In accordance with some embodiments, the render rate is varied across and/or up and down the display screen. This may be done based on where the user is looking in order to reduce power consumption and/or increase performance. Specifically the screen display is separated into regions, such as quadrants. Each of these regions is rendered at a rate determined by at least one of what the user is currently looking at, what the user has looked at in the past and/or what it is predicted that the user will look at next. Areas of less focus may be rendered at a lower rate, reducing power consumption in some embodiments.

A display device including a display panel to generate a real image, and an optical system. The optical system includes a plurality of lenslets, each having one cluster of object pixels, where the assignation of object pixels to clusters may change periodically in time intervals. The cluster emits light towards its corresponding lenslet and the emission is such that no light is sent to neighbor lenslets to avoid cross-talk between channels. Each channel projects a partial virtual image into the eye. The combination of all partial virtual images creates a virtual image. In a preferred embodiment, the partial images of neighbor channels are interlaced, which allows for a higher resolution. Additionally, each channel may be devoted to a single color, avoiding color filters and allowing for a higher efficiency.

The disclosure provides a light cabinet, including multiple light boards and multiple light-board controllers. The light boards form a first light-board array of the light cabinet. The light-board controllers are arranged one-to-one on the light boards. The light-board controllers of the light boards in a first column of the first light-board array are connected in series to form a first controller string. The output terminal of the first controller string is connected electrically to an input terminal of a second controller string in a corresponding column of a second light-board array of another light cabinet. The input terminal of the first controller string is connected electrically to a first output terminal of a video data splitter (or an output terminal of a third controller string in a corresponding column of a third light-board array of yet another light cabinet).

A mapping method for a fulldome display, including convert an original image into a deformed image corresponding to the fulldome display; divides the deformed image into at least one first image, at least one second image, and at least one third image; incorporate the third image with the second image to form at least one intermediate image; display image pixels of the first image on display pixels of at least one first displaying module of the fulldome display based on a first mapping relation; display image pixels of the intermediate image on display pixels of at least one second displaying module of the fulldome display based on a second mapping relation. In this way, the increased image pixels of the third image could be transmitted and be displayed.

To provide a semiconductor device, a liquid crystal display device, and an electronic device which have a wide viewing angle and in which the number of manufacturing steps, the number of masks, and manufacturing cost are reduced compared with a conventional one. The liquid crystal display device includes a first electrode formed over an entire surface of one side of a substrate; a first insulating film formed over the first electrode; a thin film transistor formed over the first insulating film; a second insulating film formed over the thin film transistor; a second electrode formed over the second insulating film and having a plurality of openings; and a liquid crystal over the second electrode. The liquid crystal is controlled by an electric field between the first electrode and the second electrode.

It is an object to provide a display device which can favorably display a image without delayed or distorted signals. The display device includes a first gate driver and a second gate driver. The first gate driver and the second gate driver each include a plurality of flip flop circuits and a plurality of transfer signal generation circuits. Both the flip flop circuit and the transfer signal generation circuit are circuits which output a signal inputted to a first input terminal with a half clock cycle delay. In addition, an output terminal of the transfer signal generation circuit is directly connected to a first input terminal of the flip flop circuit in the next stage. Therefore, delay and distortion of the signal which is inputted from the transfer signal generation circuit to the flip flop circuit can be reduced.

A screen projection control method and an electronic device are provided. The method includes: displaying a target control when the electronic device establishes a communication connection with a screen projection display device; receiving a first operation performed on the target control, and determining a to-be-projected target application in response to the first operation; sending displayed content of the target application to the screen projection display device through the communication connection for display; and receiving a second operation performed on the target control, and switching the target application to run in the background in response to the second operation.

There is disclosed in one example a video processor, including: an input buffer to receive an input image; a slicer circuit to divide the input image into a plurality of N vertical slices; N parallel input buffers for de-rasterization; N parallel image scalers, wherein each scaler is hardware configured to scale in a raster form, one of the N vertical slices according to an image scaling algorithm; N parallel output buffers for rerasteriztion; and an output multiplexer to combine the scaled vertical slices into a combined scaled output image.

Methods and apparatuses are disclosed herein for performing tone mapping and/or contrast enhancement. In some examples, a block mapping curve is low-pass filtered with block mapping curves of surrounding blocks to form a smoothed block mapping curve. In some examples, overlapped curve mapping of block mapping curves, including smoothed block mapping curves, is performed, including weighting, based on a pixel location, block mapping curves of a group of blocks to generate an interpolated block mapping curve and applying the interpolated block mapping curve to a pixel to perform ton mapping and/or contrast enhancement.

An information processing device sets a region of interest in an imaging region and determines a region to be displayed from the region of interest according to a state of an object.
