The present disclosure provides a display panel, a method for driving the display panel, and a display device. The display panel includes a control unit including first and second processing circuits. A pixel circuit located within the fingerprint recognition region is connected to the first and second processing circuits of the corresponding control unit. In the fingerprint recognition mode, a pixel circuit located within the non-fingerprint recognition region receives a first light emission control signal, so that the light-emitting element does not emit light in first period and second sub-period and emits light in first sub-period. The second processing circuit provides a second light emission control signal, and a pixel circuit located within fingerprint recognition region responds to the second light emission control signal, so that the light-emitting element does not emit light in first period and emits light in first sub-period and second sub-period.

A method and system for calibrating brightness variation in a display involve measuring brightness levels of light emitters in the display. The light emitters are divided into different groups based on the measured brightness levels. Each group is assigned a sub-frame duration. Groups with higher brightness are assigned shorter sub-frame durations than groups with lower brightness. Calibration information is stored for driving the light emitters such that during a frame period of the display, the light emitters are activated for durations corresponding to the sub-frame duration of their corresponding group.

The present invention provides a display parameter adjusting method and an electronic device employing the method. The electronic device includes a display, a light source and a light receiver. The display parameter adjusting method includes: emitting a light beam to the light receiver by the light source; calculating a turbidity of a location of the display according to a first light intensity of the light beam received by the light receiver, wherein a propagation direction of the light beam emitted by the light source is parallel to a displaying surface of the display, and the location is beneath a water surface; and adjusting the display parameter according to the turbidity.

A head mount display device includes a display device and a processor. The display device includes an image compensator, a data driver, a scan driver, a timing controller, and a display panel. The image compensator receives an image data corresponding to a user's field of view and motion information, calculates a scaling value that controls a size of a masking area that controls a range of the user's field of view by masking a peripheral portion of an image corresponding to the image data based on the motion information, and generates compensation image data based on the image data and the scaling value.

A computer-implemented method, according to one embodiment, includes learning a rate of eye adaptation that a first user's pupil muscle adjusts. In response to a determination that the first user is moving from a first location having a first level of light illumination to a second location having a second level of light illumination, it is determined whether a difference in the levels has a potential for causing eye adaptation issues for the first user. In response to a determination that the difference in the levels has a potential for causing eye adaptation issues, a level of light illumination that will allow the first user's pupil muscle to adjust at the learned rate of eye adaptation is determined. A first representation of the second location is output for display on a mixed reality device worn by the first user upon the first user entering the second location.

In one embodiment, a first computing server receives a message from a client computing device. The message identifies an image to be displayed on the client computing device. The message is generated by a second computing server and received by the client computing device in response to a request sent by the client computing device to the second computing server for the identified image. The first computing server determines one or more adjustment parameters based on the display capabilities of the client computing device. The first computing server creates an adjusted version of the identified image based on the adjustment parameters, and sends the adjusted version of the identified image to the client computing device for display.

A portable device providing notice information and a method for providing the notice information thereof are provided. The portable device includes a display configured to be divided into areas respectively corresponding to types of notice information, and a controller configured to sense an event corresponding to the notice information, and control the display to activate pixels included in an area corresponding to a type of the notice information, and inactivate pixels included in an area not corresponding to the type of the notice information, among the areas, in response to the controller sensing the event.

A display device for an industrial sensor is provided, including an electronic display configured to display encoded information, the encoded information being information for retrieving device-related information about the sensor. An industrial sensor system, and a method for retrieving device-related information about a sensor of an industrial sensor, are also provided.

A display may be foveated to reduce power consumption and increase row scan timing margin. In one embodiment, the display includes pixels, where a first set of the pixels are formed to have a low resolution and a second set of the pixels are formed to have a high resolution. A first subset of the first set of pixels is formed in a first pixel cell layout and includes anodes formed in a first anode layout. A second subset of the second set of pixels is formed in a second pixel layout and includes anodes formed in a second anode layout. In another embodiment, the display similarly includes pixels formed to have a low resolution or a high resolution. The pixels of this embodiment may be formed in the same anode layout.

A transparent display device and a control method using the same are provided. The transparent display device includes a transparent display, a plurality of identification sensors, a scene sensor, and a controller. The identification sensors are configured to sense a user located at a first side of the transparent display to generate a plurality of identification data. The scene sensor is configured to sense scene information located at a second side. The controller obtains a user distance between the user and the transparent display, selects corresponding identification data generated by at least one of or multiple of the identification sensors according to the user distance, determines a location and a gaze direction of the user and a target object in the scene information according to the selected corresponding identification data, and presents target object information corresponding to the target object in the transparent display.
