Abstract: A display apparatus that can improve power savings in a waiting mode is disclosed. The display apparatus (0) is used as a display component of an electronic device capable of switching between a normal power consumption state and a low power consumption state and includes a panel in which a display area (2) and a peripheral circuit section for driving the display area are integrally formed on an insulating substrate (1). The circuit section switches between an operation mode and a waiting mode responsive to switching between the normal power consumption state and the low power consumption state of a main body of the electronic device. In the waiting mode, a standby control operation stops driving the display area 2 and inactivates the circuit section to suppress power consumption.

Abstract: A selection-addressing-type liquid crystal display selectively addresses a signal line of a pixel unit using groups of three selectors of a selector circuit in a time-division manner. A level converter level shifts selector pulses having a voltage swing corresponding to the external-circuit power supply to selector pulses having a voltage swing corresponding to the internal-circuit power supply. In a non-display region in partial display mode, the level converter is deactivated under the control of a control signal to reduce direct current consumption therein.

Abstract: A mechanism for synchronizing state variables used by texture pipelines in a multi-pipeline graphics texture engine. The mechanism ensures that, as polygons are processed by a texture engine, the state variables associated with each polygon are distributed in parallel to each texture pipeline, regardless of whether the texture engine is processing a single texture or a blend of different textures. When the texture engine processes a blend of different textures, signals controlling the operation of multiple texture pipelines are asserted. However, when the texture engine processes a single texture for a polygon, an embodiment of the invention continues to distribute received state variables to each of the texture pipelines, but only triggers the processing portion of the texture pipeline performing the single texture operation. The processing portions of the remaining texture pipelines may not be not triggered.

Abstract: A look-up table stores a plurality of polarity pattern tables for setting the polarities of pixel voltages of pixel formation portions on a display screen. The plurality of polarity pattern tables are set such that when each of the polarity pattern tables is selected once, the number of positive polarities appearing at each of the pixel formation portions is the same as the number of negative polarities. The polarity instruction signal generation circuit selects one of the polarity pattern tables based on a random number that is outputted from a random number generation circuit, and outputs a polarity instruction signal based on the selected polarity pattern table. Then, the video signal line driving circuit outputs video signals such that a voltage with a polarity in accordance with the polarity instruction signal is applied to each of the pixel formation portions.

Abstract: A plurality of horizontal display control lines CTL are arranged in parallel with signal lines D and connected to switching elements ctl of pixels. Among pixels whose switching elements sw become an On state owing to a selection voltage from a gate line G, switching elements ctl of pixels for which display signals are not rewritten are turned off not to apply a display signal to liquid crystal cells of those pixels. And pixels for which display signals are to be rewritten, the horizontal display control circuit 109 applies a rewrite selection signal to those pixels to turn on switching elements ctl of those pixels. Thus, applying display signals that are outputted from a signal circuit and correspond to those pixels having the switching elements ctl turned on to liquid crystal cells of those pixels, display signals are rewritten.

Abstract: A main control unit accepts an operation of deciding a touched button when the user releases the button on a touch panel in a menu window within a predetermined time period after touching the button without moving his/her finger along the touch panel. Also, the main control unit accepts an operation of deciding a touched button when the user keeps the button touched for more than the predetermined time period after touching the button without performing finger movement. When the user moves his/her finger along the touch panel to another position after touching a button without releasing the button in the predetermined time period, the main control unit does not accept a button deciding operation by release or long touch thereafter.

Abstract: A liquid crystal display with multi-line inversion which reverses polarity of applied voltages every two or more rows for preventing the deterioration of liquid crystal. An LCD includes a data driver outputting analog gray voltages selected based on the image data to the data lines of the LC panel. The data driver includes a data line bias circuit biasing the data lines to an intermediate level voltage whenever displaying the pixels in one row. Accordingly, the amount of stored charges between the pixels in the rows with polarity inversion and the pixels in the rows without polarity inversion is reduced, and consequently, the luminance difference between the pixels in the rows with the polarity inversion. The application duration of the data signals for pixels in rows with polarity inversion is also extended, such that the difference in charge storage between the two rows is reduced.

Abstract: In a menu window, when a user touches an area outside buttons on a touch panel, a main control unit vibrates the touch panel by using a first vibration pattern. When the user moves his/her finger along the touch panel so as to reach the range of coordinates of one of the buttons, the main control unit generates the first vibration pattern which indicates the acceptance of an operation of selecting the button and changes the color of the button to a color indicating a button selected state when the touched position reaches the range of the button. Then, the main control unit accepts an operation of deciding the button according to a release operation or long touch performed thereafter.

Abstract: An audible indicator such as an audio tone is associated with the importance of data elements displayed on a visual display screen of data processing apparatus such as a personal computer or work station. At least one characteristic of the audible indicator, for example its pitch or frequence of a tone, is associated with the importance of the data elements. When a user selects a particular date element on the screen, for example using a computer mouse, the audible indicator conveys the importance of the selected data element to the user. This enables visually impaired users to readily locate important data elements on a display screen without reading the entire screen using a screen reader.
