EIZO Corporation, Hakusa...

1. An LED control circuit comprising an LED voltage generating unit, an LED voltage control unit, an LED current control unit, and a storage unit whereinthe LED voltage generating unit is configured to apply a voltage to an LED based on an LED voltage command value input from the LED voltage control unit,
the LED voltage control unit is configured to determine the LED voltage command value based on a cathode potential of the LED,
the LED current control unit is configured to control a value of current flowing through the LED based on the LED voltage command value,
the storage unit is configured to store a look-up table in which a correspondence relationship between luminance and the LED voltage command value is predetermined, and
the LED current control unit controls the value of current based on a desired luminance, the LED voltage command value in the lookup table corresponding to the desired luminance, and an actual LED voltage command value.

MANAGEMENT OF MULTIPLE DISPLAY AREAS

EIZO Corporation, Ishika...

1. A display control method for displaying image data on a display screen of a display device by an image generation device's outputting the image data to the display screen, the display control method comprising:displaying, on the display screen of the display device, a first display area and displaying a pointer on the first display area;
a first step of determining that a pointer position has moved from a first working area to a second working area by the image generation device;
in response to determining the pointer position has moved from the first working area to the second working area,
outputting a first command by the image generation device to a PinP circuit, the first command causing the PinP circuit to superimpose a second display area on the first display area, and
displaying, on the display screen, the first display area as well as the second display area superimposed on the first display area, wherein entire area of the second display area is displayed inside the first display area;
a second step of determining that the pointer position has moved from the second working area to the first working area by the image generation device;
in response to determining the pointer position has moved from the second working area to the first working area,
outputting a second command by the image generation device to the PinP circuit, the second command causing the PinP circuit to hide the second display area, and
hiding, on the display screen, the second display area displayed inside the first display area; and
keeping a display condition that the entire area of the second display area is displayed inside the first display area, until determining that the pointer position has moved from the second working area to the first working area,
wherein
the pointer position, the first working area and the second working area are generated in a memory stored in an image generation device, and are not displayed on the display screen,
the pointer position is defined on the first and second working area,
each coordinate of the pointer position in the first working area is mapped onto each displayed position of the pointer in the first display area,
each coordinate of the pointer position in the second working area is mapped onto each displayed position of the pointer in the second display area, and
in the first step, the second display area onto which the second working area is mapped is not displayed on the display screen,
wherein the PinP circuit is embedded in the display device.
