摘要： A laser method is provided for minimizing variations in transistor threshold voltages. The method supplies a wafer with a laser-crystallized active semiconductor film having a top surface with a first surface roughness. The method laser anneals the active semiconductor film, and in response to the laser annealing, melts the top surface of the active semiconductor film. The result is a top surface with a second roughness, less than the first roughness. More explicitly, the wafer active semiconductor film is crystallized using a laser with a first fluence, and then laser annealed with a second fluence, less than the first fluence. As compared with complementary metal-oxide-semiconductor field-effect (CMOSFET) thin-film transistor (TFT) structures formed in unprocessed regions of the active semiconductor film, the TFT threshold voltage standard deviation for TFTs in laser annealed portions of the active film are 60% less for n-channel and 30% less for p-channel TFTs.

摘要： An Auxiliary Electronic Program Guide (AEPG) television system is provided with a receiver having a network interface to accept broadcast channel information, including programs with visual content and Electronic Program Guide (EPG) information describing the programs. The receiver converts selected programs into display data supplied at a display interface. A display has an input to accept the display data and a screen to present images for the selected channels. An auxiliary module converts the EPG information into a code signal representing the EPG information. A user interface (e.g., the display screen) supplies the code signal to a remote device. For example, the auxiliary module converts the EPG information into code signal enabled as a compact code image, and the display screen presents the compact code as an image. In one aspect, the compact code image is a 2D barcode.

摘要： A video display is provided with a planar piezoelectric transmitter to transmit ultrasound signals, and a display panel including a plurality of pixels. Each pixel has a data interface to accept a video signal with a variable voltage associated with a range of light intensity values, and to supply a touch signal with a variable voltage derived from a range of reflected ultrasound signal energies. Each pixel is made up of a light device to supply light with an intensity responsive to the video signal voltage, and a storage capacitor to maintain a video signal voltage between refresh cycles. A piezoelectric transducer accepts a reflected ultrasound signal energy and maintains a touch signal voltage between refresh cycles. In one aspect, the storage capacitor and the piezoelectric transducer are the same device. The light device may be a liquid crystal (LC) layer or a light emitting diode.
