Patent number: 9536463Abstract: A method to be used in a light emitting diode (LED) display provides a fault-healing capability. The method is applicable to a display having pixels made up of LEDs of four or more primary colors. For each pixel, the method receives a signal specifying a light intensity and a color to be displayed and detects if a fault exists in an LED of one or more of the primary colors. When no fault is detected, the LEDs of the pixel are driven with currents to achieve the specified light intensity and color. Otherwise, the LEDs of the pixel are driven in the primary colors that are without fault, using a combination of currents to achieve the specified light intensity and color. The combination of currents is derived by finding a position of the specified color in a chromaticity diagram and, using that position, deriving the currents to drive the LEDs in the primary colors without fault.Type: GrantFiled: August 8, 2007Date of Patent: January 3, 2017Assignee: LANDMARK SCREENS, LLCInventor: Paul O.
