| 20090317013 | Image format conversion system - An image format conversion system includes a horizontal filter to receive an image input signal with a frequency of a first clock signal in order to perform a filtering operation to thereby produce a horizontal filtering image signal; a first FIFO to temporarily store the horizontal filtering image signal; a 2D image interpolator to perform a deinterlacing, a vertical interpolation and a horizontal interpolation operations on the horizontal filtering image signal to further produce a scaled progressive image signal; a second FIFO connected to the 2D image interpolator to temporarily store the scaled progressive image signal; an interpolation clock controller to receive a second clock signal and produce multiple enable signals in order to enable the horizontal filter and the 2D image interpolator, wherein the second clock signal has a frequency independent of the frequency of the first clock signal. | 12-24-2009 |

| 20080218629 | Method and system for processing image data in LCD by integrating de-interlace and overdrive operations - A system for integrating de-interlace and overdrive operations includes a de-interlace device, a first frame scaling controller, a second frame scaling controller and an overdrive device. The de-interlace device performs a de-interlace operation on plural fields to thereby obtain plural frames. The first frame scaling controller receives a first frame among the plural frames and performs a vertical and horizontal scaling operation on the first frame to thereby produce a first display frame. The second frame scaling controller receives a second frame among the plural frames and performs a vertical and horizontal scaling operation on the second frame to thereby produce a second display frame. The overdrive device produces a driving voltage based on a difference between a pixel of the second display frame and a pixel of the first display frame corresponding to the pixel of the second display frame. | 09-11-2008 |

| 20110069014 | GLARE-RESISTANT TOUCH PANEL - A glare-resistant touch panel has a touch-sensing layer, a polarizing filter, a diffraction layer and an anti-reflection layer. The polarizing filter is mounted on the touch-sensing layer. The diffraction layer is mounted on the polarizing filter and splits lights into different polarized angles. The anti-reflection layer is mounted on the diffraction layer. With the diffraction layer, light polarized at a specific angle are split to be polarized at different angles and are allowed to partly pass through polarized sunglasses. Hence a sunglasses wearer can still see what the screen from the touch panel displays even if the sunglasses and the polarizing filter are oriented perpendicular to each other. | 03-24-2011 |
