Display device
To provide a display device including a flexible panel that can be handled without seriously damaging a driver circuit or a connecting portion between circuits. The display device includes a bent portion obtained by bending an element substrate. A circuit for driving the display device is provided in the bent portion and a wiring extends from the circuit, whereby the strength of a portion including the circuit for driving the display device is increased and failure of the circuit is reduced. Furthermore, the element substrate is bent in a connecting portion between an external terminal electrode and an external connecting wiring (FPC) so that the element substrate provided with the external terminal electrode fits the external connecting wiring, whereby the strength of the connecting portion is increased.
TRANSPARENT DISPLAY SYSTEM AND OPERATION METHOD THEREOF
A transparent display system including a transparent display and a computation module is provided. The computation module is coupled to the transparent display. The computation module determines whether a display image displayed on the transparent display can be recognized based on display information and background information. If it is determined that the recognizability of the display image is poor, the haze of the background image displayed on the transparent display is adjusted. An operation method of the transparent display system is also provided.
LIGHT BEAM DIRECTION CONTROL DEVICE
A control circuit is configured to: change a dispersion state of the electrophoretic particles by controlling voltage across the first transparent electrode and the second transparent electrode to change a range of exit direction of light transmitted through the light transmissive regions and the dispersion medium; apply direct voltage at a first voltage value across the first transparent electrode and the second transparent electrode to change the range of exit direction from a narrow range to a wide range; measure luminance of light transmitted through the light beam direction control panel during application of the voltage at the first voltage value; and increase the voltage value to be applied across the first transparent electrode and the second transparent electrode in a case where the measured luminance of the transmitted light is lower than a target value.
Display device and method of fabricating the same
A constitution of the display device of the invention is shown in the following. The display device includes a pixel unit including TFTs of which the active layer contains an organic semiconductor material for forming channel portions in the opening portions in an insulating layer arranged to meet the gate electrodes. The pixel unit further includes a contrast media formed on the electrodes connected to the TFTs for changing the reflectivity upon the application of an electric field, or microcapsules containing electrically charged particles that change the reflectivity upon the application of an electric field. The pixel unit is sandwiched by plastic substrates, and barrier layers including an inorganic insulating material are provided between the plastic substrates and the pixel unit. The purpose of the present invention is to supply display devices which are excellent in productivity, light in weight and flexible.
Opacity filter for display device
An optical see-through head-mounted display device includes a see-through lens which combines an augmented reality image with light from a real-world scene, while an opacity filter is used to selectively block portions of the real-world scene so that the augmented reality image appears more distinctly. The opacity filter can be a see-through LCD panel, for instance, where each pixel of the LCD panel can be selectively controlled to be transmissive or opaque, based on a size, shape and position of the augmented reality image. Eye tracking can be used to adjust the position of the augmented reality image and the opaque pixels. Peripheral regions of the opacity filter, which are not behind the augmented reality image, can be activated to provide a peripheral cue or a representation of the augmented reality image. In another aspect, opaque pixels are provided at a time when an augmented reality image is not present.
Two particle electrophoretic laminate for use with smart windows
A laminate which can serve as either a smart window or a smart mirror is formed using first and second substrates coated with transparent first and second electrodes which are separated by foraminous layer and a third grid-like linear electrode insulated from the first and second electrodes The foraminous layer includes spacers defining a cell space which is filled with a colloidal ink having first and second particles. The first particles have a positive charge and a first color and second particles having a negative charge and a second color different from the first color. By altering the voltages of the first, second and third electrodes, one can achieve different light transmission characteristics which, for example, can alter the color temperature of the light transmitted through the laminate or enhance reflective colors.
Optical sheet, screen, and display apparatus
An optical sheet, a screen, and a display apparatus capable of reducing speckles are provided. An optical sheet (50) includes a particle layer (55) including a transparent retaining part (56) having a predetermined thickness and a particle (60) that is accommodated in a cavity (56a) formed in the retaining part (56) and includes a first portion (61) and a second portion (62) having different dielectric constants. The first portion (61) includes a transparent first main portion (66a) and a first diffusion component (66b) that diffuses light. The second portion (62) includes a transparent second main portion (67a) and a second diffusion component (67b) that diffuses light. The first diffusion component (66b) and the second diffusion component (67b) have a diameter d satisfying the following conditional expression (1):
0.1 md15 m(1).
ELECTRO-OPTIC DISPLAYS INCLUDING REDOX COMPOUNDS
An electro-optic display having a viewing surface through which a user views the display, a bistable, non-electrochromic electro-optic medium, and at least one electrode arranged to apply an electric field to the electro-optic medium, the display further comprising at least 10 micromoles per square meter of the viewing surface of at least one compound having an oxidation potential more negative that about 150 mV with respect to a standard hydrogen electrode, as measured at pH 8, where the compound
BACKPLANES WITH HEXAGONAL AND TRIANGULAR ELECTRODES
Active matrix backplanes including an array of hexagonal electrodes or an array of triangular electrodes. Because the backplane designs route the gate lines along the periphery of the electrodes there is less cross talk with the surface of the electrode. The disclosed designs simplify construction and control of the electrodes and improve the regularity of the electric field above the electrode. Such backplane electrode designs may be particularly useful in electrowetting on dielectric (EWoD) devices and electrophoretic displays (EPD).
PATTERN CHANGING SHEET, WALKING GUIDANCE SYSTEM, AND MOVING SPEED REDUCTION DEVICE
A pattern changing sheet includes: lenticular lenses in number corresponding to one wavelength of the pattern changing sheet and disposed with the bus-line pitch to in the direction orthogonal to the optical axis; and a pattern layer opposed to the lenticular lenses on the rear face of the lenticular lenses, the pattern layer having a gradation pattern (dots) disposed in the bus-line pitch L.sub.0. The gradation pattern includes bright dots and dark dots in the bus-line pitch to in the disposing direction. The viewer views the display pattern that is a connection of the corresponding dots of the lenticular lenses depending on the viewpoint position, and the display pattern progresses at a predetermined speed scale-factor of the movement of the viewpoint. This configuration creates and provides a pattern changing sheet having a high degree of freedom and depending on the intended use.
