摘要： A method is provided of determining the pixel drive signals to be applied to the pixels of an array of light emitting display elements arranged in rows and columns, with a plurality of the pixels in a row being supplied with current simultaneously along a respective row conductor. Target pixel drive currents are determined from a model of the pixel current-brightness characteristics. These are modified to take account of the voltage on the respective row conductor at each pixel resulting from the currents drawn from the row conductor by the plurality of pixels and the dependency of the pixel brightness characteristics on the voltage on the row conductor at the pixel. This addresses the problem of horizontal cross-talk that occurs in active matrix LED displays due to the finite output impedance of the current providing TFTs as well as the finite resistance of metals used to form power supply lines.

摘要： An active matrix electroluminescent display device has power supply lines (26) in the column direction. An isolating transistor (30) is provided for isolating a drive transistor (22) of each pixel from the pixel display element (2). The device is operable in two modes. In a first mode, the isolating transistor (30) isolates the drive transistor (22) from the display element (2) for each pixel, and pixel drive signals are provided to all pixels of the array in a row-by-row sequence. In a second mode, the isolating transistor couples the drive transistor to the display element and current is driven through the display elements. In this display device, pixel drive signals are loaded into the display array in one phase, in a row by row manner. As the power supply lines are in columns, during loading of the pixel drive signals, a current is provided to only one pixel along the power supply line at a time. No current is drawn by any display elements during this time, so that vertical cross talk is avoided. This enables pixel data to be stored accurately on the pixels.
摘要翻译：有源矩阵电致发光显示装置在列方向上具有电源线（26）。隔离晶体管（30）被提供用于将像素的驱动晶体管（22）与像素显示元件（2）隔离。该设备可在两种模式下工作。在第一模式中，隔离晶体管（30）针对每个像素将驱动晶体管（22）与显示元件（2）隔离，像素驱动信号以逐行顺序提供给阵列的所有像素。在第二模式中，隔离晶体管将驱动晶体管耦合到显示元件，电流通过显示元件驱动。在该显示装置中，像素驱动信号以一行一行的方式一载入显示器阵列。随着电源线处于列中，在加载像素驱动信号期间，一次仅沿着电源线仅提供一个像素的电流。在此期间任何显示元件都没有画出电流，避免了垂直串扰。这使像素数据能够准确地存储在像素上。

摘要： A transfiective display device (1), comprising: an array of transmissive pixels (4) and reflective pixels (12) arranged such that at least one characteristic of an image is different for the image displayed in transmissive mode compared to the image displayed in reflective mode, for example different resolution, or one mode colour and the other mode monochrome, and arranged to switch off a backlight (190) that provides illumination for the transmissive mode responsive to the ambient light level (304) exceeding a threshold level (316). The device may further, or alternatively, be arranged to drive the reflective pixels (12) in an all-black state responsive to the ambient light level (304) falling below the threshold (316). An additional threshold (318) may be used to provide a hysteresis loop (320-321). These arrangements tend to alleviate the effect of mixed transmissive/reflective mode images at medium ambient brightness levels (312) where the brightness level (306) of the reflective mode and the brightness level (308) of the transmissive mode are similar.

摘要： An active matrix display device comprises an array of picture elements, e.g. liquid crystal picture elements, first and second sets of address conductors (16, 18) extending in row and column directions respectively and connected with the picture elements, and a set of connection conductors (30) extending in the same direction as the second set of address conductors (18), each of which is connected to a respective one of the first set of conductors (16) at the location of a picture element, and via which address signals are supplied to that first set. Picture elements other than those at the locations of the connections between the connection conductors and first set of address conductors are provided with a capacitance between their picture element electrode and their associated address conductor of the first set in order to compensate for the effects of a parasitic capacitance present between the picture element electrodes and the connection conductors which can lead to anomalies in the display outputs of the picture elements following their addressing.

摘要： An active matrix display device comprises an array of picture elements, e.g. liquid crystal picture elements, first and second sets of address conductors (16, 18) extending in row and column directions respectively and connected with the picture elements, and a set of connection conductor lines (30') extending in the same direction as one set of address conductors (18), each of which is connected to a respective one of the other set of conductors (16), and via which address signals are supplied to that other set. To avoid unwanted display artefacts, each connection conductor line (30') extends from one side of the array and terminates adjacent its connection point (32) to its associated address conductor (16) and a respective complementary conductor line (30") is provided which extends from close to the connection point (32) to the opposite side of the array, the complementary conductor line being electrically separate from the connection line (30') and coupled to reference signal supply (40).

摘要： A method of constructing an active matrix pixel device uses a universal active matrix (UAM) comprising a matrix array of switching elements (20) whose spacing defines a base pitch and a pixel array comprising a matrix array of pixel electrodes (19) whose spacing defines a pixel pitch. The pixel pitch is greater than the base pitch. A large proportion of the construction process can be carried out before the customisation of the device. Using a common UAM enables a reduction in the time between the customer ordering the device and the completion time. The cost of meeting customer specific requirements for the fabrication of active matrix pixel devices is thus reduced.
