  • Patent number: 9709833
    Abstract: The general field of the invention is that of the display devices that comprise an active liquid crystal matrix of twisted nematic type. The matrix comprises a set of pixels, a set of rows and of columns and an electronic control device. Each pixel is controlled by a transistor. The voltage applied to each control row is either a switch-on voltage VG_on sufficient to switch on the transistors, or a switch-off voltage VG_off sufficient to switch off the transistors. The voltage applied GMA to each column is dependent on the predetermined optical transmission of the pixel. The display device comprises means for detecting the correct operation of the electronic control device. In case of detection of incorrect operation, the display device comprises cut-off means arranged to force to zero the switch-off voltages VG_off of the rows and the GMA voltages of the columns, so that the transmission of all the pixels of the first set is minimum.

  • Patent number: 9383919
    Abstract: Described techniques enable a computing system to receive character string input (e.g., words, numbers, mathematical expressions, symbolic strings, etc.) by detecting and interpreting an input movement across a user-interface. A touch-based computing system may, for instance, detect an input movement by tracking the path of a pointing element (e.g., a stylus or finger) as it is dragged across a contact-sensitive input surface (e.g., a touch-sensitive screen or external touch pad). Then, the system may interpret the detected input movement using Hidden Markov Modeling.

  • Patent number: 9349325
    Abstract: It is an object to provide a transmissive liquid crystal display device in which power consumption is reduced and deterioration in display quality is suppressed. As a backlight, a surface-emission light source is employed. The light source is a light source which performs surface light emission, so that the light emission area is large. Accordingly, the backlight can effectively radiate heat. Thus, even in the case where an image signal is not input to a pixel for a long period, the pixel can hold the image signal. In other words, both a reduction in power consumption and a suppression of deterioration in display quality can be realized.
