A plurality of infrared-light-emitting areas are displayed in a display screen of a liquid crystal display apparatus in a method that allows each of the infrared-light-emitting areas to be distinguished. A user’s preferred device settings andor functions may be provisioned automatically. The control system includes a control module that defines a plurality of sub-time constraints between each two operations, generates a plurality of equations according to the time constraints and the sub-time constraints, and calculates the sub-time constraints using the equations. Each of these orthogonal components is then output into a separate PM or single mode fiber. Each of the sidewalls is bent inwardly to form a bent portion with a groove formed between the bent portion and an adjacent sidewall for providing extra access to airflow through the passage. The method further includes generating a second set of colors for the second set of rasterization results without the pixel shader unit performing any processing operations on the second set of rasterization results.
