Abstract: This disclosure provides devices, apparatuses and methods of preventing incorporation of bright defects into an image generated by a display apparatus. A display apparatus may include a chromic film that is selectively activated, with the activated regions of the chromic film being colored, light blocking regions that overlie or underlie bright defect pixels of the display apparatus. The remainder of the chromic film is colorless and light transmissive. The chromic film may be provided as a coating on a substrate of the display apparatus. The chromic film may be selectively activated by exposing regions that overlie or underlie bright defect pixels to laser radiation. The laser radiation may induce a photochemical or thermally activated reaction in the chromic film, selectively changing the irradiated regions from colorless and light transmissive to colored and light blocking.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for displaying image frames. A smoothing process can be utilized for mitigating image artifacts similar to dynamic false contouring (DFC). In some implementations, were a display to transition from an field specific contributing color (FSCC) having only two component colors to a target FSCC with meaningful intensities of all three component colors, or vice versa, and that target FSCC remained constant over a series of image frames, DFC-like artifacts would be mitigated at the transition by gradually, over a first number of image frames in a series of image frames, reducing the intensities of all component colors of the FSCC to values at or near zero, before gradually increasing the intensities of the component colors included in the target FSCC to their final target values over a remainder of image frames in the series of image frames.

Abstract: This disclosure provides systems, methods and apparatus for reducing ambient light reflections from a surface of a display device in a power efficient manner. The display device includes a reflecting circular polarizer (RCP) and an absorbing circular polarizer (ACP) having the same polarity. The RCP provides light recycling functionality, while the ACP provides ambient light reflection suppression. In some implementations, the light generated by the display device is polarized by the RCP before it is incident on the ACP, which is located at the front of the display device. Because the polarities of the RCP and the ACP are the same, the ACP substantially passes all of the incident polarized light towards the front of the display device.

Abstract: This disclosure provides systems, methods, and apparatus for generating images on a display using a hybrid scalar-vector dithering process. The hybrid scalar-vector dithering process includes a combination of a scalar dithering process and a vector dithering process. In the scalar dithering process, at least one color subfield is dithered based on the data within just that color subfield. In the vector dithering process, data across multiple color subfields is dithered together. In some implementations, the color subfield processed by the scalar dithering process is a composite color subfield, such as white (W), yellow (Y), cyan (C) and magenta (M). The color subfields processed by the vector dithering process can be component color subfields, such as red (R), green (G), and blue (B) color subfields. In some implementations, an identical dither mask is applied in both the vector and scalar portions of the hybrid scalar-vector dithering process.

Abstract: This disclosure provides systems, methods and apparatus for reducing flicker in display devices. In some image formation processes, a controller can form an image by utilizing a set of color subfields and displaying subframes associated with each of the color subfields. In some implementations, the controller can determine a critical flicker frequency (CFF) associated with each subframe. The CFF for a subframe of a color is the minimum frequency at which the subframe of that color must be illuminated to avoid the perception of flicker by a viewer. If the CFF for any subframe is above an illumination frequency for that subframe, then the controller can employ flicker mitigation measures to reduce the perception of flicker of the subframe. In some implementations, the controller may carry out flicker mitigating measures such as dividing the display of subframes based on environmental factors such as ambient light.

Abstract: This disclosure provides systems, methods and apparatus for reducing flicker in display devices. In some image formation processes, a controller can form an image by utilizing a set of color subfields in displaying subframes associated with each of the color subfields. In some implementations, the controller may determine whether to divide or split the display of certain subframes based on environmental factors such as ambient light with or without concern for flicker. In some implementations, the controller may determine to divide or split the display of an x-channel subframe based on the ambient light. The controller can monitor the ambient light levels via an ambient light sensor, and compare the ambient light level to an ambient light threshold. If the ambient light levels go below the ambient light threshold, the controller can employ subframe division or splitting.
