    Abstract: The present invention relates to a light emitting device for reducing consumption of an electric power in screen protecting mode. The light emitting device includes a plurality of data lines, a plurality of scan lines, a plurality of pixels, a controller, a data driving circuit and a scan driving circuit. The data lines are disposed in a first direction. The scan lines are disposed in a second direction different from the first direction. The pixels are formed by the data lines and the scan lines. The controller transmits a plurality of first display data. The data driving circuit provides data current corresponding to the first display data transmitted from the controller to the data lines. The scan driving circuit drives the scan lines by a unit of two or more lines under control of the controller when the first display data are repeatedly transmitted to the data driving circuit.

    Abstract: The invention provides a display device and an electronic apparatus which can reduce power consumption in the case of being driven by using a digital time grayscale method. According to the invention, a row in which all the pixels display black is focused on in a plurality of pixels arranged in matrix, and sampling of data which is to be inputted to the pixels arranged in the row is not performed. Then, in a period during which the data sampling is not performed, the operation of a shift register in a source driver and sampling operation of a video signal in a first latch circuit are stopped. The invention which has the aforementioned characteristics can temporally stop operation of the source driver to reduce power consumption. In particular, the invention can stop operation of the source driver which consumes much power in the display device, leading to dramatic reduction in power consumption.

    Abstract: A wireless handheld communications device with a liquid crystal display, especially, a field sequential liquid crystal display, includes a visual notification for a powered up, inactive state. The visual notification is preferably through a light emitting diode that may be part of the backlighting system for the LCD or may be independent from the backlighting system. The waveforms, periodicity, colour selection, and colour sequencing may be customizable by one or both of the manufacturer and user.

    Abstract: The present invention relates to a driving circuit (40) of a liquid crystal display (30) and a driving method thereof. The method includes receiving an M-bit image data from an image data input terminal (41) and extracting N most significant bits (MSB) of the M-bit image data to form an N-bit image data. The N-bit image data is delayed by one frame period to form an N-bit delayed image data and is compared with P MSB of a current M-bit image data, P≥N. The result of said comparison is used to determine whether to generate a first data voltage according to a first image value (52,72,92) selected from a reference table (50,70,90), or to generate a second data voltage according to the current M-bit image data. In an alternative embodiment the result of said comparison is used to determine whether to generate a first data voltage selected from a reference table (50,70,90), or to generate a second data voltage according N MSBs of a first image value selected from said reference table and Q LSBs of the current M-bit image data.

    Abstract: Driver system (10) for use in connection with a non-linear display array having NxM pixels. The driver system (10) comprises an input for receiving column data representing an image to be displayed, and a row driver designed to sequentially collect the currents of all M pixels of each row of pixels row electrode by row electrode. A gamma correction unit (17) is employed that provides for a gamma correction of the column data. The gamma correction unit (17) is situated at the input side of a display data memory (14) for storing the gamma corrected column data. The driver system (10) further comprises a column driver (24) designed to apply column signals to all M column electrodes in parallel, the column signals being generated in accordance with the gamma corrected column data.
