Abstract: A correcting method for a display apparatus is provided. For N original grayscale combinations, color performances of the display apparatus are respectively measured to generate N measurement results. A set of color blending equations are utilized for M original grayscale combinations according to the N measurement results to generate M blended results. From the N measurement results and the M blended results, P color performances respectively most approximate to P target performances are identified. The P target color performances correspond to P target grayscale combinations. The P color performances correspond to P original grayscale combinations in the (N+M) original grayscale combinations. A look-up table for correcting the display apparatus is established according to the P target grayscale combinations and the P corresponding original grayscale combinations.

Abstract: A control apparatus for controlling a three-dimensional (3D) display apparatus includes: an image processing unit to receive an image source signal and convert the image source signal to an interval signal. The interval signal is defined as a first timing interval and a second timing interval. A backlight control device, coupled to the image processing unit, receives the interval signal and generates a plurality of backlight control signals according to the interval signal. A backlight device, coupled to the backlight control device, receives the plurality of backlight control signals and provides a lighting source to a display device during the first timing interval and/or the second timing interval according to the plurality of backlight control signals.

Abstract: A circuit layout method for a printed circuit board (PCB) is provided. The method includes forming a pair of signal traces on the PCB, and disposing a ground trace between the pair of signal traces. The pair of signal traces and the ground trace are located at a same layer of the PCB, and the ground trace renders the pair of transmission traces to have predetermined impedance. An associated PCB is also provided. The PCB includes a circuit layer, and a ground layer for grounding. The circuit layer includes a pair of signal traces, and a ground grace disposed between the pair of signal traces. The circuit layer is different from the ground layer. Based on the circuit layout method and the associated PCB, an electronic apparatus not only complies with mobile high-definition link (MHL) requirements regarding impedance between signal traces but also offers reduced costs.
