There are provided display controllers and driving methods related to those described in US Published Patent Application No. 2013/0194250. These include (a) a display controller having an update buffer, means for removing from the update buffer pixels not requiring updating, and means to ensure that pixels having certain special states are not removed from the update buffer; (b) a method of driving a bistable display wherein, in a pixel undergoing a white-to-white transition and lying adjacent another pixel undergoing a visible transition, there is applied to the pixel one or more balanced pulse pairs and at least one top-off pulse; (c) a method of driving a bistable display by overlaying a non-rectangular item over a pre-existing image content and then removing the item, where only pixels in the region of the item perform transitions (including self-transitions); and (d) a method of driving a bistable display in which a proportion of background pixels not undergoing an optical change are subjected to a refresh pulse to correct optical state drift.

There are provided methods for driving an electro-optic display having a plurality of display pixels, a such method includes detecting a white-to-white graytone transition on a first pixel; and determining whether a threshold number of cardinal neighbors of the first pixel are not making a graytone transition from white to white, or if the first pixel is a color pixel, and apply a first waveform.

A driving controller of a display device, the controller including a segment divider configured to divide the image signal into a plurality of segments and define a predetermined number of adjacent segments among the plurality of segments as a segment block, an image signal adder configured to add up a gray scale value of the image signal of each of the predetermined number of adjacent segments and output the added-up gray scale values, an average gray scale calculator configured to receive the added-up gray scale values and output an average gray scale value, a correction circuit configured to output corrected added-up gray scale values obtained by adding a weight value to each of the added-up gray scale values on the basis of the average gray scale value, and a driving frequency determiner configured to determine the driving frequency of the display device on the basis of the corrected added-up gray scale values.

Aspects of the invention are directed towards sensing environmental parameters associated with an item and displaying information related to the item. One or more embodiments of the invention describe sensing, by one or more sensors, at least one environmental parameter associated with an item and validating, by a processor, the sensed environmental parameter with a pre-configured data stored in a memory. One or more embodiments of the invention further describe displaying information related to the item based on said validation, the information displayed on an electronic display coupled to the item.

A process for the formation of an assembly comprising a structured or compacted porous film (c) comprising a) application of a porous film (d) onto an elastic substrate (a) in a stretched state such that a reversible adhesion of the film on the stretched substrate (a) occurs, and b) relaxing the substrate (a) with the applied film thereon to obtain a structured or compacted porous film (c), c) applying a support material (e) to a part of the structured or compacted film (c) so that the structured or compacted film to which no support material (e) is attached is releasable.

A digital license plate supporting both access and analysis of vehicle relevant information is disclosed. The digital license plate includes sensors that provide status data to a processor in the digital license plate. A power path control module can initiate power state changes and adjust power depending on system state as determined by at least one the multiple sensors. In some embodiments a temperature control module is connected to a temperature sensor and configured to modify heat relevant display parameters as critical temperatures are approached.

The present invention provides a solution for a highlight or multicolor display device, in which each display cell can display high quality color states. More specifically, an electrophoretic fluid is provided which comprises three types of pigment particles, having different levels of size, threshold voltage or charge intensity.

Provided is a display panel having a display area including a first display area and a second display area. The display panel includes: a substrate; an array layer; a display layer including light-emitting elements each including an anode, a light-emitting layer and a cathode that are sequentially stacked; the light-emitting elements comprises first light-emitting elements and second light-emitting elements; a state switching layer located at a side of the display layer facing away from a display surface of the display panel and located in the first display area, wherein in a direction perpendicular to the display panel, the state switching layer overlaps the first light-emitting elements; the state switching layer is switchable between a first state and a second state, and the state switching layer has a smaller light transmittance in the first state than in the second state; and an optical element.
