Abstract: Methods, apparatus, and articles of manufacture to provide extended graphics processing capabilities are disclosed. A disclosed example method involves sending a display panel parameter to a shared library module. The display panel parameter is sent by a programmable driver interface in communication between the shared library module and a graphics hardware device driver. The shared library module includes a first graphics processing capability. The graphics hardware device driver includes a second graphics processing capability different from the first graphics processing capability. The example method also involves performing a render operation via the programmable driver interface on a frame buffer based on the first graphics processing capability. The first graphics processing capability is received at the programmable driver interface from the shared library module based on the display panel parameter. The frame buffer is output to a display.

Abstract: Described herein are technologies for color transformation in a graphics processing hardware using at least two hierarchical one or multi-dimensional lookup-tables (LUT) in order to obtain a minimized overall LUT storage space yet achieves transformation output of desired accuracy. Particularly, a first interpolation of an input signal is implemented using a main LUT and successive interpolations using higher order difference LUTs. Outputs of the first and successive interpolations are then combined to generate a transformed pixel output.

Abstract: A device, including: processing circuitry operable to determine boosted subpixel values for subpixels in a camera under display (CUD) area of a display panel, wherein each boosted subpixel value is based on a ratio of a non-CUD subpixel aperture area to a CUD subpixel aperture area for a corresponding subpixel of the display panel; and a display driver operable to boost a brightness of each subpixel in the CUD area based on the respective boosted subpixel value.

Abstract: Methods, systems and apparatuses may provide for technology that generates a seed value, wherein the seed value is dedicated to a position of an input pixel, generates a dithered pixel value based on the seed value and a value of the input pixel, and conducts a scan-out of the dithered pixel value to a display panel. In one example, the technology generates an intermediate value based on the seed value and one or more fixed constants and generates a pseudo random number based on the intermediate value and a programmable constant, wherein the dithered pixel value is generated based on the pseudo random number and the value of the input pixel.

Abstract: If the picture complexity is low then the number of pixels in a frame may be reduced. For example, pixel-to-pixel variation in terms of RGB color values can be used to determine the complexity of the frame. Frames can be characterized, in one embodiment, as non-complex frames with less pixel variation and complex frames with very high pixel variation. The high PPI may be used only for complex frames while non-complex frames can use low PPI. This method reduces memory fetching and pixel processing within the display engine and thereby saves power.

Abstract: Methods and apparatus relating to techniques to provide dynamic pixel density adjustment for display panels not driven by backlight are described. In an embodiment, logic causes a first plurality of pixels of a display panel to be turned off in response to an indication that a charge level of a power supply, coupled to supply electrical power to the display panel, has dropped below a threshold level. The display panel is not backlight drive (such as an OLED or QDOT display panels. Other embodiments are also disclosed and claimed.

Abstract: Methods and systems for dynamically adjusting the power consumption of an organic light-emitting diode (OLED) panel are disclosed. In embodiments, a histogram of a frame to be displayed is generated, and a weighted dimming curve is generated, with heavier weighting given to mid-tone intensity pixels. High and low intensity pixels are left only minimally adjusted. The curve is then capped and smoothed to prevent artifacts and to preserve image contrast. Each pixel in the frame is then dimmed according to the curve, and the resultant transformed frame is displayed on the OLED panel.
