Abstract: A liquid crystal display (LCD) device comprises a liquid crystal panel having a plurality of pixel regions defined by a plurality of gate lines and data lines, each pixel region associated with a thin film transistor, a gate driving unit having an amorphous semiconductor and integrally formed with the liquid crystal panel capable of sending a scan signal to the gate lines having a pulse width longer than a turned on time of the thin film transistor located within the pixel region, and a data driving unit connected to the data lines capable of sending an image signal to the data lines.
Abstract: Methods and systems are provided for automatically calibrating a pointing device, such as a stylus, with a writing surface, such as a touch screen. In one example, an automated method is implemented to calibrate the writing surface based user inputs attempting to use the computer for functions other than calibration of the writing surface. The user inputs may be, for example, a user selecting a button within a non-calibration software application. The automated method may generate a miscalibration vector based upon where the user input was received and where the user input was expected. In yet another example, a bias field may be generated for the writing surface from the collected user inputs. In yet other examples, a computing device may comprise computer-executable instructions for performing one or methods of calibrating the writing surface.

Abstract: A touch screen digitizing system includes a first resistive screen and a touch screen controller including an ADC and self-test circuitry having a driver switch coupled between a reference voltage and a first terminal of the first resistive screen, and a first test switch coupled between ground and a conductor connected to generate a first test voltage on the conductor indicative of connection resistance between the first resistive screen and the touch screen controller. Another test switch couples the test voltage to an input of the ADC. An output of the ADC is compared with a reference to determine whether the connection resistance is excessive. Connection resistance between a second resistive screen and the touch screen controller is measured similarly. Similar self-test circuitry operates to detect a short circuit between the first resistive screen and the second resistive screen.
Abstract: Plural controller circuits capable of mutually exchanging data are used as a display controller, the plural controller circuits connected to each other via a data bus. Each of the controller circuits, which receives image data, (i) transfers image data other than image data of a screen region, driving of which the controller circuit is in charge of controlling, on the other hand, (ii) stores, into a line memory section thereof, the image data of the screen region, driving of which the controller circuit is in charge of controlling together with image data that is transferred from another controller and that is for the screen region, driving of which the controller circuit is in charge of controlling, and converts the thus stored image data into output image data. This makes it possible to establish common use of a display controller for different resolutions so as to provide cost merit.
Abstract: The present invention provides an image display device capable of freely changing a scanning direction of an image display medium including support plates, first and second electrode groups provided at the plates and colored particles provided between the plates, including first and second electrode-driving components which receive electrode-designation signals and apply voltages to the designated electrodes in the first and second electrode groups, and which can apply voltage to plural electrodes simultaneously, a line-image-data generation component which generates line-image-data for line images to be displayed along scan electrodes in accordance with a scanning direction, and a signal-output-destination-switching component, in accordance with the scanning direction, which outputs a first electrode designation signal for designating a scan electrode of a line image and a second electrode designation signal for designating an electrode to be driven for displaying the line image, to the first electrode drivi
Abstract: A pixel circuit, display device, and method of driving a pixel circuit enabling source-follower output with no deterioration of luminance even with a change of the current-voltage characteristic of the light emitting element along with elapse, enabling a source-follower circuit of n-channel transistors, and able to use an n-channel transistor as a drive transistor of a light emitting element while using current anode-cathode electrodes, wherein a capacitor C111 is connected between a gate and source of a TFT 111 as a drive transistor, a source side of the TFT 111 is connected to a fixed potential (for example GND) through the TFT 114, the gate and drain of the TFT 111 are connected through the TFT 113 to cancel the threshold value Vth, the threshold value Vth is charged in the capacitor C111, and the input voltage Vin is coupled with the gate of the TFT 111 from the threshold voltage Vth.
Abstract: Various technologies are provided to facilitate the use of a pointer (e.g., a cursor) with a large display (including displays that comprise multiple monitors). For example, solutions are presented for quickly moving the pointer across multiple monitors and for using multiple pointing devices. An interface is further provided with the ability to render an arbitrary image that trails the pointer to make the pointer easier to find on the large display. This image can visible be visible at all times, visible when requested by the user, or visible in response to a minimum amount of movement during a defined time period.
