摘要： An active matrix display device comprises an array of display pixels, with each pixel comprising an EL display element, a light-dependent device for detecting the brightness of the display element and a drive transistor circuit for driving a current through the display element. The drive transistor is controlled in response to the light-dependent device output so that ageing compensation can be implemented. The light-dependent device is located laterally of the area of light emitting material of the EL display element. In this way, the light-dependent device does not cause step coverage problems and can be integrated into the pixel layout without affecting the pixel aperture. Furthermore, the light dependent device can extend alongside the full length of the area of light emitting material so that it receives light input from a large part of the display element area.

摘要： Each pixel of an active matrix electroluminescent display device has a first amorphous silicon drive transistor for intermittently driving a current through the display element and a second amorphous silicon drive transistor for intermittently driving a current through the display element. The aging effect of amorphous silicon TFTs can be reduced by sharing the driving of the display element between two drive transistors. Providing a duty cycle reduces the on-time for each drive transistor, but also provides a period during which there can be some recovery of the TFT characteristics.

摘要： In an active matrix electroluminescent display device, an overall brightness level of an image to be displayed in a frame period is determined. A drive transistor of each pixel is controlled in dependence on an input drive signal for the pixel and on the overall brightness level, for example using a signal processor (30) to vary the pixel drive signals. This arrangement can control the pixels to limit the maximum currents drawn by the pixels, thereby limiting the cross talk effects resulting from voltage drops along row or column conductors. If an image is bright, the pixel drive levels across the image (or at least a part of the image) can be reduced, so that the maximum brightness is reduced.

摘要： An active matrix display device uses an amorphous silicon drive transistor for driving a current through an LED display element. First and second capacitors are connected in series between the gate and source of the drive transistor, with a data input to the pixel provided to the junction between the first and second capacitors. The second capacitor is charged to a pixel data voltage, and a drive transistor threshold voltage is stored on the first capacitor. This pixel arrangement enables a threshold voltage to be stored on the first capacitor, and this can be done each time the pixel is addressed, thereby compensating for age-related changes in the threshold voltage.

摘要： A method and system for selecting and connecting to an access point in a wireless network of devices, such as a Bluetooth network. Initially, an initiator device is preconfigured with a list of available access point addresses. The initiator device broadcasts an inquiry message that is received by available wireless devices which, in turn, respond with their respective addresses, occupancy level and device classification. The initiator device compares the respondent addresses with the preconfigured access point addresses and connects to a match, thus terminating the inquiry, provided certain fitness functions are satisfied. The fitness functions might include such considerations as occupancy rate, device classification, signal strength, or physical distance of separation. The list of addresses on the initiator device is updated automatically upon connecting with a network server whenever a new device is added or an old one removed from the network server's access point address list.
