摘要： The innovation relates to systems and/or methodologies for error detection during sub-assembly in high voltage analog circuits. A signal driver communicates test signals to one or more high voltage analog circuits, and a state machine compares the electrical and/or thermal responses of the high voltage analog circuits to a set of predetermined expected results (e.g., signatures). The signal driver and state machine can be incorporated into the high voltage analog circuits. The expected results can be stored in the target circuits in the form of look-up tables, matrices, and so forth. Errors, such as, dry solders and bridge solders can be determined based on the comparison of the obtained responses to the expected signatures.

摘要： The present invention relates to circuits and methods for limiting the operating area of a transistor in a constant current source. The circuits and methods use a detector and a driver to limit the operating area of a transistor. The detector and driver have parameters selected so that, when the voltage at the drain of the transistor satisfies a reference condition, the driver causes drain current of the transistor to decrease. The reference condition is determined relative to the maximum safe drain-to-source voltage at the design drain current of the constant current source.

摘要： The present invention relates to circuits and methods for controlling one or more LED strings. The circuit comprises a programmable controller coupled to one or more detectors, wherein the one or more detectors are configured to detect one or more measurable parameters of one or more LEDs or LED drivers. The controller is configured to receive information from the one or more detectors related to the one or more measurable parameters and use that information to determine the desired drive voltage for the LED strings. The controller is associated with a power supply having power factor correction (PFC) capability. The controller provides the power supply with a control signal indicative of the desired drive voltage for one or more LED strings. The power supply also receives ac voltage and current waveforms as inputs and performs power factor correction and rectified waveforms related to the ac waveforms. The power supply generates the desired drive voltage based on the control signal.

摘要： The present invention involves an electrical system in which an analog signal channel passes through various integrated circuit chips (ICs). The channel can carry one or more analog signals. Each IC can modify the signal(s) passing through it and pass it on to another IC or system component. The channel can be programmable. Each IC can include a comparator or a multiplexor to receive the channel signal from another IC or system component and to modify the received signal before transmitting it to another IC or system component. The comparator or the multiplexor can be programmable and can be selectively configured to compare the incoming signal from the channel with a variety of other signals and thresholds, or to simply act as a flow through gate and allow the signal to pass without any modification. The comparison can determine the output of the comparator. The operation and programming of the comparators, the multiplexors and the channel can be centrally controlled by a system controller, can be independently controlled by the ICs, or a combination thereof.

摘要： Integrated backlight unit (BLU) and liquid crystal systems and circuits in liquid crystal display (LCD) systems are described. An LCD system can include a BLU to emit light at different intensities, and a BLU controller coupled to the BLU and configured to control the intensities. An LCD unit can receive the emitted light, and emanate light at a selected luminosity. The LCD unit can include pixels corresponding to: a liquid crystalline medium to provide a transmittance of the light emitted or to transmit a color light; and transistors adapted to modulate reference voltages. An LCD unit controller can be coupled to the LCD unit and configured to control luminosity of the light emanated from the LCD unit. The BLU and the LCD unit, which can be integrated in a single integrated circuit, can be controlled during concurrent time periods for contrast enhancement of images displayed from the LCD unit.
