In one example, a display is described, which may include a plurality of spaced light emitting device packages, a privacy gate having partition walls to partition each of the plurality of spaced light emitting device packages, and a control unit to selectively move the partition walls up or down relative to the plurality of spaced light emitting device packages to control a viewing angle of the display.

A multi-functional active matrix display comprises a transparent front sheet, a semi-transparent layer of light emissive devices adjacent the rear side of the front sheet and forming a matrix of display pixels, and a solar cell layer located behind the light emissive devices for converting both ambient light and internal light7 from the light emissive devices into electrical energy, the solar cell layer including an array of electrodes on the front surface of the solar cell layer for use in detecting the location of a change in the amount of light impinging on a portion of the front surface of the solar cell layer.

The operation of an automatic data input and query system is controlled by well-defined control data. The system exposes user interfaces enabling an administrator to interact with control data to modify the ongoing operation of the system. Certain control data determines the collection and treatment of data from various technology sources. A robust control interface is provided enabling the efficient and reliable adding on of new technology data sources. Once established, control data for a new technology data source may be packaged in a form for archiving or distribution. The system may support the export and import of such packages. Such packages may be created independently of the system.

A hidden display apparatus, system, and method. A display apparatus embodiment may include a face layer and a projection layer, with the projection layer positioned behind the face layer. The face layer may include a front side and a back side. The front side may include a first area configured to display high resolution images and a second area positioned around the first area. The first area and the second area may be made of the same material, and have similar color(s) and/or patterns. The projection layer may include a light source operative in an active mode and an inactive mode. When in the active mode, the projection layer may project light to the face layer to display images in the first area. When in the inactive mode, the face layer may be visually obscured so that the first area and the second area together display a colored surface.

Apparatus, methods, and program products are disclosed for operating a display in privacy mode. One apparatus includes a processor and a memory that stores code executable by the processor. The code is executable by the processor to detect an individual within an unauthorized zone in the field of view of a camera. The code is executable by the processor to operate a display in privacy mode in response to detecting the individual within the unauthorized zone. Methods and computer program products that perform the functions of the apparatus are also disclosed.

A display device includes a display panel, a display panel driving circuit, and a power management integrated circuit that generates driving voltages, receives driving set data from a timing controller, stores driving hex values corresponding to the driving set data in first internal registers, and determines voltage levels of the driving voltages based on the driving hex values. The power management integrated circuit divides the driving hex values into upper and lower decimal values, derives a result decimal value by applying the upper and lower decimal values to a first authentication-formula, generates a result hex value based on the result decimal value, compares an authentication hex value corresponding to authentication data received from the timing controller with the result hex value, and selectively operates in a normal mode or in a protection mode based on a comparison result between the authentication hex value and the result hex value.

The present disclosure discloses a display apparatus, a backlight source, and a light source module. The display apparatus includes a display panel and interference light sources which generate interference light on a display side of the display panel. The interference light is invisible light.

A user device having dynamic control of the privacy and brightness of a display sof a user device is described. The user device includes a processor that obtains information indicating whether a change to the brightness and/or viewing angle of the display is desired. In response to instructions from the processor requesting a change to the brightness and/or privacy of the display, a controller connected to the processor increases or decreases the display brightness and/or viewing angle by controlling a backlight included in the display.

A non-secure display area and a secure display area are set on a screen of a display section of a touch panel TP. A non-secure input area and a secure input area are set on a detection surface of a touch input detector of the touch panel TP. In settlement processing, in a display area where the non-secure display area and the secure display area are overlapped, amount information is displayed. A message for urging authentication information input and a PIN pad are displayed in the secure display area. An operator can safely input PIN information to secure the input area through the PIN pad displayed in the secure display area. Even when the secure portion and the non-secure portion are present together, the settlement terminal device can secure the security of input authentication information or the like to suppress the operator's mistake or incorrect operation.

A liquid crystal display panel includes first and second substrates, first pixel electrodes, second pixel electrodes, common electrodes, first auxiliary electrodes, and a liquid crystal layer. The second substrate is disposed opposite to the first substrate. The liquid crystal layer is disposed between the first and the second substrates. The first pixel electrodes, the second pixel electrodes, and the common electrodes are disposed on the first substrate. The first auxiliary electrodes are disposed on the second substrate. One of the first pixel electrodes is not overlapping one of the first auxiliary electrodes in a vertical projection direction. A driving method of the liquid crystal display panel includes setting a first voltage difference in a wide viewing mode and a second voltage difference in a narrow viewing mode between the first auxiliary electrodes and the common electrodes and, respectively. The first voltage difference is less than the second voltage difference.
