Disclosed is a display unit provided with a display control printed circuit board with a circuit configured to generate a display signal for display by a display panel and a fixing metal plate for securing the display control printed circuit board. The display control printed circuit board is provided with identification information reading means for reading identification information of the display panel, a memory stored with set values for generating display signals corresponding to the sizes of a plurality of display panels, and a display controller configured to generate the display signals. The fixing metal plate comprises one or more members electrically connected to the display control printed circuit board and configured to transmit the identification information of the display unit to the display control printed circuit board. The identification information reading means reads a set value for the display panel from the memory, based on the identification information of the display panel derived from the one or more electrically connected members, and sets the set values in the display controller configured to generate the display signals.

An electronic device is provided. The electronic device includes a first display panel including a first clock generator and that generates a first signal according to the first clock generator in response to a screen update request signal, a second display panel including a second clock generator and that generates a second signal according to the second clock generator in response to a screen update request signal, and a controller that transmits the screen update request signal to the first display panel and the second display panel and that receives the first signal and the second signal and that compares the first signal and the second signal to adjust a clock of at least one of the first clock generator and the second clock generator.

The present application relates to an apparatus for verifying the integrity of image data comprising mapped texture data is provided and a method of operating thereof. A fragment shader unit is coupled to first and second frame buffers and at least one texture buffer. A first texture sampler unit is configured to output texture mapped fragments to the first frame buffer. A second texture sampler unit is configured to output texture mapped fragments to the second frame buffer. A comparator unit is further configured to compare the image data stored in the first frame buffer and in the second frame buffer. A fault indication signal is issued in case the image data of the first and the second frame buffers mismatch.

An image display system is configured such that an image display device and an image processing device are connected to each other through a network. The image display device is provided with: an instruction information generation unit for generating instruction information pertaining to image-processing to be performed on an image input signal; an image signal transmission unit for transmitting the instruction information to the image processing device; a corrected signal reception unit for receiving a corrected image input signal obtained through image-processing performed by the image processing device on the basis of the instruction information; and a display signal output unit for outputting an image output signal based on the corrected image input signal, to an object where an image is to be displayed. The image processing device receives the image input signal connected through the network and performs image-processing on the image input signal according to the instruction information.

Methods of rendering a scene in a graphics system identify a draw call within a current render and analyse the last shader in the series of shaders used by the draw call to identify any buffers that are sampled by the last shader and that are to be written by a previous render that has not yet been sent for execution on the GPU. If any such buffers are identified, further analysis is performed to determine whether the last shader samples from the identified buffers using screen space coordinates that correspond to a current fragment location and if this determination is positive, the draw call is added to data relating to the previous render and the last shader is recompiled to replace an instruction that reads data from an identified buffer with an instruction that reads data from an on-chip register.

A display device which supports a panel self refresh (“PSR”) mode includes a source unit and a synchronizing unit, and a signal is transmitted between the source unit and the synchronizing unit through an interface. The source unit determines on/off of the PSR mode in response to a PSR setting value, and additionally determines whether to activate the PSR mode in response to luminance information.

A display device includes a display panel, a controller, and a data driver. The display panel includes a plurality of pixels. The controller detects a logo region including a logo in image data, determines a correction gain based on a first average gray level of the logo region and a second average gray level of a peripheral region adjacent to the logo region, and generates corrected image data by correcting the image data based on the correction gain. The data driver provides data signals to the plurality of pixels based on the corrected image data.

A method and light-emitting diode (LED) device configured to compensate for crosstalk between rows of the LED device.

Techniques are disclosed for processing graphics objects in a stage of a graphics processing pipeline. The techniques include receiving a graphics primitive associated with the graphics object, and determining a plurality of attributes corresponding to one or more vertices associated with the graphics primitive. The techniques further include determining values for one or more state parameters associated with a downstream stage of the graphics processing pipeline based on a visual effect associated with the graphics primitive. The techniques further include transmitting the state parameter values to the downstream stage of the graphics processing pipeline. One advantage of the disclosed techniques is that visual effects are flexibly and efficiently performed.

An information handling system includes a display, a gaze detector that determines a location on the display that corresponding with where a user is looking at the display, and a processor. The processor receives the location from the gaze detector, determines a non-power-reduced portion of the display that includes the location, determines a power-reduced portion of the display that is exclusive of the non-power-reduced portion, receives data associated with a pixel of an image included in the power-reduced portion, changes the data such that a first power level consumed by the display when displaying the pixel with the changed data is less than a second power level consumed by the display when displaying the pixel with the unchanged data, and sends the changed data to the display.
