Abstract: An active matrix liquid crystal display device includes a pair of substrates that seal a liquid crystal, thin film transistors, display pixel electrodes, m/s (s and m are natural numbers that render m/s a natural number) drain bus lines, s×n gate bus lines, and a controller. The thin film transistors are arranged on one of said substrates to form a matrix of n rows×m columns.

The drain bus lines are connected to drain electrodes of the matrix-type thin film transistors in s-to-1 correspondence. The gate bus lines are connected to gate electrodes of the thin film transistors on each row in one-to-one correspondence. The controller selects n gate bus lines in each of s frames starting from an (s×t(t is an arbitrary positive integer)+1)th frame and ended with an (s×t+s)th frame to perform one-screen display with the s frames.

Abstract: A power management system includes a detector (1) for generating a transition number (NI) indicating the number of transitions in a video signal (VI) during a selected period in time of the video information (VI). This is repeated in successive periods in time wherein video information (VI) is written to the same area of the display screen (6). In this way, a sequence of transition numbers (NI) occurs representing the number of transitions in the video signal (VI) for the same area of the display screen (6) in successive periods of time. A comparator (3) compares the transition numbers (NI), and a controller (4) activates a power down mode of the monitor when at least two of said transition numbers (NI) is substantially equal, which indicates that the video signal (VI) in the selected area has the same number of transitions in the different time periods, and thus, it is likely that the video signal (VI) did not change.

Abstract: A touch panel is constructed of a top sheet member having a resistive membrane on its inner surface and a base sheet member having a resistive membrane on its inner surface, the top and base sheet members facing each other with dot spacers being located in between. The top sheet member is formed by laminating a bulge-resistant film, a polarizing plate, a quarter wavelength plate, and a light isotropic film in this order from above. A PET film which is not heat-treated so as to have a higher thermal contraction rate than the other members of the top sheet member underneath such as the polarizing plate, is used as the bulge-resistant film. Since the bulge-resistant film contracts more than the polarizing plate under a high ambient temperature, after the ambient temperature returns to normal, the bulge-resistant film does not become slack against the polarizing plate. Accordingly, the top sheet member can be kept from bulging outward.

Abstract: A method of compensating for differential aging of independent emitters in a display is disclosed. According to the method, an image on the display is periodically sampled to determine how often each independent emitter is used. A history is compiled of the use of each independent emitter for a predetermined time. The amount of luminance decay that each independent emitter has experienced over the predetermined time is estimated. The maximum luminance of each independent emitter is adjusted so that the maximum luminances of all of the independent emitters is substantially the same as the maximum luminance of the independent emitter that has experienced the most decay.

Abstract: First and second gradation bit groups are obtained by dividing m (4≦m<n) gradation bits from the most significant bit into two halves so as to make weights thereof half where n is a total number of gradation bits. Then, a plurality of sub-fields in the first and second gradation bit groups is arranged to be equal to each other. Subsequently, at least part of sub-fields of (n−m) non-divided gradation bits among the n gradation bits are arranged in between the first and second gradation bit groups. A time interval between the first and second gradation bit groups is thereby determined to be h/2±h/14 (msec), where h (msec) is time of one field of a video signal to be displayed.

Abstract: Light is shined on an addressable spatial light modulator, and the light is also integrated. The data displayed on the spatial light modulator is changed when the integrated light reaches a predetermined value. The light may impinge on the spatial light modulator through a color wheel, which may be rotated faster than the frame repetition rate of video information that is being displayed. Alternatively, the light may be generated by different-colored lamps. The intensity of the light may be controlled in accordance with the bit rank or significance of the bits that are being displayed by the spatial light modulator. Several techniques for achieving different intensity levels are disclosed.

Abstract: Novel addressing schemes for controlling bistable electronically addressable displays include the use of addressing signals with additional signals having opposite polarity and equal integrated signal strength, and addressing schemes that minimize the number of state changes that a display element undergoes. In one embodiment, pre-pulses are employed to apply a pre-stress to an display element that is equal and opposite to the electrical stress applied in addressing the element. In another embodiment, the addressing signal is followed by a post-stressing pulse. Methods for minimizing the number of display elements that must change state to change the image displayed include the determination of a set of elements that must be deactivated and a set of elements that must be activated to change the image depicted by a display. Alternatively, only the elements forming one image are deactivated before the elements forming a different image are activated.

Abstract: In a display device in accordance with the present invention, each pixel includes a plurality of luminescent elements having different luminous intensities to represent gray scales by controlling the turning ON/OFF of the luminescent elements. A digital signal is transmitted to each pixel to carry out control by thin film transistors connected in series with the luminescent elements. The luminous intensities of the luminescent elements are the geometric progressions of a common ratio of 2. The ON resistance of the thin film transistors is set to be lower than the ON resistance of the luminescent elements, while the OFF resistance of the thin film transistors is set to be higher than the OFF resistance of the luminescent elements. These features have reduced the nonuniformity in the luminous intensities of the luminescent elements caused by the nonuniformity in the conductance of the transistors, thus achieving improved image quality.
