摘要： A three-phase rectification module, the system thereof and harmonic suppression method are provided. The module includes a LCL filter unit, a three-phase uni-directional rectification unit coupled to the LCL filter unit, and a rectifier control unit for controlling power factor of three-phase AC power source and DC output voltage of the three-phase uni-directional rectification unit. A commutation diode is serially connected on the bridge-arm of each set of uni-directional rectification branch which is included in the three-phase uni-directional rectification unit, making it function as current uni-direction. Herein, the power factor of the three-phase AC power source is matched with the parameters of the LCL filter unit, such that the absolute value of the phase difference between AC input voltage and current of the three-phase uni-directional rectification unit is close or equal to a preset threshold.

摘要： Methods and apparatus for achieving color and luminance uniformity in color output devices. In one embodiment, measurements of luminance and chrominance are taken at various regions of the display surface for a range of color inputs. Using the collected data, a color volume is formed for each of the measured regions. This color volume comprises a set of all colors producible at the measured region. The color volumes for each of the measured regions are then used to generate a common color gamut, i.e., a volume of colors that are producible in each of the measured regions. A gamut mapping can then be performed for all or a portion of the positions on the display surface to a target color gamut. Input data for the gamut mapping process may be determined by conventional interpolative techniques.

摘要： Disclosed herein are liquid-crystal display (LCD) touch screens that integrate the touch sensing elements with the display circuitry. The integration may take a variety of forms. Touch sensing elements can be completely implemented within the LCD stackup but outside the not between the color filter plate and the array plate. Alternatively, some touch sensing elements can be between the color filter and array plates with other touch sensing elements not between the plates. In another alternative, all touch sensing elements can be between the color filter and array plates. The latter alternative can include both conventional and in-plane-switching (IPS) LCDs. In some forms, one or more display structures can also have a touch sensing function. Techniques for manufacturing and operating such displays, as well as various devices embodying such displays are also disclosed.
