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.

A thin film display element (100) has at least one emissive area (103) in the display region (101) and a layer structure (104) comprising: a first patterned conductor layer (110) comprising a first display electrode (111) in the display region; a second patterned conductor layer (120) comprising a second display electrode (121) in the display region; and an emissive layer (130) between the first and the second conductor layers configured to emit light in the at least one emissive area. The patterned conductor layers further comprise a first touch electrode (141) and a second touch electrode (142) in the display region, the first and the second touch electrodes forming a touch sensor (140) for capacitive touch or proximity sensing.

A display driver (100) includes terminals (TSEG1 and TSEG2) and a drive circuit (130). The terminal (TSEG1) can be connected to a segment electrode (ESEG1). The terminal (TSEG2) can be connected to a segment electrode (ESEG2) whose area is larger than the area of the segment electrode (ESEG1). The drive circuit (130) outputs a PWM segment drive signal (SSEG1) to the terminal (ESEG1), and outputs a PWM segment drive signal (SSEG2) to the terminal (TSEG2). When the same effective voltage is applied to the segment electrode (ESEG1) and the segment electrode (ESEG2), the duty ratio of the segment drive signal (SSEG1) is smaller than the duty ratio of the segment drive signal (ESEG2).

A common driver 200 includes a voltage output circuit 160 that outputs an inspection voltage that is different between a first period and a second period to an inspection voltage output line Ld, and outputs a first voltage Va1 to a first segment electrode and a second voltage Va2 to a second segment electrode SE2 in the first period and the second period, a signal output circuit 140 that outputs, to a signal voltage output line Ls, a voltage of a first signal in the first period, and a voltage of a second signal in the second period, and an inspection circuit 170 that inspects whether or not an anomaly is present based on the voltage of the inspection voltage output line Ld and the voltage of the signal voltage output line Ls.

A display control device includes a first display capable of color display, a first controller performing reset control of the first display, and a second controller having less throughput than the first controller. The first controller executes reset control on the first display in a case of a first operation mode in which the first controller is active. The second controller executes reset control on the first display in a case of a second operation mode in which the first controller is inactive or in a case of detection of the first controller not operating normally.

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.
