Abstract: A system and method for compensating for non-uniform illumination from a light guide for a display in an electronics device is provided. The system comprises: a memory device storing a data representing a first compensation pattern for generation on the display to block light from a first portion of the light guide relative to light from a second portion of the light guide; a first module to incorporate the stored representation into an image to be displayed on the display; and a second module to generate the image with the stored representation for display on the display. In the system, when the first module generates the first compensation pattern on the display, the first compensation pattern aligns with the first and second portions to reduce an intensity of light from a light source passing through the first compensation pattern from the first portion relative to an intensity of light passing through the first compensation pattern from the second portion from the light source.

Abstract: Disclosed is a digital type anti-glare device capable of conveniently performing input, operation and adjustment, and a method of controlling the same. The digital type anti-glare device includes a touch sensor input unit recognizing a shade degree and a grind mode level by direct selective operation or adjustment of a user as a digital contact signal and inputting the shade degree and the grind model level to the control unit, and an encoder switch input unit recognizing a sensitivity level and an opening delay level by the selective operation or adjustment of the user and inputting the sensitivity level and the opening delay level to the control unit. Accordingly, it is possible to prevent operation failure due to switch contact, dust or humidity or the like by a touch sensor and encoder input and to facilitate input, operation and adjustment even in a state in which an operator wears gloves.

Abstract: A vehicle rearview mirror system includes a transflective reflective element, an ambient light sensor that senses ambient light and a glare light sensor that senses glare light. A control circuit establishes a reflectance level of the reflective element, and the control circuit is responsive to light detection by at least one of the ambient light sensor and the glare light sensor. A display element is disposed behind the reflective element and operable to display information through the reflective element and viewable through the mirror reflector of the reflective element by a driver of the vehicle when the display element displays information, and substantially non-viewable by the driver of the vehicle when the display element does not display information. A display intensity control adjusts display intensity responsive to a light detection by at least one of the glare light sensor and the ambient light sensor.

Abstract: There are provided systems and methods for automatic adjustment of sensitivity threshold settings in an auto-darkening lens. For example, a user may initiate an automatic sensitivity setting process by activating a user interface (e.g., a button, a switch, a slider, etc.). The automatic sensitivity setting process may proceed to gradually increase the sensitivity threshold voltage until it exceeds an optical voltage based on the ambient light. The process may then be terminated. In some embodiments, a hysteresis may be added to the sensitivity threshold voltage to prevent lens flicker. The automatic sensitivity setting process may be implemented in a digital or analog system. These automatic sensitivity setting processes and systems may save time and provide for more precise sensitivity adjustment.
