DEVICE AND METHOD FOR AUTOMATICALLY REGULATING POWER SOURCE FOR DISPLAY PANEL DRIVING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a device and method for automatically regulating a power source for a display panel driving system for automatically adjusting the voltage of the display panel driving power source, so as to maintain an optimal state of image quality by detecting the state of image quality. SOLUTION: To maintain the image quality displayed on the panel with a PDP driving power source circuit in an optimal state, the panel driving voltage is automatically regulating the panel driving voltage contributing to contrast and luminance deviation of a PDP image. This arrangement eliminates the need for manually adjusting the panel driving power source using variable resistance but simplifies the manufacturing processes, and is further capable of reducing adjusting deviation caused by manual adjustment of the power supply source by means of automatically adjusting the power source so as to automatically maintain the image quality in the optimal state.
