8results about How to "Prevent peeping" patented technology

This application discloses a display panel and display device, belonging to the field of display technology. In the sharing mode, the regular display unit is turned on, and the light emitted from the regular display unit forms a clear and visible image. In the privacy mode, the privacy display unit is turned on, and the regular display unit is turned off. The light emitted from the privacy display unit is emitted through the privacy opening, forming a directional narrow-angle beam that is only visible within a small viewing angle range, preventing others from peeping. In the top view direction of the display panel, the geometric center of the first opening of the dimming layer is offset from the geometric center of the light-emitting opening of the privacy display unit, thereby improving the symmetry of the privacy light effect on the corresponding two sides of the privacy display unit.

The method includes: collecting first operation information from user feedback based on received trigger information; obtaining corresponding coordinate base points based on the first operation information; acquiring multiple operation options from the current operation interface information of the self-service device; rearranging the operation options according to the coordinate base points using a random sorting algorithm to generate virtual operation options; generating voice guidance information based on the virtual operation options and the coordinate base points; obtaining input options based on second operation information from user feedback based on the voice guidance information and the virtual operation options; and completing the user self-service based on the input options.

The utility model relates to the technical field of display equipment, and discloses a display device and terminal equipment. The display device comprises a display screen, a camera module, an angle adjusting mechanism and a control module, the display screen is provided with a dynamic grating layer, the camera module is used for collecting face information and pupil information of a user in front of the display screen, and the angle adjusting mechanism is used for adjusting the angle of the display screen so that the display screen can directly face the user. The control module can judge whether the user is the user according to the face information and can adjust the dynamic grating layer according to the pupil information so that the display center of the display screen can directly face the pupil center of the user. According to the utility model, other personnel can be effectively prevented from peeping the screen information of a user, the privacy security of the user is protected to the greatest extent, additional shielding is not needed during sensitive operations such as password input, the user experience is good, the screen light and visual angle are adjusted along with the sight line of the user, the user is more humanized and intelligent, and the operation is more convenient and natural.

The application discloses a display panel and a display device. The display panel comprises a first light-emitting unit and a second light-emitting unit arranged adjacently. The first light-emitting unit comprises a first light-emitting element and a first transmission part. The second light-emitting unit comprises a second light-emitting element and a blocking part. When the first light-emitting element works and the second light-emitting element is closed, the first base color visible light emitted by the first light-emitting element can be transmitted from the corresponding first transmission part, and the display panel is in a normal display mode. When the first light-emitting element and the second light-emitting element both work, the first base color visible light emitted by the first light-emitting element and the first base color visible light under a side viewing angle emitted by the second light-emitting element can both be transmitted from the first transmission part, thereby enhancing the side viewing angle light emission of the display panel. Meanwhile, the first base color visible light under a normal viewing angle emitted by the second light-emitting element can be blocked by the corresponding blocking part, and the normal viewing angle light emission of the display panel is not affected. The display panel is in a peep-proof mode, and the peep-proof function is realized.

Provided is a laminate that is excellent in the effect of preventing peeping from an oblique direction and has excellent directional anisotropy in which the transmittance in the front direction is excellent and the light absorption characteristics in the oblique direction are reduced, and a display device including the laminate.

Embodiments of the present application provide a display panel and a display device. The display panel comprises a substrate, a display light emitting device, a privacy light emitting device, a shielding layer, a display pixel circuit and a privacy pixel circuit. In a direction perpendicular to a plane in which the substrate is located, the shielding layer completely covers the privacy light emitting device, and the shielding layer does not overlap with the display light emitting device. The display pixel circuit is electrically connected with the display light emitting device, and the privacy pixel circuit is electrically connected with the privacy light emitting device. In a normal display mode, the display light emitting device emits light, and the privacy light emitting device does not emit light. In a privacy display mode, the display light emitting device and the privacy light emitting device both emit light. The privacy pixel circuit and the display pixel circuit are both electrically connected with a same voltage signal line, and / or the privacy pixel circuit and the display pixel circuit are both electrically connected with a same scanning signal line. The present application can realize an active privacy function of the display panel, and is conducive to reducing the structural complexity of a peripheral circuit of the display panel.

The utility model discloses a kind of tourism scenic spot management wisdom screens, it is related to tourism scenic spot management equipment technical field, including: wisdom screen, its display side is used to display and operation;Two side plates, it is respectively rotationally arranged at the display side edge of the wisdom screen, when two the side plate is attached on the display surface of the wisdom screen, the movable end of two The side plate contacts;Top plate, it is rotationally arranged at the display side top of the wisdom screen;When this scheme outwardly rotates side plate, the top of side plate extrudes top plate and makes top plate upwardly overturn, until the top of side plate slides into slot, it can be shielded to side, prevent peeping, also can shield external strong light, it is convenient to see display content, in the process of rotation, the linkage design of side plate and top plate does not need additional locking device, rely on the cooperation of structure itself can realize the stable switching of state, both simplify operation procedure, and reduce the use of spare parts, reduce the probability of failure occurrence.
