A de-jaggy processing method includes dividing a display area of a display into a plurality of sub-areas; providing a first table composed of gray-level weights associated with corresponding luminances of each primary color for each said sub-area; providing a second table composed of distance-gain weights each correspondingly associated with a distance between a sub-pixel and a reference point; and obtaining a corrected luminance of a sub-pixel of a pixel by multiplying an original luminance of the sub-pixel by a corresponding gray-level weight and a corresponding distance-gain weight.

Briefly, a method for verifying the visual perceptibility of a display is provided. An intended message is written to a bistable display. Pixels that comprise portions of the message are measured and evaluated to determine if the message actually displayed on the bistable display was perceptible by a human or a machine. In some cases, information regarding the message actually perceivable from the display may be stored for later use. Responsive to determining that a message is perceivable or not perceivable, alarms may be set, one or more third parties notified, or additional display features may be set.

Described are various embodiments of a light field device, pixel rendering method therefor, and vision perception system and method using same. One embodiment describes a method to adjust user perception of an image portion to be rendered via a set of pixels and a corresponding array of light field shaping elements (LFSE), the method comprising: projecting an adjusted image ray trace between a given pixel and a user pupil location to intersect an adjusted image location for a given perceived image depth given a direction of a light field emanated by the given pixel based on a given LFSE intersected thereby; upon the adjusted image ray trace intersecting a given image portion associated with the given perceived image depth, associating with the given pixel an adjusted image portion value designated for the adjusted image location based on the intersection; and rendering for each given pixel the adjusted image portion value associated therewith.

A stain compensation method using a screen calibration system includes generating first parameter data including first data blocks, each defined by at least one emission area, by photographing a display surface, generating second parameter data including second data blocks, the second data blocks being generated by merging first data blocks that are adjacent to each other in one direction and have an identical average grayscale value, and storing the second parameter data in a memory.

In the use of a display of a converter, method for operating a converter, and converter, the converter having an address code switch, in particular on its housing, and in an actuation of the address code switch and during a subsequent, predefined period of time, a respective value corresponding to the respective switch position of the address code switch is displayed by the display. Operating information of the converter is displayed in all other cases.
