Claim Text:
1. A display apparatus, comprising: a display panel area comprising a display area and a display control component; a plurality of peripheral components spaced from the display panel area, the display panel area configured to receive a plurality of display signals and control signals from the peripheral components, the display control component arranged to provide timing signals indicative of the control signals, the display area configured to display an image representative of the display signals in relationship to a common voltage in response to the timing signals; and one or more signal lines arranged to provide a compensation signal to the display area to compensating the common voltage, wherein the compensation signal is indicative of a processed signal of one or more of the control signals obtained in the peripheral components, wherein said one or more of the control signals are indicative of one or more clock signals, and wherein the peripheral components comprise: a timing control circuit configured to providing the control signals; a voltage level shifter configured to shift a voltage level of the control signals before providing the control signals to the display panel area; and a compensation-signal generator configured to receive one or more of the control signals from the timing control circuit and configured for processing said one or more of the control signals to form the processed signal, and wherein said one or more of the control signals are also indicative of a start signal arranged for starting a frame in the image, and a plurality of clock signals are arranged for controlling a timing of the display components, said processing comprising: high-pass filtering said one or more of the control signals for providing a plurality of high-pass filtered signals; summing said high-pass filtered signals for providing a summed signal; and adjusting an amplitude of the summed signal to form the processed signal.
