    Abstract: A controller for controlling dimming of a light-emitting diode (LED) light source includes a switch monitoring pin, a current monitoring pin, and a control pin. The switch monitoring pin monitors an operation of a power switch which transfers an AC voltage to a rectifier when the power switch is on. The current monitoring pin receives a current monitoring signal indicating a current flowing through the LED light source. The control pin generates a control signal to control a second switch coupled in series with the LED light source to adjust the brightness of the LED light source according to the operation of the power switch.

    Abstract: A method for producing a light reflecting structure in a transflective or reflective liquid crystal display uses one or two masks for masking a photoresist layer in a back-side exposing process. The pattern on the masks is designed to produce rod-like structures or crevices and holes on exposed and developed photoresist layer. After the exposed photoresist is developed, a heat treatment process or a UV curing process is used to soften the photoresist layer so that the reshaped surface is more or less contiguous but uneven. A reflective coating is then deposited on the uneven surface. One or more intermediate layers can be made between the masks, between the lower mask and the substrate, and between the upper masks and the photoresist layers. The masks and the intermediate layers can be made in conjunction with the fabrication of the liquid crystal display panel.

    Abstract: A backlight controller for driving multiple light emitting diode (LED) strings includes feedback circuitry, phase array circuitry, and encoder circuitry. The feedback circuitry generates multiple feedback signals indicative of currents flowing through the LED strings respectively. The encoder circuitry generates a code signal indicative of a total number of operative LED strings among the multiple LED strings based on the feedback signals. The phase array circuitry generates multiple saw tooth signals according to the code signal. A phase shift amount between two adjacent signals of the saw tooth signals is determined by the total number of the operative LED strings. The phase array circuitry compares each of the saw tooth signals with a dimming control signal to generate multiple phase shift signals so as to respectively control the operative LED strings.
