An array of elements including less than all of the elements in the matrix to display the image is defined. A sweep rate for writing the illumination values for the elements in the array is determined, and a sweep signal having the illumination values for the elements in the array is generated, where the sweep signal writes illumination values for the elements in the array at the determined sweep rate. According to another embodiment of the present invention, a display driver generates an image encoded in the form of illumination values. The driver includes an image source and a controller receiving the image from the image source, said controller being adapted to (1) define an array of elements including fewer than all of the elements in the matrix for display of the image (2) determine a sweep rate for writing illumination values to the array of elements, and (3) generate images by writing illumination values to the elements in the array at the sweep rate.

摘要： A circuit is disclosed for driving an OLED in a graphics display. The circuit employs a current source operating in a switched mode. The output of the current source is connected to a terminal of the OLED. The current source is responsive to a combination of a selectively set cyclical voltage signal and a cyclical variable amplitude voltage signal. The current source, when switched on, is designed and optimized to supply the OLED with the amount of current necessary for the OLED to achieve maximum luminance. When switched off, the current source blocks the supply of current to the OLED, providing a uniform black level for an OLED display. The apparent luminance of the OLED is controlled by modulating the pulse width of the current supplied to the OLED, thus varying the length of time during which current is supplied to the OLED. By using a switched mode of operation at the current source, the circuit of the present invention is able to employ a larger range of voltages to control the luminance values in a current-driven OLED display.

摘要： An LED is an element in which when a voltage pulse applied to the intrinsic diode of an electrical equivalent model reaches a peak value, a current suddenly flows to obtain an optical output proportional to the forward current. By utilizing this property, the LED receives a rectangular voltage pulse having a large-current driving ability at a low output impedance, or a voltage pulse having two high levels. The low level of the voltage pulse is set within a voltage range where the extinction ratio of an output signal from the LED can be maintained. Even in an LED having a large internal capacitance, an increase in power consumption can be minimized, the transient response time can be shortened, high-speed modulation can be performed, and output light almost free from pulse waveform distortion can be obtained.

摘要： A display apparatus is provided which is capable of improving display quality by expanding the light-emission area of pixels by improving the layout of pixels and common power-feed lines formed on a substrate. Pixels including a light-emission element, such as an electroluminescence element or an LED element, are arranged on both sides of common power-feed lines so that the number of common power-feed lines is reduced. Further, the polarity of a driving current flowing between the pixels and the light-emission element is inverted so that the amount of current flowing through the common power-supply lines is reduced.

摘要： A display device that includes video chips. Each video chip is modular and is engageable with adjacent video chips, a plurality of pins that electrically communicate with the set of pins of adjacent video chips, and pixels that electrically communicate with the plurality of pins thereof. Each pixel is engageable with adjacent pixels, a red LED for selective illumination, a green LED for selective illumination, and a blue LED for selective illumination. The video chips are placed in an array of columns and rows which are activated by vertical scanning and horizontal scanning. The rows are supplied with a positive voltage to prevent conduction. The vertical scanning activates each row by reducing back voltage to zero. The horizontal scanning activates each column at three different levels for activating at least one of the red LED, the green LED, and the blue LED.

摘要： Methods of improving the display uniformity of an OLED are disclosed. In order to improve the display uniformity of an OLED, the display characteristics of all organic-light-emitting-elements are measured, and calibration parameters for each organic-light-emitting-element are obtained from the measured display characteristics of the corresponding organic-light-emitting-element. The calibration parameters of each organic-light-emitting-element are stored in a calibration memory. One method for creating the compensated video data-signal is by storing into the video memory the compensated video word that is calculated based on the calibration parameters in the calibration memory and by fetching from the video memory the compensated video word. An alternative method for creating the compensated video data-signal is by fetching from the video memory the uncompensated video word and by using the calibration parameters in the calibration memory to calculate the compensated video data-signal.
