Appl. No.:

12/123414

Assignee:

Samsung Electronics Co., Ltd.

International Classification:

G09G 3/36

US Classification:

345102, 345 89

Abstract:

Displays systems and methods for adjusting backlight illumination are disclosed wherein backlight illumination may be set low enough according to an error threshold amount in order to reduce backlight power consumption while maintaining a level of image quality. In one embodiment, image data is evaluated within a given frame and partitioned into histogram bins depending on the amount of backlight illumination requested or required by the image data. The histogram is traversed to provide an accumulative error measure. The error measure is compared against the error threshold and, if exceeded, the final backlight illumination may be set as a function of various illumination levels considered and possibly the first and a second threshold.

International Classification:

G09G 5/02
G09G 5/00

US Classification:

345589, 345590, 345613

Abstract:

In an image update, a display apparatus receives only a new portion () of an image for display but does not receive the remaining, unchanged portion of the image. The display apparatus performs a subpixel rendering (SPR) operation () for the new portion but does not redo the SPR for the whole image. Efficient techniques are provided to achieve good appearance at the edges between the new portion and the rest of the image. Other features are also provided.

Michael Francis HIGGINS - Cazadero CA, US

International Classification:

G09G 5/02

US Classification:

345600, 345694

Abstract:

Displays are provided with circuitry performing color correction to compensate for the displays' luminance and chrominance transfer characteristics. Some techniques are suitable for RGBW displays and for subpixel-rendered displays. Some displays include an external light source (e.g. a backlight unit in LCDs), and the color correction is coordinated with dynamic control of the light source.

Michael Francis Higgins - Cazadero CA, US

International Classification:

G09G 5/10
G09G 3/36

US Classification:

345690, 345102

Abstract:

One embodiment may employ one or more non-transitory computer-readable memories, the memories collectively storing instructions for executing a method of facilitating the display of an image. This method may comprise, in a display system comprising a display panel having pixels and a backlight having individually addressable colored light emitters configured to provide light to the pixels of the display panel, receiving image data corresponding to an image for display upon the display panel, the pixels each having a color to be displayed, so as to collectively display the image. The method also includes, for each pixel, evaluating whether the corresponding color to be displayed is out-of-gamut to the each pixel, so as to form a set of out-of-gamut pixels. A set of virtual primaries is determined, defining intensities of light emitted by the colored light emitters of the backlight during display of the image, the virtual primaries determined according to the colors of the set of out-of-gamut pixels.

International Classification:

G09G 5/10
G09G 3/36

US Classification:

345690, 345 87

Abstract:

A module processes image data to provide gray level signals to be used for displaying an image. The module may include a scale value control member for determining a first scale value. The module may further include a brightness control member for determining a controlled brightness value using a requested brightness value, a brightness control parameter, and a baseline brightness value. The module may further include a modification member for determining a modified scale value using the first scale value and the controlled brightness value. The module may further include a scaler for generating the gray level signals using the image data and at least one of the modified scale value and a damped scale value, the damped scale value being determined using the modified scale value. The module may further include hardware circuitry for implementing at least one of the aforementioned components.

Assignee:

Advanced Micro Devices, Inc. - Sunnyvale CA

International Classification:

H01L 2348

US Classification:

357 70

Abstract:

A metal lead frame for an integrated circuit package is disclosed having stress relieving means formed therein to inhibit breakage of a thermally mismatched silicon die subsequently attached thereto and then heated during normal operation of the device. The stress relieving means may comprise parallel grooves formed in one or both surfaces of the central portion of the lead frame where a silicon integrated circuit die will subsequently be bonded to the lead frame. Preferably, the grooves are formed in both axes comprising the plane of the lead frame and may be formed on both surfaces of the lead frame. The stress relieving means may also comprise a series of openings cut through the central portion of the lead frame.
