摘要： The system for stabilizing wavelength of LED (light emitting diode) radiation in backlight module of the LCD (liquid crystal display) comprises two photodiodes, a plurality of LEDs, a microprocessor unit (MCU) and a driver circuit, wherein two photodiodes have different photo sensitivities in response different wavelengths. A target value, associated with a ration of photo sensitivities of the two photodiodes under two different wavelength radiations, is stored to the MCU as a referred value. Thus, another wavelength (or wavelength variation) of LED radiation is derived by comparing another target value with the referred value. The MCU determines a correction constant based on a colour match function of the derived wavelength, and outputs a compensation signal to compensate LED, wherein the compensation signal is equal to multiplication of the correction constant and an original light intensity compensation signal for compensating light intensity loss of the LED.

摘要： A method and a system for achieving a desired operation illumination condition for a plurality of light emitters are provided. The light emitters are divided into mutually distinctive groups. The groups of light emitters are sequentially activated while maintaining the rest of groups of the light emitters in an inactivated state. In this manner, the illumination condition of each group of light emitters are detected, so as to adjust a driving condition for the light emitters, thereby producing a light source with uniformly distributed white light spectra, and a homogeneous intensity distribution over the entire region of the light source.

摘要： A light-emitting diode (LED) driver is provided to drive an LED. The LED driver includes a clock supply to periodically output a modulation period. A brightness controller is provided to receive brightness data corresponding to the desired brightness of the LED. The brightness controller generates a pulse-width-modulated (PWM) duty pulse within the modulation period, a width of the PWM duty pulse being based on the brightness data. The LED driver also includes a detection controller to receive detection data indicating whether the LED is to be detected during the modulation period. When the detection data indicate that the LED is to be detected during the modulation period, the detection controller generates a detection pulse within the modulation period. A driver output is provided to output the PWM duty pulse and the detection pulse to the LED within the modulation period.
