  • Publication number: 20040246224
    Abstract: A liquid crystal display (LCD) driving apparatus and the method thereof is disclosed. The method receives a pixel and drives a pixel of the LCD according to the pixel value During a frame period, wherein the frame period is divided into a precharge field and a compensation field. Firstly, a precharge pixel value is decided according to the pixel and a reference value. A compensation pixel value is decided according to the precharge pixel. Next, a precharge driving voltage is determined according to the precharge pixel value. Afterwards, a compensation driving voltage is determined according to the compensation pixel value. Finally, the pixel is driven according to the precharge driving voltage and the compensation driving voltage respectively during the precharge field and the compensation field.

  • Patent number: 6756742
    Abstract: A driving method for a flat panel display. First, an image signal is transformed to frame data. Next, characteristic data for the frame data is obtained. Next, a scanning order of the first electrodes is determining according to the characteristic data. Next, scanning electrodes are driven in the scanning order during the addressing period. Finally, the data electrodes corresponding to the first electrodes are driven to perform the addressing operation.

  • Publication number: 20030206186
    Abstract: A driving method for PDPs with variable vertical frequency. The method increases the sum of the sustain periods to obtain high brightness, by adjusting vertical frequency of a PDP through an image loading such that each image frame time displayed on the PDP is adjusted. The inventive driving method also adjusts total sustain pulses in the PDP through the image loading. To comply with the driving method, a driving apparatus is further provided to achieve the high brightness.
