ABSTRACT
Since the 1990s, there has been a substantial proliferation in the nature and form factors of video-and visually based displays. e range of devices that can be considered “computer displays” has expanded into new classes of mobile and at-screen device options. Furthermore, display technologies and performance capabilities are easier to evaluate in the context of their intended application. Consideration of

the following issues can narrow the search for candidate systems and can prevent needless frustration during system use:
Environment: Will the display be operated in sunlight or at night or in conned conditions? Application: Will the display present alphanumeric data, video images, graphics, or some combination? Task scenario: Is portability, handheld operation, or group viewing required? System characteristics: Are there critical operational constraints such as weight, volume, power, maintenance, or cost?
