20080239158 | ADAPTIVE GAMMA VOLTAGE SWITCHING METHOD AND DEVICE USING THE SAME - An adaptive Gamma voltage switching method and a device using the same is presented. An equalization unit utilizes a video data to obtain an equalized luminance data. An adaptive Gamma voltage switching core dynamically adjusts a Gamma voltage and outputs the adjusted Gamma voltage to a panel according to the equalized luminance data so as to enable the panel to alternately display a black insertion frame and a dynamic frame with adaptive contrast. The present invention not only enhances frame contrast but also reduces frame blur, and furthermore improves the insufficient luminance caused by black insertion. | 10-02-2008 |
20080252625 | DISPLAY METHOD WITH INTERLACING REVERSAL SCAN AND DEVICE THEREOF - A display method with interlacing reversal scan and a device thereof are provided. The scan mode is interlacing reversal scan. Thus, in time and space, each color frame with poor luminance response can be alternately distributed on up-side and the down-side region of the frame instead on low-side region of the frame. Then, during the period of continuous frame displaying, the present invention may balance color distribution between the up-side and the down-side region, and effectively reduce the flicker phenomenon of the frame. | 10-16-2008 |
