Abstract: Disclosed are example techniques for frame-based power management in a light emitting diode (LED) system having a plurality of LED strings. A voltage source provides an output voltage to drive the LED strings. An LED driver generates a frame timing reference representative of the frame rate or display timing of a series of image frames to be displayed via the LED system. An update reference is generated from the frame timing reference. The LED driver monitors one or more operating parameters of the LED system. In response to update triggers marked by the update reference, the LED driver adjusts the output voltage of the voltage source based on the status of each of the one or more monitored operating parameters (either from the previous update period or determined in response to the update trigger), thereby synchronizing the updating of the output voltage to the frame rate (or a virtual approximation of the frame rate) of the video being displayed.

Abstract: Techniques for dynamic headroom control in a light emitting diode (LED) system are disclosed. An output voltage is provided to drive a plurality of LED strings. A feedback controller monitors the tail voltages of the LED strings to identify the minimum tail voltage and adjusts the output voltage based on the lowest tail voltage. The LED strings grouped into subsets and the feedback controller is segmented such that, for a certain duration, a minimum tail voltage is determined for each subset. The minimum tail voltages of the subsets are used to determine the overall minimum tail voltage of the plurality of LED strings for the certain duration so as to control the output voltage in the following duration. The segments of the feedback controller can be implemented in separate integrated circuit (IC) packages, thereby facilitating adaptation to different numbers of LED strings by integrating the corresponding number of IC packages.

Abstract: A peak detection/digitization circuit includes a plurality of level detect units, each having a comparator and a flip-flop with a clock input responsive to the output of the comparator. For a detection period, each level detect unit configures a data output signal of the flip-flop to a first data state responsive to a start of the detection period. Further, each level detect unit is configured to enable the comparator responsive to the data output signal having the first data state or a second data state, respectively. While the comparator is enabled during the detection period, the level detect unit configures the data output signal of the flip-flop responsive to a comparison of an input signal to a corresponding reference voltage level by the comparator. The data output signals of the flip-flops of the level detect units at the end of the detection period are used to determine a digital value representative of a peak voltage level of the input signal.

Abstract: A pulse width modulation (PWM) signal generator generates a PWM signal having a specified effective PWM duty resolution for a corresponding cycle window. The PWM signal generator receives an N-bit value representing a duty to be implemented and sets values X and Y to the M least significant bits and the N-M most significant bits, respectively, of the N-bit value. The value M can be determined based on the value N and a maximum implementable frequency of a clock signal used to time the generation of each PWM cycle. The PWM signal generator generates a cycle window of 2M PWM cycles, each PWM cycle of the cycle window having a duty of either Y or Y+1. The number of PWM cycles in the cycle window having the duty Y+1 is based on the value X and the PWM cycles having a particular duty are contiguous within the cycle window.

Abstract: A power management technique in a light emitting diode (LED) system is disclosed. The LED system includes a plurality of LED driver connected in series, each LED driver configured to regulate the current flowing through a corresponding subset of a plurality of LED strings. Each LED driver determines the minimum tail voltage of the LED strings of the corresponding subset, compares the determined minimum tail voltage with an indicator of a minimum tail voltage of one or more other subsets provided from an upstream LED driver in the series, and then provides an indicator of the lower of the two tail voltages to the downstream LED driver. In this manner an indicator of the minimum tail voltage of the plurality of LED strings is cascaded through the series. A feedback controller monitors the minimum tail voltage represented by the cascaded indicator and accordingly adjusts an output voltage provided to the head ends of the plurality of LED strings.

Abstract: A rework method of a metal hard mask layer is provided. First, a material layer is provided. A dielectric layer, a first metal hard mask layer, and a patterned first dielectric hard mask layer have been sequentially formed on the material layer. There is a defect on a region of the first metal hard mask layer, and therefore the region of the first metal hard mask layer is not able to be patterned. After that, the patterned first dielectric hard mask layer and the first metal hard mask layer are removed. A planarization process is then performed on the dielectric layer. Next, a second metal hard mask layer and a second dielectric hard mask layer are sequentially formed on the dielectric layer.
