Abstract: A display processor integrated circuit includes a display processor portion and an on-chip programmable logic portion. The programmable logic portion can be configured to implement custom video and/or image enhancement functions. The display processor portion performs block-based motion detection. If no motion is detected for a given block of pixels, then interline gaps in the block are filled using temporal interpolation. If motion is detected, then interline gaps are filled using spatial interpolation. To maintain accuracy without unduly increasing computational complexity, a less complex high angle spatial interpolation method is employed where a low angle tilt condition is not detected. A more computationally intensive low angle spatial interpolation method can therefore be employed in low angle tilt conditions. Integrated circuit cost is reduced by employing pipelining to write parts of segment buffers at the same time that other parts are being read to perform the interpolation process.

Abstract: A method of manufacturing a TFT array panel for a LCD disclosers that the gate electrode wiring, transparent conducting electrode, and the first electrode of the storage capacity are formed while the first mask is processing. Then, the selective deposition method is used to process the growth of the first metal wiring. This, therefore, can reduce the numbers of the mask processes. Further, the metal deposition with photo-resist lift-off step is used to implement the layout of the second metal wiring for the consequent transmission lines in the manufacturing process. Finally, the process of the passivation layer deposition is used to implement associated circuits of a TFT array panel for a LCD. The TFT array panel for a LCD for manufacturing circuits can simplify the manufacturing process and reduce the cost.
