Abstract: A mobile communication terminal that includes a display panel; a first touch panel provided on a surface of the display panel; a second touch panel provided on at least one surface of the mobile communication terminal other than the surface of the display panel; and a controller that controls the display panel based on at least one of a size and number of contacts corresponding to a touch input detected at the second touch panel.

Abstract: A display apparatus including a display section that includes a plurality of thin display devices formed at multiple layers such that their display screens overlap with one another, wherein at least one of the display devices closest to a viewing side of the display section is configured to be transparent, and control means for controlling each display of the plurality of display devices of the display section.

Abstract: A display device includes a display panel unit having predetermined viewing angle characteristics. An image data conversion unit is included that converts original image data to be displayed on the display panel unit so that a luminance difference in a low gray level region does not substantially change between before and after conversion and so that a luminance difference in a high gray level region changes in such a manner that a luminance difference obtained after conversion becomes smaller than a luminance difference obtained before conversion. A data holding unit holds predetermined oblique-view image data corresponding to the predetermined viewing angle characteristics of the display panel unit. An image combining unit combines image data obtained through conversion by the image data conversion unit with the predetermined oblique-view image data to generate composite image data. The composite image data is displayed on the display panel unit.

Abstract: A sensor-equipped display apparatus including a light-transmissive display screen, a sensor that detects light passing through the light-transmissive display screen, and a material that visually obscures the sensor when viewed through the light-transmissive display screen.

Abstract: A liquid crystal module including a polymer-dispersed liquid crystal device as a component of a transparent display, and an electronic apparatus equipped with the liquid crystal module. The liquid crystal module includes: a liquid crystal panel that performs gradation display between transparent color and white using the polymer-dispersed liquid crystal device; and a driving section that drives the liquid crystal panel. The driving section includes a gradation conversion section that relates a plurality of input gradation values between transparent color and white with a plurality of output gradation values between a minimum opacity and a maximum opacity individually. The gradation conversion section employs an S-shaped curve that defines the relation between the input gradation values and the output gradation values.

Abstract: A display apparatus includes: a display section including a transparent scattering layer switchable in accordance with a first control signal between a state in which incident light is transmitted in units of dots and a state in which incident light is scattered in units of dots, a transparent reflective layer switchable in accordance with a second control signal between a state in which incident light is transmitted and a state in which incident light is reflected, and a bonding layer that bonds the transparent scattering layer and the transparent reflective layer to each other; and a control signal generation section configured to generate the first and second control signals.

Abstract: A display device includes a display unit, a display control unit, and a control unit. The display unit includes a first and second glass plates, each formed with an electrode connected to a power supply and configured to transmit a light, and a light dispersing element sealed between the first and the second glass plates. The light dispersing element transmits the light when a voltage from the power supply is turned on, and disperses the light when the voltage is turned off. The display control unit controls a timing of turning the voltage on or off, or switching the voltage between positive and negative when the voltage is turned on. The control unit instructs the display control unit to set a display frame rate to a predetermined value during a standby mode, and set it higher than the predetermined value during an information display mode.

Abstract: A display device includes a first light-transmissive glass plate having a first electrode for connection to a power supply, a second light-transmissive glass plate having a second electrode for connection to the power supply, a light dispersing element sealed between the first and second glass plates for transmitting light when voltage is applied and dispersing the light when the voltage is not applied, a light-transmissive transparent element laminated on the second glass plate and having a predetermined refractive index, a light guide plate laminated on the transparent element and having a refractive index lower than the transparent element for surface-emitting the light toward a side viewed by a user, a light emitting part provided on a lateral side of the light guide plate for emitting light, and a display control part for turning on or off the voltage applied to the first and second electrodes.
