (2) as a function of the processing.
