20120075262 | UNDER-RUN COMPENSATION CIRCUIT, METHOD THEREOF, AND APPARATUSES HAVING THE SAME - An under-run compensation circuit is provided. The under-run compensation circuit is configured to receive a clock signal, data, and an under-run detection signal that indicates whether or not an under-run is occurring. The under-run compensation circuit is further configured to output the clock signal and the data when receiving the under-run detection signal that indicates that an under-run is not occurring. The under-run compensation circuit is additionally configured to output the clock signal and dummy data when receiving the under- run detection signal that indicates that an under-run is occurring. | 03-29-2012 |
20120194512 | THREE-DIMENSIONAL IMAGE DATA DISPLAY CONTROLLER AND THREE-DIMENSIONAL IMAGE DATA DISPLAY SYSTEM - A display controller can include a blending coefficient storing unit and an image mixing unit. The blending coefficient storing unit can store blending coefficients. The image mixing unit can receive left-eye image data and right-eye image data, and generate three-dimensional image data by performing a blending operation on the left-eye image data and the right-eye image data using the blending coefficients stored in the blending coefficient storing unit. | 08-02-2012 |
20120195503 | IMAGE PROCESSING DEVICE - An image processing device includes a first image enhancer and a second image enhancer. The first image enhancer receives first image data and generates first image enhancement information by analyzing the first image data. The second image enhancer receives second image data and generates second image enhancement information by analyzing the second image data. The first image enhancer converts the first image data into first enhanced image data based on the first image enhancement information and the second image enhancement information. The second image enhancer converts the second image data into second enhanced image data based on the first image enhancement information and the second image enhancement information. | 08-02-2012 |
20130155036 | DEVICES AND METHOD OF ADJUSTING SYNCHRONIZATION SIGNAL PREVENTING TEARING AND FLICKER - A display controller includes a synchronization signal adjusting circuit, which adjusts at least one of the delay and the pulse width of a synchronization signal generated in a display driver and outputs an adjusted synchronization signal, and a transmission timing control circuit configured to control the transmission timing of display data, which will be transmitted to the display driver, in response to the adjusted synchronization signal. | 06-20-2013 |
20140028692 | SYSTEM ON CHIP AND ELECTRONIC SYSTEM INCLUDING THE SAME - A system on chip (SoC) includes a first display subsystem configured to perform first and second imaging functions and a second display subsystem configured to only perform the first imaging function. The SoC is configured to activate one of the display subsystems and deactivate the other display subsystem based on a comparison of a current frame of image data and a previous frame of image data. | 01-30-2014 |
20140078198 | METHODS AND DEVICES FOR CONTROLLING OPERATIONS OF AN ORGANIC LIGHT-EMITTING DIODE DISPLAY - In one example embodiment, a method of operating an image data processing circuit which controls an operation of an organic light-emitting diode (OLED) display includes transforming at least one first RGB value into at least one luminance value and at least one chroma value. The method further includes adjusting the at least one luminance value and the at least one chroma value based on at least one first control value. The method further includes generating at least one second RGB value based on the at least one adjusted luminance value and the at least one adjusted chroma value. The method further includes outputting the second RGB values to the OLED display. | 03-20-2014 |
20140160106 | DISPLAY CONTROLLER AND APPARATUSES INCLUDING THE SAME - A display controller includes at least one first power domain configured to receive power according to a type of image data, and at least one second power domain configured to receive power regardless of the type of the image data. | 06-12-2014 |
20140218378 | SYSTEM ON CHIP FOR UPDATING PARTIAL FRAME OF IMAGE AND METHOD OF OPERATING THE SAME - A system on chip (SoC) and a method of operating the same are provided. The SoC includes a central processing unit (CPU) controlling a memory operation and a display operation on a current frame of an image based on generation of the image and an interrupt signal; an image generator requesting data of the current frame from a memory according to control of the CPU; a UD unit determining whether the current frame is updated, detecting whether an update region is a partial frame based on virtual addresses included in a request of the image generator, and outputting the interrupt signal corresponding to the update region to the CPU; a memory controller storing the update region in the memory according to the control of the CPU; and a display controller accessing the memory and outputting the update region to a display device according to the control of the CPU. | 08-07-2014 |
20140258664 | METHOD AND APPARATUSES FOR READING DATA - A method of reading data includes setting first addresses defining a full image and second addresses defining a blocking region included in the full image and not reading blocking region data corresponding to the blocking region among image data corresponding to the full image using the first addresses and the second addresses. | 09-11-2014 |
20140267329 | System on Chip, System Including the Same, and Operating Method Thereof - A method of operating a display system may include receiving an indication signal indicating a data update, receiving data, and updating a whole frame on the display with an image corresponding to the data based on the indication signal corresponding to a whole frame or updating a partial frame on the display with an image corresponding to the data based on the indication signal corresponding to a partial frame. | 09-18-2014 |
