  • Patent number: 11940737
    Abstract: A method includes receiving a device design layout and a scribe line design layout surrounding the device design layout. The device design layout and the scribe line design layout are rotated in different directions. An optical proximity correction (OPC) process is performed on the rotated device design layout and the rotated scribe line design layout. A reticle includes the device design layout and the scribe line design layout is formed after performing the OPC process.

  • Patent number: 11922855
    Abstract: An information handling system includes a host processing system and a Liquid Crystal Display device. The host processing system includes a graphics processing unit (GPU) and the LCD device includes a memory device and a DisplayPort Configuration Data (DPCD) register. The host processing system 1) determines whether the first GPU supports a Dynamic Display Shifting (DDS) mode, 2) when the GPU does not support the DDS mode, provides a first indication to the LCD device that the GPU does not support the DDS mode, and 3) when the GPU supports the DDS mode, provides a second indication to the LCD device that the GPU supports the DDS mode. The LCD device retrieves a Panel Self Refresh (PSR) setting from the memory device and stores the PSR setting to the DPCD register in response to the first indication, and retrieves a DDS setting from the memory and stores the DDS setting to the DPCD register in response to the second indication.
