摘要： A backlight module detecting abnormal lamp tubes and an LCD employing such a backlight module are proposed. The LCD includes a voltage calculator for detecting voltage applied on ends of a lamp tube to monitor the lamp tube. Once the lamp tube becomes abnormal, the voltage varies accordingly. The voltage calculator calculates a voltage signal from a plurality of lamp tubes and produces a voltage value. A protection circuit regards the voltage value as a feedback signal to decide if there are any abnormalities. Once any of the lamp tubes is abnormal, the protection circuit transmits the voltage signal to a pulse-width modulated integrated circuit (PWM IC) to activate a protective function. The protection circuit of the present invention obtains the protection signal by sampling the voltage signal of the ends of the lamp tube and then gets the control signal by means of the calculation of the voltage calculator. Thus, voltage level retrieved from the protection signal are less easily affected by dimming and temperature.

摘要： The present invention discloses a backlight module with a related liquid crystal display (LCD) which activates light emitting diodes (LEDs) by utilizing an alternate control method. The present invention utilizes two inverters to individually activate two sets of LEDs through an alternate method. During the same switching cycle period, the two sets of LEDs take turns turning on/off; that is, the two set of LEDs are in a closed state in a duty cycle of 50 percent. Since each set of the LEDs are in a closed condition in half the time during a switching cycle period, both of excess temperature produced by all of the LEDs when lightened simultaneously and thermal power generated during the lighting of the LEDs can be effectively reduced.

摘要： A signal may be arbitrarily delayed in discrete steps by an arbitrary delay buffer having an analog delay and a digital delay. An analog delay may have a number of selectable delay stages (e.g. ring oscillator with VCDL stages). A digital delay may have rising and falling edge detectors, resettable ring oscillators that oscillate in response to rising or falling edges and counters to count oscillations and generate rising and falling edge delay signals when oscillation counts reach rising and falling edge delay counts. A resettable ring oscillator may have a resettable stage (e.g. VCDL) that may be enabled and disabled. Selection of one or both digital and analog delays and respective delay times may be based on one or more characteristics. For example, an analog delay may delay an input signal or a delayed input signal received from the digital delay based on input signal frequency or total delay.
