Abstract: A display may have an array of pixels. Display driver circuitry may supply data and control signals to the pixels. Each pixel may have seven transistors, a capacitor, and a light-emitting diode such as an organic light-emitting diode. The seven transistors may receive control signals using horizontal control lines. Each pixel may have first and second emission enable transistors that are coupled in series with a drive transistor and the light-emitting diode of that pixel. The first and second emission enable transistors may be coupled to a common control line or may be separately controlled so that on-bias stress can be effectively applied to the drive transistor. The display driver circuitry may have gate driver circuits that provide different gate line signals to different rows of pixels within the display. Different rows may also have different gate driver strengths and different supplemental gate line loading structures.

Abstract: A wireless communication device includes a transceiver and processing circuitry. The transceiver is configured to establish a telecommunication connection with a total usable bandwidth. The processing circuitry is coupled to the transceiver. The processing circuitry is configured at least to monitor a foreground throughput of data transmission induced by a foreground application program and a background throughput of data transmission induced by a background application program over the telecommunication connection. The processing circuitry is further configured at least to detect whether the foreground application program and the background application program compete for the total usable bandwidth or not according to variations of the foreground throughput and the background throughput.

Abstract: A system and method for sending a current position of a communication device comprising a global positioning system detects current position of the communication device by the global positioning system when the communication device communicates with a receiving communication device, so as to acquire current position data and communication data from the communication device to the receiving communication device. The system and method further encodes and packs the current position data and the communication data, to generate a data package, and sends the data package to the receiving communication device.
