The present invention relates to a multi-frequency display system and method for providing color convergence. The system comprises a convergence circuit that is configured to receive a first set and a second set of color input signals. The first of color input signals operates at a first frequency, and the second set of color input signals operates at a second frequency. The system also comprises a controller circuit coupled to the convergence circuit, that is configured to generate a first convergence signal corresponding to the first frequency and a second convergence signal corresponding to the second frequency. The convergence circuit generates a first control signal in response to the first set of color input signals and the first convergence signal. The convergence circuit generates a second control signal based on the second set of color input signals and the second convergence signal. A set of electron guns coupled to the convergence circuit are configured to generate beams that are adjusted to provide color convergence at said first frequency and at said second frequency.

A method for storing status information prior to shutdown of a video monitor due to a failure. An indication of an operational parameter is obtained. Based on the indication, it is determined if the failure occurs warranting shutdown. If the failure occurs, status information is stored in a non-volatile memory for later retrieval during repair. A shutdown sequence is generated to disable the video monitor.

A video display monitor having a plurality of power-save modes that are automatically controlled by a computer includes a display element for emitting light of at least two colors and circuitry for controlling the period of light emission of each color to correspond to the different power-save modes. Also, a method for displaying the power-save modes of a computer video display monitor having a plurality of power saving modes that are automatically selected by the computer uses a display element capable of emitting light of at least two colors and includes the steps of detecting a power-save mode among the plurality of power-save modes and varying the period of light emission of each color to correspond to the different detected power-save modes.

The present invention relates to a multi-frequency display system and method for providing sharpness enhancement. The system comprises a sharpness enhancement circuit that is configured to receive a first and a second input video signal, where the first input video signal operates at a first frequency, and the second input video signal operates at a second frequency. The system further comprises a controller circuit coupled to the sharpness enhancement circuit, that is configured to generate a first sharpness enhancement signal corresponding to the first frequency and a second sharpness enhancement signal corresponding to the second frequency. The sharpness enhancement circuit generates a first control signal in response to the first input video signal and the first enhancement signal, and the sharpness enhancement circuit generates a second control signal based on the second input video signal and the second enhancement signal. An electron gun coupled to the sharpness enhancement circuit is configured to provide an first image having a predetermined sharpness level at the first frequency based on the first control signal. The electron gun also provides a second image having the predetermined sharpness level at the second frequency based on the second control signal.

A display device includes: a monitor and receiving set having a video signal receiving section, a display section, an image quality control section, a first control signal transceiver, and a first control section; and a control and transmission set having a television broadcast receiving section, a video signal input section, a video signal transmitting section, a second control signal transceiver, a key input section, and a second control section. The Power consumption of a first radio transmission path formed by the video signal transmitting section and the video signal receiving section is larger than that of a second radio transmission path formed by the first and second control signal transceivers. A control signal for a user interface is communicated by the first and second control signal transceivers. Only the second radio transmission path of the first and second radio transmission paths is communicable in a standby state.

The present invention discloses a method and apparatus for providing error detection capability for initialization data stored in a non-volatile memory used in a video monitor. The method comprises the steps of: (1) storing N test values in N distinct locations in the non-volatile memory; (2) reading the N stored test values from the non-volatile memory, each test value being read for K times; (3) selecting N read test values representative of the N stored test values; (4) comparing the N read test values with N corresponding check values; and (5) if the N read test values are equal to the N corresponding check values, reading the initialization data from the non-volatile memory.

摘要:
A system for processing a video signal is described. Components of the video signal, such as the horizontal sync signal, undergo time delays as the signal propagates and is processed by circuit elements. In order to properly align the components of the video signal for further processing, compensation for the different time delays is introduced.
