A display includes a display surface, an electroluminescent panel, which has a plurality of electroluminescent elements, and a liquid crystal panel, which has a plurality of liquid crystal elements. The liquid crystal panel and the electroluminescent panel overlaps each other in the front and rear direction of the display. The electroluminescent elements and the liquid crystal elements are aligned with each other in the front and rear direction of the display. In the display, at least one of the...

In a display device of the invention, driving of the piezoelectric element is controlled to change the light path of the propagating light inside a light guiding plate. By illuminating a liquid crystal panel in this manner, an illumination time and a no illumination time can be provided for the liquid crystal panel within one frame period. This realizes impulse-type-like display in displaying moving images on the liquid crystal panel, and thereby improves an image quality of moving images. Furth...

A display is provided with a self-light emitting display unit and includes: first means detecting the maximum value of input signals on each line; second means not only determining which of predetermined plural classes each line belongs to using the maximum value of the line and predetermined threshold values, but also calculating a total number of lines belonging to each class; and third means determining the number of lighting-up times in each class in one field period based on the total numbe...

An active matrix electroluminescent device provides a gray scale display. The device comprises a first electrode layer including a plurality of individually addressable pixel electrodes, a second electrode layer, and a stack including at least a phosphor layer which produces light upon the application of an electric field across the phosphor layer and a dielectric layer. The stack is disposed between the first and second electrode layers. The second electrode layer is driven during the first sub...

A display capable of suppressing reduction of a scanning property is provided. This display comprises a shift register circuit formed by connecting a plurality of first circuit parts each including a first conductivity type first transistor connected to a first potential and turned on in response to a clock signal, a first conductivity type second transistor connected to a second potential and a first conductivity type third transistor, connected between the gate of the first transistor and the ...

A display that has a plurality of charged particles between a pair of substrates and displays images by moving the plurality of charged particles. The display comprises one substrate formed with a pixel electrode; the other substrate that is disposed to face the one surface and is formed with a counter electrode; a plurality of partitions for dividing the gap between the pair of substrates into a plurality of regions; and an insulating layer formed to have an insulating part and openings on the ...

A display device includes; a first group of bus lines for transmitting a display signal; a second group of bus lines for transmitting a scan signal and a display unit formed at an intersecting point between the first bus line and the second bus line. The first group and the second group of bus lines are formed in a matrix. The display device further includes switching elements which are selectively opened or closed, the switching elements being provided between the bus lines in the first group o...

In a display signal generating means in a display device for both the character display and the graphic display, address conversion means is provided for converting the addresses of one character in a plurality of lines of one character section of a memory field corresponding to a display panel into a predetermined address or addresses.

A display element for use with a display panel which includes a display surface structure having a number of such elements arranged in a vertical plane and each adapted for rotation about support arms provided on the opposite side surfaces thereof, thereby producing a display of a character, graph, pattern or the like on the display surface structure. The display element is formed with a plate-like (or four-cornered) block member having two (or four) display surfaces of different colors and one ...

A position detector 1 detects the position of a display screen 4, an image memory 2 stores image information, a selector 3 selects a portion of the image information stored in the image memory 2 in accordance with the position of the display screen 4 detected by the position detector 1 and supplies the selected portion to the display screen 4, and the display screen 4 displays the selected image information. The invention is characterized in that when it is assumed that the entire image informat...
