An electronic picture frame and an image display method thereof are provided. In the electronic picture frame, a plurality of images are arranged and displayed on one side of a screen, and among the plurality of images, an image at a particular position is enlarged and displayed. Alternatively, a screen is divided into a plurality of sub-screens, so images stored in each of a plurality of storage areas can be displayed on a respective sub-screen. Accordingly, the images stored in the plurality of storage areas can be displayed on the electronic picture frame in diverse forms.

A display device of the present disclosure includes an image display device and a control unit, in which the image display device includes an image formation device, and an optical device that displays an image emitted from the image formation device in front of an observer while superimposing the image on a real image of an outside world, the control unit controls an operation of the image formation device, and in a case where a black display edge that is an edge of an area where black is displayed exists in the image, the control unit performs reversing processing and luminance increasing processing of the black display edge.

A brightness parameter correction method and device and a brightness compensation system. The method includes: obtaining a first to-be-tested brightness parameter of a designated sample display panel at a first gray level; obtaining a first deviation parameter between the first to-be-tested brightness parameter and a reference brightness; calculating a correction coefficient based on the first to-be-tested brightness parameter and the reference brightness parameter when the first deviation parameter is greater than a first preset standard threshold, the correction coefficient being such that a corrected first deviation parameter between a corrected first to-be-tested brightness parameter and the reference brightness parameter is less than or equal to the first preset standard threshold; obtaining a second to-be-tested brightness parameter of a target display panel at the first gray level; and correcting the second to-be-tested brightness parameter using the correction coefficient to obtain a corrected second to-be-tested brightness parameter.

The disclosure provides a display device and a driving method thereof. The display device includes a light emitting module and a display panel. The light emitting module includes an optical sensor and multiple light emitting diodes (LEDs). The LEDs are adjacent to the optical sensor. The LEDs emit red, green, and blue light. The LEDs dynamically convert brightness of the red, green, and blue light. The display panel is disposed on the light emitting module. The display device of the disclosure may achieve a full-screen display or have a higher resolution.

The present invention embraces a system, device, and method for adding lighting effects to augmented reality (AR) content (i.e., virtual objects). Light sensors in an augmented reality (AR) system monitor an environment's lighting conditions to acquire lighting data that can be used to create (or update) virtual light sources. Depth sensors in the AR system sense the environment to acquire mapping data that can be used to create a 3D model of the environment while tracking the system's location within the environment. Algorithms running on a processor may then add the virtual light sources to the 3D model of the environment so that, when AR content is created, lighting effects corresponding to the virtual light sources can be added. The resulting AR content with virtual lighting effects appear more realistic to a user.

A liquid crystal display (LCD) device includes an LCD panel with a number (N) of pixel elements for displaying an image. A dimming panel includes N dimming elements. The dimming panel has a first mode to apply a uniform dimming to the N dimming elements to provide a privacy function for the LCD device. The dimming panel further has a second mode to a apply a per-element dimming to provide a local dimming function for the LCD device.

A display, system and method of providing a display are described. The display includes sets of microLEDs. Each set of microLEDs corresponds to one of a plurality of pixels of the display and produces a combination of light that forms a color of the corresponding one of the pixels. Lenses control an emission angle and emission profile of the light emitted by the sets of microLEDs. Each set of microLEDs has a red microLED that emits red light, a green microLED that emits green light, a blue microLED that emits blue light, and another microLED that emits light along a red-green locus. The red-green locus light is selected to enhance efficiency at a white point to compensate for reduced emission from the red microLED dependent on a size of the red microLED.

A display device can include a display panel to display an input image across a first subpixel region and a second subpixel region; a display panel driver to supply pixel data of the input image to subpixels of the display panel; a light source disposed under the display panel in an area overlapped by the second subpixel region; and a controller to drive the light source in an emission permitting section set within a non-driving period of a group of subpixels among the subpixels that are disposed in at least a portion of the second subpixel region.

To provide a display device capable of displaying a plurality of images by superimposition using a plurality of memory circuits provided in a pixel. A plurality of memory circuits are provided in a pixel, and signals corresponding to images for superimposition are retained in each of the plurality of memory circuits. In the pixel, the signals corresponding to the images for superimposition are added to each of the plurality of memory circuits. The signals are added to the signals retained in the memory circuits by capacitive coupling. A display element can display an image corresponding to a signal in which a signal written to a pixel through a wiring is added to the signals retained in the plurality of memory circuits. Reduction in the amount of arithmetic processing for displaying images by superimposition can be achieved.

The disclosed system modifies luminance of a display associated with a selective screen. The display provides a camera with an image having resolution higher than the resolution of the display by presenting multiple images while the selective screen enables light from different portions of the multiple images to reach the camera. The resulting luminance of the recorded image is lower than a combination of luminance values of the multiple images. The processor obtains a criterion indicating a property of the input image where image detail is unnecessary. The processor detects a region of the input image satisfying the criterion, and determines a region of the selective screen corresponding to the region of the input image. The processor increases the luminance of the display by disabling the region of the selective screen corresponding to the region of the input image.
