摘要： A shift register is provided, for example, for use in scan and data line drivers for an active matrix liquid crystal display. The shift register comprises X stages, where X is an integer greater than 3. A clock signal generator supplies Y-phase clock signals, where Y is greater than 2. Each of the stages comprises a flip-flop and logic circuit and receives a set enable signal from the immediately preceding stage output. Each stage is set by the leading edge of one of the clock phases in the pressure of the set enable signal and is reset by the trailing edge of the clock phase. In order to provide bi-directional operation, each intermediate stage also receives set enable signals from the immediately succeeding stage output. The clock signal generator supplies clock pulses in a first order for shift register operation in the forward direction and in the reverse order for shift register operation in the reverse direction.

摘要： A display device and method driving a display device makes use of the dynamic variation in the brightness of a surface mode liquid crystal device cell having a liquid crystal layer with a non-zero twist angle. The liquid crystal layer is switched before the equilibrium value of the brightness has been reached, so as to make use of the non-equilibrium increased brightness and so increase the brightness of the display.

摘要： An addressable matrix display comprises an addressable matrix of pixels, a first set of electrode tracks on one side of the matrix and a second set of electrode tracks on the other side of the matrix. The sets of electrode tracks cross one another at the locations of the pixels, and the pixels are switchable by the application of respective switching waveforms to the electrode tracks. Furthermore at least one of the electrode tracks has a resistance which varies along the length of the electrode track in order to provide increased temperature uniformity over the display due to power dissipation during switching by the switching waveforms applied to the electrode tracks. More particularly the resistance in an intermediate section of the electrode track is greater than the resistance in two end sections of the electrode track.

摘要： A display comprises a parallax optic (2), such as a combined parallax barrier and lens array, and a pixellated display device (1). The pixels of the display device (1) are arranged as groups cooperating with a parallax element (4) of the parallax optic (2). Each group comprises a first pixel (A) aligned with the centre of the parallax element (4), second and third pixels (B, C) on either side of the first pixel (A), and fourth pixels (D) shared with adjacent groups and disposed outside the second pixels (B, C). The parallax elements (4) make the different pixels of each group visible in different viewing regions. A control arrangement selects regions of the display and selects different combinations of the pixels of each group for image display within respective regions so as to provide simultaneously-present different viewing modes having different viewing range characteristics.

摘要： A display device is provided, including a signal transmission mechanism that makes it possible to reduce the number of pins on an FPC board connected to a TFT substrate or eliminate the necessity for the FPC board, and that can be readily applied to a compact device.The present liquid crystal display device includes light detectors, a receiver circuit, a display control circuit, a video signal line drive circuit, a scanning signal line drive circuit, and a display portion, which are formed on a TFT substrate of a liquid crystal display panel, and it also includes white LEDs, and an LED drive circuit, which are included in a backlight portion. The LED drive circuit drives the white LEDs, each emitting a light (modulation) signal LS in accordance with an externally-provided video signal VS. The receiver circuit generates (demodulates) the video signal VS based on a signal received via the light detector. Such an optical transmission mechanism makes it possible to reduce the number of pins on the FPC board or eliminate the FPC board.
