345558000 | First in first out (i.e., FIFO) | 8 |
20090289948 | DISPLAY DEVICE AND METHOD FOR CONTROLLING BACKLIGHT THEREOF - A display device having backlight and the backlight control method thereof is provided. Through the provided method, it is capable of fast determining which intensity range the intensity signal from the means for measuring the intensity of external light falls in, so that the turn-off period of backlight is reduced to avoid the decrement of brightness. | 11-26-2009 |
20100073388 | UNIFIED MEMORY ARCHITECTURE AND DISPLAY CONTROLLER TO PREVENT DATA FEED UNDER-RUN - A display controller for controlling data in an isochronous display where fluctuation of data feed latency occurs, the display controller including an input memory which receives pixel data and transmits the pixel data through a main route and a secondary route; wherein pixel data is transmitted through the main route and is processed for delivery to the display in a predetermined manner; characterised in that the secondary route comprises a memory for storing a two-dimensional section of the pixel data that corresponds at least in part to the pixel data being transmitted through the main route at that time; further characterised in that the display controller includes a detector for identifying a data feed latency event and in response there to switching the transmission of the pixel data to the secondary route and processing the pixel data through secondary route for delivery to the display such that when a data feed latency event occurs the stored two-dimensional section of the pixel data from the secondary route is displayed on the display. | 03-25-2010 |
20100238186 | Display Controllers Including Memory Controllers - A display controller is provided. The display controller includes an external memory and a timing controller which compresses current frame data to generate front first in-first out (FIFO) input data, temporarily stores the front FIFO input data and writes the front FIFO input data to the external memory in a burst mode, and reads data from the external memory in the burst mode, temporarily stores the read data as back FIFO output data, and decodes the back FIFO output data to output previous frame data. | 09-23-2010 |
20120081381 | DISPLAY DRIVE DEVICE, DISPLAY DEVICE, DRIVING CONTROL METHOD, AND ELECTRONIC DEVICE - display drive device includes a correction data memory circuit, a data reading control circuit, and an image data correction circuit. The correction data memory circuit stores a plurality of pieces of correction data according to characteristics of pixels in association with positions where the pixels are arranged in a display panel. The data reading control circuit sets a reading order of the plurality of pieces of correction data to an order corresponding to a display form and reads the correction data in the set reading order. The image data correction circuit associates the image data with each of the plurality of pieces of correction data and generates corrected image data obtained by correcting the image data using the corresponding correction data. | 04-05-2012 |
20120133661 | DISPLAY DRIVING CIRCUIT AND DISPLAY DEVICE INCLUDING THE SAME - A display driving circuit includes a clock dividing unit and a data processing unit. The clock dividing unit receives a first clock signal, generates a second clock signal having a second clock frequency by dividing the first clock signal having a first clock frequency, and outputs the second clock signal. The data processing unit receive the first clock signal, the second clock signal, and input data with a first data frequency, separates input data into first data and second data, outputs the first data based on the second clock signal, and outputs the second data with a second data frequency based on the first clock signal. | 05-31-2012 |
20120147024 | DATA PACKER FOR PACKING AND ALIGNING WRITE DATA - A data packer of an input/output hub of a computer system packs and formats write data that is supplied to it before the write data is written into a memory unit of the computer system. More particularly, the data packer accumulates write data received from lower bandwidth clients for delivery to a high bandwidth memory interface. Also, the data packer aligns the write data, so that when the write data is read out from the write data packer, no further alignment is needed. | 06-14-2012 |
20130155086 | METHOD AND APPARATUS FOR PROVIDING LOCAL SCREEN DATA TO A SINK DEVICE - A method and apparatus is provided for providing local screen data of a source device, such as a personal computer, to a sink device, such as a television, game console, or home theatre system, at a rate determined by the sink device. In one example, the method and apparatus responds to requests from the sink device to provide local screen data by serving the local screen data to the sink device from a circular buffer. The local screen data is written to the circular buffer in FIFO order based on the requests from the sink device, and read from the circular buffer based on the requests. | 06-20-2013 |
20160163290 | DISPLAY SYSTEM, A METHOD OF DISPLAYING AN IMAGE ON A SCREEN AND AN ASSOCIATED COMPUTER PROGRAM PRODUCT - A display system and a method of displaying an image are hereby presented. The display system is arranged to display an image on a screen which has at least one useful screen area which is intended to be seen by a user and at least one non-useful screen area which the user cannot see. The display device comprises a bandwidth saver unit arranged to determine a location on the screen of a current pixel to be displayed. If the pixel is located in a non-useful screen area of the screen, then the fetching from a data memory of a pixel value is inhibited by the bandwidth saver unit with respect to this pixel, and a replacement, fixed pixel value is passed to a data processing unit for further processing. | 06-09-2016 |
