TABLE OF CONTENTS Advanced display system design is an area of great technological interest across a broad range of industries. As a result, considerable engineering expertise is being directed toward improved displays of all types, from consumer television to specialized aeronautical applications. Key evaluation metrics for any display include the following:
Overall luminous efficiency
Viewability (brightness and contrast)
Uniformity of reproduction, both large- and small-area
Gray scale
Color capability, gamut, and accuracy
Life expectancy and reliability
Cost of the display device and supporting circuitry
Important technology trends for the principal display technologies include the following:
Cathode Ray Tube. In a cathode ray tube, a deflected electron beam is used to excite a cathodoluminescent phosphor. In this very mature technology, continued emphasis is being placed on achieving higher resolution, lower cost, sunlight viewability, and longer life, for both direct-view and projection devices. Improved computer modeling has led to smaller and more intense electron beams. Additional trends include continued emphasis on achieving flatter faceplates and wider deflection angles.
Liquid Crystal Display. In a liquid crystal display (LCD), an electric field is applied across a material having both liquid and crystalline properties. This field is used to modulate light by controlling the amplitude, wave vector, or phase vector of the device. LCDs are likely to dominate in low-cost vector graphic applications, particularly if low power consumption and overall physical size...
