Display Design

A significant body of literature provides information on interface design. Although design is more of an art than a science, heuristics can be applied to determine the most efficient way of communicating data (Tufte, 1983, 1990, 1997). Many 

Visual clarity—The clarity with which the system displays information information displayed on the screen should be clear, well organized, unambiguous, and easy to read. 

Consistency—Consistency of the interface in terms of how it looks, the ways in which it presents information, and the ways in which users perform tasks the way the system looks and woiks should be consistent at all times. 

Compatibility— The system in question s compatibility with other related systems the way the system looks and works should be compatible with user conventions and expectations. 

Informative feedback— The level, clarity, and appropriateness of the feedback provided by the system users should be given clear and informative feedback on where they are in the system, what actions they have taken, whether these actions have been successful, and what actions should be taken next.

These refer to the control of a chemical process and include planning for familiar tasks (e.g., change type of fuel-firing in a furnace) or planning for familiar but infrequent tasks (e.g., start-up or shutdown a furnace). Methods of task analysis and error analysis can be used to analyze well-established strategies that operators use to perform procedural tasks and identify the user s information needs. An implication for display design would be that all information needed... 

In this section, we provide a brief introduction to the field of display engineering and the human-factors issues which dictate display design. We then assess how OLEDs measure up to the criteria necessary to achieve a commercially successful display technology. But first, we take a short detour to lay out the language used by display engineers and to provide a means of translating from the scientific units that wc have used up to now. 

The display contains 240 rows and 320 columns. The pixel size is 300 x 300 pm2 resulting in a display diagonal of 4.7 inches. An overview of the display design is shown in Fig. 14.5. All contacts to the display are situated on the left. The row electrodes are arranged horizontally and the column electrodes are arranged vertically. The three small blue rectangles are the contacts to the common electrode. 

Dashboards can be designed using simple tabular data presentations or using a sophisticated network-based system that allows the individual to select what data they wish to display. Design decisions are a function of the organizational needs and the available resources.

In display design, one is often concerned with the charge injected into a node of a circuit when a TFT used as a switch is shut off. Thus, one is led to consider not the small-signal capacitances, but rather the charges go Go and Qs associated... 

This rest of this section concentrates only on a few design guidelines that are especially important for safety. The reader is referred to the standard literature on display design for more information. 

Sherr s design was originally proposed for area displays but he discussed the special case of a linear display in 1976 The display design is shown in Fig 5b Two things should be noted in particular. The technique for connecting the high resolution electrodes in parallel is to fabricate meandering lines as shown in Fig. 5b This scheme will work for linear displays but not for area displays ... 

There have been a number of recent and well publicised accidents in which human error has played a prominent part. At Three Mile Island a combination of poor display design, bad maintenance and operator error led to the reactor core becoming uncovered and the release of radioactivity into the atmosphere. At the Ekofisk oil field incident a blowout preventer was installed upside down which resulted in an accident, following which widespread environmental pollution ensued. In both these cases the overall losses have been estimated in tens and hundreds of millions of pounds. These and similar incidents have brought sharply into focus the need to include an appraisal of human reliability and the factors which affect it when considering the safety performance of both large and small scale systems of work. ... 

Operator detects the alarm at HMI whose display design and alarm management design are vital in getting the operator s detection. Now logic solver — human intelligence comes in to action, as operator is correctly to understand the issue and use operator s expertise or experience to quickly determine the consequence and initiate corrective action. This is the diagnosis of the problem.

The t)q)e of display must meet the needs of the human being operating the machine or equipment and the display itself must be clear and as easy to read as possible. It should not overload the operator with too much data but must take into accoxmt the information needed and how quickly it has to be assimilated. The importance of getting this right is underlined by the fact that poor display design was a contributory factor in the nuclear power stahon incident at Three Mile Island. 

Workspace and environmental factors include system design recommendations relating to the aspects of the physical workspace and work environment that impact operator workload, such as interface and display design and noise, temperature, and ambience. 

Interface and display design—The displays and interfaces within the system should be designed considering the following issues ... 

Error at the blunt end (latent conditions) Management decision to have the surgical count performed by only one technician (no double check) Equipment designed with poor display design making it hard to identify numbers... 

By making displays flexible, the freedom of display design becomes spread borderless, based on their excellent portability, storability, and installability. As a result, a flexible display can create a variety of new human interfaces (Fig. 8.1). Therefore, it can be said that flexible displays form the ultimate evolution of flat-panel displays.
