METHOD FOR OPTIMIZING BRIGHTNESS IN DISPLAY DEVICE AND APPARATUS FOR IMPLEMENTING METHOD, ESPECIALLY USING THE PRINCIPLE OF DUTY CYCLE MODULATION |
摘要 |
PURPOSE: A method for optimizing brightness in a display device and an apparatus therefor are provided to improve a picture quality of pictures displayed on all kind of displays based on a principle of duty cycle modulation of a light emission, and to reduce EMI(Electro-Magnetic Interference) problems. CONSTITUTION: An apparatus for implementing a method for optimizing brightness in a splay device includes at least one average picture power measuring circuit(11), a sub field coding circuit(13), and a power level control unit(12) storing a table of a power level mode. The apparatus includes a counter for counting actual numbers of sustain pulses, and a comparator for comparing the actual numbers with a threshold value and for changing the length of the sustain pulse in accordance with a progression function used.
